[0002] In the field of geological disaster prevention, landslides, debris flows and other disasters occur frequently, posing a great threat to people's life and property safety. Protective screen, as a common means of geological disaster control, plays an important role in stabilizing hillside soil and preventing rock rolling.

[0003] Traditional protective screen has many limitations, and some protective screen cannot adapt to complex geological terrain. For example, in mountainous areas with large terrain undulations and irregular slopes, the fixed shape protective screen is fixed by simple screw fixing method, which cannot closely fit the ground or slope surface, affecting the contact stress between protective screens and reducing the protective effect.

[0004] In addition, since the fixed points of the adjacent connection mechanism of the protective screen are usually opened on the protective screen body, the physical properties of the protective screen material are limited, and when the protective screen is attached to the slope or rock surface, due to the large undulation of the attached surface, it is difficult to ensure that each connection point can achieve ideal stability. Therefore, the design of the connection mechanism lacks flexibility to deal with undulating surfaces, and the connection is poor, and the connection is difficult to adapt to undulating changes, resulting in unstable stress at the connection.
