Beam, huge dam, complicated subway system continue to bring out, and meet people's lives demand, while also developing into social strength
Symbol.It is the safety of engineering that civil engineering, which needs the root problem solved, and structure is enable to resist various natural or artificial works
Firmly.
Built pile is to be inserted into prestressed-concrete pile in mixing pile and formed, and is mentioned including the big specific surface area of inner body
Upper load is undertaken using internal high-intensitive concrete-pile core for frictional resistance, while again, this has high vertical bearing capacity,
And low cost.
In high-speed railway civil engineering, in the bad section of the geology such as decayed rock, Frozen-thawed cycled damages pile foundation,
The appearance repeatedly of Frozen-thawed cycled, causes the serious destruction of architectural construction, and Frozen-thawed cycled can cause serious inside architectural construction
Weathering loses durability.Existing high-speed rail stake is limited by bearing capacity, settling amount, paramos area service life compared with
Short, maintenance, maintenance cost are high.
Summary of the invention
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed
Reason, civil engineering built pile easy to use.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes soil horizon, stub, long stake, bed course
And armoured concrete slab；Several stubs and several long stakes, stub and long stake interlaced arrangement are inserted in the soil horizon；It is described
Several stubs, several long stakes and soil horizon upper surface be equipped with bed course, the upper surface of bed course has poured armored concrete
Plate；The stub and long stake are made of several main reinforcements, spiral bar, reinforcing rib, retaining wall, pile cover, concrete；The spiral shell
The outer wall of rotation muscle is welded with several main reinforcements of circumference uniform distribution, is welded with reinforcing rib between main reinforcement, the periphery of several main reinforcements is set
It is equipped with retaining wall, has poured concrete in retaining wall, pours the stake of concrete in the upper end of several main reinforcements, spiral bar and retaining wall
Cap.
Preferably, the length of the length stake is at least twice of stub.
Preferably, the bed course is coarse sand and natural soft-clay.
Preferably, the diameter of the main reinforcement and reinforcing rib is 14 ~ 20mm of φ, the diameter of spiral bar is φ 8mm.
Preferably, the bed course with a thickness of be greater than 150mm.
The working principle of the utility model are as follows: the stub of interlaced arrangement and long stake, and cooperate bed course and armoured concrete slab,
The water stability and frost heaving resistant ability of lower soil, and diffusible load are improved, to reduce the deformation of soil horizon, while playing raising
Bearing capacity, the effect for reducing settling amount and combining closely with soil layer；Spiral bar improves the compression strength of concrete, prevents from mixing
Local failure occurs under the action of tension stress for solidifying soil, improves the service life of stub and long stake.
After adopting the above structure, the utility model is the beneficial effects are as follows: civil engineering described in the utility model is used
Built pile, freezing tolerance is strong, reduces destruction of the Frozen-thawed cycled to pile foundation and stake, and the high-speed rail stake for adapting to paramos area uses, and makes
It is long with the service life, maintenance, repair cost is reduced, the utility model has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the structure chart of the utility model stub or long stake；
Fig. 3 is the top view of Fig. 2.
Description of symbols:
Soil horizon 1, stub 2, long stake 3, bed course 4, armoured concrete slab 5, main reinforcement 6, spiral bar 7, reinforcing rib 8, retaining wall 9,
Pile cover 10, concrete 11.
Specific embodiment
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Referring to such as Fig. 1 --- shown in Fig. 3, present embodiment adopts the following technical scheme that it includes soil horizon 1, short
Stake 2, long stake 3, bed course 4 and armoured concrete slab 5；Several stubs 2 and several long stakes 3, stub are inserted in the soil horizon 1
