At present, a great amount of sludge is accumulated in ponds or river channels due to various reasons, so that the problem of the accumulation of the sludge is increasingly prominent, and the effective water level is inevitably reduced and the water ecological environment is influenced by reporting that the sludge is excessively accumulated through related information. According to investigation, the sediment of the pond sediment is increased year by the thickness of 6-8 cm due to the deposition of residual baits, fish excrement and the like, the thickness of 91.9 percent of the sediment is more than 40cm, and the thickness of 47.4 percent of the sediment is 60-80 cm; tests prove that the residual bait and the like deposited on the bottom of the pool have obvious influence on the pool water and the bottom material, the pH value of the pool water is reduced, and the content of ammonia nitrogen, nitrite and sulfide is increased. Treatment of the sludge is required. At present, three technical structures for dredging the pond are provided, one is to drain water in the pond and work by an excavator or a bulldozer; the second is to use manual digging or water gun impact and slurry pump pumping; the third is underwater operation with simple implements.
The existing method for impacting sludge by using a water gun generally comprises the steps of segmenting a river channel and building a cofferdam, and draining accumulated water in the river channel to a sufficient stirring depth instead of completely draining the accumulated water in the river channel. The construction mode adopts a high-pressure water gun to scour and destroy river bottom sludge, and then adopts a slurry pump to pump and discharge the slurry to a sludge centralized treatment area. The muck which cannot be scoured and damaged at the river bottom can be lifted to a muck truck for outward transportation in a mode of manual cleaning or excavation by a long-arm excavator. The advantage that the squirt strikes lies in that the desilting is thorough, and is easy and simple to handle, is convenient for pass bridge and other river course barriers, uses the pipeline to carry mud also can avoid the secondary pollution on the way of transporting, reduces the interference to the resident of river course both sides. The existing water gun impact method is generally controlled manually, the impact range is effective, and in the process of flushing sludge, the sludge is loosened after being flushed by a high-pressure water gun, so that the personnel standing position is easily sunk, and certain potential safety hazards exist.
