[0002] Slurry pipe jacking (SJP) has become a widely used trenchless construction technique for underground pipelines due to its high safety and efficiency. The primary equipment used in slurry pipe jacking is a pipe jacking machine. During the construction process, the rotation of the cutterhead drives the drill bit, thereby advancing the underground pipeline. This excavation process often produces large rocks. These rocks can directly enter the slurry drainage pipes, blocking them and hindering the normal progress of the construction.

[0003] The patent with announcement number CN221256783U discloses a mud-water balanced pipe jacking machine. Through the mutual cooperation between the water pipe, the nozzle and the filter screen, the nozzle arranged at the bottom of the water pipe is used to spray water to flush impurities such as mud, stones or other hard objects, separate the mud from impurities such as stones or other hard objects, and make the mud dissolve in water to become muddy water, preventing the harder agglomerated mud from clogging the slag discharge port, thereby reducing the amount of mud and stone mixture and reducing the working pressure of the crushing device. However, when the mud-water balanced pipe jacking machine is in use, it has more internal work processes and requires the use of multiple motors, which consumes more electricity and is not environmentally friendly.
