On August 10, at the construction site of the special maglev tourism line in Fengcheng, Guangdong Province, the last 10-meter maglev track panel was steadily laid on the Changlong Bridge by the builders of the 11th Bureau of China Railway, marking the completion of 1500 maglev tracks on the first medium and low speed maglev tourism line in Qingyuan, Guangdong Province. The track of the whole line is connected.
As a key construction project of Guangdong Province and Qingyuan City, the main line of the initial project of Qingyuan Maglev Tourism Line is 8.1 kilometers long, using medium and low speed maglev trains with a design speed of 100 kilometers per hour. The Third Company of the 11th Bureau of China Railway undertakes the task of laying the track of the whole line. The main function of the line is to serve the tourist attractions of Changlong Theme Park. There are three stations, namely, Yinzhan Maglev Station, Lianhu Station and Changlong Station. Changgang Station and Yinzhan Parking Lot are reserved. After the completion of the project, the rapid access between Guangqing Intercity Yinzhan Station and Changlong Theme Park can be realized.
Due to the strict construction requirements of driving speed and track alignment standards, Qingyuan Maglev Tourist Line cancels the measurement reference hole, optimizes the pouring materials of the bearing platform, and implements new design concepts such as standardized manufacturing and construction of the track panel. At the same time, due to the special working conditions of complex sections such as high pier section, tunnel section, adjacent existing line construction, overpass and underpass of existing busy railway and highway trunk line, which have not been faced by maglev line construction for the first time in this project, especially the limited space for track panel and concrete hoisting and transportation in complex sections, the existing equipment for traditional maglev track laying can not meet the normal construction requirements. There is no successful experience to draw lessons from, and the project construction is extremely difficult.
To this end, the company's joint project set up a scientific and technological research team, successfully set up the project "Research on High Efficiency Construction of Medium and Low Speed Maglev Track Engineering and Installation and Construction Technology of Maglev Turnout", and completed various research and development and test work from the aspects of process optimization, equipment development and tool development. The problem of low efficiency of material transportation and construction in complex areas has been solved smoothly. According to statistics, the project has applied for 18 patents, and many achievements have won provincial and ministerial awards for excellent construction methods and scientific and technological progress.
The last scene
of maglev track panel hoisting In the process of laying maglev track panel, the project also gives full play to the advantages of BIM technology. In the research and development of equipment tooling, the conceptual equipment tooling is designed by BIM technology to assist the front-end verification of research and development, which effectively reduces the cost of trial and error. In the actual construction, the builders use BIM technology to simulate the construction conditions of complex sections, deepen the understanding of project managers and workers on construction technology, and improve the management precision of project progress, quality and safety.
According to Zheng Wu, the construction manager of Qingyuan Maglev Track Project of the 11th Bureau of China Railway, fine adjustment will be carried out after the completion of the laying of the maglev track panel, so that the track direction and elevation error will be controlled at plus or minus 0.5 mm to ensure the smoothness of the line, so that the maglev train will run more smoothly and passengers will have better comfort when taking the train. The
installation of maglev fasteners
by operators will be extended to the east and west in the later stage of Qingyuan Maglev, creating a special eco-tourism line connecting several characteristic towns and resorts in series, which will become an important supplement to the integrated development of Guangqing Rail Transit. After all of them are opened to traffic, the tourism resources in southern Qingyuan will be strung into a chain, which will further promote the integration of southern Qingyuan into the Dawan District.
