In the construction of the Ningbo-Zhoushan Railway in Zhejiang, the construction of the shield working shaft on the Ningbo side of the Jintang Submarine Tunnel undertaken by China Railway 14th Bureau Group has been successfully completed. This milestone achievement marks the beginning of the world's longest undersea high-speed rail tunnel, the Jintang Undersea Tunnel Shield Machine, and the construction has entered the fast lane.
The Jintang Undersea Tunnel is an important part of the Yongzhou Railway, with a total length of more than 16 kilometers, which crosses the Jintang Waterway and connects Beilun in Ningbo and Jintang in Zhoushan. As the world's longest high-speed rail undersea tunnel, it is extremely difficult to construct and needs to overcome complex geological conditions and environmental factors on the seabed. In order to achieve this goal, China Railway 14th Bureau Group adopted the shield method for construction, which is a safe, efficient and environmentally friendly tunnel construction method.
The shield working shaft is one of the key projects in the construction of the shield tunnel, and its construction quality is directly related to the starting of the shield machine and the safety of the tunnel. During the construction process, China Railway 14th Bureau Group operated in strict accordance with the design requirements and construction specifications to ensure the stability and safety of the shield working shaft. At the same time, in order to cope with possible risks and challenges, the Group has also formulated detailed emergency plans and technical measures to ensure the smooth progress of construction.
With the successful completion of the shield shaft, the construction of the Jintang Submarine Tunnel has entered the fast lane. In the next work, China Railway 14th Bureau Group will continue to give full play to its professional advantages and experience, strengthen technical research and safety management, and ensure the quality and safety of tunnel construction. At the same time, the group will also actively cooperate with relevant units and departments to do a good job in environmental protection and monitoring to ensure the sustainable development of the project.
The construction of the Jintang Cross Harbour Tunnel is an arduous and complex project, which requires the joint efforts and support of all parties. The construction and construction of China Railway 14th Bureau Group provides a solid foundation and guarantee for the construction of the tunnel. It is believed that with the joint efforts of all parties, the Jintang Undersea Tunnel will be successfully completed and make important contributions to the construction and development of the Ningbo-Zhoushan railway.
With the completion of the shield shaft, China Railway 14th Bureau Group will continue to assume more responsibilities and missions and contribute to the development of China's infrastructure construction. As a well-known construction enterprise in China, China Railway 14th Bureau Group has rich experience and professional technical team, which can cope with the construction needs of various complex projects. In the future, the Group will continue to uphold the enterprise spirit of "integrity, innovation, excellence, and win-win", actively participate in infrastructure construction at home and abroad, and make greater contributions to promoting the development of the national economy and social progress.
In the construction of the Jintang Undersea Tunnel, China Railway 14th Bureau Group has demonstrated excellent technical strength and efficient teamwork ability. In the face of complex geological conditions and environmental factors on the seabed, the Group has overcome one technical difficulty after another through continuous technological innovation and practical exploration, ensuring the quality and safety of tunnel construction. This spirit of courage to innovate and challenge is not only reflected in the construction of the Jintang Undersea Tunnel, but also the source of power for China Railway 14th Bureau Group to continuously pursue excellence and create value.
In addition, China Railway 14th Bureau Group also pays attention to environmental protection and sustainable development during the construction process. By adopting a series of effective measures and technical means, the impact of construction on the surrounding environment is minimized, and the green, environmental protection and eco-friendly characteristics of the project are ensured. This environmental awareness and sustainable development concept not only meets the needs of the country and society, but also is the inevitable choice for China Railway 14th Bureau Group to achieve long-term development.
In conclusion, the construction of the Jintang Undersea Tunnel is a milestone project, and its completion will lay a solid foundation for the construction and development of the Ningbo-Zhoushan railway. As the contractor and the main body of construction, China Railway 14th Bureau Group has played an important role and contribution in the construction of the project. It is believed that in the future, China Railway 14th Bureau Group will continue to give full play to its own advantages and professional expertise.
