DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , a spliced guardrail for municipal engineering, including an anti-crossing railing 3. Columns 1 are arranged on both sides of the anti-crossing railing 3. An inner column 2 is slidably arranged inside the column 1. A support bar 4 is arranged between adjacent anti-crossing railings 3. Limiting grooves 101 are arranged on the outer walls around the column 1 for limiting the anti-crossing railing 3. Through holes 103 are arranged on both sides of the limiting groove 101. The anti-crossing railing 3 is fixedly connected to the limiting groove 101 through a locking screw 104. The two ends of the anti-crossing railing 3 are respectively inserted into the limiting groove 101 to realize the limitation of the anti-crossing railing 3, and the locking screw 104 passes through the through hole 103 and is fixed to the anti-crossing railing 3 to realize the limiting fixation of the anti-crossing railing 3. This limiting fixation method is convenient for the splicing and replacement between the column 1 and the anti-crossing railing 3. By arranging the limiting grooves 101 on the outer walls around the column 1, the space can be divided according to the area to be protected, and different functional areas can be separated. The anti-crossing railing 3 can also be increased or decreased according to the range to be protected, which is relatively flexible in use and simple and fast to splice.

[0020] Furthermore, positioning holes 201 are arranged on the outer walls around the inner column 2. The column 1 is fixedly connected to the positioning holes 201 of the inner column 2 through positioning pins 102. By adjusting the height of the inner column 2, the height of the entire column 1 can be increased. A cross bar 5 is arranged between adjacent inner columns 2, and both ends of the cross bar 5 are located in the positioning holes 201. The cross bar 5 is connected to the positioning holes 201 in an inserted manner. The splicing method is simple and fast. The positioning holes 201 can not only realize the connection with the cross bar 5 but also be fixed to the column 1 through the positioning pins 102, with strong applicability. The cross bar 5 plays a role in isolation. By adjusting the height of the entire guardrail, the willingness of pedestrians to cross the guardrail can be reduced, thereby effectively reducing the interference behavior of pedestrians in the protected area.

[0021] Furthermore, clamping grooves 401 are arranged at the upper and lower ends of the support bar 4, and the clamping grooves 401 are connected to the anti-crossing railing 3 in a clamping manner. The support bar 4 plays a supporting role for the anti-crossing railing 3 and improves the service strength of the anti-crossing railing 3.

[0022] Furthermore, threaded grooves 301 are provided at both the upper and lower ends of the anti-climbing rail 3. An anti-climbing rod 302 is threadedly installed inside the threaded groove 301. The anti-climbing rod 302 can prevent pedestrians from climbing over the upper end of the guardrail or through the gap between two adjacent anti-climbing rails 3. The threaded installation method facilitates the quick fixation of the anti-climbing rod 302.

[0023] Working principle: For a spliced guardrail for municipal engineering of the present utility model, during use, the support rod 4 is connected to the anti-climbing rail 3 through the card slot 401 to achieve support. Then, both ends of the anti-climbing rail 3 are respectively inserted into the limit slots 101 of the upright posts 1 to achieve the limitation of the anti-climbing rail 3. The locking screw 104 is passed through the through hole 103 to be fixed to the anti-climbing rail 3, realizing the limit fixation of the anti-climbing rail 3. The anti-climbing rails 3 and the upright posts 1 can be increased or decreased according to the protection range. Then, by adjusting the height of the inner column 2 and connecting the cross bar 5 to the inner column 2 in a plug-in manner, the height of the entire guardrail can be increased, which can reduce the willingness of pedestrians to climb over the guardrail, thereby effectively reducing the interference behavior of pedestrians in the protected area. By quickly fixing the anti-climbing rod 302 by means of threaded installation, it can effectively prevent pedestrians from climbing over the upper end of the guardrail or through the gap between two adjacent anti-climbing rails 3.
