To simultaneously carry out reclamation and the improvement of ground by supplying filling fluid to a sediment in a course of transportation made through a sediment transporting device, and stirring and mixing them.
Earth and sand are transported to a disposal site such as a reclamation site as they are improved in a sediment transporting device, where a charge port 1 and a discharge port 2 are provided in the upper part of a housing H, and a transporting pipe Tp is connected to the discharge port 2. A crusher D is provided in the housing H, and a pressure feed device T for pressure feeding the sediment crushed by the crusher D through the discharge port 2 and the transporting pipe Tp to the disposal site is provided. A prescribed quantity of fluid is supplied to the sediment thrown in from the charge port 1, and the sediment and the filling fluid are stirred and mixed by the rotation of the crusher D for crushing a soil clod and a rock in the housing. In addition, when a transfer chamber in the rotor R of the pressure feed device T attains at the lowest stage, the mixture of the earth and sand and injected fluid in the transfer chamber is fed into the transporting pipe Tp by compressed air. Thus earth filling and the improvement of ground can be simultaneously carried out.
