骑跨污水管的地下连续墙施工方法探讨

Discussion on Construction Method of Diaphragm Wall Crossing Sewage Pipe

在地下连续墙施工过程中遇到现有地下管线时,通常会采用切改地下管线的措施,或将地下管线临时移位到扩大的路面,但有时也存在无法迁移管线的情况。提出了一种骑跨污水管的部分逆作法地下连续墙,包括污水管影响范围之外的左幅现浇地下连续墙、右幅现浇地下连续墙、上部现浇地下连续墙及污水管周边的逆作法施工地下连续墙,污水管被包裹在逆作法施工地下连续墙中,确保地下连续墙对污水管的影响最低到最小。

The existing underground pipelines are encountered during the construction of underground diaphragm wall.Measures of cutting and changing the underground pipelines are usually adopted,or the underground pipelines are temporarily moved to the expanded pavement, but sometimes the pipelines cannot be moved. A partial reverse construction diaphragm wall crossing the sewage pipe is proposed, including the left cast-in-situ diaphragm wall, the right cast-in-situ diaphragm wall, the upper cast-in-situ diaphragm wall and the reverse construction diaphragm wall around the sewage pipe. The sewage pipe is wrapped in the reverse construction diaphragm wall to ensure that the impact of diaphragm wall on sewage pipe is minimized.
