Exposed aggregate pervious concrete construction method for water environment treatment
The invention provides an exposed aggregate pervious concrete construction method for water environment treatment, which comprises the following steps: stirring on site to prepare concrete, ensuring the quality of the concrete, sequentially paving a sand gravel cushion layer, pervious concrete and exposed aggregate pervious concrete, uniformly paving manually, distributing materials by using a shovel in a reverse buckling manner, and ensuring the loose paving coefficient to be 1.1. Meanwhile, plastic cloth covering, strickling, vibrating, surface finishing and smoothing, cleaning agent spraying, exposed aggregate flushing, maintenance, pavement joint cutting and joint filling are prepared, polyurethane flexible glue is adopted for filling joints, the filled polyurethane flexible glue is not higher than the surface of aggregate pervious concrete, and smoothing and leveling treatment is conducted on a polyurethane flexible glue surface layer; protective treatment is conducted on the twosides of the aggregate pervious concrete joint through masking tapes; and 11) cleaning the surface of the aggregate pervious concrete by adopting a high-pressure cleaning machine, spraying a double-acrylic polyurethane sealant after the surface is dried for 24 hours, and arranging an enclosure around the ground which is just sprayed until the pavement is formed. The exposed aggregate pervious concrete construction method has advatanges.
本发明提供了一种用于水环境治理的露骨料透水混凝土施工方法，包括以下步骤：现场搅拌制备混凝土，保障混凝土质量，依次铺砂砾石垫层、透水混凝土和露骨料透水混凝土，采用人工均匀摊铺，用铁锹反扣式布料，松铺系数为1.1，同时准备覆盖塑料布，刮平，振捣，表面修整收光，喷涂清洗剂，露骨料冲洗，养护，路面切缝和填缝，采用聚氨酯软胶对缝进行填充，填充的聚氨酯软胶不高于骨料透水混凝土表面，对聚氨酯软胶面层进行收光找平处理；骨料透水混凝土缝两边用美纹纸做保护性处理；11）采用高压清洗机对骨料透水混凝土的表面进行清洗，表面干燥24小时后即可进行喷涂双丙聚氨酯密封剂，刚喷涂完的地面周围设置围护，直到路面成型。该具有的优点。
