Abstract
The invention discloses an anti-seismic flexible passive protecting screen system for a side slope, which comprises a passive protecting screen, a steel column (3), an upper supporting rope (2), a lower supporting rope (4) and an upper anchor pulling rope (11). The anti-seismic flexible passive protecting screen system for the side slope is characterized in that at least one end of the upper supporting rope (2) is connected with the top end of the steel column (3) via an anti-seismic damping component, and the upper anchor pulling rope (11) is connected with the top end of the steel column (3) via another anti-seismic damping component. When the side slope is in earthquake, stones and rocks rolling along the surface of the side slope can generate large impact force to the passive protecting screen, and impact energy can be converted into damping liquid heat energy via the anti-seismic damping components. Impact caused by falling rocks, rolling stones, shallow collapse and the like on the rock side slope when in earthquake to the passive protecting screen can be effectively reduced, and the problem that buildings below the side slope are damaged due to the fact that the passive protecting screen is broken by the falling rocks and the rolling stones is avoided. In addition, the protecting screen system is simple in structure, convenient in manufacture and reliable in performance.
