[0003] In the process of building a highway, the construction refers to the construction of the road. In order to ensure safety during the construction process, guardrails need to be used. The Chinese patent with the announcement number CN218092397U discloses a guardrail for highway construction, including a base, two vertical supports and a horizontal rail. The base is a tumbler seat. The guardrail for highway construction is provided with a base, which is a tumbler seat. This structure is similar to the structure of the bottom of some existing tumblers. Its center of gravity is located at the bottom of the base, so that the device can be placed on the ground at will to protect the construction area. However, the length of the guardrail in the above patent is relatively fixed. Since the width of different highways is different during construction, it is not convenient to adjust the width of the guardrail according to the width of the construction highway. The scope of application is low and it does not have a good protective effect. Therefore, those skilled in the art provide a guardrail for highway construction to solve the problems raised in the above background technology. Utility Model Content

The outer surface of the square slide 22 is fixedly connected with two protective L-shaped connecting plates 23. The right end of each protective L-shaped connecting plate 23 is fixedly connected to the outer surface of the column 11, which can pull the right branch box 2 and the square connecting plate 18 to move, thereby sliding the sliding plate 15 on the smooth column 14. At the same time, the column 11 can also be used to slide the protective L-shaped connecting plate 23 and the square slide 22 on the long cylinder 21, so that the relative positions of the left branch box 1 and the right branch box 2 can be adjusted, thereby achieving the position of the right branch box 2 according to the width of the construction road, so that the guardrail 10 can achieve better protection effect, and realize the design of the guardrail as adjustable, thereby improving the scope of application during construction and facilitating the protection of roads of different widths.

[0023] The front of the left branch box 1 is provided with a strip opening 6 that is adapted to the size of the round long rod 16, and the outer surface of the left branch box 1 is provided with a through opening that is adapted to the square connecting plate 18, so that the round long rod 16 can move more smoothly to avoid jamming. At the same time, the square connecting plate 18 can move normally when adjusting the position. The outer surface of each supporting vertical plate 9 is fixedly connected to a group of guardrails 10, and the outer surface of each group of guardrails 10 is fixedly connected to a reinforcement rod 13, so that the protection effect of the guardrail 10 is better. The reinforcement rod 13 can be used to enhance the safety of the guardrail when in use. The front and back of the right branch box 2 are fixedly connected with a U-shaped handle 3, which can facilitate the adjustment of the guardrail and facilitate the adjustment operation.

[0024] The outer surfaces of the left and right support boxes 1 and 2 are fixedly connected with mounting plates 4, and the outer surface of each mounting plate 4 is provided with a plurality of positioning holes 5, which facilitates the installation and fixation of the guardrail and improves the convenience of use.

When the power of the warning light 8 is turned on and it is operated, the warning effect can be enhanced. The upper surface of the left support box 1 is fixedly connected with two guide rails 19, and the interior of each guide rail 19 is slidably connected with a sliding rod 20. The right end of each sliding rod 20 is fixedly connected to the upper surface of the right support box 2. When adjusting the position of the right support box 2, the sliding rod 20 can be slid in the guide rail 19 to prevent the right support box 2 from getting stuck when moving, thereby improving its stability in use.

[0025] The working principle of the present utility model is as follows: when in use, the guardrail is moved to the use position, and according to the width of the construction road, the right branch box 2 and the square connecting plate 18 are pulled by the U-shaped handle 3 to move. The movement of the square connecting plate 18 can lead the sliding plate 15 to slide on the smooth column 14, so that the position of the right branch box 2 can be adjusted. At the same time, the movement of the right branch box 2 and the column 11 can lead the protective L-shaped connecting plate 23 and the square slide 22 to move, so that the square slide 22 slides on the long column 21 to ensure safety during adjustment. When the right branch box 2 and the column 11 are adjusted to the appropriate position, the sliding plate 15 can slide along the strip opening 6 with the round long rod 16 when moving, and the locking nut 17 can be tightened to limit the adjusted position, and then the guardrail is installed in the use position using the mounting plate 4 and the positioning opening 5. The guardrail 10 and the protective L-shaped connecting plate 23 can be used to protect roads of different widths.
