Pipe jacking working well soil body maintenance structure applying Larsen steel sheet piles and pipe jacking construction method of pipe jacking working well soil body maintenance structure
The invention discloses a pipe-jacking working well soil body maintenance structure applying Larsen steel sheet piles and a pipe-jacking construction method. The pipe-jacking working well soil body maintenance structure comprises at least two pipe-jacking working wells. The maintenance of each working well comprises a plurality of reinforced concrete fender posts and a plurality of Larsen steel sheet piles; a plurality of continuous Larsen steel sheet piles are adopted as end soil body enclosures on the face, used for penetrating in or out of a jacking pipe, of each jacking pipe working well; during pipe jacking, the positions, needing to be provided with a plurality of continuous Larsen steel sheet piles serving as end soil body enclosures, of each pipe jacking working well are positioned firstly, then construction grooves are dug out, and all corresponding Larsen steel sheet piles are inserted to serve as the end soil body enclosures; secondly, all Larsen steel sheet piles are driven one by one; thirdly, earthwork is excavated, and soil protection is backfilled; and finally, when the distance between the pipe jacking machine and the end soil body enclosure is 0.5 m, the corresponding Larsen steel sheet piles are pulled out. The problems that in existing pipe jacking construction, in the reinforced concrete chiseling process, a machine head cutter can be abraded, and time and economy are wasted are solved.
本发明公开了应用拉森钢板桩的顶管工作井土体维护结构及顶管工法，包括最少两个顶管工作井；每一工作井的维护均包括若干钢筋混凝土围护桩和若干拉森钢板桩；每一顶管工作井用于穿入或者穿出顶管的一面均采用若干连续的拉森钢板桩作为端头土体围护；顶管时，先对每一顶管工作井需要设置若干连续的拉森钢板桩作为端头土体围护的位置进行定位，然后挖出施工沟槽，插入相应的所有拉森钢板桩作为端头土体围护；其次，逐一打入所有拉森钢板桩；再次，开挖土方，回填土护；最后，当顶管机距离端头土体围护0.5m时，拔除相应的拉森钢板桩。本发明解决现有顶管施工中凿除钢筋混凝土的过程也会对机头刀具造成磨损，导致时间和经济的双重浪费的问题。
