Shield tunnelling method has been widely applied to construction of underground structures in urban area and a demand for long distance tunnelling under high underground water pressure isgrowing recently.<BR>To deal with the demand, we have been developed a high durability new tail-end-sealing system which is made by filling up ordinary wire brush with poly urethane form. However, for more long distance tunnelling, it is necessary to have aditional technology which make able to replace damaged tail end seals with new one.<BR>We designed a new sealing system which is applied technique of preceding new tail-end-sealing system. A series of fundamental efficiency tests has been carried out.<BR>As a result, it was clarified that the new sealing system has higher sealing performance and higher durability.
