Pile head plugging equipment and plugging method for PHC prestressed concrete pipe pile
The invention relates to the technical field of pipe pile plugging, in particular to PHC prestressed concrete pipe pile head plugging equipment and method.The PHC prestressed concrete pipe pile head plugging equipment comprises a top plate covering the top of a pile head, a sealing ring is arranged on the lower surface of the top plate, and a plurality of push plates located on the inner ring of the sealing ring are evenly and slidably connected to the lower surface of the top plate in the circumferential direction; a control rod is rotatably connected to the center of the top plate, a support is rotatably connected to the lower end of the control rod, a plurality of pushing lead screws arranged in the radial direction are rotatably connected to the support, and the pushing lead screws are connected with the lower end of the control rod through bevel gear pairs. An operator rotates the control rod, the control rod drives all the pushing lead screws to rotate through the bevel gear pair, so that all the pushing plates are driven to move outwards, and the pushing plates open the sealing ring till the sealing ring abuts against the inner wall of the pile head to seal the inner wall of the pile head. And during later dismantling, as the top plate is located at the top of the pile head, the top plate cannot move downwards and is exposed on the pile head all the time, dismantling by operators is facilitated, and use is convenient.
本申请涉及管桩封堵的技术领域，尤其是涉及PHC预应力混凝土管桩桩头封堵设备及封堵方法，包括盖于桩头顶部的顶板，顶板下表面设有密封圈，顶板下表面周向均匀滑动连接有多个位于密封圈内圈的推板，顶板下表面径向滑动连接有若干夹板，顶板中心转动连接有控制杆，控制杆下端转动连接有支架，支架上转动连接有多个沿径向设置的推动丝杆，推动丝杆通过锥齿轮副与控制杆下端相连。操作人员转动控制杆，控制杆通过锥齿轮副带动所有推动丝杆转动，从而带动所有推板向外运动，推板将密封圈撑开，直至密封圈与桩头内壁抵触对桩头内壁进行密封。且后期拆除时，由于顶板位于桩头顶部，顶板无法下移始终暴漏于桩头上方便于操作人员拆除，使用方便。
