Abstract
The utility model discloses a kind of sawtooth anchor formula miniature steel pipe concrete-pile for slope treatment.Including sawtooth anchor formula miniature steel pipe pile（4）, sawtooth anchor formula miniature steel pipe pile（4）Outer wall on along its axis direction zigzag to be distributed with raised（3）.The utility model has the characteristics of stability is good, bearing capacity is strong and simple in construction.
Description
Technical field
The utility model is related to Geotechnical Engineering slope retaining field, and particularly a kind of sawtooth anchor formula for slope treatment is micro-
Shape steel tube concrete-pile.
Background technology
Miniature steel pipe concrete-pile refers generally to a footpath less than 300mm, using drilling, arrangement of reinforcement and slip casing by pressure construction technology
Bored concrete pile, its construction is mainly made up of steel pipe socket, reinforcement, injecting cement paste and associate member, extensively should be obtained at present in slope project
With.Its construction technology process approximately as：First, data is reconnoitred according to place, drilled in the region for the processing that needs reinforcement to setting
Count depth；Then, miniature steel pipe pile is entered in drilling interpolation, the space cast toward steel pipe inner side and between steel pipe and borehole wall is mixed
Solidifying soil；Finally, steel pipe and concrete are combined to form miniature steel pipe concrete-pile, and are embedded into sliding surface certain depth below,
Play a part of reinforcement.
Although miniature steel pipe concrete-pile is widely used in slope project at present, but still lack with many
Point, such as bearing capacity of single pile are low, anchorage of pile end power deficiency, situations such as stake destruction occurs often or is pushed over so that miniature steel pipe
Concrete-pile is more as a kind of gib.Art methods are related to a kind of umbrella anchor framework-type miniature pile, the practicality
It is new to be formed by umbrella anchor skeleton and filling concrete, what umbrella anchor skeleton was set including a longitudinal mobile jib and along the longitudinal direction of mobile jib
Umbrella support.Each umbrella support includes umbrella body frame, the support frame being hinged with umbrella body frame, be socketed on mobile jib and along mobile jib slide it is outer
Sleeve pipe.Relevant position that can be in the borehole using the umbrella anchor skeleton increases the stake footpath of mini pile, and the opening direction of umbrella support upward may be used
Strengthen the upper and low approximations of mini pile, can strengthen mini pile down pushes bearing capacity, and existing reinforcing bar is replaced with the umbrella anchor skeleton
The stake that cage skeleton can shorten mini pile is long, reduces quantities, safety and reliability.Although umbrella anchor framework-type miniature pile improves stake
Bearing capacity, but due to its complex manufacturing, and site operation difficulty is big, limits its application in engineering.
The content of the invention
The purpose of this utility model is that there is provided a kind of sawtooth anchor formula miniature steel pipe concrete-pile for slope treatment.
The utility model has the characteristics of stability is good, bearing capacity is strong and simple in construction.
The technical solution of the utility model：A kind of sawtooth anchor formula miniature steel pipe concrete-pile for slope treatment, including
Zigzag projection is distributed with along its axis direction on sawtooth anchor formula miniature steel pipe pile, the outer wall of sawtooth anchor formula miniature steel pipe pile.
It is previously described in the sawtooth anchor formula miniature steel pipe concrete-pile of slope treatment, described sawtooth anchor formula miniature steel pipe
Reinforcement is additionally provided with the inner cylinder of stake.
It is previously described in the sawtooth anchor formula miniature steel pipe concrete-pile of slope treatment, described zigzag is raised to described
Sawtooth anchor formula miniature steel pipe pile on the outside of development length L be stake footpath D 1/4~1/3.
It is previously described in the sawtooth anchor formula miniature steel pipe concrete-pile of slope treatment, described reinforcement is I-steel.
Beneficial effect
Compared with prior art, the utility model is on the basis of traditional mini pile, in steel pipe socket (sawtooth anchor formula miniature steel
Pile tube) to be evenly arranged jagged zigzag raised in outside, and by the simple structure, a footpath locally not only is being added, is being increased
The module of anti-bending section of stake, enhances the anti-bending bearing capacity of stake, upper and low approximations and pushes bearing capacity, and due to zigzag
The presence of the effects such as raised and stake surrounding concrete snap-in force, enhances the resistance to overturning and anchorage of pile end power of stake.This practicality
It is new that reinforcement also is set in the inner cylinder of sawtooth anchor formula miniature steel pipe pile, effect of contraction can be played to pile concrete, work as steel
When pipe concrete pile is by curved load, bending resistance can be played a part of；Moreover, reinforcement of the present utility model is I-steel knot
Structure, because its edge of a wing is wide, lateral rigidity is big, and unbending can be played by further improving, and then improve the resistance to overturning of component.
In addition, a kind of sawtooth anchor formula miniature steel pipe concrete-pile for slope treatment involved by the utility model is easy to produce and applied
Work, can be widely applied in engineering.Applicant is in practice, it has been found that when the raised development length L of zigzag is excessive, be then difficult to
Construction, its too small supporting effect is again undesirable, and after a large amount of practice summaries, applicant draws, when development length L is stake footpath D
1/4~1/3 when, its difficulty of construction and supporting effect are optimal.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state schematic diagram of the present utility model.
Mark in accompanying drawing for：1- reinforcements, 2- drillings, 3- zigzags are raised, 4- sawtooth anchor formula miniature steel pipe piles, 5- cores
Heart concrete, 6- side slope soil layers.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment 1.A kind of sawtooth anchor formula miniature steel pipe concrete-pile for slope treatment, is constituted as shown in Figure 1-2, bag
Include on sawtooth anchor formula miniature steel pipe pile 4, the outer wall of sawtooth anchor formula miniature steel pipe pile 4 that zigzag is distributed with along its axis direction is raised
3。
Reinforcement 1 is additionally provided with the inner cylinder of foregoing sawtooth anchor formula miniature steel pipe pile 4.
Foregoing zigzag projection 3 to the development length L in the outside of described sawtooth anchor formula miniature steel pipe pile 4 be stake footpath D's
1/4~1/3.
Foregoing reinforcement 1 is I-steel.
During construction, a drilling 2 is bored to projected depth in the need reinforcement region of processing of side slope soil layer 6, in pore forming process
It should ensure that bottom hole sediment is cleaned out because the soil body is disturbed without caving in；It is then that sawtooth anchor formula is micro- after the completion for the treatment of pore-forming
Shape steel tube concrete-pile is put into drilling, and pile is completed under its Gravitative Loads；After the completion of pile, in sawtooth anchor formula miniature steel pipe
Gap in the inner cylinder of stake 4 and its between outer wall and the hole wall of drilling 2 pours core concrete 5, pours after core concrete 5,
Maintenance, shaping, that is, complete construction.Concrete-pile after construction can be used to the reinforcement processing of side slope.
