Water permeable brick for sponge city

Abstract

The invention discloses a water permeable brick for a sponge city. The water permeable brick comprises a hollow brick body. A water inlet is formed in the upper end of the brick body in a penetratingmanner, two symmetrically formed lifting grooves are formed in the inner wall of the brick body, a partition plate leans against the bottoms of the two lifting grooves jointly, two ends of the partition plate are hermetically and slidably connected to the inner walls of the two lifting grooves, separately, a plurality of columns are fixed to the upper end of the partition plate, a chute is formedin the upper end of each column, and an air bag is fixed to the inner bottom of each chute. The water permeable brick has the advantages that rainwater entering the brick body through the water inletdoes not directly permeate into an underwater channel as being blocked by the partition plate but is stored in the brick body in advance, so that the rainwater can be stored to a certain extent, and therefore, accumulated water is supplied to air conveniently after rain stop, and the comfort level of the urban environment is improved; a water flow enters into a water outlet tank when too much accumulated water exits and is further drained to the underwater channel through a water falling pipe, so that normal drainage of the city is guaranteed.

Description

technical field [0001] The invention relates to the technical field of urban construction, in particular to a sponge city permeable brick. Background technique [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 responding to natural disasters caused by rainwater. It can also be called "water elastic city". [0003] The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, purifies water when it rains, releases the stored water and utilizes it when needed, and realizes the free migration of rainwater in the city. [0004] In order to improve the urban environment, a large number of facilities that can use rainwater are used in the construction of the city. At present, the floor tiles laid on the urban ground only have the function of beauty and water seepage, and do not ha...
