Description
Technical field
The present invention relates to a kind of mountain highway rockfall hazards Treatment process, particularly relate to a kind of rockfall quick draining structure for mountain highway protection.
Background technology
Mountain highway as the important component part of highway in China net, is promoting comprehensive exploitation of mountainous areas, is improving the aspects such as mountain area trip condition and played important function；Mountain highway geological disaster in recent years takes place frequently, serious threat is passed through safety, especially it should be noted that, Rolling Stone is as one of big geological disaster in mountain area three, its distribution is the widest, Burst frequency is high, the various structures in its damaging range, mankind's activity is caused great potential safety hazard, it has also become the another big geological disaster after landslide, avalanche, mud-stone flow disaster.
So-called Rolling Stone refers to, indivedual block stones are because certain reason is after side slope and cliff surface unstability, through whereabouts, resilience, jump, roll or the combination of one or more in the motion mode such as slip is along domatic downward rapid movement, the last static dynamic process got off near shallower area or barrier, when the facility having mankind's activity or the mankind to construct in Rolling Stone range of movement and when causing certain loss, just constitute rockfall hazards.The accident that rockfall injures pedestrian by a crashing object, block the traffic is the most startling, and such as evening on May 5th, 2002, in Mian Zhu border of the county, Sichuan, a motor bus is impacted by rockfall at Bao Zhulu, and on car, in 41 passengers, dead 14 people of 18 people are injured；On and for example August 18 calendar year 2001, western ten thousand highway Qinling Mountains Duan Gaopo Rolling Stones tumble from the mountain of more than 50 meters high, and Rolling Stone hits the left side postmedian of a bus, on car 2 passenger's same day dead 6 passengers sustain a severe injury；Mountain highway rockfall disaster occurs again and again, and personnel and vehicle to road operation constitute serious threat, therefore carry out mountain highway rockfall casing pipe protection engineering imperative.
Currently, relating to the technology that mountain area rockfall disaster prevention administers mainly has two kinds, and one is active defense, as remove crag, anchor, support, inlay, active network reinforcing etc.；Another kind is passive protection, such as passive net, stone falling channel and hangar tunnel etc.；It is, in general, that precipitous high mountain gorge mainly risen in by Rolling Stone, extremely difficult to implement its construction of active defense, in Practical Project, rockfall hazards is protected by many employing passive protection measures, and wherein shed hole structure is one of more effective protection works；But hangar tunnel is mainly consumed energy by the sand-gravel cushion of structural top and resists Rolling Stone impact, due to by Rolling Stone percussion, the structure life-span is shorter, need periodic maintenance, and Rolling Stone and chip are easily banked up and deposited in ceiling, practical situation, it is difficult to alluvial be drained at the Rolling Stone of ceiling the most rapidly, cause shed hole structure to bear bigger load for a long time, affect the structure life-span further.
Summary of the invention
For the problem in background technology, the present invention proposes a kind of rockfall quick draining structure for mountain highway protection, including mountain highway, the inner side of described mountain highway be side slope, outside be zanjon, its innovation is: described rockfall quick draining structure by leading stone ladder, lead stone net and bracing frame forms；The described profile leading stone ladder is reclinate arc, and the height of arc the inner is the highest, and the height of arc outer end is higher than the minimum point of arc；Lead be provided with on stone ladder upper side with lead stone ladder trend mate lead stone cistern；Lead stone terraced across above mountain highway, lead stone ladder the inner and be connected with the edge, upper end of mountain highway inslope, lead stone ladder outer end and extend to outside mountain highway；Support frame as described above upper end is connected with leading stone ladder bottom, and bracing frame lower end is connected with the roadbed of mountain highway both sides；Described to lead the Rolling Stone hidden danger district that stone net is arranged in side slope peripheral, and leading stone net is funnel-form distribution, and the bottom of funnel is provided with breach, and breach connects with leading stone cistern.
The principle of the present invention is: will be led stone ladder by the present invention program, be led stone net and bracing frame arranges and deals with problems arising from an accident, under normal circumstances, vehicle is current from leading below stone ladder, when there is rockfall hazards, the Rolling Stone of landing can roll into lead under the stop leading stone net and guide effect leads in stone cistern on stone ladder, then under the guide effect leading stone cistern, the zanjon that Rolling Stone will be thrown to outside mountain highway, thus avoid Rolling Stone to fall on highway, and Rolling Stone also will not deposit on safeguard structure, it is ensured that safeguard structure is permanently effective；It addition, in the present invention, Rolling Stone is gradually to be rolled into lead on stone ladder, and Rolling Stone is the most relatively small to the moment impact of safeguard structure.
Preferably, the described cross section leading stone cistern is spliced by the arc section of two indents, the minimum point led on stone cistern cross section is designated as midpoint, the center of circle of the arc section in left side is positioned on the right side of the level at midpoint, the center of circle of the arc section on right side is positioned on the left of the level at midpoint, and two arc section radiuses are identical, mutually symmetrical with.
Preferably, described in lead stone cistern surface configuration and have an a plurality of resistance to roll flute, the bearing of trend of resistance to roll flute mates with leading stone cistern trend；The anchoring of wall scroll wear-resisting tooth surface has a plurality of abrasion-resistant metal body, and the bearing of trend of abrasion-resistant metal body mates with the bearing of trend of resistance to roll flute, and a plurality of abrasion-resistant metal body is circumferentially distributed along wear-resisting tooth.Resistance to roll flute with abrasion-resistant metal body can effectively reduce the abrasion caused because of Rolling Stone friction, improves the structure life-span, is the most also more conducive to Rolling Stone and rolls.
Preferably, described abrasion-resistant metal body uses waste and old steel rail to make.The abrasion-resistant metal body using waste and old steel rail to make, in addition to can playing aforesaid anti scuffing effect, also makes waste and old steel rail be utilized.
Preferably, the cross section of described resistance to roll flute is trapezoidal, trapezoidal upper side, left surface and right flank are each provided with an abrasion-resistant metal body.
Preferably, lead stone net described in and use SNS soft protecting net.
Preferably, the minimum point of described arc is designated as B point, and point corresponding to arc outer end is designated as C point, on arc, the section between C point and B point is designated as reflex action section, reflex action section is circular arc, and the center of circle of circular arc is positioned at directly over B point, and between C point and B point, line is 8 ~ 10 degree with the angle of horizontal direction.Experiment proves that, compared to other angles, after using this improvement project, Rolling Stone can be thrown farther.
The method have the benefit that: the protection effect to rockfall hazards can be significantly improved, it is to avoid Rolling Stone is piled up on safeguard structure.
