Pipeline cleaning and grouting construction method
The invention discloses a pipeline cleaning and grouting construction method. Firstly, a grouting operation pit is excavated and supported, then a combined pipe cleaner is used for cleaning a pipe for 1-3 times, chemical cleaning is carried out for 1-3 times, water cleaning is carried out for 1-3 times, and finally pipeline grouting is carried out. A grouting pump and high-pressure connection are used for grouting, the grouting mileage is long, the grouting density is high, the grouting mileage is about 7 kilometers, and the grouting density is further increased by using a water pushing ball process; the proportion of the grouting material is matched with the grouting pressure, and the initial grouting time is matched with the solidification time of the grouting material, so that the grouting material can flow in the pipeline, and the effect of timely solidification can be achieved.
本发明公开了一种管道清洗注浆施工方法。首先进行注浆作业坑开挖、支护，然后采用组合式清管器物理清管1‑3次，化学清洗1‑3次，水清洗1‑3次，最后进行管道注浆。本发明使用注浆泵并使用高压连接，进行注浆，注浆里程长，注浆密度高，注浆里程约为7公里，使用水推球工艺，进一步增加注浆密度；注浆材料的配比，与注浆压力相互配合，始注浆时间与注浆材料的凝固时间相互吻合，既能使注浆材料在管道内流动，有能达到及时凝固的效果。
