Underground water supply and drainage pipeline pressure-bearing leakage repairing method
The invention discloses a method for repairing pressure-bearing leakage of an underground water supply and drainage pipeline, which comprises the following steps of: distributing holes around a water burst area of the water supply and drainage pipeline, drilling from the ground according to hole distribution positions, and performing anti-seepage consolidation on a rock-soil body around the water burst area of the water supply and drainage pipeline through a grouting pipe to form a water stop structure wrapping the water supply and drainage pipeline. Therefore, the water burst area of the underground water supply and drainage pipeline can be quickly repaired. According to the scheme that the water supply and drainage pipeline leakage area is subjected to hole drilling, grouting and surrounding of the hole body for sealing and water stopping, the whole area is subjected to anti-seepage reinforcement, and the problems that excavation is needed and leakage points are difficult to position accurately in traditional pipeline external repairing treatment are solved.
本发明公开了一种地下供排水管道承压渗漏修补方法，在供排水管道涌水区域的周围布孔，根据布孔位，从地面开始钻孔，通过注浆管对供排水管道的涌水区域周边的岩土体进行防渗固结，形成一种包裹供排水管道的止水结构，以达到对地下供排水管道涌水区域的快速修补。本发明通过对供排水管道渗漏区域采用钻孔注浆环包洞身封闭止水的方案，对这一区域整体进行防渗加固，解决传统管道外修复处理，需要开挖且漏点难以精准定位的问题。
