Water proof structure and interlayer guarded drainage construction are built, it is characterized in that: interlayer guarded drainage construction includes being set to pipe-plate lining and two
Circumferential blind pipe, longitudinal blind pipe between secondary lining cutting, between pipe-plate lining and tunnel bottom filled layer, and it is set to tunnel bottom filled layer cross
To longitudinal ditch of two sides；The circumferential blind pipe of longitudinally spaced setting is located at outside the circumferential splicing seams of pipe-plate lining, circumferentially between
It is located at outside the longitudinal spliced seam of pipe-plate lining every longitudinal blind pipe of setting, the both ends of longitudinal blind pipe and adjacent two circumferential blind pipe connect
Logical, longitudinal ditch is accessed in the lower end of circumferential blind pipe.
The pipe-plate lining water proof structure includes that circumferentially splicing seams and longitudinal spliced seam are placed in adjacent section of jurisdiction Mosaic face
Between elastic sealing gasket, hydro-expansive rubber item and filleting, be embedded on the Mosaic face of section of jurisdiction in corresponding groove；Splice in section of jurisdiction
On face, filleting closes on section of jurisdiction inner surface, and elastic sealing gasket leans on section of jurisdiction outer surface side, and hydro-expansive rubber item is located at filleting, elasticity
Between gasket.
The utility model has the beneficial effects that constituting guarded drainage body by pipe-plate lining water proof structure and interlayer guarded drainage
System can effectively improve the guarded drainage performance that band two serves as a contrast shield tunnel, realize the scientific and systematization of waterproof and drainage design.
