The installation technology of the grillage to the tips of the BAU screw piles is simple and reliable. Ogolov-inserts of flange and U-shaped type are inserted into the screw foundation of the T series, fixed with four bolts, and immediately a wooden beam is attached to them — the grillage with the help of self-tapping screws. Wooden bearing beams are fastened to the flange of a pile of the F series with the help of grouse screws, metal support structures are fixed with the help of bolted or welded joints, and solid reinforced concrete through knitting reinforcement with flanges.
