S3, pushing the frame body 1 to an initial position after tamping, adjusting a stirring range of the stirring mechanism 2 to enable the stirring mechanism 2 to stir the rest earthwork far from the pipe trench, adjusting the sieve hopper 31 to be close to a vertical state through the turnover piece 32, preventing the sieve hopper 31 from intercepting large-particle stones or hard soil blocks, and pushing the frame body 1 along the length direction of the pipe trench again to push the rest earthwork to the pipe trench;
S4, in the process of pushing earthwork to a pipe ditch, the receiving tray 41 is taken down from the first rotating shaft 311 and is supported by the supporting mechanism 5, at the moment, the receiving tray 41 is in an inclined state, one end of the receiving tray 41, which is close to the sieve hopper 31, is the lowest end, and large-particle stones or hard soil blocks led into the receiving tray 41 from the sieve hopper 31 can enter the pipe ditch together with the earthwork;
s5, compacting earthwork entering the pipe ditch through the compactor every time the specified depth is backfilled.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
