Wherein, catch net panel region, by arranging many parallel support ropes of varying number and spacing, reaches and improves overall structure protection energy level and the needs reducing structure maximum deformation quantity.Intermediate parallel supporting rope wears extension mutually with interception mesh sheet, and is supported in the middle part of column, and two ends are overhanging and be anchored on bearing.Parallel support rope all can arrange energy-dissipating device.
Further, the described distance descended most between root parallel support rope and ground, needs according to surveying situation design practically, and open height should allow a certain size after being blocked, to fall to open space with the falling rocks of quantity, and runs downwards and enters mesh sheet region of trailing; Or the little energy level to run along certain track, small size falling rocks directly by open space, enter hangover mesh sheet region.And this open height can not be excessive, full load (especially when large volume or large quantity rock-fall impact), effectively should be able to tackle falling rocks, make it to be controlled in catch net panel region, can't continue to move downward, to reach protection object.
Again further, described hangover mesh sheet upper end directly sew be connected to interception mesh sheet lower end, region, because the falling rocks of the certain volume be blocked rebounds after contacting to earth, or first motion to the small size falling rocks of open space possesses certain initial velocity, this part falling rocks is after passing through lower openings space, rolling friction between mesh sheet and ground, dissipation kinetic energy.Thus, the placement length of mesh sheet of trailing should design according to this part kinetic energy dissipation demand.The effusion speed of final falling rocks should meet the demands, to avoid causing secondary disaster.
Survey situation practically, meet management and control requirement, anchor system can be set in local if desired, limit the falling rocks motion in this region further.
It should be added that, many parallel support ropes in the present invention, end supporting rope all can arrange energy-dissipating device according to protecting energy level demand with drawing on anchor line.Many parallel support ropes according to required energy level adjustment quantity and spacing, can be not limited to a kind of arrangement.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention can, according to actual conditions, allow quantity falling rocks on a small scale tackling or slowing down rear by system, to reach the effect of easy to clean.
(2) the present invention is when meeting with fully loaded or extensive falling rocks, effectively can tackle, make it to be controlled in internal system, avoids secondary disaster occurs.
(3) the present invention is to the falling rocks occurred in hangover mesh sheet overlay area, has the effect of track management and control and deceleration buffer.
(4) the present invention is by setting up the mode of many parallel support ropes, improves structural defenses energy level and falling rocks intercept distance, expands the scope of application in Practical Project.
