Anti-seismic flexible passive protecting screen system for side slope

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.

Description

technical field [0001] The invention relates to a protection net system, in particular to a side slope anti-seismic flexible passive protection net system which can be placed under the side slope and used for protection against falling rocks and rolling stones on the side slope. Background technique [0002] At present, in order to ensure the safety of broken rock slopes, passive protective nets are often deployed under the slopes to protect rockfalls, rolling stones and shallow collapses on rock slopes caused by weathering, rain or vibration. However, the existing passive protection forms mainly use metal mesh and steel cable anchors for slope protection. When the speed of falling rocks, rolling stones and shallow collapse caused by vibration is relatively high, a large impact load will be generated on the passive protection net. It is easy to cause the diamond-shaped steel rope net of the passive protection system to be broken, endangering the safety of the buildings below...

AI Technical Summary

Problems solved by technology

However, the existing passive protection forms mainly use metal mesh and steel cable anchors for slope protection. When the speed of falling rocks, rolling stones and shallow collapse caused by vibration is relatively high, a large impact load will be generated on the passive protection net. It is easy to cause the diamond-shaped steel rope net of the passive protection system to be broken, endangering the safety of the buildings below the slope

If a damping and anti-seismic device is added to the existing passive protection net, the protection ability of the passive protection net can be effectively improved, which is of great significance to the safety of slope protection and surrounding buildings. There is still no such device at present.
