Large-diameter pit type static pressure slurry leakage steel pipe pile and construction technology thereof
The invention discloses a large-diameter pit type static pressure slurry leakage steel pipe pile and a construction technology thereof, and relates to the technical field of constructional engineering construction.The large-diameter pit type static pressure slurry leakage steel pipe pile comprises a first steel pipe pile body, a second steel pipe pile body is fixed to the upper end of the first steel pipe pile body, and a conical pile tip is fixed to the lower end of the first steel pipe pile body; a plurality of evenly-distributed through holes are formed in the outer wall of the first steel pipe pile body, the outer wall of the second steel pipe pile body is in a smooth closed shape, and an underpinning pile cap is arranged at the upper end of the second steel pipe pile body. After the construction technology is completed, cement paste is poured into the steel pipe pile at the drilling section of the lower section pile body and leaks to gaps around the pile body through the through holes, the cement paste wraps the lower section steel pipe pile, the friction force between the steel pipe pile and a soil body is increased, and the bearing capacity of the static pressure pile can be increased by continuously pouring concrete into the steel pipe pile.
本发明公开了一种大直径坑式静压漏浆钢管桩及其施工工艺，涉及建筑工程施工技术领域，包括第一钢管桩桩身，所述第一钢管桩桩身的上端固定有第二钢管桩桩身，所述第一钢管桩桩身额下端固定有圆锥桩尖，所述第一钢管桩桩身的外壁开设有多个均匀分布的通孔，所述第二钢管桩桩身的外壁呈光滑密闭状，所述第二钢管桩桩身的上端设置有托换桩帽；施工工艺完成后，该静压钢管桩在下段桩身钻孔段，通过钢管桩内灌注水泥浆并通过通孔漏出至桩身四周空隙，水泥浆包裹下段钢管桩，增大钢管桩与土体的摩擦力，通过继续在钢管桩内灌注混凝土可增大静压桩的承载力。
