The present invention relates to an embedded barricade using a reaction force of a spring. An objective of the present invention is to provide a high efficiency embedded barricade which has a hydraulic cylinder and a reaction means when a screen of a barricade embedded on a road to control vehicle passage is rotated to protrude or stored to reduce an amount of oil of the hydraulic cylinder operating the screen to reduce a size of a hydraulic motor to reduce energy consumption according to drive and use an extending force or a contracting force provided by a reaction force to quickly rotate the screen to protrude or store the screen. The embedded barricade using a reaction force of a spring comprises: a storage unit (11) embedded in the ground on a road; a screen (13) to rotate and protrude from the storage unit (11) to block entry of a vehicle; a hydraulic cylinder (14) wherein one end thereof is connected to the storage unit (11) and the other end thereof is connected to one point of a lower portion of the screen (13) to rotate the screen by extension or contraction of a piston rod (141); and a spring reaction means (15) installed between one point of a bottom of the storage unit (11) and one point of the lower portion of the screen to provide a reaction force for a weight of the screen when the hydraulic cylinder operates. |
