FIELD: mining and construction, particularly dredgers or soil-shifting machines for digging trenches or ditches with digging wheels turning round an axis.
SUBSTANCE: ground excavation method involves lowering soil-shifting tool suspended to at lest one load-bearing cable from load-bearing structure in ground and removing soil-shifting tool from ground by means of load-bearing structure. Load-bearing structure has retentive frame. Load-bearing cable is connected to the retentive frame. During soil-shifting tool lowering and/or lifting from ground part of traction force exerted by load-bearing cable is transmitted to ground by means of retentive frame.
EFFECT: increased simplicity and decreased costs of load-bearing device structure production.
