PURPOSE: A sanitary landfill using loess ready-mixed concrete is provided to purify the polluted leachate effectively by placing loess ready-mixed concrete on the ground of the sanitary landfill and to prevent the environmental pollution by a sanitary landfill by discharging the polluted leachate rapidly through a drainpipe. CONSTITUTION: The sanitary landfill using loess ready-mixed concrete comprises the steps of forming inner and outer loess ready-mixed concrete layers(2,3) by placing loess ready-mixed concrete on the ground(1) in order, forming a sand column(4) filled up with sand as a filter by forming a space, erecting a drainpipe(5) along an internal wall at regular intervals, burying many drainpipes(5) under a protection net(6), and connecting a guide pipe(7) to the drainpipe(5) and the base of the sand column(4), then to an extraction pipe to drain off leachate easily. |
