Safety on China's Rails
References
China is the country of the "fast track" over long distances. With its ever-expanding high-speed railway network, the country aims to connect major cities, increase traffic capacity, and strengthen the domestic economy by integrating neglected regions. Amid all the "faster" and "further," safety should not be overlooked.
Eight high-speed rail networks connecting north and south as well as east and west have been in operation for several years. These routes are now in a condition that requires maintenance and repair. For the preventive reinforcement of the track slabs as well as the foundation of the switch and base plates, the fischer epoxy resin mortar FIS EM 390 S is used. The work concerns the main connections of the rail network with the high-speed routes Shanghai-Hangzhou, Nanjing-Hangzhou, Beijing-Shanghai, Hangzhou-Ningbo, and Hangzhou-Changsha.

Project Profile

Project;
Maintenance and repair of the high-speed networks of the Chinese railways
Scope:
Preventive reinforcement of the roadway slabs as well as foundation of the switch and base plates
Number of fischer cartridges:
more than 250,000 cartridges of the fischer epoxy resin mortar FIS EM 390 S
Rail length:
25,000 km
The project is led by the China Railway Shanghai Bureau. “Our FIS EM 390 S meets these high demands with its various properties, such as its strong holding forces as well as water, heat, and moisture resistance, whether in frost or warm temperatures,” describes Jiang Zong, Managing Director of fischer China. While in the northern and northeastern provinces of China temperatures can drop well below zero with biting cold, it can become extremely hot and humid in the south and along the eastern coastal regions. This must be taken into account in the planning, maintenance, and monitoring of infrastructure and vehicles. The fischer injection mortar FIS EM 390 S achieves particularly high load capacities in concrete and withstands extreme conditions, as in the application case in China. It is used with reinforcing bars and suitable system components, such as the fischer anchor rod FIS A or the fischer internal thread anchor RG M I. The epoxy resin mortar can also be used in water-filled drill holes as well as seismic applications. Additionally, it offers high corrosion and fire safety. Overall, it is a safe choice for track maintenance in China, but also for fastening new rails or underwater installation, for example.
The responsible parties impose extremely strict requirements on the performance of the products to ensure the effectiveness of the anchoring components even in the event of cracks in the roadway or base plates.
