The main ways of bulldozing include the following:
Downhill bulldozing: This method is used when bulldozing hills or backfilling trenches. It can increase the depth of bulldozers and the amount of soil transported, and improve production efficiency.
Batch concentration and one-time push method: In harder soil, the bulldozer has a smaller cutting depth and does not shovel much soil at a time. The soil can be concentrated in batches and then pushed to the unloading area in batches. This method can shorten transportation time and improve production efficiency.
Parallel bulldozing: In the construction of a large area of leveling site, two or three bulldozers can be used for parallel bulldozing. This method can reduce soil loss and increase the amount of bulldozing. Usually, the amount of bulldozing per bulldozer can be increased by 20%. When bulldozing in parallel, the distance between the blades is generally 15 to 30 cm, and the number of parallel units should not exceed four.
Trough bulldozing method: bulldozing along the original trench where the bulldozer was pushed for the first time. The soil ridge formed by the previous bulldozing can prevent the soil from being lost, thereby increasing the amount of bulldozing. This method can be used in combination with the batch concentration and one-time push method.
Angled bulldozing method: The blade is installed obliquely on the bracket, and bulldozing is performed at a certain angle to the horizontal axis of the bulldozer. This method can improve the flexibility and adaptability of the bulldozer.
These methods can be selected and used according to the specific construction environment and needs to improve construction efficiency and project quality.
