城市排水管道的修复是城市市政工程工作中最基本的工作内容,在我国城市现代化建设的发展进程中,经常会对一些城区的地下排水管道进行维修与改造,尤其是在老城区,排水管道的修理与维护更是较为频繁。但由于城市建筑或排水管道所处位置不易动土开挖,这就要求市政工程施工人员在不开挖土层的基础上进行管道修复。因此,排水管道非开挖修复技术就显得非常重要。本文通过分析目前我国城市排水管道修复的施工现状,探讨了非开挖修复技术的主要施工方法,并指出非开挖修复技术在未来的排水管道施工中具有广阔的发展前景。 Urban drainage pipe repair is the most basic work in the municipal engineering work. In the process of urban modernization in our country, the maintenance and renovation of the underground drainage pipe in some urban areas are often carried out, especially in the old urban areas, drainage pipelines Repair and maintenance is more frequent. However, due to the location of urban buildings or drainage pipe is not easy to dig soil, which requires municipal construction workers in the excavation of soil based on pipeline repair. Therefore, the drainage trench trenchless repair technology is very important. In this paper, the current construction of urban drainage pipe repair in our country is analyzed. The main construction methods of non-excavation repair technology are discussed. It is pointed out that non-excavation repair technology has broad prospects for future drainage pipe construction.
