It is stretched to before default pulling capacity step by step further include:
0.1-0.2 times of anchor cable axial tension value is taken, to anchor cable pre- tensioning 1-2 times；
1.10-1.20 times of prestress value of ultra stretching is designed to anchor cable.
On the basis of the above embodiments, further, a kind of concrete construction method of steep slope region underloading road structure
Include:
Apply the first anchor pier 4 and the first anchor cable of prestressing force 5: first by the first anchor in one end insertion slopes 3 of the first anchor cable 5
Suo Kongzhong applies anchoring section, and one end of the first anchor cable 5 is fixedly connected with the rock mass stability inside slopes 3；Then by the first anchor
The free end of rope 5 is pierced by the first anchor cable hole, starts to carry out tensioning step by step, it is to be achieved it is default needed for after pulling capacity, anchor cable is carried out
Locking applies the first anchor pier 4, after finally solidifying, wipes out remaining anchor cable part.
The first anchor cable hole deviations are not preferably greater than 20.0mm when the first anchor cable of prestressing force 5 is constructed, and anchor hole degree of skewness is not answered
Greater than 2%, drilling depth is more than that anchorage cable design length is no less than 0.5m.Ying Qingkong before prestress anchorage cable is in the milk, in discharge orifice
Ponding, Grouting Pipe are preferably put into hole with anchor cable simultaneously.Into lateral aperture or the hole that has a down dip when slip casting, Grouting Pipe outlet should be inserted into away from hole
At the 100-300mm of bottom, slurries continuous pouring from bottom to top；In acclivitous drilling when slip casting, sealing dress should be set in aperture
It sets.When aperture overflows slurries or exhaust pipe stopping exhaust and meets slip casting requirement, slip casting can be stopped.
Strength standard value of first anchor cable, 5 control stress for prestressing no more than 0.65 times of steel strand wires.Carrying out formal tensioning
Before, 0.1-0.2 times of anchor cable axial tension value should be taken, to the pre- tensioning of anchor cable 1 time -2 times, keeps the contact at its each position close and bar
Body is totally straight.With the appropriate to the occasion ultra stretching for carrying out 1.10-1.20 times of anchorage cable design prestress value, prestressing force retention, which should meet, to be set
Meter requires.
To stratum and the engineering more demanding by anchor structure Bit andits control, the lock value of prestress anchorage cable is preferably anchor cable axis
To pulling force characteristic value；To the engineering allowing stratum and centainly being deformed by anchor structure generation, the lock value of prestress anchorage cable is preferably

Apply Cantilever Beams 1.The reinforcing bar of Cantilever Beams 1 is bound, formwork erection, casting concrete can between Cantilever Beams 1 and support construction
For riveting, also it is considered as riveting between the first anchor pier 4.
Apply crossbeam 9.Crossbeam 9 can be prefabricated, and prefabricated 9 finished product of crossbeam is mounted on Cantilever Beams 1；It can also show
It pours, binds the reinforcing bar of crossbeam 9, formwork erection, casting concrete according to 9 design requirement of crossbeam on Cantilever Beams 1.
Apply roadbed base plate and supercrust.Piecemeal installs 8 pieces of prefabricated board, carries out overlap joint and stays seam, real on roadbed base plate
Supercrust is applied, has stayed deformation joint in seam crossing correspondence.
Steep slope region provided in this embodiment is lightly loaded road structure form, compared with existing steep slope region road structure form
Advantage is significant: compared with steep slope region parallel contour road structure form, can significantly drop and reduce lower block scale and difficulty, reduces bridge
Beam accounting, advantage is significant in terms of the cubic metre of earth and stone, gear shield quantity of masonry, sign land scale.
Compared with not contour double lower block road structure forms parallel, lower width road supporting and retaining system measure can be saved, bridge is reduced and accounts for
Than advantage is significant in terms of the cubic metre of earth and stone, gear shield quantity of masonry, sign land scale；Compared with midway half-bridge road structure form, advantage
It is more obvious, bridge accounting is directly reduced, investment cost is significantly reduced.
Cantilever Beams 1, prestress anchorage cable and diagonal brace 21 or pier stud 22 are combined together by the road structure, and structure is simple, energy
The enough structure type for adapting to high gradient slope location very well is a kind of novel Steep Slope Embankment landscape road structure form.The road
Structure solves situations such as existing steep slope region can not add landscape road, ride, go slowly, and is a kind of novel framing underloading road
Line structure form.
Compared with traditional retaining structure, the structure type is of less demanding to basic condition, especially has to Steep Slope Embankment
Better adaptability, lightweight are its sharpest edges；Large area earth excavation and the destruction to vegetation are reduced simultaneously, can significantly be saved
Save bricklaying and investment cost.
The road structure closing slope effect is good, can save land used transverse width 1-4m, shortens bridge length 1-2 across comprehensive to survey
It calculates, reduces investment cost at least 10% or more, society and remarkable in economical benefits.In recent years, with highway, the hair of railway engineering
Exhibition dynamics, so that Steep Slope Embankment engineering is significantly increased, which is exactly to be Steep Slope Embankment and research and develop, and has wide application
Prospect.
Mountain area steep slope region creates landscape road, rides, goes slowly, and has that land area is big, cutting brush slope is high, road
Dike bankets the predicament of high, upper lower block measure weight, is limited the limitation of existing supporting and retaining system measure closing slope ability, it is difficult to well solve above-mentioned
Difficulty, and the new road structure type can be perfectly suitable for steep slope region, overcome above-mentioned difficulties, have and use well
Prospect.It reducing construction land simultaneously, reducing the geological disasters sides such as construction investment, reduction soil erosion, reduction landslide
Face effect is obvious.
In conclusion the road structure formal technique is advanced, applied widely, society and remarkable in economical benefits have good
Good popularization and application foreground and social economic value.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
