The present invention discloses a system for consolidating soft clay by combined anode boosting and electro-osmosis, comprising a vacuum preloading system, wherein the vacuum preloading system comprises anode tubes, cathode tubes, a power supply, a boosting device, sealing cloth and a pumping and drainage device; the sealing cloth is covered above soft clay; air vents are formed on side faces of the cathode tubes and the anode tubes; the cathode tubes and the anode tubes are connected to a boosted pumping and drainage pipe above the soft clay through pipelines; the boosted pumping and drainage pipe is configured with the boosting device and the pumping and drainage device; and, the anode tubes and the cathode tubes are connected to an anode and a cathode of the power supply, respectively. The present invention further provides a method for consolidating soft clay by using the system for consolidating soft clay by combined anode boosting and electro-osmosis. In the present invention, after the anode tubes are configured with a boosting device, a gas can be fed into the anode tubes; under the combined action of the high-pressure gas and the anode tubes, water is squeezed to the cathode tubes, so that water can be drained from the soil more thoroughly.

The present invention discloses a system for consolidating hydraulic reclamation silt by combined flocculation and deep boosted vacuum preloading, comprising an agitation tank, wherein the agitation tank is connected to a flocculant preparation tank and a slurry delivery device; a tank bottom valve and a filter plate mechanism are successively arranged at a lower delivery port of a precipitation zone of a dehydration tank; weep holes are formed on filter plates; there is a discharge zone below the precipitation zone of the dehydration tank; a drainage plate is provided on an upper side wall of the precipitation zone; a water storage coaming is provided outside the drainage plate; the water storage coaming and the drainage plate are enclosed to form a water storage zone; the water storage zone is connected to a reservoir via a second delivery pipe with a second delivery pump provided thereon; a water pumping port is provided within the discharge zone; the water pumping port is connected to the reservoir via a third delivery pipe with a third delivery pump provided thereon; and, the discharge valve below the discharge zone is connected to a deep boosted drainage tank. The present invention further provides a method for consolidating hydraulic reclamation silt by using the system. The system and the method for consolidating hydraulic reclamation silt implemented by the system can more thoroughly discharge water in the slurry, so that the soil becomes drier and harder and can be directly used in the landfill of earthwork; moreover, a greater amount of water can be collected.
