Abstract

A new water-expansion rubber material of injected type has been developed which can use the impermeability of segment joints. It is practiced in Japan. However, the mechanisms of the impermeability have not been clarified. It is necessary to clarify these mechanisms. As the first step a laboratory impermeability test was conducted by using special permeability test apparatus we have developed. As a result, we have found a mechanism of impermeability by blocking effect. Furthermore the critical impermeability pressure could be expressed by a semi-theoretical equation.
