FIELD: mining.
SUBSTANCE: invention relates to a rib for supporting and reinforcing an excavation, as well as a method for supporting and reinforcing an excavation based on use of one or more supporting ribs according to present invention. Rib for supporting and reinforcing an excavation comprises at least a structural element provided with a tubular body with an inner cavity adapted to be filled with concrete after installation of support rib, and a filling device operably coupled to means of injecting concrete into cavity. Supporting rib comprises a ventilation device for discharge of air during injection of concrete, wherein ventilation device is configured for closing during injection, which causes increased internal pressure of concrete. Method for supporting and reinforcement of excavation, comprising steps of installing a first rib, made according to invention, filling inner cavities of structural elements of first support rib with concrete until at least complete filling thereof. Injection of concrete is continued with closed ventilation device in order to increase internal pressure of concrete.
EFFECT: creation of support with high stability.
