Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a foundation pit protection device for highway construction. Background Art

[0002] During the construction of highway projects, it is necessary to dig foundation pits. After the foundation pits are dug, they need to be safely protected. On the one hand, it protects the foundation pits, and on the other hand, it avoids the danger caused by pedestrians entering the foundation pits.

[0003] The existing foundation pit safety protection devices are simply designed, generally using a simple combination of simple brackets and mesh layers. Generally, there will be an advertising board with the name of the construction company fixed on the mesh layer. When the mesh layer is reversed, the content of the advertising board faces the position of the foundation pit. At this time, it is necessary to manually re-position and install the mesh layer again, increasing the workload of workers. Secondly, the simple brackets and mesh layers in the existing technology are set in two parts, and they need to be carried and assembled separately during the handling process, increasing the workload of workers. For this reason, we propose a foundation pit protection device for highway construction. Content of the Utility Model
