The initial, intermediate and final sections, based on their guides 3, 4, and 5, rely on the sliding guides 2, respectively, while the 3-5 guides are made in the form of square tubes, the internal dimensions of which are commensurate with the profile of the sliding guides 2. The 3-5 guides are fixed on the guides Sliding with 2 bolted joints 23.

The initial section (see Fig. 2) is made of a pair of identical rectangular frames, each of which is made of a pair of parallel vertical posts 6, supported by the guides of the initial section 3. Between the vertical posts 6 in the upper part and the guides 3 in the lower part of the frames, cross members are mounted 7. The frames are interconnected by longitudinal guides 8 (see Fig. 3), and a pair of opposite corners of each side of the frames are additionally connected by diagonal guides 9. The joints of the vertical posts 6, the cross members 7, the guides 3 and are longitudinal x guides 8 are reinforced with triangular stiffeners 10 mounted at the inner corners of the initial section.

An intermediate horizontal cross member 11 is mounted inside the first frame of the initial section in its central part between the uprights 6, and one intermediate vertical cross member 12 is mounted between the intermediate horizontal cross member 11 and the cross members 7.

Inside the initial section, a guide pipe 13 is mounted to the vertical posts 6 and the cross members 7, while one of the ends of the pipe 13 abuts against the intermediate horizontal 11 and vertical 12 cross-pieces of the first frame of the initial section.

The intermediate sections (see Fig. 4) contain vertical posts 6, supported by the guides of the intermediate sections 4. The vertical posts 6 in the upper part and the guides 4 in the lower part are connected by cross members 7. Inside the intermediate sections in their central parts are on the holders 14 located along to the corners of the frames, guide tubes 13 are mounted in such a way that one end of the pipe 13 rests on the holders 14, the second end of the pipe 13 is inserted into the pipe 13 of the initial section after the first section of the intermediate section, and each subsequent the daily section into the pipe 13 of the previous section, while the outer diameter of the guide pipes 13 decreases from the initial to the last intermediate section with a step equal to the thickness of the pipes. The hole of each part of the pipe 13 inserted into the pipe 13 of the adjacent section is made tightly closed.

The final section (see Fig. 7) contains vertical posts 6, resting on the guides of the final section 5. Vertical posts 6 in the upper part and the guides 5 in the lower part are connected by cross members 7 (see Fig. 7). A vertical intermediate post 15 is mounted centrally between the cross members 7 and horizontal cross members 16 are mounted between the vertical intermediate post 15 and the vertical posts 6. The upper ends of the vertical posts 6 are connected to the rear ends of the guides 5 by the inclined stops 17. In the front part of the end section, it is perpendicular to the vertical intermediate the stand 15 is mounted emphasis, made in the form of a pair of horizontal guides 18 in the front of which is mounted a rectangular thrust frame 19. Connection horiz ntalnyh abutment guides 18 and vertical intermediate pillar 15 is strengthened by triangular stiffeners 10 attached to the horizontal beams 16 at both sides of each of the horizontal rails 18.

The sliding guides 2 in the front part in front of the initial section and in the rear part after the final section are interconnected by traverses 20 (see Fig. 8). The final section of the supports 21 mounted in the lower part is supported by additional supports 22 mounted in the ground base.

To the uprights 6 of the initial section, bolted joints 23 are attached to the side beams 24 (see Fig. 10). To the uprights 6 of the intermediate and final sections, bolted joints 23 are attached to the side beams 25 (see Fig. 11). Side beams 24 and 25 are made of a curved profile with the possibility of increasing the resistance to deformation when a vehicle collides with them.

A damping element 26 is mounted in front of the initial section.

The front guard pipe type is used as follows.

At the moment of a frontal impact during a collision with a fence, the vehicle initially acts on the damping element 26, deformation of which reduces the kinetic energy of the impact of the vehicle. At the same time, the initial section, on which the damping element 26 is fixed, is driven in translational motion along the sliding guides 2 to each subsequent intermediate sections, while the kinetic energy is dissipated by dissecting the bolts of the joints 23 connecting the guides 3, 4 of the initial and intermediate sections with the sliding guides 2 and bolted joints 23 connecting the side beams 24 and 25, the movement of the initial and intermediate sections along the slide rails 2, the movement of the pipes 13 and due to the work on Deer of increasing pressure in the tubes 13 as they move within each other.

The claimed technical result - the reduction of the complexity of restoring the fence is achieved due to the fact that the dissipation of kinetic energy from the vehicle during its frontal collision with the fence is due to the work of the fence elements used to dissect the bolts of the joints 23 connecting the guides 3, 4 of the initial and intermediate sections with sliding guides 2 and bolted joints 23 connecting the side beams 24 and 25, moving the initial and intermediate sections along the sliding guides 2, the movement of the pipes 13 and due to the work to overcome the increasing pressure in the pipes 13 when moving inside each other and to restore the fencing to work, it is only necessary to move the displaced intermediate and initial sections to their original places along the slide guides 2, replace, if necessary, damaged bolted joints 23 and damping element 26.

In 2016, the applicant made a prototype of the front fence, trial operation, which was confirmed by the achievement of the claimed technical result.
