More Information
Summary:The invention discloses a method for constructing a tunnel by utilizing a shield empty-pushing crossing mine method. Gravels are paved in advance on an empty-pushing section, thereby being short in construction period; the gravels are stacked and filled in front of a cutter, a counter force is provided when the shield is in a tunneling process, and duct pieces are not fixed by structural steel; most clearances between the duct pieces and rock are filled with the gravels, thereby reducing work load and promoting tunneling efficiency; enough counter force is supplied by a jack for splicing the duct pieces, a water-stopping bar is excellently pasted and a waterproof effect is excellent; the duct pieces can be filled and compacted in time, the duct pieces after being spliced cannot float upward, and damaged and over-loaded staggered slabs do not exist; the grout amount on the back of the duct pieces is reduced and the construction cost is saved; and the tunneling efficiency is greatly promoted, the production val
