Self-adaptive deformation flexible pile anchor for foundation pit supporting
The self-adaptive deformation flexible pile anchor comprises a top beam, a fender post, an anchor rod, an anchor head, a self-adaptive deformation control module and a connecting rod, the lower portion of the fender post is inserted into a foundation pit, the top beam is installed on the upper portion of the fender post, a reserved hole channel is formed in the upper portion of the anchor rod, and the connecting rod is inserted into the reserved hole channel; the connecting rod is connected with the anchor rod through the self-adaptive deformation control module, the anchor rod is inserted into a deep soil body, and the outer end of the connecting rod is connected with the anchor head. The self-adaptive deformation control module is combined to adapt to deformation of the fender post under the action of a vibration load, the fender post and a surrounding soil body are made to displace in the opposite direction of initial deformation through the elastic resistance of the high-strength spring and the anchoring force of the anchor rod, and the self-adaptive deformation flexible pile anchor structure is used for consuming energy of the vibration load; and the function of the anchor rod anchored in the deep soil body is fully played, so that the stability of the self-adaptive deformation flexible pile anchor structure of the foundation pit support is kept in the construction load and the vehicle vibration load.
本发明公开了一种用于基坑支护的自适应变形柔性桩锚，包括冠梁、围护桩、锚杆、锚头、自适应变形控制模块和连接杆，围护桩的下部插入基坑内，冠梁安装在围护桩的上部，锚杆的上部设置有预留孔道，连接杆插入预留孔道内，连接杆通过自适应变形控制模块连接锚杆，锚杆插入深层土体内，连接杆的外端连接锚头。本发明结合自适应变形控制模块来适应振动荷载作用下围护桩的变形，并且利用高强弹簧的弹性抗力、锚杆的锚固力使围护桩和周围土体向着初始变形的反方向位移，利用自适应变形柔性桩锚结构消耗振动荷载的能量，充分发挥锚固在深层土体中的锚杆的作用，使得基坑支护的自适应变形柔性桩锚结构在施工荷载和车辆振动荷载中保持其稳定性。
