Flexible joint sealing method for expansion joint of concrete faced rockfill dam in cold region
The invention relates to a flexible joint sealing method for an expansion joint of a concrete faced rockfill dam in a cold region, and belongs to a processing method for the expansion joint of the hydraulic concrete faced rockfill dam in the cold region. The flexible joint sealing method comprises the steps that a concrete face is constructed through a drawing die method, an A-type interface agent or a B-type interface agent coats the side walls of a space, filled with a compound joint material, of the expansion joint in a painting mode, then rubber bars are placed into the conical surface of the space filled with the compound joint material, a constraint rebar net and a steel wire net are symmetrically connected to embedded rebars on the two sides, a formwork is pressed, and the stirred compound joint material is poured into the space filled with the compound joint material. The flexible joint sealing method has the advantages that the anti-freezing performance of the joint material in water is excellent, the effect of resisting freezing and melting circulation is good, the anti-aging performance of the material is good, and the problems that the durability of the concrete faced rockfill dam in the cold region is poor, and ice tearing damage exists are solved.
