Permeable concrete pavement engineering construction method
The invention belongs to the field of road engineering, particularly relates to a permeable concrete pavement engineering construction method, and provides the following scheme aiming at the problems of poor water permeability, compression resistance and bending resistance of the existing concrete pavement: excavating and compacting a roadbed according to design requirements, paving a permeable gravel layer on the compacted roadbed, compacting again; paving molds on the two sides of the roadbed, and finally paving reinforcing ribs between the interiors of the molds and the top of a permeable gravel layer, adding an additive into the concrete, and forming a large number of bubbles in the concrete by using the additive, so that mutually communicated gaps are formed by the bubbles after paving is completed, and through dredging of the high-pressure water gun, the void ratio and the permeation coefficient of the concrete pavement are increased, the connection strength between concrete is enhanced through the permeable coagulant, and even if the concrete pavement is damaged, the concrete pavement still has high bending resistance and compression resistance.
本发明属于道路工程领域，尤其是一种透水混凝土路面工程施工方法，针对现有的混凝土路面透水性差，抗压和抗弯折能力差的问题，现提出如下方案，其包括以下步骤：按照设计要求对路基进行开挖压实，在压实的路基上铺设透水碎石层，并再次压实，然后在路基的两侧铺设模具，最后在模具的内部和透水碎石层的顶部之间铺设加强筋，通过在混凝土中加入添加剂，利用添加剂让混凝土内部形成大量的气泡，在铺设完成后这些气泡形成了相互连通的空隙，并经过高压水枪的疏通，增加了混凝土路面的空隙率和透水系数，透水凝结剂增强了混凝土之间的连接强度，即使混凝土路面受到破坏，混凝土路面依旧拥有强大的抗弯折和抗压性能。
