Kutaya zinyalala kuphimba filimu yoyika HDPE Membrane kuyala njira

Zinyalala zapanyumba zotayiramo malo zotayirako zotayirako HDPE Geomembrane ，Kuyika zotchingira zinyalala molingana ndi filimu ya HDPE Overlay yotayirapo. Chifukwa cha malo ophikira ovuta, malo ophimbawo amafika makumi masauzande a masikweya mita, ndipo zolumikizira za mafilimu ophimba zimakhala zazitali, n'zosapeŵeka kuti mafilimu ena ophimba adzakhala ndi kutuluka. Ogwira ntchito kumtunda amagwiritsa ntchito nthawi yawo yaulere kukonza kutayikira kwa mafilimu ophimba. "Filimuyi idayikidwa kwa maola awiri ndi theka m'mawa, ndipo mapepala onse 5 adayikidwa." Kanema wophimba "amatanthawuza za polyethylene geomembrane yochuluka kwambiri yomwe imakutidwa pa zinyalala." Pambuyo pa zinyalala, kuphimba ndi filimuyi n'kofanana ndi kuika a'coat' pa zinyalala, zomwe zingathe kuchepetsa fungo. “

Kuyala ndondomeko ya zinyalala zotayira chophimba filimu

Malo otayirapo zinyalala, kuyatsa zinyalala ndi kuphatikizika sikumasuka. Malo osungiramo zinyalala ali ndi mipanda iwiri ya nthaka kuti agawane malo onse osungiramo malo atatu. Dongosolo la sub-unit landfill la chaka chonse limapangidwa ndipo gawo logwirira ntchito limayendetsedwa molingana ndi zomwe zafotokozedwa, mapaipi a leachate drainage pamipanda ya zoned earth amadulidwa ndikutsekeka, kuthira madzi amvula ndi zimbudzi kumayendetsedwa ku Kuchuluka kwake, kuchuluka kwa leachate komwe kumapangidwa kumachepetsedwa, ndipo kuwopsa kwa chilengedwe ndi ndalama zopangira zimachepetsedwa.

Malo otayirapo nthaka amagwiritsa ntchito makina apadera, ma bulldozers ndi ma compactor popaka ndi kuphatikizira. Kachulukidwe ka zinyalala kachulukidwe ka zinyalala amayesedwa nthawi zonse, kapangidwe ka zinyalala kumawunikidwa nthawi zonse, ndipo kugubuduza kosanjikiza ndi kusanjikiza kumachitidwa ngati pakufunika. Makulidwe amodzi osanjikiza amayendetsedwa pa 0,5 mpaka 1 mita, ndipo makulidwe a unit amawongoleredwa pa 4 mpaka 6 metres.

3,Kuphimbani tsiku ndi tsiku kuti fungo lisafalikire, komanso kuchepetsani madzi amvula kulowa m’dzala, kuletsa kuswana kwa udzudzu ndi ntchentche, komanso kupewa kufalikira kwa fungo.

Malo omwe akugwiritsidwa ntchito pamalo opangira zinyalala adzagwiritsidwa ntchito madzulo aliwonse 1.0 HDPE Nembanemba imaphimbidwa kwakanthawi, ndipo madera onse kunja kwa nkhope yogwira ntchito ndi 1.0 mm Imakutidwa ndi filimu ya polyethylene yapamwamba kwambiri, ndi filimu yophimba m'derali. zomwe sizinagwiritsidwe ntchito kwa masiku opitilira 15 zimalumikizidwa ndikuwotchedwa. Madzi abwino pa filimuyi amatulutsidwa kudzera m'malo otsetsereka kapena ngalande yamadzi amvula yomwe imayikidwa pamalopo, kuti achepetse madzi amvula kuti asalowe m'malo otayira zinyalala, ndikuwongolera bwino kuswana kwa udzudzu ndi ntchentche ndi kufalikira kwa fungo. Ulalo uwu ndi wofunikira kwambiri, makamaka pakupatutsa madzi amvula ndi zimbudzi. M’nyengo yozizira, tidzamaliza kukumba ndi kukonza ngalande zothira madzi osefukira, kukonzanso kwakanthawi kwa misewu m’malo otayiramo zinyalala, kuyendera ndi kukonza mafilimu otchinga, kumanga mizati ya nthaka, kusamutsa ndi kumanga mapampu pasadakhale. Konzekerani mokwanira kulimbikitsa chitetezo chopanga komanso kuchepetsa kuopsa kwa chilengedwe munthawi yamvula. ”

Gawo lolumikizana pakati pa zinyalala ndi malo otsetsereka m'malo osungiramo madzi limayikidwa pa 50 CM Sand thumba loteteza wosanjikiza, malo otsetsereka amawongoleredwa pansipa 1: 3, ndikuwongolera kukwera kwa mulu kumagawika kotsetsereka kotalikirana komanso kopingasa. Malo odzazidwa amatengedwa ndi HDPE Membranes amapatsidwa chithandizo chapakatikati.

4, Palibe chosiyidwa pakupha tizilombo toyambitsa matenda pamalowa. Zopopera zimagwiritsidwa ntchito powonjezera mwachindunji mankhwala m'misewu yomwe ili pamalopo, ndipo mizinga yamphepo imagwiritsidwa ntchito popopera mankhwala ophera tizilombo toyambitsa matenda ndikuchotsa fungo. Panthawi imodzimodziyo, kufalikira kwa magawo ogwirira ntchito kumalimbikitsidwa. Pakali pano, kulamulira kwa udzudzu, ntchentche ndi fungo la malowa ndikwabwino.

Maukonde oletsa kuwuluka amaikidwa kumapeto onse a malo otayiramo kuti atsekere bwino zinthu zowuluka.
