顶杆式阀注水泥浆液在钻探施工中的应用

摘要

Shengdajinpan earth subsidence monitoring group is located in the core area of Lujiazui CBD.Due to the limitations of the construction site,Shanghai Geology Survey Institute uses one well for several points,which is one of the technology demands of this project.In order to ensure the quality,our company uses pushing-rod valve grouting to solve the problems of consolidation.%盛大金磐地面沉降监测标组位于陆家嘴CBD核心区,由于施工场地的局限性,上海市地质调查院采用一井多用办法,鉴别孔兼做基岩标和第V承压含水层水文监测孔,标底与新鲜基岩80箛固结,是该工程技术要求之一,为了保证施工质量,我公司采用顶杆式阀注水泥浆液,解决标杆与基岩固结难题。
