MONOLITHIC REINFORCED CONCRETE SUPPORT OF VERTICAL ROUND SHAFT Russian patent published in 2022 - IPC E21D5/00 

FIELD: mining.

SUBSTANCE: invention relates to mining, namely to construction of round shaft under conditions of high mining pressure. Monolithic reinforced concrete support of round shaft includes a concrete body, vertical longitudinal rod working, horizontal rod working steel reinforcement and reinforcing cross brackets with pitch corresponding to design pitch of reinforcement, in form of frame. Vertical longitudinal rod working, horizontal rod working steel reinforcement and crosswise reinforcement brackets of round shaft support frame is made with ellipsoidal cross-section. Long axis of reinforcement ellipse is combined with maximum loads on reinforced concrete round shaft support. For vertical and horizontal fittings maximum moment of resistance along the long axis of the ellipse is combined with round barrel radius direction. For reinforcing transverse brackets maximum moment of resistance along long axis of ellipse is set parallel to vertical axis of round shaft.

EFFECT: increase reliability of monolithic reinforced concrete support round shaft.
