At 4 o'clock in the morning on March 21, 2023, the Guinan Project Department of the Sixth Company of China Railway Fifth Bureau organized more than 200 construction workers to successfully install a set of turnouts on the Liunan Passenger Dedicated Bamboo Line after 320 minutes of continuous operation. The design location of the South Passenger Dedicated Downline and the newly-built Guinan Downlink Passenger Train Connection Line and the opening of the line on time mean that the Guinan Railway is introduced into the Nanning Junction Project Xiangzhu Line. The Guinan High-speed Railway, which is in charge of the construction by the Guinan Project Department of the Sixth Company of China Railway Fifth Bureau, introduced all the driving paths of the Nanning Hub Nanning Station and Nanning East Station to the existing lines and stations, providing conditions for the scheduled opening and operation of the Guinan High-speed Railway.

At 22 o'clock on March 20, 2023, outside the fence of the bamboo line of the Liunan Passenger Car, more than 200 operators and more than 300 sets of construction equipment were ready to go. The paving construction battle started. At 23:10, as the construction blockade order was issued, the on-site commander gave the construction order, and the operators and construction machines quickly went on the road, and the construction of the 2# turnout of the Xiangzhu Line Station kicked off. From sawing rails, removing lines, leveling roadbeds, setting up slideways, pushing turnouts into place, dismantling slideways, and then to rail closure, small machine track alignment, tamping and stabilization, track bed arrangement, and finally to catenary adjustment and communication and closing equipment Debugging, the whole process is carried out in an orderly manner. In the end, after 320 minutes of continuous work, the turnout construction was successfully completed, and the line was opened at 4:30 a.m. on the 21st to resume traffic. The Guinan High-speed Railway introduced the Nanning Junction Project to the Xiangzhu Line. The second-level construction of the turnout insertion was successfully completed. Provide conditions for the scheduled opening and operation of the Guinan High-speed Railway.

Due to the needs of design and construction, Guinan high-speed railway introduces Nanning hub and has 4 connection points with the existing business lines. The driving paths are respectively connected to Nanning Station and Nanning East Station. Undertake construction. The main construction content is to insert and lay 3 sets of turnouts on the Nanguang Passenger Dedicated Line, dismantle 1 set of turnouts, build a 1.25-kilometer Guangqin connection line, build a new safety line, rebuild a 2.8-kilometer Liunan Passenger Dedicated Uplink Line, and lay 16 sets of new turnouts. At the same time, rebuild the throat area lines of No. 1 to No. 8 in Nanqin Field of Nanning East Railway Station, and temporarily replace No. 1 to No. 8 wide sleeper boards. Since November last year, it took 4 months. The Guinan project department planned in advance according to the design plan, actively strengthened coordination and communication with the owner, design and Nanning Bureau, and promptly requested the mobilization of existing line construction technical elites to optimize the construction organization design. , overcame practical difficulties such as difficult construction coordination, high safety risks, and short operating time, and ensured the smooth completion of the construction node goals at each stage. Up to now, all turnout laying, line laying and wide pillow board replacement construction have been successfully completed, and the remaining projects are expected to be fully completed by the end of March.

Since the Guinan Project Department of the No. 6 Company of China Railway No. 5 Engineering Bureau entered the site, it has insisted on taking the project party building as the guide, creating high-quality projects and safety projects as the carrier, and taking high-standard management as the concept to steadily advance the progress of the project. The project department focused on learning, publicizing and implementing the spirit of the 20th National Congress of the Communist Party of China, adhering to the culture of pioneering pioneers and carrying forward the spirit of the ace army, and carried out in-depth practical activities on the theme of being a pioneer, striving for first-class, and bravely creating benefits, and completed all stages as scheduled Permanent construction and production tasks, laying the foundation for the smooth progress of subsequent construction.Editor / He Yurong
