Railway flood attack test experts say the cost limit across the board high standard of flood control

Early on the night of July 25 to 26, torrential rains in the Midwest of Inner Mongolia, Hohhot railway administration caused by jurisdiction within the scope of the main package railroads, from Inner Mongolia into Beijing passenger bus almost all blocked, total of 24 times, a total of more than ten thousand passengers stranded. On July 26, Beijing to baotou K263 times, to the northwest of Beijing dongsheng K573 inferior trains many times.

In the recent round of heavy rainfall to railway flood control and final exam. Held on July 23 TV conference call national railway transportation, the ministry of railways for the railway administration efforts to do a good job of flood control and safety, especially to strengthen inspections after the rain, well water disasters area reinforcement reinforcement work, avoid secondary disasters.

Beijing package such as interrupt lines opened again

Beijing railway line after the interruption, Hohhot railway bureau immediately start emergency preplans for flood control and has blocked its camp - three battalion, three - line between ethnic groups, to ensure the security of the passenger train. At the same time, the railway department and the local garrison organization rescue overnight. Stuck in order to appease the stranded passengers, railway departments to train passenger number, whereabouts, and train meal, flood control material in parts, to ensure that all kinds of food material is enough, mineral water and drinking water can meet the demand of passengers, at the same time turn-back, evacuating passenger railway station in time to deal with the blocked all 12000 passengers got on the train. Railway department to refund the full fare ticket to shut down the train at the same time, many travelers to explain and apologize.

26, the railway department and the local garrison more than ten hours to repair, because of the heavy rain interrupted package of Beijing railway JiNing to Hohhot segment line across the opening, recovery.

It is understood that the current flood cause the main reason is that the subgrade of railway lines, followed by Bridges, culverts. Related statistics, about 80% of the water disasters occurred in subgrade and lines, remove the line height less than easy to flood inundated and scouring of the local area, the subgrade water damage is more due to the imperfect and protection engineering slope unstability, vulnerable to torrential rain induced by a variety of geological disaster, including landslides, mud-rock flow, roadbed subsidence and so on.

Railway flood control "more on human"

A railway engineer in the daily economic news (weibo) told reporters, railway design will give full consideration to the problem of flood control, if they are ordinary railway, the subgrade design of circuit requires good drainage, drainage was not up to standard, if want to make the waterproof layer, dug sewers, on both sides of the wall and so on, if it is a high-speed rail viaduct, is under the viaduct reinforcement installation facilities. "But now I fear most is a railway cast time limit for a project, or cut corners, this also is the big fear of railway flood control." According to the engineer, the railway flood control standards if increased by 40% ~ 50%, may have to spend billions of engineering cost, with the implementation of a high standard of flood control across the board. "The point of railway flood control is to do the investigation, according to the geological structure of different regions, in a key location design flood control standards, but natural disasters is inevitable."

21, Beijing 61 strong rainfall, the worst result in Beijing railway administration at 04:38 jingguang, feng bearing sand, Beijing, Beijing, Beijing, tianjin, rebar, west long 7 main section or blockade, more than the original line of Beijing landslide buried lines. Beijing railway administration organization of railway worker, troops and those employees thousands of people day and night to repair. 19 to 23, Beijing railway administration at 04:38 lines all opened, returned to normal transport order.

The railway engineer, railway flood early warning and emergency rescue more by manpower, "washed out thrust general rail, rail line on the machinery room will automatically alarm, washed out is not easy, but the rail is often railway embankment burst or railway water, but the mechanical room there will be no alarm, then can only rely on manpower to check." He introduces, in tangshan region, for example, if the hourly rainfall reached more than 10 mm, railway workers on the road overhaul; If it reached 35 mm to the train speed limit notice; If there is a danger, more than 100 mm or will directly will stop the train stopped.

It is understood that the railways have rainfall observation points along railway lines. The ministry asked all relevant departments to strictly enforce rainfall warning system, strengthen the machine from spreading and spreading machine, to strengthen the dynamic inspection equipment, obsession, to ensure safety. The railway engineer said: "railway flood control is a systematic and complicated project, need the railway careful organization and coordination with the up and down."
