高水头大流量管道型渗漏定量控制反向灌浆封堵新技术

摘要

Aiming at the pipeline leakage with high head and large flow ,the traditional treatment under the conditions of flowing water will cause some problems ,such as construct difficult ,poor effect ,long duration ,material seriously waste . In order to solve the economic and technological controllability problem ,a new technique of quantitative control of reverse grouting has been proposed and a patented device which can create static water environment for grouting has been devel-oped as well .%针对现有动水条件下处理高水头大流量管道型渗漏时，存在的处理难度大、效果差、工期长、材料浪费严重，技术经济的可控性差问题，研发了能构建静水环境的专利装置止水灌浆盒，提出了定量控制反向灌浆封堵新技术，并成功应用于工程实践。
