Deepwater cast-in-situ bored pile construction method
The invention relates to a deepwater cast-in-situ bored pile construction method, and belongs to the technical field of engineering construction, and the deepwater cast-in-situ bored pile construction method comprises the following steps: pile transportation: utilizing a construction ship to drag a split type pile casing structure floating on the water surface to a to-be-constructed position; pile erecting is conducted, specifically, one end of the split type pile casing structure is rotated downwards in the vertical plane till the split type pile casing structure is vertically arranged in water; piling is conducted, specifically, the permanent pile casing of the split type pile casing structure is inserted into a water bottom soil layer in the vertical direction through an impact hammer installed on a construction ship; concrete is poured, specifically, concrete is poured into a pouring cavity in the split type pile casing structure to form a concrete pile; and the detachable pile casing is detached, specifically, the detachable pile casing is separated from the permanent pile casing, the detachable pile casing is made to rotate upwards in the vertical plane till the detachable pile casing floats on the water surface, and the detachable pile casing is recycled. The construction method of the deepwater cast-in-situ bored pile is short in construction period, the detachable pile casing can be recycled, and the construction cost is low.
本发明涉及一种深水钻孔灌注桩施工方法，属于工程施工技术领域，其中该深水钻孔灌注桩施工方法包括以下步骤：运桩：利用施工船舶将漂浮在水面上的分体式护筒结构拖运到待施工位置；立桩：将分体式护筒结构的一端在竖直平面内向下转动，直至分体式护筒结构竖直设于水中；打桩：利用安装在施工船舶的冲击锤将分体式护筒结构的永久性护筒沿竖直方向插入水底土层中；浇筑混凝土：向分体式护筒结构内部的浇筑腔中浇筑混凝土，以形成混凝土桩；拆除可拆除护筒：将可拆除护筒与永久护筒分离，使可拆除护筒在竖直平面内向上转动直至漂浮于水面上，以将可拆除护筒回收利用。该深水钻孔灌注桩施工方法施工周期短、可拆除护筒可循环利用并且施工成本低。
