上海地铁１号线南苏州河路旁通道及中间水泵站，要求采用方形立井地面开挖，开挖后再用盾构式掘进机掘进。开挖深度２４ｍ，在淤泥质软土地层中，又紧挨苏州河，建设的难度极大。施工中首次采用三重管高压旋喷注浆与灌注桩复合加固技术加固软土，帷幕封水，攻破地铁建设中又一个难题。本文着重介绍该法的施工技术与施工工艺，供设计、施工人员参考 Shanghai Subway Line 1 South Suzhou Creek roadside access and intermediate pumping station, requires the use of square shaft ground excavation, excavation and then shield TBM. Excavation depth of 24m, in the silt soft soil formation, and close to the Suzhou River, the construction of great difficulty. Construction for the first time using triple-tube high pressure jet grouting and bored pile composite reinforcement technology to strengthen soft soil, curtain closure, break the subway construction is another problem. This article focuses on the law of construction technology and construction technology for design, construction personnel reference
