Abstract: The invention consists of initial part (2B), which at the lower side is made in pyramid form and is part of mine activating mechanism (1). At its screwing into mine body (3), ampoule (D2) containing the aggressive matter is broken by the sharp point, the matter spills and comes to initial part (2B) that gets immersed in it. The aggressive matter slowly corrodes the walls of initial part (2B) and, when it corrodes them through, it mixes with the initial explosive placed inside initial part (2B), soaks it and neutralizes it, in such a way the initial explosive looses its explosive properties, and the mine cannot be activated any more. Cylindrical housing (D) serves for placing ampoule (D2) and retaining the aggressive liquid after breaking ampoule (D2).

Abstract: The assembly of the mobile swing-gate is installed in the channel that is dug across the entire width of the road, and the sides of the excavation are reinforced by wall (5). The created recess is over-bridged by swing-gate (1). One side of swing-gate (1) is connected onto joint (2) that is fixed onto channel wall (5). The opposite side of swing-gate (1) is supported by support grate (3) that by its upper side leans against swing-gate (1) and by its lower side against the corner of wall (5). Steel rope (4) is attached at the upper side of the support grate. By pulling steel rope (4) the support grate (3) eludes bellow swing-gate (1) that remains without support at that side, rotates about joint (2) and falls into the channel, and in such a way a recess is opened in the road.
