Octagonal inflatable mandrel length 17 m octagonal inflatable mandrel double protection, octagonal bridge inflatable mandrel / rubber mandrel hollow army bridge rubber inflatable mandrel bridge Profile bridge rubber inflatable mandrel bridge panel is also called balloon mold, deck inflatable core mold, precast hollow inflatable mandrel, bridges inflatable rubber mandrel, balloon mold, hollow capsules, hollow plastic core. The use of natural rubber and anti-Raab hot vulcanization molding, the mold is one of the best products into the hole and tunnel bridge engineering project, which belongs to the column, the cross section has a variety of models, rectangular, octagonal, a variety of shapes oval, circular, crown, there are inverted trapezoid, according to the construction design drawings made units corresponding cylinder. Military rubber mandrel bridge advantage of: (1) inflatable rubber mandrel process, make the whole plate girder precast construction progress greatly accelerated. (2) and one-time investment of wooden model comparison, inflatable mold turnaround for multiple use, and construction is simple and convenient, saving feed costs, the economic benefit. (3) through a rigorous process control mandrel construction, precast hollow quality issues can be further guaranteed.
