The mud-water balance pipe jacking machine is an underground tunnel excavation machine that uses mud balance pressure to push the machine head forward. Compared with the traditional shield machine, the mud-water balance pipe jacking machine performs better in the case of harsh geological conditions and high water content in the soil layer. In the past few decades, the mud-water balance pipe jacking machine has been widely used in subway, light rail, water conservancy and other fields with its advanced technology and excellent performance.

  The mud-water balance pipe jacking machine is an underground tunnel excavation machine that uses mud balance pressure to push the machine head forward. Compared with the traditional shield machine, the mud-water balance pipe jacking machine performs better in the case of harsh geological conditions and high water content in the soil layer. In the past few decades, the mud-water balance pipe jacking machine has been widely used in subway, light rail, water conservancy and other fields with its advanced technology and excellent performance.

  In the 1950s, the shield machine had just come out. Due to the limitations of technology and material conditions, there were certain problems in its engineering application. Therefore, some scientific research units began to explore new underground tunnel excavation technology. In 1955, German archaeologists invented the mud-water balanced pipe jacking technology and applied it to archaeological excavations, which laid the foundation for subsequent research and development.

  The development process of the mud-water balance pipe jacking machine is very complicated, requiring the cooperation of professionals who are proficient in machinery, water conservancy, civil engineering and other fields. Since the end of the 1960s, companies in the United States, Japan, Germany and other countries have successively put into production and continuously updated and improved technologies. Among them, companies such as Germany's Heidelberg and Japan's Mitsubishi Heavy Industries have played an important role in the development and improvement of mud-water balance pipe jacking machines.

  In the early 1980s, mud-water balanced pipe jacking technology began to be widely used in subway projects. Taking the Paris Metro as an example, the mud-water balance pipe jacking machine has played an important role in tunnel excavation, grouting and other processes due to its high efficiency and stable performance. So far, in the global subway construction, the mud-water balance pipe jacking machine is still an indispensable excavation tool.

  The mud-water balance pipe jacking machine is relatively seldom used in hydraulic engineering, but it still has its unique advantages. The mud-water balance pipe jacking machine performs well in tunnel excavation across rivers, lakes and other waters, and can avoid adverse effects on the water environment. For example, in 2011, Jinan City, Shandong Province, China excavated the 28-kilometer South-to-North Water Diversion Jinan Water Conveying Tunnel with a mud-water balance pipe jacking machine, which became a pioneering work in the history of Chinese water conservancy projects.

  At present, there is still a lot of room for development of mud-water balance pipe jacking machines in many fields such as inland tunnels and subsea tunnels. In the future, unmanned driving, intelligence, automation and other technologies will be further applied to the development and production of mud-water balance pipe jacking machines, so that their performance in engineering applications will continue to be improved.

  Generally speaking, the development process of mud-water balanced pipe jacking technology is long and tortuous, but with its good performance and wide application scenarios, it has become an important technical means in the field of underground tunnel excavation.

  The mud-water balance pipe jacking machine is a kind of mechanical equipment used for underground pipeline construction. It can dig a tunnel parallel to the ground underground, and can support, push and plant bars at the same time to realize the continuous construction of the tunnel. Its main features are:

  The system for cleaning and transporting mud can ensure the stability of mud during construction, thereby ensuring the stability of the soil layer. There is a balance system inside the machine, which can keep stable in case of soil layer collapse, so as to protect the safety of workers. The machine can carry out the work of advancing and supporting at the same time, which ensures the continuity of the construction and speeds up the construction. Reinforced mesh can be used for reinforcement to increase the bearing capacity of underground pipelines. The mud-water balance pipe jacking machine has certain adaptability and can adapt to different diameters and different types of pipeline construction.

  The construction of mud-water balance pipe jacking machine needs to follow some methods and skills to ensure the construction quality and safety. The following are some construction methods and tips: When cleaning the mud, use the appropriate mud density to prevent the liquid level from being too high or too low. Ensure the stability of the soil layer, prevent collapse and ensure the safety of workers. During the construction process, monitoring should be carried out frequently to detect problems in time and take measures. When planting bars, the appropriate method should be selected according to the soil layer. Strengthen personnel training, improve the quality of construction personnel, and maintain the safety of the construction site.

  The above are some methods and techniques for the construction of the mud-water balance pipe jacking machine. Only under the condition of reasonable use can this kind of machine equipment be better utilized and the construction of underground pipes can be successfully completed.
