摘要
常规的土纠偏是掏在作业井、槽内实施的 ,这在地下水位较高的情况下会遇到较大的困难 .在一栋六层住宅楼的纠偏工程中 ,为了避开地下水的影响 ,开展了高压水射流掏土的工艺实验 .整个实验过程是借助旋喷注浆机具在地表完成的 .实验结果表明 ,采用高压水射流掏土不仅完全能够达到纠偏的设计要求 ,而且只要遵循少量、多次的掏土原则 ,施工时加强沉降观测 。
The common method of digging soil to rectify building's inclination was usually carried out in operating wells or slots, so it was not suitable for the case of high groundwater level. To avoid the influence of groundwater, a method digging soil by high-pressure water jet was designed and tested combined with the work rectifying a six-story building that built on soft soil. Using jet grouting machines and tools, the digging method was performed on ground and the experimental result showed that it was an effective and safe method.
