高压喷射注浆技术在基坑管涌处理中的运用

高压喷射注浆法是在注浆法的基础上，应用高压喷射技术而发展起来的一项新的地基加固方法。本文针对武汉市泰合广场基坑在开挖过程中形成管涌或流上而致使附近建筑物遭受严重破坏的问题，采用高压喷射注浆法施工工艺方法，杜绝了基坑壁管涌或流立现象，使基坑开挖和基础施工得以安全进行。

Application on Grouting Technology by High Pressure Spraying in Treatment Mud Surge of Pipes in Foundation Pit

The grouting method by high pressure spraying is a new ground foundation consolidationmethod, which is developed by high pressure spraying technology on the basis of the groutingmethod. This paper uses the construction process of grouting method by high pressure spraying tothe problern that the near buildings are seriously destroyed due to the mud surge or running earthof the pipes during the foundation pits excavation in Taihe Square, Wuhan City so as to stop themud surge or running earth of pipe wall in the foundation pits and to safely carry out the excava-tion of the foundation pits and the foundation construction.
