Flood prevention and reduction facility for landscape box

Abstract

The invention provides a flood prevention and reduction facility for a landscape box. The invention belongs to the technical field of sponge cities, a pedestrian street, permeable gravels and a roadbed are arranged around a flood-proof drainage landscape box system device from top to bottom, the roadbed is arranged below the flood-proof drainage landscape box system device, an outer expansion water tank is arranged on the outermost layer in the structure of the flood-proof drainage landscape box system device, a clamping groove is formed in the inner side of the side wall of the external expansion water tank, an annular water-permeable bearing plate is arranged in the structure of the flood-proof drainage landscape box system device, the four edges of the annular water-permeable bearing plate are clamped in the clamping groove, a plurality of drainage water-permeable holes are formed in the annular water-permeable bearing plate, a landscape box is arranged in the structure of the flood-proof drainage landscape box system device, the landscape box is located on the annular water-permeable bearing plate. The facility has the advantages that the phenomena of rainwater resource waste, urban waterlogging and the like can be effectively solved while greening is conducted, good economic benefits and social benefits are achieved, and the important concept that landscape construction is urban greening and urban planning is catered.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to a landscape box flood prevention and flood reduction facility. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, absorb water, store water, infiltrate water, filter water, purify water, "release" the stored water and use it when needed. With the development of urbanization, the area of ​​impermeable ground is increasing rapidly, so it is necessary to develop The self-sufficient water supply landscaping and greening system that can make up for these deficiencies can collect rainwater, use rainwater to conserve lawns, improve the u...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a landscape box flood prevention and flood reduction facility, which can effectively solve the waste of rainwater resources and urban waterlogging while greening. It mainly solves the problem of pavement area water. In the present invention, adjusting the structural setting in the waste flow chamber will play a more appropriate and efficient discharge scheme according to the change of rain conditions, that is, the accumulation and infiltration of rainwater on the pedestrian street and the cultivation soil.
