GASKETS FOR SEGMENTAL TUNNEL LINERS

This article describes elastomeric compression gaskets for bored tunnels, and specifically for the Channel Tunnel. The author believes that these gaskets, when properly designed and manufactured, can fulfil all sealing requirements for today's tunnels, whatever the method of tunnel construction. Although the size and configuration of the gasket can vary, all gaskets must fulfil the following performance criteria: (1) relative ease of installation; (2) ability to accommodate construction tolerances and differential movement between components; (3) ability to provide an efficient, watertight seal during the planned service life of the tunnel. To achieve a sealing system which will fulfil the performance criteria for a given tunnel project, a series of specific laboratory tests must be performed, to evaluate the gasket and its mounting surface or groove. The article outlines these tests, and describes briefly the design, manufacture and installation of the gaskets. It then considers the use of elastomeric compression gaskets in: (1) the New Elbe Tunnel; (2) the Antwerp Metro; (3) the Sheffield Interceptor; (4) the Ahmed Hamdi Tunnel under the Suez canal; (5) the Channel Tunnel. Finally, it discusses the quality control of gaskets.
