Abstract
The utility model discloses a resistant corrugated steel pipe culvert of waiting, the culvert main part adopts the resistant corrugated steel pipe of time to make, it is fast to have construction speed, require not highly to the foundation bearing capacity, applicablely satisfy advantages such as durability in unfavorable geology such as weak soil and worker back culvert, phenomenon and a series of to train unsafe factor is subsided to the structure that can significantly reduce, can guarantee that the road bed is smooth -going, more economical rationality of engineering cost enables again, the life requirement of culvert in erosion environment improve simultaneously, satisfy the requirement of the quick construction of high -speed railway aperture footpath culvert, simultaneously can improve high -speed railway economic benefits, it is more reasonable with economic benefits to make high -speed railway construction culvert design and construction technique.
Description
Technical field
This utility model relates to a kind of weather-proof Performance Test of Corrugated Steel Culvert, belongs to construction of railways technical field.
Background technology
Development along with railway construction in China, metal bellows culvert received the accreditation of society people in the industry in recent years as a kind of novel culvert, China have employed metal bellows culvert at Qinghai-Tibet Highway and Qinghai-Tibet Railway in Permafrost test section and studied as pilot project, compare with traditional concrete rigid cross section culvert, wavy metal culvert is as a kind of flexible pipe, there is simple in construction, assembled convenient transportation, construction quality is easily-controllable, speed of application is fast, stone material is required few, foundation bearing capacity is less demanding, it is applicable to the advantages such as unfavorable geology such as weak soil, can to accelerating construction of railways progress, have certain effect for reducing construction investment, but for the engineering that life requirement is high, metal bellows culvert shortcoming apt to rot is then it cannot be guaranteed that the useful life of engineering, require study improvement.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is in that to provide a kind of weather-proof Performance Test of Corrugated Steel Culvert, reduces structure sediment and a series of unsafe factor.
In order to realize above-mentioned target, this utility model adopts the following technical scheme that:
A kind of weather-proof Performance Test of Corrugated Steel Culvert, culvert main body is made up by the mode lifted of weathering steel corrugated tube thick for 6mm, and wave height is 70mm, and the pitch of waves is 140mm.
Preferably, aforementioned weathering steel corrugated tube is prepared by segmentation entirety rolling mill practice.
It is highly preferred that aforementioned adjacent two sections of weathering steel corrugated tubes are connected by ring flange, ring flange is also lined with rubber blanket.
More preferably, the import and export of culvert, for all to cut head dummy, are cut head and are adopted identical slope ratio with roadbed side slope, and such structural design is prone to draining, and it is stable not affect roadbed side slope.
It is further preferred that landfill has compactness to reach the sand material of more than 90% at the bottom of culvert 0.5 times of ripple caliber depth bounds.
Additionally, be backfilled with sand horsestone in the ripple caliber width range of 0.5 times, culvert both sides.
Finally, aforementioned sand horsestone bankets to design elevation of subgrade.
Of the present utility model have the beneficial effect that weather-proof Performance Test of Corrugated Steel Culvert main body of the present utility model adopts wall is thin, rigidity is big weathering steel corrugated tube to make, have that speed of application is fast, ground requirement for bearing capacity is not high, be applicable to the unfavorable geologies such as weak soil and work after culvert meet the advantages such as durability, structure sediment phenomenon can be greatly reduced and a series of to train unsafe factor, both can guarantee that roadbed smoothed out, construction costs more economical rationality can be made again, improve culvert life requirement in erosion environment simultaneously.In railway engineering, the culvert of this kind of structure is under the premise that satisfied driving rigidity, ride comfort, comfort level etc. require, can better adapt to the differential settlement phenomenon of foundation soil, reduce culvert and settle the dangerous disease problem of train caused, it is provided that again speed of application, saves material, after reducing work, brush antirust link, reduce cost, have significant technology and economic benefit.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model done concrete introduction.
Referring to Fig. 1 to Fig. 4, the weather-proof Performance Test of Corrugated Steel Culvert of the present invention is obtained culvert main body 1 and is made up by the mode lifted of weathering steel corrugated tube thick for 6mm, and wave height is 70mm, and the pitch of waves is 140mm.Weathering steel corrugated tube is prepared by segmentation entirety rolling mill practice, and adjacent two sections of weathering steel corrugated tubes are connected by ring flange, and ring flange is also lined with rubber blanket.Owing to weathering steel corrugated culvert is a kind of erosion-resisting flexible structure, the rigidity in corrugated tube cross section is only small, can interact under load action and between the soil body, significantly provides the bearing capacity of steel pipe corrugated tube culvert and has certain shock resistance.
In order to facilitate draining and not affect the stability of roadbed side slope, the import and export of culvert, for all to cut head dummy, are cut 3 and are adopted identical slope ratio with roadbed side slope.
In at the bottom of culvert 0.5 times of ripple caliber D depth bounds, landfill has the sand material 2 that compactness reaches more than 90%；It is backfilled with sand horsestone in the ripple caliber width range of 0.5 times, culvert both sides, finally, sand horsestone bankets to design elevation of subgrade.
To sum up, weather-proof Performance Test of Corrugated Steel Culvert master of the present utility model, have that speed of application is fast, ground requirement for bearing capacity is not high, be applicable to the unfavorable geologies such as weak soil and work after culvert meet the advantages such as durability, can solve the problem that the settlement of foundation problem that the factors such as ever-frozen ground, weak soil, swelled ground, collapsible loess cause, both can guarantee that roadbed smoothed out, construction costs more economical rationality can be made again, improve culvert life requirement in erosion environment simultaneously.In railway engineering, the culvert of this kind of structure is under the premise that satisfied driving rigidity, ride comfort, comfort level etc. require, can better adapt to the differential settlement phenomenon of foundation soil, reduce culvert and settle the dangerous disease problem of train caused, it is provided that again speed of application, saves material, after reducing work, brush antirust link, reduce cost, have significant technology and economic benefit.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry, above-described embodiment does not limit this utility model in any form, and all employings are equal to the technical scheme that the mode of replacement or equivalent transformation obtains, and all fall within protection domain of the present utility model.
