Relaxation device is formed of reinforced concrete slabs arranged in two longitudinal rows and secured to face slab by springs with variable spring force so that reinforced concrete slabs extend at different angles to horizon line. Low row slabs have lesser angle of inclination. Face slab and low slab row are provided with through slots. Foundation plate has cylindrical base and connected to inclined anchor by means of damping device.
EFFECT: reduced building time and operational costs for accumulating cavity cleaning, reduced labor inputs.
FIELD: building, particularly for bordering or stiffening the sides of foundation pits.
SUBSTANCE: method involves driving vertical piles in ground along pit perimeter for depth exceeding pit bottom level; excavating ground up to reaching pit bottom level to open bordering member surfaces facing inwards; securing horizontal distribution beams to above surfaces to create framing belt; installing spaced cross-pieces along pit perimeter; leaning the first cross-piece ends against distribution beams and securing the second ends thereof into pit bottom ground; removing cross-pieces after reinforced concrete pit bottom forming. Ground is excavated to form inner initial pit and then stepped trench is dug out under the protection of thixotropic mix along the initial pit perimeter in direction transversal to bordering formed by piles. Lower trench step is located below pit bottom level and the second cross-piece ends are secured to above step which is then concreted under the protection of thixotropic mix. After hardening support shoe of cross-pieces trench is filled with previously excavated ground and ground is excavated of the pit up to reacting pit bottom level.
EFFECT: possibility to consolidate pit just after the initial pit and framing belt forming.
