A kind of suspension type Double-layer flexible shed tunnel, comprise the steel frame connected and composed by steel column and girder steel, wherein, steel column is arranged at highway side, girder steel one end is connected with steel column, the other end is connected with the domatic of steel column opposite side, the two-layer flexible protective stratum reticulare arranged up and down is provided with in end, described steel column upper end, flexible protective stratum reticulare two ends are connected with steel column and the domatic of steel column opposite side respectively, wherein, upper strata flexible protective stratum reticulare and domatic link position are higher than the link position of itself and steel column, lower floor's flexible protective stratum reticulare and domatic link position are then lower than the link position of itself and steel column.
In order to improve protection effect, described flexible protective stratum reticulare is connected with domatic by anchor pole, and is also connected with between anchor pole and steel column and draws anchor line.
Preferably, the link position of two sheets of flexible protection stratum reticulare and steel column is in same level.
Further, be also provided with intercolumniation by anchor pole between steel column top end and ground and draw anchor line, described steel column is provided with some along trend of road, and the intercolumniation between adjacent steel column draws anchor line to combine formation " V " font.
Specifically, described flexible protective stratum reticulare comprises annular or grid stratum reticulare as protecting main body, is arranged on annular or the perimeter support rope of grid stratum reticulare periphery for preventing it from collapsing.
Preferably, the angle between described steel column and girder steel is acute angle.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model adopt large span steel framed structure again in conjunction with flexible protective stratum reticulare as safeguard, compared with prior art, good looking appearance, cost obviously reduces, and it is little to conduct oneself with dignity, to foundation bearing capacity require lower; Hangar tunnel construction period, the blockage effects to traffic was little, and construction is fast, as usual can construct, not need curing time, do not need large-area foundation excavation, both protected natural, ecological, also protect massif in sleet sky; On the other hand, main member of the present utility model is easily dismantled and is changed, and facilitate later stage falling rocks cleaning and safeguard, the location being particluarly suitable for execution conditions complexity uses.
(2) the utility model adopts two sheets of flexible protection stratum reticulare, and protection energy level is high, and first falling rocks drops down onto the protection stratum reticulare on upper strata, by protecting the distortion dissipation rock-fall impact energy of stratum reticulare, and guides falling rocks from side direction landing, without the need to cleaning; Lower floor's protection stratum reticulare plays multilayer proofing guarantee, adds the reliability of protector.

Fig. 2 is structural representation two of the present utility model.
Reference numeral title corresponding in accompanying drawing is as follows: 1-steel column, 2-girder steel, 3-flexible protective stratum reticulare, 4-anchor pole, and 5-draws anchor line, and 6-intercolumniation draws anchor line, 7-hinged-support, 8-concrete foundation;
31-annular or grid stratum reticulare, 32-perimeter support rope.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.Embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, present embodiments provide a kind of suspension type Double-layer flexible shed tunnel, it adopts the steel framed structure of large span to coordinate flexible protective stratum reticulare, guide falling rocks from side direction landing, drastically increase protection energy level, and facilitate the cleaning of falling rocks, be especially applicable to the road prevention below cliff.
Steel frame is connected and composed by steel column 1 and girder steel 2, and specifically, steel column is vertically mounted in the concrete foundation 8 on ground, and its installation site is relative with domatic.End, steel column upper end is connected with the end, one end of girder steel by hinged-support 7, the other end of girder steel by anchor pole 4 be connected to domatic on, preferably, the angle between girder steel and steel column is acute angle.Steel column is furnished with some along the trend of road, and the spacing between adjacent steel column is even, and accordingly, the quantity of girder steel also should be consistent with steel column.Also be provided with intercolumniation by anchor pole between steel column 1 top end and ground and draw anchor line 6, on this basis, be also provided with intercolumniation by anchor pole between steel column 1 top end and ground and draw anchor line 6.
Further, the present embodiment is provided with the two-layer flexible protective stratum reticulare 3 arranged up and down in end, steel column 1 upper end, specifically, flexible protective stratum reticulare 3 comprises annular or grid stratum reticulare 31 as protecting main body, is arranged on annular or the perimeter support rope 32 of grid stratum reticulare 31 periphery for preventing it from collapsing.Two sheets of flexible protection stratum reticulare plays Double-protection effect, and protection energy level is high.
The concrete set-up mode of flexible protective stratum reticulare is as follows: flexible protective stratum reticulare 3 two ends respectively with domatic connection of steel column 1 and steel column 1 opposite side, wherein, upper strata flexible protective stratum reticulare 3 and domatic link position are higher than its link position with steel column 1, and lower floor's flexible protective stratum reticulare 3 and domatic link position are then lower than the link position of itself and steel column 1.Flexible protective stratum reticulare 3 is connected with domatic by anchor pole 4, and is also connected with between anchor pole and steel column 1 and draws anchor line 5, and the angle of inclination of anchor line of drawing of upper end is not less than 50 °.Preferably, two sheets of flexible protection stratum reticulare 3 is in same level with the link position of steel column 1.The open-shaped state of two sheets of flexible protection stratum reticulare, the set-up mode that its two ends are one high and one low, successfully can guide to side landing by the falling rocks falling thereon, avoids piling up.
Operating principle of the present utility model is as follows: when falling rocks tumbles to upper strata, flexible hangar tunnel top protection stratum reticulare from massif, protection stratum reticulare is by distortion dissipation rock-fall impact energy, and guiding falling rocks from side direction landing, falling rocks can not be deposited in above hangar tunnel, avoids the secondary disaster that rock-drop accumulations causes.If upper strata protection stratum reticulare is ruined, damage, then protects stratum reticulare by lower floor and be responsible for keeping out falling rocks, play the effect of Double-protection.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
