End reinforcement configuration system and method for pipe jacking receiving well close to existing subway tunnel
The invention discloses a reinforcing configuration system and method for the end of a pipe jacking receiving well close to an existing subway tunnel. A model comprises a pipe jacking pipeline; the MJS construction method pile is used for reinforcing a pipe jacking starting well and a pipe jacking receiving well and is arranged on one section of the pipe jacking pipeline; the receiving well is formed in one side of the MJS construction method pile; the cast-in-situ bored pile is arranged on the surface of the receiving well; the jet grouting pile is arranged on the surface of the cast-in-situ bored pile; the method comprises the steps that a site is arranged, road surface obstacles are cleared away, a slurry discharging groove is excavated, equipment is installed, a pile machine is in place, measurement and paying-off are conducted, centering construction is conducted through an MJS pile machine, a drill rod is lowered into a guide hole to the designed depth, and a drill bit reaches the preset depth. When the drill bit reaches the preset construction depth, construction is started, the drill rod is detached, and then the drill rod is washed and maintained, the system and method can well control underground pressure, the diffusion range of cement paste in the stratum can be effectively controlled, and underground water is prevented from being polluted.
本发明公开一种临近既有地铁隧道顶管接收井端头加固配置系统及方法，所述模型包括：顶管管线；MJS工法桩，用于对顶管始发井和接收井进行加固，设置在所述顶管管线的一段上；接收井，开设在所述MJS工法桩的一侧；钻孔灌注桩，开设在所述接收井的表面上；旋喷桩，设置在所述钻孔灌注桩的表面上；所述方法包括：布置场地，清理路面障碍物，开挖排浆沟槽，设备安装，桩机就位，测量和放线，MJS桩机对中施工，在引孔内下放钻杆至设计深度，钻头到达预定深度；当钻头到达预定施工的深度后，开始施工，拆卸钻杆后，对钻杆进行冲洗保养，所述系统及方法能很好的控制地内压力，并能够有效控制水泥浆在地层中的扩散范围，避免污染地下水。
