China News Service, Guangzhou, November 6th (Guo Jun, Qian Tianyun, Wei Xiangyu) At 9:28 on November 6th, with the precise placement of the first T beam with a length of 32 meters and a weight of 135 tons, China Railway 25th Bureau The Guangzhou-Zhanjiang High-speed Railway Guangzhou-Zhuhai-Beijing-Guangzhou Link Line Bridge under construction has entered the construction stage of beam erection, laying a solid foundation for the rapid progress of subsequent construction.
The Guangzhan high-speed railway is an important part of the 350 km/h coastal passenger passage in the national "eight vertical and eight horizontal" high-speed railway network, and it is also the largest high-speed railway project invested by Guangdong Province in recent years.
The main line of the project is 400.111 kilometers long. The line leads from Guangzhou Station, passes through cities such as Foshan, Zhaoqing, Yunfu, Yangjiang, Maoming, Zhanjiang, etc., and finally ends at Zhanjiang North Station.
The Guangzhou-Zhuhai-Beijing-Guangzhou Link Line constructed by the China Railway 25th Bureau is a prerequisite and key project for the reconstruction of the main line of the Guangzhan high-speed railway. The line is 3.429 kilometers long and has 9 special structures. The Beijing-Guangzhou ascending line and the Guangqing Expressway pass through the Wuhan-Guangzhou high-speed railway. The construction is 2.7 kilometers away from the existing business line. It has the characteristics of high construction risk and strict protection standards.
According to Sun Lie, the person in charge of the on-site beam erection of the China Railway 25th Bureau, the Guangzhou-Zhuhai-Beijing-Guangzhou Link Bridge is about 3.04 kilometers long and requires a total of 71 beams. The construction period is very tight, and the construction organization is extremely demanding. The operation is close to the existing Guangzhou-Zhuhai Railway, and the construction safety risk is high.
In order to ensure the smooth erection of the first T beam, the construction party strictly implemented the epidemic prevention and control measures, and carefully organized and scientifically constructed the construction according to the characteristics of the adjacent existing lines.
Before construction, make technical disclosures in advance for T beam prefabrication, substructure construction, erection, etc., and arrange full-time safety personnel to keep an eye on the safety management of machinery and equipment, conduct safety training for team members, and increase the investigation of potential safety hazards; During the construction, the relevant data of the substructure on the site was checked in real time, which ensured the accuracy of the parameters such as the anchor bolt hole of the T beam support and the lateral connecting plate, and ensured the quality of the beam and the construction safety.
It is reported that the Guangzhan high-speed railway is an important part of the high-speed railway corridor connecting the Guangdong-Hong Kong-Macao Greater Bay Area, the Hainan Free Trade Zone and the Beibu Gulf urban agglomeration.
It is not only an important measure to implement the national major development strategy, but also a strong support for Guangdong Province to build a new regional development pattern of "one core, one belt, one area".
After the Guangzhou-Zhanjiang high-speed railway is completed and opened to traffic, it will fill the gap of no ballastless high-speed railway in the coastal areas of western Guangdong, and will become an important carrier to drive and guide the urban system and social development along the line.
By then, the central urban area of Guangzhou and the central urban area of Zhanjiang will be able to reach each other within 90 minutes, which will promote the integration of Yangjiang, Maoming and Zhanjiang in the coastal areas of western Guangdong into the Guangdong-Hong Kong-Macao Greater Bay Area, and help Guangdong achieve the goal of "city-city-to-city high-speed rail with a speed of 350 kilometers per hour". .
