In the winter season, it is a good season for fish pond dredging and fish ponds in Jiantang. The following describes the selection methods for dredging machinery for fish ponds:
1. 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 ship can also be used. The ship can be suffocated to ensure the continuous operation of dredging, and the mud can be directly transported to a place 200 meters away from the fish pond. The mud concentration can reach over 90%. .
2. Excavation and expansion of fish ponds with water should be selected hydraulic units. The unit can complete the process of digging, loading, transporting, unloading and arranging at the same time.
3. New excavation of waterless ponds, bulldozers should be used. About 500 to 500 earths can be completed per bulldozer 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.
Precautions:
1 When using the digging pond dredging machinery, according to different soil quality, select the appropriate flushing pressure and impact method. If the bottom mud or mud is removed, the flushing pressure is generally 3.5 kg/cm2; if the original loess is removed, 5 kg/cm2 is required; if the compacted clay or original fine sand is removed, 7.5 kg/cm2 is required. Water gun from the impact surface distance, a
Generally no more than 4 meters. The suction concentration of the mud pump is 60% to 80%, and the diameter of mud blocks and impurities should be less than 50mm.
2 During operation, the unit should be regularly cleaned, overhauled, refueled, and replaced with damaged parts. Conduct safety inspections on electromechanical equipment. Pump filter mouth should be added filter cover, motor should be covered with shell protection.
