More than 500 railway workers' "window period" overnight rushing workers along the river along the river to introduce Nanjing South to realize channel expansion

The air is "Spider -Man" suspended power off, and the ground is the "ants and male soldiers" of track, electrical, and signal. More than 500 railway workers in China Railway Fourth Bureau used the "window period" of the high -speed railway to rush to work overnight. It successfully introduced the construction of the south -River intercity railway signal system to Nanjing South Railway Station and was successfully locked. While laid a good basic condition for the opening of the intercity railway line as scheduled, it also allowed Nanjing South Railway Station to achieve channel expansion, forming a new pattern of "four -line" high -speed railway "Beijing -Shanghai, Ninghang, Ning'an, and South River Intercity.

Maybe to many people, the completion of a new railway line only needs to connect the rail into the station. Actually, it is far from being so simple. Railway operations are the concept of a network. A node change often means that the regional network and the entire network must be adjusted. Although the intercity railway of the south along the river is introduced from Nanjing South, it is actually equivalent to expanding the hardware to expand the hardware in the existing operating network. The introduction of signal on the evening of the 27th, as an important part of the Nanjing South Station Reform Project of the South River Intercity Railway, is a prerequisite for the future high -speed railway operation of the route. "Taking the electrical equipment of the railway as an example, only by achieving the weaker power connection can we monitor the operation of the high -speed rail in a timely manner in the future operation, and then assist other signal systems to conduct command and control." China Railway Construction Electrification Bureau Nanjing South Station Reform was restructured. The staff of the project signal group told reporters that the construction of the night required the workers to draw 248 thumb -thick signal equipment lines from the 62 electrical equipment boxes along the way, which were connected to the two railways of the two railways. Because the lines are thick and the whole process depends on manual operations, even if the work is rushing to work at high temperature and humidity, the workers are basically too busy to drink water.

Li Guifu from Anhui is 52 years old. His duty that night is to connect the weak electric signal line to the rail. The reporter noticed that because the electrical equipment box is at the outermost side of the rail, the four cables are actually led from the box to the process of crossing the two tracks from the pillow wood. The cable is heavy and tough. Not to mention, it is also necessary to insert according to the position reserved on the rail. Even if all are adjusted in place, insert the cable into the four five -corners of each rail on the rails. "It is necessary to ensure firmness, but not fixed with nuts opposite. In fact, it is hard plugged. Insert it, and the rest is knocked by the hammer head." Hammer head hurts people. The reporter was counted. According to the corresponding junction rails corresponding to each box, a total of 4 tracks and 16 empty caves were calculated in one rail. The degree of busyness is evident.

"This construction includes roadbed reinforcement, track laying, signal equipment installation, system debugging and interlocking software replacement, contact network adjustment, etc., involving 13 surrounding stations, and 2 power supply units of Nanjing South Station Hub. Li Jiliang, the head of the Nanjing South Railway Station of China Railway Construction Electrification Bureau of China Railway Construction Electricalization Bureau, said that as the main passenger station of Nanjing Hub, Nanjing South Station is divided into Beijing, Shanghai, Hangzhou, Ninghang, and Ning'an. In this car, the three busy lines of the Beijing -Shanghai high -speed rail, the Ninghang High -speed Rail, and the Ning'an high -speed rail are gathered. Through this transformation, Nanjing South Station was introduced from the south side of the Shanghai Duanxian Ning Link of Nanjing South Station in Nanjing South Station. Rongning Hangzhou and Jiangning Station Ninghangchang, forming a four -line throat.

It is not easy to complete the station reform after maintaining the operation of the railway. "Every morning from 0 to 4 am, for the daylight period of Ninghang, Nanjing South Station and Ning'an Field, we will conform to construction in seconds, deducting personnel to enter the market and exit. . "Liu Feng, head of the 4th Bureau of China Railway, introduced that in order to ensure safe construction and improve efficiency, Jiangsu Railway Group, China Railway Shanghai Bureau Nanjing Hub Project Construction Headquarters organized the China Railway Fourth Bureau, China Railway Construction Electricization Bureau and other units In full construction plan, study how to make contact network dynamic adjustments in the process of demolition and insertion of Dao forks. The signal equipment is inverted and the software is replaced. After more than 30 rounds of repeated argumentation, the weekly secret construction plan is prepared.

It is understood that in order to cooperate with this construction, the organizational force of the China Railway Shanghai Bureau Group Corporation has successively renovated and completed a number of preliminary work such as fences, roadbed reinforcement, rail pre -labing and supporting signals, and power supply equipment. Base. On the night of construction, 10 equipment management units and 300 people including Nanjing Electric Power Section, Power Supply Section, Bridge Section, Nanjing Station, Shanghai Electric Affairs Section, Communication Section, high -speed rail infrastructure section, Hangzhou Electric Power Section, and Hangzhou Electricity section participated in cooperation with construction operations Essence

The newly -built Nanfang River Intercity Railway is an important backbone line in the planning of the comprehensive three -dimensional traffic corridor of the Yangtze River Economic Belt. The design speed is 350 kilometers per hour, and the new positive line length is about 278 kilometers. As the second intercity railway between Shanghai -Nanjing, the intercity passenger flow in the passage along the line and the main cities along the line and the Shanghai -Nanjing spindle. Mingxian will be integrated into the High -speed rail circle in Shanghai and Ning.
