Research on Municipal Solid Waste Sanitary Landfill Leachate Drainage System Layout and Construction Technology

Leach ate drainage system is very important part of the design for municipal solid waste sanitary landfill. Logical design can reduce the water head pressure and landfill leach ate air pressure and provides the necessary conditions for subsequent secondary pollution control. The article discuss arrangement about leach ate guided drainage system, regular practice about HDPE pipes pass through membrane and perforated drainpipe, and dwelt on the construction method of pipeline and gravel drainage layer about Guided drainage systems.
