I-membrane ye-HDPE ye-anti-seepage ineempawu ezinamandla zokwandiswa kwe-thermal
I-membrane ye-HDPE ye-anti-seepage ineempawu ezinamandla zokwandiswa kwe-thermal. Ukwandiswa komgca kuya kwandisa okanye kucuthe umkhombandlela wobude kwi-100m ubude benwebu nge-14cm xa ubushushu bunyuka okanye buhla nge-100 ℃. Ngenxa yomahluko omkhulu wamaqondo obushushu phakathi kwemini nobusuku kwezinye iindawo ngexesha lasekwindla (kulinganiswa ukusuka ku 60 ℃ ukuya kuma 200 ℃), kukho umahluko wobushushu obuyi 400 ℃, nto leyo enokubangela umahluko we 56cm kwi 100m ubude be-anti-seepage. inwebu. Ngoko ke, ngexesha lokwakha, kuyimfuneko ukuqwalasela impembelelo yokutshintsha kubude be-membrane ekubekweni umgangatho kunye nokusebenza kakuhle, ngokukodwa kwi-slope ye-slope, ejongene nokuxhoma okanye ukushwabana ngenxa yokwandiswa kunye nokuchithwa kwe-membrane.

Isisombululo kwiMpembelelo yoMahluko woBuqondo kuMgangatho we-HDPE Anti seepage Membrane
Ukwakhiwa kufuneka kunciphise ukubeka iifilimu ngexesha lobushushu obuphezulu okanye obuphantsi emini; Lungisa ubude obubekelwe ifilimu ngokomahluko obushushu obuphakathi; Ifilimu ye-anti-seepage ebekwe kwimihla eyahlukeneyo kufuneka ihlengahlengiswe kwindawo efanayo yokushisa njengokuba ixesha lokugqibela libekwe kwi-welding ukunciphisa imibimbi. Emva kokuziqhelanisa, isisombululo usebenzisa umatshini wokuwelda wengoma ezimbini kukugcina ngokufanelekileyo ububanzi obudlulayo. Ububanzi be-overlap yi-8cm ekuseni, i-10cm emva kwemini, kunye ne-14cm emva kwemini, enokuqinisekisa ukuwelda okugudileyo kweengoma ezimbini zizonke; Nangona kunjalo, i-longitudinal overlap (phakathi kwe-slope kunye nezantsi kwesayithi) kufuneka igcinwe ngokusekelwe kubude be-slope. Ngokuqhelekileyo, ukugqithelana kwe-1.5m ngaphandle konyawo lwe-slope kufuneka kugcinelwe i-40-50cm (i-membrane ebekwe emva kwemini), kwaye ixesha lokudibanisa kunye ne-anti-seepage membrane emazantsi esayithi yintsasa elandelayo (emva kobusuku bobusuku). ibhalansi yokucutha kunye noxinzelelo, ukwandiswa kwayo kunye nokuncipha kwayo kuzinzile ngokusisiseko); Okwesibini, i-welding yeefilimu ezimbini ezikufutshane kufuneka iqhutywe emva kwendawo yokushisa efanayo, ngakumbi xa i-welding ifilimu ibekwe ekuseni kunye nefilimu ebekwe izolo. Le nto kufuneka ithathelwe ingqalelo ngenxa yokuba ifilimu eqengqelekayo ayithinteli utshintsho kwiqondo lokushisa langaphandle, ngelixa ifilimu ebekiweyo inomdla kakhulu kwiiyantlukwano zeqondo lokushisa. Ngaphandle koko, kuya kubangela ukuba imibimbi esecaleni yenzeke kumacala omabini efilimu ye-welding, enye icwecwe, ngelixa enye iyunifomu, Isisombululo asikuko ukuwelda isiqwenga kwangoko emva kokuba sibekwe, kodwa ukulinda isiqingatha seyure ngaphambi kwe-welding. .
