Pile head plugging process for PHC prestressed pipe pile
The invention relates to a PHC prestressed pipe pile head plugging process which comprises the following steps: step 1, surveying and setting out a construction site, and determining the position of a guide hole; 2, the inner wall of the precast pile is injected and filled with a polyurethane foaming agent till the inner space of the precast pile is fully filled, and water is sprayed or sprinkled to the inner wall of the precast pile during injection and filling; 3, the pile tip piece and the precast pile are welded and fixed; 4, hole guiding is conducted on the hole guiding position; and 5, the precast pile is pressed, and the precast pile is pressed into the hole from the guide hole position. The anti-seepage effect of the pipe pile can be improved.
本申请涉及一种PHC预应力管桩桩头封堵工艺，包括：步骤1：对施工场地测量放样，确定引孔位置；步骤2：对预制桩的内壁喷射填充聚氨酯发泡剂，直至将预制桩的内部空间填充饱满，喷射填充时对预制桩的内壁进行喷水或洒水；步骤3：将桩尖件与预制桩焊接固定；步骤4：对引孔位置进行引孔；步骤5：对预制桩进行压桩，将预制桩从引孔位置压入孔内。本申请可改善管桩的防渗效果。
