Measures for Dredger to Deal with Different Soil Properties
1.Excavation of hard clay
The hardness of the clay is high and the water content is low. During the operation of the dredger, the key point is to control the braking pressure and speed of the cutter, and the single-layer mud excavation surface should be thin.
2. Sand excavation
The sandy soil is relatively loose and coarse. The thickness, speed and forward step of the dredger during excavation shall not be too large to prevent blockage (d) ǔ sè)。
3. Excavation of hard plastic clay
In order to prevent the earth block from sticking to the reamer, the reamer should be lifted frequently for patrol inspection during the working process.
4. Excavation of quicksand
The moving distance and speed of the dredger can be appropriately increased.
Before starting the dredger, inspect the machine to see whether the machine system is normal and whether the oil is sufficient. Then start the front and rear diesel engines of the dredger to make the machine operate. During dredging, pay attention to the movement of the machine boom, and flexibly adjust the direction of the boom according to the amount of sediment. If the dredging is hard, move the dredger back and forth. If there are large stones and other hard things, avoid them. So as not to damage the dredger. When the dredger is not in use, put it in a safe place and tie it up to prevent it from being washed away by water. Also take good care to avoid theft.
