Description

[Detailed description of the invention] The present invention forms a mesh part 2 integrally with the drainage ditch main body 1 at the upper part of the drainage ditch main body 1 exposed to the ground surface, and the mesh part 2 exposed to the ground surface is A blinding part 3 exposed to the ground surface is provided on both sides, and the blinding part 3 is inclined so that the side closer to the mesh part 2 is higher, the outer end of the mesh part 2 is formed into a blinding part 3.
while making it slightly higher than the end opposite to the mesh part 2,
This relates to a resin drainage ditch that is integrally formed with an outwardly projecting lifting prevention part on the side wall of the drainage ditch body, and its purpose is to prevent earth and sand from flowing into the interior. There is a drainage ditch that can be provided.

The present invention will be explained in detail below using examples.

1 in the figure is a drainage ditch main body, and a mesh part 2 is formed integrally with the drainage ditch main body 1 at the upper part exposed to the ground surface.
Further, blind portions 3 are provided along the entire length of both sides of the mesh portion 2 that are exposed to the ground surface, and a drainage ditch A is formed.

The drain A having such a structure is formed by extruding a resin.

When constructing the drain A, the drain A is used by being buried underground, and in this case, the mesh portion 2 and the closed portion 3 are exposed on the ground surface.

Here, the blinding part 3 is inclined so that it becomes higher toward the mesh part 2 as shown in the figure, and as a result, as shown in the figure, the outer end of the mesh part 2 or the mesh part of the blinding part 3 It is slightly higher than the end opposite to 2.

Drainage such as rainwater flows from the ground surface B through the mesh part 2 into the drainage ditch A and is drained away, but at this time, it is drained by the sloped closing parts 3 on both sides of the mesh part 2. It is designed to prevent earth and sand from flowing from the ground surface B to the mesh part 2.

Here, the blinding part 3 is inclined so that it becomes higher toward the mesh part 2, but drainage ditches are generally provided at a lower position on the ground, and the ground surface B is inclined so that it becomes lower as it approaches the drainage ditch A. Because of this, the top of the drain is covered with a large amount of water.

Even if the outer end of the mesh part 2 is slightly higher than the end of the closing part 3 on the opposite side from the mesh part 2, there is no problem in draining water from the ground surface B into the drain A, Ground surface B
A small amount of water remains at the end of the drainage ditch A side and the blind part 3 without being drained into the drainage ditch A, but since this remaining water is a small amount, it is assumed that it has seeped into the ground from the ground surface B. It disappears in a short time due to evaporation.

Furthermore, even if earth pressure is applied to the side wall and the side wall bends inward, the drainage ditch is constructed by sloping the blind part so that it becomes higher toward the mesh part, so that the outer end of the mesh part is connected to the mesh part of the blind part. Since it is slightly higher than the end opposite to the shaped part, the mesh part of the drain is always curved upward, and the cross-sectional area of the drain is not narrowed.

A lifting prevention protrusion 4 is provided on the outer wall of the drain main body 1.

Here, if the lower part of the drain main body 1 is formed into a V-shape as shown in the figure, it is possible to further prevent the water from rising up from below due to water seeping into the ground.

Further, if the drain main body 1 is semicircular, it will easily rotate if one end of the drain main body 1 is stepped on, but if it is formed into a non-semicircular shape, it will not rotate even if one end is stepped on.

In the present invention, as described above, the upper part of the drain body that is exposed to the ground is formed with a mesh part integrally with the drain main body, so the mesh part prevents dirt, stones, etc. from getting inside. It has the advantage that it does not flow into the ground and does not get clogged.Moreover, it has the advantage that blinding parts exposed to the ground surface are provided on both sides of the mesh part exposed to the ground surface, and the blinding parts are sloped so that the side of the mesh part is higher. Therefore, when rainwater, etc. is drained from the mesh part into the drain main body, the sloped closing part 1 can prevent earth and sand on the ground surface from flowing into the mesh part together with the rainwater, etc.

In other words, even if the earth and sand on the ground surface try to flow into the mesh part along with rainwater, etc., the earth and sand will not be located on the surface of the rainwater, but will flow at the bottom (i.e., above the blind part), and therefore, due to the sloped blind part. Earth and sand are prevented from flowing into the mesh portion, and only rainwater located above the dirt flows into the mesh portion.

Although the blinding part is inclined so that it becomes higher toward the mesh part, the outer end of the mesh part is only slightly higher than the end of the blinding part on the opposite side to the mesh part. In addition, the ground surface is generally sloped so that the drain side is lower, so there is almost no problem with drainage from the ground surface into the drain. A small amount of water remains in the closed area without being drained into the drain, but this remaining water is a small amount and will disappear in a short time by seeping from the ground surface into the ground and evaporating. be.

Furthermore, since the mesh portion and the drain main body are integrated, there is an advantage that the upper part of the drain main body can be prevented from expanding or contracting.
