Synchronous deviation correction construction method for inserting and driving super-long large-diameter PHC inclined pile
The invention relates to a synchronous deviation rectifying construction method for inserting and driving an ultra-long large-diameter PHC inclined pile. The synchronous deviation rectifying construction method comprises the following steps that a deviation rectifying pile head is prefabricated, and a deviation rectifying control system is manufactured; a guide sleeve is installed on the ground; the deviation rectifying control system is temporarily fixed in the PHC pipe pile, and the prefabricated deviation rectifying pile head is installed at the lower end of the PHC pipe pile; the PHC pipe pile is hoisted and placed on a pile driver, and the axis of a pile body is aligned with the designed axis; the PHC pipe pile is hammered through a pile hammer, the axis of a pile body is monitored through a double-shaft dynamic tilt angle sensor, if the axis of the pile body deflects, a prefabricated deviation rectifying pile head is rotated to enable a deviation rectifying wing plate to be perpendicular to the plane where the designed axis and the axis of the pile body are located, and the deviation rectifying wing plate is ejected out of a strip-shaped wing plate hole; the PHC pipe pile is hammered, so that the pile body axis of the PHC pipe pile deviates towards the design axis; after the axis of the pile body coincides with the designed axis, the deviation rectifying wing plate retracts into the circular side plate; the PHC pipe pile continues to be hammered to the designed depth; and after the PHC pipe pile is implanted into the designed depth, the deviation correction control system is pulled out of the PHC pipe pile.
本发明涉及的超长大直径PHC斜桩插打同步纠偏施工方法，包括以下步骤：预制纠偏桩头及纠偏控制系统制作；在地面安装导向套筒；将纠偏控制系统临时固定在PHC管桩内，将预制纠偏桩头安装在PHC管桩下端；将PHC管桩吊起并放置在打桩机上，桩身轴线与设计轴线对齐；通过桩锤锤击PHC管桩，通过双轴动态倾角传感器监测桩身轴线，若桩身轴线发生偏转，转动预制纠偏桩头使纠偏翼板垂直于设计轴线和桩身轴线所在平面，将纠偏翼板从条形翼板孔顶出；锤击PHC管桩，使PHC管桩的桩身轴线向设计轴线偏移；待桩身轴线与设计轴线重合后，将纠偏翼板缩回圆形侧板内；继续锤击PHC管桩至设计深度；PHC管桩植入设计深度后，将纠偏控制系统从PHC管桩内拉出。
