Combined cast-in-situ bored pile double pile casing and construction method thereof
The invention relates to a combined cast-in-situ bored pile double pile casing and a construction method thereof. The double pile casing comprises an outer pile casing body and an inner pile casing body, wherein an inner locking opening plate is arranged on the inner side of the outer pile casing body in the axial direction of the outer pile casing body in a full-length mode, an outer locking opening plate which is used for being meshed with the inner locking opening plate is arranged on the outer side of the inner pile casing body in the axial direction of the inner pile casing body in a full-length mode, when the inner locking opening plate and the outer locking opening plate are in a meshed state, the inner pile casing body and the outer pile casing body are relatively fixed in the horizontal direction, and the axis of the inner pile casing body coincides with the axis of the outer pile casing body. According to the combined cast-in-situ bored pile double pile casing and the construction method thereof, it is better guaranteed that the centers of the inner pile casing body and the outer pile casing body coincide, one-time accurate positioning of the double pile casing is achieved, the embedding precision of the double pile casing is improved, the construction process is simplified, the construction period is shortened, and the construction quality is guaranteed.
本发明涉及一种组合式钻孔灌注桩双护筒及其施工方法，该双护筒包括：外护筒，所述外护筒的内侧沿所述外护筒的轴向通长设有内锁口板；内护筒，所述内护筒的外侧沿所述内护筒的轴向通长设有供所述内锁口板咬合的外锁口板，在所述内锁口板与所述外锁口板咬合状态时，所述内护筒与所述外护筒在水平方向上相对固定，且所述内护筒的轴线与所述外护筒的轴线重合。本发明更好地保证了内、外护筒的中心重合，实现对双护筒的一次定位准确，提高双护筒埋设的精度，简化了施工流程，节约了施工工期，保证了施工质量。
