The construction involves 152 horizontal curves, with a minimum curve radius of 294 meters and a maximum ramp of 20.5 ‰.
In view of the typical problems existing in the safety card control, the implementation of operation standards, and the acceptance of construction quality during the previous construction, they carry out dragnet hidden danger inspection and formulate targeted rectification measures to ensure that the construction quality meets the standard at one time.
Up to now, 30.7 kilometers of track bed cleaning and 27.4 kilometers of new track replacement have been completed for Meiji line, and the construction of this line is progressing in an orderly manner.
The existing line conditions are complex and the construction organization is difficult.
Jinzhou rail changing, Shenyang rail changing and mobile rail welding workshops focus on the application of mechanical equipment, the creation of excellent construction quality and the improvement of construction efficiency.

In order to ensure that the construction period of Meihekou Tonghua Railway will be completed, our section arranges nearly 1000 cadres and workers in 8 workshops, including overhaul, rail replacement, machine screen, mobile rail welding, long rail transportation, rail car operation, and 118 special engineering vehicles such as screen cleaning machine, tamping car, rail welding car, etc., and opens 4 overhaul construction sites within 120 kilometers from Meihekou to Tonghua.
At this time, more than 150 workers in the first team of Jinzhou overhaul workshop and Jinzhou machine screen workshop were busy, and they were concentrating on mechanical screening, tamping and renovation of the main line in Gangou station.
At the same time, we will tackle key issues in the application of fast track changing vehicles and the recycling of old long rails.
In view of the diseases such as more water damaged sections of the existing line, track bed hardening and mud pumping, they investigated carefully in advance and adopted a flexible construction organization method to solve the line foundation diseases at one time.
From July 7 to August 31, it is planned to use 51 4-hour “skylights” to complete 56.306 kilometers of track bed screening and 56.301 kilometers of rail replacement.
The Party branch of each workshop extended the publicity and education classroom of the “four guarantees” to the production line, made full use of the red resources around the construction site, and carried out the activity of “telling stories of ancestors and talking about railway traditions”; Focusing on special safety rectification actions, construction safety in flood season and current work priorities, we will carry out in-depth activities such as creating posts and building areas, tackling key problems within the party, and reviewing the oath of joining the party, so as to stimulate the majority of Party members to take the lead in the “four guarantees” battle.
During the construction, Jinzhou overhaul, Shenyang overhaul and Jinzhou machine screen workshop cooperated closely and worked together.
The Meiji line construction is a large-scale construction battle with relatively concentrated personnel and machinery and complex construction organization in the second half of this year.
In view of the specific reality of railway construction in mountainous areas with many control points passing through curves and bridges and in flood seasons, they formulated a detailed construction plan, adopted the method of “wall chart operation”, carried out special training on safety and quality, clarified key positions, key links and weak points of construction, clarified key on-site control measures, and improved the safety and quality awareness and emergency response ability of construction personnel.
The operation of track bed screening and replacement of new rail is carried out at the same time and in parallel.
On the premise of ensuring safety, we will carefully organize the test of operation methods, accumulate experience in track changing construction, and maximize the construction efficiency.
At 7:30 on July 19, the sky in Gangou station of Meiji line was gloomy and misty.
76 bridges, 2 tunnels, 7 level crossings and 8 stations need to be passed.
