I-shaped stiffening core pulling-out method for stiffening core curtain pile and dado pile anchor combined support
The invention provides an I-shaped stiffening core pulling-out method for a stiffening core curtain pile and dado pile anchor combined support. I-shaped steel pulling-out equipment is adopted for pulling in the method, the pulling-out equipment comprises a base, a pile pulling hydraulic rod is fixed to the base, one end of a force transmission arm is in sliding connection with the pile pulling hydraulic rod, the other end of the force transmission arm is connected with symmetrically-distributed clamping devices through bolts, the clamping devices comprise clamp plates, grooves are formed in one ends of the clamp plates, vertical steel elastic pieces are symmetrically arranged inside each groove, spring base plates are arranged on the upper portions of the other ends of the clamp plates, the bolts penetrate through the clamp plates, the spring base plates and springs, the upper ends of the springs abut against nuts, the lower ends of the springs abut against the spring base plates, andthe clamp plates keep horizontal by adjusting the nuts. The equipment conforms to the structural stress characteristic, and is compact and simple in structure, small in size, simple in manufacturing process, easy to control, low in cost and good in mobility. After underground structure construction is finished, I-shaped steel is pulled out, the I-shaped steel is reused, so that social resources are saved, and space pollution caused by the fact that the I-shaped steel is left underground is avoided.
本发明提供一种劲芯帷幕桩与护壁桩锚联合支护的工字型劲芯拔出方法，采用工字钢拔出设备拔出，拔出设备包括底座，底座上固定有拔桩液压杆，传力臂一端与拔桩液压杆滑动连接，另一端与对称分布的夹持装置分别通过螺栓连接；夹持装置包括夹具板，夹具板一端设有凹槽，凹槽内部对称设有竖向钢弹片，夹具板另一端上部设有弹簧垫板，螺栓穿过夹具板、弹簧垫板和弹簧，弹簧上端顶住螺母，弹簧下端抵在弹簧垫板上，调整螺母，夹具板保持水平。本发明符合结构受力特点，结构紧凑简单、体积小、制造工艺简单、控制简单、成本低、可移动性好。在地下结构施工结束后将工字钢拔出，工字钢得到重复利用，节约社会资源，并避免工字钢留在地下造成空间污染。
