Ensure that the connection of each component is firm and check the operating status and safety of the equipment. The staff moves the earth filling and tamping device to the filling position by pulling the traction device 3. The earth material is put into the crushing and feeding device 4 through the feed hopper 402. The rotating blades 905 in the crushing assembly 9 crush the earth material into the required size. The dust and impurities generated during the crushing process are sucked into the dust hood 502. The fan 503 generates negative pressure and sends the dust and impurities into the dust collecting solidifier 504. The dust collecting solidifier 504 collects and solidifies the dust and impurities, and the clean air is discharged. The put-in material is rolled by the roller 601 to make it flat. The tamping hammer 7010 makes vertical reciprocating motion in the guide sleeve 709 through the guide shaft 705. The tamping hammer 7010 tamps the earth through the tamping plate 7011 to increase the density and stability of the earth. The staff pulls the device until all the pipe pits are filled. After the work is completed, the various parts are cleaned to ensure that the device is clean, and necessary maintenance and inspection are carried out to ensure normal operation the next time it is used.
