Above-mentioned technical problem is solved the technical solution adopted is that including the following steps：The outer curtain note of S1, Tunnel
Slurry；S2, Tunnel；S3, Tunnel Second Lining；S4, tunnel waterproofing layer；The lining cutting three times of S5, tunnel.
The outer curtain-grouting of the Tunnel of the present invention is included in before tunnel excavation carries out advanced curtain to tunnel tunnel face
Curtain slip casting forms 3~5m ejection for water plugging fixing collars behind in Tunnel.
The Tunnel of the present invention includes loopful setting steel arch-shelf, is laid with bar-mat reinforcement, it is early that C25 is sprayed in tunneling boring supporting
Reinforced concrete adds micro-expanding agent in the concrete.
The Tunnel Second Lining of the present invention is included in mixed using impervious reinforcing bar after the completion of supplement slip casting outside Tunnel
Solidifying clay model building lining construction.
After the tunnel waterproofing layer of the present invention is included in completion Tunnel Second Lining and form removal, repairing leveling Tunnel Second Lining
Concrete surface, installs waterproof layer after smooth, cleaning, the waterproof layer is to overlay waterproof roll.
The present invention's overlays waterproof roll using asphaltic base polyester blank or resinae homogeneous polymer membranes or resin
Class composite high-molecular waterproof roll；The asphaltic base polyester blank overlays waterproof roll thickness and is at least 4mm, and resinae homogeneous is high
Molecule waterproof sheet or resinae composite high-molecular waterproof sheet overlay waterproof roll thickness and are at least 1.5mm.
The tunnel of the present invention is constructed after the completion of lining cutting is included in waterproof layer using reinforced concrete lining layer three times, seepage-resistant grade
For P10.
The present invention tunnel three times lining cutting when in arch along tunnel radial direction built-in slip casting pipe, the built-in slip casting pipe stretches into
Lining cutting three times, the longitudinal pitch between adjacent built-in slip casting pipe are 2~3m.
The present invention tunnel three times lining cutting when circular construction joint in rubber fastening band is installed, the rubber fastening band is
Middle rubber fastening band with grouting tube is equipped with 5mm thickness galvanized steel plain sheet waterstops in longitudinal construction joint.
The present invention has the following advantages compared with the prior art：
1, compared to existing two layers of waterproofing design, the outer curtain-grouting of Tunnel of the present invention forms ejection for water plugging and adds
Gu Quan, grouting reinforced region are first of waterproof construction in tunnel and main waterproof construction, make tunnel structure not easy to leak, are prevented
Water effect is more preferable.
2, waterproof layer is installed after the completion of two lining concreting, reduces later stage structural leakage water process and safeguards risk.
3, longitudinal construction joint is formed between inverted arch and arch wall, and 5mm thickness galvanized steel plain sheet waterstops are installed in longitudinal construction joint
1, enhancing structure waterproof effect.
