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, at promotion comprehensive exploitation of mountainous areas, improves in mountain area trip condition etc. and has 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 large geological disaster in mountain area three, its distribution is extremely wide, Burst frequency is high, causes great potential safety hazard to the various structure in its damaging range, mankind's activity, has become the another large geological disaster after landslide, avalanche, mud-stone flow disaster.
So-called Rolling Stone refers to, indivedual block stone is because certain reason is after side slope and cliff surface unstability, the combination of one or more in the motion modes such as whereabouts, resilience, jump, rolling or slip is along domatic downward rapid movement, the finally static dynamic process got off near milder area or obstruction, the facility constructed when having mankind's activity or the mankind in Rolling Stone range of movement also, when causing certain loss, just constitutes rockfall hazards.Rockfall injures pedestrian by a crashing object, the accident that blocks the traffic is startling especially, and as evening on May 5th, 2002, in Mian Zhu border of the county, Sichuan, a motor bus is subject to rockfall at Bao Zhulu and impacts, 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, constitutes serious threat to the personnel of road operation and vehicle, therefore carries out mountain highway rockfall casing pipe protection engineering imperative.
Current, relate to the technology that mountain area rockfall disaster prevention administers and mainly contain two kinds, one is active defense, as removed crag, anchoring, support, inlay, active network reinforcing etc.; Another kind is passive protection, as passive net, stone falling channel and hangar tunnel etc.; In general, precipitous high mountain gorge mainly risen in by Rolling Stone, very difficult to implement its construction of active defense, and in Practical Project, many employing passive protection measures are protected rockfall hazards, and wherein shed hole structure is one of comparatively effective preventive works; But hangar tunnel mainly by the sand-gravel cushion of structural top consume energy opposing Rolling Stone impact, owing to being subject to Rolling Stone percussion, the structure life-span is shorter, need periodic maintenance, and Rolling Stone and chip are easily banked up, alluvial is at ceiling, in actual conditions, is difficult to alluvial be drained at the Rolling Stone of ceiling rapidly in time, cause shed hole structure to bear larger 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, comprise mountain highway, the inner side of described mountain highway is side slope, outside is zanjon, and 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 stone ladder upper side is provided with lead that stone ladder moves towards to mate lead stone cistern; Lead stone ladder 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 with lead stone ladder bottom be connected, bracing frame lower end is connected with the roadbed of mountain highway both sides; Describedly lead stone net to be arranged at Rolling Stone hidden danger district in side slope peripheral, leading stone net be that funnel-form distributes, and the bottom of funnel is provided with breach, breach with lead stone cistern and be communicated with.
Principle of the present invention is: will lead stone ladder by the present invention program, and lead stone net and bracing frame and arrange and deal 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, and stone ladder leads in stone cistern, then under the guide effect leading stone cistern, Rolling Stone will by the zanjon thrown to outside mountain highway, thus avoid Rolling Stone to fall on highway, and Rolling Stone also can not deposit on safeguard structure, ensure that safeguard structure is permanently effective; In addition, in the present invention, Rolling Stone is rolled into gradually to lead on stone ladder, and Rolling Stone is also relatively little to the moment impact of safeguard structure.
Preferably, described cross section of leading stone cistern is spliced by the arc section of two indents, the minimum point led on stone cistern cross section is designated as mid point, the center of circle of the arc section in left side is positioned on the right side of the level of mid point, the center of circle of the arc section on right side is positioned on the left of the level of mid point, and two arc section radiuses are identical, symmetrical mutually.
Preferably, described in lead stone cistern surface and be provided with many resistance to roll flutes, the bearing of trend of resistance to roll flute with lead stone cistern and move towards to mate; The wear-resisting tooth surface anchoring of wall scroll has many strip metals wear body, and the bearing of trend of abrasion-resistant metal body mates with the bearing of trend of resistance to roll flute, and many strip metals wear body is along wear-resisting tooth rim to distribution.Resistance to roll flute with abrasion-resistant metal body effectively can reduce the abrasion because Rolling Stone friction causes, and improves the structure life-span, is also more conducive to Rolling Stone simultaneously and rolls.
Preferably, described abrasion-resistant metal body adopts waste and old steel rail to make.The abrasion-resistant metal body adopting waste and old steel rail to make, except can playing aforesaid anti scuffing effect, also makes waste and old steel rail obtain utilization.
Preferably, the cross section of described resistance to roll flute is that trapezoidal, trapezoidal upper side, left surface and right flank is respectively provided with a strip metal wear body.
Preferably, lead stone net described in and adopt 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, section on arc 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, the angle of line and horizontal direction is 8 ~ 10 degree.Through verification experimental verification, compared to other angles, after adopting this improvement project, Rolling Stone can be thrown farther.
Advantageous Effects of the present invention is: can significantly improve the protection effect to rockfall hazards, avoids Rolling Stone to pile up on safeguard structure.
