Device for rapidly pulling out waste piles in shield construction crossing area
The invention discloses a device for rapidly pulling out waste piles in a shield construction crossing area. The device comprises a pile clamping device, a base is arranged at the bottom of the pile clamping device, a hydraulic cylinder is arranged at the bottom of the base, an auxiliary mechanism is further arranged at the bottom of the base, the auxiliary mechanism comprises a truss, the truss is fixed to the base through a hydraulic column, and an annular rail is arranged on the truss; an annular gear ring is rotationally connected in the annular track, a plurality of gears are engaged in the annular gear ring, rotating shafts are fixed to the bottoms of the gears and penetrate through the truss to be connected with the angle steel, hydraulic push rods are arranged on the outer side of the annular gear ring, and the telescopic ends of the hydraulic push rods are hinged to the annular gear ring; by arranging the auxiliary device, before the pile clamping device is matched with the hydraulic cylinder to pull out the waste pile, the side face, making contact with the land, of the waste pile is treated, the gap between the waste pile and the land soil is enlarged, the friction resistance of the land soil to the waste pile is reduced, and therefore the follow-up pile pulling action is facilitated.
本发明公开了一种盾构施工穿越区快速拔除废弃桩的装置，包括夹桩器，夹桩器的底部设置有底座，底座底部布置有液压缸，底座底部还设置有辅助机构，辅助机构包括桁架，桁架通过液压柱与底座固定，桁架上设置有环形轨道；环形轨道内转动连接着环形齿圈，环形齿圈的内部啮合有多个齿轮，齿轮的底部固定有转轴，转轴贯穿桁架与角钢连接，环形齿圈的外侧设置有液压推杆，液压推杆的伸缩端与环形齿圈铰接；本申请通过设置辅助装置，在夹桩器与液压缸配合对废弃桩进行拔除之前，对废弃桩与土地接触的侧面进行处理，扩大废弃桩与土地土壤之间的间隙，减少土地土壤对废弃桩的摩擦阻力，从而方便后续的拔桩动作。
