Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary road resin foam block for constructing a temporary road by laying a plurality thereof and a connected body thereof.

[0002]

BACKGROUND OF THE INVENTION When constructing buildings on soft ground, or when constructing ordinary buildings or excavating ruins, these work sites are often separated from the main road. In such a case, it is necessary to temporarily install a road for transporting the base material and the like required for the work between the main road and the work site. These temporary roads are removed at the end of work, and are generally constructed by renting arable land between the main road and the work site. Therefore, after a certain period of time, the temporary road has been removed and the original condition (for example, paddy field,
It must be restored to the condition of cultivated land such as fields.

At construction sites of buildings, large construction vehicles such as backhoes or large crane vehicles are used, and they have a large weight. For the work, heavy objects such as steel frames are lifted or moved. As a result, a heavy load is applied to the ground that supports this, and the temporary road must ensure safety even for such work.

Conventionally, a construction method by embankment has been adopted for the construction of such a temporary road. This method, from the good ground of the construction vehicle can run to the work site,
For example, a temporary road is formed by digging into a groove approximately in the width of a construction vehicle, laying a civil engineering sheet or the like in the groove, laying gravel on the sheet, embankment, and tamping this.

However, temporary roads are often constructed on the land leased above, and in such a case,
When the work is completed, it is necessary to remove this embankment and restore it to its original state. In the method of constructing a temporary road by embankment, it is generally necessary to transport a large amount of soil from a place away from the temporary construction site or to compact this soil, and after the completion of construction, remove the embankment used. Sometimes the site needs to be restored to its original condition, and in some cases the embankment must be discarded, which makes the work troublesome, prolongs the construction period, and increases the construction cost.

When the ground for constructing the temporary road is weak, even if the trench is dug and the earth is filled, the side surface of the trench is still the soft ground, so that when a heavy construction vehicle runs, The impact on the surroundings of the constructed temporary road cannot be ignored, such as the embankment being moved to the side by the load of the vehicle and lifting the houses on the side of the temporary road.

As a temporary road construction method for solving the above problems, for example, a temporary road construction method using a resin foam block such as foamed styrene has been adopted. This construction method is a lightweight embankment method in which resin foam blocks are connected to each other and stacked to form a base for embankment instead of embankment.

This lightweight embankment method has the following advantages, for example. (1) Since the resin foam block is extremely lightweight, workability is good. (2) In this lightweight embankment method, the embankment load can be reduced compared to the temporary road construction method using embankment.
The subsidence of the foundation ground can be reduced.

(3) Since the resin foam block has the self-supporting property, the lateral pressure can be reduced as compared with the case of the embankment, so that the slope or the like is less likely to collapse and the existing structure is less affected. .

(4) Since the construction method using this resin foam block does not require a large machine for construction of the temporary road,
Construction can be performed close to important structures, and the impact on the surrounding environment is small.

As described above, the temporary road using the resin foam block has an advantage that it is easy to construct and the temporary road can be easily removed. However, since the resin foam block has a small number of uses, the resin foam block conventionally used to construct a temporary road is
Since it was discarded as it is, the method of constructing the temporary road using the resin foam block has a problem that the cost is higher than that of the conventional embankment method.

In order to reduce the cost, the resin foam block should be used repeatedly, but the resin foam block actually used for constructing the temporary road is missing at the edges, corners, etc. Not only is it difficult to reuse, but when it is stacked and stored for reuse, blocks with such defects are less stable and cannot be stored so high. . Therefore, the use of the conventional resin foam block increases the storage cost, so that it cannot be effectively reused.

[0013]

It is intended to provide a resin foam block for temporary roads, which can reduce costs by repeated use.

A second object of the present invention is to provide a resin foam block connecting body which can easily construct a temporary road.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a plan view showing an embodiment of a temporary road resin foam block according to the present invention, and FIG. 2 is a schematic view showing a state in which the temporary road resin foam block of the present embodiment is connected.

The resin foam block 1 for temporary roads is shown in FIG.
As shown in FIG. 3, the resin foam 2 has a rectangular cross section, and the net-like body 3 around which the resin foam 2 is wound. Specific examples of the resin foam 2 used in the present invention include expanded polystyrene, expanded polyurethane, expanded polyvinyl chloride and expanded polyolefin.

Since the temporary road block of the present invention is made of resin foam, it is lightweight and easy to handle as a whole.
Further, by utilizing the buoyancy, the subduction does not occur even on soft ground.

The resin foam 2 shown in FIG. 1 is a rectangular parallelepiped having a rectangular cross section, but it may be a cube. Further, in the present invention, the size of the resin foam is not particularly limited, but a resin foam having a large size of, for example, 2 m × 1 m × 0.5 m is preferable in terms of work efficiency.

The resin foam 2 can be wound directly with a net-like body, but it is preferable to coat the surface of the resin foam with a synthetic resin film or the like. That is, the temporary road block of the present invention directly placed on the ground at present,
Although covered with a net-like body, this block
Since it comes into contact with the ground through the net-like body, the resin foam in this portion is easily damaged. For example, when a stump of rice and the like come into contact with this block, the stump or the like pierces the block and the block is damaged.

Therefore, the surface of the resin foam which is most easily damaged can be covered with a synthetic resin film or the like to increase the strength of the surface of the resin foam. Furthermore, as shown in FIG.
It is preferable to stack the hard plate-like body 33 on the surface 32 (which may be covered with a synthetic film or the like) of the resin foam 31 that is in contact with the ground 30. A plywood, a resin plate, etc. can be used as this hard plate. The thickness of the hard plate-like body 33 varies depending on the material forming the plate-like body, but is usually about 1 to 20 mm. This hard plate 3
3 and the resin foam 31 can be laminated by bonding with an adhesive or by heat fusion. The laminated resin foam in which the hard plate-like bodies are laminated in this manner is wound around the net 34, and the adjacent resin foam block and the wire 3
Locked at 5.

As the material of the net-like body 3 constituting the resin foam block, polyolefin, polyamide resin,
Synthetic resins such as polyurethane resin, polyester resin, vinyl chloride resin and polyester resin are preferably used. It is particularly preferable to use polyolefin. The mesh shape of the net-like body 3 is not particularly limited. Further, the mesh (opening) of the net-like body 3 may be of a size such that it can be easily connected to the adjacent resin foam block 1. This net-like body may be one in which twisted yarns, which are aggregates of synthetic resin fibers, are bound together, or may be one in which synthetic resin films of a predetermined width are stacked vertically and horizontally and the intersections are bonded or fused. However, a wide film may be punched out so that stitches are formed. FIG. 1 shows an example in which a net-like body made of a net in which twisted yarns are bound is used.

A resin foam block is manufactured by tightly winding a resin foam with such a net and sticking the ends of the wound net to the wound net. You can

Since the resin foam block 1 of this embodiment has a structure in which the resin foam 2 as described above is wound in the form of a net, it has the effect of preventing damage to the resin foam 2.
In such a resin foam block 1 of this embodiment, a plurality of resin foam blocks 1 are arranged at a temporary road construction site or a storage location such as a warehouse as shown in FIG.
The net-like bodies 3 at both upper end portions of the resin foam blocks 1 adjacent to each other are bound and locked by the wire 4, while the resin foam blocks 1 adjacent to the opposite sides of the resin foam blocks 1 are connected to each other. The net-like body 3 at the lower end portion and the net-like body 3 at the lower end portion of the resin foam block 1 are bound together by a wire 4 and locked, so that adjacent resin foam blocks 1 can be easily joined together. Be connected. As a method of connecting the adjacent resin foam blocks 1, in addition to the method of bundling and locking as described above, for example, as shown in FIG. 5, the net-like bodies 3 of the adjacent resin foam blocks are engaged with each other. The wire 18 is pushed to be connected to each other, and both ends of the wire are formed into a ring shape 17 to prevent the wire from falling off, and the wire 18 can also be used as a hanging wire for carrying the resin foam block as described later.

Further, the net-like bodies at both upper ends of the adjacent resin foam blocks may be locked at a plurality of positions with wires to form each wire into a ring shape. Instead of, the net-shaped body may be locked at a plurality of positions with an elastic body such as rubber to form a ring shape.

When the resin foam block 1 is stored, the resin foam blocks 1 connected as described above are used.
In the connected state, the sheets are folded and stacked so that the surfaces having the net-like bodies 3 locked by the wires 4 are face-to-face and stacked on the pallet. The resin foam blocks 1 stacked in this way are forklifts,
It is transported by trucks and stored in warehouses for repeated use. The number of resin foam blocks 1 that are folded in the connected state can be appropriately determined depending on the size of the resin foam blocks 1.

When constructing a temporary road using the resin foam blocks 1 that are folded in a connected state,
In this state, the resin foam block 1 is transported to the temporary road construction site, and if the resin foam block 1 is expanded on the site, the plurality of resin foam blocks 1 are connected in the horizontal direction.
Therefore, the temporary road can be installed only by connecting the resin foam block 1 folded in the above-described connected state to the resin foam block 1 folded in the other connected state. , Individual resin foam blocks 1
There is no need to connect everything. For this reason, it is possible to shorten the connection work time of the resin foam block 1 at the temporary road construction site.

This resin foam block 1 is a block 1
Since the net-like body 3 that accommodates the resin foam block 1 covers the resin foam block 1, the resin foam blocks 1 can be stably stacked and the storage space can be effectively used.

The present invention has been described above based on a preferred embodiment thereof, but the resin foam block for temporary roads of the present invention is not limited to the above embodiment, and is a net-like body and this net-like body. It suffices if it has a configuration including a wound resin foam. Further, the temporary road resin foam block connected body of the present invention is not limited to the above-mentioned embodiment, and is a resin foam block having the above-mentioned configuration, as long as it can be folded in a connected state. Good.

For example, in the present invention, the resin foam blocks may be connected in the lateral direction, and the resin foam blocks may be connected in both the longitudinal direction and the lateral direction. Similarly, in the folded resin foam block connection body of the present invention, the resin foam blocks may be connected in the lateral direction. However, since the resin foam block connected body connected in both the longitudinal direction and the horizontal direction cannot be folded, it is necessary to release the connection in either one direction in order to fold such a connected body. .

In order to connect the resin foam blocks adjacent to each other, it is necessary to lock the net-shaped bodies of both the resin foam blocks, and the locking means is the net-shaped bodies of both the resin foam blocks. The wire foam 4 is not limited to the wire 4 of the above embodiment, as long as it can be easily and surely locked and the connected resin foam blocks can be folded in the connected state.

An example of a method for constructing a temporary road using the resin foam block of the present invention is shown below. In order to construct a temporary road using the resin foam block 1 as described above, the planned construction portion of the temporary road is made flat to some extent, and the resin foam block 1 is laid on it.

Further, as shown in FIG. 6, a plurality of resin foam blocks 1 wound with a net-like body 3 are connected at their respective side edge portions by using a locking tool 4 such as a wire. The body 13 can also be used. FIG. 6 shows a connecting body in which four resin foam blocks 1 are connected by wires so as to be foldable. In FIG. 6, the second and third resin foam blocks 1 from the top are connected by wires on the back surface side of the blocks. This block connection body 13
When, for example, four resin foam blocks are connected, as shown in FIG. 6, they are folded in four stages and carried in. With this folded block connected body, the hook of the crane is hooked on the hanging wire 17 provided at the end of the wire that engages each resin foam block, and the block connected body is lifted.

As shown in FIG. 4, the suspended block connecting body 13 is gradually lowered and laid while positioning the blocks on the temporary road planned position. Similarly, other block connection bodies are also laid. Since the block connection body and the other block connection body are not connected to each other, it is preferable to form a temporary connection between them after the installation.

After mounting the block connecting body so as to have a predetermined distance in this way, an iron plate (reconstruction plate) or the like is laid on the upper surface of the connecting body. The temporary road constructed in this way is
It has the excellent property that it is easy to install but high in strength.

For example, in the removal and restoration work of the temporary road constructed as described above, after removing the reconstruction plate 16,
The resin foam block 1 located at the end of the block connection body 13 after the temporary connection formed between the block connection body and another block connection body is released to form individual block connection bodies.
The hanging wire 17 is hooked and lifted, and the wire 17 is gradually lowered onto a loading platform such as a truck, folded as shown in FIG. 5, transferred to a predetermined place, and stored in a folded state.

In the above method, a plurality of resin foam blocks are connected in advance to construct a block connection body before the temporary road is constructed, and the block connection body is used. However, in the present invention, this method is used. Of course, the resin foam blocks 1 may be individually laid on the temporary road installation scheduled positions, and adjacent resin foam blocks 1 may be connected so as to be foldable.

Further, the temporary road resin foam block of the present invention can be modified in various ways.

[0041]

The resin foam block for a temporary road according to the present invention has a structure in which a resin foam block having a rectangular cross section is wound with a net-like body, and therefore, during transportation, construction of a temporary road or use. It is less likely to be damaged inside, the block size can be increased, and it can be reused, so the cost can be reduced by repeated use.

Further, in the resin foam block, since the surface of the resin foam is loosened in the form of a net, it can be stably stacked and the storage space can be effectively utilized.

Since a plurality of blocks are already connected in the resin foam block connection body for temporary road according to the present invention, the block connection work time at the temporary road construction site can be greatly shortened, and furthermore, the temporary connection work can be performed. When the road is removed, it is not necessary to release the connection for all the resin foam blocks, so that it is possible to shorten the connection release work time of the resin foam blocks.
