Rubber Material Inflatable Bladder Inflatable Culvert Balloon

The inflatable rubber core mold is a cylindrical bag that can be expanded and contracted to form the cavity of the concrete member. When the hollow member is made, it is put into the middle and filled with compressed air. When the concrete is solidified, the compressed air in the bag is released and the capsule is shrunk, and the capsule can be extracted from the cavity. It is easy to use, economic and durable, uninflated soft shrinkage, arbitrary folding, curling, inflatable expansion has enough strength to withstand the pressure of concrete, which is unmatched by any traditional rigid formwork. It is suitable for pumping holes of reinforced concrete components, including piles, roof frames, roof plate columns, beams, tunnels and other components, which are widely used in industrial and mining foundations, highway Bridges, construction projects, water conservancy projects (dock, berth, wharf). The construction practice has proved that the capsule extraction process equipment is simple, not only saving materials, and has the characteristics of changeable shape, such as round, oval, rectangle, arch, octagon, trapezoid pipe. Can also become straight hole, change the face, can make the building structure light, thin wall hollow, change the concrete has been using the rigid template.
