Chongli railway whole line joint commissioning and joint test start
Hebei news network, October 22 (reporter Gao Zhenfa, Li Yanhong, correspondent yuan Yushun and Qu Zhizhong) after nearly three years of hard work by builders, at 10:06 today, with the 55201 first crh380aj-0203 comprehensive inspection train, from Beijing Zhangjiakou high speed railway to daijiaying No.1 Bridge, which connects Chongli railway with Xiahuayuan north station, the first bridge constructed by China Railway 20 Bureau. The joint commissioning and test of Chongli railway was officially launched. The total length of the
Chongli railway is 52.8km, with a design speed of 250km / h. The line starts from Beijing Zhangjiakou high speed railway Xiahuayuan north station and ends at taizicheng station in Chongli district. After completion, it will arrive in Zhangjiakou Chongli Winter Olympic Games area within one hour by high-speed railway from Beijing North Station. It is also an important part of the Beijing Tianjin Hebei inter city railway network.

. It is understood that the joint commissioning and joint test is organized by the operation unit, and the Academy of Railway Sciences carries out the test, with the joint participation of the construction, participation and other units. The joint commissioning and joint test is to ensure the strict test, detection, adjustment and optimization before the opening of high-speed railway. After the static acceptance of the project is qualified, the system and its interface matching relationship are comprehensively tested by means of the comprehensive inspection of the train crh380aj-0203, which is to verify the track, subgrade, bridge, tunnel and other projects as well as the power supply and contact network. , communication, signal, early warning monitoring and other system performance; evaluate whether the comprehensive grounding, electromagnetic environment, vibration and noise data meet the standards, so that the performance of each system and the overall system can meet the parameters required by the design, and provide important technical support for the operation.

in order to ensure the on-line test and inspection of the comprehensive inspection train on time, the second bid project Department of Chongli railway of the second company of China Railway 20th bureau established five track commandos, including track laying, welding dispersion, fine ramming, fine tuning and technical service, to tackle the difficulties and carry out large-scale learning and training simultaneously with the general tone of "undertaking mission, controlling safety and ensuring commissioning" Technical innovation activities such as military and construction of high-quality products ensure that the progress and quality of the project are up to the standard.
in view of the technical requirements of forbidding construction under the high temperature environment of long rail, the builders took the measures of adding white and black to organize the construction, successively solved the technical problems of long rail stress release, high precision of fine adjustment parameters, and provided technical support for the start of joint commissioning and joint test.
