Abstract

PURPOSE: To simplify the treatment by mixing alkaline or acid salt such as CaCl2 in sediment excavated and discharged by mixing a high absorbing resin and by performing peptization in a short time thereby releasing moisture due to water absorption. CONSTITUTION: Gelation is performed by supplying a high water absorbing resin from a supply pipe 28 to excavated sediment taken in an earth pressure chamber 16 through a cutter header 12 and excavated sediment A is created. Next, the sediment A is carried to the rear of a belt conveyor 36 from a screw conveyor 24 and when it is transferred to a muck lorry 38, salt B such as liquid or powdery CaCl2 is mixed. And a gel bridge structure of sediment A is shrunk and moisture taken in the bridge structure is released in a short time. Thus, dense compaction becomes possible and the transport and disposal thereafter can be carried out simply.
