Trenchless drilling typically uses a horizontal pilot drill. The working principle of the horizontal guide drilling machine is as follows: during construction, according to the designed arc drilling track, a drilling machine capable of drilling from the earth surface is adopted to drill a guide hole which is approximately horizontal, then a large-diameter expanding bit and a to-be-laid working pipeline with the diameter smaller than that of the expanding bit are replaced after the guide bit, then reverse expanding is carried out, the to-be-laid pipeline is pulled back into the drill hole, and when all drill rods are pulled back, the pipe laying work is completed at the same time.
In a specific drilling process, a drill frame of the guide drilling machine is obliquely arranged at a small angle relative to the ground, and a power head on the drill frame drives a drill bit to rotate and feed so that the drill bit performs drilling operation. During the feeding process, as the drilling length increases, the drill rods need to be inserted one by one.

Therefore, the drill rod needs to be lifted up and placed on the manipulator in an inclined mode, and the labor intensity of workers is undoubtedly increased.
