Bolt connection makes the installation process cumbersome and time-consuming, and welding requires professional welding technology, which has high technical requirements for construction personnel. After welding, the protection net structure is damaged and has low reusability. Secondly, the flexibility of traditional foundation pit edge protection nets is poor, and the protection effect is not good when facing foundation pits of different sizes and shapes.
