The Guangzhou Zhanjiang high-speed railway with a speed of 350 kilometers per hour has entered the countdown to its opening and is currently in the trial operation stage. It is expected to be officially put into operation before the end of this year. On December 10th, the reporter boarded a trial run train at Baiyun Station in Guangzhou for an early test ride. The trial run train departed at 9:00 am and arrived at Zhanjiang North Station in the central urban area of Zhanjiang at 10:32 am, with a total travel time of 92 minutes. The "soundproof tunnel" makes the high-speed railway quiet. The main line of Guangzhan high-speed railway is 401 kilometers long, with a designed speed of 350 kilometers per hour. The terrain, landforms, and geological conditions along the line are complex, and the bridge tunnel ratio of the entire line reaches 76.8%. At 9:00 sharp, the trial train left Baiyun Station in Guangzhou and soon passed the the Pearl River Fourth Line Bridge. Fu, the commander of the Guangzhou Zhanjiang Section of the Guangzhou Engineering Construction Headquarters of China Railway Administration Group Co., Ltd., introduced that the main line of the the Pearl River four line super large bridge is 4.9 kilometers long. During the construction, the original the Pearl River East Bridge on the Guangmao Railway was demolished by optimizing the design, adopting the scheme of separate construction, activation and utilization, and the original the Pearl River West Bridge was retained, and the "misty rain on two bridges" landscape was preserved, so as to achieve a win-win situation for the protection of historical buildings and the construction of railway hubs. Subsequently, the train passed through the "soundproof tunnel" of the Guangzhou Zhanjiang high-speed railway. The Luo Village Wing Chun Sports Park, adjacent to the "soundproof tunnel", covers an area of about 200 acres with a green coverage rate of over 70%. The wetland islands, small bridges, and flowing water in the park form a beautiful ecological picture. The high-speed train shuttles through the "soundproof tunnel" of the bridge, while the tranquility outside the bridge remains unchanged. This fully enclosed sound barrier project is not only the first application in the 350 kilometer per hour high-speed railway project in the Guangdong Hong Kong Macao Greater Bay Area, but also provides a new solution for noise reduction in high-speed railways in densely populated urban areas. After leaving the "soundproof tunnel", the trial operation train raced all the way through the Zhanjiang Bay railway tunnel. He Ziliang, the person in charge of the Zhanjiang Bay Railway Tunnel Project of China Railway 14th Bureau, introduced that this is one of the control projects for the entire Guangzhou Zhanjiang high-speed railway line. The tunnel passes through the sea and cities, with high risks. The shield tunneling machine tailored by the technical team overcomes technical difficulties such as long-distance complex underwater formations and severe tool wear. A series of technological innovations have been designed and implemented, effectively improving the construction efficiency of the shield tunneling machine in complex formations. During construction, the intelligent management system for shield tunneling was also applied, resulting in multiple scientific research and innovation achievements, and the entire line maintained millimeter level control of ground settlement. In the future, high-speed trains traveling up and down can cross tunnels in about 3 minutes. The reporter from the "350" circle of friends in western Guangdong saw on the train that the Guangzhou Zhanjiang high-speed railway will launch a variety of special dishes ranging from 20 yuan to 40 yuan, such as braised chicken and pineapple meat, which can not only reflect the abundant resources of Zhanjiang, but also showcase the local food culture; In terms of tea drinks, we combine the rich fruit resources and coastal style of Zhanjiang to launch a series of salty fresh fruit tea drinks - Xianhuangpi Jinjin tea and domineering pineapple tea, allowing travelers to taste the natural and fresh flavors of Zhanjiang first on their way to the mountains and seas of western Guangdong. The train runs for 92 minutes and finally arrives at the newly built Zhanjiang North Station. Zhanjiang North Station is located on the west side of the original Zhanjiang Airport in Xiashan District, Zhanjiang City. The total construction area of the station building is 105000 square meters, and it can accommodate 5000 people waiting for trains at the same time. Zhang Hongyun, the design director of Zhanjiang North Station of China Railway's Guangzhou Zhanjiang High speed Railway, introduced that the station building's shape is taken from the "Bauhinia Zhanfang", and the roof stretches out like petals, symbolizing the prosperity of the city. The ceiling of the waiting room is made of thousands of aluminum plates pieced together in the shape of a Bauhinia flower, with curves like waves and flowing light and shadow, solidifying the millennium charm of the ancient port and showcasing the exquisite craftsmanship of contemporary craftsmanship. The Guangzhou Zhanjiang high-speed railway is an important component of the national "Eight Verticals and Eight Horizontals" high-speed railway network and a 350 kilometer per hour coastal railway passenger transport corridor. It is also the most complex, longest, and largest investment railway project independently invested and constructed by Guangdong Province. It is a high-speed railway connecting the Guangdong Hong Kong Macao Greater Bay Area, Hainan Free Trade Port, and Beibu Gulf Urban Agglomeration. After the completion and opening of the project, the travel time between the central urban areas of Guangzhou and Zhanjiang will be shortened to about 1.5 hours, greatly improving the spatial and temporal distance between the western Guangdong region and the Guangdong Hong Kong Macao Greater Bay Area. This injects new vitality into the transportation development of the Guangdong Hong Kong Macao Greater Bay Area, and is of great significance in supporting the 'Millions of Projects' and promoting regional coordinated development. ”Zheng Wei, a section engineer from the Engineering Management Department of Guangzhan Railway Company, said.
