On the afternoon of July 1, Wang Tongjun, member of the party group and deputy general manager of China State Railway Group Co., Ltd., went to the XCTJ5 standard project of Xicheng Railway of China Railway First Bureau for investigation and guidance. Wang Zaiguang, Secretary of the Party Committee and General Manager of Lanxin Railway Ganqing Co., Ltd., Han Yun, Commander of the Cooperation Headquarters, Zhang Lin, General Manager of China Railway First Bureau, Yan Qundong, Assistant General Manager, the main leaders of the Fifth Inspection Team, the Fifth Company, and the Track Operation (Xinyun) Company, as well as the design unit, supervision unit and relevant persons in charge of the project accompanied the investigation.
▲Research site
At the construction site of the project, Wang Tongjun successively inspected the project progress, standardization promotion and on-site safety and quality control of the project cooperation tunnel exit, sleeper yard and small prefabricated component factory. At the exit of the cooperative tunnel, he inspected the construction quality of the second lining of the tunnel and the excavation of the tunnel face, and listened to the report of the project leader on the introduction of the whole bid section project, construction progress, 2024 implementation plan, and the promotion of process tooling. Subsequently, the sleeper yard and the intelligent prefabricated component factory were investigated, the promotional video was watched and the production process was visited on site, and the intelligence degree of the small prefabricated component factory of China Railway First Bureau and the intelligent production line of double-block sleeper were highly recognized.
▲Investigate the processing line of the intelligent prefabricated component factory
It is reported that since the entry of the 5 bids of Xicheng Railway, it has strictly implemented the deployment arrangements of China Railway Group and Ganqing Company, focusing on the overall goal of "green, high-quality, intelligent and humanistic" project construction, and establishing the management concept of "starting from a high starting point, promoting high-standard and high-quality construction", widely applying digital intelligence technology and green technology, promoting green construction, promoting standardized management in depth, and striving to create high-quality projects.
▲Investigate the intelligent sleeper field
The exit section of the cooperative tunnel has a length of 2,490 meters, of which 1,185 meters are fourth-grade surrounding rock, accounting for 48%, and 1,305 meters are fifth-grade surrounding rock, accounting for 52%. The shallowest burial depth is 12 meters, and the maximum burial depth is 192 meters. In tunnel construction, a complete set of "one hole and ten lines" is adopted to promote the standardization of the construction process.
▲China Railway First Bureau Xicheng Railway Project Prefabricated Component Factory
The project actively responded to the requirements of "intelligence, digitalization, informatization, standardization and factory" advocated by Ganqing Company, and built an intelligent small prefabricated component factory covering an area of 98 acres in only 40 days. The prefabricated plant is the first small-scale prefabricated component factory put into production on the whole line of Xicheng Railway, with a total prefabrication volume of about 76,000 square meters, and undertakes the production and distribution of small components from one to eight standards. The project has gradually explored a set of mature production and operation system, that is, one system, two lines, three intelligent connections and seven units. "One system" is an information control system to realize the information integration of material management, production management, finished product management and cost management. The "two lines" are the two production lines of the prefabrication plant, which respectively set up a special intelligent production line for cover plates, and a hybrid intelligent production line covering various product types such as hollow hexagonal blocks and concrete protective fences. "Three intelligent linkage" is the intelligent production line from the information precision CNC cloth, to the intelligent automatic demoulding, to the robot automatic palletizing three links to form an intelligent linkage. The "seven units" are the whole process of the production line is decomposed into seven units: automatic cloth vibration, automatic stacking and destacking, constant temperature steaming and curing, intelligent demoulding, automatic mold cleaning, intelligent palletizing and automatic oil injection. The prefabricated plant has independently developed a complete set of fully automated production lines and spray steaming and curing systems to replace traditional manual production, which has the highest degree of intelligence, the largest factory scale, the largest production capacity, and the largest variety of compatible production products, and has achieved a huge breakthrough in construction efficiency and production cost.
▲ China Railway First Bureau Xicheng Railway Project double-block sleeper intelligent production line
The sleeper yard covers an area of 80 acres and undertakes the prefabrication and transportation of 428,940 double-block sleepers. The production of double-block sleepers adopts intelligent production line equipment, the application of the Internet, big data, cloud computing and other cutting-edge high-tech, and the main stations are divided into automatic truss welding processing, intelligent stirrup processing, mold cleaning, release agent spraying, casing installation, truss molding, concrete distribution, kiln entry, steam curing, flip demoulding, sleeper detection, sleeper palletizing. Through the use of intelligent production equipment, the labor intensity of operators and the safety risk of the construction process are reduced, and the product quality and stability are improved.
