Super-large-diameter lake-penetrating pipe jacking and withdrawing device and construction method thereof
The invention provides a super-large-diameter lake-penetrating pipe jacking and withdrawing device and a construction method thereof. A ring beam is arranged at a pipe jacking hole and is coaxial with a pipe joint, at least one reverse jacking jack is arranged on the two sides of the ring beam, a reaction frame is further arranged on one side of the ring beam, the telescopic ends of the reverse jacking jacks on the two sides are connected with the reaction frame, and a plurality of threaded pull rods are arranged on the reaction frame; one end of the threaded pull rod is connected with the tube push bench head, and the other end is connected with the counter-force frame. When the pipe is withdrawn, the stability of the stratum can be kept, the stratum collapse and the overlarge settlement of the earth surface are prevented, many problems of the withdrawing of the super-large-diameter jacking pipe can be solved, and meanwhile, the tunneling efficiency of the double jacking of the jacking pipe can also be improved.
本发明提供一种超大直径穿湖顶管退管装置及其施工方法，环梁设置在顶管洞口，且与管节同轴，环梁两侧设有至少一个反顶千金顶，环梁一侧还设有反力架，两侧的反顶千金顶伸缩端与反力架连接，反力架上设有多根螺纹拉杆，螺纹拉杆一端与顶管机机头连接，另一端与反力架连接。退管的同时能够保持地层的稳定，防止了地层塌陷以及地表出现过大的沉降，能够解决超大直径顶管回退的诸多问题，同时也能够提高顶管复顶的掘进效率。
