Abstract

PROBLEM TO BE SOLVED: To properly infiltrate underground the rainwater fallen in an uncovered paved parking lot. SOLUTION: In the uncovered paved parking lot a water draining part is provided behind the parking wheel stop to collect rainwater and infiltrate it underground properly.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for appropriately infiltrating rainwater that has fallen into an open parking lot into a basement. 2. Description of the Related Art Conventionally, rainwater that has fallen on an uncovered pavement parking lot flows through a drainage ditch in the parking lot or directly into a road gutter or the like without penetrating underground. [0003] The present invention is based on the problem that rainwater falling on an open pavement parking lot requires a lot of expense for the treatment capacity of a public rainwater treatment facility, and also penetrates the underground. When rainwater should flow into the sea as it is, adverse effects such as a decrease in the level of groundwater have occurred. This was done to eliminate these drawbacks and to reduce flooding during heavy rains. SUMMARY OF THE INVENTION The present invention relates to a rainwater for parking lots that can be used for rainwater falling on an open pavement parking lot without using a public rainwater treatment facility and for preventing a drop in groundwater level. By providing processing equipment, it is easy to process,
The most important feature. DESCRIPTION OF THE PREFERRED EMBODIMENTS The purpose of appropriately infiltrating rainwater that has fallen into an open pavement parking lot into the underground has been realized without impairing the function of a conventional parking lot. FIG. 1 is a plan view showing a first embodiment of the equipment of the present invention, in which a drainage portion 4 is provided in a portion behind a tire stopper 3 in an open pavement parking lot. FIG. 2 is a cross-sectional view showing a second embodiment of the equipment of the present invention, showing a state where a gradient is taken from the center of the passage section 1 to the drain section 4 so that rainwater falling on the parking lot flows to the drain section. Things. FIG. 3 is a sectional view showing a third embodiment of the apparatus of the present invention, wherein a scaffold 5 is provided in a drain section 4 for walking. FIG. 4 is a sectional view showing a fourth embodiment of the apparatus of the present invention, in which a drainage section 4 is provided with a plant 6 as a planting. As described above, the parking lot rainwater treatment equipment of the present invention can treat not only rainwater in a parking lot but also rainwater in a building by drawing a rain gutter into a drainage section. It will contribute to the solution of rainwater countermeasures in urban areas, and will be effective for lowering groundwater levels. When the capacity of the drainage section can be increased, each drainage section can be used as a reservoir by connecting each drainage section with a pipe and providing an overflow pipe.
