Product information

Speed
Chassis – a foundation frame with ready-made reinforcement. The
tank is delivered to the construction site on a steel foundation
frame, the entire structure is tied together with bands in the CGH
plant.

Technical details

The frame for ‘SPEED CHASSIS’ comprises I-beam sections welded in the shape of the letter ‘K’. The frame with the tank is put in an excavation and levelled. After arranging possible additional reinforcement, the frame is embedded in concrete to form a foundation block. For setting the tank, a foundation block with a constant thickness of 300 mm and horizontal dimensions equalling the tank diameter x tank length has been provided.

Remarks and recommendations for excavation works

Soil survey has to be carried out when developing a building project for a given location.
When backfilling the foundations, soil from the excavation should be used and laid in layers with a thickness of approx. 0.3 m, while ensuring thorough compaction.
Assumptions for calculations

There is a load-bearing soil beneath the foundation.
The tank will be poured with non-cohesive soil, placed and thickened with layers, γ =18 kN/m3.
The concrete density in the foundation slab of γ =22 kN/m3 was taken for the calculation of tank buoyancy.
Tank weights as per technical sheets of CGH Polska were taken for the calculations.
Tank clamping depth – 0.8 m (backfill layer above the tank).
The XC2 exposure class of the foundation slab was assumed, C16/20 (B20) concrete was taken for this expansion category. If there is water in the ground more aggressive for concrete than for the XC2 category, the composition and brand of a concrete mix has to be modified accordingly.

Notes for concrete works

Due to shrinkage stresses in concrete, proper care of concrete on the construction site is very important. The concrete care method should be determined before any concrete works.
A concrete mix should be applied and thickened in such a way to avoid its segregation. Thickening should be carried out continuously when laying is part of concrete.
