Brine distribution chambers must be liquid-tight and preferably made of PE material. Suitable shut-off devices must be provided in the flow and return to each circuit or probe. Appropriate control devices must be installed on the distributors for the hydraulic balancing of the probes. Filling and ventilation fittings must be provided.
Static requirements must be considered during chamber installation and backfilling. Special requirements such as traffic loads or installation in standing water must be taken into account in the structural chamber design and must be inquired about separately. Depending on the load case, additional on-site measures for load distribution or buoyancy control may be required.
The chamber must be backfilled in layers with non-cohesive filling material that complies with the relevant standards and must be compacted in layers. The filling material must be easily compactable, permeable, shear-resistant, frost-proof, and free from sharp objects. The specifications for bedding according to DVGW W 400-2 and ATV-A 127 worksheets as well as DIN EN 805 must be observed. Building over and/or influences from foundation loads of buildings or similar must be excluded. The corresponding distances from buildings or other structures must be maintained.
The manufacturer’s installation instructions must be observed.
