Rubber Inflated Culvert Balloon for Hollow Slabs
    The rubber inflated culvert balloon, also known as the bridge inflatable core mold, is an expandable and contractible cylindrical bag made of rubber with a fiber-reinforced layer, featuring excellent tensile strength, elasticity, and air-tightness. It is primarily used to form cavities in concrete components.
    When manufacturing hollow components, the inflatable core mold is placed in the middle of the component and is expanded by injecting compressed air. The inflated core mold can withstand the pressure of concrete, thus effectively replacing traditional wooden, bamboo, and steel molds. When in use, simply open the valve, and the airbag will deflate, making it easy to remove from the cavity.

Features
*High Pressure Resistance: Working pressure 0.04-0.06MPa, burst pressure ≥0.15MPa

*Excellent Air Tightness: Pressure drop <3kPa in 24-hour test

*Optimal Flexibility: Easy to fold and store with good rebound

*Puncture Resistance: Surface puncture strength ≥80N

*Temperature Adaptation: Normal use in -20℃ to +60℃ environments
Product Features
Culvert Concrete Making Rubber Airbag Inflatable Rubber Airbag for Bridge
*Flexible and Easy to Use: Soft when deflated, can be folded and rolled, making handling and placement very easy.

*High Strength and Stability: Thanks to the composite structure of rubber and high-strength fiber skeleton, the airbag maintains a stable shape after inflation and has strong load-bearing capacity.

*Excellent Durability: Features abrasion resistance, aging resistance, acid and alkali resistance, ensuring a long service life.
*Economical and Efficient: Compared to traditional rigid templates, it offers lower cost per use and significantly shortens the construction cycle-7.
Applications
Inflatable rubber culvert airbags are widely used in civil engineering and construction for manufacturing various reinforced concrete hollow components:
    *Highway and Bridge Engineering: For precast or cast-in-place circular culverts, box culverts, arched culverts, etc., and some hollow components in bridges.
    *Municipal Sewage and Drainage Engineering: For manufacturing large drainage pipes, sewage pipes.
    *Water Conservancy Engineering: Applied in the formation of hollow concrete components in facilities like dry docks, shipways, docks.
    *Building Foundation Engineering: Suitable for concrete components requiring cavities, such as piles, roof trusses, roof slabs, columns, beams.

Requirements for the rubber inflated culvert balloon for hollow core precast beams:
*When installing the rubber inflated culvert balloon, the length specifications of the hollow core precast beams are usually 8 m, 10 m, 13 m, 16 m, 20 m, 25 m, and 30 m; lengths exceeding 30 m are generally not designed as hollow core beams.

*For culvert balloons below 13 m in length, the inner culvert balloon is generally made of rubber; for culvert balloons above 16 m in length, there is more flexibility in the choice of inner culvert balloons, which can be rubber, wood, or steel.

*During the construction process, the rubber inflated culvert balloon is placed inside the rebar cage, inflated with compressed air to form the desired cavity shape, and withstands the pressure during concrete pouring. After use, it can be deflated and removed from the cavity, allowing for multiple reuse.
