China Railway Equipment Assists in the Construction of Hamburg Thermal Tunnel Project in Germany

The small diameter earth pressure shield machine "China Railway 1144" developed by China Railway Equipment has successfully launched in the Hamburg thermal tunnel project in Germany, marking the first time Chinese shield products have entered the German market.

The Hamburg Thermal Tunnel project in Germany starts from the south side of the Elbe River and will cross the Elbe River to reach the North Bank Port New City. After completion, the project will effectively enhance the local winter heating capacity in Hamburg. The excavation mileage of a single shield machine is about 1165 meters, and the tunnel geology is mainly composed of gravel, sand, sand, clay, and sedimentary limestone. The maximum water and soil pressure is about 4.5 bars.

Based on the characteristics of high water pressure and high settlement accuracy control in the project, China Railway Equipment has tailored the "China Railway 1144" earth pressure shield machine to meet the needs of customers. The excavation diameter is 4.57 meters, and the total length of the equipment is about 278 meters. Multiple advanced technologies have been integrated. At the same time, for the first time, China Railway Equipment has adopted personalized measures such as independent human compartment design that meets CE standards and rotary segment cars on small diameter shield tunneling, further improving the safety of the equipment Comfort and environmental friendliness. To ensure the smooth implementation of assembly services for this project, after the equipment arrived at the site, China Railway Equipment adopted a localized service team to quickly and efficiently respond to customer needs, and completed the shield machine assembly, debugging, and acceptance tasks with quality and quantity assurance, laying a good foundation for the smooth excavation of the equipment.

It is reported that after the completion of the heating tunnel project under the Elbe River in Hamburg, Germany, the waste heat generated during the operation of the industrial zone in the southern part of Hamburg will be converted into urban heating and transported through the tunnel to the new port city in the northern part of Hamburg, replacing the existing coal-fired power plant and natural gas heating, helping to improve Hamburg's air quality and improve the living standards of local residents.
