Description
Technical field
The utility model belongs to the protection from the wind of strong wind atmosphere Train safe operation, is specifically related to a kind of windbreak being particularly useful for electric railway under the strong wind atmosphere of the security protection of train in electric railway under strong wind atmosphere and pantograph and contact net.
Background technology
The South Sinkiang of China and the railway line part of the Northwest are positioned at that strong wind is frequent, the powerful region of wind-force, and maximum instantaneous power can reach 64m/s, and train operating safety has been arrived in serious threat, also the accident that train is turned in large wind once repeatedly occurs.For solving the problem of the large wind effect traffic safety of the strong wind train line such as Lan-xing Railway Bai Lifeng district, China has carried out lot of experiments research, and built windbreak according to result of study, under determining different wind speed, the wind speed scale of dissimilar train running speed limit value and stoppage in transit.
Since 1970, Lanzhou Desert Inst., Chinese Academy of Sciences and surveying and designing institute of the Ministry of Railways and section all departments, combine to train topple ambient conditions, harm is formed and Critical vehicle turnover wind speed has carried out investigation, observation and indoor and outdoor experimental study.And propose the design height of the body of wall that keeps out the wind, for the design of single-wire line windbreak and construction provide foundation, successively build many places windbreak engineering at strong wind location embankment windward side.Between 1987 ~ 1993 years, Urumqi Railway Bureau is for improving Xinjiang strong wind district railway wind loading rating, ensure railway operation safety, with Peking University, china academy of railway sciences, Ministry of Aerospace Industry's aerodynamic studies cooperated, according to aerodynamic principle, adopt the research method of wind comfort, on-the-spot Train experiment, to strong wind Disaster cause, anti-Wind Engineering Rational structure, effective protective range and overturning wind speed and improve train crosswind sensitivity aspect, carried out the research of some basic aspects.Since 2003, applicant in this case Central South University has carried out the research of extreme crosswind Train aerodynamic characteristic, train overturn stability Journal of Sex Research, the windproof study mechanism of windbreak, the Reasonable Shape of windbreak and reasonable altitudes research under different road conditions (comprising level land, bridge and embankment).
Foreign railway traffic developed country all pays special attention to this.For example Japan, owing to being the island country of monsoon more than, the accident causing derail to be toppled because of strong wind happens occasionally, to train high embankment, viaduct run time large wind effect problem, conduct in-depth research respectively, grasp its rule and determine the measure of dealing with problems; The country such as English, moral, method, Italy, Sweden in West Europe have also been made extensive work.All these countries are substantially identical by the thinking researching and solving problem, comprise determine under different wind speed, the wind speed scale of dissimilar train running speed limit value and stoppage in transit, build windbreak, set up strong wind area monitoring system etc.
But research both at home and abroad all only for the protection of train, and does not relate to the impact of windbreak on pantograph and contact net.At present, Trains on Nanjiang Line and Lan Xin line mainly have employed earth embankment formula, reinforcement to pull-type, concrete is board-like and the windbreak of the concrete pillow type such as direct insertion.But, the windbreak of several form above, the situation that original railway line adopts diesel locomotive is only have been directed to when designing, namely a consideration windbreak is to the protection of train, and do not consider that windbreak is on the protection of pantograph and contact net and impact, particularly earth embankment formula windbreak, or the windbreak on embankment, can have a negative impact to pantograph and contact net.Now there are some researches show, after the air-flow of strong wind crosses windbreak, can accelerate above roof, thus make aerodynamic force larger suffered by pantograph and contact net, and then bow net contact stability is had a negative impact.Simultaneously existing windbreak build long in time limit, the higher problem that simultaneously also can cause subgrade settlement because of wall weight of cost.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of can the protection body of effective sand-proof, reduce building costs, improve efficiency of construction, and the windbreak of electric railway under playing the strong wind atmosphere of the effect of effectively protecting train, pantograph and contact net.
The purpose of this utility model is achieved by following technical proposals:
Described windbreak comprises basis and body of wall, and body of wall is positioned on basis, is continuous integral structure;
The leeward side of described windbreak, towards rail vehicle, is arranged in the one or both sides of electrified railway track; Its top exceeds the top 100-200 centimetre of rail vehicle;
The windward side of described body of wall arranges gusset, forms air channel between adjacent two gussets, the width in air channel is not more than 150 centimetres.
Described windward side is for being in tilted layout, that is: the acute angle that the extended line of windward side and ground line are formed is 70-85 degree.
The combination of described windward side curved or straight line and camber line in vertical cross-section.
Described gusset is for being in tilted layout.
Described gusset is that broken line form is arranged.
Described gusset is that the arc of arc or the positive and negative shape of multistage is arranged.
Compared with prior art, the utility model has the following advantages: simple structure is reasonable, building costs can be reduced, improve efficiency of construction, play the effect of effectively protecting train, pantograph and contact net, also significantly can improve train top flow field characteristic simultaneously, reduce the lateral force suffered by car body and lift.
