Abstract

The present invention is rockfall preventing method and flexible rockfall guiding and preventing net. The flexible rockfall guiding and preventing net with width greater than the protected section and sufficient height for stopping rockfall and guiding the rockfall to safety position is suspended with uprights in the protected area. The net has the upper edge suspended to the uprights and the lower end opening drawn to the massif to guide the rockfall to required position. The net has parts capable of moving with the shock of rockfall to produce corresponding deformation, and has position limiters set on its two sides. The present invention may be used widely for various kinds of rockfall preventing engineering for montanic railway, highway and building.

Description

technical field

[0001] The invention relates to a rockfall preventing method and device, in particular to a rockfall preventing method and a drag-guided rockfall preventing flexible net. technical background

[0002] Rockfall on hillsides will cause serious harm to cliffs, railways, highways, villages and buildings beside slopes. People prevent rockfall hazards with active protective nets and passive protective nets for this reason. The active protection net is to cover the slope with potential geological disasters with a metal flexible net fixed by a wire rope anchor or a steel anchor and a support rope, so as to achieve slope reinforcement or limit the range of rockfall movement. The passive protection net is to install the metal flexible net on the slope at a certain angle by means of fixing methods such as anchor rods, steel columns, support ropes and anchor ropes, forming a fence-shaped rock-blocking net, so as to realize protection against falling rocks and debris flu...
