Bulldozer filling pit
The main difficulty is how to make the area close to the ground, push the soil into the pit, and use the shape of the pit to generate the corresponding pushed soil. Similar to the work of pre-embedded pipelines, the amount of soil in the position occupied by the pipeline needs to be deducted, and the amount of soil remains absolutely conserved. With this function, bulldozing, excavation and landfill operations can be greatly enriched.
