Abstract

The invention discloses a rapid construction method for single-layer pervious concrete. According to the rapid construction method adopting a commercial concrete production line, a pervious concrete mixture is transported to a construction site by a dump car. Rapid construction work of the single-layer pervious concrete is completed by combination of a paver, a road roller and a polishing machine.With sufficient utilization of existing available devices, not only is the problem of slow progress of manual construction of pervious concrete engineering solved, but also the harmful environmentalproblems of dust, noise and the like caused by stirring on site are effectively solved. The pervious concrete is low in cost, rapid in construction progress, high in mechanical strength and suitable for places such as sidewalks, light pavements, squares and the like.

Description

technical field [0001] The invention belongs to the field of concrete processing, and in particular relates to a rapid construction method for single-layer permeable concrete. Background technique [0002] With the continuous improvement of the level of urbanization, urban roads, squares and outdoor leisure places have increased a lot, and more and more urban roads are covered with dense and impermeable concrete, which leads to the inability of rainwater to penetrate into the ground in time and affects the quality of urban groundwater. , and caused the farce of "city view of the sea". Permeable concrete is a new type of concrete born to make up for the impermeability of ordinary concrete. Through the combination with urban greening system and drainage system, it can efficiently solve the above problems. [0003] How to provide a fast and environmentally friendly production method for permeable concrete has become one of the problems to be solved urgently in the prior art. ...
