Permeable pavement rainfall flood regulation and storage structure for sponge city

Abstract

The invention relates to a permeable pavement rainfall flood regulation and storage structure for a sponge city, and discloses a regulation and storage structure which can automatically open a drainage groove and a drainage hole through cooperation of a floating plate and a baffle plate in rainstorm weather so as to perform auxiliary drainage on a permeable pavement, temporarily improve the drainage capacity of the permeable pavement in rainstorm and avoid a pavement ponding phenomenon. The structure is characterized in that a guide block is arranged on the side wall of one side of a reservoir, a plurality of floating grooves are formed in the guide block at equal intervals, the floating grooves are communicated with the interior of the reservoir, the floating blocks are arranged in the floating grooves, one end of a connecting rod is arranged on the floating blocks, and the other end of the connecting rod vertically extends upwards to the top of the guide block; the baffle is perpendicularly arranged at the other end of the connecting rod, a drainage groove is formed in the top of the guide block, the drainage groove is an inclined groove, the baffle is correspondingly arranged onthe opening portion of the drainage groove in a covering mode, and a plurality of drainage holes are formed in the guide block.

Description

technical field [0001] The invention discloses a permeable pavement rainwater storage structure for a sponge city, which relates to a structure capable of regulating and storing permeable pavements in a sponge city, and belongs to the technical field of urban drainage. In particular, it relates to a device that can automatically open the drainage groove and the drainage hole when the floating plate and the baffle cooperate in rainy weather, thereby assisting drainage of the permeable road surface, temporarily increasing the drainage capacity of the permeable road surface during heavy rain, and avoiding the phenomenon of road accumulation The regulation and storage structure.

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The permeable pavement is a common structure commonly used in sponge cities. The current permeable pavement mainly relies on the automatic infiltration generated by the gaps in the pavement to achieve the function of permeable and flood reduction. The infiltration capacity leads to water accumulation on the permeable pavement. In the prior art, a storage tank is set under the permeable pavement to regulate and store rainwater. Although this method can ensure the continuous water seepage capacity of the permeable pavement, when the rainfall If it is too large, when the infiltration rate is exceeded, the accumulated water on the permeable pavement cannot be drained in time, resulting in the phenomenon of pavement accumulation, blocking the seepage joints of the permeable pavement, and the reaction will affect its normal infiltration capacity

[0003] Notification No. CN211689740U discloses a rainwater storage device facing permeable pavement in sponge city, including: road surface collecting pipe, water storage purification tank, groundwater supply pipeline and urban sewage connection pipeline; water storage purification tank is arranged on the outside of permeable road surface; When the adjustment and storage device encounters heavy rain, it cannot adjust the carrying capacity of the permeable pavement, and the pavement is prone to water accumulation due to insufficient carrying capacity

[0004] Notification No. CN207812613U A sponge-type rainwater drainage system, comprising: a curb stone is arranged on the permeable road surface, the curb stone separates the permeable road surface into a pedestrian road surface and a vehicle road surface, and a drainage port is opened through the side wall of the curb stone; The pavement structure of the vehicle road surface includes the first sponge prefabricated brick layer, and the first water diversion pipe is arranged inside the first sponge prefabricated brick layer; this system cannot temporarily increase the drainage capacity of the permeable road surface in the rainstorm Water accumulation problem due to mismatch of bearing capacity
