泥水平衡油气顶管带压开舱技术研究

Research on the Technology Slurry Balance Pipe Jacking with Pressurized Tank Opening

摘要: 在顶管法管道施工中遇到地下障碍物、刀具磨损更换等被迫停机时，需要进行开舱处理。依托富春江顶管工程实例，针对带压开舱前的掌子面止水、带压开舱等关键问题进行研究，制定了有效的解决措施，对今后的顶管带压开舱技术具有重要的借鉴意义。

Abstract: In the construction of pipes with jacking method, when it had to be shutdown in meeting under-ground obstacle and tool wearing and replacement, it was necessary to open the tank and handle it. In Fuchunjiang Pipe Jacking Engineering, in view of the key problems palm surface water stop and pressurized tank opening before the pressurized tank opening, effective measures are taken for solving the problems, it provides reference for future pressurized tank opening technology.
