Anchoring of ideas
ANCHORING OF IDEAS
In order for a sludge separator or closed tank, or similar, not to be pushed up at high groundwater levels, well-planned placement and possibly anchoring is required.
In all design work, groundwater should be avoided to prevent problems with tank pressurization. The excavation pit may need to be drained to avoid the tank being pushed up.
A tank to be placed underground should, as far as possible, be placed under well-supported backfill (normally a maximum of 1 m). If these measures are not sufficient to hold the tank in place, the tank should be anchored using straps or geotextile.
The groundwater level must never exceed the bottom of the lowest tank penetration, which is usually the outlet pipe.
Anchoring with only backfill above the tank with at least 65 cm (normally maximum 1 m) of mass with an average density of 1700 kg/m² is a rule of thumb.
Then sometimes many tanks remain if the groundwater does not rise too much and the tank is empty.
If the tank is laid down during the winter, there is a risk that the density of the backfill masses drops and more backfill above the tank is required or anchoring.
Anchoring with straps
Anchoring with straps requires corrosion-resistant straps attached to either rock or concrete slabs or piles. To obtain adequate anchoring over time, the straps should be oversized against the anchoring force required, as textile breaks down in the ground.
Note that the tank can withstand point loads such as straps or wires etc. in the installation manual.
Anchoring with geotextile
A simple way to anchor the tank is to lay geotextile over the tank and then backfill.
Important to keep in mind when using this method is that the geotextile must have a certain tensile strength of at least 7 kN/m² or special anchoring cloths if backfilling is done with at least 30 cm above the tank,
Otherwise, stronger geotextile or double cloths are required and that it must not be damaged by sharp stones and the like.
