The mud-water balance pipe jacking machine is a professional underground tunnel construction equipment and an indispensable part of modern urban construction. So, what is the process principle of the mud-water balance pipe jacking machine? Let's explore it together.

　　It is a machine for underground tunnel construction using mud, shield machine, segment and other equipment. The basic principle of the mud-water balance pipe jacking machine is to use a certain amount of mud fluid to maintain the balance of the excavation face, avoid the subsidence of the strata and segments, and also play a role in supporting the segments. At the same time of excavation, the mud liquid can transport the excavated soil and then carry out the functions of stratum support and hydraulic support.

　　The working process of the mud-water balance pipe jacking machine is generally divided into three steps: excavation, injection of segments and support.

　　Excavation is the first step in the work of the mud-water balance pipe jacking machine. It uses hollow pipes and cutting heads to push through geological strata such as soil and rocks, and at the same time, transports mud liquid to ensure that the excavation face remains in a balanced state. The pressure injection segment is the second step of the mud-water balance pipe jacking machine. The segment is hoisted from the top to the jacking machine for pressure injection; due to mud deposition and self-gravity, after the segment drops to the predetermined position, the next piece The segments are hoisted to the pusher for pressure injection. This reciprocating cycle, until the pressure injection to the next pumping station or well out of the hole. As an important step in the work of mud-water balance pipe jacking machine, support is usually adopted in two ways: segment outer slurry injection support and support ring and ring upper component support.

　　It has many remarkable features: it works under the geological conditions of bending and strong toughness. The equipment can improve the construction speed and quality of underground construction. Control parameters such as mud pressure, viscosity and construction weight coefficient to ensure the construction quality of tunnel engineering. It can reduce the excavation, up-transportation and discharge of earthwork, and reduce the pollution on the construction site.

　　The mud-water balance pipe jacking machine is suitable for sedimentary rock and semi-hard rock formations with a slope of less than 35 degrees. It is generally used in large-diameter urban tunnel construction, rail transit, water conservancy and hydropower and other industries. It can improve the efficiency of construction, shorten the construction period, and protect the environment of the construction site.

　　With the rapid development of urban construction, mud-water balance pipe jacking machines are more and more widely used in urban construction. In urban construction, some underground structures such as drainage pipes, gas pipes, etc. have become an inevitable trend to be constructed underground, and the advanced technology of mud-water balance pipe jacking machines provides strong support for these projects. Therefore, the application of mud-water balance pipe jacking machine in urban construction will become more and more important.

　　To sum up, its technological principle is to use mud fluid to maintain the balance of excavation work and realize underground tunnel construction. It has a wide range of applications and has a great role in promoting urban construction.
