Municipal rainwater and sewage pipeline inner wall grouting repairing method
The invention relates to the technical field of municipal engineering, in particular to a municipal rainwater and sewage pipeline inner wall grouting repair method. The method comprises the following steps of S1, dredging and desilting, specifically, dredging sludge or disintegrating slag on the inner wall of a municipal rainwater and sewage pipeline by using cleaning equipment, and discharging sludge in the rainwater and sewage pipeline to thoroughly clean the inner wall of the rainwater and sewage pipeline; S2, detecting the leakage position of the pipeline, specifically, detecting the leakage position of the rain and sewage pipeline by using infrared imaging detection equipment; and S3, cleaning the leakage base surface, specifically, finding out the leakage position of the rain and sewage pipeline, mounting a steel wire brush on the steel rod, extending the steel rod into the rain and sewage pipeline, cleaning the leakage base surface of the pipeline by using the steel wire brush, and cleaning and removing mortar bulges and sand slag. According to the method, the polyurethane grouting liquid can fill cracks after expansion, the silicon dioxide, the cement and the expanding agent are subjected to secondary grouting, the surface adsorption capacity of the silicon dioxide is high, the silicon dioxide can be mixed with the cement and the expanding agent to repair a pipeline, and the oxidation resistance and the strength of the pipeline are improved.
本发明涉及市政工程技术领域，具体是一种市政雨污管道内壁注浆修复方法，包括以下步骤：S1.疏通清淤：将市政雨污管道内壁的淤泥或碎渣使用清洗设备进行疏通，并将雨污管道中的污泥排出，雨污管道内壁清理彻底；S2.探测管道渗漏处：使用红外成像检测设备检测雨污管道的渗漏处；S3.渗漏基面清洁：寻出雨污管道的渗漏处，钢杆上安装钢丝刷并伸入到雨污管道的内部，对管道的渗漏基面使用钢丝刷清理，砂浆凸起和砂渣清理去除。本发明中的聚氨酯注浆液能够在膨胀后使裂缝填充，二氧化硅、水泥和膨胀剂进行二次注浆，二氧化硅的表面吸附力较强，可与水泥和膨胀剂混合后对管道修复，提高了管道的抗氧化和强度。
