In the process of dredging and excavation of fish ponds, different types of machinery should be used. For excavation of fresh fish ponds, bulldozers should be used. The machine is convenient and efficient. Each bulldozer can complete 300 to 500 earthworks per day. The excavation operation point should be started from the ground. Pushing the earth into the perimeter of the surrounding slope will build a dam, which can play a role in compacting the bottom of the pond and the slope and preventing leakage. Excavation and expansion of fish ponds with water, should use hydraulic pond digging unit. The unit can simultaneously complete the five processes of digging, loading, transporting, unloading and arranging. For dredging of fish ponds, hydraulic digging pond units should be used. The unit can suck up sludge and carry out operations such as long-distance transport, composting, and land reclamation. In addition, a multi-functional dredging motor boat can also be used. The ship can use suffocating suction and pipeline dredging to ensure the continuous operation of underwater dredging of fish ponds. Use digging pond dredging machinery, according to different soil quality, choose the appropriate flushing pressure and impact method. If the mud or mud at the bottom of the pond is removed, the flushing pressure is generally 3.5 kg/cm2; if the original loess is removed, 5 kg/cm2 is needed; if the compacted clay or original fine sand is removed, 7.5 kg/cm2 is required. The flushing pressure can be estimated according to the pump lift. The distance from the water gun to the impact surface is generally not more than 4 meters. The flushing volume is 3 to 5 times of the amount of mud in the pond. The suction concentration of the mud pump is 60% to 80%, the diameter of the mud blocks and impurities should be less than 50 mm, and the distance of the transport mud should not exceed 200 meters. During operations, the crew should be regularly cleaned, overhauled, refueled, and replaced with damaged parts. Schedule electromechanical equipment and leak safety checks. Pump filter mouth should be added filter cover, motor should be covered with shell protection.
