Abstract

PURPOSE:To treat deposit soil without soiling the whole of dam by a method in which water pumped up with soil is separated from soil in a solid-liquid separator tank and converted into water jet in an injector to make jet excavation. CONSTITUTION:Deposit soil on the bottom of dam, etc., is pumped up by a pump 4 and supplied through a suction pipe 6 and a water inlet section 3 into a solid-liquid separating tank 2. Water pressure acts on the water of a purified water pipe 6 from the purified water takeout section 5 of the tank 2, and purified water is jetted from an injector connected to the tip of the pipe 6 to excavate soil.
