Draiage-proof composite rubber-plastic slab for tunnel

The utility model relates to a drainage-proof composite rubber-plastic plate for a tunnel, which comprises a framework layer 1 and a water proof layer 2, wherein, the framework later 1 is a non-woven fabric layer. The water proof layer 2 compounded on one side of the framework layer 1 is a rubber-plastic water proof layer plate. The utility model has the advantages of good water drainage proof effect, aging resistance, penetration resistance and good acid-alkali resistant performance. The drainage-proof composite rubber-plastic plate for a tunnel can be preformed into large pieces of soft sectional materials in the factory, and thus the randomness is good, the construction is convenient and the manufacturing process is simple. The drainage-proof composite rubber-plastic plate for a tunnel can be nailed to be hung or hung, which enables the construction progress to be accelerated and the integrate cost to be reduced. The utility model is mainly used for drainage-proof projects of roads, railways, tunnels, underground projects, etc.
