The purpose landfill final cover closure system is to limit precipitation infiltration inside the landfill to minimize the intrusion of water output may leachate. The closure system, the function of surface water discharge guide layer is covered with soil moisture infiltration discharge to 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 hdpe Geo network, 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 Geo network, and the use of geotextile composite drainage network, can be applied to a steeper slope closure, also possible to increase the volume of landfill waste. Three-dimensional geotextile composite drainage network with high conductivity row performance, 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 geotextile mat, 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 bulk Geo network, can be applied to steep slopes, its high performance can lead row and remove water seepage and gas, ensure slope stability. Geotextile net effect of a enhance road stability, prevent cracks; 2, can withstand greater variable load; 3, pavement cracks caused Frothing prevented; 4, can reduce the amount of pavement materials, speed up the construction speed.
