Njengoba izakhiwo zisebenza kahle kakhulu kanye nezinzuzo zobuchwepheshe ezicacile, izakhiwo zohlaka lwensimbi ziye zaba umgogodla wezakhiwo zesimanje kanye namandla amakhulu okuqhuba intuthuko yasemadolobheni. Njengoba amadolobha ekhula ngobukhulu nangobuningi, izakhiwo kumele zifinyelele ukusebenza kahle okuphezulu, ukuphepha okungcono, kanye nokulethwa okusheshayo. Izinhlelo zohlaka lwensimbi zisabela ngempumelelo kulezi zidingo futhi manje zisesikhundleni esiyinhloko kumaphrojekthi okwakha ezimboni, ezentengiselwano, kanye nawomphakathi emhlabeni jikelele.
Ukwakhiwa kwesimanje akusagxili ekutshalweni kwezimali kokuqala kuphela. Abathuthukisi nabanikazi manje bahlola izindleko zomjikelezo wokuphila, ukuzivumelanisa nezimo kwesakhiwo, kanye nokusebenza kwesikhathi eside. Izakhiwo zohlaka lwensimbi zihambisana kahle nalezi zinto eziza kuqala. Izakhiwo zazo zemishini, indlela yokwakha, kanye nokusebenza kahle kwezinto kunikeza izinzuzo ezicacile kuzo zonke izigaba zokuklama, ukwakha, kanye nokusebenza.
Izinzuzo Eziyinhloko Zezakhiwo Zohlaka Lwensimbi
Amandla aphezulu, umklamo olula, kanye nokwakhiwa okuphumelelayo kuchaza izinzuzo eziyinhloko zamafreyimu ensimbi. Insimbi yesakhiwo ivame ukufinyelela amandla okukhiqiza aphakathi kuka-345 MPa no-460 MPa. Leli zinga lidlula elokhonkolo ojwayelekile ngokuphindwe izikhathi ezingaphezu kweshumi. Amandla aphezulu avumela amalungu ensimbi ukuthi athwale imithwalo emikhulu enezingxenye ezincane eziwela phansi. Ngenxa yalokho, izakhiwo zithola isikhala sangaphakathi esisebenziseka kalula ngenkathi zigcina ukuphepha kwesakhiwo.
Ozimele bensimbi nabo banciphisa isisindo sokwakha ngokuphawulekayo. Isisindo esimaphakathi sozimele bensimbi singama-55 kg ngemitha yesikwele. Lesi sibalo sihlala siphansi ngo-35–45% kunesezakhiwo zekhonkrithi eziqinisiwe. Isisindo esiphansi sozimele kunciphisa imithwalo eqondile ezisekelweni. Kuphinde kunciphise umthamo wokumba kanye nokusetshenziswa kwekhonkrithi. Lokhu kunciphisa kusiza ukulawula izindleko zesisekelo, ikakhulukazi ezimweni zenhlabathi ezibuthakathaka.
Ijubane lokwakha limelela enye inzuzo enkulu. Izingxenye zensimbi ziyakhiwa kusengaphambili ezindaweni zasefektri ngokulawulwa okuqinile kwekhwalithi. Umsebenzi wasendaweni ugxila ekuhlanganisweni kunokwakheka kwezinto. Uma kuqhathaniswa nezakhiwo zekhonkrithi eziqinisiwe, amaphrojekthi ohlaka lwensimbi avame ukufinyeza amashejuli okwakha ngo-30–40%. Isibonelo, isakhiwo sehhovisi esinezitezi eziningi esingamamitha-skwele angu-5,000 esisebenzisa uhlelo lohlaka lwensimbi singaqedwa zingakapheli izinyanga eziyisithupha. Isakhiwo sekhonkrithi esifanayo sivame ukudinga izinyanga eziyisishiyagalolunye ngoba ukhonkrithi udinga ukuthululwa, ukuqiniswa, kanye nokuthuthukiswa kwamandla.
Izinzuzo Zokulawula Ikhwalithi Nokuzinza
Ukwenziwa okusekelwe efektri kuthuthukisa ukunemba kobukhulu kanye nekhwalithi yokuxhuma. Ukukhiqizwa okulawulwayo kunciphisa imfucuza yezinto ezibonakalayo kanye namazinga okusebenza kabusha. Lezi zici zandisa ukuthembeka kanye nokubikezela ukwakhiwa okuphelele. Izakhiwo zensimbi nazo zisekela ukwakhiwa kwe-modular kanye nokufakwa ngezigaba. Ukuguquguquka okunjalo kusiza amaphrojekthi anezinhlelo eziqinile noma izinto eziyinkimbinkimbi.
Ngokombono wokuzinza, izakhiwo zohlaka lwensimbi zibonisa izinzuzo ezinkulu. Insimbi ingaphinde isetshenziswe ngokuphelele ngaphandle kokulahlekelwa ukusebenza kahle kwemishini. Ekupheleni kwesikhathi senkonzo yesakhiwo, amalungu ensimbi angangena emifudlaneni yokusetshenziswa kabusha noma yokusetshenziswa kabusha. Lesi sici sinciphisa umthelela emvelweni futhi sihambisana nezindinganiso zokwakha eziluhlaza. Ukunciphisa umsebenzi wokumanzi endaweni kunciphisa nothuli, umsindo, kanye nokusetshenziswa kwamanzi ngesikhathi sokwakha.
Ukuphepha, Ukusebenza Kokuzamazama Komhlaba, Nokuqina
Ukusebenza kokuphepha kusalokhu kuyisici esibalulekile ekukhetheni izakhiwo. Izakhiwo zohlaka lwensimbi zibonisa ukumelana okuhle kakhulu nokuzamazama komhlaba ngenxa yokuguquguquka kwensimbi kanye namandla okusabalala kwamandla. Ngaphansi komthwalo wokuzamazama komhlaba, ohlaka lwensimbi luyaguquguquka ngendlela elawulwayo kunokuba luwe ngokuzumayo. Ngesikhathi sokuzamazama komhlaba okunamandla angu-8, izakhiwo zohlaka lwensimbi zingagcina isilinganiso sokukhukhuleka esingaphansi kuka-1/250. Lokhu kuziphatha kunciphisa kakhulu ingozi yokuwa futhi kunciphise umonakalo wesibili.
Ukuqina kuthuthukisa kakhulu inani lesikhathi eside lokwakhiwa kohlaka lwensimbi. Izinhlelo zokufaka i-galvanizing ezishisayo kanye nezinhlelo zokumboza zesimanje zivikela amalungu ensimbi ekugqwaleni. Ngokulungiswa okufanele, izakhiwo zohlaka lwensimbi zingafinyelela izimpilo zesevisi ezidlula iminyaka engama-80. Ngokuphambene nalokho, izakhiwo zekhonkrithi zivame ukuhlushwa yi-carbonation, ukungena kwe-chloride, imvula ye-asidi, noma izindawo zasolwandle. Lezi zinto zisheshisa ukugqwala nokuqina. Ezinkathini zesevisi ezinde, izakhiwo zekhonkrithi zivame ukubhekana nezindleko zokulungisa eziphakeme cishe ngo-30% kunezakhiwo zohlaka lwensimbi.
Ukuqhathanisa Phakathi Kwamafreyimu Ensimbi Nezakhiwo Zohlaka Lwesango
Izakhiwo zohlaka lwensimbi kanye nezakhiwo zohlaka lwesango zombili zingezezinhlelo zokwakha insimbi, kodwa zifeza izinjongo ezahlukene. Uhlelo ngalunye lunikeza izinzuzo ngaphansi kwezimo ezithile zokuklama.
Izakhiwo zohlaka lwesango zikhonza kakhulu izakhiwo zezimboni ezinesitezi esisodwa kanye nezindawo zokugcina impahla ezinama-span aphakathi kwamamitha angu-30 no-60. Lezi zakhiwo ngokuvamile zidinga izikhala ezinkulu ezingenamakholomu kanye nezakhiwo eziphindaphindwayo. Ezimweni ezinjalo, imiklamo yohlaka lwesango ivame ukufeza izindleko zokwakha eziphansi. Amalungu athambile alungiselelwe anciphisa ukusetshenziswa kwensimbi ngenkathi egcina amandla anele. Amalunga aqinile alula nawo athuthukisa isivinini sokuma.
Izakhiwo zohlaka lwensimbi zisebenza kangcono ezakhiweni ezinezitezi eziningi njengemibhoshongo yamahhovisi, izikhungo zokuthenga, kanye nezakhiwo ezisetshenziswa ngokuxubile. Lezi zakhiwo zidinga ukuqina okuphezulu ohlangothini, inhlanganisela yemithwalo ehlukahlukene, kanye nokuhlelwa kwendawo okuguquguqukayo. Izinhlaka zensimbi ziyahlangabezana nalezi zidingo ngezinhlelo ze-beam-column, izinhlelo zokubopha, noma ukuxhumana okumelana nesikhathi. Kodwa-ke, ukwanda kobunzima bokukhiqiza kuphakamisa izindleko zabasebenzi kanye nobude bokwakha.
Izimo Ze-Economic Logic kanye Nezokusetshenziswa
Izakhiwo zohlaka lwe-portal zithembele ezindleleni zomthwalo ezilula kanye nezingxenye ezimbalwa. Lokhu kulula kugcina izindleko zokukhiqiza, ezokuthutha, kanye nokufaka ziphansi. Kubathuthukisi abagxile ekulawuleni izindleko ezindaweni zezimboni, ohlaka lwe-portal luvame ukumela ikhambi elingabizi kakhulu.
Izakhiwo zohlaka lwensimbi zihilela izinhlelo zama-node eziyinkimbinkimbi kakhulu kanye nezinhlobo zokuxhuma ezahlukahlukene. Lezi zici zivumela ukwakheka okuguquguqukayo, ukunwetshwa okuqondile, kanye nezinguquko zokusebenza zesikhathi esizayo. Abaklami bangakwazi ukwamukela amapulani angajwayelekile kanye nokubalwa kwezitezi eziphakeme ngemikhawulo embalwa. Ukuzivumelanisa nezimo okunjalo kwengeza inani kumaphrojekthi asemadolobheni nakwezentengiselwano.
Ubudlelwano bezindleko phakathi kwezinhlelo ezimbili buxhomeke ezimweni zephrojekthi. Ezakhiweni zezimboni ezinezindawo ezinkulu kakhulu, ama-crane asindayo, noma izidingo eziqinile zokuzamazama komhlaba, izinhlelo zohlaka lwensimbi zingase zifinyelele izindleko eziphansi. Ukusebenza kahle kwesakhiwo kanye nokusatshalaliswa okungcono komthwalo kunciphisa isidingo sezinto futhi kuthuthukise ukusebenza.
