Trans high speed transfer of transmission lines to speed up the construction of Fuzhou Xiamen high speed railway

News from our newspaper (reporter Huang dunliang, correspondent Li Yipeng) recently, in order to cooperate with the construction of Fuzhou Xiamen high speed railway project of China Railway Group, State Grid Quanzhou power supply company carried out the power outage and relocation construction of some pole sections of 220 kV transmission line from December 2 to 5, with a construction period of 4 days. After the completion of the project, the layout of Fuzhou Xiamen express railway network will be improved to alleviate the problem of passenger flow saturation of Fuzhou Xiamen high-speed railway, which is of great significance to promote the social and economic development along the line.

it is understood that the power transmission line relocated this time is located above the entrance of Shishi exit of Quanzhou Ring Expressway, crossing with the proposed Fuzhou Xiamen high speed railway, which does not meet the requirements of the railway for the safe distance of the iron tower and the requirements of the conductor for the track height, so it is necessary to upgrade the iron tower or cable into the ground. In addition, when removing the line crossing the expressway, the expressway needs to be temporarily closed for 4 times, each time for about 15 minutes, with short effective construction time and large construction difficulty coefficient. A 6031 a 6031 Quanzhou power supply Co., Ltd. formulates plans for line outage, construction transformation, etc. in advance, and organizes personnel to survey the site for many times, refine the construction scheme, increase the construction force, advance safely and orderly, and try to shorten the construction time. In order to ensure the safe passage of vehicles, the company strengthened the linkage with the high-speed management department, and carried out the control at the crossing point of Jinshi high-speed, and started to set up speed limit boards, guide signs, closed signs and parallel road running signs a few kilometers before and after the construction, and timely issued traffic control information according to the construction progress to avoid road congestion.

in order to ensure the safety and stability of the power grid, the company set up 9 power protection teams, sent 95 line inspectors, sent 46 emergency repair vehicles, and arranged personnel to garrison the site of 5 key power protection lines and 10 external hidden danger points, carry out round inspection, and build a safety barrier for the power grid.
