Water-permeable concrete pavement brick of automatic opening and automatic unchoking type

Abstract

The invention discloses a water-permeable concrete pavement brick of an automatic opening and automatic unchoking type, and belongs to the technical field of concrete. Through an arrangement of automatic opening combined bulb tubes, when water is accumulated on the surface of a water-permeable concrete brick body, normally-closed elastic seams can be automatically opened, accumulated water can be drained sequentially through the normally-closed elastic seams, supporting spherical shells and water-permeable pipes, and permeability and drainage efficiency of the pavement brick can be greatly improved; the normally-closed elastic seams are in a closed state when water drainage is not necessary, dust and impurities can be effectively prevented from entering the normally-closed elastic seams, and the water-permeable pipe is not prone to be blocked; in addition, with automatic combined ball rods, when the water-permeable pipes are blocked in a water drainage process, hole plugs can automatically plug water-permeable holes, gas-producing material balls can be automatically squeezed and fall into a gas-producing solution, and the gas-producing material balls and the gas-producing solution react to generate a large amount of carbon dioxide which continuously flows into the water-permeable pipes, so that a downward thrust is produced to unchoke the water-permeable pipes, and the water-permeable pipes can be automatically unchoked.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a self-opening and self-passing permeable concrete pavement brick. Background technique [0002] Permeable concrete, also known as porous concrete, sand-free concrete, and permeable floor, is a kind of porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate and is covered by coarse aggregate. Thin layers of cement paste are bonded to each other to form a honeycomb structure with uniform distribution of pores, so it has the characteristics of air permeability, water permeability and light weight. [0003] In the past, pavement bricks on urban roads were generally not permeable. Impervious pavement bricks would not only block the infiltration of natural precipitation, resulting in lower and lower urban groundwater levels, but also affect the drainage of roads, causing water accumulation on roads. Therefore, with the development o...

Problems solved by technology

[0004] However, the permeable concrete pavement bricks in the prior art can only rely on their own water permeability for drainage. It can play a limited role and is easy to clog. Once clogged, it will not only further reduce the drainage efficiency, but also make it difficult to dredge
