Construction process of prestressed concrete pipe pile
The invention relates to the technical field of concrete products, and particularly relates to a construction process of a prestressed concrete pipe pile. The prestressed concrete pipe pile is manufactured by adopting a centrifugal forming method and comprises a cylindrical pile body, an end plate and a steel hoop, wherein the pile body is prepared from the following components in parts by mass: 100-200 parts of water, 200-300 parts of cement, 300-400 parts of river sand, 10-30 parts of a water reducing agent, 100-200 parts of pebbles and 20-30 parts of an early strength agent, the water-binder ratio is 0.24, and the sand ratio is 35%. According to the construction process of the prestressed concrete pipe pile, the manufactured prestressed concrete pipe pile is high in strength, high in use safety coefficient, long in service life, simple and easy-to-obtain in raw materials and low in production and construction cost.
本发明涉及混凝土制品技术领域，尤其是一种预应力混凝土管桩的施工工艺，所述预应力混凝土管桩采用离心成型法制成，包括圆筒形桩身、端头板和钢套箍，所述桩身的质量份组成如下：水100‑200份、水泥200‑300份、河砂300‑400份、减水剂10‑30份、石子100‑200份、早强剂20‑30份，水胶比为0.24，砂率为35%；本发明中的预应力混凝土管桩的施工工艺，制得的预应力混凝土管桩，强度高，使用安全系数高，使用年限久，原料简单易得，生产和施工成本低。
