Construction method for adjacent deep foundation pits close to tramcar
The invention discloses a construction method for adjacent deep foundation pits close to a tramcar. The construction method comprises the steps that firstly, the two deep foundation pits are excavated in a staggered mode; and then the two excavated deep foundation pits are subjected to foundation pit enclosure, and the stability of the foundation pits and the safety of operation in the foundation pits are ensured. The two deep foundation pits are excavated in the staggered mode, compared with a synchronous excavation mode in the prior art, the situation that settlement of the tramcar is affected by large-area soil body unloading caused by long-strip-shaped foundation pit excavation is avoided, and the situation that the tramcar stops running or the running stability of the tramcar is affected due to rail settlement of the tramcar is avoided; and meanwhile, compared with a mode that the two deep foundation pits are excavated independently in the prior art, the construction period is shortened, the cost is reduced, and the control pressure is relieved.
本发明公开了一种临近有轨电车的相邻深基坑的施工方法,首先对两个深基坑错层开挖,然后对开挖完成的两个深基坑进行基坑围护,保证基坑的稳定性和基坑内作业的安全性。两个深基坑错层开挖,相对于现有技术中同步开挖的方式,避免开挖形成长条形基坑造成的大面积土体卸荷对有轨电车的沉降造成影响,避免了有轨电车的轨道沉降而导致的有轨电车停运或者对有轨电车运行平稳性的影响,同时相对于现有技术中两个深基坑独立开挖的方式,缩短了施工周期,降低了成本造价控制压力。
