Pile splicing method for PHC tubular piles in reclamation area
The invention relates to a pile splicing method for a PHC tubular pile in a reclamation area. The pile splicing method comprises the following steps that firstly, a concrete circular pile casing is prefabricated; secondly, a circular foundation pit is excavated with the PHC pipe pile as the center; thirdly, the concrete circular pile casing is placed in the foundation pit, and the concrete circular pile casing and the PHC pipe pile are concentrically arranged; step 4, backfilling the foundation pit outside the concrete circular pile casing; fifthly, after water in the concrete circular pile casing is discharged, a cylinder bottom concrete layer with the preset thickness is poured at the bottom in the concrete circular pile casing immediately; sixthly, after the cylinder bottom concrete layer reaches the preset strength, the pile core reinforcement cage and the pile top and bearing platform connecting reinforcement cage are bound; and seventhly, pile top core filling concrete and pile splicing concrete are poured. According to the pile splicing method for the PHC pipe pile in the reclamation area, the pile top of the PHC pipe pile in the reclamation area is spliced through the precast concrete circular pile casing, a formwork does not need to be erected, the precipitation difficulty is reduced, field operation is convenient, construction is easy, the construction cost can be saved, and the construction efficiency is improved.
本发明涉及一种填海区PHC管桩接桩方法，其包括如下步骤：步骤一、预制混凝土圆护筒；步骤二、以PHC管桩为中心开挖圆形基坑；步骤三、将混凝土圆护筒放入基坑中，使混凝土圆护筒与PHC管桩同心设置；步骤四、将混凝土圆护筒外部的基坑进行回填；步骤五、将混凝土圆护筒内的水排出后，立即在混凝土圆护筒内的底部浇筑预设厚度的筒底混凝土层；步骤六、待筒底混凝土层达到预设强度后，绑扎桩芯钢筋笼和桩顶与承台连接钢筋笼；步骤七、浇筑桩顶填芯混凝土和接桩混凝土。本发明提供的填海区PHC管桩接桩方法，通过使用预制混凝土圆护筒对填海区PHC管桩桩顶进行接桩，无需支设模板，降低了降水难度，现场操作方便，容易施工，能够节约施工成本，提高施工效率。
