Abstract
The utility model relates to a semi-enclosed hurricane resistant corridor. In inland areas of northwest in China, in particular to Sinkiang area, hurricane is unique natural disaster with serious damage. For example, Sinkiang in China is located in inner Asian, and has remarkable continental climate as well as strong wind power in the area and frequent gale due to the influence from cold air of Siberia and southward cold air of Ural mountains. The semi-enclosed hurricane resistant corridor comprises a plurality of upright post foundations, a net rack structure and a roof material layer, wherein the plurality of upright post foundations are arranged on a roadbed body in a eudipleural way; the lower end of the net rack structure is connected with the tops of piles of the eudipleural upright post foundations; and the roof material layer is paved on the net rack structure. The semi-closed hurricane resistant corridor has superior advantages in the environment and landscape; the roof composite material can naturally light, so that the problems that the lighting of trains and the visual fatigue of travelers can be solved. In addition, the utility model has the advantages of high specific strength and specific modulus for the roof material, designability, strong integrity and high fatigue resistance in the structure, convenience in construction and high industrial and normalized degree.
Description
Technical field
The utility model belongs to the windproof technical field of means of transportation, is specifically related to a kind of semiclosed windproof corridor.
Background technology
The Xinjiang region particularly in the NORTHWEST CHINA inland, strong wind are a kind of uniquenesses and endanger very big natural calamity.With the Xinjiang of China is example, owing to be located in the innerland, Asia, continental climate is obvious, is subjected to Siberia, the Ural Mountains to go down south the influence of cold air, and wind-force is powerful in the district, and strong wind is frequent.After Siberian cold heavy air-flow enters the Junggar Basin,, gather around and amass in the north side, Tianshan Mountains because of high mountain stops, the mountain range bealock becomes the natural lane of air-flow, and the draught head of south and north Sinkiang in addition is after cold heavy air enters bealock, take the road by force and go out, down straight along the slope, flow velocity is constantly accelerated and is formed strong wind.Strong wind causes serious windburn to the area of flowing through, and particularly railway along the line, highway facilities is caused serious harm.The accident that train is turned over by big wind repeatedly takes place in Xinjiang Railway for many years, has caused great loss for the transportation production of railway.The railway disaster caused by a windstorm form of expression mainly contains big wind and turns over the damage of train, railways train operation facility, the wheel etc. of becalming greatly, and disasters such as simultaneously big wind-induced long-pending sand buries, sandstone crushing window glass also happen occasionally.
The roadbed windproof structure is to alleviate the beam wind effect under strong wind atmosphere, the operation of protection train safe engineering measure.Its role is to change the beam wind flow field structure, alleviate rollover moment and lift that car body is subjected to, thereby guarantee the safety of operating train (vehicle).Existing roadbed windproof structure is one-sided paravent, and it is influenced seriously by sand damage to the security protection deficiency of the train of running at high speed, and view is also relatively poor.
In recent years, along with the construction of China Express Railway, the improving constantly of train running speed tackled windproof engineering mutually and proposed more and more higher requirement.Studies show that under the extreme crosswind effect, train running speed is fast more, it is subjected to aerodynamic effect also big more, therefore, needs safer, the rational windproof structure system of research and development to satisfy the windproof requirement of the train (vehicle) of high-grade railway (highway).
The utility model content
The technical problem that the utility model solved provide a kind of under strong wind atmosphere train (vehicle) in the corridor with the fast state safe operation, take into account the semiclosed windproof corridor that solves sand damage, satisfies the view requirement.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked: special character of the present utility model is: comprise a plurality of upright post basics, space truss structure, roofing materials layer, a plurality of upright post basics are symmetrical set on the roadbed body, the lower end of space truss structure is connected with the stake top of a plurality of upright post basics that are symmetrical set, and the roofing materials layer is laid on the space truss structure.
Be provided with verge board between the above-mentioned adjacent upright post basic.
The windward side and the end face of above-mentioned space truss structure side are equipped with the roofing materials layer.
Compared with prior art, the utility model shows by experimental study, train (vehicle) in the operation of this semiclosed corridor high speed, still can safety traffic under the situation of wind effect outside the corridor, when guaranteeing installation security, solved the sand damage problem, environment that the utility model tool is higher and view advantage, its roofing composite material is by natural lighting, solved train daylighting and passenger's visual fatigue problem fully, and had the following advantages: roofing materials specific strength, specific modulus height; Structure can design, globality is strong; The structure fatigue performance is good; Easy construction, batch production and normalization degree height.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 be Fig. 1 right view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1,2, the utility model comprises a plurality of upright post basics 2, space truss structure 4, roofing materials layer 5, a plurality of upright post basics 2 are symmetrical set on roadbed body 1, the lower end of space truss structure 4 is connected with the upper end of a plurality of upright post basics 2 that are symmetrical set, and roofing materials layer 5 is laid on the space truss structure 4.
Be provided with verge board 3 between the adjacent upright post basic 2.
The windward side and the end face of space truss structure 4 sides are equipped with roofing materials layer 5, the sealing of corridor windward side, leeward side opening.
When the utility model is used in engineering, after 1 construction of roadbed body is finished, construction is basic in advance, upright post basic 2 adopts concrete cast-in-situ, intercolumniation verge board 3 adopts prefabricated plate, its central post pushes up the high-strength connector of pre-buried space truss structure 4, after foundation construction is finished, the construction space truss structure, rack is a steel work, and facade shape is an arch, and the bolted spherical node form connects, be welded to connect by bearing rebound and capital built-in fitting with the stake top, at last construction high-performance composite roof material 5 on space truss structure 4.
