JPH0724466Y2 - U-shaped groove made of synthetic resin - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a synthetic resin U-shaped groove, especially a synthetic resin used for collecting surface water when it rains on a golf course or a residential land development site. It relates to a U-shaped groove.

[Conventional technology]

Conventionally, in places with ups and downs such as golf courses and residential land development sites, in order to prevent the outflow of sediment and the damage to the lawn due to running water during rainfall, as shown in Fig. 3, inside and outside corrugated pipes are used. A U-shaped groove made of a synthetic resin, which is a semicircle gutter-shaped by dividing a tube main body having a bellows-shaped uneven portion on the wall surface, was buried along the ground surface of the slope.

[Problems to be solved by the invention]

However, the above-mentioned semi-circle gutter-shaped U-shaped groove made of synthetic resin is complicated in structure because it lacks in shape retention and flexibility, and is buried especially along a complicated slope such as a golf course. It required considerable skill to do so.

[Means for solving problems]

The present invention was devised to eliminate the above-mentioned drawbacks of the conventional products, and it is a problem that a water flow hole is formed by cutting the concave wall surface in the upper half of the pipe body having bellows-shaped irregularities on the inner and outer wall surfaces. I solved the point.

The bellows-shaped irregularities of the pipe body may be spiral or independent ring-shaped, and the size of the water flow hole is approximately the same as the width of the recess and the length of the pipe is small. It is preferable that the shape of the main body is inferior arc, which is about 1/3 of the arc.

〔Example〕

1 is a front view showing an embodiment of a synthetic resin U-shaped groove of the present invention, wherein polyethylene is used as a material to form spirals on inner and outer wall surfaces. In the upper half part of the pipe body A provided with the bellows-like irregularities 1 and 2,
By cutting off the wall surface of each recess 1, a water flow hole 3 having an opening width substantially equal to the width of the recess 1 and having a length of about 1/3 of the arc of the pipe body A is formed. Is.

[Effect of device]

Since the synthetic resin U-shaped groove of the present invention has the above-mentioned structure, when it is used, it is buried along the slope so that the end face of the opening of the water flow hole is substantially flush with the ground surface as shown in FIG. It is what is done.

The synthetic resin U-shaped groove of the present invention is formed by cutting the recess wall surface to form a water flow hole in the upper half of the tube body having bellows-like irregularities on the inner and outer wall surfaces, and the whole is substantially circular. Since it is made of a material such as a U-shaped groove that does not expand during construction or changes over time, it can be bent almost in the same way as a circular pipe, further improving workability and adding the length of the opening. By making the length of the arc of the pipe body inferior to that of the arc of the main body, the embedding portion becomes the opposite arc, and therefore the lift of the U-shaped groove is also reduced.
