Custom Molded Rubber Parts steel-edge rubber waterstop sheet

applied for duct piece joint of shield segment tunnel, conduit joint, underground engineering, infrastructure deformation joint, construction joint and settlement joint.

1) Material: EPDM+ Steel

2) Molded rubber

3) Steel-edge rubber waterstop sheet is a kind of new rubber waterstop by inserting galvanized steel sheet into the middle of vulcanized rubber, which is applicable to construction field with high pressure and large structure variable.

4) When structural deformation is large, the cross section of common rubber waterstop will be elongated and thin with structure sedimentation, concrete shrinkage and creep. Once deformation is beyond its fatigue limit, new leakage crack will be formed. However, when steel-edge rubber waterstop is used, there is strong adhesive between the plates at both sides and surrounding concrete structure and between steel sheet and rubber. Once structure deformation occurs, rubber part will be elongated and thin, while new leakage crack will not be formed between steel sheet and concrete, between steel sheet and rubber. Therefore, steel-edge rubber waterstop not only enhances barrier performance of structural deformation, but also plays an important quality assurance role in waterproof in the whole project.

Products are applied for duct piece joint of shield segment tunnel, conduit joint, underground engineering, infrastructure deformation joint, construction joint and settlement joint.

Main products include shield segment waterproof rubber seal, hydrophilic expansion rubber seal.

Products are applied in many important projects both in domestic and abroad, such as Beijing subway, Shanghai subway, Guangzhou subway, Korea Drainage Works.

In the process of participating in engineering construction, our company have not only mastered technical capacity of producing shield segment waterproof materials, but also accumulated rich experience on mechanical structure, mechanical conditions and seal mechanism of such products. Our company can design a suitable segment seal gasket through finite element analysis, various stress tests of finished products and water pressure-resistant tests under different conditions in accordance with duct size, force size and watertight indexes provided by the customer
