Rapid construction method for road surface municipal well curb
The invention relates to the technical field of municipal engineering, and discloses a rapid construction method of a road surface municipal well curb, which specifically comprises the following steps: S1, setting a construction range near a municipal well, dismantling the municipal well curb, removing a cast iron well lid by using an excavator in cooperation with manual work, cleaning impurities such as well curb concrete fragments, laitance and stone chips, and cleaning the bottom of the well curb; S2, preparing materials, mounting a forced stirrer, starting the forced stirrer, putting the coarse aggregate into the stirrer, then sequentially adding the cement, the fine aggregate, the silicon powder, the steel slag and the steel fiber while stirring, and continuously performing stirring for 1-2 minutes; and S3, adding a high-efficiency water reducing agent and a retarder into water according to the proportion, and draining the water mixed with the admixture into a stirrer for stirring for 2-4 minutes. The high-strength concrete disclosed by the invention is quick-hardening concrete which is mixed on site in situ, so that the design strength required by road surface driving can be achieved within 1 hour, and the economic and social benefits of municipal administration and traffic are effectively reduced.
本发明涉及市政工程的技术领域，公开了路面市政井圈的快速施工方法，具体包括如下步骤：S1：在市政井的附近设置好施工范围，拆除市政井的井圈，用挖掘机配合人工移除铸铁井盖，清理井圈混凝土碎块、浮浆、石屑的杂物，将井圈底部清理干净；S2：准备好材料，安装好强制式搅拌机，并启动强制式搅拌机，在搅拌机内放入粗骨料，然后边搅拌边依次加入水泥，细骨料，硅粉、钢渣、钢纤维，持续搅拌1‑2min；S3：将高效减水剂、缓凝剂按照比例加入水中，将混合外加剂后的水引流至搅拌机内搅拌2‑4min。本发明的高强混凝土是在现场原位拌制的快硬混凝土，确保了在1h内即可达到路面行车所需要的设计强度，有效地降低了市政和交通的经济和社会效益。
