This product is made of natural rubber and anti-Raab hot vulcanization molding, is one of the bridge and tunnel project engineering into the hole mold of the best products, which belongs to a cylindrical, cross-section of a variety of models, rectangular, octagonal and a variety of shapes oval, circular, crown, as well as inverted trapezoidal, etc., can be made according to the construction unit of the corresponding cylinder design drawings. Second, because the steel template background wooden template in use more or less there are some flaws, such as: concrete pouring will release a lot of heat, resulting in extremely hot steel template odd to be in a good place of ventilation in casting, Gaps exist and templates appear tainted plasma phenomena, there are some small aperture slab, into the person simply can not operate, these have caused some difficulties to form removal. Wooden model of the production process is quite complex, waste wood; and more difficult fixed and stripping, turnover number is relatively low. These power products are created to replace the rubber mandrel bridge, bridge rubber mandrel for the convenience of an operation, using simple hollow concrete into the hole mold release agent before using smear enough, let go after the use of gas as long as, The mold can be withdrawn. It uses hot vulcanized rubber and anti-Raab molding process, not only smooth surface without seams, and can take the heat and pressure sufficient concrete. Third, the use of hollow steel slab and side molding (to ensure flatness, can use fixed steel template, end mold can use a large area of ??bamboo production size and requirements After the check, before pouring concrete, concrete casting, vibration, and other ingredients to solid precast concrete substantially the same) precast reinforced concrete hollow core slab using inflatable rubber craft as follows: steel, templates and other tests - pouring concrete at the bottom of the mandrel - installation mandrel (pressure control ) fixed, inflatable - pouring concrete on both sides (from both sides simultaneously vibrated) - cast upper concrete - conservation - form removal - Conservation
