Anti-sedimentation precast pile for soft soil foundation
The invention discloses a soft soil foundation anti-sedimentation precast pile which comprises a pipe pile, a round steel plate is fixedly installed in the pipe pile, anchoring steel bars are welded to the four corners of the top of the round steel plate, the tops of the anchoring steel bars extend to the position above the pipe pile, and stirrups are installed on the four anchoring steel bars at equal intervals in the vertical direction; micro-expansion concrete poured in the tubular pile is arranged above the round steel plate, the top of the tubular pile is provided with crossed steel bars, the four anchoring steel bars are sleeved with the crossed steel bars, a structural plate is poured on the crossed steel bars, and the periphery of the structural plate extends out of the tubular pile. The structural plate is arranged on the upper portion of the pipe pile, so that ground subsidence can be prevented, the structural plate can be arranged at a certain depth below the soil layer according to needs, cost control over concrete and steel bars is achieved, ground subsidence which cannot be predicted in the later period is avoided, and the cost is better than that of a conventional subsidence prevention measure.
本发明公开了一种软土地基防沉降预制桩，包括管桩，所述管桩内固定安装有圆钢板，所述圆钢板的顶部四角位置均焊接有锚固钢筋，且锚固钢筋的顶部延伸至管桩的上方，四个锚固钢筋上沿竖直方向等距离间隔安装有箍筋，所述圆钢板的上方设有浇筑在管桩内的微膨胀混凝土，所述管桩的顶部设置有交叉钢筋，且交叉钢筋套接在四个锚固钢筋上，所述交叉钢筋上浇筑有结构板，且结构板的四周延伸至管桩外。本发明采用管桩上部设置结构板，这样能实现防止地面沉降，结构板可以根据需要置于土层下一定深度，实现混凝土及钢筋的成本控制，避免后期无法预测的地面沉降，比常规的防止沉降措施成本更优。
