Reasonable measures for Dredger to deal with different soil properties
1. Excavation of hard clay
The clay has high hardness and low water content. 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 excavation thickness, speed and forward step of the dredger shall not be too large during excavation to prevent blockage
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. If the dredging is hard, move the dredger back and forth. If there are large stones and other hard things, avoid them to avoid damaging the dredger.
