[0002] The development of road and bridge engineering technology is the result of the promotion of transportation demand, the support of technological innovation and the development of infrastructure construction. During the construction of road and bridge projects, in order to avoid pedestrians from mistakenly entering the construction site and causing unnecessary trouble, workers usually need a road and bridge project safety fence.

[0003] After searching, it was found that the patent number CN219138598U discloses a municipal road and bridge engineering safety enclosure device, including a base, two bases are equipped with columns on the top, and the two bases are fixed with fixed spikes on the bottom, which are convenient for improving the stability of the base. The same enclosure plate is installed on the side where the two columns are close to each other, and a groove is opened on the front of the enclosure plate. The first reinforcement rod and the second reinforcement rod are respectively installed in the groove, and a number of anti-collision pads are equidistantly installed on the back of the enclosure plate, which has good anti-collision ability and high practicality.

[0004] However, during the use of the above device, the base is installed by fixing the base through the fixing spikes during installation, but the fixing range of the fixing spikes to the ground is small, and the base is prone to tilt when facing windy conditions, which may cause safety hazards over a long period of time. In view of this, we propose a road and bridge engineering safety enclosure. Utility Model Content
