(Summary description)Everyone knows that in recent years, my country’s urbanization process has developed rapidly. Under normal circumstances, construction in cities will be affected by factors such as dense population, heavy traffic, and numerous buildings on the ground. Various types of construction temporarily occupy land. The large area will affect traffic, cause serious pollution to the environment, and cause inconvenience to the lives and work of residents in the construction area.

Everyone knows that in recent years, my country’s urbanization process has developed rapidly. Under normal circumstances, construction in cities will be affected by factors such as dense population, heavy traffic, and numerous buildings on the ground. Various types of construction temporarily occupy land. The large area will affect traffic, cause serious pollution to the environment, and cause inconvenience to the lives and work of residents in the construction area.

Therefore, more and more urban area constructions are beginning to adopt mud-water balance pipe jacking technology to avoid excavation and laying of pipelines, which largely solves these drawbacks.
 
  Muddy water balance pipe jacking is a mechanical and automated pipe jacking construction method that cuts the soil with a full section, uses the pressure of muddy water to promote the balance of earth pressure and groundwater pressure, and uses muddy water as a medium for transporting spoil. The mud-water balance pipe jacking does not need to excavate the surface layer, but only needs to lay the pipeline directly underground, and then pass through ground structures, underground pipelines, highways, railways, rivers, etc.

On the whole, the mud-water balance pipe jacking technology is a smaller shield machine. From the aspect of shape analysis, there is a blade in front of it. With these blades, the hard soil in front of the machine head is cut, After crushing, the mud is used to send the soil to the mud sedimentation tank.
 
   Compared with artificial pipe jacking, although the construction cost of mud-water balance pipe jacking is relatively high, when the local quality is quicksand, the safety factor of mud-water balance pipe jacking is higher.
 
   Under normal circumstances, mud-water balance pipe jacking is more suitable for pipe jacking in straight line pipe jacking with a diameter of 400~1000mm, pipe jacking in silt soil layer or sandy clay soil with permeability coefficient less than 10-3m/s.
 
   Use mud-water balance pipe jacking technology for excavation-free laying of pipelines, which can cross roads, rivers, houses and other areas with deep soil covering, and can also be constructed under shallow soil covering conditions where the thickness of the pipe top is greater than the pipe diameter. Therefore, the mud-water balance pipe jacking technology is an ideal choice for laying pipelines without excavation.
