8. The method of claim 6, wherein the inner diameter of the pipe is measured by an internal support distance detecting switch on the inner support block.
9. An intelligent pipe laying method as claimed in claim 6, wherein the inner support blocks are sensed by inner support pressure sensors on the outside of the inner support blocks to detect whether they are in sufficient contact with the inside arms of the pipe.
10. An intelligent pipelaying method as claimed in claim 1, wherein the gap between abutting ends of the pipeline is sealed by a sealing system after the pipeline has reached the abutting position; the sealing system comprises a sealing hydraulic cylinder, a sealing hydraulic motor, a sealing driving shaft, a sealing liquid spray gun, a sealing liquid storage cavity and a sealing positioning detector;
a seal positioning detector at the front end of the seal driving shaft detects the position of an end gap between adjacent butted pipelines along with the gradual extension of the seal hydraulic cylinder; and when the sealing positioning detector detects the position of the butt joint gap, the sealing hydraulic cylinder stops extending, the sealing hydraulic spray gun is opened, and the end gap position between the butt joint pipelines is sprayed with sealing hydraulic in a rotating mode.
