Deviation correction method for staged drilling pressure relief and backward extrusion of inclined foundation pile
The invention relates to a deviation correction method for staged drilling pressure relief and backward extrusion of an inclined foundation pile. The deviation correction method comprises the following steps that the deviation condition of the foundation pile is determined; a first pressure relief hole is constructed in the front side of the deviation rectifying and returning direction of the foundation pile, and the size is smaller than the deviation size of the foundation pile; an extrusion pile is driven into the rear side of the deviation rectifying and returning direction of the foundation pile, so that the foundation pile moves towards a preset position; determining the residual deviation correction condition of the foundation pile; according to the residual deviation rectifying condition, a second pressure relief hole is constructed in the front side of the deviation rectifying and returning direction of the foundation pile, and the size is larger than the residual deviation rectifying size of the foundation pile; and the other row of new extrusion piles are driven into the rear side of the deviation rectifying and returning direction of the foundation pile, so that the foundation pile moves towards the preset position, and deviation rectifying of the foundation pile is completed. According to the method, the pressure relief hole is drilled in one side of the foundation pile, the extrusion pile is sunk into the other side of the foundation pile, the deviated foundation pile is made to return to one side of the pressure relief hole, deviation correction is conducted twice, extrusion force borne by the foundation pile is reduced, the probability that a pile body is damaged is reduced, and the quality of the pile body is improved.
本发明涉及一种倾斜基桩分阶段钻孔泄压及反向挤压的纠偏方法，包括如下步骤：确定基桩的偏移情况；向基桩纠偏回正方向的前侧施工第一泄压孔，体积小于基桩的偏移体积；向基桩纠偏回正方向的后侧打入挤压桩，以使得基桩向预设位置进行移动；确定基桩的剩余纠偏情况；根据剩余纠偏情况，向基桩纠偏回正方向的前侧施工第二泄压孔，体积大于基桩的剩余纠偏体积；向基桩纠偏回正方向的后侧打入另一排新的挤压桩，以使得基桩向预设位置进行移动，以完成基桩的纠偏。本发明在基桩的一侧钻泄压孔，另一侧沉入挤压桩，让偏位的基桩向泄压孔的一侧回正，且纠偏分两次进行，降低了基桩收到的挤压力，减少了桩身受损的概率，提高了桩身质量。
