Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] like figure 1 and figure 2 As shown, the present invention includes a base plate 1, a well wall 3, a cast-in-place reinforced concrete roof 4, side stones 5 and a grass planting cover plate 8.

[0012] Base plate 1 is provided with base plate filter hole 2, and base plate filter hole 2 can seep away the water in the well to avoid long-term water accumulation in the well.

[0013] The well wall 3 is built on the bottom plate 1, and the cast-in-place reinforced concrete topping 4 is built on the top of the well wall 3.

[0014] The side stone 5 is installed in the cast-in-place reinforced concrete roof 4 and has a water inlet 7 on the side stone 5, the water inlet 7 is a trapezoidal structure, the water inlet 7-1 of the water inlet 7 is connected with the road surface, and the water outlet 7- 2 is connected with the inner wall of the well wall 3, which is conducive...

Abstract

The invention discloses a low impact development based source rainwater sand setting well comprising a bottom board, a well wall, a cast-in-place reinforced concrete coping, a kerbstone and grassing cover boards. A bottom board filter hole is formed in the bottom board, the well wall is built on the bottom board, the cast-in-place reinforced concrete coping is casted above the well wall, the kerbstone is mounted in the cast-in-place reinforced concrete coping, a water inlet is formed in the kerbstone, the grassing cover boards are supported on a well top by the aid of the cast-in-place reinforced concrete coping, the kerbstone surrounds the periphery of the grassing cover board, and overflow holes are formed in the cast-in-place reinforced concrete coping and the kerbstone and below the grassing cover boards. The low impact development based source rainwater sand setting well is simple in structure, has a function of removing solid pollutants in rainwater runoff, can be widely used for solving the problem of rainwater runoff pollution, and has high social, environmental and economic benefits.

Description

technical field [0001] The invention relates to the field of drainage engineering, in particular to source rainwater grit wells based on low-impact development. Background technique [0002] Low-impact development technology is the main technology to deal with rainstorm management and non-point source pollution. It controls the runoff and pollution caused by rainstorms through scattered and small-scale sources, so that the development area is as close as possible to the natural hydrological cycle. In recent years, rainwater runoff pollution has been serious in most cities in my country, which has become the primary factor in the deterioration of urban river and lake water quality. How to reduce rainwater runoff pollution has become the primary problem to be solved in urban construction and environmental governance. Contents of the invention [0003] The purpose of the present invention is to provide a source rainwater sand settling well based on low-impact development, whi...
