Static pressure inclined PRC pipe pile support construction method
The invention discloses a static pressure inclined PRC pipe pile support construction method which comprises the following steps: surveying, setting out and positioning: establishing a plane control network and an elevation control network by adopting a total station, compiling a pile number and extracting a pile position coordinate, measuring a pile point terrace elevation by adopting RTK (Real Time Kinematic) matched with a level gauge, calculating an actual setting out coordinate or extracting the actual setting out coordinate by adopting CAD (Computer Aided Design) offset, and setting out a pile position; a pile machine set is installed in place, debugging is conducted, a pile machine pressure gauge is calibrated, a variable-amplitude oil cylinder and a telescopic oil cylinder are checked, an angle displayer is calibrated, a pile machine long ship needs to be parallel to the pile row axis, and it is guaranteed that the Y-direction deviation of the pile position is within 1 degree. Concrete can be saved by the aid of the prefabricated pipe piles, construction waste can be reduced, good environment-friendly effects and economical efficiency can be realized, and noise can be effectively reduced by the aid of static pressure pile sinking.
本发明公开了静压倾斜PRC管桩支护施工工法，包括如下步骤：测量放线定位：采用全站仪建立平面控制网和高程控制网，编制桩号并提取桩位坐标，采用RTK配合水准仪测量桩点地坪标高，计算实际放线坐标或采用CAD偏移提取实际放线坐标，施放桩位，桩位用钢签定位，设备就位：桩机组装好就位，并进行调试，校定桩机压力表，检查变幅油缸、伸缩油缸和校定角度显示器，桩机长船应与排桩轴线平行，保证桩位Y方向偏差在1°以内，本静压倾斜PRC管桩支护施工工法采用直斜桩可提高安全可靠性，并且采用预制管桩可节约混凝土，减少建筑垃圾，具有较好的环保效果和经济性，同时采用静压沉桩可有效减小噪音。
