Changde Daily reporter Pei Weifei/Correspondent Meng Jian Li Chi/Figure July 23, on the road base in Changsha, Changyi, Changyi Changchang high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed high -speed railway. Chang Steel rails slowly laid on the left -line orbit board on the left line of the line, which marks the running of the Changyi Chang high -speed rail.

The entire line runs through the scene.

The Changye high -speed rail is an important part of the two large channels of China from Xiamen to Chongqing and Hohhot to Nanning from Xiamen to Chongqing and Hohhot to Nanning. The line starts from Changde City in the west, and has benefited from the city of Changsha, Changsha City, with a total length of 157.502 kilometers. It has 5 stations in Changde, Hanshou South, Yiyang South, Ningxiang West, and Changsha West. The design speed is 350 kilometers per hour. China Railway 11th Bureau undertakes 403 -hole box beams, 242 -hole T beams, and tasks on the entire line.

In order to ensure the orderly advancement of the Changye high -speed rail, the project team does not wait and take the initiative to actively establish a work contact mechanism with 21 units including the owners, design, supervision and the station sections of the Guangzhou Railway Group. Organize the mobilization of elite soldiers, and to match resources in the partial section. At the same time, the project carefully deduced the construction organization, especially for the details of the long -track entry and laying the same construction at the same time. It has strengthened the normalization of the epidemic and the construction control of the safe and civilized construction.

During the rail paving construction process, the builder adopted the domestic advanced WZ500 rail paving unit operation. Its mechanized degree of mechanization, good system stability, low workers' labor intensity, seams of seamless circuits in one interval, fast rail paving progress every day More than 6 kilometers, the maximum progress can reach 9 kilometers per day.

In response to the actual situation of the high temperature in the summer, the temperature of the rails is too high, which affects the actual situation of the construction of the rail welding and stress dispersing. The project monitor the temperature of the rail temperature in real time for the real -time lines of the rails. Preparation for locking construction also guarantees long -track transportation safety.

In the welding rail construction, the builders used the national advanced inductive fire equipment to carry out seamless rail welding. It uses electromagnetic induction technology to heat the welding joint, overcoming the influence of unprecedented factors such as fire holes, gas quality, and gas flow of flame heating. The heating quality is significantly improved, which effectively improves the quality of the rail welding. The seamless lines formed after the welding of the rail welding will maximize the smoothness of the driving surface, so that the train will ensure that passengers are smooth and comfortable during high -speed driving.

The biggest difficulty in the construction of the Changyi high -speed rail paving is the opening of the Changde to Yiyang section and the Yiyang to Changsha section. As the only rail construction unit across the board, it is necessary to ensure the safety, smooth and controllable during the joint testing during the joint testing of Yishang, but also organize various preparations for the construction of the regular -profit section. "We have held multiple pressures, safety risks, safety risks, personnel and equipment organizations, existing cable construction conditions, material storage and transportation, and mutual cooperation of each unit to successfully complete the target Zhang Jijun, the project manager of the Third Branch of the Changranda Railway.

The Changye high -speed rail is in the aggregate belt of Changsha, Yiyang, and Changde. It can effectively promote the process of Changzhulan integrated. It is the key to form the Hunan high -speed rail ring line. Essence After the completion, 14 cities and states in Hunan will achieve all the targets of high -speed railway, and the transportation structure in northwestern Hunan will be further optimized. The Changye high -speed railway will jointly connect with railways such as Chongqing, Guizhou, Guizhou Zhang Chang, and Changhe, and will become a passenger channel connected to Central, East China, and South China in Chengdu -Chongqing. Social development is of great significance.
