[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines and equipment. Among them, building construction refers to engineering with roof, beams, columns, walls, foundation and internal space that can meet people's needs for production, living, learning and public activities.

[0003] In existing construction projects, foundation pits or other pits are often dug in the ground. Without barriers, workers may fall into them. Therefore, multiple barriers need to be placed on the sides of the foundation pit or pit to warn workers not to continue walking. Existing barriers are heavy and require screws for installation, making them inconvenient to move and time-consuming to install. Therefore, we propose a barrier device for construction projects.
