Method for removing existing open cut tunnel latticed column pile foundation in soft soil area operation state
The invention discloses a method for removing an existing open cut tunnel latticed column pile foundation in a soft soil area operation state. A transverse pipeline is arranged over the latticed column pile needing to be removed; an operation platform is arranged at the position, corresponding to the latticed column pile, of the transverse pipeline, and a framed bent structure is arranged on the operation platform; a pipe structure formed by a plurality of sleeves is arranged outside the latticed column pile in a cutting and tunneling mode through a drilling machine; then, the latticed column piles are hoisted out through a framed bent structure and transported out after being cut in a segmented mode; and finally, the sleeve is recycled section by section, C10 concrete is poured into a hole formed by removing the latticed column pile, and the bottom of the transverse pipeline is repaired. According to the method, the pile foundation can be removed according to needs on the premise that normal operation of the tunnel is not affected and large disturbance is not generated on the structure.
本发明公开了软土地区运营状态下既有明挖隧道格构柱桩基的清除方法；在需要清除的格构柱桩的正上方设置一横向管道；在横向管道对应格构柱桩的位置设置操作平台，并在操作平台设置排架结构；然后格构柱桩外通过钻机切削掘进设置一由多个套筒形成的管结构；然后通过排架结构吊出格构柱桩，并分段切割后运出；最后逐段回收套筒，并在清除格构柱桩所形成的孔洞内浇筑C10混凝土，并对横向管道的底部进行修补。本发明能够实现在不影响隧道正常运营且不对结构产生较大扰动的前提下，按需清除桩基。
