垃圾场边坡HDPE土工膜摩擦系数及糙面土工膜稳定性施工方法

垃圾场边坡HDPE土工膜摩擦系数及糙面土工膜稳定性施工方法
垃圾填埋场边坡瑞恒牌HDPE土工膜的摩擦受力铺设在垃圾场边坡，在垃圾填埋场中边坡稳定性很重要,稳定的糙面HDPE土工膜可以隔离垃圾体与边坡周围环境,避免HDPE土工膜滑落。在土工膜上填埋垃圾和土层,沿其长度方向将有剪应力。生活垃圾处理采用日本卫生填埋处理工艺,采用五层防渗,整个场地推平后先铺30厘米厚粘土,压实后,铺一层无纺土工布,一层2毫米厚HDPE土工膜,再一层无纺土工布,即“两布一膜”,作为保护层和防渗衬层,其上面再铺50厘米厚压实的粘土层,整个防渗系统可确保垃圾渗滤液不进入地表或地下水体中。填埋场底部及中间部位均铺设由鹅卵石和横竖排列的有孔管组成的渗滤液收集管网,收集的渗滤液通过底层收集主管排到容量为8万立方米的调节池。Landfill slope HDPE geotechnical membrane friction coefficient and stability of construction method

The force of friction landfill slope Ruiheng brand HDPE geomembrane laying in the dump slope, in landfillslope stability is very important, HDPE geotechnical membrane stability can isolate waste from the surrounding environment to avoid slope, HDPE geotechnical membrane. Geotechnical membrane in landfilland soil, along its length direction will have shear stress. Domestic waste treatment using Japanese sanitary landfill treatment process, using five layers of seepage, the entire site leveling after the first shop 30 cm thick clay, after compaction, laying a layer of nonwoven geotextiles, a layer of 2 mm thick HDPE geotechnical membrane, then a layer of nonwoven geotextiles, namely "two cloth of a film", as protective layer and the liner,the clay layer is paved 50 cm thick compacted, the whole control system ensures that the leachate does not enter the water surface or underground. The landfill bottom and middle part are laying by the arrangement ofpebbles and horizontal perforated pipe of leachate collection pipe network, collect the leachate collectioncharge through the bottom row to a capacity of 80000 cubic meters of regulation pool.
