Threaded soil sampling cast-in-situ bored pile wall protecting method
The invention discloses a threaded soil sampling cast-in-situ bored pile wall protecting method, and belongs to the technical field of building construction. Threaded drilling equipment is assembled, a drilling machine is assembled to conduct drilling according to a preset position, soil is automatically discharged due to the spiral action, and after drilling is conducted to the designed depth, a feeding hopper is arranged on the top to convey materials; the drilling machine is rotated in the reverse direction, meanwhile, the spiral blade applies vibration, the concrete is kept compact in the descending process, after the concrete is conveyed to the bottom of the hole, the spiral blade is lifted while rotating is started till the equipment is lifted out, a cylindrical protection wall is formed in the foundation, after the concrete protection wall reaches, a soil body in the middle of the protection wall is excavated, and a reinforcement cage is placed to form a pile. According to the method, the spiral drilling machine is large in torque and low in energy consumption, conveyed materials are not prone to being blocked, a material conveying opening is not blocked, and the method is wall-protecting, wide in application occasion and not limited to a single construction site. Through the retaining wall, the hole wall can be effectively prevented from collapsing, meanwhile, the construction cost is reduced, and the construction progress is accelerated.
本发明公开了一种螺纹取土钻孔灌注桩护壁方法，属于建筑施工技术领域，通过对螺纹钻孔设备组装，组装成钻机按照好预定位置进行钻孔，由于螺旋作用土自动排出，钻孔至设计深度后，通过顶部设置进料斗输料，反方向旋转钻机同时螺旋叶片施加振动，使混凝土在下降的过程中保持密实，待混凝土输送至孔底部，开始边旋转边上提螺旋片，直至提出设备后，在地基中形成圆筒形护壁，待混凝土护壁达到后开挖护壁中间的土体，放置钢筋笼成桩。此种方法采用螺旋钻机不仅钻机扭距大、能耗低，输送物料不易堵塞，输料口不堵塞，而且此种方法护壁，应用场合广泛，不局限单一的施工场地。通过此种护壁能有效的防止孔壁坍塌，同时降低了施工成本，加快施工进度。
