Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel drainage structure. Specifically, for example, it is formed on a structure such as an artificial ground, a basement, an underground parking lot, and rainwater and the like that fall onto the structure can penetrate from joints, and the drained rainwater and the like can be stably discharged for a long period of time. It is a drainage structure that can be performed and is easy to maintain.

2. Description of the Related Art Water such as rainwater accumulated on a structure such as an artificial ground, a basement, an underground parking lot not only deteriorates the durability of the structure, but also causes a situation that rainwater enters the structure. Therefore, it is desired to drain this efficiently.
On the other hand, when an exterior part such as a sidewalk is formed on the structure, it is functionally desired that the rainwater that has fallen into the exterior part quickly permeates and drains without flowing over the surface.

In response to such a demand, a drainage structure having a sectional view shown in FIG. 2 has been conventionally proposed. The drainage structure includes an exterior panel 1 arranged to form an empty joint 2, a concrete layer 3, a water-permeable layer 15 and a waterproof layer 14 made of gravel, and the empty joint 2 and the drainage layer 1
5 has a structure in which it is communicated with a communication portion 6 filled with a mesh member. Incidentally, 16 is an adhesive layer.

[0004]

However, in the above drainage structure, coarse particles of foreign matter such as leaves and stones are clogged in the gaps of the exterior material layer, which not only spoils the appearance but also is not easy to remove. Further, since the water passage portion is composed of a net-like member, fine particles of foreign matter such as sand are easily clogged, and the drainage capacity deteriorates in long-term use. Further, the gravel layer forming the drainage layer also has a problem that the drainage capacity is deteriorated during long-term use, like the knitted member. In particular, foreign substances clogged in the drainage layer cannot be practically removed.

[0005]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and a space is provided between the exterior material panels, and a drainage pipe is embedded in the lower portion in parallel with the space joint. By connecting the drain joint with the drain joint and connecting a drainage system to one end of the drainage pipe, the drainage treatment capacity of rainwater and the like dropped on the exterior panel can be increased, and Provided is a structure for drainage capable of supplying cleaning water into a drainage pipe by connecting a water supply system to an end thereof, and capable of extremely easily removing foreign matters in the drainage pipe and void joints. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to these accompanying drawings.

FIG. 1 is a schematic view showing a typical embodiment of the drainage structure of the present invention. Further, FIG. 3 is a perspective view (partially cutaway view) showing an example of a specific structure of the void joint and the drainage pipe formed by the exterior panel of the present invention.

The drainage structure of the present invention has an open joint 2 formed by an exterior panel (indicated by a broken line in the drawing) 1.
And a drainage pipe 3 is arranged below the void joint 2 in parallel to the void joint, the void joint 2 and the drainage pipe 3 are communicated with each other by a hollow communication portion 6, and one end of the drainage pipe 3 is connected to the drainage pipe 3. The drainage system 4 is connected to the water supply system 5 at the other end.

In the present invention, the exterior panel is made of a known exterior material used as an exterior material for sidewalks and the like, and is used without particular limitation. For example, a water-impermeable member such as concrete, natural stone, a resin molding, a metal, or a water-permeable member such as porous concrete having continuous voids is appropriately used.

In the present invention, the width of the joints 2 formed by the exterior panel 1 and the intervals between the joints 2 may be appropriately determined according to the drainage capacity. Generally, the width of the void joint 2 is preferably 5 to 30 mm, and the gap between the void joints is preferably 50 to 300 cm.

In the present invention, the void joint 2 is shown in FIG.
As shown in Fig. 2, it is generally formed in a linear shape and arranged so as to be arranged in parallel, but it may be formed in a curved shape, a rectangular shape, or the like by changing the shape of the exterior panel. It is possible. Further, although it is possible to configure each void joint so as to intersect, it is preferable to form each void joint so as not to intersect for ease of construction.

The exterior panel 1 is, as shown in FIG.
It is general that a concrete layer 7 is formed as a base and is fixed to the concrete layer 7 by an adhesive layer (not shown) such as mortar.

In the present invention, the drainage pipe 3 is provided below the empty joint 2. The diameter, cross-sectional shape, etc. of the drainage pipe are not particularly limited, and are appropriately determined according to the target treatment capacity. Generally, equivalent diameter 100 to 30
About 0 mm is appropriate in terms of ensuring drainage capacity and cleaning effect during water supply, which will be described later. In addition, the cross-sectional shape of the drainage pipe is generally circular, but in addition, oval, square,
A shape such as a triangle or a polygon can also be adopted.

The drainage pipe 3 is 1/200 to 1/50 with respect to the horizontal plane so that the drainage system side described later becomes lower.
It is preferable to incline with the gradient of.

The method for fixing the drainage pipe 3 is not particularly limited. Generally, as shown in FIG. 3, a method of embedding and fixing in a support member 8 such as concrete or soil is adopted. Further, as another fixing method, there is also a mode in which the concrete layer 7 is supported by a supporting structure to form a space, and a drainage pipe is supported by a fixture in the space.

In the present invention, the communicating portion 6 for communicating the empty joint 2 and the drainage pipe 3 is not particularly limited, but in order to improve the drainage capacity of rainwater and the like flowing into the empty joint,
It preferably has a cross-sectional area of 80% of the open area of the void joint. In this case, the communication part 6 may be provided continuously to the void joint 2 as shown in FIG. 1, or may be provided in a plurality of sections. The width of the above-mentioned communicating portion 6 may be appropriately determined, but it is generally sufficient that the width is substantially the same as the width of the void joint 2. In the embodiment shown in FIG. 3, the communication part 6
Are formed by penetrating the support member 8 and the concrete layer 7.

The drainage structure of the present invention may be constructed by using a single drainage unit formed by the void joint 2, the communicating portion 6 and the drainage pipe 3, or by arranging a plurality of them as shown in FIG. You may comprise. When using a plurality of drainage units, it is general that each drainage pipe 3 is connected by a communication pipe 13 to be connected to a drainage system and a water supply system described later, but if necessary, each drainage pipe 3 It is also possible to connect each to the drainage system and the water supply system. Further, in this case, it is preferable to provide a pressure adjusting means such as an orifice for adjusting the pressure between the drainage pipes of the communication pipe on the water supply side so that each drainage pipe can be supplied with more uniform pressure than the water supply system.

In the present invention, the drainage system 4 having a known function of treating the water from the drainage pipe 3 is adopted without particular limitation. For example, it is common to have a drainage structure such as an underdrain such as a fume tube or an open drain with a lid.

The water supply system 5 is not particularly limited as long as it has a function of allowing water to be pressed into the drainage pipe 3. For example, it comprises a water storage tank, a pump connected to the water storage tank, and a joint connecting the pump and the drainage pipe 3. The pump and the drain pipe do not have to be always connected, and it is preferable that the pump and the drain pipe can be cut off. In the above water supply system, the supplied water pressure and amount of water are such that the foreign matter in the drainage pipe 3 moves to the drainage system 4, and most of the foreign matter blocked between the empty joints 2 is discharged together with water from the empty joints. It is preferable to secure sufficient water pressure and water amount.

The method for producing the drainage structure of the present invention is not particularly limited. A typical manufacturing method will be specifically described with reference to the embodiment shown in FIG.

First, a collar-shaped stopper 1 having a drainage pipe 3 provided on its side surface on a waterproof layer 14 formed on a structure.
By attaching a support tool 12 having a height adjusting mechanism to the position 1, a fixed position is secured. The upper part of the drain pipe is opened like a slit, and the guide plate 9 is continuously formed on the upper part of the opening. After inserting a plate-shaped body having a thickness that can be inserted into the gap between the guide plates 9, the drainage pipe 3 is buried by a support member 8 such as concrete or soil. In this case, at least around the plate-shaped body, a support member that hardens is used, and after the curing, the plate-shaped body is taken out to form the communication portion 6 in the support member 8. Therefore, as the plate-like body, polypropylene, fluororesin, or the like, which has a relatively weak adhesion to concrete, is preferably used. In addition, by adjusting the upper end of the inserted plate-like member to a constant value, it can be used for adjusting the height of the support member 8.

A concrete layer 7 is formed on the support member 8 if necessary. Such a concrete layer is effective in precisely adjusting the inclination angle of the exterior panel 1. When forming the concrete layer 7, it is preferable to provide a mold material 10 in order to protect the communication portion 6.

Lamination of the exterior panel 1 on the concrete layer 7 may be generally performed via an adhesive layer such as mortar.

[0024]

According to the drainage structure of the present invention, when the exterior panel 1 is rained, rainwater flows into the drainage pipe 3 from the empty joint 1 through the communication portion 6 and into the drainage system 4. Since the joints of the exterior panel are vacant joints, and the communication part and the drainage pipe are hollow, it is possible to exert a high drainage capacity. In addition, foreign matter is less likely to be clogged in the void joint, the communication part, and the drainage pipe, and most of the accumulated foreign matter can be instantly removed by supplying pressurized water into the drainage pipe from the water supply system. is there.

[0025]

[Effect] As can be understood from the above description, the drainage structure of the present invention is formed on a structure such as an artificial ground, a basement, an underground parking lot, etc., and rainwater or the like falling on the structure is jointed. It has the feature that it can permeate and the drainage capacity of permeated rainwater etc. is extremely high.

Further, the foreign matter accumulated in the empty joint and the drainage pipe can be easily removed, and the drainage structure is extremely easy to maintain.

As a means for draining water, only the drainage pipe to be buried in the ground may be graded as described above. Therefore, there is also an advantage that the problem that the exterior panel has to be inclined due to the influence of the drainage structure does not occur.
