In the flowing China, the EMU trains are like "steel dragons" speeding on the railway lines. In order to ensure the safe arrival of the train, many railway youths fought the cold, ensured safety, resisted ice and snow, and ensured smooth traffic, practiced the fundamental purpose of "people's railway for the people" with actions, took root in the scene, monitored the key, adhered to the foolproof bottom line, and wrote heart-warming stories one after another, interpreting the heavy responsibility and guarding the passengers' safe way home.
During the Spring Festival, the railway communication department strengthened the monitoring and control of trackside equipment to ensure the normal operation of communication trackside equipment.
Rail "grinder".
No. 1 slot is there! Enter mode 51, and the swing angle of each grinding head is in the correct position! He Bin, who was sitting in the main operation position, used the walkie-talkie and Pu Qiye to confirm the grinding operation mode, and at the same time observed the operation of the grinding equipment on the operation screen.
Go under the knife! Start grinding! Pu Qiye gave a grinding order, He Bin slowly pushed the handle, dropped the grinding wheel, and the knife instantly "stabbed", and sparks burst out from between the grinding wheel and the rail.
In the early morning of January 26, at Suzhou North Station of the Beijing-Shanghai High-speed Railway, the sound of the machine rumbled and the figure shook.
The Beijing-Shanghai high-speed railway is one of the busiest transport trunk lines in the country, and it is also a national railway standard demonstration line. At the beginning of the Spring Festival, Shanghai Depot organized the grinding workshop and five work classes to sign a safety commitment, organized the technical backbone of the team to set up a youth commando, and used the intermittent period of the night high-speed rail suspension to polish and repair the rail, restore the rail contour size, make the wheels and rails form a reasonable contact surface, and ensure the speed and stability of the train.
Rail "grinder".
Rail "grinder".
Rail grinding can not tolerate a little sloppy, grinding shallow can not remove the root of the disease, too deep and will affect the life of the rail, must ensure that the rail contour error after grinding is less than 02 mm, which is equivalent to the thickness of 2 sheets of A4 paper, so that the high-speed rail can run more smoothly and safely. “
Previously, there was a hot search on the Internet**: On the high-speed railway with a speed of more than 300 kilometers per hour, the coin is placed vertically, which can smoothly maintain the state of the coin not falling. "Here's where we go! Pu Qiye's face was full of pride.
4 a.m., 9 a.m4 km of rail grinding is completed. The "grinders" who got out of the car had already attached a layer of black dust to their original white masks, and their work clothes were also covered with black stains. During the Spring Festival, Pu Qiye will lead the rail "grinder" to run along the Yangtze River Delta Railway every day, polishing rail diseases, working overtime day and night, and guarding the safe travel of passengers.
Air "medical team".
In order to ensure the return of the Spring Festival and the opening of the school one after another, the Xi'an Electrification Branch of China Railway Electrification Bureau, a joint participating unit of the Nanjing Power Supply Section, organized 58 technical backbones to set up a youth commando team, with an average age of 25 years old, to be responsible for all-round diagnosis of the catenary equipment of the new Chihuang High-speed Railway Taipinghu Bridge.
Put on the headlamp, fasten the seat belt, climb to the top of the ladder access platform, turn out the tightening wrench from the tool kit, and tighten the parts on the catenary in turn. At 1:38 a.m. on January 31, catenary worker Jiang Wei and his colleagues were rectifying the shortage of catenary equipment.
Under the illumination of the headlamp, the dark surface of Taiping Lake is bottomless, and the sound of whistling wind and metal colliding during operation comes and goes. "This hanging string is abnormally stressed, you see! The sharp-eyed Jiang Wei quickly took out the catenary laser measuring instrument to measure, "the height difference between the adjacent hanging strings is 12mm, which exceeds the standard value." The hanging chord is the connecting part between the load-bearing cable and the contact line in the catenary chain suspension, and the length of the hanging chord is adjusted to maintain a certain height of the contact wire from the rail surface to improve the quality of the current.
Jiang Wei and the team members used the catenary laser measuring instrument to check the height of the hanging string one by one. "There are still 40 minutes left, the order is lifted, hurry up! Jiang Wei's walkie-talkie came with a command. At this time, the cold wind made people shake all the time, and the team members were panting, but the movements of their hands did not slow down in the slightest. At 3:40 a.m., the assignment ended. The commandos packed up their tools and headed for the Yellow Hole Tunnel ahead.
The Chihuang high-speed railway connects Chizhou City and Huangshan City in Anhui Province, and also connects well-known scenic spots such as Jiuhua Mountain, Huangshan Mountain and Taiping Lake, and is the most representative tourist line in Anhui Province. In the first half of this year, it will "Helong" with high-speed railways such as Ning'an and Changjinghuang to open up the last kilometer of the "** line" in New Anhui and Jiangxi.
Catenary workers debug equipment at the construction site of Chihuang high-speed railway.
Catenary workers debug equipment at the construction site of Chihuang high-speed railway.
Previously, Jiang Wei had participated in the construction of high-speed railways such as Changjinghuang, but in contrast, the humid environment and changeable climate at the construction site of the Chihuang high-speed railway brought more resistance to the construction. This section of the line is about 125 kilometers long, with 55 bridges and 34 tunnels, and bridges and tunnels account for 88%, which is one of the sections with the most mountains and forests and the most dense lakes in southern Anhui.
On the eve of the Spring Festival, the Chihuang high-speed railway entered the stage of joint commissioning and joint test, and the countdown to opening and operation began. This year's Spring Festival, this group of catenary workers is even busier, twisting wrenches, replacing parts, adjusting parameters, and measuring data. On average, six of these "skylight" jobs are completed per week. "When the spring flowers bloom, passengers can take this '** line' to enjoy the beautiful scenery of Anhui, and when the time comes, I can also have a good rest. Jiang Wei said.
Tunnel "Mountain Chaser".
At 22:30 on February 4, You Xiaobo, Di Yipeng, and Wang Yinzheng, under the leadership of foreman Yu Jibin, arrived at the col at the north end of the Bailuoshan Tunnel. At this moment, the temperature is approaching 0, the drizzle is continuous, and the cold wind is biting. Walking to a railway bridge, they took their kits and walked down the steps towards the passage door, which looked like they were "flying on the wall" from a distance.
They are the communication workers of the Shanghai communication section. During the Spring Festival, You Xiaobo, Di Yipeng, and Wang Yinzheng, three "post-00s", took the initiative to sign up for the youth commando, and solemnly wrote down the promise of "ensuring the safety of trains and passengers".
The Bailuoshan Tunnel is the longest tunnel along the Hangzhou-Shaoxing-Taizhou Railway, with a total length of 10,006 meters, more than 40 tunnel emergency departments, and multiple communication repeater rooms. They need to complete the maintenance of 4 repeater machine rooms and 20 tunnel emergency dial tests during the "skylight" time, and at the same time, they also need to check the damage, bending and suspension of 4 leaky cables at an average speed of 50-100 meters per minute, and maintain the loosening and falling off of the buckles, which has extremely high requirements for efficiency.
In order to ensure smooth communication between trains and stations, trains and trains, this group of "post-00s" has become mountain drivers, busy in the mountains and mountains every day.
At 0:00 a.m., the cold wind blew on the face and stinged exceptionally, and they arrived at the first computer room in the direction of the leaky cable. Di Yipeng used a multimeter to test the output voltage of the battery and UPS, Wang Yinzheng recorded on the side, You Xiaobo cleaned the dust of the equipment, checked the fire extinguisher, and tested the performance of the equipment, and the three of them cooperated in an orderly manner.
Emergency ** is an important contact tool in the event of an emergency in the tunnel, in order to ensure good performance, Di Yipeng needs to use the tunnel emergency ** and the "dispatching command center" and the station to conduct a call test during the "skylight" time, to determine that the equipment is in good condition and record the test results, it is necessary to rush to the next work point, such a test needs to be repeated 20 times in different caverns.
The tunnel light is not good, and when walking on the cover plate on both sides of the road, some of the cover plates are damaged and loose, so you should be very careful. At the job site, they almost walked and checked, raising their heads in three steps and bowing their heads in five steps, and twisted them by hand when they encountered the missing cable buckle. After a five-kilometer inspection in one night, the noses of the three people were red from the cold, a layer of water beads had accumulated on their hair, and they became sluggish when they bent over and got up.
After work, they also have a "post-00" side and like to communicate with their families. Yu Jibin, the foreman, said that they are all young people who live in other places and have to stay in the work area for almost half of the year. "At the busiest time of the year, it is also because of the perseverance of this group of 'post-00s' to move forward, work 'continuous rotation', stick to their posts and guard the normal operation of equipment, so as to ensure the safe and orderly operation of each train, so that every passenger can arrive safely and smoothly. ”
