Iphepha: Ukuyila ngokutsha iBenchmark yoBunjineli bokuNqanda amanzi phantsi komhlaba "ngesakhiwo esiguquguqukayo"
Kwiinkqubo zokungangenwa kwamanzi zeprojekthi zeziseko ezifihlakeleyo—ezifana neetonela, ii-subways, kunye nee-corridors ezidityanisiweyo zangaphantsi komhlaba—ukukhethwa kwezinto kumisela ngokuthe ngqo ubomi bokhuseleko lweprojekthi kunye neenzuzo zendalo. Njengovulindlela ozinikeleyo kwicandelo lezinto zokwenziwa komhlaba, iShandong Hongyue Environmental Protection Engineering Co., Ltd. (ebizwa ngokuba yi-"Hongyue Environmental") ikhula ngokuthe ngcembe njenge-"flexible" (i-flexible mainstay) ekungangenwa kwamanzi kwiindawo zanamhlanje zangaphantsi komhlaba kunye nezakhiwo zetonela. Isebenzisa imveliso yayo ephambili—iphepha lokungangenwa kwamanzi le-EVA (Ethylene-Vinyl Acetate Copolymer)—inkampani yahlulahlula ngeenzuzo eziphambili ezifana “nokuguquguquka okungaqhelekanga, ukuba nobuhlobo nendalo, kunye nokuqina okuqinileyo.”
Ukuguquguquka Okumangalisayo kunye nokusebenza kobushushu obuphantsi: Ukuphelisa uxinzelelo lwesakhiwo
Eyona nto ibalulekileyo kwezobuchwepheshe kwi-EVA Environmental's EVA manzi angenamanzi ikwiimpawu zayo "zesakhiwo esiguquguqukayo", ezifana nezerabha. Ukungeniswa kwee-vinyl acetate monomers kwisakhiwo sayo se-molecular kunciphisa kakhulu ubukhristalo bayo, kunika izinto izinga eliphezulu kakhulu lokwandiswa (≥650%). Kwizicelo zobunjineli ezingaphantsi komhlaba, ifunxa ngempumelelo uxinzelelo lwe-shear olubangelwa kukuhlala kancinci kweendawo ze-tunnel okanye ukuguqulwa kwesiseko. Isebenza njenge "nxalenye yesakhiwo esiguquguqukayo," ithintela ukuqhekeka okuhlala kuhlutha izinto zemveli eziqinileyo zokuthintela amanzi xa ziphantsi kokuguqulwa kwesakhiwo. Ngaphezu koko, ukusebenza kwayo okuphezulu kobushushu obuphantsi kuqinisekisa ukuba igcina ukuqina okuhle kakhulu - ngaphandle kokuba buthathaka okanye ithambekele ekuqhekekeni - nokuba kwiindawo eziqatha ukusuka kwi -30°C ukuya kwi -35°C. Oku kuyenza ifaneleke ngokupheleleyo kwiimfuno zokwakha kwiindawo ezibandayo zasentla naphantsi kweemeko ezahlukeneyo zejoloji ezinzima.
I-Eco-Friendly and Chemical Deserves: Ukukhusela iSiseko se-Ecological
Kule mihla yophuhliso lweziseko eziluhlaza, iimpawu ezilungele ukusingqongileyo zephepha lokungangenisi manzi le-EVA le-Hongyue Environmental zixatyiswa kakhulu. Le mveliso ngokwayo ayinabungozi kwaye ayinabungozi; ayivelisi ungcoliseko ngexesha lokuveliswa okanye ukusetyenziswa, ivelisa inkunkuma encinci, kwaye ihambelana ngokupheleleyo nemigangatho yokwakha eluhlaza. Kwangaxeshanye, izinto ze-EVA zibonisa uzinzo olubalaseleyo lweekhemikhali, zichasa ngempumelelo ukugqwala okuvela kwii-asidi, ii-alkalis, kunye nezinye izinto ezahlukeneyo zeekhemikhali, ngelixa zikwabonisa ukumelana okuhle kakhulu ne-hydrolysis. Nokuba zisetyenziswa kwiindawo zokulahla inkunkuma zasezidolophini ukuthintela ungcoliseko lomhlaba oluphumayo, okanye zisetyenziswa kwiindawo ezintsonkothileyo ezingcolisayo ezifana nezityalo zeekhemikhali kunye nemisebenzi yemigodi, iseka umqobo okhuselekileyo nothembekileyo ongenakungena-ongashiyi mpembelelo imbi kwimithombo yamanzi engaphantsi komhlaba okanye kwindalo esingqongileyo.
Ukuqina Okuqinileyo Nokumelana Nokubhoboza: Ukuqinisekisa Ukusebenza Kweprojekthi Ixesha Elide
Ngaphaya kokuguquguquka kwayo okuqhelekileyo, iHongyue Environmental isebenzisa inkqubo yokuphuma ethe tye kakhulu ekuveliseni ii-membrane zayo zokuthintela amanzi kwi-EVA. Ngaphezu koko, ngokuxhomekeke kwiimfuno ezithile zeprojekthi, ii-membrane zinokugqunywa nge-geotextiles okanye ziphathwe ngenkqubo yokuncamathelisa ngesanti, zinike amandla okutsalwa angaqhelekanga, ukumelana nokukrazula, kunye nokumelana nokubhoboza. Olu lwakhiwo oludibeneyo alugcini nje ngokuphucula ukuthembeka kwesakhiwo se-membrane kodwa lukhusela ngokufanelekileyo kumonakalo woomatshini ngexesha lokwakhiwa kunye nomonakalo wokungena obangelwa ziinkqubo zeengcambu zezityalo. Ngenxa yokumelana kwayo nemozulu ephezulu kunye nokuzinza kwe-UV, le nto idla ngokusebenza iminyaka emininzi—nokuba ivezwe kwizinto eziphila phantsi komhlaba okanye ingcwatywe phantsi komhlaba—ngaloo ndlela inciphisa kakhulu iindleko zokugcinwa kunye nokutshintshwa kweprojekthi kwixesha elizayo.
Ukufakelwa okulula kunye nokuguquguquka okuguquguqukayo: Ukuphucula ukusebenza kakuhle kweprojekthi
Iimembrane ze-EVA zokuthintela amanzi zeHongyue Environmental zibonisa ukuguquguquka okumangalisayo ngexesha lokufakelwa. Iimpawu zazo ezibalaseleyo zokuvala ubushushu zenza ukuba ukuwelda kwindawo kube lula kakhulu, nto leyo ebangela ukuba kubekho imithungo yokuwelda eqinileyo kwaye ivalwe kakuhle. Ngaphezu koko, imveliso ifumaneka kuluhlu olubanzi lobukhulu (umz., 0.8 mm ukuya kwi-2.0 mm) kunye nobubanzi (ngesiqhelo ziimitha ezi-3 ukuya kwi-4 metres), okuvumela ukuba kuhlengahlengiswe ngokulula kwiimeko ezahlukeneyo zobunjineli—kuquka iitonela ezithe tye, iindawo ezigobileyo, kunye neekhorido ezincinci zokusetyenziswa. Uyilo olubanzi lunciphisa kakhulu inani lemithungo kwindawo; xa idityaniswe nendlela yokufaka "i-zoned tensioning" ephuculweyo ngokwesayensi, le ndlela inyusa kakhulu ukusebenza kakuhle kokwakha kwaye inciphisa amaxesha eprojekthi.
Isebenzisa ezi zibonelelo zikhethekileyo, ii-membranes ze-EVA zokuthintela amanzi zeShandong Hongyue Environmental ziye zamkelwe ngokubanzi kumacandelo amaninzi, kuquka ii-tunnels zothutho, iiprojekthi zokugcinwa kwamanzi kunye nokulawula ukuvuza kwamanzi, iindawo zokulahla inkunkuma, kunye neziseko zophuhliso ezingaphantsi komhlaba zikamasipala. Ixhasa ifilosofi ethi "Ubuchule bobuchwephesha, Umgangatho kuqala," i-Hongyue Environmental inika isiqinisekiso sokhuseleko esiqinileyo nesihlala ixesha elide kwimigca yokhuselo efihlakeleyo yeziseko zophuhliso zanamhlanje—inikezela ngee-membranes ze-EVA zokuthintela amanzi ezisebenza kakuhle ezenzelwe "ukuxhathisa ukuguquka" kunye "nokumelana nokugqwala."
