In addition, during the split launching stage, a tunneling task of more than 100 meters needs to be completed. If the supporting equipment is arranged at the wellhead or on the ground as in the traditional launching technology, a series of problems will occur, resulting in difficult guarantee of construction quality and accelerated damage speed of the tail seal brushes.

Moreover, the input mud can also cool and lubricate the shield machine, reducing the wear of the shield machine. The outlet connecting pipe 310 and the inlet connecting pipe 320 of the slurry discharge pump 300 are respectively connected with a first transition hose 330 and a second transition hose 340, thus avoiding the hard slurry discharge pipe from being broken by the large-amplitude vibration during the operation of the slurry discharge pump; this device effectively ensures the stable operation of the shield machine and improves the construction quality.
