Bulldozers are common earth-moving machinery and play an important role in construction. What are the common construction methods of bulldozers? Common bulldozing construction methods of bulldozers mainly include downhill bulldozing, batch-concentrated one-time pushing, parallel bulldozing, trench bulldozing, angled bulldozing and other construction methods.
1. Downhill bulldozing
It can increase the bulldozer’s shoveling depth and the amount of soil transported, improve production efficiency, and can be used when bulldozing mounds and backfilling trenches.
2. Batch-concentrated, one-time pushing method
In harder soil, the bulldozer’s cutting depth is small, and the amount of soil shoveled at one time is not much. It can be concentrated in batches and then pushed to the unloading area in batches. This method can increase the number of blade pushes, shorten transportation time, and improve production efficiency.
3. Parallel bulldozing method
In the construction of a large area of leveling site, two or three bulldozers are used to push in parallel. Generally, the amount of bulldozing of each bulldozer can be increased by 20%. When bulldozing in parallel, the distance between the shovels is 15 to 30 cm. The number of parallel bulldozers should not exceed four.
4. Trench bulldozer method
It is to bulldoze along the original trench where the bulldozer was bulldozed for the first time. The soil ridge formed by the previous bulldozer can prevent the soil from being lost, thereby increasing the amount of bulldozers. This method can be used in conjunction with the batch concentration and one-time push method.
5. Angle bulldozer method
The shovel is installed obliquely on the bracket, and the bulldozer forms a certain angle in the horizontal direction to perform bulldozing. Generally, this method can be used when the trench is backfilled and there is no room for reversing.
