Ngenxa yokusebenza kakuhle kwesakhiwo kunye neenzuzo zobugcisa ezicacileyo, izakhiwo zesakhelo sentsimbi ziye zaba ngumqolo wezakhiwo zanamhlanje kunye namandla anamandla okuqhuba uphuhliso lwedolophu. Njengoko izixeko zisanda ngobukhulu nangobuninzi, izakhiwo kufuneka zifezekise ukusebenza kakuhle, ukhuseleko olungcono, kunye nokuhanjiswa ngokukhawuleza. Iinkqubo zesakhelo sentsimbi zisabela ngokufanelekileyo kwezi mfuno kwaye ngoku zithatha indawo ephambili kwiiprojekthi zokwakha zoshishino, zorhwebo, kunye noluntu kwihlabathi liphela.
Ulwakhiwo lwanamhlanje alusajolisi kuphela kutyalo-mali lokuqala. Abaphuhlisi kunye nabanini ngoku bavavanya iindleko zomjikelo wobomi, ukulungelelaniswa kwesakhiwo, kunye nokusebenza kwexesha elide. Izakhiwo zesakhelo sentsimbi zihambelana kakuhle nezi zinto ziphambili. Iimpawu zazo zoomatshini, ingqiqo yokwakha, kunye nokusebenza kakuhle kwezinto zibonelela ngeenzuzo ezicacileyo kulo lonke uyilo, ulwakhiwo, kunye nezigaba zokusebenza.
Iingenelo eziPhambili zeZakhiwo zeSakhelo seNsimbi
Amandla aphezulu, uyilo olukhaphukhaphu, kunye nolwakhiwo olusebenzayo zichaza iingenelo eziphambili zeefreyimu zentsimbi. Intsimbi yesakhiwo idla ngokufikelela kumandla okuvelisa phakathi kwe-345 MPa kunye ne-460 MPa. Eli nqanaba lidlula elo lekhonkrithi eqhelekileyo ngokuphindwe ngaphezulu kweshumi. Amandla aphezulu avumela amalungu entsimbi ukuba athwale imithwalo emikhulu eneziqendu ezincinci. Ngenxa yoko, izakhiwo zifumana indawo engakumbi yangaphakathi esebenzisekayo ngelixa zigcina ukhuseleko lwesakhiwo.
Iifreyimu zentsimbi nazo zinciphisa ubunzima bokwakha. Ubunzima obuqhelekileyo beefreyimu zentsimbi bumalunga nama-55 kg ngemitha yesikwere. Eli nani lihlala liphantsi ngama-35–45% kunobo bezakhiwo zekhonkrithi eziqinisiweyo. Ubunzima obuphantsi bokuzilawula kunciphisa imithwalo ethe nkqo kwiziseko. Kukwanciphisa nomthamo wokumba kunye nokusetyenziswa kwekhonkrithi. Oku kunciphisa kunceda ukulawula iindleko zesiseko, ingakumbi kwiimeko zomhlaba obuthathaka.
Isantya sokwakha sibonisa enye inzuzo enkulu. Izixhobo zentsimbi ziyalungiswa kwindawo yefektri ngolawulo olungqongqo lomgangatho. Umsebenzi owenziwa kwindawo ugxila ekuhlanganiseni endaweni yokwenza izinto. Xa kuthelekiswa nezakhiwo zekhonkrithi eziqinisiweyo, iiprojekthi zesakhelo sentsimbi zihlala zinciphisa iishedyuli zokwakha ngama-30–40%. Umzekelo, isakhiwo seofisi esinezitezi ezininzi ezingama-5,000 m² esisebenzisa inkqubo yesakhelo sentsimbi sinokugqitywa kwiinyanga ezintandathu. Isakhiwo sekhonkrithi esifanayo sidla ngokufuna iinyanga ezisithoba kuba ikhonkrithi ifuna ukugalelwa, ukucocwa, kunye nophuhliso lokuqina.
Iingenelo zoLawulo loMgangatho kunye nokuZinza
Ukwenziwa okusekwe kwifektri kuphucula ukuchaneka kobukhulu kunye nomgangatho woqhagamshelo. Imveliso elawulwayo inciphisa inkunkuma yezinto kunye namazinga okuphinda kusetyenziswe. Ezi zinto zonyusa ukuthembeka kunye nokuqikelelwa kolwakhiwo ngokubanzi. Izakhiwo zentsimbi zikwaxhasa ukwakhiwa kwemodyuli kunye nokufakelwa ngezigaba. Ukuguquguquka okunjalo kunceda iiprojekthi ezineshedyuli exineneyo okanye izinto ezintsonkothileyo.
Ngokwembono yozinzo, izakhiwo zesakhelo sentsimbi zibonisa iingenelo ezinamandla. Intsimbi ingasetyenziswa kwakhona ngokupheleleyo ngaphandle kokulahlekelwa kukusebenza koomatshini. Ekupheleni kwexesha lokusebenza kwesakhiwo, amalungu entsimbi angangena kwimijelo yokusetyenziswa kwakhona okanye yokusetyenziswa kwakhona. Olu phawu lunciphisa impembelelo yokusingqongileyo kwaye luhambelana nemigangatho yesakhiwo esiluhlaza. Ukuncipha komsebenzi wokumanzi kwindawo kukwanciphisa uthuli, ingxolo, kunye nokusetyenziswa kwamanzi ngexesha lokwakhiwa.
Ukhuseleko, Ukusebenza kweNyikima, kunye nokuQina
Ukusebenza kokhuseleko kuhlala kuyinto ebalulekileyo ekukhetheni ulwakhiwo. Izakhiwo zesakhelo sentsimbi zibonisa ukumelana okuhle kakhulu nokushukuma ngenxa yokuguquguquka kwentsimbi kunye namandla okusasaza amandla. Phantsi komthwalo wesakhelo sentsimbi, iifreyimu zentsimbi ziyaguquguquka ngendlela elawulwayo endaweni yokuba zingasebenzi ngequbuliso. Ngexesha lenyikima ye-intensive-8, izakhiwo zesakhelo sentsimbi zinokugcina umlinganiselo wokushukuma phakathi kwesakhiwo ungaphantsi kwe-1/250. Olu hlobo lokuziphatha lunciphisa kakhulu umngcipheko wokuwa kwaye lunciphise umonakalo wesibini.
Ukuqina kwayo kuphucula ixabiso lexesha elide lokwakhiwa kwesakhelo sentsimbi. Iinkqubo zokugquma ezishushu kunye neenkqubo zokugquma zanamhlanje zikhusela amalungu entsimbi ekuboleni. Ngokulungiswa ngokufanelekileyo, izakhiwo zesakhelo sentsimbi zinokufikelela kubomi benkonzo obudlula iminyaka engama-80. Ngokwahlukileyo koko, izakhiwo zesakhelo sentsimbi zihlala zichaphazeleka yi-carbonation, ukungena kwe-chloride, imvula ye-asidi, okanye iindawo zaselwandle. Ezi zinto zikhawulezisa ukubola nokuqhekeka kokuqina. Ngexesha elide lenkonzo, izakhiwo zesakhelo sentsimbi zihlala zijongene neendleko zokugcinwa eziphezulu ngama-30% kunezo zezakhiwo zesakhelo sentsimbi.
Uthelekiso Phakathi Kweefreyimu Zentsimbi Nezakhiwo Zefreyimu Yesango
Izakhiwo zesakhelo sentsimbi kunye nezakhiwo zesakhelo sesango zombini zezeenkqubo zokwakha zentsimbi, kodwa zisebenza ngeenjongo ezahlukeneyo. Inkqubo nganye inika iingenelo phantsi kweemeko ezithile zoyilo.
Izakhiwo zefreyimu yesango zisebenza ikakhulu kwizakhiwo zoshishino ezinemigangatho enye kunye neendawo zokugcina impahla ezinobubanzi obuphakathi kweemitha ezingama-30 nama-60. Ezi zakhiwo zihlala zifuna iindawo ezinkulu ezingenazikholamu kunye noyilo oluphindaphindwayo. Kwiimeko ezinjalo, uyilo lwefreyimu yesango ludla ngokufezekisa iindleko zokwakha eziphantsi. Amalungu athambileyo alungiselelweyo anciphisa ukusetyenziswa kwentsimbi ngelixa egcina amandla aneleyo. Amalungu aqinileyo alula aphucula isantya sokuma.
Izakhiwo zesakhelo sentsimbi zisebenza ngcono kwizakhiwo ezinemigangatho emininzi ezifana neenqaba zeeofisi, iindawo zokuthenga, kunye nophuhliso oluxutyiweyo. Ezi zakhiwo zifuna ukuqina okuphezulu ecaleni, indibaniselwano eyahlukeneyo yomthwalo, kunye nokulungiswa kwendawo okuguquguqukayo. Izakhelo zentsimbi ziyahlangabezana nezi mfuno ngeenkqubo zemiqadi-ikholamu, iinkqubo zokuxhasa, okanye uqhagamshelo olumelana nomzuzu. Nangona kunjalo, ukwanda kobunzima bokwenziwa kunyusa iindleko zabasebenzi kunye nobude bokwakha.
I-Economic Logic kunye neemeko zokusetyenziswa
Izakhiwo zefreyimu yeportal zixhomekeke kwiindlela zomthwalo ezilula kunye nezinto ezimbalwa. Oku kulula kugcina iindleko zokwenza, zokuthutha, kunye nokufakela ziphantsi. Kubaphuhlisi abagxile kulawulo lweendleko kwizakhiwo zoshishino, iifreyimu zeportal zihlala zimela isisombululo esingabizi kakhulu.
Izakhiwo zesakhelo sentsimbi ziquka iinkqubo ze-node ezintsonkothileyo kunye neendlela ezahlukeneyo zonxibelelwano. Ezi mpawu zivumela uyilo oluguquguqukayo, ukwandiswa ngokuthe nkqo, kunye notshintsho olusebenzayo lwexesha elizayo. Abayili banokulungiselela izicwangciso ezingaqhelekanga kunye nokubalwa komgangatho ophezulu kunye nemida embalwa. Ukuguquguquka okunjalo kongeza ixabiso kwiiprojekthi zasezidolophini nakwizorhwebo.
Ubudlelwane beendleko phakathi kwezi nkqubo zimbini buxhomekeke kwiimeko zeprojekthi. Kwizakhiwo zoshishino ezineendawo ezinkulu kakhulu, iikhreyini ezinzima, okanye iimfuno ezingqongqo zenyikima, iinkqubo zesakhelo sentsimbi zinokufikelela kwiindleko eziphantsi. Ukusebenza kakuhle kwesakhiwo kunye nokusasazwa okungcono komthwalo kunciphisa imfuno yezinto kwaye kuphucule ukusebenza.
