On December 26, the welding of B pipe of the Yangtze River shield pipeline installation project of the east line of China and Russia undertaken by the fourth company of the pipeline bureau broke through 18 kilometers, and the total number of pipeline welds in the tunnel of the project has exceeded 12 kilometers. After the completion of the project, it will become the pipeline installation project in the world's oil and gas field with the longest distance, deepest burial depth and most complex construction conditions.
The Yangtze River shield pipeline installation project is located between Haimen Economic and Technological Development Zone, Nantong City, Jiangsu Province and Changshu Economic and Technological Development Zone, which is the "throat" project of the East Line of China and Russia. After the pipeline installation is completed, the foam concrete is filled under the tunnel, and the daily inspection device of the robot is reserved above the tunnel.
In view of the problems such as the increasingly limited construction space of the project, the project department went deep into the site to focus on "consultation", solved the problems encountered in on-site production in a timely manner, and tailored special equipment, facilities and tools in combination with the working conditions in the tunnel. The project department analyzes the unsafe state and the impact of environmental factors in the whole process of project implementation based on the environment, input equipment and technical scheme of the construction area, sorts out the risk points, and formulates countermeasures to ensure the smooth progress of the construction.
