Field.
Background technique
To avoid high gradient slope Rolling Stone from damaging highway, ensures the security of the lives and property of vehicular traffic and personnel, lead to
Reinforcing bar protective net is often set in side slope, but when the momentum of Rolling Stone is larger and there is spring situation in dropping process, the steel
The protective action of muscle protective net is limited.Secondly, also there is the side for taking and building hangar tunnel protection vehicular traffic and pedestrian above highway
Method, hangar tunnel are divided into rigid hangar tunnel and two kinds of flexible hangar tunnel according to structure type, reinforcing bar protective net are mostly used at the top of flexible hangar tunnel,
Although reducing engineering cost to a certain extent, protective action only is played to Rolling Stone impact, to the side for thering is mud-rock flow to occur
The effect on slope, flexible hangar tunnel is limited.What application was more at present is rigid hangar tunnel, i.e. armored concrete hangar tunnel, relies primarily on top
The native rock ballast buffer layer in portion reduces the momentum of Rolling Stone.It is learnt according to physics principle and rockfall simulation softward, to have
Effect reduces the Rolling Stone momentum of shed tunnel top, and the thickness of buffer layer is about 1.5 meters, and buffer layer is from great, and buffering effect is poor, to hangar tunnel
Force structure require high, cause hangar tunnel project cost high.Therefore, a kind of safety coefficient height need to be sought, buffer layer quality is small, and
The relatively low shed hole structure of project cost.

Specific embodiment
Technical solution of the present invention is further described below with reference to the attached drawing in embodiment, but claimed range is not
It is confined to described.
As shown in Figure 1, a kind of ecological shed hole structure for protecting high gradient slope to get down the highway of the present invention, including canopy
The support system of hole structure bottom and the guard system on top, the support system include barricade 1, column 2, top plate 3, crossbeam 4
With stringer 5；
The lower part of side slope 18 is arranged in the barricade 1, and the bottom of barricade 1 extends to ground, and the column 2 has several,
Along the longitudinally disposed of hangar tunnel, the stringer 5 is arranged between two adjacent columns 2 several columns 2, and stringer 5 is positioned at vertical
The top of column 2, the column 2 are connect by crossbeam 4 with barricade 1, and the top plate 3 is arranged on barricade 1 and stringer 5.Support system
System is used to support entire shed hole structure, must have certain intensity, overall stability and shock resistance, guard system is mainly used
In the momentum for reducing Rolling Stone or mud-rock flow, support system is protected；In construction, column 2 is mounted on upright post basic 12, and several
For column 2 along longitudinal equidistantly distributed of hangar tunnel, barricade 1, column 2, crossbeam 4, top plate 3 and stringer 5 are concrete structure, can be with
One-time-concreting molding, has been effectively ensured the intensity and impact resistance of support system, barricade 1, column 2, crossbeam 4 and stringer 5 it is upper
End face in the same plane, makes them play a supporting role top plate 3.
The ecology shed hole structure further includes drainage system, which includes massif drainpipe 14 and gutter 17,
Gutter 17 is arranged between highway 13 and barricade 1, and side slope 18 is protruded into one end of massif drainpipe 14, and the other end passes through barricade 1
Extend to 17 top of gutter.Gutter 17 is concrete structure, can be subjected to the impact of water droplet or water flow, massif for a long time
Drainpipe 14 stretches out the suitable length of barricade 1, can directly fall to after flowing out water droplet or water flow out of massif drainpipe 14
In gutter 17, the ponding in 18 surface of side slope and side slope 18 can be discharged in gutter 17 by massif drainpipe 14 in time, be passed through
Outside 17 water conservancy diversion to shed hole structure of gutter, the probability that side slope 18 comes down is reduced.
The top plate 3 is equipped with block 6, and block 6 is located at the side of close column 2, is equipped with drainpipe in block 6
11, which runs through block 6.The length of block 6 and the length of shed hole structure are consistent, are concrete structure, make protection system
System is maintained on the top plate 3 between block 6 and side slope 18, and the material in guard system is avoided to be lost, and drainpipe 11 will be for that will prevent
Ponding in protecting system is discharged into outside shed hole structure, mitigates the weight of guard system, reduces the load of support system.
The water inlet of the drainpipe 11 is equipped with loaded filter 16, and the loaded filter 16 is located in guard system.Loaded filter
16 are located at the side of block 6, and adjacent with block 6, for the ponding in filter protection system, while avoiding in guard system
Fine material is lost.
The guard system is mounted on top plate 3, and between block 6 and side slope 18, the guard system is from bottom to up
It is followed successively by cement sand bed 7, waterproof layer 8, buffer layer 9 and protective layer 10.Guard system is mainly used for reducing Rolling Stone or mud-rock flow
Momentum, protect support system below, support system avoided to bear biggish impact；In addition, the cement in guard system
The main function of screed 7 and waterproof layer 8 is waterproof, avoids the ponding in guard system from flowing through top plate 3 and falls directly on highway 13
On.
The waterproof layer 8 is TQF-1 type waterproof layer.It avoids the water in guard system from flowing through top plate 3 and falls directly on highway 13
On.
The buffer layer 9 is that polystyrene foam particles and undisturbed soil are mixed by the volume ratio of 2:1.Polystyrene bubble
Foam grain density is small, and has good physico mechanical characteristic, mixes with undisturbed soil by the volume ratio of 2:1, is guaranteeing buffering effect
While fruit, the quality of buffer layer 9 is greatly reduced, that is, reduces the overall weight of guard system, in guarantee and just
Property hangar tunnel have same effect under the premise of, the intensity requirement to ecological hangar tunnel structural support system is reduced, to reduce
The project cost of ecological shed hole structure.
The buffer layer 9 with a thickness of 0.8m~1.2m.The buffering effect of buffer layer 9 is effectively ensured, avoids Rolling Stone or mud
Rock glacier causes greater impact to support system.
The protective layer 10 includes organic soil horizon and grass seed mix, and grass seed mix is located at the top of organic soil layer, has
Machine soil horizon with a thickness of 30cm, grass seed mix is made of English ryegrass, Festuca Arundinacea, Bermuda grass and Trifolium repense.Protective layer
10 and 9 shared Rolling Stone of buffer layer or mud-rock flow impact energy, while protective layer 10 avoids buffer layer 9 by rain drop erosion
And it is lost.
Several anchor poles 15 are installed, one end of several anchor poles 15 extends in barricade 1, and extends in the side slope 18
The length of anchor pole 15 in barricade 1 is not less than 0.5m.Anchor pole 15 and concrete guard wall 1 outside side slope 18 pour as entirety, increase
The overall stability of shed hole structure, integral strength and shock resistance.
Embodiment one:
As shown in Figure 1, the main construction procedure of ecological shed hole structure is as follows:
(1) it excavates and slope supported 18, it is ensured that anchor pole 15 is reserved in the length outside side slope 18 not less than 0.5m, reserves massif
Drainage hole；
(2) barricade 1 of side slope side is leaned on concreting, barricade 1 and exposed anchor pole 15 pour as entirety, completion public affairs
The construction in gutter 17 between road 13 and barricade 1, and massif is reserved into drainage hole, gutter is extended to by massif drainpipe 14
17 top；
(3) concreting upright post basic 12, column 2, crossbeam 4, stringer 5, top plate 3 are used, ecological shed hole structure is completed
Main body construction；
(4) concreting block 6 is used, and pre-installs drainpipe 11 in block 6, drainpipe 11 is 50 steel pipe of φ, is being arranged
The water inlet of water pipe 11 is installed by loaded filter 16；
(5) it is sequentially completed applying for cement sand bed 7, waterproof layer 8, buffer layer 9 and protective layer 10 from bottom to up on top plate 3
Work so far completes the integral construction of ecological shed hole structure.
