Jinan's first subway yesterday formally entered the track laying stage On the morning of August 20, workers laid a 25-meter rail to the viaduct deck line at the base station of Chi Dong, the starting station of R1 line. At 9:16 on the 20th, Ji'nan Metro R1 line departure station Chi East laying base, the staff operating a gantry crane, a 25-meter track will be smooth pavement to the viaduct line. Rail and U-beam "first intimate contact", but also marks the first subway in Jinan formally entered the track laying stage, the focus of construction projects will also be gradually shifted from civil construction machinery and electrical equipment installation and other major processes. Spring Metro people long-awaited Metro Dream, from reality is a step closer. The first section of rail station settled East Station using "rail laying method" pave the way for the subway Early on the morning of the 20th, the starting line of the eastbound station of Chi-Chi Station in R1 line was ready. Two long gantries were ready and a long track was placed under the gantry. Under everyone's attention, the higher and higher rails, closer and closer to the U-beam. China Railway Bureau operations team captain Yuan Fang introduced Jinan elevated section of the first subway is the "rail alignment method." In other words, in the laying of the base in advance 25 meters long rails, sleepers, fasteners, etc. assembled into the rail after hanging in place to form a track bed as a whole. Finally, the use of mobile flash welding welding machine, the scene will be welded into a seamless rail line, to achieve rail. Designed a total of three laying base in April next year to achieve long-track overhead elevated On the viaduct, under the command of the "semaphore" of construction workers, the rail line rising up steadily falls on the bottom of the elevated U-beam. After making precise "alignment" adjustments, more workers started installing connectors. R1 Railway Line Deputy Project Manager Dong Yanpeng introduced a 25-meter-long section of each pavement about 75 meters -100 meters every day, that is, there are 3-4 day-to-day rail will be on the bridge. In the R1 line, a total of 3 laying track base, respectively, Chi Dong laying track base, Yuronghe track laying base and Yan Mazhuang shop base. Because the earliest pavement base pool laying conditions, so the first section of the track here to shop. Chi East laying track base will be responsible for the starting point to the University City Station Station, 3 stations 4 double line total of about 7.2 km. Yurong River laying base from September 2017 began laying track. The whole elevated section is expected to achieve short-track in December 2017 and is expected to achieve long-track traffic in April 2018. Every 5 meters there is a pair of "eyes" monitoring to ensure accurate orbit alignment When the subway runs at high speed, the smoothness of the track determines the safety and comfort. On the beam side of the elevated U-beam, the reporter found that there is a hole below the letters and numbers are also marked. Dong Yanpeng told reporters that such a hole every 5 meters there is one, belonging to the CPIII control network technology "eyes", "smart focus" after the fine adjustment of the track laying. This technology, you can ensure that the track straight straight, smooth curve, smooth transition. Reporter was informed that these are "paving" rails for the Jinan Metro rail steel from Panzhihua Iron and Steel Plant, is the highest level of domestic steel, resistance (such as performance is first class. 360-degree dead-end monitoring mobile phone can see real-time construction site More than cloth fine tuning technology in line with the Jinan "smart subway" position, in order to improve the construction safety and construction efficiency, construction side also things technology, intelligent hardware technology used in the laying process. In Dong Yanpeng's cell phone, the reporter saw an app that reads Jinan subway software. Construction site attendants attendance and real-time location monitoring, construction status, construction progress, the distribution of construction personnel, the future operation of the train, etc., can be dispatched through the command center or authorized managers to view real-time mobile phone. In addition, R1 underground segment is "hole pass" sprint, track laying is expected to begin before the end of this year, plans to achieve full line before the end of next year. By 2019 to achieve "electricity", that is, the subway flying to us from the time.
