The utility model of the road protection structure for highway engineering construction, by setting a rectangular frame, can effectively play a protective role when workers are constructing the highway. By slidingly connecting the rectangular frame with the connecting rod, the rectangular frame can be displaced to perform a partial force unloading effect during the process of being hit by external force. By setting an energy-absorbing component, it has a good force unloading effect. By arranging a plurality of anti-collision barrels in the rectangular frame, it can be deformed when it is hit, thereby effectively playing a role of force unloading and protection. Compared with the traditional rigid structure, it has better anti-collision and protection capabilities;

[0003] The above-mentioned patent produces deformation when the crash barrel is hit, which plays a role of unloading and protecting, and mainly cushions the impact through the material of the crash barrel itself. Therefore, the cushioning effect of the crash barrel needs to be improved. Secondly, after the crash barrel is hit, the structure between the rectangular frame and the crash barrel is fixed, so the whole needs to be replaced, and there is an intact crash barrel in it, which causes waste.

[0013] The utility model has the following beneficial effects:

[0014] 1. Through the design of the crash barrel, the principle of rolling guide energy dissipation after impact is used to convert the impact energy perpendicular to the guardrail into rotational energy parallel to the crash barrel, thereby effectively decomposing the impact force of the car. The design of the mounting seat can replace the damaged crash barrel without replacing the entire device.

The upper and lower ends of the anti-collision barrel 4 are composed of a rotatable rotating rod and a barrel body, and the rotating rod realizes the rotation of the barrel body and is fixed to the mounting seat 3. The motion principle of rolling guide energy dissipation after the collision is used to convert the impact energy perpendicular to the direction of the guardrail into rotational energy parallel to the direction of the anti-collision rotating barrel, thereby effectively decomposing the impact force of the car. The upper end of the anti-collision barrel 4 is provided with an inlet 8 for water inlet, and the lower end is provided with an outlet for drainage.

The mounting assembly includes a mounting plate 10 fixedly mounted on the side wall of the column 2. The side wall of the rectangular frame 1 is provided with a mounting groove adapted to the mounting plate 10. Both the mounting plate 10 and the mounting groove are T-shaped structures. The mounting plate 10 is directly inserted into the mounting groove to complete the connection between the column 2 and the rectangular frame 1, which is simple and quick.

[0025] A slide groove 11 is provided on the side wall of the column 2, and a slider 13 is slidably connected to the inner side of the slide groove 11. A locking block 12 is fixedly installed on the upper end of the slider 13, and a locking bolt is threadedly connected to the locking block 12 (not shown in the figure).

[0026] Working principle:

[0027] When in use, loosen the locking bolt, move the slider 13 downward, and then use the cooperation of the connecting plate 14, the diagonal support plate 5, the unfolding plate 6, and the support 7 to put the unfolding plate 6 in a horizontal state and the diagonal support plate 5 in an inclined state to achieve the purpose of unfolding support. Then tighten the locking bolt to fix the unfolding plate 6, and the unfolding plate 6 contacts the ground for support so as to be used for road protection. Otherwise, the unfolding plate 6 can be folded to reduce the occupied space and facilitate transportation.
