Divisible seals for SRV-G tc.

Sealing speedpipe bundles under ground with divisible seals.

Adjusted to all SRV-G tc: due to the variable gaskets bundles as well as protective ducts - either empty or occupied with speedpipe / cables - remain clean, dry and operational over decades. 

Gas- and water-tight even up to 0.5 bar, the divisible elements fix speedpipe subduct solutions against temperature-affected length modifications.
