Products Description
XUYUAN inflatable mandrel is also called the bridge inflatable mandrel. The rubber inflatable mandrel is a cylindrical bag that can be expanded and contracted. It is made of vulcanized rubber and fiber reinforced layers. It has high tensile strength, elasticity and air tightness. It is used to form the cavity of the concrete component. When the hollow component is manufactured, it is placed in the middle and filled with compressed air. After inflation and expansion, it has enough strength to withstand the pressure of the concrete and can replace the original wooden mold and bamboo mold and steel mold, the capsule will shrink when the valve is opened, and the capsule can be withdrawn from the cavity.

Classification
Classification
1. Divided by shape: round rubber bridge inflatable mandrel, octagonal bridge inflatable mandrel, elliptical bridge inflatable mandrel and rectangular bridge inflatable mandrel.
2. Divided by use: bridge inflatable mandrel and tunnel inflatable mandrel.
3. According to whether the diameter is reduced or not: inflatable mandrels for reduced-diameter bridges and inflatable mandrels for constant-diameter bridges.
4. According to other classification methods: rubber inflatable core molds, inflatable rubber core molds,prefabricated bridge slab inner molds, box girder inner molds, bridge inner molds, hollow slab inner molds, hollow slab core molds, etc.

Application:
It is mainly used in the pouring and forming project of the pre-tensioned and post-tensioned beams of highway bridge concrete. It is also adopted by the culvert sewage project. The rubber airbag is a kind of expandable and shrinkable inner mold of different shapes made by vulcanizing the polymer properties of rubber and high-strength fiber cloth. After being filled with compressed air, the airbag stretches and expands to meet the design requirements of its cross-section. The inflation pressure and cross section shape can be customized by buyers. It can also be withdrawn from the cavity. It is easy to use, economical and durable, and can be reused many times. It is soft and can be shrinked folded and curled when not inflated. After inflation and expansion, it has enough strength to withstand the pressure of concrete. It is suitable for pumping holes in reinforced concrete components, including piles, roof truss, roof slab pillars, beams, construction projects, water conservancy projects (dock, slipway, wharf) and so on.
