The invention discloses a hydraulic engineering desilting device and a desilting method thereof, and relates to the field of hydraulic engineering. According to the hydraulic engineering desilting device and the desilting method thereof, the hydraulic engineering desilting device comprises a floating type air bag sewage suction boat and a sludge pump, a sludge pipeline and a drainage pipeline are installed between the floating type air bag sewage suction boat and a synchronous carrier, a dewatering box is installed at the top of the synchronous carrier, and an injection pipe, a stirring roller and a water power driver are installed at the bottom of the floating type air bag sewage suction boat. According to the hydraulic engineering desilting device and the desilting method thereof, sludge pumped out of a riverbed is dewatered through the dewatering box and returned to the injection pipe, the suction position is injected through the injection pipe, meanwhile, water drives the stirring roller to stir the sludge when passing through the injection pipe, excessive loss of water in the riverbed is avoided, meanwhile, the returned water softens and dilutes the suction position, and the desilting efficiency is improved. And the situation that sludge is too sticky and cannot be sucked after water in the riverbed is discharged outwards is avoided.

本发明公开一种水利工程清淤装置及其清淤方法，涉及水利工程领域。该水利工程清淤装置及其清淤方法，包括漂浮式气囊吸污船和污泥泵，漂浮式气囊吸污船与同步载具之间安装有污泥管道和排水管道，同步载具的顶部安装有脱水箱，漂浮式气囊吸污船的底部安装有喷射管、翻搅辊和水动力驱动器。该水利工程清淤装置及其清淤方法，通过脱水箱将抽离河床的淤泥进行脱水，返回至喷射管，通过喷射管对抽吸位置进行喷射，同时水经过喷射管时带动翻搅辊对淤泥进行搅拌，避免河床中水过分流失，同时返回水对于抽吸位进行软化稀释，避免河床中的水被向外排除后淤泥过于黏稠无法抽吸。
