China News Service, Jiujiang, July 18th (Reporter Wu Pengquan) With the completion of the last ballastless track slab on the 18th, it marks the completion of the construction of the ballastless track slabs on the entire An (Qing) Jiu (Jiang) Railway, and is for the subsequent laying of tracks. Through creating favorable conditions.
The Anjiu Railway starts in Anqing City, Anhui Province and ends in Jiujiang City, Jiangxi Province. The existing Lushan Station is introduced. The main line of the new line is about 198 kilometers long. The whole line adopts the new type CRTS III ballastless track independently researched and developed by China with complete intellectual property rights. .
According to the construction party China Railway Fourth Bureau, CRTS III slab ballastless track technology is still in the primary application stage in the construction of China's passenger dedicated railway, and the technical standards are high.
Due to the sensitive performance of self-compacting concrete, segregation and unstable performance during construction, builders monitor the performance of concrete in real time, and adjust the poured concrete in the first time, which greatly reduces the amount of concrete loss.

The reporter learned that during the construction process, the construction and construction units coordinated the configuration of materials, personnel and equipment in advance, re-measured the beam surface elevation, and performed multiple fine adjustments to the CP Ⅲ point layout. The project department’s technology and test personnel monitored the entire process to ensure the entire line The construction of the ballastless track was successfully completed.
It overcomes the difficulties of tight construction period, high risk, and difficult connection of construction organization and procedures, and ensures that each procedure of the ballastless track is closely connected, so that the base plate of the ballastless track on the whole line can meet the acceptance standard at one time.
The railway department stated that the Anjiu Railway is designed to have a speed of 350 kilometers per hour, which is one of the projects of the Beijing-Hong Kong (Taiwan) channel of the national "eight vertical and eight horizontal" high-speed railway network.
