Piece is at this time supported section of jurisdiction using certain auxiliary device, prevents and topple over；Vault section of jurisdiction is finally assembled, is needed simultaneously
Guarantee the coupling at the top of vault section of jurisdiction and left and right abutment wall section of jurisdiction；Complete the tunnel duct piece assembly of the first pipeline section；
C, in the first pipeline section tail portion welding metal spring plate, the assembly in the second pipeline section assembled tunnel is carried out, after the assembly is completed by this
The unwelded end of medal spring plate and the second pipeline section head are welded, and the laying of resiliency deformable member is completed；
D, carry out automatically reseting between the first pipeline section and the second pipeline section the installation of key；
E, repeating A-D step can be completed the continuous propulsion in tunnel, until passing through fault belt.
10. construction method as claimed in claim 9, which is characterized in that in stepb, first with low temperature gas when assembling section of jurisdiction
Stream reduces alloy temperature, retracted configuration when it being made to restore low temperature；After the assembly is completed to adjacent tubes piece, make alloy with unheated air
Temperature restores room temperature, and shape restores swelling state when room temperature；Just adjacent section of jurisdiction wedge-shaped impression is generated when alloy expansion
Vertical extrusion stress, so that Wedge-shape connector is fixed.
