Construction method and system for controlling disturbance of existing adjacent pipelines in foundation pit excavation
The invention discloses a construction method and system for controlling disturbance of an existing adjacent pipeline during excavation of a foundation pit, and the method comprises the steps: firstly, carrying out the statistics of the shape of a boundary line, close to the pipeline, of a unit boundary of the foundation pit before construction; supporting rods with different distribution densities are arranged in the area from the bottom of the pipeline to the foundation pit unit boundary line so as to achieve important protection of part of the area, and then a mechanical protection plate is laid on the basis of the supporting rods; the shape of a boundary line, close to one side of the foundation pit, of the mechanical protection plate is consistent with that of a boundary line of a foundation pit unit boundary, a plurality of U-shaped hooks are inserted in the pipeline at uneven intervals, and the U-shaped hooks are used for fixing the pipeline to a wall on one side.
本发明公开了基坑开挖控制已有临近管线扰动的施工方法及系统，包括步骤有：首先在施工之前统计基坑单元界靠近管线的边界线的形状，然后，在管线的底部到基坑单元界边界线的区域设置不同分布密度的支撑杆以做到部分区域重点的防护，然后在支撑杆的基础上铺设机械防护板；所述的机械防护板靠近基坑一侧的边界线形状与基坑单元界的边界线的形状一致，在所述的管线上，按照不均匀的间隔插设若干个U型钩，所述的U型钩用于将管线固定在一侧墙体上。
