In winter, it is a good season for Jiantang fish farming and fish pond dredging. The following describes the selection methods for dredging and dredging machinery for fish ponds: 1. For excavation of fresh fish ponds, bulldozers should be used. The machine is convenient and efficient. About 500 to 500 earths can be completed per bulldozer each 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. 2. Excavation should be expanded to bring water ponds and fish ponds should be selected. The unit can simultaneously complete the five processes of digging, loading, transporting, unloading and arranging. 3, fish pond dredging, should use hydraulic pond digging unit. 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 ship can also be used. The ship can use suffocating suction and pipeline dredging to ensure the continuous operation of underwater dredging of fish ponds and can directly transport sludge to fish ponds 200 meters away. In places, the mud concentration can reach 89.11%. 4. 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 lift of the pump. The distance of the water gun from the impact surface is generally not more than 4 meters. The flushing volume is 3 to 5 times of the mud volume of the pond. The suction concentration of the mud pump is 60%-80%, the diameter of mud blocks and impurities should be less than 50mm, and the distance of transport mud should not exceed 200m. 5. During the operation, 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.
