Double-steel-casing rotary excavating hole-forming cast-in-place pile
The invention discloses a double-steel-casing rotary digging hole-forming cast-in-place pile which comprises an outer casing, a pile driver used for vertically inserting the outer casing into a riverbed is arranged on one side of the outer casing, the pile driver comprises a clamping device, the clamping device comprises an arc-shaped clamping rod and a mounting plate, the arc-shaped clamping rod is arranged on the mounting plate in a swinging mode, and the arc-shaped clamping rod is arranged on the mounting plate in a swinging mode. Elastic mechanisms are arranged on the inner sides of the arc-shaped clamping rods and comprise rolling wheels rotationally arranged on the connecting shafts, thrust springs are fixedly connected to the two ends of the connecting shafts, and the ends, away from the connecting shafts, of the thrust springs are fixedly connected to the side walls of the inner sides of the arc-shaped clamping rods; at least two sets of elastic mechanisms are located on the side faces of the inner sides of the arc-shaped clamping rods, the two sets of arc-shaped clamping rods are symmetrically located on the mounting plate, and a driving mechanism used for enabling the two arc-shaped clamping rods to be close to or away from each other is arranged on the mounting plate. The device has the effects that the positioning precision of the outer pile casing is improved, and meanwhile, the resistance of inserting the outer pile casing into the ground is reduced.
本发明公开了一种双钢护筒旋挖成孔灌注桩，包括外护筒，外护筒的一侧设置有用于将外护筒竖直插入河床的打桩机，打桩机包括夹持装置，夹持装置包括弧形夹持杆，夹持装置还包括的安装板，弧形夹持杆摆动设置于安装板上，弧形夹持杆的内侧设置有弹力机构，弹力机构包括转动设置于连接轴上的滚轮，连接轴的两端均固定连接有推力弹簧，推力弹簧远离连接轴的一端固定连接于弧形夹持杆的内侧侧壁上，弹力机构位于弧形夹持杆内侧侧面上至少设置有两组，弧形夹持杆位于安装板上对称设置有两组，安装板上设置有用于使两个弧形夹持杆相互靠近或远离的驱动机构。本申请具有提高外护筒的定位精度，同时降低外护筒插入地下的阻力的效果。
