Rainwater ventilation and backflow prevention infiltration facility

Abstract

The invention discloses a rainwater ventilation and backflow prevention infiltration facility. The rainwater ventilation and backflow prevention infiltration facility comprises an upstream infiltration and discharge integrated pipeline, an infiltration type inspection well and a downstream infiltration and discharge integrated pipeline which are sequentially arranged in the flowing direction. The infiltration type inspection well is internally provided with a detachable mesh cover and a ventilation pipeline. The detachable mesh cover is composed of a handle, an inserting groove and a detachable mesh cover body from top to bottom in sequence. The ventilation pipeline is provided with an air flow guide sheet, a ventilation pipeline body, a bayonet, a floating ball and a grid from top to bottom in sequence. The infiltration and discharge integrated pipeline and the infiltration type inspection well can supplement underground water, and the workload of a rainwater pipeline is reduced; a flap valve can prevent downstream rainwater from flowing back to the upstream rainwater, peculiar smell in the facility can be removed through the ventilation pipeline, and by means of the facility, the rainwater discharge managing technology which is simple in running management and low in cost is achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater drainage, in particular to a rainwater ventilation and anti-backflow infiltration facility and method. Background technique [0002] In the field of rainwater reuse and discharge, due to the shortage of water resources, residents in many places overuse groundwater as domestic water, resulting in a series of problems such as ground subsidence and land salinization. Unbearable torrential rain load, frequent flooding incidents. As a natural resource, rainwater should be used and managed properly. The currently designed rainwater infiltration and drainage integrated facilities can use infiltrated rainwater to recharge groundwater, and can also reduce the load and cost of the rainwater pipe network, but the water in the downstream permeable discharge pipe may flow back into the upstream permeable discharge pipe. In some cases, it will affect the normal work of the permeate discharge facilities, and...

Problems solved by technology

The currently designed rainwater infiltration and drainage integrated facilities can use infiltrated rainwater to recharge groundwater, and can also reduce the load and cost of the rainwater pipe network, but the water in the downstream permeable discharge pipe may flow back into the upstream permeable discharge pipe. In some cases, it will affect the normal work of the permeate discharge facilities, and may also cause cross-contamination caused by backflow
