GROUND STRUCTURE ON WEAK BASE

摘要

FIELD: construction.SUBSTANCE: ground structure on a weak base comprises an embankment, trenches made at its both sides and a reinforcing system in the form of a horseshoe-shaped retaining shell with a vault and supports. The retaining shell is arranged in transverse and longitudinal direction of the ground structure from webs of a synthetic non-woven material (SNM) laid into the embankment and trenches. Webs of the SNM in trenches are filled with soil, forming supports of the horseshoe-shaped retaining shell. The retaining shell is made in the form of a closed shell, its vault is installed in the embankment body and is filled with soil. The volume weight of soil in the horseshoe-shaped retaining shell exceeds the volume weight of embankment soils.EFFECT: provision of a reliable and durable earth structure on a weak base in process of permanent operation without drying of weak soils in area of any length.1 dwg
