Description

Sponge city rainwater garden self-loopa oozes holds structure

Technical Field

The utility model relates to a circulation is oozed and is held the structure, concretely relates to sponge city rainwater garden self-loopa oozes and holds the structure belongs to urban drainage retaining technical field.

Background

The sponge city changes the traditional rainwater treatment mode mainly including building large pipes and fast draining in the city by using a low-influence development concept, drains water by virtue of natural force, disperses the source and slowly drains and releases rainwater, collects, stores, permeates and purifies the rainwater nearby, ensures that the city breathes and receives smoothly like ecological sponge, and realizes the natural migration of the rainwater in the city. Roads are an important source of surface runoff. Rainwater flows into the green land with the concave shape of the isolation belt from the road along the opening, and the filtering layer formed by pebbles, slag and sand purifies and stores the rainwater like a sponge. The redundant rainwater passes through the rainwater grate higher than the green land, most of the redundant rainwater flows into the nearby rapid infiltration well, and the rest part of the redundant rainwater overflows to the storage tank. All roads are used for laterally collecting and infiltrating rainwater through the longitudinal concave green land and irrigating green plants. The simple accumulation device for gravel and sandy soil is arranged at a certain distance or the continuous water storage filtering ditch is longitudinally arranged along the road, so that rainwater on the road surface of the road is collected, purified and accumulated in a stagnation way. The surplus rainwater firstly overflows to nearby greenbelts to infiltrate, and when the rainwater meets heavy rainstorm with large rainfall and short duration, the surplus rainwater overflows and is drained to a city drainage main pipe network through the rainwater in the road rainwater well. More than 70% of rainwater on the road surface can be collected and utilized basically. The self-circulation seepage storage is an essential component in a sponge city, rainwater is filtered and stored, and plants are irrigated regularly and quantitatively through an atomizing nozzle; however, the existing self-circulation infiltration storage has the following defects: 1) the ground surface is usually provided with only part of the filtering water storage devices, so that most of rainwater is wasted; 2) if the number of the water permeating and storing devices below the ground surface is large, the hollow span below the ground surface is large, and the problem of green belt collapse is easy to occur; 3) after the filter layer is used for a long time, more silt is inevitably retained to cause blockage, so that the filtering failure is caused.

Therefore, further improvements are awaited.
