The device includes a municipal road engineering foundation pit safety protection plate. The transmission structure can adjust the inclination angle of the municipal road engineering foundation pit safety protection plate, allowing the municipal road engineering foundation pit safety protection plate to adapt to different environmental protection effects. The municipal road engineering foundation pit safety protection plate can also enhance the protection range.

[0004] Based on the above retrieval and existing technology, it is found that:

[0005] The existing foundation pit safety protection device mainly uses a single bottom support structure, which has poor stability. When encountering strong winds, vehicle bumps, and other external disturbances, it is prone to shaking or even tipping over, making it difficult to provide continuous and reliable warning around the foundation pit and effectively ensuring the safety of passing pedestrians and vehicles. Moreover, the installation method of the warning component and the support frame is complicated, often requiring a large number of bolts for fixation, which not only consumes the time and effort of construction personnel, but also may delay the construction period in emergency construction scenarios, hindering the efficient progress of the project. In addition, the traditional protection device has inappropriate material selection, is generally bulky, and is extremely inconvenient to move, increasing the construction cost and difficulty.
