Anchor rod pile reinforcement cage and construction method of anchor rod pile
The invention discloses an anchor rod pile reinforcement cage. The anchor rod pile reinforcement cage comprises a cylindrical reinforcement cage body and anchor rods. A plurality of radiation ribs are arranged around the cylindrical reinforcement cage, the radiation ribs are hinged to the cylindrical reinforcement cage, each radiation rib comprises an expansion rib and a driving rod, the driving rods extend into the cylindrical reinforcement cage, and the expansion ribs are located outside the cylindrical reinforcement cage; the upper end plate is fixedly installed on the anchor rod, the plug pin is movably inserted in the upper end plate, the driving plate is located in the cylindrical reinforcement cage and movably arranged on the anchor rod in a sleeving mode, the elastic piece is arranged between the upper end plate and the driving plate, and the driving plate is hung on the upper end plate through the limiting rope. The driving plate can drive the radiation ribs to rotate outwards through the elastic pieces. The invention further discloses a construction method of the anchor rod pile. The radiation ribs are of a fixed structure, the diameter of the expanded-head reinforcement cage is changed in a rotating mode, the mode that the diameter is changed through elastic deformation in an existing structure is changed, and the problem caused by plastic deformation of an existing elastic rib is avoided.
本申请公开了一种锚杆桩钢筋笼，其包括筒状钢筋笼和锚杆；环绕筒状钢筋笼布置有若干辐射筋，辐射筋铰接在筒状钢筋笼上，辐射筋包括扩展筋和驱动杆，其中驱动杆伸入到筒状钢筋笼内，扩展筋位于筒状钢筋笼外；上端板固定安装在锚杆上，插销活动地插设在上端板上，驱动板位于筒状钢筋笼内并活动地套设在锚杆上，弹性件设置上端板与驱动板之间，驱动板经限位绳吊挂在上端板上，将插销从上端板上拉脱后，利用弹性件能够驱动板带动辐射筋向外转动。本申请还公开了一种锚杆桩的施工方法。本申请中辐射筋为固定结构，利用转动方式使扩大头钢筋笼进行变径，改变了现有结构中采用弹性形变来进行变径的方式，避免了现有弹性筋由于塑性变形而产生的问题。
