Construction method of polyurethane gravel permeable pavement
The invention discloses a polyurethane gravel permeable pavement construction method, which comprises the following steps: early-stage preparation, gravel material and polyurethane adhesive preparation, mixture preparation, material spreading, joint cutting, compaction, surface finishing, polishing, spraying, maintenance, and maintenance work after pervious concrete pouring molding, which are important links in the pervious concrete construction process. As an inorganic cementing material is added into the pervious concrete, the early strength of the concrete is increased quickly, hydration heat can be generated by cement hardening, and sufficient water is needed for cooling, the foundation soil is tamped before the pervious concrete is laid, and then a layer of filtering geotechnical cloth is laid, so that the foundation soil is prevented from being submerged by rainwater to block pores of the pervious concrete, and the service life of the pervious concrete is prolonged. When a rainstorm season arrives and water on a base layer is too much and cannot permeate, a special permeable blind pipe drainage system is arranged, and a low-end drainage system is led to a road, so that excessive rainwater can be drained in time.
本发明公开了一种聚氨酯碎石透水路面施工方法，包括以下步骤：前期准备、制备碎石料和聚氨酯胶粘剂、制备混合料、铺料、切缝、压实、压实、收面、打磨、喷涂、养护，透水混凝土浇筑成型后的养护工作，是透水混凝土施工过程中的重要环节，由于透水混凝土内添加了无机胶结材料，混凝土的早期强度增长较快，水泥硬化会产生水化热，需要充足水分来降温，通过透水混凝土铺设前应先将基础土夯实，再铺设一层过滤土工布，有利于防止雨水对基础土的淹没堵塞透水混凝土孔隙，当暴雨季节到来时，当基层水过多无法渗透时，通过设置专用的透水盲管排水系统，将低端排水系统引至道路，有利于及时排除过量雨水。
