Descriptions:

Rubber core mold also named as different using position, such as concrete core unit pneumatic pipe, prefabricate core unit pneumatic pipe, precast slab pneumatic pipe, and bridge rubber pneumatic pipe and so on.

Pneumatic pipe block is inflatable in soft rubber, use compressibility of air to its elasticity, use rubber to its limpness and gas tightness, and use anti-tensile cloth to its toughness. And then it is make for different shape under particular pressure, and at the same time it could sustain some concrete pressure, and at last, achieve its function of making holes.

 

Features:

1. Content design requirements, operate simply, save of labor, save time and save material.

2. Use natural rubber and nylon cloth, and then vulcanization. Good anti-expanded strength, elasticity, suppleness, resisting high temperature and best separate performance.

3. Apply to wide range temperature.

4. Construction technology is simple and convenient, safe, and health. It would not pollute the environment.

 

Application:

This product is based on the technique of preliminary-making concrete hollow slab inner mold, so it can be used in the project of building bridge, culvert and concrete hollow slab.
