垃圾場邊坡HDPE土工膜摩擦系數(shù)及糙面土工膜穩(wěn)定性施工方法

垃圾場邊坡HDPE土工膜摩擦系數(shù)及糙面土工膜穩(wěn)定性施工方法
垃圾填埋場邊坡瑞恒牌HDPE土工膜的摩擦受力鋪設(shè)在垃圾場邊坡，在垃圾填埋場中邊坡穩(wěn)定性很重要,穩(wěn)定的糙面HDPE土工膜可以隔離垃圾體與邊坡周圍環(huán)境,避免HDPE土工膜滑落。在土工膜上填埋垃圾和土層,沿其長度方向?qū)⒂屑魬?yīng)力。生活垃圾處理采用日本衛(wèi)生填埋處理工藝,采用五層防滲,整個場地推平后先鋪30厘米厚粘土,壓實(shí)后,鋪一層無紡?fù)凉げ?一層2毫米厚HDPE土工膜,再一層無紡?fù)凉げ?即“兩布一膜”,作為保護(hù)層和防滲襯層,其上面再鋪50厘米厚壓實(shí)的粘土層,整個防滲系統(tǒng)可確保垃圾滲濾液不進(jìn)入地表或地下水體中。填埋場底部及中間部位均鋪設(shè)由鵝卵石和橫豎排列的有孔管組成的滲濾液收集管網(wǎng),收集的滲濾液通過底層收集主管排到容量為8萬立方米的調(diào)節(jié)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.
