市政工程顶管施工发生管道抱死现象的解决办法

Solution to the Phenomenon of Pipe Lock in the Construction of Municipal Engineering Pipe Jacking

在市政工程污水管道顶管施工过程中,遇到流沙层,并由于设备损坏维修后,发生抱管现象,致使顶管施工在中途无法继续顶进。经综合对比分析,采用"反顶+钢套管"的方法取出机头的同时并完成剩余管道的顶进工作。

In municipal engineering sewage pipe jacking construction process, encountered quicksand layer, and because of equipment damage maintenance, the occurrence of pipe holding phenomenon, resulting in the construction of pipe jacking in the middle can not continue to jacking. After comprehensive comparison and analysis, the method of "reverse jacking+steel casing" is adopted to take out the machine head and complete the jacking of the remaining pipelines.
