CONSECUTIVE HIGH-SPEED LIFTING TYPE UNDERGROUND BARRICADE
The present invention relates to a continuously and rapidly rising buried barricade. The purpose of the present invention is to provide a buried barricade wherein oil supplied from an oil supply part together with oil pre-stored in an additional oil supply part is supplied to a hydraulic cylinder so that the barrier of the barricade can rise rapidly in the case of an unapproved vehicle approaching, and the additional oil supply part always maintains a full state and supplies oil additionally when necessary so that the barrier can rise rapidly. The buried barricade according to the present invention comprises: a receiving part buried underground below a road; a barrier for blocking the entry of a vehicle by rotating and rising from the receiving part; and a hydraulic cylinder for rotating and raising or lowering the barrier with respect to a hinge axis by being expanded or contracted by oil supplied from the hydraulic pump of the oil supply part. The continuously and rapidly rising buried barricade further comprises: an additional oil supply part including an additional oil line intercommunicating with one position of an oil supply line leading from the oil supply part to the hydraulic cylinder to raise the barrier rapidly by supplying additional oil to the hydraulic cylinder during the rise of the barrier, and receiving oil, which used to be supplied from the oil supply part toward the hydraulic cylinder, through the additional oil line during the fall of the barrier.
