Abstract

FIELD: engineering obstacles, applicable in arrangement of obstacles in tank-approachable directions in the conditions of areas of eternal congelation and in the course of defensive operations. SUBSTANCE: an artificially made ditch in the conditions of eternal congelation forms an ice crosspiece preventing the normal movement of underground water. As a result, water, resting on the crosspiece, rushes upwards, breaks up the surface layer of the ground and forms an iced barrage. For uniform spreading of the iced barrage over the entire width of the tank-approachable direction use is made of movable antiicing obstacles. EFFECT: produced continuous zone of iced barrage impassable for the ground equipment and armament of all kinds in the tank-approachable direction in the conditions of limited time of defense preparation and absence of sufficient personnel. 2 dwg

Description

 The invention relates to engineering barriers and can be used to arrange barriers in tank accessible directions in areas with a cold climate during preparation and during defensive operations.

 Closest to the proposed is a method of combating ice on roads and road structures in the Far North [1, 2].

 This method is based on natural processes characteristic of permafrost regions. Underground groundwater flow in these conditions can be intercepted and artificially created ice in the right place. For this purpose, a moat (ditch) breaks off or a strip of land is simply exposed, moss, snow, shrubs are removed in order to accelerate the freezing of soil in this place. A frozen jumper (permafrost belt) appears under the moat or peeled strip, connecting with permafrost and blocking the path to groundwater. Water comes to the surface and forms ice in the right place.

 The disadvantage of this method is the impossibility of creating a solid line of barriers along the entire front, since due to the lack of a continuous flow of groundwater, separately generated ice can not serve as a sufficient obstacle to delay the enemy.

 The technical result of the invention is to increase the reliability of the fence and ensure its obstruction, and due to the formation of a continuous strip of uniform height along the icy shaft along the anti-tank ditch.

 The formation of an icy shaft with a height of up to 2 meters or more ensures its obstruction for all types of modern armored vehicles.

 The proposed method solves the problem of ensuring a uniform exit of groundwater to the surface and the formation of an icy shaft of the required length. To implement this method, the anti-tank ditch is torn off, while the level of freezing will decrease and reach permafrost or some other waterproof layer. As a result, an impenetrable ice bridge is formed, which blocks the path of groundwater moving along a layer of thawed soil between the water-resistant layer and the lower boundary of the active layer frozen in winter. Incoming groundwater will accumulate at the ice jumper and look for a way out. Under its pressure, the earth will swell, forming a hillock, inside of which there will be ice and water. The water pressure will increase, and the hill will give a crack through which the water will break out, flow and freeze, turning into ice. Ice will close the further exit to water, which will continue to accumulate. Again, the pressure will increase, the tubercle will grow, give a crack, and water will come to the earth's surface. This repeating process will lead to a scab of large icy ramparts (bumps), which, together with the anti-tank moat, will create a combined, artificial insurmountable obstacle for advancing enemy armored vehicles in separate directions both from the rear and from the front.

 To ensure uniform freezing and distribution of groundwater emerging on the surface along the front of the proposed fence, anti-icing obstacles are installed.

 Anti-slip obstacles are set in such a way as to ensure uniformity of freezing and distribution of groundwater emerging on the surface and the formation, thereby of almost the same height of the icy shaft along its entire length, which ensures its reliability and impassability. To do this, anti-slip obstacles are mobile. In places where large amounts of water come to the surface, anti-icing obstacles move away from the icy shaft, and where water comes out in small quantities, they move to the icy shaft. The preferred option is to ensure uniformity of the height of the icy shaft both in height and in width. The main indicator is, nevertheless, the uniformity of the height of the icy shaft, which gives the enemy the impression of the absence of weak spots in the fence and forces him to spend time searching for such weak spots to overcome them. If the height of the icy shaft is uneven, then the enemy will first of all try to overcome it in those places where the height is the smallest.

 The invention is illustrated by drawings, where figure 1 shows a method of device anti-tank barriers, and figure 2 presents a diagram of the location of the barriers on the ground.

 At the same time, this method can significantly reduce the time and reduce the complexity of the advance creation of a system of engineering barriers in the tank-accessible direction when equipping the border territory during the threatened period in the Far North.

Claims (1)

 A method of arranging a fence in which an anti-tank ditch is torn across the entire width of the tank-accessible direction, characterized in that the anti-tank ditch is torn in areas with permafrost and form an ice wall in winter conditions up to 2 meters or more in height along the said ditch due to swelling of the soil and exit to the surface of groundwater, while along the icy shaft with the possibility of movement establish anti-icing obstacles, through which ensure uniform distribution and freezing leaving them on the surface of the groundwater along the front fence.
