Description

Concave formula greenery patches infiltration drainage device

Technical Field

The utility model relates to a greenery patches drainage device technical field, in particular to recessed greenery patches infiltration drainage device.

Background

The sponge city is a new generation of urban rainfall flood management concept, and means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be also called as a water elasticity city. The international generic term is "low impact development storm water system construction". When raining, the utility model absorbs water, stores water, seeps water and purifies water, and when needed, the stored water is released and utilized. The sponge city construction combines natural approaches and artificial measures, realizes the accumulation, permeation and purification of rainwater in urban areas to the maximum extent on the premise of ensuring the safety of urban drainage and waterlogging prevention, and promotes the utilization of rainwater resources and ecological environment protection. In the sponge city, the drainage structure is one of the most important structures, the infiltration of rainwater, filtering capability and drainage structure have very big relation, and drainage structure has directly influenced the function in sponge city.

With the continuous promotion of the construction process of the national sponge cities, the construction of the sponge cities in various regions is also carried out in a fierce and vigorous way, and the green lands with certain storage and purification capacities, such as the sunken green lands, are widely applied.

The storage capacity (water storage capacity) of the concave green land is determined by the area of the concave green land and the effective water storage depth, for general projects, the area of the concave green land is determined, and the area of the concave green land is more accurate under the condition that the land of individual project is tense, under the condition, if the small water storage depth is designed, the storage capacity is too small, and the requirement of the sponge city on the annual runoff total amount control rate is often difficult to meet; if a larger water storage depth is designed, the water accumulation time is too long, so that the water is difficult to drain or the water drainage is very slow (the underground water is saturated, the top plate of the underground building below the water is not permeable and the like), so that the vegetation is soaked in the water for a long time and rotten and withered, and the vegetation is damaged and unreliably lost.

The existing water seepage and drainage device has a complex structure and high production cost, and is not beneficial to large-scale utilization; the existing water seepage and drainage device has limited water seepage or drainage capacity and poor water seepage and drainage capacity, is not beneficial to water seepage and drainage in multiple rainy seasons of southern cities, and is easy to cause surface water accumulation.
