Pile foundation drilling construction method capable of preventing hole collapse
The invention relates to the field of building construction, in particular to a hole collapse prevention pile foundation drilling construction method which comprises the following steps that after drilling is completed, an auxiliary device is placed in a hole, the auxiliary device comprises a rotating shaft, an inner cylinder and an outer cylinder, and the outer cylinder comprises a plurality of arc-shaped plates distributed around the circumference of the inner cylinder; a plurality of rod holes are formed in the side wall of the inner cylinder, sliding rods are fixedly arranged on the inner wall of the arc-shaped plate and penetrate through the rod holes, and a tension spring is arranged between the inner cylinder and the arc-shaped plate; a cam block is fixedly arranged on the rotating shaft; then a clamping and fixing device is fixedly placed on the ground; then backfilling concrete; after initial setting of the concrete, a rotary drilling machine is used for driving a rotating shaft to rotate, and meanwhile, a clamping and fixing device is used for intermittently clamping and fixing the inner cylinder; the auxiliary device is then taken out of the hole, and then the hole is re-drilled. By means of the scheme, the problem that in the prior art, excessive concrete is wasted in the process of re-drilling after the holes are backfilled with concrete is solved.
本发明涉及建筑施工领域，具体涉及一种防塌孔的桩基钻孔施工方法，包括以下步骤：钻孔完毕后，在孔中放置辅助装置，辅助装置包括转轴、内筒和外筒，外筒包括围绕内筒圆周分布的多个弧形板；内筒侧壁设有多个杆孔，弧形板的内壁上固定设有滑动杆，滑动杆穿过杆孔，内筒和弧形板之间设有拉簧；转轴上固定设有凸轮块；然后在地面上固定放置夹持固定装置；然后回填混凝土；然后孔内壁压实操作：待混凝土初凝后，使用旋挖机带动转轴转动，同时使用夹持固定装置对内筒进行间歇性夹持固定；然后将辅助装置从孔中取出，然后在孔中重新钻孔。通过本方案，解决了现有技术中向孔中回填混凝土后重新钻孔过程中造成的过多混凝土浪费的问题。
