Abstract
Along with the fast development of building trade, more and more pile foundations are used in building engineering. The condition such as broken pile or pile body destruction appear in this basis easily when earthquake and pile. Consequently the development need of pile foundation is continuous perfect. The utility model relates to a be a prefabricated steel -pipe pile of inside reinforcing. The steel -pipe pile is inside to have tangent interior hunch, has built the concrete between interior hunch and the steel pipe, and the stake receives in earthquake process on the ground pressure reaches inside concrete and tangent interior hunch by the steel pipe, pushes mutually between the interior hunch, produce counter -force counteract steel pipe on, can provide effectual inside holding power for the steel pipe, prevent that it breaks crowd bad pressure at in -process pile bodies such as earthquakes by the soil pressure.
Description
Technical field
This utility model relates to the design field of stake, is a kind of internal pre-manufactured steel pile tube strengthened.
Background technology
In recent years, domestic natural disaster takes place frequently, especially earthquake, set up defences building aseismicity higher requirement, especially basement process.Under raft foundation, pile foundation, strip footing, post, the application on the basis such as only base is more and more extensive.When pile breaking phenomenon when there will be piling in the application process of pile foundation and earthquake, pile body pressurized is by situations such as vibration limitses, causes collapsing and other adverse consequencess of building.Therefore, in the Aseismic Design of pile foundation building, the process of pile strength is undoubtedly a vital link.
Summary of the invention
This utility model is the innovation not enough for prior art.
This utility model is a kind of internal pre-manufactured steel pile tube strengthened, and pile body main body is steel pipe, the interior arch that interior welds four is tangent, and interior camber piece material is also steel, together with outer steel-pipe welding.Fill concrete between interior arch and outer steel pipe, in advance fills EVA resin expanded material inside the hole formed between interior arch and interior arch.Wherein, described prefabricated steel pipe is straight weld steel pipe
This utility model has following remarkable advantage compared with conventional steel pile tube:
1. experiment shows, under conditions of soil pressure is identical with pile peripheral friction force, pressure suffered by pile body is transferred to interior arch by outer steel pipe, between interior arch and interior arch and and packing material between form extruding, arch-shaped steel plate produces the identical reaction force acts of size on outer steel pipe while bearing radial pressure.Provide effective inner support for outer steel pipe, substantially increase integral rigidity and the resistance capacity to deformation of steel pipe.
Design the most of the present utility model, because there being the existence of interior arch, can effectively be resisted the horizontal loading that the effects such as earthquake produce, have certain impact resistance, it is possible to significantly improve pile body stability.
3. in, filling-foam material EVA resin between arch, can effectively reduce the consumption of concrete, alleviates pile quality while ensureing rigidity.
4. the concrete filled between steel pipe and interior arch can effectively provide the comprcssive strength of pipe shaft.When being possible to prevent impact load die-cut or suffer other loads, pile body is deformed.
In sum, this utility model can effectively reduce concrete amount, alleviates pile body weight.Pile body stiffness can be effectively increased simultaneously, there is the advantages such as pile strength is high, crushing resistance is good, stability in the large is good, impact flexibility is strong, engineer applied has higher value.

Fig. 2 is elevation of the present utility model
Detailed description of the invention:
For enabling function of the present utility model and design more clearly to express, it is further elaborated below in conjunction with detailed description of the invention.
Seeing Fig. 1, pile body main body of the present utility model is made up of 2 outer steel pipes, 3 concrete, 4 interior arcuate steel plates, 1 internal foaming elastoplasticity implant.
1, by Mold Making round steel pipe 2 and interior arch 4, its China and foreign countries' steel pipe 2 welds together with interior arcuate steel plate 4, and the most tangent at seam crossing between interior arcuate steel plate 4.
2, after pile body main body is transported to building site, pile body is upright, and between outer steel pipe 2 and arch-shaped steel plate 4, casting concrete 3 carries out maintenance, carries out the 3rd step after reaching predetermined strength.
3, carrying out the foaming of elastic-plastic material in hollow between interior arch 4 and interior arch 4, expanded material can be the materials such as EVA resin, ensures that material is filled uniformly in foaming process.
4, after above end-of-job, pile crown is closed, squeezes into ground by piling machine.
Claims (5)
1. the internal pre-manufactured steel pile tube strengthened, is characterized in that arch-shaped steel plate is tangent and is tangential on commissure in internal existence, described tangent interior arch-shaped steel plate again with outer steel-pipe welding, be filled with inside stake the elastoplasticity implant formed that foams between interior arch and interior arch.
A kind of internal pre-manufactured steel pile tube strengthened the most according to claim 1, it is characterised in that by being welded to connect between described interior arch-shaped steel plate.
