Large-diameter pipe withdrawing device and pipe withdrawing method
The invention relates to the technical field of underground pipeline construction, and provides a large-diameter pipe withdrawing device and method. In the large-diameter pipe withdrawing device, the machine head connecting part is connected to the interior of the machine head of the pipe jacking machine. The power jacking part is connected to a base guide rail of the working vertical shaft in a sliding mode. And one end of the traction piece is connected with the machine head connecting part. The other end of the traction piece penetrates through the pipe withdrawing pipe joints from the machine head of the pipe jacking machine, extends into the working vertical shaft and is connected with the power jacking part. The power device is used for driving the power jacking part to slide along the base guide rail so as to drive the traction piece to drag the machine head of the pipe jacking machine to extrude the pipe retreating pipe joints to be retreated into the working vertical shaft. Through the structural arrangement, the motive power device is reversely installed, so that the motive power device reversely pushes the motive power jacking part, and then the motive power jacking part drives the traction piece to drag all the pipe retreating pipe joints and the pipe jacking machine head out of the pipe retreating pipeline one by one through the machine head connecting part. The large-diameter pipe withdrawing device is relatively simple in structure and relatively convenient to construct.
本发明涉及地下管道建设技术领域，提供了一种大口径退管装置及退管方法。在大口径退管装置中，机头连接部连接至顶管机机头内部。动力顶压部滑动连接至工作竖井的基座导轨上。牵引件的一端与机头连接部连接。牵引件的另一端由顶管机机头穿过各退管管节延伸至工作竖井内并与动力顶压部连接。动力装置用于驱动动力顶压部沿着基座导轨滑动，以带动牵引件拖拽顶管机机头挤压各退管管节退管至工作竖井中。通过这种结构设置，反向安装原动力装置，使得该动力装置反向推动动力顶压部，进而，动力顶压部带动牵引件通过机头连接部将各退管管节及顶管机机头逐个拖拽退出退管管道。该大口径退管装置的结构相对简单，施工相对方便。
