Bottom expanding device and construction method of punching bottom expanding cast-in-place pile
The invention relates to a bottom expanding device of a punching bottom expanding cast-in-place pile and a construction method, and belongs to the field of punching bottom expanding cast-in-place pile construction technologies. The pile expanding device comprises a pile expanding head connected to the tail end of a drill rod, the pile expanding head comprises a fixing shaft and a sleeve arranged on the fixing shaft in a sleeving mode, the fixing shaft is connected with the drill rod, the two sides of the fixing shaft and the two sides of the sleeve are jointly connected with two bottom expanding wings, and the bottom expanding wings are folded towards the fixing shaft and unfolded away from the fixing shaft. A fixed shaft is arranged at the bottom of the bottom-expanded wing, a drill bit is arranged on the side, away from the fixed shaft, of the bottom-expanded wing, a supporting assembly is arranged between the bottom-expanded wing and the fixed shaft and used for supporting the bottom-expanded wing when the bottom-expanded wing is unfolded, and a slag collecting assembly is further arranged at the bottom of the fixed shaft and used for collecting and storing large-size sediment. The device has the effect of solving the problem that sediment with large size is inconvenient to clean.
本申请涉及一种冲孔扩底灌注桩的扩底装置及施工方法，属于冲孔扩底灌注桩施工技术的领域。其包括连接在钻杆末端的扩桩头，所述扩桩头包括固定轴、套设在固定轴上的套管，所述固定轴与钻杆连接，所述固定轴与套管的两侧共同连接有两个扩底翼，所述扩底翼朝向固定轴折叠、远离固定轴展开，所述扩底翼背离固定轴的一侧设置有钻头，所述扩底翼与固定轴之间设置有支撑组件，所述支撑组件用于在扩底翼展开时对扩底翼进行支撑，所述固定轴的底部还设置有集渣组件，所述集渣组件用于对大体积沉渣进行收集储存。本申请具有改善体积较大沉渣不便于清理的问题的效果。
