Construction method of prestressed concrete pipe pile
The invention discloses a construction method of a prestressed concrete pipe pile, which comprises the following steps: S1, lofting and positioning: arranging an axis square grid by using a total station, positioning a pile position, punching the pile position by using a steel chisel, filling lime and inserting a steel rod at the depth of less than or equal to 180mm; s2, pile inserting is conducted, specifically, a pile machine is in place, the pipe pile is fixed through a lock and lifted through the pile machine, and the peripheries of a pile cap and a pile top are well protected by aligning a pile tip with the center of the pile position and slowly inserting the pile tip into the pile position. According to the construction method, the peripheries of the pile cap and the pile top are protected, so that the hoop is formed above the pile top, meanwhile, the strength of the concrete of the pipe pile is improved, the pipe pile cannot generate longitudinal cracks during construction, and the quality of the concrete pipe pile is ensured. The high-quality concrete pipe pile is resistant to hitting compared with concrete with serious internal segregation, and the hitting-resistant effect of the concrete pipe pile is improved through arrangement of the gravel concrete.
本发明公开了一种预应力混凝土管桩的施工方法，包括以下步骤：S1、放样定位：利用全站仪设置轴线方格网，对桩位进行定位，并通过钢钎对桩位进行打孔，同时灌入白灰并插入钢棍，深度≤180mm；S2、插桩：桩机就位，用锁具固定管桩，并通过桩机对管桩进行起吊，通过将桩尖与桩位中心对准并缓慢插入，将桩帽和桩顶四周做好防护。本发明中，通过在桩帽和桩顶四周做好防护，则使桩顶上方形成有套箍，同时，通过管桩混凝土强度的提高，则使管桩在进行施工时不会产生纵向裂缝的，而且通过确保混凝土管桩的质量，则使高质量的混凝土管桩比有严重内离析的混凝土耐打，而且通过碎石混凝土的设置，提高了混凝土管桩的耐打效果。
