Collapse；The protection network prestressing force that vertically and horizontally supporting rope 2 applies to rock is lost and causes active network to fail.
2nd, passive net：Due to passive net, moderate finite deformation can occur for mesh sheet during falling rocks is intercepted, and passive net sets too
Low, larger buffer distance certainly will injure electrified equipment and train on railway；Passive net sets get Tai Gao, and quilt can not be protected again
Move the domatic falling rocks in portion off the net；Meanwhile, either active network or passively net, intercepted falling rocks are all difficult to clean up, excessive
Accumulation can form potential safety hazard again.
3rd, curtain net：The requirement of curtain sieve bottom has enough falling rocks collecting zones, and does not often possess at the top of tunnel portal
Such condition.
Open cut tunnel, hangar tunnel：Open cut tunnel is very high to fundamental importance, and many engineerings are due to a varied topography, it is impossible to meet this condition,
And to a certain extent for, bright, hangar tunnel impact resistance is limited.

The cross-brace rope set along horizontal slope direction, cross-brace rope one end is connected on support column capital, and the other end is anchored in longitudinal direction
On the massif of supporting rope position, energy consumer is provided with the cross-brace rope；It is connected to longitudinal bracing rope, cross-brace
Interception net on rope, intercepts net and is closed with pasting in longitudinal slope upper end original position and longitudinal side, form flexible longitudinal guide
Domatic and horizontal shunting is domatic.
It is preferred that, the support column both sides are provided with drawing anchor line.
It is preferred that, the drawing anchor line position anchorage point being connected on same support column is higher than cross-brace line anchor maintenance
Put.
It is preferred that, the flexible point guiding systems are symmetrical set, and its axis is arranged along mountain region longitudinal slope, if the Heavenly Stems and Earthly Branches
Dagger is arranged on the axis.
The present invention principle be：It is artificial domatic by building（Longitudinal and transverse two direction）, will be blocked by top curtain net
Cut, the falling rocks after slowing down that consumes energy is intercepted and shunted guiding, falling rocks can only be tumbled to finger in wire side upper direction, and along slope aspect
Positioning is put.
Compared with prior art, the invention has the advantages that：
（1）" guiding " theory of curtain net and the theory of " shunting " are combined by the present invention, have effectively achieved the safety of falling rocks
Guiding and orientation accumulation.System can to mountain region falling rocks, collapse rock, dissipate that soil block etc. carries out shunting guiding and orientation is accumulated, realize pair
Effective protection of target fabrication；
