The west section of Beijing Qinhuangdao Railway is flat, the eastern hills are undulating, the population along the line is dense, and the agriculture is developedNorth ChinaOne of the secondary trunk lines of traffic.Beijing Qinhuangdao Railway is the period of China's "Sixth Five Year Plan"Key constructionA new railway line.It starts from Beijing in the west, passes through ShuangqiaoAbundant, EastqinghuangdaoShanhaiguan, 341km long.It is a double track electrified railway.The west end of the line is connected with Fengsha Electrified Railway, mainly responsible forQinhuangdao PortTransport task of launching, and diversion at the same timemsts Part of the direct traffic volume is an important channel and shortcut for the northern route of Shanxi coal outward transportation.The annual design traffic volume is 87 million tonsSouth China Economic development and foreign trade are of great significance.The Beijing Qinhuangdao Railway was officially started in March 1982. In the second half of 1984, it was simply opened and began to transport coal. In December 1985, the whole line was officially put into operation.
In order to improve the quality of the project, they have widely adopted new processes.Project DepartmentComputerized management has been fully implemented, new modern construction facilities have been purchased, and the construction process of "four in place at one time" has been adopted (that is, pillar assembly is in place at one time,Portal structureThe installation shall be in place at one time, the guide erection shall be in place at one time, and the suspension adjustment shall be in place at one time);Realized the "four modernizations" construction (that is, pre assembly industrialization, calculation computerizationOperation standardizationInstrumentation);OptimizedAdditional wireErect new technology and change traditionalSetting outThe mode iswindlassTransmission and tension erection enable the erection of additional conductors to reach the standards of tension and sag at one time, and under the guidance of design standards, the technical difficulties such as the failure of Douhe Bridge and overhead catenary to pass normally have been successfully overcome.
Strict organization and scientific construction method not only accelerate the construction speed, but also ensure the project quality.advancedCatenarytestingEquipment inspectionThe results show that the first pass rate of the quality of the electrification project in Langqin section has reached 100%, and the excellent rate is more than 95%.
fromChina Railway ElectrificationThe Beijing Qinhuangdao passenger transport corridor contracted by the first company is upgraded to LangwopuqinghuangdaoSection electrification project was successfully opened.This marks that the whole Beijing Qinhuangdao Railway has been electrified and connected with the Qinhuangdao Shenyang Railway to become the North China RailwayNortheast ChinaThe first fast passenger channel of Beijing, the electrified train starts from BeijingQinhuangdao Shenyang Passenger Dedicated LinetoShenyangIt will not exceed 5 hours.
The electrification reconstruction project of Beijing Qinhuangdao passenger transport corridor is the first large-scale speed increase reconstruction project of 160-200 km for the first operation line in China. China Railway Electrification First Co., Ltd. is responsible forqinghuangdaoSection electrification construction.The project task is extremely arduous.First, the time is tight and the task is heavy.The total length of the Langqin section is 132km, with an investment of 130 million yuan, and the actual construction period is 6 months ahead of the original plan;Secondly, the technology is new and the standard is high.The third is Beijing Qinhuangdao Linetraffic density Large, specialized transportation and high safety requirements.
