Description
Technical field
The present invention relates to the hazards control technology, be particularly suitable for a kind of economy that the anti-Rolling Stone of Rolling Stone diaster prevention and control structure impacts, effectively protect new construction.
Background technology
Rolling Stone is in China mountain area, particularly the western mountainous areas highway is seen everywhere along the line, and distribution is extremely wide, and it takes place suddenly, frequency is high, hard to guard against, to various highway structure in its damaging range as highway pavement, bridge, tunnel import and export, open cut tunnel, hangar tunnel etc.; Mankind's activity as: driving vehicle, passing crowd etc. has constituted serious threat, has become the another big geological disaster after landslide, avalanche, mud-stone flow disaster.
In general, the method for preventing and treating of Rolling Stone disaster can be divided into two big classes: initiatively protection and passive protection.Initiatively protection is intended to take measures to stop the unstability of potential Rolling Stone, and passive protection then refers to allow the generation of Rolling Stone, but avoids Rolling Stone to work the mischief.
If the source area scope of Rolling Stone is bigger, the more or slope complicated condition of potential Rolling Stone quantity in addition can't near the time, perhaps halfway Rolling Stone is tackled is a kind of effective safeguard procedures.But prerequisite is to have enough knowledge to motion features such as the motion path of Rolling Stone, jumping height, migration distance, speed, the scopes of being scattered, because these parameters and data are the addressing of Rolling Stone protective equipment and the foundation of structure design.The interception measure of Rolling Stone mainly comprises section stone ditch, stone blocking net, a retaining stone walling, blocks stone fence, open cut tunnel or anti-Rolling Stone canopy etc.
Cut the stone ditch: when on domatic between the source area of Rolling Stone and the zone of protection platform or gentle slope being arranged, can cut a stone ditch at the correct position excavation on platform or gentle slope and tackle Rolling Stone.Natural ditch domatic or that the toe place moves towards direction along side slope is revised the interception that also can be used for Rolling Stone a little.For the Rolling Stone that prevents high-speed motion causes the Rolling Stone disaster from cutting to bounce in the stone ditch to zone of protection, can in cutting the stone ditch, some padded coamings be set, as rubble, chip, soil etc.In addition, retaining stone walling, block, fence etc. can also be set up, to increase its interdiction capability in the outside of cutting the stone ditch.It should be noted that excavation cuts the stone ditch and sometimes the stability of sloping body brought adverse effect.
Stone blocking net: the stone blocking net Rolling Stone entrained energy when impacting this system that can effectively dissipate by the mode such as displacement, distortion, vibration of self.The steel cable that present widely used stone blocking net is mainly used by wire lath sheet, supporting network sheet and steel column, with steel column and sloping body link together hinged, be connected drawing anchor line, drawing the buffering device that is provided with on the anchor line etc. to form in case of necessity of steel column upper end and slope, top body.To stone blocking net can be divided into column block and strut-type block according to the difference of supporting way.For the little side slope of slope angle, can be set to column by stone blocking net.When the abrupt slope is close to upright and zone of protection when narrower (such as being the road that wire is extended), can stone blocking net be set the strut-type mode on cliff.For the comparatively clear and definite cheuch location of Rolling Stone motion path, the steel fabric sheet of stone blocking net can be hung on the horizontal steel cable, simultaneously the steel cable two ends are anchored on the stable basement rock of cheuch both sides with the interception Rolling Stone.
Retaining stone walling: the effect that the retaining stone walling has the interception Rolling Stone and stores up Rolling Stone.The retaining stone walling can be intercepted and captured diameter and reach 1,5～2m with the Rolling Stone that slides or roll mode moves, and can also store the Rolling Stone of some simultaneously, reduces its clearing times.Tackle the effect of Rolling Stone and be convenient to construction and transportation in order to bring into play the retaining stone walling to greatest extent, keep off stone walling and generally build in toe near the zone of protection place.The retaining stone walling that can be used for tackling Rolling Stone has multiple, as steel concrete barricade, gabion baffling, stone masonry barricade etc.Gabion baffling low price and have certain flexibility was used in having of mountain area more difficultly, but bulk strength is lower and wire to be easy to corrosion be its major defect.For this reason, Zhang Luqing etc. have developed a kind of stratified net-mesh reinforced stone-gabion, and have applied for corresponding patent of invention.Novel steel bar stone cage retaining wall has not only kept the major advantage of original gabion baffling, has also increased bulk strength height, wire and has been difficult for corrosion, is easy to many-sided advantages such as greening and monitoring.
Block the stone fence: blocking the stone fence becomes one of main means of China railways systematic protection Rolling Stone because of having advantages such as simplicity of design, easy construction.Block the stone fence and generally do the basis, make column and cross bar with timber or steel (as waste and old steel rail, shaped steel etc.) by mortar flag stone or concrete.By its material difference, block the stone fence and can be divided into wire netting (as the rail fence) and post-and-paling.The rail fence has overcome the shortcoming that retaining stone walling quantity of masonry is big, engineering cost is high.Because the rail fence is a kind of rigid structures, the Rolling Stone that impact energy is bigger can puncture fence sometimes.Owing to reasons such as the convenience of drawing materials, former post-and-paling is used more in the mountain area.Yet the intensity of former post-and-paling is lower and rotten easily, causes it to be difficult to the requirement of shelter that reaches permanently effective.In addition, use log to run counter to environmental regulation in a large number, use is not advocated in suggestion yet.
Open cut tunnel or anti-Rolling Stone canopy: in the location that Rolling Stone often occurs, effectively blocking one of building is exactly open cut tunnel.According to the difference of form of structure, open cut tunnel can be divided into three kinds of common form such as arch open cut tunnel, board-like hangar tunnel and cantilever-type hangar tunnel.The open cut tunnel of three kinds of forms all utilized sloping body or massif as backer's wall or be support.Two abutment walls of arch open cut tunnel bear pressure at right angle and the horizontal thrust that is transmitted by vault and sloping body direction respectively jointly, and board-like hangar tunnel mainly bears above-mentioned load by interior abutment wall.The cantilever-type hangar tunnel is owing to the restriction in place has only inboard abutment wall.When can't be by means of sloping body during as load bearing wall, can construct the anti-Rolling Stone canopy that is independent of sloping body, this also is that anti-Rolling Stone canopy is different from one of reason of open cut tunnel.In the location, mountain area of a lot of difficulties, often can see the anti-Rolling Stone canopy that some utilize log to build, but use log and environmental regulation not to be inconsistent in a large number.
