The drainage channels are of type I (self-supporting drainage channels) in accordance with standard EN1433. The prefabricated U-channels are made of vibrated and reinforced concrete (C 55/67). Due to its design, the drainage channels have a built-in resistance of strength class F, 900 kN. The proposed resistance is guaranteed by the whole. The drainage channels have a tongue and groove connection, and a recess for safety joint (SF). With a liquid-tight version, this recess must be sealed. Galvanized steel posts provide improved connection and straight-line placement. The gutter tops are fitted with an integrated edge protection in galvanized steel, anchored in the concrete. The drain channel complies with European Standard EN1433. Dimensions: length 2.25 m; inner width 420/440 mm (bottom / top); outer width 620/600 mm (bottom / top); inner height 400 mm; external height 480 mm. The drainage channel has a hydraulic section of 1415 cm2 / m. Weight 905kg
Pre-assembled BANANA ductile cast iron grille FGS 500-7, length 75 cm. The grate is supplied bolted on the drainage gutter: 4x bolted with stainless steel bolts (ie 12x bolted / drainage gutter), the stainless steel bolts are anchored in sleeves that are connected to the reinforcement. The slots in the grid are banana-shaped and have a width of 30 mm. The grids are provided with diamond-shaped profiles to increase the water collection capacity and prevent slipping. The grille complies with load class F, 900 kN according to European Standard EN 1433. Absorption area = 2380 cm2 / m.
The self-supporting gutters allow installation without lateral concrete sheathing (only a foundation is necessary). Installation instructions available on request.
