1. The start of the construction:
Before the dredger starts the construction, first organize the personnel to the posts, start the excitement boat to the designated construction area to measure the water depth and observe the terrain.

When the water depth and construction conditions are available, the dredger begins to prepare for positioning.
When the dredger is not positioned to the designated construction site, the positioning pile must be erected first. To erect the positioning pile, you must find a deeper water area that can meet the water area operation of the positioning pile erection. Use the service motor boat to tow the dredger to the surveyed place. The water area is prepared to erect piles.
First start the reserve power generation price group, start the hydraulic system emergency hydraulic pump to make the hydraulic system work normally, first release the left and right traverse cable from the front traverse pulley through the hull under the hull to reverse to the root of the positioning pile, fixed. Then the bridge winch puts the bridge shrimp paste into the water.
After starting the traverse winch, slowly let it go so that the positioning pile is slowly erected. The vertical left locating piles are moved to the left and horizontally by the winch, and the vertical right locating piles are moved to the right and the winch is retracted. Pay attention to safety during pile erection. The wire rope on the positioning pile lifting cylinder is connected well. Use hydraulic cylinders to lift the positioning pile and adjust it to the required height of the construction area.
Start to move the dredger to the construction area, put down the positioning piles, and insert the positioning piles into the mud to fix the dredger.
Start the engine normally, and move the winch left and right to throw out the positioning anchor.
2. Construction and production:

The next step after the dredger starts to move is construction and production. The conditions for construction and production are that the wind cannot exceed level six, the flow current cannot be too large, and the places with tides should also be paid attention to.
All conditions that meet the construction conditions can enter normal production and working conditions. Pay attention to the lifting height of the positioning pile during production.
Do not allow two piles to be inserted into the sand at the same time. Pay attention to the operating conditions of the engine and hydraulic system. Observe the various instruments, there are sailing ships pay attention to the movements of the sailing ships.
3. Combining work:
the dredger can stop production after the completion of this phase of the project.
Before stopping production, the dredger's pipeline must be flushed and the pipeline can be dismantled and piled up when all the pipelines are clear.
