Underwater cast-in-situ bored pile and construction technology
The invention relates to an underwater cast-in-situ bored pile and a construction technology, and belongs to the technical field of special cast-in-situ bored piles, the underwater cast-in-situ bored pile comprises a steel casing, the steel casing comprises a bottom casing, an inner casing and an outer casing connected with the inner casing in a sleeving mode, the inner casing is fixed to one end of the bottom casing, and the outer casing is fixed to the other end of the bottom casing; the outer pile casing comprises a first outer pile casing, a second outer pile casing and a third outer pile casing which are sequentially arranged from top to bottom, the number of the second outer pile casing is at least one, a first flange plate is fixed to the outer wall, away from the second outer pile casing, of the third outer pile casing, a second flange plate is fixed to the outer wall of the bottom pile casing, and the second flange plate is fixed to the outer wall of the bottom pile casing. The first flange plate and the second flange plate are fixed through bolts; the top of the first outer pile casing is flush with the top of the inner pile casing, a fixing assembly is arranged at the top of the first outer pile casing, and the first outer pile casing and the inner pile casing are fixed through the fixing assembly. The device has the effect that part of the steel casing can be conveniently recycled and reused.
本申请涉及一种水下钻孔灌注桩及施工工艺，属于专钻孔灌注桩的技术领域，其包括钢护筒，所述钢护筒包括底部护筒、内护筒和与内护筒套接的外护筒，述内护筒固定在所述底部护筒的一端，所述外护筒包括从上到下依次设置的第一外护筒、第二外护筒和第三外护筒，所述第二外护筒的数量至少为一个，所述第三外护筒远离第二外护筒的外壁上固定有第一法兰盘，所述底部护筒的外壁上固定有第二法兰盘，所述第一法兰盘和所述第二法兰盘通过螺栓固定；所述第一外护筒的顶部与所述内护筒的顶部平齐，所述第一外护筒顶部设置有固定组件，所述第一外护筒与内护筒通过固定组件固定。本申请具有便于对部分钢护筒进行回收和重复利用的效果。
