A cooling type permeable brick for sponge city

Abstract

The invention belongs to the field of sponge city construction, and particularly relates to a cooling type water permeable brick for a sponge city. The cooling type water permeable brick for the sponge city comprises a brick body; the interior of the brick body is provided with a cavity; a water permeable hole is formed in the lower surface of the brick body; the inside wall of the brick body is in sliding connection with a lifting plate; the density of the lifting plate is less than that of water; a through hole is formed in the lifting plate; the inner bottom surface of the brick body is rotatably connected with a water seepage plate; the water seepage plate is internall provided with a water seepage hole which corresponds to the position of the water permeable hole and communicates withthe water permeable hole; the side wall of the water seepage plate is fixedly with the inside wall of the brick body through a coil spring; the lower surface of the lifting plate is fixedly connectedwith two permanent magnetic blocks. According to the cooling type water permeable brick for the sponge city, the water storage and water seepage states can be regulated automatically according to rainfall capacity; the utilization rate of rainwater is improved; a good sponge effect is achieved; the evaporating speed of the rainwater in the brick body can be regulated according to the temperatureof a city; a good cooling effect is achieved; and moreover, the cooling speed is higher for the road surface with large population flow in the city.

Description

technical field [0001] The invention belongs to the field of sponge city construction, and in particular relates to a cooling type permeable brick for sponge city. Background technique [0002] Building a sponge city, that is, building a low-impact development rainwater system, mainly refers to the realization of a benign hydrological cycle in the city through various technical approaches such as "seepage, stagnation, storage, purification, use, and drainage", and improves the infiltration, regulation and storage of runoff rainwater. , purification, utilization and discharge capacity, maintain or restore the sponge function of the city, in the construction of the sponge city, and in the process of infiltration, storage, purification, utilization and discharge of rainwater, the cooling permeable brick plays a decisive and important role. [0003] Traditional cooling permeable bricks for sponge cities are mostly equipped with independent water storage tanks and permeable holes...
