Construction method of expansive soil stratum shield grinding pile
The invention discloses a construction method of an expansive soil stratum shield grinding pile. The construction method comprises the steps that a cutterhead structure is improved; anti-settling operation is performed on a pile body; pile body settlement monitoring points are arranged; a tunneling process is controlled before pile grinding; a pile grinding process is controlled; According to theconstruction method of expansive soil stratum shield grinding pile, the influence on the upper pile body during the shield pile grinding can be found and adjusted in time by monitoring the pile body,the tunneling speed of a shield tunneling machine and the rotating speed of the cutterhead are stabler by controlling the speed, harm caused by unbalanced soil pressure is reduced, the influence on the upper pile body in the pile grinding process is reduced through setting of related parameters in the tunneling process, therefore, the influence on a ground structure is reduced, and a tunnel and the upper pile body are protected after the shield tunneling machine penetrates through the pile body.
本发明公开一种膨胀土地层盾构磨桩的施工方法，包括步骤：刀盘结构改进设置；对桩体实施防沉降操作；布置桩体沉降监测点；磨桩前掘进过程控制；磨桩过程控制；本发明通过对桩体的监测能够发现盾构磨桩时对上部桩体的影响并及时调整，对速度的控制使得盾构机掘进速度与刀盘转速更加平稳，降低由于土压不平衡造成的危害，掘进过程中对相关参数的设置减小磨桩过程中对上部桩体的影响，从而降低对地面构筑物的影响，穿越桩体后，对隧道及对上部桩体的保护。
