Recently, in the heartland of Europe, a steel dragon several hundred meters long precisely stopped 200 meters underground. The "Letteria" shield machine, independently developed by China Railway Equipment, has just taken the first hard bite of the S tunnel in a certain railway double track project. Under the dual pressure of geological seepage and harmful gases, this heavy equipment labeled as "Made in China" showcased the hardcore strength of China's high-end equipment to the European infrastructure market with a daily excavation speed of up to 32.4 meters.

Complex geological breakthrough

The geological conditions of the S tunnel are extremely complex, with a maximum burial depth of 200 meters, requiring frequent crossing of alternating layers such as clay and sandstone. In response to the risks of water seepage and harmful gases, China Railway Equipment strictly follows EU standards for customized design, equipped with an intelligent excavation control system, and adjusts parameters in real time to ensure safety control while also meeting low-carbon and environmental protection requirements.

Local operation and maintenance escort

China Railway Equipment relies on its localized operation layout in Europe, closely following equipment debugging and on-site operations throughout the process. Through a 24/7 rapid response mechanism, we provide refined operation and maintenance support to ensure that the 'Letteria' always maintains the best working condition during long-distance excavation, achieving efficient and stable progress since the start of excavation.

Regional connectivity acceleration

After the full completion of the railway double track, it will completely reshape the local land commuting map. A more convenient transportation network will connect cultural, tourism, and commercial resources, injecting strong impetus into the coordinated development of regional economy, and deeply embedding Chinese shield tunneling machines into the infrastructure bloodline of European connectivity.Editor/Gao Xue
