Then, a grillage 2 was erected, equipped with gum 5, supported by means of 4 piles on the heads 1 through the glands.

Claims

Invention Formula

The pile foundation of the building was constructed, including piles and a grillage suspended from them by means of a t grillage, so that, in order to simplify the design and facilitate the installation of the grillage and superstructure 5 structures with the exception of the transfer to the building, the construction efforts from the displacement of the soil under seismic action, niches were formed under the pile cap, pile heads, and each, t ha, was made 2Q L-shaped, anchored by the ends in the walls of the corresponding niche and supported by the pile on the niche in this niche, while the gap between impoverished niche and the upper end of the pile pre-

the upper end of the pile 1 exceeds the maximum maximum impulse displacement amplitude of displacement of the soil ground under seismic action under seismic action.
