A multi-functional assembled rainwater outlet and its construction method

Abstract

The invention discloses a multifunctional assembled gully and a construction method thereof. The multifunctional assembled gully includes a rainwater grate, a deflector, a filtering device, a rainwater well and a seepage well; structure, a floating block is set at the bottom of the rainwater well, and water outlets, first drainage outlets and second drainage outlets with different heights are arranged on the side walls of the rainwater well, and the water outlets are connected to the municipal pipe network through the outlet pipe; the infiltration well Gravel masonry is used, and the rainwater well and floating blocks are placed in the infiltration well as a whole; the filter device is installed in the rainwater well, and the rainwater grate is covered on the wellhead of the infiltration well, and one end of the deflector is hinged with the bottom edge of the rainwater grate to guide the flow The other end of the plate extends into the stormwater well and leads to the water inlet of the filter unit. The stormwater outlet in this case has a simple structure and quick and easy construction. It can be installed in sponge facilities such as sunken green spaces and biological retention ponds, and can also be installed on municipal roads to regulate road rainwater.

Description

technical field [0001] The invention relates to a multifunctional assembled gully and a construction method thereof, belonging to the sponge city construction technology. Background technique [0002] my country is a country seriously short of water resources. Among the 668 cities in the country, more than 400 are short of water, of which 110 are seriously short of water. However, at the same time, rainwater resources are severely wasted. The rainwater is concentrated and discharged through the drainage pipe network, which puts a lot of pressure on the municipal rainwater pipes, and urban waterlogging occurs from time to time. Many cities are faced with the contradiction of waterlogging every time it rains, and the shortage of water resources at the same time. [0003] The gully is a facility for the pipeline drainage system to collect surface water. The traditional gully cannot intercept pollutants in the water, and with the change of the urban ecological environment, the ...

AI Technical Summary

Problems solved by technology

[0003] The gully is a facility for the pipeline drainage system to collect surface water. The traditional gully cannot intercept the pollutants in the water, and with the change of the urban ecological environment, the living environment of some mosquitoes has also undergone significant changes. This environmental change also It is easy to cause bad smell in the rainwater outlet, flies, mosquitoes and other flying insects and reptiles come out of the rainwater outlet, and in some places, there are constant rodents, which seriously affect the urban living environment

When the gully is constructed according to the traditional construction technology, there is a shortcoming of being affected by space, and the quality of the whole process is not easy to control; and the traditional gully cannot be prefabricated in advance, which will also affect the construction period
