Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temporary drainage channel formed by using a hollow plastic sheet material.

[0002]

[Prior Art]

 Conventionally, as a temporary drainage channel for simply flowing water, non-woven fabric was laid along the inner surface of the groove that was dug in the ground beforehand, and asphalt emulsion was sprayed on the surface to prevent water leakage. A temporary drainage channel or a trench that has been dug down is simply laid with a coated fabric called open sheet or blue sheet on the inner surface.

[0003]

[Problems to be solved by the device]

 By the way, in the conventional temporary drainage using asphalt, not only the width and depth of the groove to be created in advance or the dimensions of the setting line must be accurately taken in detail, but also the inner surface of the groove must be finished to a solid flat surface. Therefore, it took a lot of time and effort to form the groove. In addition, after laying the non-woven fabric, the asphalt emulsion is sprayed, which requires a great deal of work. In addition, since water leakage is prevented by spraying asphalt emulsion, uneven spraying causes water to pass through, resulting in water leakage, which prevents it from functioning as a drainage channel. Furthermore, when the temporary drainage canal is completed and the restoration is restored to its original state, not only is it difficult to remove the non-woven fabric with asphalt emulsion, but the non-woven fabric that has been removed cannot be regenerated and becomes bulky waste. Is. On the other hand, the temporary drainage canal using coated fabric is easy to lay, but it is easily damaged and damaged, resulting in poor durability.

The present invention has been made in the background of such a conventional technique. The groove to be dug in order to be laid is not required to have a very accurate size, and the construction is not troublesome. The purpose is to obtain a temporary drainage channel that not only shortens the construction period but also is easy to work with, does not worry about water leakage, is easy to remove and can be regenerated, and has excellent shape retention and durability. To do.

[0005]

[Means for Solving the Problems]

 The present invention is a hollow sheet material that is exposed on the ground surface by laying a plastic hollow sheet material in which ruled lines are pressed and formed in a grid pattern by a hot press along a groove that is previously dug in the ground. It is intended to provide a temporary drainage channel characterized in that both ends of it are buried and fixed in the soil.

[0006]

[Action]

 By doing so, surface water due to rain etc. is collected in the temporary drainage channel of the hollow plastic sheet material, and is drained to drainage sites such as rivers without fear of leakage through this temporary drainage channel. That is, according to the present invention, not only the laying but also the removal can be performed extremely quickly and easily, and the recycling can be performed without generating waste materials.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the temporary drainage channel 01 of the present invention is a drainage channel body that uses polypropylene plastic hollow sheet material 05 as a material in a groove 12 that is dug down with a drainage gradient on the ground surface 11. 02 is laid. As shown in FIG. 2, for example, this plastic hollow sheet material 05 has a structure similar to that of a danboule material, and is composed of side plates 51, 51 on both sides and a reinforcing plate 52 for reinforcing the hollow portion, and The ruled lines 53 are pressed and formed in a grid pattern by a heat press or the like at arbitrary intervals. Here, in this plastic hollow sheet material 05, the thickness t is 2 to 30 mm, the side plate 51 has a thickness t ₁ of 0.2 to 5 mm, and the reinforcing plate 52 has a thickness t ₂ of 0.2 to 5 mm. The distance L between the reinforcing plates 52 is preferably in the range of 2 to 30 mm. As described above, the plastic hollow sheet material 05 has a double structure, and thus has excellent durability against tearing, and since the grid-shaped ruled lines 53 are formed by pressing, the shape retention property is excellent. ing. The groove 12 has a width W and a depth D selected with a slight margin with respect to the cross-sectional area selected corresponding to the predicted flow-through amount, and the shallow excavation parallel to both sides of the drainage groove 13. The fixing grooves 14 and 14 are formed.

As shown in FIG. 1, the drainage channel main body 02 includes a running water portion 03 and a fixed portion 04. The running water portion 03 is formed by bending a central portion of the drainage channel body 02 into a square U-shape to form a bottom portion 31 and left and right side portions 32. The fixed portion 04 is composed of a horizontal portion 41 in which both end portions of the drainage channel main body 02 are bent outward at a substantially right angle, and a fixed portion 42 in which an end edge is further bent downward by about 45 degrees.

Therefore, in order to lay the drainage channel main body 02, the flowing water portion 03 is installed in the drainage groove 13, the gap between the two is filled with mud to adjust the shape of the flowing water portion 03, and the fixing portion 04 is horizontally leveled. The portion 41 is placed on the ground surface 11, the fixing portion 42 is installed in the fixing groove 14, and then the mud is placed so that it is flush with the ground surface 11 and the fixing portion 42 is fixed to fix the fixing portion 42. The main body 02 is set in a solid state, and since water does not enter the back surface of the drainage channel main body 02, a strong laying is completed.

Since the hollow sheet material 05 can be obtained as a long strip-shaped material, the temporary drainage channel 01 does not usually need to be spliced, but if a splicing is required depending on the topography, the upstream side It suffices to insert the end portion of the above into the downstream base end portion and connect it. However, if necessary, the connecting portion may be welded by hot pressing or the like or may be joined by using an adhesive. Further, when the flowing water channel is required to be curved by the setting line, it can be dealt with by interposing the short hollow sheet material 05 by the above-mentioned connecting method.

The embodiment of the present invention has been described above with reference to the drawings. However, the present invention is not limited to this embodiment, and the present invention can be made even if there is a design change or the like without departing from the scope of the invention. Included in the device. For example, although polypropylene is used as the material of the hollow sheet material 05 in the above-mentioned embodiment, any general-purpose plastic having good corrosion and weather resistance can be applied. Further, although the cross-sectional shape of the drainage channel is a square U shape, it may be a shape using a part of a V shape or a polygon.

Further, in the embodiment of the present invention, the hollow sheet material 05 shown in FIGS. 1 and 2 was described, but the present invention is not limited to this shape, and another hollow sheet material 06 as shown in FIG. 3 is used. It may be. In this hollow sheet material 06, a melted first film 62 and a melted second film 63 are placed on both sides of a cylindrically embossed film 61 and heat-sealed to separate air into a cylinder. It is a three-layer structure consisting of a space and a continuous space through which air passes, and it is a lightweight and rigid hollow laminated plate. The hollow sheet material 06 may be composed only of the film 61 and the first film 62 that are embossed in a cylindrical shape, or may be composed only of the film 61 and the second film 63. ..

[Effect of the device]

 As described above, according to the present invention, a hollow plastic sheet having ruled lines pressed in a grid pattern by a heat press is laid along a groove that has been dug in the ground in advance and is exposed on the ground surface. Since both ends of the hollow sheet material are buried and fixed in the soil and laid, the groove for laying the temporary drainage channel does not require so precise dimensions, so excavation and shaping of the groove are extremely easy. Yes, all you have to do is set the drainage channel body in the groove. In addition, the hollow sheet material is not only firmly fixed by the both ends, but also water does not penetrate into the back surface thereof. With these, many effects can be obtained in shortening the construction period and reducing the construction cost. Furthermore, since it uses plastic, it has many advantages such as being less likely to be damaged, causing no problems such as water leakage, being easy to remove, and being able to be recycled without producing waste. There is. Furthermore, since it has a hollow structure, it is not easily broken and has excellent durability, and since the ruled lines are pressed and formed in a lattice pattern on the sheet, it has excellent shape retention.
