Description

Technical Field

[0001] This utility model relates to the technical field of slope construction protection equipment, specifically a safety protection device for high slope excavation projects. Background Technology

[0002] In recent years, with the rapid development of infrastructure projects, a large number of steep slopes have been formed during modern engineering, especially tunnel excavation and high slope excavation in factory areas. The slope surfaces of these steep slopes are usually exposed, and the rock composition of the overlying layer is mostly gravel and sandy loam. During the rainy season, rainwater erosion of the slope surface is quite severe, leading to serious soil erosion. Furthermore, long-term erosion of the slope surface by rainwater can easily cause disasters such as mudslides and landslides. Therefore, it is particularly important to design and develop protective structures for steep slopes to reduce the erosion of the slope by rainwater.

[0003] However, existing protective nets are fixed with bolts, making them difficult to disassemble and replace after damage, thus reducing the maintenance efficiency of workers. Furthermore, the protective fences are not easy to splice together, which reduces the installation efficiency of workers. Utility Model Content

The guardrail base has a sliding cavity, in which two sliding blocks are slidably arranged. Two support columns are respectively installed on the top of the two sliding blocks. The support columns have multiple T-shaped insertion slots with top openings. T-shaped insertion strips are installed at both ends of the protective net, and the protective net is connected to two adjacent support columns through the T-shaped insertion strips. Mounting seats are installed on both sides of the guardrail base, and two symmetrical ground nails are slidably installed on the mounting seats.
