Precast concrete pipe pile structure and pile cutting method thereof during uplift pile manufacturing
The invention relates to a precast concrete pipe pile structure and a pile cutting method thereof during uplift pile manufacturing. The pipe pile structure comprises a precast concrete pipe pile (1), wherein the precast concrete pipe pile (1) is in a hollow cylinder shape as a whole, a through hole (2) is formed in the center of the precast concrete pipe pile (1) in the vertical direction, a hydraulic jack (3) is arranged in the through hole (2), and the outer surface of the precast concrete pipe pile (1) is sleeved with a steel hoop (4). According to the precast concrete pipe pile structure and the pile cutting method thereof during uplift pile manufacturing, a pile body is not prone to cracking within the effective pre-pressing stress range, prestressed steel bars are well protected, the pile body strength is high, and the manufacturing cost is low.
本发明涉及一种预制混凝土管桩结构及其做抗拔桩时的截桩方法，所述管桩结构包括预制混凝土管桩(1)，所述预制混凝土管桩(1)整体呈中空圆柱状，所述预制混凝土管桩(1)中心沿竖向开设有通孔(2)，所述通孔(2)内设置有液压千斤顶(3)，所述预制混凝土管桩(1)外表面套装有钢抱箍(4)。本发明一种预制混凝土管桩结构及其做抗拔桩时的截桩方法，其在有效预压应力范围内桩身不容易出现裂缝，对预应力钢筋保护较好，桩身强度高，且造价低。
