Abstract
The utility model is related to a kind of corrugated steel pipe foundation structure, including the basic shell with cavity, and basic shell side is provided with the groove of placement corrugated steel pipe, and opposite side is provided with prominent step；Filler is perfused with basic shell.Corrugated steel pipe foundation structure of the present utility model practicable can improve position fixation problem during corrugated steel pipe construction, it is relatively low with high-strength light, cost, easy construction, the advantages of speed of application is fast more can guarantee that basic compactness compared to hand punning after banketing；It can be widely used in highway Performance Test of Corrugated Steel Culvert work progress, it, which is developed, and promoted will produce positive effect.
Description
Technical field
The utility model is related to a kind of foundation structure, and in particular to a kind of corrugated steel pipe foundation structure.
Background technology
With expanding economy, the infrastructure of China development like a raging fire, highway is even more big always in infrastructure
The engineering of power investment.Substantial amounts of culvert is used during construction of the highway.With the use of steel in recent years, most of culvert is all
Corrugated steel pipe is have selected to replace past reinforced concrete structure.But the position of corrugated steel pipe is fixed with basis compaction always
It is the problem of individual its popularization and application of influence.Corrugated steel pipe is in construction, by its circular cross-section should not be fixed on what is placed
Position, often occurring the position changing of the relative positions, particularly large aperture splicing structure in construction, to fix its position increasingly difficult.It is main at present
Often to be moved during construction using wooden unit or stone etc. to its simple fixation, while the wedge-shaped position machinery of bottom of the tube
It can not be compacted, artificial earth fill is difficult to ensure its density.
The content of the invention
The purpose of this utility model is to provide a kind of corrugated steel pipe foundation structure that can be used for fixing corrugated steel pipe, can be more preferably
Ensure the compactness that filler is filled.
The technical scheme that the utility model is used for：
A kind of corrugated steel pipe foundation structure, it is characterised in that：
Including basic shell, basic shell side is provided with the groove of placement corrugated steel pipe, and opposite side is provided with ledges
Rank；
Filler is perfused with basic shell.
The reserving hole channel for wearing reinforcing bar or anchor cable is reserved with basic shell.
Basic shell is docked and constituted successively by multiple stages, and docking termination is provided with neat mouth interface.
The groove surfaces of basic shell placement corrugated steel pipe are provided with the ripple being adapted with corrugated steel pipe.
Blotter is provided with below basic shell.
The utility model has advantages below：
1st, the utility model shell is made of New Geosynthetics, high-strength light, can be according to different engineerings（No
Co-wavelength, wave height and aperture）The need for be customized production.
2nd, inside the utility model it is cavity structure, can be filled out according to the different geological conditions perfusion in various regions is different
Material, can ensure the compactness of filler conscientiously.
3rd, the utility model shell is formed by connecting using each standard paragraphs for bringing all mouth, is easy to production and transportation, while often
Individual standard paragraphs are reserved can to wear the duct of reinforcing bar or anchor cable, make more firm between each standard paragraphs.
4th, the utility model has good flexible foundation, is particularly suitable for the shell structure of corrugated steel pipe, while can resist
Stronger malformation, requires relatively low to foundation quality, disclosure satisfy that unfavorable geological condition particular/special requirement.
5th, the utility model shell is using factory normalization design processing, on-site consolidation construction, and it is convenient to construct, significantly
Shorten construction period, it is easy to operate.

Embodiment
The utility model is described in detail with reference to embodiment.
A kind of corrugated steel pipe foundation structure that the utility model is related to, includes the basic shell 1 of geosynthetics, internal
It is cavity structure.The basic side of shell 1 is provided with the groove of placement corrugated steel pipe 2, and opposite side is provided with prominent step, and increase connects
Ground area, preferably prevents the movement of corrugated steel pipe 2.Filler 3 is perfused with basic shell 1, filler 3 meets local geology ring
Border, being capable of more preferable adaptive deformation with preferable flexible and bold.
The reserving hole channel 4 for wearing reinforcing bar or anchor cable is reserved with basic shell 1, while it is fixed on basic two ends, can
Increase the globality on basis, make basis more firm.
Basic shell 1 is docked successively by multiple stages to be constituted, and docking termination is provided with neat mouth interface 5.Basic shell 1 is disposed
The groove surfaces of corrugated steel pipe 2 are provided with the ripple being adapted with corrugated steel pipe 2, can be in close contact with corrugated steel pipe,
The position of corrugated steel pipe is tightly controlled.The basic lower section of shell 1 is provided with blotter 7.
The utility model includes following construction procedure：
Smooth Ground Treatment is tamped, blotter 7, and the assembled basis shell 1 on its bed course are laid, each section of connection
Get up.
Reinforcing bar or anchor cable are passed through into reserving hole channel 4, and its two ends is fixed on to the two ends of basic shell 1.Toward basis shell 1
The empty suitable filler 3 of intra-bladder instillation, and pass through vibratory equipment vibratory compaction.
The placement in layers sandy soil on the basis of, make it that its basis is completely covered, and are compacted with rolling apparatus, in corrugated steel pipe 2
The compactness of neighbouring sandy soil will reach more than 92%, the compactness more than 95% of other region sandy soil.
Corrugated steel pipe 2 or wherein assembled completion are put into basic shell 1, and basis forms good entirety.
The sandy soil of placement in layers nearby of corrugated steel pipe 2, compaction in layers, the construction until completing whole culvert.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
