The purpose landfill closure gas discharge guide layer and surface water discharge guide layer landfill final cover closure system is to limit rainfall infiltration inside the landfill to minimize the intrusion of water output may leachate. Zhenjiang in closure systems customized geotechnical drainage network, function of surface water discharge guide layer is covered with soil infiltration discharge of water, avoid accumulating on the barrier layer. Water will be produced on the closure of excess pore water impermeable layer of stress, may lead to soil vegetation cover slip, closure slope failure. Traditionally used as a sand and gravel site seal surface water discharge guide layer, the steep slopes, sand and gravel cushion of stacked very difficult, and the use of geotextile composite drainage network, can be applied to a steeper slope closure, but also to increase the volume of landfill waste. Three-dimensional geotextile composite drainage network with high conductivity row performance Zhenjiang customized geotechnical drainage network, the ability to exclude surface water seepage closure to ensure the stability of the slope. Closure insufficient gas discharge guide layer landfill closure system exhaust gas discharge guide layer capability or is not set flat gas discharge guide layer, is applied to the impervious layer of the gas pressure is too great, it may lead to closure system to produce destruction. Closure system gas discharge guide layer can use the high conductivity row performance geotextile composite drainage network. The use of high conductivity row three-dimensional geotextile composite drainage network Zhenjiang customized geotechnical drainage network, or geotextile composite drainage net with sand and gravel landfill closure system consisting of a gas discharge guide layer. Landfill closure system using geotextile composite drainage network as surface water discharge guide layer and a gas discharge guide layer, can be applied to steep slopes, its high performance can lead row and remove water seepage and gas Zhenjiang custom Geonet ensure the stability of the slope. Composite drainage network and the lap joint process step composite drainage network laid between the foundation and the main substrate for discharging water between the ground and the substrate, blocking capillary water and effectively incorporated into the edge of the drainage system. Then the composite drainage network and lap joints have a certain process steps, we can use the following steps were reasonable lap, it has a better drainage. 1, composite drainage network must be terminated, geotextile adjacent geonet core material roll along on the lap. 2, adjust the direction of the composite drainage network, the volume of material in the longitudinal direction perpendicular to the road. 3, the direction of the filler stacking direction and Lap geotextile to be consistent. If the composite drainage network laid between the foundation and the base, the need for continuous wedge welding, flat welding or stitching, so geotextile lap top to get fixed. 4, the composite drainage net core network roll of geotextile material adjacent white or yellow plastic tape connecting buckle or polymer, thereby connecting material volume.
