Truck load capacity and DIBt® approval
The DRAINMAX tunnel trench was the first in Germany to receive building authority approval from the German Institute for Building Technology. The long-term load-bearing capacity of the DRAINMAX system has been proven for an operating period of at least 50 years. This benefits planners, builders, processors and dealers alike.
To achieve this, in addition to numerous installation tests in practice, elaborate quality and load tests were carried out at the Gesellschaft für Materialforschung und Prüfungsanstalt für das Bauwesen. In addition to material quality and short-term strength, these tests also examine and monitor the long-term strength of the component. The DIBt approval for the DRAINMAX tunnel infiltration trench 60 means maximum safety and proof of quality for dealers, planners, construction companies and operators.
Traffic load according to installation situation
DM-T/12 max. Achslast | DM-T/12 max. Überdeckung P | DM-T/60 max. Achslast | DM-T/60 max. Überdeckung P | |
accessible, unpaved surface | -- | 0,501 - 2,25 m | -- | 0,501 - 3,00 m |
Truck 12t [quivalent surface load = 6,7 kN/m²] unpaved surface | 8,0 t | 0,801,2 - 1,50 m | 8,0 t | 0,501,2 - 2,75 m |
SLW 30 [equivalent surface load = 16.7 kN/m²] paved surface | -- | -- | 13,0 t | 1,00- 2,00 m |
SLW 60 [equivalent surface load = 33.4 kN/m²] paved area | -- | -- | 20,0 t | 1,00- 1,65 m |
1 only valid if the installation area is designated as frost-proof
2 in the case of unpaved surfaces, rutting must be taken into account. the monimal total coverage must not be fallen short of!
