A sponge-type gully construction structure

Abstract

The invention discloses a sponge type gutter inlet building structure which comprises a vertical grate type grate, an upper water discharge passage, a plurality of sponge water discharge cabins, a main water discharge passage and a fine sieve screen, wherein the upper water discharge passage is connected with the grate; the sponge water discharge cabins are connected with the bottom of the upper water discharge passage; the main water discharge passage is connected with the sponge water discharge cabins; the fine sieve screen is arranged in the upper water discharge passage and is positioned at the back part of the grate and the sponge water discharge cabins; the plurality of water sponge water discharge cabins are installed; and the upper water discharge passage and the main water discharge passage are connected, and the connecting position is positioned at the back part of the fine sieve screen. The technical problems that in the prior art, the water discharge quantity of a sewer cannot be controlled according to the rainfall capacity, and the rainwater cannot be controlled to pass a filter device with proper sieve holes are solved.

Description

technical field [0001] The invention relates to a drainage system, in particular to a construction structure of a sponge-type gully. Background technique [0002] The rainwater outlet refers to the facility for the pipeline drainage system to collect surface water. It is a structure that collects rainwater on the rainwater pipe or combined pipe. The channel directly sent to the urban river and lake water system is not only the bottleneck of the urban drainage system to collect rainwater runoff, but also the primary channel for urban non-point source pollutants to enter the water environment. It not only drains water for urban roads, but also replenishes water for urban water bodies. There are two main types of rainwater outlets: flat grate type and vertical grate type. The flat grate type water flow is smooth, but it is easy to be blocked by sundries such as branches during heavy rain, which affects the water collection capacity. The vertical grate type is not easy to blo...
