Product Description
Entrance Rubber, as a seal device used at the entrance for tunnel boring machine, is made of natural rubber or chloroprene rubber, and reinforced with textile which makes it not easy to break. Due to the high elasticity of the rubber material, Entrance Rubber deforms under loads, so as to prevent water leakage and seepage, and play an effective role in shock absorption and cushioning.

Shield opening curtain fabric rubber plate, also known as shield door curtain fabric plate, shield curtain fabric rubber plate, curtain fabric sealing ring, curtain fabric rubber plate, curtain fabric gasket, rubber curtain fabric plate, etc., is used for shield tunneling machine into the mouth of the sealing device, made of natural rubber or neoprene rubber, built-in reinforced curtain fabric, to ensure that it is not easy to break. Using the high elastic characteristics of rubber, the cord rubber plate can be deformed under various loads, so as to prevent water leakage and seepage of the building structure, and play an effective role of sealing and shock absorption.
