changsha evening news changsha news on october 5th (all media reporter peng fang correspondent yang yunzhi) late at night on the 4th, at the muyun station of the changsha-zhuzhou-tanxi intercity railway, the light from several moving headlights pierced the darkness. huang lei led the railway signal workers and rushed to the work site carrying heavy tool bags. only their footsteps could be heard in the completely silent surroundings.
huang lei, 32 years old, is the foreman of the muyun intercity signaling works area of the changsha telecommunications section intercity signaling workshop of guangzhou railway group and a member of the communist party. together with 9 workers, he guards 4 stations, 167 switch machines, 65 track sections, 61 signals and other signaling equipment.
muyun station is located at the center of the confluence of the three cities of changsha, zhuzhou and tan. it is the "throat" of the changzhou-zhuzhou-tanzhou intercity railway. it undertakes the important task of intercity railway trains traveling north, south, westbound and eastbound. it receives and departs trains every day. hundreds of pairs, sending tens of thousands of passengers every day.
huang lei told reporters that the turnout is equivalent to the steering wheel of the train, which is used for the train to change direction or make a u-turn. during the national day, train operations are intensified and the turnout frequency increases. "like the set of no. 309 turnouts i have on hand, trains from changsha to zhuzhou and xiangtan pass through it. they are operated up to 80 times a day and require frequent maintenance."
turnout maintenance is a delicate job. maintenance standards are measured in millimeters and there is no room for error. with a nightlight on his head and a feeler gauge in his hand, he bent over the rail and carefully checked the gap size of the switch rails.
"the standard gap value of the turnout is 2.0±0.5 mm, and now the gap has been adjusted to 2.0 mm." huang lei said that his job is to build standardized equipment according to standardized operating procedures, and always be true to the "millimetre".
since joining the railway in 2013, huang lei has participated in various construction and equipment renovation work of the beijing-guangzhou high-speed railway-wuhan-guangzhou section, the shanghai-kunming high-speed railway and the lou-shao high-speed railway within the changsha electric power section, and has accumulated rich on-site experience.
in 2016, huang lei, as the first batch of acceptance personnel during the construction period of the changsha-zhuzhou-tanzhou intercity railway, participated in the entire construction intervention, acceptance, joint debugging and joint testing of this railway. every set of switches, every track circuit, every signal machine has a detailed ledger in his mind.
now, as the guardian of the "throat" of the changsha-zhuzhou-xiangtan intercity railway, he can't tolerate any sand in his eyes.
during the equipment rectification before the national day, huang lei keenly discovered that the fault current of the w3 switch in muyun maintenance depot was abnormal. after careful inspection, he found that the friction belt was seriously worn, and he immediately used the skylight time the next day to solve the problem.
"high-speed rail safety is no small matter, and a slight mistake may lead to a catastrophe." after huang lei confirmed that the switch gap debugging was normal, before he could breathe a sigh of relief, he and his colleagues turned to inspecting various parts of the mechanical installation device. taking out the wrench, the two of them cooperated, sometimes squatting, sometimes lying on their stomachs, to touch every screw in the switch, making sure it was tightened in place one by one.
"only by bending down and squatting down can we carefully confirm every detail and ensure the safety of the train." huang lei needs to bend down and squat down hundreds of times to check the train after getting down from a skylight (280 minutes for a large skylight and 180 minutes for a small skylight).
"the skylight point will end in 10 minutes. people outside are preparing to exit, pay attention to safety." following the prompt from the intercom, huang lei stood up, hammered his sore waist, organized tools with everyone, and evacuated in an orderly manner.
"this year's national day holiday is about to usher in the peak return journey. we must ensure that every train runs safely and every passenger goes home safely." on the way back, the vast darkness and silence were still accompanied, and the lights on the foreheads of huang lei and his co-workers were like night. the brightest star guides them in the direction home, and also illuminates the safe way home for travelers.
