On October 19, 2021, the cold sliding test of the Guangfo Ring Intercity Railway (South Ring) constructed by the Fourth Company of the China Railway Construction Electrification Bureau Group was successfully completed. This indicates that the overall quality inspection of the catenary project of the project has reached the standard and is a full start. Dentsu, hot sliding and the new stage of joint commissioning and joint testing have laid a solid foundation!

The cold skate is about to pass the station turnout

The Guangzhou-Foshan Ring Road winds through the Lingnan land and is an important part of the intercity rail transit network in the Guangdong-Hong Kong-Macao Greater Bay Area. Guangfo South Ring starts from Foshan West Railway Station in the west and ends at Guangzhou South Railway Station. It is 35 kilometers long. There are 5 stations along the way, with a designed speed of 200 kilometers per hour.

The scope of the cold sliding test covers Foshan West Railway Station (excluding) to the main line of Guangzhou South Railway Station and the turnouts and side lines of the station. Guide height, pull-out value, and the presence or absence of bowing, bowing, etc., can eliminate potential safety hazards in time.

Cold skates pass the largest ramp of the whole line (30‰)

In order to ensure the smooth development of the cold sliding test, Guangdong Pearl River Delta Intercity Railway Company, Guangzhou Metro, Beijing Tiecheng and other relevant units coordinated and coordinated closely; the project department adheres to the construction concept of "High-quality Guangfo Ring", based on China Railway Construction " Twelve-character work policy" and "eight-character work requirements" as the guidance, build consensus, strengthen target management, consolidate the responsibilities of all parties, deploy and improve the "Cotline Cold Slip Test Plan" and "Emergency Plan", and build a "leadership + driving command" +Emergency Repair + Observation" all-round organization guarantee system.

Cold skates pass the most beautiful Rainbow Bridge on the entire line

At the cold-slip site, the project department innovatively used video monitoring and sensing devices to help obtain images and data from multiple angles in real time, and to simultaneously verify the operating status of related equipment. At the same time, 18 sets of traffic routes in the station are preset to solve the difficulty of complicated routes and dense turnouts in an orderly manner.

Cold skates stop at Beijiao West Station

"Woo-", with the sound of the siren, the cold roller slowly stopped at Beijiao West Station, and the cold sliding test ended successfully. The young technicians gathered around the inspection vehicle and took a group photo with excitement, and the exhaustion on their faces seemed to disappear in an instant. Most of them have witnessed the memorable scenes from the successful assembly of the first steel column to the "acceleration" growth of the main project, and then to the end of the full-line cold-slip sprint of the Catenary.

At Beijiao West Station, the most eye-catching feature is the 16 sets of giant rigid beams across the top of the platform, the gradually spreading contact net and two rows of parallel steel columns extending outwards. This picture is illuminated by the sun. Glittering.

"Economic development, transportation first. Under the strong radiation of the Guangdong-Hong Kong-Macao Greater Bay Area, high-standard, high-quality, and high-efficiency standardization management is promoted. Make good use of this golden key to open the four power projects with higher added value." China Railway Construction Electrification Bureau Shen Yu, head of the Guangfohuan project, said. The quality Guangfohuan, in his team, embodied in each builder is a real responsibility and responsibility. The project construction team will also continue to build brand confidence, maintain a competitive advantage, and steadily move forward for the next stage of winning the opening and defending battle.
