Gansu tunnel inflatable balloon production needs a few days, the iron tunnel inflatable balloon 10 innings, the tunnel should be simple ditch airbag protection products for high-speed operation, lightweight, easy to use, with good anti-aging properties, wide application and can be reused many times, It can greatly reduce costs and improve construction into the structures, the use balloon mold, which is 25% lighter weight than non-prestressed solid component for the construction of a tunnel construction site in an inflatable balloon 10 Railway Bureau, the tunnel ditch airbag protection to high-speed use general case, a production takes three days hollow balloon mold of time, which then rolled rubber blanks in a large flat vulcanizing machine sulfide into the hole, set to make the hole takes two days, and then began a 24-hour closed water breath test balloon factory will be no quality problems, ensure that there is a problem of the balloon will appear in the workshop, will not appear on the site. tunnel inflatable balloon 10 innings of iron, ditches airbag protection to high-speed tunnel with Dalian Wang to visit our factory hollow board balloon mold than the length of one meter long slab, the better the release, if enough skilled construction workers technology, each hollow balloon mold can turnover of more than 60 times. Each balloon rubber are two layer of hot-rolled vulcanized rubber layer of anti-Raab step molding, rubber thickness is 3.2mm, anti-pull-out strength of the intermediate Rab greater than 12MPA, each balloon before it leaves the factory to do 24 hours of closed water breath test to the factory to ensure that goods can be used to complete the tunnel construction site iron inflatable balloon 10 innings, airbag protection to high-speed tunnel ditch with hollow balloon mold is a cylindrical rubber bag in the production of circular inflatable mandrel, the general length is 0.5 meters longer than the slab. Each circular inflatable mandrel made when placed inside reinforcement, use of anti-distortion technology to ensure the hollow member into the hole made accurate inner hollow plate airbag module carried out for 24 hours breath test before shipment. produced slab size is accurate to ensure that in the course of deformation.
