i am on duty during the national day, and the construction will not stop! the construction of beams for the xiangjing high-speed railway is advancing rapidly. at present, 91.58% of the box girder prefabrication has been completed and 76.91% of the box girder erection has been completed. in particular, the xjzq-3 standard project of the xiangjing railway constructed by china railway first bureau took the lead in completing the 605-hole box in the pipe section. the task of prefabricating and erecting beams was a practical tribute to the birthday of the republic.
the xiangjing railway xjzq-3 bid project undertaken by china railway no. 1 bureau has a total length of 29.12 kilometers, including 20.449 kilometers of bridge and culvert projects. there are 12 extra-large bridges, 7 large bridges, 1 medium bridge, and 605 prefabricated double-line box girders. the largest number of bid sections are prefabricated and erected for the entire line of box girders.
during the construction process, the project department insisted on using "intelligence" to improve "quality" and "intelligence" to improve "speed", and put into use a variety of advanced tooling equipment such as intelligent tensioning, intelligent grouting, intelligent spraying, and automated steel bar processing equipment. , which has improved the on-site standardized management level and production efficiency. both box girder prefabrication and erection have been completed with the first place in the entire line.
since the beam erection construction of the xjzq-3 mark of xiangjing railway began in late october last year, it has successively overcome many unfavorable factors such as the long transportation distance of the box girder, the multiple and complex working conditions along the trackbed, and the girder construction adjacent to the business line, and has actively opened up the box girder. there are three major links: prefabrication, transportation and erection. at the same time, it increased resource investment, strengthened the operation and maintenance of mechanical equipment, and carried out labor competitions with various node goals as tasks. it once set a record of the highest single-machine box girder with 6 holes per day across the entire line.
in the next step, the xiangjing railway project will strictly control quality, implement safety production responsibilities, focus on the target tasks, coordinate the process, and make every effort to speed up the production pace. it will promote the construction of the remaining projects with high quality, high standards and high efficiency, and launch a sprint towards the annual task target. .
xiangjing railway is an important part of the hohhot-nanning corridor, one of the main corridors of my country's "eight vertical and eight horizontal" high-speed railways. after its completion, it will accelerate the construction of a two-hour high-speed rail living circle in hubei province, further improve the high-speed rail network along the river, and promote the development of resources along the line. it is of great significance to create an eco-tourism circle in western hubei and to quickly connect the "yijingjing" metropolitan area with the xiangyang metropolitan area.
