摘要
某炼油厂减压塔座落在湿陷性地基上。经改建，荷载增大，地基需进行加固处理。通过比较，决定采用三重管喷射注浆法对湿陷性土地基进行加固。本文详细介绍了早强剂选用、施工工艺、施工进度控制、沉降观测等方面的技术问题。
A vacuum flasher of a certain Oil Refinery is located on collapsible soil Due to its rebuild- ing, the load is increased and the foundation soil needs to be improved. Through comparison,the triple -pipe chemical churning Process was adopted to strengthen the collapsible founda- non soil. The adoption of instant coagulant, construction process, progress control of cons -truction, observation of setllement and other technical problems are also introduced in detailin the paper.
