AN OF OVRHEAD DROPS TYPE REJECTION FACLITY FOR ARMY TO ROAD TUNNEL AND WALL

摘要

The present invention relates to a military high-rockfall shielding facility used on roads or tunnels. The facility is used to drop shielding walls to block a travel path when a road, tunnel, or bridge needs to be closed in case of a military emergency to effectively prevent enemy vehicles and tanks from moving. The facility includes: a shielding wall support structure rigidly installed on the entrance of the road or tunnel; and shielding walls which are dropped along the guide grooves of the shielding wall support structure to shield the road or tunnel. The shielding wall support structure includes a shielding wall support threshold formed on the upper end of a facing guide groove; and a stopper which is arranged on the shielding wall support threshold of the shielding wall support structure while protruding from side surface of the shielding wall to the outside to support the loead of the shielding wall. The stopper of the shielding wall is blasted to drop the shielding walls along the guide groove of the shielding wall support structure.
