On March 5, 2022, the first 500-meter-long steel rail of the Guinan high-speed railway line successfully arrived at the Guinan high-speed railway Hechi track laying base of the China Railway 14th Bureau, marking the construction of the first high-speed railway in Guangxi with a design speed of 350 kilometers per hour and entering the long-track storage stage. The track laying laid the foundation for the whole line.

According to the construction plan, all track laying tasks will be completed within two months, which is half of the normal construction period. To this end, the 14th Bureau of China Railway has carefully organized and planned scientifically to overcome the unfavorable conditions such as rainy weather, undulating terrain, and a steep slope of 20‰, and completed the track laying of Hechi with an area of about 67 mu and a storage capacity of 278 kilometers four months ahead of schedule. The construction of the base meets the requirements for loading, unloading and storage of all long rails in the Guangxi section.

The rail transportation line is complex and undulating, it needs to cross the existing Guizhou-Guangxi Railway, and has to go downhill through the large crossing of the Jinhuan Highway, and then transport it uphill to the track laying base, which brings safety risks to rail transportation, loading and unloading. The 14th Bureau of China Railway has increased its investment. By strengthening the protection of the crossing in advance, three locomotives are simultaneously towed to allow the long-rail train to "climb" up a steep slope of 20‰ to ensure transportation safety. At the same time, they carried out intelligent transformation of the original gantry group crane, which improved the work efficiency and kept the 500-meter-long steel rail straight and ensured the quality of the track laying.

It is reported that after the completion of the Guinan Railway, the journey time of the high-speed railway from Guiyang to Nanning will be reduced from the current 5 hours and 25 minutes to less than 2 hours. The road network structure in the west is of great significance to promote the development and utilization of tourism resources along the route, introduce passenger flow and expand foreign exchanges.

On the morning of March 6th, with the 1000-ton bridge erecting machine of China Railway 14th Bureau accurately erecting a box girder on the pier of Shanghai-Suhu Qingpu Bridge, marking the first "thousand-ton" bridge erecting machine of China Railway 14th Bureau The successful first one further highlights the industry leading advantage in the field of paving.

The main line of the Shanghai-Suhu High-speed Railway is 163.708 kilometers long and has a maximum design speed of 350 kilometers per hour. It is the backbone line in the intercity rail transit network in the Yangtze River Delta. In order to meet the construction requirements, the fifth company is equipped with one 1000t bridge erection machine, one 1000t beam transporter and two 500t gantry cranes.

As the instruction was issued, the newly designed thousand-ton beam transport vehicle steadily "feeds" the one-hole simply supported box girder to the bridge erecting machine. In order to ensure the efficient and orderly progress of the beam construction, the five companies scientifically organize and plan ahead, go through the inspection procedures in advance, select professional and technical personnel with rich experience in transporting beams, conduct pre-job professional training, and innovatively develop through the beam branch. After passing the online examination system training, you can start your job.

According to Liu Yuanbao, manager of the beam erection branch of the fifth company, the 1000t/40m beam bridge erecting machine equipment has the advantages of low overall height, strong tunnel-passing ability, fast hole-passing speed, convenient transfer between bridges, high level of informatization, and strong adaptability, etc. The advantage is that it belongs to the more advanced beam erection equipment in China. The 1000t beam transporting truck used with it meets the construction requirements of the beam transporting through the tunnel. The equipment adopts a modular design, which is easy to install and disassemble, with a high degree of informatization and convenient fault diagnosis, which can reduce the hidden danger of construction safety and improve the work efficiency.

It is reported that after the completion of the Shanghai-Suhu High-speed Railway, it will become an important railway transportation channel connecting Shanghai, Suzhou, Huzhou and other core areas of the Yangtze River Delta. It is of great significance to promote the integration of the Yangtze River Delta region and the modernization of the southern Jiangsu region.

On March 5th, in the Jilai High-speed Railway Project Department of the Electrification Company, the professional builders of the second company, the construction company, and the Jilai high-speed railway project of the Electrification Company gathered together, and the three labor competitions pressed the start button at the same time.

Jilai High-speed Railway is a key project in Jinan City, and it is also the first high-speed railway in the city, which has attracted much attention from all walks of life. 2022 is the year of the opening of the Jilai high-speed railway, and it is also the decisive year for the construction units of the group company Jilai high-speed railway.

In the face of the closing construction period of the joint commissioning and testing of the entire line on August 10, the group company's four power construction majors, ballastless track construction majors, and station building construction majors are all facing enormous pressure.

In order to ensure the completion of the task, all majors combined with the actual situation, under the unified arrangement of the bureau, innovated the organizational form of labor competition, the offline project carried out a 30-day labor competition around the construction of the ballastless track, the station building project carried out a 60-day labor competition, and the four power construction projects were carried out. A 100-day labor competition was held, and military orders were issued to complete 65 million, 52.83 million, and 380 million.

Time is tight and tasks are heavy. All the employees participating in the construction are using scientific organization and meticulous management to anchor the competition goal of "guaranteeing safety, quality, opening, and efficiency", and in-depth development of value-added, innovative, critical and skilled labor competitions to ensure the completion of the competition. construction tasks.
