Construction method:
According to the common construction conditions of sewage pipe network and the advantages and disadvantages of the existing trenchless process, our company has developed a simple pipe jacking process

It not only has the advantages of directional drilling: wide geological adaptability, strong obstacle handling capacity and small secondary disasters, but also has the advantages of accurate pipe jacking elevation control
The process is between directional drilling process and mud water balance
At the same time, with the flexible sealing and self-locking interface, polyethylene is wound around the solid wall drainage pipe (also known as short pipe), the traditional pipeline is pulled back to the jacking process, the pipe joint is installed underground at the end, the reused drill pipe passes through the center of the pipeline, and the pipeline is jacked at the tail end of the pipeline
The excavation head is responsible for the excavation torque and head-on resistance, and the residual force of the equipment is transmitted to the pipe body through the transfer device and dowel bar behind the head to achieve the purpose of jacking
The digging head and pipe are not locked to achieve the mud water balance function
The pipe only needs to bear the jacking friction resistance in the jacking process

In the jacking stage, mud is allowed to enter the pipeline to achieve the effect of counterweight resistance reduction
The required final hole diameter is close to the outer diameter of the pipeline, and there is basically no annular gap
The construction adopts the process of directional drilling after well construction, back expansion excavation and top pipe pulling
Under the condition that the well hole elevation is controlled and the steel drill pipe is straightened and penetrated, the pipeline elevation control is quite accurate

Our company cooperates with municipal first-class units, has a professional construction team, and has accumulated rich technical experience in jacking pipe construction, which can well meet the needs of customers and serve the trenchless construction method industry
