Spongy rainwater collection and utilization system for school built on natural mountain

Abstract

The invention discloses a spongy rainwater collection and utilization system for a school built on a natural mountain, and belongs to the field of rainwater collection and utilization. The system involves a greening area rainwater collection device and a track field rainwater collection device; the greening area rainwater collection device comprises a vegetation layer arranged on the surface of agreening area, a fine sand layer arranged below the vegetation layer, a gravel layer A arranged below the fine sand layer, and a water storage tank A and a water purification and filter tank A both arranged below the gravel layer A; and the track field rainwater collection and utilization device comprises a buffer layer arranged on the surface, a bottom sealing layer arranged below the buffer layer, a gravel layer B arranged below the bottom sealing layer, a base layer arranged below the gravel layer B, and a water storage tank B and a water purification and filter tank B arranged below the base layer. The system solves the problem of insufficient water supply caused by large altitude drop.

Description

technical field [0001] The invention relates to a spongy rainwater collection and utilization system used in natural mountain schools, belonging to the field of rainwater collection and utilization. Background technique [0002] At present, China is facing various problems such as water crisis, water resource shortage, water pollution, flood, urban waterlogging, and groundwater level drop. This is a systemic and comprehensive problem. The proposal of the "sponge city" theory is based on my country's water regime characteristics and water problems. Some cities are affected by heavy rain, and floods, waterlogging, and tidal disasters occur from time to time. Although the rivers in the territory have been treated with high standards, there are still flood control safety accidents in some areas. For rainwater, increase the storage of rainwater by laying out sponge facilities, reduce the amount of rainwater discharged into the rainwater pipe network, and reduce the occurrence of...
