Embodiment 1

[0020] Embodiment 1: The device includes a rainwater collection device 2, a diversion well 4, a municipal pipe network 5, an initial rainwater abandonment well 6, a rain pond 7, an anti-seepage layer 8, a gravel layer 9, a soil layer 10, and a water stop sheet 11. Infiltration conduit 12, cover flange plate 13, butterfly valve 14, fixing bolt 15, fixing nut 16, motor 17, infiltration hole 18; several square concrete rainwater collection devices 2 are arranged so that rainfall 1 can pass through the rainwater collection device 2 can be effectively collected; the rainwater collected by the rainwater collection device 2 is transported to the diversion well 4 through the rainwater pipeline 3 for diversion, and a part of the rainwater passes through the initial rainwater abandonment well 6, and the initial rainwater with a high concentration of suspended matter is discarded. Relatively clean rainwater enters the rainwater seepage pond 7; another part of the rainwater beyond the maxi...

Abstract

The invention belongs to the technical field of municipal engineering and environment protection, and particularly relates to a dynamic permeation rain pool system based on low-influence development. When it rains, a rainwater collecting system conveys rainwater to the rain pool to be reserved; a plurality of dynamically opened and closed infiltration holes are arranged in the rain pool, and electric butterfly valves above the infiltration holes control infiltration of the rain pool. When flow enters the rain pool in rainy days, the butterfly valves are opened under set rain pool water level conditions, and the infiltration speed of the rain pool is dynamically adjusted by adjusting the difference of the rain pool water level and the underground water level, so that the rainwater rapidly infiltrates under a high water level difference. The rainwater infiltrates to the gravel layer through the infiltration holes and infiltrates slowly. After rain, the butterfly valves above the infiltration holes are closed, and the reserved rainwater serves as scenic water of the rain pool.

Description

technical field [0001] The invention belongs to the technical fields of municipal engineering and environmental protection, and in particular relates to a dynamic infiltration rainwater pond system based on low-impact development. Background technique [0002] In the process of urbanization, the increase of impermeable area and the superimposition of extreme weather conditions have caused urban waterlogging problems, which seriously threaten the safety of urban operation. The Ministry of Housing and Urban-Rural Development issued the "Technical Guidelines for Sponge City Construction-Construction of Rainwater System for Low-impact Development" issued in July 2014. It is proposed that in the future, urban construction will emphasize the main planning and design concepts of "slow drainage and slow release" and "source decentralization" control , Adopting low-impact development measures to reduce rainwater runoff from the source, the specific implementation methods include sunk...
