Rainwater back-seepage collection and storage equipment for sponge city

Abstract

The invention belongs to the related field of rainwater back seepage, and relates to rainwater back-seepage collection and storage equipment for a sponge city. The rainwater back-seepage collection and storage equipment for the sponge city comprises a shell, wherein a water inlet is fixedly formed in the upper side wall of the shell, a transverse rod which extends forwards and backwards is arranged at the water inlet and is used for blocking branches and sundries, a water storage cavity is formed in the upper side of the shell, and a sand filtering device is arranged on the upper side of the water storage cavity and is used for filtering fine sand and stones which are carried in rainwater, so that the equipment is prevented from being abraded. The rainwater back-seepage collection and storage equipment can be installed below a water outlet of an urban road surface and can be used for collecting and recycling rainwater, fine sand and stones on the road surface can be prevented from being flushed in the collecting process, the fine sand and stones are screened, water is not stored when the rainwater reaches a certain storage amount, the normal drainage effect can be recovered so as to avoid urban inland inundation when the rainfall is too large, and vortex adjusting type drainage is adopted, so that the drainage efficiency is high, and the drainage effect is good.

Description

technical field [0001] The invention belongs to the field related to rainwater reinfiltration, and in particular relates to a rainwater reinfiltration collection and storage device for a sponge city. Background technique [0002] As we all know, the current urban water shortage and the deterioration of the urban water environment, in order to maintain the harmonious development of people and water, we must pay attention to rainwater collection, use rainwater, and retain rainwater, collect rainwater and pump it out for irrigation and purification when needed However, during heavy rains, in order to avoid urban waterlogging, it is necessary to ensure normal drainage. A balance point needs to be found in the process of collecting rainwater and discharging rainwater, so that the rainwater reinfiltration equipment can always try to ensure sufficient water storage capacity. At the same time, in order to avoid For the problem of poor drainage effect during waterlogging, the drainag...

[0002] As we all know, the current urban water shortage and the deterioration of the urban water environment, in order to maintain the harmonious development of people and water, we must pay attention to rainwater collection, use rainwater, and retain rainwater, collect rainwater and pump it out for irrigation and purification when needed However, during heavy rains, in order to avoid urban waterlogging, it is necessary to ensure normal drainage. A balance point needs to be found in the process of collecting rainwater and discharging rainwater, so that the rainwater reinfiltration equipment can always try to ensure sufficient water storage capacity. At the same time, in order to avoid For the problem of poor drainage effect during waterlogging, the drainage method should be improved to make it more efficient. The existing rainwater infiltration storage equipment cannot solve the problem of more sandy soil when rainwater flows in from the ground, which will lead to rainwater collection. It gets more and more difficult later on
