Problems solved by technology
[0003] The purpose of the present invention is to provide a shield tunneling construction method for special-shaped wells, which can solve the problem that the shield tunneling opening in special-shaped tunnels is too far away from the end wall or cannot be placed in conventional shield tunneling tunnels due to the size limitation of the tunnel tunnel. The starting bracket or reaction frame and the lack of starting bracket or reaction frame body in the actual starting construction caused poor rigidity of the starting structure

The present invention provides a construction method of the starting distribution of a different type of shield, including: S1) Putting the first starting platform and the second haircut, setting up the reaction frame installation slot, the first and second distribution platform eachIncluding two unilateral starting platforms set by the symmetrical tunnel axis, each unilateral starting table has horizontal installation surface and installation slope; S2) Installed the symmetrical tunnel axis on the first and second hair platform on the first and second hair platformsInstall two parallel starting guide rails; S3) assemble the shield machine in the alien well and set the shield machine to the end of the starting guide track at the end of the starting cave door; S4) fixed the reaction force in the reaction frame installation slot.Sermer; S5) The horizontal installation surface of the first and second hair platforms on the first distribution platform and the secondary distribution platform have multiple shields moved pier; S6) Fixed top push device between the shield movement pier and the shield machine; S7) Push the shield machine movement through the push device; S8) Break the starting door.The stability and rigidity of the starting structure in this method are better, the manufacturing cycle is short, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a shield tunneling construction method for special-shaped wells. Background technique [0002] In the shield construction of the tunnel, the shield tunneling in the prior art adopts the steel support frame structure of the double reaction force frame and the launching structure of the launching bracket to realize the shield launching, specifically, between the launching shaft and the terminal Set up a starting bracket of steel structure between the walls, erect the shield body of the shield machine on the starting bracket, and then install a double reaction frame on the ground of the launching shaft at the tail of the shield body of the shield machine At the same time, 12 horizontal supporting steel pipes are installed between the construction surface to be excavated and the double reaction frame. Due to the limitation of the size of the launch shaft, the launch brac...
