How to Excavate Canal with Cutter Suction Dredger?
Yongsheng Dredging Equipment Co., Ltd. is an enterprise specializing in the research, design and production of dredgers, sand dredgers, gold dredgers, sand pumping boats, desilting equipment, desilting and grass cutting boats, beneficiation equipment, crushing and sand making equipment. Today, let's take you to learn how cutter suction dredgers excavate canals.
When the dredger starts dredging, put the reamer head in the middle of the canal, and then put the reamer head down to start excavation. When the cutter head is excavated to the specified depth, the dredger is positioned with positioning piles, and the cutter arm is over operated to both sides to flatten the soil on both sides. Repeat the operation repeatedly until the operation area is excavated to the specified depth and width, and then push the cutter suction dredger forward to carry out the dredging operation in the next area.
When the cutter suction dredger excavates the canal, it is necessary to determine the excavation depth and width first, and then move the dredger to the excavation area. After driving to the operation area, put down the positioning pile for positioning, start the engine for excavation, and excavate from the middle to both sides according to the excavation sequence.
If necessary, report the dredger's coordinates (longitude and latitude), anchors, pipelines, etc.
When excavating the excavated trench adjacent to it, if it exceeds the edge of the design trench by 2-3m, the reason shall be found. When excavating to the lower layer, pay attention to the lowering depth of the reamer of the cutter suction dredger. The excavation and suction shall be sufficient and the ditch bottom shall be flat. If necessary, a certain amount of back siltation shall be reserved and measured in time. The measurement data shall be accurate.
The above is the method of excavating the canal with cutter suction dredger. When the depth or width of the canal to be excavated is long, it can be carried out in sections. It must not be excavated in place at one time, which will cause great damage to the cutter head during desilting.
