Iindaba

I-geomembrane edibeneyo isetyenziswa ngokubanzi kubunjineli bokuthintela umjelo. Kwiminyaka yakutshanje, ukusetyenziswa okubanzi kunye nokusebenza kakuhle kwedatha yokubola kwe-geotechnical kubunjineli boluntu, ngakumbi kulawulo lwezandyondyo kunye neeprojekthi zokuhlangula ezingxamisekileyo, kuye kwatsala ingqalelo ephezulu kwiingcali zobunjineli ezithambileyo. Ngokubhekiselele kubuchule bokusetyenziswa kwedatha yokubola ye-geotechnical, urhulumente wenze isindululo sobuchule obusemgangathweni bokuthintela ukuntywila kwamanzi, ukuhluzwa, ukuhambisa amanzi, ukuqinisa, kunye nokukhusela, okukhawulezisa kakhulu ukukhuthazwa nokusetyenziswa kwedatha entsha. Olu lwazi lusetyenziswe ngokubanzi kwiiprojekthi zokuthintela ukuchithwa kwe-canal kwiindawo zokunkcenkceshela. Ngokusekwe kwithiyori yolwakhiwo oludibeneyo, eli phepha lixoxa ngeendlela zokusetyenziswa kwe-geomembrane edibeneyo.

I-geomembrane ehlanganisiweyo yi-geomembrane edibeneyo eyenziwe ngokufudumeza elinye okanye omabini amacala enwebu kwi-oven ekude ye-infrared, ukucinezela i-geotextile kunye ne-geomembrane kunye nge-roller yesikhokelo. Ngenkqubela phambili yeteknoloji yabasebenzi, kukho enye inkqubo yokuphosa i-geomembrane edibeneyo. Le meko ibandakanya ilaphu elinye nefilimu enye, amalaphu amabini kunye nefilimu enye, kunye nefilimu ezimbini nelaphu elinye.
Njengomaleko okhuselayo we-geomembrane, i-geotextile ikhusela umaleko okhuselayo kunye nongenamanzi ukuba wonakaliswe. Ukuze kuncitshiswe imisebe ye-ultraviolet kunye nokwandisa ukusebenza, kuyacetyiswa ukuba uthabathe indlela yokufakela yokubeka.
Ngethuba lokwakha, sebenzisa kuqala isanti okanye udongwe kunye nobukhulu obuncinci bezinto eziphathekayo ukuze ulinganise umgangatho wesiseko, kwaye ubeke i-geomembrane. I-geomembrane akufanele yolulwe ngokuqinileyo kakhulu, kunye neziphelo zombini zingcwatywe emhlabeni kwimilo ye-corrugated. Okokugqibela, sebenzisa isanti ecolekileyo okanye udongwe ukubeka umaleko we-10cm wenguqu kwi-geomembrane egangathiweyo. Yakha amatye ebloko angama-20-30cm (okanye iibhloko zekhonkrithi ezakhiwe ngaphambili) njengomaleko okhuselayo kukhukuliseko. Ngexesha lokwakha, kufuneka kwenziwe iinzame zokuthintela amatye ekubetheni ngokungathanga ngqo kwi-geomembrane, ngokukhethekileyo ukuyeka ukwakhiwa kwekhaka ngelixa ubeka i-membrane. Ukudibanisa phakathi kwe-geomembrane edibeneyo kunye nezakhiwo ezijikelezileyo kufuneka zixhaswe ngeebholiti zokunciphisa kunye neentsimbi zeplate yensimbi, kwaye ukudibanisa kufuneka kufakwe nge-asphalt emulsified (2mm ubukhulu) ukwenzela ukubamba ukuthintela ukuvuza.
Isiganeko sokwakha
(1) Uhlobo olungcwatyiweyo luya kwamkelwa ukuze lusetyenziswe: ubukhulu bokugquma abuyi kuba ngaphantsi kwe-30cm.
(2) Inkqubo ehlaziyiweyo ye-anti-seepage kufuneka ibe ne-cushion, i-anti-seepage layer, i-transition layer, kunye ne-shield layer.
(3) Umhlaba kufuneka uthambile ukuthintela ukuhlaliswa kokungalinganiyo kunye neentanda, kwaye ingca kunye neengcambu zemithi phakathi koluhlu olungenakungena kufuneka zisuswe. Beka isanti okanye udongwe kunye nobukhulu bamasuntswana amancinci njengomaleko okhuselayo kumphezulu ngokuchasene ne-membrane.
(4) Xa ubeka, i-geomembrane akufanele itsalwe ngokuqinileyo. Kungcono ukubethelela iziphelo zozibini emhlabeni ngendlela yamalahle. Ukongezelela, xa i-anchoring kunye nedatha eqinile, umlinganiselo othile wokwandisa kunye nokunciphisa kufuneka ugcinwe.
(5) Ngexesha lokwakha, kuyimfuneko ukukhusela amatye kunye nezinto ezinzima ngokubetha ngokungathanga ngqo kwi-geomembrane, ukwakha ngelixa ubeka i-membrane, kwaye ugubungele umgca wokukhusela.
