Description

Technical Field

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

[0002] In foundation pit construction projects, the excavation depth of the foundation pit is usually deep. Therefore, the edge protection of the foundation pit is often a key point in the construction process. Most construction accidents occur because the edge protection of the foundation pit is not in place, the protection effect is poor or the construction is unreasonable.

[0003] Chinese patent application number 201320070313.5 discloses a foundation pit edge guardrail for construction, including at least one guardrail, each guardrail includes a guard frame, a guard net and a support rod, a guard net is arranged inside the guard frame, and the left and right sides of the guard frame are respectively provided with mutually matching pins and pin holes, the bottom end of the guard frame is connected to the support rod by bolts, and each guardrail is connected by the pins and pin holes. The utility model is easy to build by fixing the pins and the pin holes, and is also easy to disassemble. After disassembly, each guardrail can be placed in an overlapping manner, which is not only convenient for transportation and storage, but also can be reused many times. The overall guardrail is beautiful, has a good protective warning effect, saves costs, and is highly practical. However, there are still some shortcomings in the implementation of this patent. When in use, this patent connects to the ground through the base and the mounting holes on the base to fix the guardrail. The stability of the connection is poor. After the connection, when the guardrail encounters strong winds, the guardrail will be blown down by the strong wind, thereby causing certain safety hazards. At the same time, dust will be generated during the construction of the foundation pit. The dust cannot be timely treated for dust reduction, which will cause pollution to the surrounding environment, thereby causing the problem of failure to meet the environmental protection requirements of the construction.
