Culvert balloons

Culvert Balloon is a kind of cylinder bag that can expand, shrink, used to form concrete component of cavity. It is easy to be used, convenient and durable, is soft and can fold, curly, contraction when it isn't inflate, it have the enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional template, it is used in reinforced concrete members, including stake roof, roof board column, beam, building, water conservancy project(shipyards slipway, dock) . Construction practice proves that culvert balloon is simple, not only save materials. And has a shape characteristics, it could be round, Oval, rectangle, vaulted, trapezoidal pipeline. etc. Also you can make a straight hole, etc. can make a building structure light, thin wall hollow .change the concrete performance have been used rigid characteristic template situation.

Features of culvert balloons:

1. Easy to use and disassemble.The rubber airbag is an inflatable product which can be poured into hollow components of various finished products, according to different construction projects.

2. Good aging resistance.Made of synthetic rubber, natural rubber and fiber reinforcement after vulcanization, culvert balloons not only have good anti-expansion strength, but also elasticity and flexibility. It can be used in construction under various working conditions.

3. Necessary conditions for the lightweight construction.Due to the use of rubber airbags to reduce the weight of the upper structure of the building and bridge, the pile foundation can be shortened, the span can be increased, and the on-site construction is simple.

4. Suitable for a wide range of temperatures.The material of culvert balloons will not change in the range of -10°C to +90°C.

Applications of culvert balloons:

1. Concrete pouring for highway bridge culvert 

2. Sewage discharge projects

3. Tunnel Bridge Side ditch construction.

4. Architectural engineering.

5. Irrigation works.

6. Piles, roof trusses, roof plate columns, beams, etc.
