Construction method and system for rotary digging hole-forming cast-in-place pile
The invention belongs to the technical field of cast-in-place pile hole forming, and particularly relates to a rotary excavating hole forming cast-in-place pile construction method and system. The method comprises the following steps that geological survey information of a site to be constructed is obtained, and a plurality of gravel layer steel protection cylinder pieces and a plurality of silt layer steel protection cylinder pieces are assembled into a gravel layer steel protection cylinder and a silt layer steel protection cylinder respectively; the diameter of the gravel layer steel casing is larger than that of the sludge layer steel casing; the gravel layer is rotationally excavated to obtain a first pile hole, a rolling supporting piece is inserted into the guide groove, the sludge layer is rotationally excavated to obtain a second pile hole, and the lower portion of the second pile hole continues to be rotationally excavated to obtain a third pile hole; the first pile hole, the second pile hole and the third pile hole jointly form a cast-in-place pile hole; after a reinforcement cage is placed in the cast-in-place pile hole, concrete is poured into the cast-in-place pile, the gravel layer steel casing is pulled out firstly, and then the sludge layer steel casing is pulled out; when the gravel bed steel casing is pulled out, the gravel bed steel casing needs to be rotated to enable the limiting blocks to be aligned with the via holes. The method is convenient to operate and transport.
本发明属于灌注桩成孔的技术领域，尤其涉及一种旋挖成孔灌注桩施工方法及系统。方法包括如下步骤：获取待施工地点的地质勘察信息，将多个砂砾层钢护筒子件和淤泥层钢护筒子件分别组装成砂砾层钢护筒和淤泥层钢护筒；砂砾层钢护筒的直径大于淤泥层钢护筒的直径；对砂砾层旋挖得到第一桩孔，向导向槽中插入滚动支撑件，对淤泥层旋挖得到第二桩孔，继续向第二桩孔下方旋挖得到第三桩孔；第一桩孔、第二桩孔和第三桩孔共同构成灌注桩孔；在所述灌注桩孔内放置钢筋笼后，往所述灌注桩内浇筑混凝土，先起拔砂砾层钢护筒，再起拔淤泥层钢护筒；起拔砂砾层钢护筒时，需旋转砂砾层钢护筒使得限位块与过孔对齐。本发明方法操作和运输方便。
