CTS-Anchored-SH (Geometry and dimensions) Groove design: Profile:
CTS-Anchored-SHCTS-Anchored-SH combines the technological features of CTS-SH and CTS-Anchored Seal in a perfect symbiosis The advantagesRefer to CTS-SH und CTS-Anchored-SH SealAll CTS-Anchored-SH seals are supplied as ready corner-vulcanized and project specifically tailor-made gasket frames. The profile geometry and also the procedures used for the project-related water-proofing performance and load-deflection behavior testing follow the recommendations of recognized institutions such as, e.g.:STUVA (GER), AFTES (F), and BTS (UK). The gasket installation The CTS-Anchored-SH seal is directly clipped into a specially designed gasket groove machined in the inner face of the tunnel segment casting mold.The installation of the hydrophilic cord CTS-Teco-Swellis performed shortly before bringing the segments into the tunnel by using a special tool provided by CTS. The tunnel segment installationTo obtain a proper seal, care must be taken to insure the gaskets are not damaged during installation. For the insertion of the key stone segment CTS recom-mends using the CTS-Teco-Lube on the gasket frames.The materialThe CTS-Anchored-SH Seal is made of a high quality EPDM compound and its physical properties are in line with the specified values found in the STUVA recom-mendations. In case of special requirements concerning chemical resis-tance when used in extremely contaminated ground CTS offers alternative materials ( e.g. CR/SBR elastomer for better resistance against hydrocarbons found in ground water ). This alternative material can be offered as a rea-sonable compromise, but always under consideration of lowering the typical and physical properties of an EPDM-compound with regard to aging performance and longivety. The hydrophilic round cord CTS-Teco-Swell is made of a swellable TPE material with good permanently elastic properties.
