Cover condition for backfilling:
A1
Backfilling compacted in layers against the native soil (without proof of compaction degree);
also applies to plank walls, Berlin lining
A2
Vertical pipe trench lining with boards that are not removed before backfilling.
Lining boards or devices that are removed step by step during backfilling. Non-compacted
backfilling/ backfilling with slurry (only suitable for soils of group G1).
A3
Vertical trench lining with sheet piling, light weight sheet connection, wooden planks, lining
boards or devices that are not removed before backfilling.
A4
Backfilling compacted in layers against the native soil with proof of the required compaction
degree to ZTVE-StB ; also applies to plank walls (Berlin lining). Cover condition A4 is not
applicable to sails of group G4.
Bedding condition for pipe:
B1
Bedding compacted in layers against the native soil or in the embankment (without proof of
compaction degree); also applies to plank walls, Berlin lining
B2
Vertical lining in the pipe zone with planks that reach down to the trench bottom and are not
removed before backfilling and compaction. Lining boards or devices provided that the soil
is compacted after the linings are removed.
B3
Vertical lining in the pipe zone with sheet piling or lightweight sheeting and compaction against
the lining reaching down below the trench bottom. There is no safe calculation model for
determining vertical lining with wooden planks, boards or devices that are not removed before
backfilling and compaction the pipe zone.
B4
Bedding compacted in layers against the native soil or in the embankment with proof of the
required compaction degree to ZTVE-StB. Bedding condition B4 does not apply to soils of
group G4.
