Long working life.Number of patent application 201310189977.8 proposes a kind of cast side of bridge expanssion joint elastic water-proofing material
Method, does end liner from antiseized poly-bag, first inflation filling, but after pouring material solidification, deflation is removed the method for bag and completes to pour work,
Certain volume is had after being effectively reduced the use of foamed material, but the antiseized poly-bag inflation of the method proposition, after deflation
Can have vacant interval between bridge and the elastomeric material that pours, it is impossible to realize the combination for pouring elastomer and bridge interface, and
And the easy explosion of poly-bag after inflating, service life is limited, and the adhesive tape after explosion is it is also possible to construction failure can be caused.Based on above-mentioned
