Dredgers select different construction methods based on varying soil conditions during construction. Common construction methods include:
One, Excavating Hard Clay: Due to the high hardness and low moisture content of the clay, the key during excavation is to control the auger braking pressure and speed, with a thin single-layer excavation surface.
Excavating Sand and Soil: The soil is loose and coarse-grained. When dredging, the dredger must maintain moderate excavation depth, speed, and advance spacing to prevent blockages.
Three, Excavating Hard Plastic Clay: To prevent the cutting blade from getting stuck by soil lumps, it is necessary to frequently lift the blade for inspection during the operation.
Four: Excavating quicksand – The displacement and speed of the dredger can be appropriately increased.
