Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a surface water drainage device used for collecting surface water during and after rain on a ground such as a fairway of a golf course. It is related to.

[Conventional technology]

Conventionally, as this type of surface water drainage device, a culvert drainage pipe (see Japanese Utility Model Publication No. 47-4187) in which a suction pipe is buried in the ground so that surface water penetrates underground using negative pressure is used. It had been.

[Problems to be solved by the invention]

However, the above-mentioned surface water drainage device is effective in the case of light rain, but has its own limit when rainwater stays on the surface like heavy rain, and it stands up from the culvert drainage pipe on the ground surface. If the hydrophobic filter at the opening of the rising riser is installed flush with the ground surface, it will not be able to withstand long-term use because it will be clogged with dust unlike air holes in the ground. There was a problem. Further, simply increasing the size of the opening causes a problem in that earth and sand are mixed into the culvert drainage pipe and the pipe itself is clogged.

[Means for Solving the Problems] The present invention has been devised in order to solve the above-mentioned drawbacks of the conventional product, and has a culvert drain pipe buried in the ground on a fairway or the like of a golf course, and the culvert drainage. In a surface water drainage device such as a ground having a plurality of rising pipes erected at appropriate intervals from a pipe toward the ground surface, an opening provided above the rising pipe is installed substantially flush with the ground surface. In addition, the problem is solved by detachably attaching a lid with a perforated plate to the opening.

That is, by providing a lid with a perforated plate in the opening, an effect of preventing clogging with dust is provided, and by making the lid with a perforated plate detachable, water is injected from the opening under pressure so that the culvert can be closed. An effect that the inside of the drain pipe can be cleaned is provided.

〔Example〕

FIG. 1 is a partially enlarged cross-sectional view showing one embodiment of a surface water drainage device such as a ground according to the present invention. FIG. In the figure, reference numeral 1 denotes a culvert drain pipe buried at a predetermined interval in a ground A such as a fairway of a golf course, and reference numeral 2 denotes a culvert drain pipe 1 which is set up to communicate with each other from the culvert drain pipe 1 toward the ground surface. A riser pipe, a plurality of which are erected at appropriate intervals so that the opening is substantially flush with the ground surface; The cover body is formed so that it can be easily removed by screwing or fitting.

As the culvert drain pipe 1, it is preferable to use a water absorption pipe formed by piercing a water absorption hole 4 in a wall surface of a synthetic resin pipe made of vinyl chloride or polyethylene.
A synthetic resin short tube as shown in the figure is used, and a mesh-shaped lid having a size that does not allow a golf ball to be used is used as the perforated lid 3.

[Effect of the invention]

As is clear from the above, the surface water drainage device such as the ground of the present invention has a plurality of riser pipes communicating with the culvert drainage device, and the erecting pipes are erected so that the openings thereof are substantially flush with the ground surface.
A lid with a plate is provided at the opening, which has the effect of preventing clogging with dust. By making the lid with the plate detachable, water is injected from the opening under pressure to drain the culvert. This has the effect of cleaning the inside of the pipe, and furthermore, surface water that stays in the ground, such as the fairway of a golf course, is led to the culvert drainage pipe from the opening of the riser pipe, and rainwater that permeates the ground is used as the culvert drainage pipe. The use of the water-absorbing pipe has the effect of being drained from the water-absorbing hole and drying quickly.
