Sand-based water permeable brick with filtering function

Abstract

The invention relates to the technical field of building materials, and discloses a sand-based water permeable brick with a filtering function, which comprises a brick body, and the brick body is formed by bonding quartz sand, an opening is formed in a part of the top surface of the brick body, a plurality of first water permeable holes penetrating to the bottom surface of the brick body are formed in the brick body from the opening, and a filter screen for covering each first water permeable hole is inserted into the top surface of the brick body; a push-pull plate is inserted into the top surface of the brick body in a sliding manner, is formed by molding concrete, and is configured to be in friction contact with the filter screen. The filter screen covering the first water permeable holes is inserted into the top face of the brick body, rainwater and the like entering the first water permeable holes can be filtered through the filter screen, filtered objects on the filter screen canbe pushed away through the sliding push-pull plate, and therefore the filter screen can be cleaned, and it is guaranteed that the filter screen can be continuously used.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sand-based permeable brick with a filtering function. Background technique [0002] In recent years, severe urban waterlogging caused by heavy rains has plagued people everywhere. Sponge cities have become an important symbol of the transformation of urban development concepts and construction methods. More than 130 cities across the country have formulated sponge city construction plans. Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, water supply, drainage and other water recycling links should be coordinated, and its complexity and long-term nature should be considered. To build a sponge city, an effective way...

Problems solved by technology

At present, the leaking outlet of underground drainage pipes generally adopts permeable floor tiles with long strips of pores. Although this kind of permeable floor tiles can drain a large amount of rainwater into underground drainage pipes, they cannot filter small impurities in rainwater, etc. , it is easy to block the underground drainage pipes; in addition, when too much water in the underground drainage pipes seeps out, the accumulated water will overflow from the permeable floor tiles, and the accumulated water is generally dirty and smelly, thus affecting the road environment
