REINFORCED SAND BED WITH CURVED BOTTOM

摘要

FIELD: construction.SUBSTANCE: invention relates to construction, and namely to foundation construction and can be used at erection of low-rise buildings and structures on weak clay beds. A reinforced sand bed with the curved bottom for foundations on weak clay beds includes arrangement of the sand bed in the bottom soil. The sand bed bottom has a curved outline for uniform distribution of stresses on a weak bottom, as well as arrangement along the bed outline of geosynthetic material operating for strain and constraining transverse deformations of sand soil.EFFECT: reduction of deformity of a sand bed; reduction of stresses transferred to a weak sand bottom; increase of load-carrying capacity of a weak clay bed.1 dwg
