压密注浆技术在住宅楼地基加固中的应用

Application of the Densified Mortar-Injection Technology in the Consolidation of Foundation of Residential Buildings

徐州市某住宅楼在主体施工期间发生不均匀沉降。对此，根据工程地质和现场施工条件，采用压密注浆并辅以高压旋喷桩方法对地基持力层进行加固，消除地基隐患，提高地基土承载力。加固达到了预期目的。

The technology of densified mortar-injection can consolidate the foundation of residential buildings so that its hidden perils are removed, its bearing capacity is enhanced and its consolidation meets the desired result.
