METHOD FOR DETERMINING LOAD-BEARING CAPACITY OF GROUND AT DRIVING PILES Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: according to method, at driving piles to required depth with subsequent final driving, used for determining load-bearing capacity of ground is measuring device connected with pile. Pile for this purpose is made up of two half-piles interconnected by link during driving. Pile is equipped with pressure sensors secured on one of half-piles at level of pile point and covered by side of other half-pile. After major driving cycle, connecting link is removed and pile is finally driven by 5-10 blows which caused cleaving of pile by ground core and transmission of pressure to sensors connected with graduated device. EFFECT: high efficiency. 2 dwg
