Static pressure pile splicing method
The invention relates to the technical field of constructional engineering, in particular to a static pressure pile splicing method which comprises the following steps: pile splicing and welding: when a pile head of a lower-section pile is away from the ground by a preset distance, pile pressing is stopped, pile splicing is welded, and the pile splicing welding process is controlled within preset time; wherein the pile welding and splicing comprises the following steps of: before the pile welding and splicing, cleaning the welding surfaces of two sections of pipe piles; during pile splicing, the axes of the upper pile section and the lower pile section are consistent, and the dislocation deviation is smaller than a preset dislocation deviation value; during pile splicing, a guide hoop is installed on the pile head of the lower pile section, the upper pile section is guided to be in place, and the welding faces of the upper pile section and the lower pile section are tightly attached; the butt-joint pile is inspected, and if the butt-joint pile is inspected to be qualified, positioning spot welding is conducted; the guide hoop is dismantled, and symmetrical layered welding is carried out; windproof treatment is carried out during welding; and after welding is completed, quality inspection is conducted on welding, and if inspection is qualified, beating is conducted after welding cooling is conducted for preset time. According to the scheme, risks affecting the welding quality are controlled in the welding process, and the welding quality can be improved.
本发明涉及建筑工程技术领域，具体为静压桩接桩方法，包括：接桩与焊接：当下节桩的桩头距地面预设距离时，停止压桩，进行焊接接桩，且焊接接桩过程控制在预设时间内；其中焊接接桩，包括：焊接接桩前，对两节管桩的焊面进行清洁；接桩时使上节桩与下节桩的轴线一致，错位偏差小于预设错位偏差值；在接桩时在下节桩的桩头上安装导向箍，引导上节桩就位，且上下节桩焊面紧密贴合；对接桩进行检查，若检查合格，则进行定位点焊；拆除导向箍，进行对称分层施焊；焊接时进行防风处理；焊接完成后，对焊接进行质量检查，若检查合格，焊接冷却预设时间后进行施打。本方案在焊接过程中对影响焊接质量的风险进行管控，能提高焊接质量。
