Pipe installation must be carried out by qualified workers under professional supervision.
When installing the pipes, it is necessary to follow the general guidelines for laying pipes that are laid in the ground and are roughly defined in the standard SIST EN 1610 and also in the standard DIN 4033.
With proper preparation of the bed (thickness 15 cm) with sand or other soil that can be hardened and which does not contain stones (grains up to 20 mm), good and gradual hardening of the backfill (degree of compaction according to Proctor Dpr> = 95%) at pipes and 30 cm above the top of the pipes, it is achieved that pipes covered with earth from 0.8 m and up to 8 m and even under the heaviest traffic load SLW 60 (according to DIN 1072) are not deformed above the permissible limit 6 %. If the pipe cover is less than 0.8 m, it is necessary to take care of load distribution (eg by concreting).
More detailed installation instructions can be found in the “DOWNLOADS” category, where, in addition to the catalogs, you will find guidelines for laying pipelines, which deal with ditch excavation, bed construction, overlapping and main backfilling of the pipeline. General guidelines for testing the tightness of laid pipelines in accordance with SIST EN 1610 are also available.
