Pile pulling construction method in underground passage
The invention discloses a construction method for pulling a pile in an underground passage. The construction method comprises the following specific steps of determining the position of an old pile, constructing an anchor pull rod, performing high-pressure cutting mud groove construction, putting pile pulling equipment in place, pulling the pile section by section and breaking the pile section by section. According to the method, the difficulty of adopting large mechanical equipment in the pile pulling construction with small channel clearance is overcome; normal passage of the underground passage is ensured, and traffic interruption is not needed; it is guaranteed that the underground passage is free of excessive deformation, monitoring data are stable, and construction safety is greatly guaranteed.
本发明公开了地下通道内拔桩施工方法，具体步骤如下：确定旧桩桩位，施工锚拉杆，高压切割泥槽施工，拔桩设备就位，分节拔桩，分节破除。本发明在通道净空小的拔桩施工中克服采用大型机械设备的难点；且保证地下通道的正常通行，不用中断交通；保证地下通道无过大变形，监测数据稳定，施工安全有极大地保障。
