Problems solved by technology
[0003] Existing foundation pit guardrails are usually built with channel steel or trusses, and these channel steels are welded into a whole through welding operations. The installation of foundation pit guardrails is not only costly, but also takes a long installation period, which seriously affects roads. In the construction project, after the construction is completed, the protective fence of the foundation pit will be destructively dismantled and discarded, and the protective fence cannot be reused, resulting in a waste of resources. Based on this, the present invention proposes a reusable and easy-to-install municipal road with safety guards

The invention discloses a safety protection device for municipal roads, which comprises a connecting column and a plurality of shielding plates connected to each other, the shielding plate at the starting end is rotatably connected with the connecting column, and the plurality of the shielding plates pass through two of the shielding plates. The link mechanism arranged on the side can be unfolded and folded synchronously. The protective device in the present invention adopts three protective plates to be connected through a link mechanism, and the link mechanism includes two Z-shaped connecting pieces, a long connecting rod and an L-shaped connecting piece, and all the protective plates are connected by connecting rods arranged on both sides The mechanism can be unfolded and folded synchronously, the installation is convenient, time is short, labor input is low, and it can be reused, effectively saving social resources.
Description
technical field [0001] The invention relates to the field of urban engineering construction, in particular to a safety protection device for municipal roads. Background technique [0002] With the development of municipal engineering, municipal engineering often needs maintenance and construction. There is a high probability of foundation pit excavation during maintenance and construction. Since the municipal facilities on the side are still in normal use when the foundation pit is excavated, it is necessary to excavate the foundation pit. Foundation pit protection, municipal road foundation pit protection engineering refers to municipal road projects such as the excavation depth of more than 5m, although the foundation pit does not exceed 5m, but the geological conditions and surrounding environment are complex, and the excavation depth exceeds the groundwater level. In the project, the foundation pit protection device is to ensure the safety of the construction of the unde...
