Hard rock stratum square pile hole forming pouring construction method
The invention discloses a hard rock stratum square pile hole forming pouring construction method. The hard rock stratum square pile hole forming pouring construction method comprises the steps that arotary drilling rig is adopted for drilling a round hole in a square pile position; non-mechanical cutting type cutting equipment is used for cutting a square pile free area along a square pile position line to form blocky stone; an excavator is used for excavating a whole block of the blocky stone in a square pile hole to form a pit; and a crane is used for sinking a reinforcement cage in a formed hole. Firstly, the rotary drilling rig is used for excavating the round pile hole in the range of the square pile to form free face to release stress, then non-mechanical cutting equipment is used for performing linear cutting in the free area of the square pile hole, the cutting machine can cut in the oblique line direction, the situation that only a traditional linear cutting mode can be adopted is broken through, the total cutting stroke is reduced, a plurality of gravels large in size are formed, the improvement of the working efficiency of the excavator for whole-block pit discharging is facilitated, the noise is low in the cutting process, the situation that a cutting tool is crushed by hard stones is avoided, and the construction quality is high.
本发明公开了一种硬岩层方形桩孔成型灌注施工方法，包括在方形桩位处采用旋挖钻机进行钻圆孔，利用非机械切割式的切割设备沿着方形桩位线对方形桩临空区域进行切割形成块状石料，利用挖土机对方形桩孔内部的块状石料整块挖掘出坑，使用吊车在成孔内沉设钢筋笼等步骤，先利用旋挖钻机在方形桩范围内开挖圆形桩孔，形成临空面释放应力，再利用非机械式切割设备沿方形桩孔临空区域进行直线方向切割，还能进行斜线方向切割，突破了只能采用传统直线切割方式，减少了切割总行程，形成体积较大的多块碎石，有利于促进挖土机进行整块出坑的工作效率，切割过程噪音小，不会存在切割刀具被硬石块撞碎的情况，施工质量高。
