Mass defect), a large amount of percolating waters will occur in Tunnel, have a strong impact on traffic safety；At present, for the place of Tunnel Water Leakage
The method for controlling method generally use " draining of raggle pipe laying ", i.e., chisel groove along the secondary lining surface of percolating water, and embedment is half-sectional
Plastic tube, introduce the water into gutter；Using the method for " draining of raggle pipe laying ", there are the following problems：First, structure is damaged
Wound, reduce bearing capacity, because two lining structure thickness are generally in the range of 35~55cm, and the depth of fluting normally close to 8~
15cm, close to the 20~27% of structural thickness, therefore have an impact to structural bearing；Second, construction is relatively difficult, time-consuming bothersome, right
In the situation that reinforcing bar is set in two lining structures, because thickness of protection tier is typically in 4cm or so, therefore will necessarily be run into during raggle
Thickly dotted reinforcing bar, the concrete cut between reinforcing bar is not easy, then to allow exposed reinforcing bar to handle the sky to enough pipe layings
Between outside scope, be even more difficulty；3rd, unfavorable pipe is supported, and finally concrete enclosing is used after half-sectional pipe is put into groove, until with lining
It is equal to build surface, once drainage pipeline is blocked again, raggle pipe laying structure must be opened, constructed again, for operation tunnel
To complete to repair in a short time extremely difficult.
