Description

The invention relates to a modular tunnel formwork device for the concrete lining of tunnel walls. CN 106 640 131 B discloses a modular tunnel formwork device.

Until now, the concrete lining of tunnel walls was carried out using tunnel formwork devices that had to be assembled and dismantled on site. The assembly and dismantling of the device is carried out individually at each construction site and takes considerable time, which considerably increases the overall costs of a tunnel project.

It is therefore the object of the invention to create a tunnel formwork device which enables faster assembly and dismantling and also easier transport of the tunnel formwork device between different construction sites.

This object is achieved by a modular tunnel formwork device according to claim 1 and a mobile formwork arrangement according to claim 16 and a tunnel concreting device according to claim 17. Advantageous further training is the subject of the associated dependent claims. Advantageous developments of the invention are also disclosed in the description and in the figures.

According to the invention, the tunnel formwork device has a modular structure and comprises at least two modules, which are arranged one behind the other in the longitudinal direction of the tunnel formwork device and can be releasably connected to one another, the at least two modules each having a frame part, and the frame parts of the modules connected to one another form a frame of the tunnel formwork device. In addition, the tunnel formwork device has at least two support structures that can be connected to its frame and are spaced apart from one another in the longitudinal direction of the tunnel formwork arrangement for supporting the frame on a tunnel floor. These support structures are preferably arranged on the outer frame parts that are spaced apart in the longitudinal direction, so that the frame is securely supported at its longitudinal ends by the support structures on the tunnel floor.

In addition, the frame carries at least two support cylinders at least two positions spaced apart from one another in the longitudinal direction, which are preferably at least partially designed as hydraulically length-adjustable support cylinders, which with in the longitudinal direction running longitudinal beams can be connected. These in turn carry tunnel formwork elements of the tunnel formwork device, which form the tunnel formwork.

According to the invention, a tunnel formwork device is thus formed by at least two modules, preferably by at least three modules connected to one another in the longitudinal direction of the tunnel formwork device, the length of which can be adjusted by the number of modules used. This has the advantage that the length of the tunnel formwork device can be individually adjusted as required by the number of intermediate modules selected. It should be noted that the longitudinal direction of the tunnel formwork device coincides with the tunnel direction.

Optionally, it can also be provided that the width of each module can be varied, for example by adapter pieces or by a hydraulic adjusting mechanism, so that not only the length of the tunnel formwork device in the longitudinal direction of the tunnel, but also the width of the tunnel formwork device can be adjusted in accordance with the width of the modules . The working width of the modules can be easily varied by appropriately adjusting the support structures and the length-adjustable hydraulic support cylinders so that both narrow and wide tunnel shapes can be formed. The tunnel shape is adjusted by appropriately adjusting the length of the support cylinders, which are preferably hydraulically telescopic. By appropriately varying the standing width of the support structures, which are preferably adjustable both in their distance in the transverse direction and in their height, an adapted stability can be achieved even in wide tunnels. The vertical support cylinders do not have to be hydraulically adjustable in length, since the height adjustment of the tunnel formwork device can also be achieved via the support structure.

Due to the fact that the entire tunnel formwork device has a modular structure, it can be transported comparatively easily, i.e. using common transport vehicles, such as semi-trailers or semi-trailers of freight trains. For example, if the length of a module in the tunnel direction is between 1 and 4 m and the width is between 3 m and 10 m, conventional semi-trailers can be used to transport the modules because the maximum width and length regulations for transport are not exceeded .

The modules preferably comprise two end modules, which form the two ends of the tunnel formwork device in the longitudinal direction, and at least one intermediate module to be arranged between the end modules, which can be connected to at least one of the two end modules in a positive and/or non-positive manner. The end modules can be designed specifically for the load-bearing function, e.g for fastening the support structures, while the intermediate modules are designed to support the tunnel formwork through the support cylinders and the longitudinal beams. This distributes the different necessary functions of the tunnel formwork device, such as the load-bearing function and support function of the tunnel formwork, across different types of modules, which is more economical and more efficient than if one module has to fulfill all of these functions.

Preferably, the support structure is height-adjustable and is formed in particular by hydraulically telescoping support legs. The tunnel formwork device can thus be adapted to different tunnel heights. Preferably, the distance between the support legs can also be adjusted transversely to the tunnel direction, so that the support structure can be adapted to different tunnel widths. If the support structures are height adjustable, the vertical support cylinders do not necessarily need to be designed as hydraulically length-adjustable support cylinders, since the height adjustment can then be realized via the support structures. The height adjustability also has the advantage that the tunnel formwork device can enter the tunnel with a reduced height, i.e. lowered, so that the tunnel formwork does not collide with tunnel sections that have already been boarded up.

The two support cylinders are preferably each supported on the frame part of at least two modules. For example, the support cylinders can be formed on the frame part of each intermediate module, so that a number of support cylinders corresponding to the number of intermediate modules is provided to support the longitudinal beams, which in turn support the tunnel formwork elements against the tunnel wall.

Preferably, the frame part of each module, preferably only the intermediate modules, carries at least six support cylinders, two of which protrude at least approximately vertically upwards, and four of which are directed horizontally or obliquely upwards or downwards. In this way, the circular arc-shaped tunnel formwork elements are supported over the circumference at at least six points on the tunnel wall, which makes it possible to securely support the tunnel formwork elements to form the tunnel formwork.

Preferably, at least one work platform is mounted on the frame, in particular on the frame of the two end modules, which is movable, in particular height-adjustable and/or laterally adjustable via a hydraulic lifting device, and is carried on the frame. In this way, the correct formation of the tunnel formwork can be checked at all points. In addition, this at least one movable work platform helps with the positioning of the tunnel formwork elements and during maintenance or assembly work. The lifting devices can preferably be controlled via a/the common control arrangement of the tunnel formwork device or separately via controls of the work platforms.

Preferably, two work platforms are arranged on the frame of each end module on both sides of the tunnel formwork device, so that the entire span of the tunnel formwork can be approached with these two work platforms.

The support cylinders are preferably connected to load sensors, so that the load absorbed by each support cylinder can be monitored on a central control arrangement and, if necessary, pressure peaks can be reduced by appropriately controlling the support cylinders. Of course, each support cylinder is preferably provided with a load sensor. The pressure peaks are reduced by controlling the concreting speed.

Preferably, at least one of the at least two support cylinders is pivotally articulated to the frame or the frame part of a module, so that the support points for the tunnel formwork elements can be adapted to the local conditions. Alternatively or additionally, the support strut can be connected to the support cylinders via a pivoting mechanism, so that the longitudinal beams can optimally reach behind the tunnel formwork elements, even if the support by the support cylinders is not exactly vertical from below.

In an advantageous development of the invention, the longitudinal beams have hydraulically operated stamps, particularly at their ends, for support on the tunnel wall or the tunnel ceiling. As a result, the longitudinal beams are fixed in an absolutely immovable manner between the supporting structures of the frame of the tunnel device and the stamps, which are hydraulically controlled and rest firmly against the tunnel walls or the tunnel ceiling. When backfilling the tunnel formwork elements with concrete, there is no spatial change in the position of the tunnel formwork elements because they are clamped in an absolutely stationary manner.

Preferably, each support structure is formed by two support legs, which can be releasably connected to the frame, preferably to the outermost frame parts of the end modules or intermediate modules in the longitudinal direction. For example, only the end modules can have the fastening structures for the support structures or support legs, which ensures, on the one hand, that the support structures are arranged at the two ends of the tunnel formwork device, and thus securely supporting the tunnel formwork device arranged in between. On the other hand, the intermediate modules can only have those structures that are required to support the tunnel formwork, i.e. the hydraulic support cylinders. As already stated, these legs are both height adjustable and their distance can be adjusted.

In an advantageous development of the invention, only the frame parts of the intermediate modules carry the hydraulic support cylinders and the frame parts of the end modules each carry at least one work platform and the support structures, with the work platform projecting beyond the front of the support structures.

In order to ensure a simple structure of the tunnel formwork device, each module, preferably each end and intermediate module, has integrated connections for pneumatics and/or hydraulics and/or electrical systems.

The hydraulic support cylinders are connected to the longitudinal beams via at least one bolt, in particular a conical bolt, in order to ensure the firm connection of the hydraulic support cylinder and the support strut.

In an advantageous development of the invention, the tunnel formwork device has a control module with a control arrangement for the tunnel formwork device, which can preferably be connected to the frame. The control module can be formed, for example, by a cabin of the tunnel formwork device or a control box in which the control arrangement is arranged in order to be easy to operate and to protect it from dirt and moisture in the tunnel. This control arrangement then has all the necessary interfaces for the hydraulics, electrics and pneumatics of all modules and is able to receive the force measurement data from the load sensors of the support cylinders and to carry out the adjustment and actuation of the support cylinders centrally for the entire tunnel formwork device.

Preferably, a working platform is supported via a hydraulic lifting device on the frame parts of the end modules and/or intermediate modules, which can be raised relative to all frame parts by means of the lifting device. The working platform preferably extends over the entire length of the tunnel formwork device. When lowering using the lifting device, the work platform can be lowered onto the frame parts.

The invention also relates to a mobile formwork arrangement with a tunnel formwork device, as described above, and with at least three transport vehicles, each transport vehicle having a trailer to accommodate at least one module, and further components such as support structures, work platforms, longitudinal beams, control module, etc. To transport a tunnel formwork device, a number of transport vehicles are necessary, which correlates with the number of modules. This has the advantage that a tunnel formwork arrangement of very different lengths can be easily transported by a corresponding number of transport vehicles. Preferably, the two end modules and each intermediate module have fastening elements for securing them to the trailer, particularly in their corner or edge areas. For example, one or two modules can be transported on a trailer.

At least one trailer of a transport vehicle preferably contains fastening elements for receiving the support structures and preferably one trailer of another transport vehicle contains fastening elements for the longitudinal beams.

In a further advantageous development of the invention, one of the transport vehicles contains a trailer for the control module, preferably a cabin or a control box, in which the central control arrangement is arranged, the central control arrangement for controlling the electrics, hydraulics and, if necessary, pneumatics of the tunnel formwork device is trained. The control module, which is preferably designed as a cabin, with the central control arrangement can preferably be connected to the frame of the tunnel formwork device, for example in the area of a work platform.

As already explained above, a conventional truck semi-trailer or a semi-trailer of a freight train can serve as the transport vehicle. The tunnel formwork device of any length can therefore be easily transported over long distances using an appropriate number of wagons or trucks. This facilitates universal use even in very remote locations.

The invention also relates to a tunnel concreting device comprising a tunnel formwork device of the above type and at least one concrete pump, which is controlled by the control arrangement for controlling the support cylinders of the tunnel concreting device, at least one delivery line of the concrete pump being connected to the space between the tunnel formwork elements and the tunnel wall. The concrete pumps are preferred can be controlled depending on the signals from load sensors, which are arranged in connection with the support cylinders. In this way, a tunnel of almost any cross-sectional shape and length can be boarded efficiently, with the control of the concrete pumps dynamically taking into account the degree of filling of the space between the tunnel formwork and the tunnel wall.

Preferably, the length of the hydraulic support cylinders can be adjusted in length by at least a factor of 1.5, preferably at least by a factor of 2, which is possible using several telescopic stages.

It is obvious to those skilled in the art that the embodiments of the invention described above can be combined with one another in any way.

The modular tunnel formwork device 10 according to the invention is described below with reference to Fig. 1 to 3 described. The modular tunnel formwork device 10 consists of two end modules 12a, 12b and seven intermediate modules 14a-14g extending between the two end modules 12a, b, which are firmly connected to one another. Each end module 12a, 12b contains a frame part 16a, which is positively and/or non-positively connected to the frame parts 16b of the intermediate modules 14a-g, as well as the frame parts 16b of the intermediate modules 14a-g to one another, preferably in the same way are non-positively connected to a common frame 20 of the tunnel formwork device 10. The frame parts 16a of the end modules 12a, b can be connected to support structures 18 in the form of two support legs each, which securely support the frame 20 of the entire tunnel formwork device 10 formed by the frame parts 16a, b of all modules 12a, b, 14a-g on the tunnel floor . At the lower end of each support leg 18 there is a base 19 with rollers, which can be moved along a path or rails in the longitudinal direction of the tunnel during the tunnel formwork. The connection between the modules 12a, b and 14a-g or between their frame parts 16a, b is detachable, so that the individual modules can be transported separately to the construction site. The support legs 18 are height-adjustable via a hydraulic telescopic mechanism 23, while their mutual distance in the transverse direction (horizontally transverse to the tunnel direction) can be adjusted via a horizontal telescopic mechanism 21 or by insertable adapter pieces.

Two working platforms 22a, b and 22c, d are supported on the frame parts 16a of the end modules 12a, b via a hydraulic lifting device 24, which can be raised relative to the frame parts 16a of the end modules 12a, b by means of the lifting devices 24 and can also be moved laterally. so that inspections or assembly work on the tunnel formwork elements, on the longitudinal beams and the support cylinders can be carried out via these work platforms 22a-d. The frame 20 extends at least approximately over the entire length of the tunnel formwork device 10. Two vertical hydraulic support cylinders 26a, b are preferably attached to the frame 20 for each intermediate module 14ag, so that when the frame 20 is raised via the hydraulic telescopic mechanisms 23 of the support legs 18 The vertical support cylinders 26a, b must also be raised for height adjustment. In this way, 10 tunnels of different heights can be boarded and filled with concrete using the tunnel formwork device. The vertical support cylinders therefore do not even need to be hydraulic and length-adjustable.

Each frame part 16b of the intermediate modules 14a-g carries two support cylinders 28a, b pointing obliquely downwards as well as two horizontally extending support cylinders 30a, b, which extend symmetrically towards the tunnel sides facing away from one another in relation to the center of the tunnel. The free ends of the support cylinders 26a, b, 28a, b, 30a, b are each connected to longitudinal beams 32a-f, which in turn carry circular arc-shaped tunnel formwork elements 33 ( Fig. 4 ), which in their The entire tunnel formwork 37 forms. The tunnel formwork device 10 shown thus controls six support cylinders or struts 32a-f, which extend over the entire inner circumference of the tunnel wall to be concreted, that is, generally over a range of 150 to 270 degrees (see Fig. 2 and 4 ). The tunnel formwork elements 33 can be supported on the tunnel floor 35 via separate support bodies 36. Alternatively, the support cylinders 32a and 32f pointing obliquely downwards can form the lowest support which will form the tunnel formwork 37 composed of the entirety of the tunnel formwork elements 33. The support of the tunnel formwork 37 by the support elements 26a, 28a, 30a and by the support cylinders 32a, 32b, 32c is in Fig. 4 clarified. It can also be seen in this illustration that the vertical support cylinders 26a, b do not have to be aligned exactly vertically, just as the horizontal support cylinders 30a, b do not have to be aligned exactly horizontally. These can be adjustable in their fastening angle on the frame parts of the intermediate modules 14a-g at least in a small range of, for example, +/- 15 degrees, while the support cylinders pointing obliquely downwards can preferably be adjustable in a larger angular range of, for example, 45 degrees. The support struts 26a, b are preferably fixed rigidly, ie not pivotally, to the frame 20, so that the tunnel formwork is fixed in its angular position, and the tunnel formwork 37 can therefore not tilt while the tunnel formwork device is moving.

It is unnecessary to say that preferably all support cylinders 26a, b, 28a, b, 30a, b are provided with load sensors 38, which can be connected via data lines 40 to the central control arrangement 44 of a control module 42 of the tunnel formwork device 10. The control arrangement evaluates the data from the load sensors 38 and preferably controls the support cylinders depending on the recorded data in order to optimally position the tunnel formwork 37 and to operate concrete pumps to fill the space between the tunnel wall and the tunnel formwork 37 in such a way that there are no excess loads the support cylinders or the tunnel formwork elements 33 come. On the tunnel formwork device 10, six longitudinal beams 32a-f are each supported by seven hydraulic support cylinders 26a, b, 28a, b, 30a, b, which are connected to the seven individual intermediate modules 14a-g. In this way, the forces of the tunnel formwork 37 can be effectively absorbed by the tunnel formwork device 10, with the introduction of force in the driving state ultimately taking place via the support structures 18 into the tunnel floor 35. The two ends of each support strut 32a-f are provided with hydraulically actuated stamps 34, which are controlled in such a way that they are supported on the tunnel walls, whereby all longitudinal beams 32a-f between these and the support structures 18 are firmly defined in their position, which leads to reproducible formwork results.

The control module 42 preferably contains a cabin 46, preferably with at least one window 48, in which the control arrangement 44 is positioned. In this way it is effectively protected against dirt and moisture on the construction site. The control module 42 can be positioned anywhere on the tunnel formwork device 10. Preferably it can be connected to the support structure 18 or to a frame part 16a, b of an end or intermediate module 12a, b, 14a-g. The control arrangement is connected to the hydraulics for actuating all support cylinders and to concrete pumps for filling the cavity between the tunnel wall and the tunnel formwork 37 in order to optimally control the tunnel formwork process.

The end modules 16a, 16b are preferably assigned work platforms 25a, b, which project beyond the front of the support structures or support legs 18, so that the ends of the tunnel formwork 37 and the entire tunnel formwork device can be clearly seen.

As the Fig. 5 to 7 clarify, can be in the Fig. 1 to 4 Tunnel formwork device shown can be effectively transported, in the present case by nine transport vehicles 50a-i in the form of semi-trailers. For example, the left transport vehicle 50a carries the longitudinal beams 32a-f of the transport device, while the two transport vehicles 38b and 38c arranged to the right of it carry parts of the working platform 22. The next right transport vehicle 50d carries the two end modules 12a, b and the transport vehicles 50e, 50g, 50h and 50i carry the seven intermediate modules, while the fourth transport vehicle 50f from the right carries the four support legs 18 of the tunnel formwork device 10.

In addition to an intermediate module 14, the control module 42 can also be transported onto the middle transport vehicle 50e, i.e. a cabin 46 with the control arrangement 44 of the tunnel formwork device 10, so that all essential components of the tunnel formwork arrangement 10 can actually be transported on the transport vehicles 50a-i and on site in a simple manner Can be mounted in this way. An additional transport vehicle can optionally be provided for electrical, hydraulic and pneumatic infrastructure elements, such as lines, hydraulic cylinders, support cylinders and the like. At least one transport vehicle may have a crane for assembling the modules 12, 14 and the support structure 18 and all other components.

Fig. 8 shows the complete tunnel formwork device 10 in cross section with the frame 20 carried on the support legs 18, with the support cylinders 26a, b, 28a, b and 30a, b arranged on the frame 20, those carried on the support cylinders and located in the longitudinal direction of the Tunnel formwork device 10 (= tunnel direction) extending longitudinal beams 32a-f, the tunnel formwork elements 33 stretched between them, which together form the tunnel formwork.

Fig. 9 shows the possible working area 52 of the tunnel formwork device, ie which tunnel cross sections can be covered with the tunnel formwork device 10, by adjusting the length of the support cylinders 26a, b, 28a, b and 30a, b, by adjusting the vertical telescopic mechanisms 23 for the height adjustment of the support legs 18, by adjusting the horizontal telescopic mechanism 21 or installing adapter pieces for the mutual spacing of the support legs 18. The vertical longitudinal beams 26a, b can also not be adjustable in length, with the height adjustment then taking place solely via the vertical telescopic mechanism 23 for the support legs 18.

This adjustability is in Fig. 10 shown for a flat tunnel tube. The vertical telescopic mechanism 23 for the support legs 18 is slightly extended here, so that a low support height results. For this purpose, adapter pieces 21 are inserted into the support legs 18, which ensure a greater distance between the two support legs 18 in the transverse direction or width direction of the tunnel formwork device 10. In addition, the hydraulic support cylinders 28a, b running obliquely downwards and the horizontal support cylinders 30a, b are extended far, so that a small height but a large width of the tunnel formwork 37 formed from the tunnel formwork elements 33 results.

Fig. 11 shows the setting of the corresponding components for an egg-shaped, narrower tunnel wall.
