N. Nikonov. Artificial constructions of railway transport. - M.: State. transp. VC. ed., 1954, S. 362, Fig. 465).

The lack of gravity gabion walls, as well as all of gravitational structures is relatively small holding capacity and a large amount of stone material.

The objective of the invention is to improve the stability and retention, as well as reducing the material intensity of a retaining wall located on top of each other graded, filled with stone material gabions installed on the pile caps.

The problem is solved due to the fact that the retaining wall comprising spaced on each other graded, filled with stone material gabions installed on the pile caps, according to the invention in the grillage with the ledge, fixed metal or reinforced concrete trusses, between which there is associated the gabion.

The technical result provided provided soeylemez retaining walls located on top of each other step, filled with stone material gabions installed on the pile caps.

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.
