The invention discloses an intelligent multi-stage riverway desilting method. The bottom terrain and silt layer thickness distribution information of a riverway is measured through a sonar test set; during sonar detection, sonar detection is carried out at two kinds of different frequencies at the same time, one frequency is matched with detection of a river bottom silt layer, and the other frequency is matched with detection of a riverbed bottom original structure of a non-silt layer. One measured area of the riverway is divided into multiple small areas, a calculation model is set up, and the riverway silt deposition thickness is estimated. Detected large solid garbage is subjected to targeted excavation and clearing though a crane and an excavator of corresponding types. For silt severely afflicted area reach dikes and cutoff riveways tested by a sonar system, riverway river water between dams is exhausted to the rated mixing depth of prepared stirring equipment, and then a high-pressure water gun is adopted for washing away river bottom silt. An amphibious backacting shovel type desilting machine and a chain bucket type bucket-ladder dredger are put into service with targets toachieve desilting step by step. The desilting method is high in desilting efficiency and good in effect.
本发明公布了一种智能化多级河道清淤法，利用声纳测试仪测量河道底部地形和淤泥层厚度分布信息，在声纳检测时，同时以两种不相同的频率进行，其中一种频率匹配河底淤泥层的检测，另一种频率匹配非淤泥层的河床底部原始结构的检测。将河道被测量的其中一个区域分成若干个小块区域，建立计算模型，估算河道污泥沉积厚度。将检测到的大型固体垃圾物采用相应型号的吊车、挖掘机进行目的性挖掘、清理。对声呐系统测试的淤泥重灾区河段筑堤、截断河道，将堤坝之间的河道河水排至预备搅拌设备的额定搅拌深度，然后采用高压水枪冲刷河底淤泥。有目标地投入两栖反铲式清淤机、链斗式挖泥船逐步清淤。本清淤方法清淤效率高、效果好。
