7. The pipe replacement system of claim 1, further comprising:
a display;
the visual camera, through the repeater with display electric connection, the visual camera set up in the jacking device, the visual camera is used for observing in real time the replacement process of the broken condition of circular cutting drill bit subassembly and/or new pipe, the position that is used for connecting the visual camera of jacking device with circular cutting drill bit subassembly can take place relative rotation.
8. The pipe replacement system of claim 7, further comprising:
the radar antenna is used for detecting the upper geological layer part of the pipeline on the geological layer with abundant underground water so as to know whether collapse and other conditions exist above the pipeline;
the sonar probe detects the upper geological layer part of the pipeline positioned on the waterless geological layer to know whether collapse and other conditions exist above the pipeline;
the radar antenna and the sonar probe are arranged on the jacking device, and the position of the jacking device, which is used for connecting the radar antenna and the sonar probe, and the circular cutting drill bit component can rotate relatively.
9. The pipe replacement system of any one of claims 1-8, further comprising:
the centralizer is sleeved on the drill rod, and the peripheral side of the centralizer is abutted to the inner surface of the old pipe.
10. A method of pipe replacement using the pipe replacement system of any one of claims 1-9, comprising:
penetrating the drill rod into the old pipe from a first observation well communicated with one end of the old pipe, and penetrating the drill rod to a second observation well communicated with the other end of the old pipe;
putting the circular cutting drill bit assembly into a second observation well penetrating through the drill rod, connecting one end of the circular cutting drill bit assembly to the end part of the drill rod penetrating to the second observation well, connecting one end of a new pipe to the other end of the circular cutting drill bit assembly, and connecting the other end of the new pipe to the jacking device;
by pulling the drill rod, the drill rod is made to move towards one end of the old pipe, which is communicated with the first observation well, by pulling the circular cutting drill bit assembly, so that the circular cutting drill bit assembly breaks the old pipe, and the jacking device is made to move towards the circular cutting drill bit assembly by pushing the new pipe so as to drive the new pipe to occupy the position of the old pipe before moving.
