FIELD: building, particularly erection of all-purpose underground structures having deep foundation pit of irregular shape. ^ SUBSTANCE: method involves building enclosing walls, two-stage foundation pit excavation, wherein the first stage includes anchoring of enclosing walls with cross-pieces; and assembling frame. Additionally installed within contour defined by enclosing walls is sheet-pile enclosure. Cross-pieces are arranged between enclosing walls and sheet-pile enclosure. The first stage of foundation pit excavation is performed in thrust support between enclosing walls and sheet-pile enclosure and then contour frame members are mounted in developed pit area. The second stage of foundation pit excavation includes developing inner pit part after which frame erection is completed. ^ EFFECT: improved structure stability, reduced labor inputs, material consumption and increased reliability. ^ 4 cl, 2 dwg |
