Anti-blocking water-permeable passage

Abstract

The invention relates to the technical field of drainage, in particular to an anti-blocking water-permeable passage. The anti-blocking water-permeable passage comprises a face brick layer, a water-permeable layer, a water storage layer and a base layer which are sequentially arranged from top to bottom, wherein the face brick layer comprises solid pavement bricks which are continuously spliced andwater-permeable channels which are arranged on the solid pavement bricks; each pavement brick is provided with one water-permeable channel, and the water-permeable channels vertically run through thepavement bricks; the water-permeable layer is made of water-permeable concrete with the same aggregate grade and the porosity of about 20%; the water storage layer is formed by compacting graded broken stone particles. Filter bags capable of being replaced in time and capable of filling the whole water-permeable channels are utilized, the problem that an existing water-permeable layer is blockedand a whole pavement needs to be finished is solved, the construction cost is reduced, construction is facilitated, the service life of the pavement is prolonged, and the water seepage efficiency of the pavement is improved.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to an anti-clogging permeable walkway. Background technique [0002] With the continuous expansion of cities, not only heavy rains often cause urban waterlogging, but also rainwater cannot enter the urban groundwater circulation system well when there is a small amount of rainfall. And after the rain, there is often water on the sidewalk, and the loose floor tiles often have serious water accumulation. If you don't pay attention, you often splash water on your body. In urban construction, my country's urban street pavement is still dominated by impermeable concrete and panels. This material causes most of the rainfall to be discharged through the underground drainage system, so that the urban groundwater cannot be replenished as it should. At present, some permeable concrete pavement is used, but this kind of pavement is often blocked by about 90% after about 5 years of use, and ...

AI Technical Summary

Problems solved by technology

At present, some permeable concrete pavement is used, but this kind of pavement is often blocked by about 90% after about 5 years of use, and the water permeability efficiency is greatly reduced, so the permeable pavement cannot be vigorously promoted
