Problems solved by technology

However, the time, falling point, quantity, speed and movement mode of falling rocks are uncertain, so they are sudden and unpredictable, and falling rocks are often fast and impactful, and the high-speed impact force produced has great impact. Strong destructiveness, it is easy to penetrate the protective net and cause serious harm

Embodiment Construction

[0017] Use section steel uprights (6), the main function of uprights is to open the network opening, the lower part of the uprights is directly fixed on the rock matrix of the mountain body, or the concrete base (11) is set on the mountain body, the lower part of the uprights can be connected with the base through ordinary hinges When the net is impacted by falling rocks, the column swings in a certain plane. The column and the base can also be connected by ball joints. When the net is impacted by falling rocks, the column can swing in multiple directions. The span of the column should be able to basically level the upper edge of the protective net. From a safety point of view, care should be taken to keep the column as far away from the edge of the cliff as possible when installing it. The anchor rope (7) is connected to the top of the column for positioning and reinforcement of the column. The other end of the anchor rope is fixed on the rock of the mountain. For example, i...

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...
