Concrete pile casing for drilling construction adjacent to subway cast-in-situ bored pile and using method
The invention relates to a concrete pile casing for drilling construction adjacent to a subway cast-in-situ bored pile and a using method. The concrete pile casing comprises a groove-shaped concrete pile casing body, reserved bolt holes and an embedded reinforcing mesh. The groove-shaped concrete pile casing comprises a pile casing body, an upper beam and a lower beam, and a plurality of reserved bolt holes are formed in the upper beam and the lower beam in the circumferential direction. The cast-in-place pile has the beneficial effects that the reinforcing mesh is pre-embedded in the inner wall of the concrete pile casing, after concrete is poured, the concrete, the pre-embedded reinforcing mesh and the groove-shaped concrete pile casing form a whole, the side, close to soil, of the groove-shaped concrete pile casing is a rough surface, and it is guaranteed that the bearing capacity of the cast-in-place pile conforms to a design value; the concrete pile casing does not need to be pulled out, and the problem that a traditional steel pile casing is difficult to pull out is solved; the concrete pile casing is of a prefabricated structure, bolt holes of the same specification are formed in the upper beam and the lower beam, the adjacent concrete pile casings are connected through bolts, operation is easy, construction is convenient, and time and labor are saved.
本发明涉及一种紧邻地铁钻孔灌注桩钻孔施工的混凝土护筒及使用方法，包括凹槽形混凝土护筒、预留螺栓孔和预埋钢筋网；凹槽形混凝土护筒包括护筒、上梁和下梁，上梁和下梁环向上设有数个预留螺栓孔。本发明的有益效果是：混凝土护筒内壁预埋有钢筋网，在浇筑混凝土后，混凝土、预埋钢筋网和凹槽形混凝土护筒形成整体，且凹槽形混凝土护筒近土侧为粗糙表面，保证灌注桩承载力与设计值相符；本发明的混凝土护筒无需拔出，避免了传统钢护筒拔出困难的问题；混凝土护筒为预制结构，上梁与下梁处均设有规格相同的螺栓孔，相邻混凝土护筒间通过螺栓相互连接，操作简单，施工方便，省时省力。
