Expansion type pile foundation pouring process
The invention discloses an expansion type pile foundation pouring process, and belongs to the field of pile foundation pouring, the expansion type pile foundation pouring process comprises the following steps: S1, drilling equipment is mounted at the output end of a drilling machine; s2, drilling operation is carried out; s3, when drilling is carried out to the bottom of the pile foundation hole, a driving shaft is pulled back to enable drilling equipment to move upwards by a certain distance, a double-end hydraulic supporting rod is used for synchronously driving two vortex line type buckets to be away from each other, hole expanding operation is carried out, and the bottom of the pile foundation hole is excavated into a conical structure in an expanding mode; s4, after impact reaming operation is completed, the vortex-type bucket is recycled, slurry is poured into the pile foundation hole, and the driving shaft is slowly rotated; and S5, after hole cleaning is completed, the pile foundation concrete pouring procedure can be completed through the prefabricated reinforcement cage and pouring cement. According to the technology, pile foundation holes are formed at a time, the drilling slag amount is small, the construction efficiency is high, and the technology has market prospects and is suitable for popularization.
本发明公开了一种膨胀式桩基浇筑工艺,属于桩基浇筑领域,一种膨胀式桩基浇筑工艺,包括以下步骤:S1、在钻孔机的输出端安装钻孔设备;S2、进行钻孔作业;S3、钻孔进行至桩基孔底部时,回拉驱动轴使钻孔设备上移一定距离,利用双头液压支撑杆同步驱动两个涡线型挖斗相远离,进行扩孔操作,将桩基孔底部扩挖成锥形结构;S4、完成冲击扩孔操作后,回收涡线型挖斗,泥浆灌入桩基孔,缓慢转动驱动轴;S5、完成清孔后即可将预制好的钢筋笼,浇筑水泥完成桩基混凝土浇筑工序,本工艺桩基孔一次成型,钻渣量少,施工效率高,具市场前景,适合推广。
