The construction method of ground arrow type micro-pipe jacking according to claim 8, characterized in that: The following steps are involved: Said S1: placing the guide rod (61) on the top of the pipe rack (5), pushing the guide rod (61) by means of the pipe jacking device (4), and after the guide rod (61) enters the soil, connecting the guide rod (61) with the guide tube (62), continuing the pipe jacking operation, and repeating the above steps until the channel pipe jacking operation is completed; S2: During the pipe jacking operation of the guide rod (61), the squeezing groove (613) is used to allow soil to fall into the inner cavity of the hollow pipe (611) through the squeezing groove (613), and by collecting part of the soil, the squeezing of the hollow pipe (611) by the soil is reduced; S3: When the guide rod (61) moves in the soil, the friction force between the soil and the friction belt (6163) is utilized to cause the friction belt (6163) to drive the shaft column (6162) to rotate, and the gear belt (6167) drives the eccentric shaft (6166) so that the eccentric shaft (6166) drives the compaction guide assembly (616) to vibrate, thereby causing the compaction guide assembly (616) to drive the guide rod (61) to vibrate, so that the guide rod (61) can compact the channel in the soil; S4: The hydraulic telescopic rod (6165) drives the mounting frame (6161) to rotate with the end of the compaction guide assembly (616) close to the cone head (614) as the axis, so that the compaction guide assembly (616) rotates toward the outside of the hollow tube (611), thereby pushing the hollow tube (611) and guiding the direction of the hollow tube (611); S5: At the same time, the sealing rotating plate (618) is pushed by the hydraulic telescopic rod three (619) to rotate the sealing rotating plate (618) toward the outer wall of the hollow tube (611), and a V-plate (617) is provided in the middle of the two sets of sealing rotating plates (618), so that the soil located in the inner cavity of the hollow tube (611) is guided by the V-plate (617), so that the soil is discharged through the opening on the side driven by the hydraulic telescopic rod three (619) to rotate the sealing rotating plate (618), and then the soil fills one side of the hollow tube (611), thereby squeezing the hollow tube (611) and further guiding the direction of the guide rod (61).
