Description

[Detailed Description of the Invention] The present invention relates to a device for storing, irrigating, and infiltrating rainwater from roadside gutters to sidewalks, roadside tree belts, park green areas, etc.

Recently, as all roads and mansions in cities have been paved, the peak volume of floods has increased, groundwater shortages, and ground subsidence have occurred.
Due to the potential shortage of water resources, it has become difficult to irrigate trees in the summer and even to water to prevent dust.

As a countermeasure to this problem, there are proposals to develop highly permeable pavement or to construct the road surface itself at a higher position than the green space, so that rainwater can naturally flow down to irrigate open spaces and green spaces, but existing roads must be remodeled. The reality is that it cannot be easily put into practice.

This invention allows the surface pavement and side gutters of roads and sidewalks on which vehicles run, etc. to remain as they are, and allows rainwater collected in the gutters to easily infiltrate into the sidewalks, roadside tree belts, and nearby parks and green areas. The purpose is to provide a device.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, a rainwater collection basin 2 is provided below the bottom surface 1 of the road gutter, and a drainage pipe is installed from this basin.

The drain pipe 3 normally communicates with a drainage main pipe under the road.

A removable lid 4 made of concrete, for example, is installed on the top of the water collection mass 2.

The lid 4 is provided with a rainwater inflow hole 4a.

A ceramic pipe 5 is extended from the side of the water collection mass 2 facing the sidewalk or adjacent park green area, and a gap is left at the joint.

The opening of this ceramic pipe 5 to the water collection mass 2 is located below the opening of the drain pipe 3.

Therefore, the collected rainwater normally flows into the ceramic pipe 5.

A filter amiro is placed inside the opening of the ceramic tube 5 to prevent dirt and the like from entering the ceramic tube 5.

It is good that the filter can be removed for inspection.

As shown in FIG. 2, the area around the ceramic pipe 5 is filled with gravel 7 which has a high rainwater storage function and extends downward.

This gravel 7 communicates with the ground surface GL. In other words, there is a filler 8 such as volcanic ash or clinker between the gravel 7 and the ground surface GL.
are layered to improve the ability of rainwater to rise due to capillary force.

In addition, it is necessary to remove the lid 4 and take out the earth and sand deposited on the bottom of the water collection tank 2 from time to time.

According to this invention, there is no need to dig up all of the sidewalks and green areas, and the facility can be easily constructed. Rainwater that falls on the road can be effectively stored on the sidewalk, etc., and can be used to irrigate nearby street trees. There are advantages.

Moreover, the effects of the present invention are not only useful in flood countermeasures, but also in solving the following problems.

(b) Measures to improve water quality in combined sewer systems.

(b) Measures to initially settle sludge that has accumulated in sewer pipes in rainwater adjustment ponds.

(c) Flood countermeasures for small and medium-sized urban rivers.

2) Water resource development and ground subsidence countermeasures by replenishing groundwater.

(e) Promotion of park greening.
