Landslide disaster.Most easily occur disease, current state for the soil-slope that rock side slope and height that height is less than 30m are less than 20 meters
The engineering technology such as interior usual use friction pile, prestress anchorage cable carry out improvement protection.But there is long in time limit, difficulty in these technologies
Greatly, the self-characteristic such as cost height has limited to promoting the use for technology；Although in addition, mini pile arranges fast and flexible, difficulty of construction
Small, cost is low, but the stress performance and durability of common material mini pile are difficult to the antiskid demand for meeting the larger side slope of sliding force.
The content of the invention
The purpose of this utility model is that offer is a kind of, and simple in construction, easy construction, good mechanical properties are practical
Addition carbon fibre material miniature pilework, the deficiencies in the prior art can be overcome.
To reach above-mentioned purpose, the utility model is achieved using following technical scheme.
The mini pile antiskid structure of carbon fibre material is added, it, which includes running through, is opened on slip stratum and good ground
Mini pile stake holes, is provided with the special-shaped hollow steel pipe with inner groovy at the center of mini pile stake holes, is poured in special-shaped hollow steel pipe
There is cement concrete in pipe, reinforcement is plugged with the inner groovy of special-shaped hollow steel pipe, in special-shaped hollow steel pipe and mini pile
Locating support is provided between stake holes inwall and pile body cement concrete has been poured.
The mini pile antiskid structure of above-mentioned addition carbon fibre material is that described reinforcement is reinforcing bar or carbon fibre bar
A kind of or both combination.
The mini pile antiskid structure of foregoing addition carbon fibre material is that the inner groovy in special-shaped hollow steel pipe is
It is distributed on the semi arch of indent on body.
The mini pile antiskid structure of foregoing addition carbon fibre material is that asphalt mixtures modified by epoxy resin is scribbled between inner groovy and reinforcement
Fat binding agent.
The mini pile antiskid structure of foregoing addition carbon fibre material is to be surrounded by carbon outside special-shaped hollow steel pipe and reinforcement
Fiber cloth, scribbles epoxy resin on the inside of carbon cloth.
The beneficial effects of the utility model are：
（1）The mini pile antiskid structure of the addition carbon fibre material plays antiskid key in stratum is slided, and effectively increases
The shearing strength and resistant slide, non-deformability of strong slope soil, and construction is simple, short time limit, cost is low, flexible arrangement, and
Anti-slippery effect is good.
（2）The mini pile antiskid structure of the addition carbon fibre material is compared to general material friction pile, with carbon fibre bar
Instead of all or part of reinforcing bar, the ultimate resistance strength of mini pile antiskid structure, bending strength and tension bearing capacity are significantly enhanced.
（3）The special-shaped hollow steel pipe is provided with identical size and equidistant three arc concave shape structures, carbon fibre bar
Insertion can combine closely after scribbling the concave inward structure of epoxy resin with steel pipe, improve the whole of stake core carbon fiber-steel pipe combination component
Body stress uniformity, and solve the connectivity problem of steel pipe and carbon fibre bar.
（4）The carbon cloth of the stake cored structure outsourcing, can by smearing epoxy resin tight bond to stake cored structure
Improve the anti-shear ability of stake cored structure and strengthen its stress uniformity, improve service life.

Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Reference picture 1, the application, which is laid in before slip slope surface, component, need to slide stratum and stably before laying
Mini pile stake holes on layer（1）, in mini pile stake holes（1）After opening up, in mini pile stake holes（1）Center be put into and be enclosed with carbon
The carbon fiber of fiber cloth 4-steel pipe combination component.The center of the described carbon fiber for being enclosed with carbon cloth 4-steel pipe combination component
Body is band inner groovy（9）Special-shaped hollow steel pipe（6）, described special-shaped hollow steel pipe 6 is equidistantly to be distributed with three on steel pipe
Individual arc concave shape groove 9 is formed, and described inner groovy is semi arch, epoxy resin is scribbled in inner groovy 9, pipe is then in inner groovy
Reinforcement 5, described reinforcement are completely or partially inserted in 9（5）For a kind of or both combination of reinforcing bar or carbon fibre bar,
Reinforcement is set to combine closely to form carbon fiber-steel pipe combination with special-shaped hollow steel pipe 6 by the build-in of epoxy resin and inner groovy 9
Component.Carbon fiber-steel pipe is fitted tightly over after flexible carbon cloth 4 smears epoxy resin, then by flexible carbon cloth 4
