Sponge city permeation, retention, storage, purification, utilization and water drainage combined system

Abstract

The invention provides a sponge city permeation, retention, storage, purification, utilization and water drainage combined system, belonging to city environmentally protective facilities. A water storage device composed of a barrel, gravel stratum upper and lower permeation layers, coarse sand upper and lower retention layers and a fine sand purification layer is assembled below a pavement water-permeable device, a water purification device, a rear water outlet pipe and a submerged pump are arranged in a well pipe, the submerged pump communicates with the rear water outlet pipe, the water purification device is composed of a PVC pipe or a steel pipe, a ceramsite gravel-lined layer, a reinforcing steel bar barrel, a blocking bottom board and an upper cover plate, a water guide pipe communicates the water storage device and a water storage pond, the PVC pipe or the steel pipe communicates the water storage pond and the water purification device, and a front water outlet pipe is assembled on the water storage pond. The system is novel, reasonable and simple in structure, reliable in use, and good in permeability and drainability, can resist corrosion, and is long in service life, and thus a technical support is provided for the sponge city construction.

Description

technical field [0001] The invention belongs to urban construction environmental protection facilities, and mainly relates to a combined system of seepage, stagnation, storage, purification, utilization and drainage in a sponge city. Background technique [0002] Sponge city construction is an important part of my country's ecological civilization construction, and one of the important measures is to increase the infiltration and retention of surface water. How to increase the infiltration and retention of surface water without polluting the original groundwater has been paid attention to. At present, gravel piles and underground infiltration wells are one of the main devices to increase the infiltration and retention of surface water. However, the former has the disadvantages of small infiltration capacity, small storage capacity, and insignificant drainage effect; although the latter increases the infiltration amount of surface water, the water purification effect is poor...

Problems solved by technology

However, the former has the disadvantages of small infiltration capacity, small storage capacity, and insignificant drainage effect; although the latter increases the infiltration amount of surface water, the water purification effect is poor, and there is a potential crisis of groundwater pollution, and underground seepage Wells are prone to clogging and have a limited lifespan
