CTS-Standard (Geometry and dimensions)
Groove design:
Profile:
CTS-Standard
The CTS-Standard seal is a classic mono-compression seal.
Embedded within a groove around the tunnel segment
and interacting with the opposite seal of the neighbouring
segment it seals the circumferential and radial segment
joints. Restoring and contact pressure forces developing
from both compressed profiles increase with decreasing
joint gaps and produce the grade of water tightness.
The advantages
Under consideration of the specific groove design and
joint configuration details recommended by CTS the latest
generation of CTS-Standard profiles provides improved
sealing capacities with concurrently reduced compression
forces.
The profile provides balanced and stabilized deformation
behavior with an almost equal sealing performance at
different offset scenarios.
All CTS-Standard 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 recom-
mendations of recognized institutions such as, e.g.:
STUVA (GER), AFTES (F), and BTS (UK).
The gasket installation
The CTS-Standard seals are optionally installed either
by “brush-on” or “spray-on” gluing method.
The CTS-Teco-Bond-Gluing-System is recommended.
The tunnel segment installation
To 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 material
The CTS-Standard seals are made of a high quality EPDM
Compound that meets the material requisition recom-
mended by STUVA.
In case of special requirements concerning chemical
resistance 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 reasonable
compromise, but always under consideration of lowering
the typical and physical properties of an EPDM-compound
with regard to aging performance and longevity.
