the method comprises the following steps: firstly, placing a chassis (2) arranged on two sides of an excavated ditch, moving a sliding block to enable a supporting plate (601) to move to a set position, rotating the supporting plate (601) to enable the supporting plate to deflect, starting a first motor (501), and driving a first transverse plate to rotate by the first motor (501) until the pipeline clamping direction of a clamping claw (521) is consistent with the pipeline conveying direction of the supporting plate (601);

step two: an operator places one end of a pipeline between two conveyer belts (604) and starts conveyer belt (604), conveyer belt (604) drive buffer suction cup (606) and move, and then drive the pipeline and move, the central point that makes the pipeline passes between two gripper jaws (521) and is located the position that gripper jaw (521) snatched until the pipeline, start corresponding electric putter one (513) or electric putter two (514) that set up, and then make two gripper jaws (521) take place to deflect, and then make buffer plate (518) stabilize the centre gripping to the pipeline, start motor one (501) once more, and then make gripper jaw (521) drive the pipeline and deflect until the angle that the ditch was transferred to the pipeline of being convenient for.

Step three: and starting the electric push rod five (523), wherein the electric push rod five (523) drives the transverse plate two (505) and the pipeline at the bottom of the transverse plate two (505) to descend until the pipeline descends to the bottom of the inner wall of the ditch, and then starting the electric push rod one (513) or the electric push rod two (514), so that the sliding cylinder (515) is driven to move upwards and drive the clamping claws (521) to deflect through the connecting rods (522) until the clamping claws (521) release the clamping on the pipeline, and the accurate placement of the pipeline is realized.
