Unfavorable geologic body in, Foundation Pit of Abutment excavation will face the technical barriers such as the large deformation of high thrust unfavorable geologic body, unstable failure.If
Unfavorable geologic body is reinforced using large-diameter bored pile, work progress Zhou Jiyi is influenced by level of ground water and geologic body high thrust,
The construction risk of manually digging hole is very big；According to large diameter drill hole pile, under the effect of unfavorable geology high thrust, large diameter borehole
Stake faces lateral compression, and pore-forming is difficult.Therefore, there is an urgent need for proposing a kind of new structure to solve above-mentioned problem, meet close to abutment
Bedding rock sloper builds abutment, abutment has the requirements such as safe and reliable, easy for construction, investment reduction.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of anchored frame formula brills close to abutment bedding rock sloper
Hole pouring pile reinforcing construction, effectively to solve securely and reliably to build abutment, abutment in level of ground water height, high thrust unfavorable geologic body
Technical barrier.
Technical solution used by the utility model solves above-mentioned technology is as follows：
The anchored frame formula cast-in-situ bored pile reinforcing construction close to abutment bedding rock sloper of the utility model, it is characterized in that：
It is included in above separate abutment side the heel row cast-in-situ bored pile of longitudinally spaced setting in unfavorable geologic body, on abutment side
In square unfavorable geologic body the front-seat cast-in-situ bored pile of longitudinally spaced setting and positioned at heel row cast-in-situ bored pile, preceding row hole drilling fill
Note stake top and therewith rigidly connected Vierendeel girder；In the longitudinally spaced laying anchor cable in heel row cast-in-situ bored pile rear, each anchor cable
Rear portion is anchored in stable Rock And Soil through unfavorable geologic body, and front end is anchored in the top of heel row cast-in-situ bored pile.
The beneficial effects of the utility model are that can resist the big of unfavorable geologic body using the double cast-in-situ bored pile of frame-type pushes away
Power acts on, and the rigidity of structure is big, and holistic resistant behavior is good and front-seat, heel row cast-in-situ bored pile compatible deformation is good；Anchor cable, then can be effective
Reduce the moment of flexure of cast-in-situ bored pile, make up the shortcomings that round stake anti-bending strength is poor and control displacement at pile top.On the other hand, using drilling
Bored concrete pile, the problems such as can effectively solve the problem that phreatic high, high thrust unfavorable geologic body excavated by manual work stake risk, construction efficiency is high,
There is structure novel, safe and reliable, investment reduction, construction is simple.
Description of the drawings
This specification includes following two width attached drawing：

Specific embodiment
The utility model is further illustrated below by specific embodiment and with reference to attached drawing.
With reference to figure 1 and Fig. 2, the anchored frame formula cast-in-situ bored pile close to abutment bedding rock sloper of the utility model reinforces structure
It makes and is included in above separate abutment A sides the heel row cast-in-situ bored pile 1 of longitudinally spaced setting in unfavorable geologic body D, in close to abutment A
The front-seat cast-in-situ bored pile 2 of longitudinally spaced setting and positioned at heel row cast-in-situ bored pile 1, front-seat in unfavorable geologic body D above side
2 stake top of cast-in-situ bored pile and therewith rigidly connected Vierendeel girder.In the longitudinally spaced laying anchor cable in 1 rear of heel row cast-in-situ bored pile
5, the rear portion of each anchor cable 5 is anchored in stable Rock And Soil through unfavorable geologic body D, and front end is anchored in the top of heel row cast-in-situ bored pile 1
Portion.Anchor cable and frame-type cast-in-situ bored pile are combined, using the advantages of redundant structure rigidity is big, overall performance is good, effectively
Solve that water level located underground is high, abutment, the technical barrier of abutment constructional difficulties in high thrust unfavorable geologic body, and with safety
Reliably, the features such as investment reduction, construction is simple.
Referring to Figures 1 and 2, the Vierendeel girder is included respectively along front-seat cast-in-situ bored pile 2,1 longitudinal direction of heel row cast-in-situ bored pile
The front-seat longeron 4a, the heel row longeron 4b that continuously set and it is arranged at laterally corresponding heel row cast-in-situ bored pile 1, preceding row hole drilling
