Waterproof structure of high speed railway ballastless concrete bridge continuous concrete carriageway plate system
The invention discloses a waterproof structure of a high speed railway ballastless concrete bridge continuous concrete carriageway plate system, replaces a waterproof method which adopts a polyurea material on a bridge deck originally, solves the problem of negligence of preventing rainwater hazards at horizontal boundary planes and vertical boundary planes between continuous concrete carriageway plate system components in the prior art, and effectively controls the humidity strain of a concrete carriageway plate and damage of wet expansion stress of a concrete base plate due to long-time rainwater adsorption of the boundary planes. The waterproof structure has unique reliability and is economic, and the maintenance cost is greatly reduced. More importantly, the operation safety of the high speed railway ballastless concrete bridge continuous concrete carriageway plate system is improved, and the service life of the high speed railway ballastless concrete bridge continuous concrete carriageway plate system is prolonged.
