Uma abantu bekhuluma ngobuchwepheshe obuluhlaza, bavame ukuthwebula amaphaneli elanga, izinjini zomoya, noma amabhethri e-EV. Cishe akekho ocabanga ngale izingxenye ezishumekiwe - amahange, izinto ezifakiwe, izinduku ezinentambo ezibamba lezi zakhiwo ezinkulu ndawonye. Lena indawo eyimpumputhe evamile. Eqinisweni, uma lezi zingxenye zehluleka, lonke uhlelo ‘oluluhlaza’ lungawela phansi, ngokwezwi nezwi. Okuhlangenwe nakho kwami ​​kube ukuthi ukusimama kwephrojekthi kuvame ukuncika kulezi zingcezu zehadiwe ezingabonakali, ezigqitshiwe. Akukhona nje mayelana nokusebenzisa insimbi egaywe kabusha; imayelana nobunjiniyela ukuthi buhlale iminyaka engama-30 endaweni ebhidlizayo yasogwini noma ngaphansi kokuhamba ngamabhayisikili ashisayo. Yilapho inselelo yangempela ilele khona.

Umbono Oyiphutha wokuthi 'I-Bolt Nje'

Ngike ngahlala emihlanganweni lapho ukuthengwa kwempahla kuphusha khona isibambiso esibiza kakhulu sesistimu yokukhweza epulazini lelanga. I-logic ilula: iyinsimbi nje, igqitshwe kukhonkolo, ingaba bucayi kangakanani? Lokhu kunciphisa ngokuyingozi. I-galvanized ingxenye eshumekiwe enhlabathini ene-chloride ephezulu ingagqwala ngokushesha kunalokho obekulindelwe. Ngike ngabona amaphrojekthi okubuyisela emuva lapho lonke iqembu bekufanele linqanyulwe ngenxa yokuthi amahange ayisisekelo ayesengozini. Izindleko zokushintsha lezo izingxenye ezishumekiwe idlule imali yokuqala eyongiwe ngokuphindwe kashumi. Kuyisifundo ezindlekweni eziphelele zobunikazi ukuthi imboni isafunda kancane kancane.

Incazelo yiyo yonke into. Kuphrojekthi yakamuva ye-agro-voltaic, asikwazanga ukusebenzisa i-hot-dip galvanizing evamile. I-ammonia eguquguqukayo epulazini ngaphansi kwamaphaneli idale ingozi ethile yokugqwala komkhathi. Sigcine ngokucacisa isistimu yokuhlanganisa i-duplex - i-zinc kanye ne-polymer sealant - yabo bonke insimbi eshumekiwe izingxenye. Kwakuyimininingwane, kodwa ukuwenza ngendlela engalungile kwakuyoholela ekuhlulekeni ngaphambi kwesikhathi kanye nenhlabathi engcolile. Isici esiluhlaza akuwona nje amandla akhiqizwayo; iqinisekisa ukuthi ukufakwa akudali inkinga yesikhathi esizayo yokumosha noma yokungcola.

Yilapho abakhiqizi abakhethekile bebalulekile khona. Udinga umphakeli oqonda lezi zinto ezicindezela imvelo, hhayi nje okhipha izinduku ezijwayelekile ze-M20. Ngisebenze nezimboni eziyitholayo. Isibonelo, i-Handan Zitai Fastener Manufacturing Co., Ltd., ezinze endaweni enkulu yokukhiqiza izinsimbi zaseChina e-Yongnian, e-Handan, ivamise ukubhekana nalezi zicelo zesiko, eziqondene nendawo ethile.

Konke ngenzelwe ukusungula izinto ezintsha, kodwa ngiphinde ngakubona ukuhluleka komshayeli wendiza. Sivivinye induku eyinhlanganisela yamandla aphezulu endaweni yephampu yokushisa kwe-geothermal. Ithiyori yayiphelele: i-non-corrosion, i-carbon efakwe ngaphansi.

Empeleni, ukunwetshwa okushisayo okuhlukile phakathi kwenduku eyinhlanganisela kanye ne-grout kakhonkolo ezungezile kwakha ama-micro-fractures phakathi nezinyanga eziyi-18 nje kuphela, okuvumela ukungena kwamanzi futhi kuholele ekulahlekeni kokubamba kwesakhiwo. Sibuyele ku-alloy yensimbi evamile, evikelwe ukugqwala. Isifundo bekungekona ukugwema izinto ezintsha, kodwa ukuzivivinya ngaphansi kwesikali esigcwele, ingcindezi yomhlaba wangempela kanye nemijikelezo yemvelo, hhayi nje izimo zelebhu. ‘Ubuhlaza’ bengxenye ehluleka kusenesikhathi inguziro.

Kwesinye isikhathi, ukukhetha okuzinzile yizinto ezihlala isikhathi eside, ezicaciswe ngokuphelele zendabuko. Ukuphila kwayo isikhathi eside kugwema ukushintshwa, ukumba, kanye nokucutshungulwa kwezinto ezintsha. Lokhu kuhlaziywa komjikelezo wempilo kuya kuba semqoka. Manje sesiqala ukucela i-Environmental Product Declarations (EPDs) ngokuyinhloko izinto ezishumekiwe, okucindezela abakhiqizi ukuthi banikeze idatha esobala kakhudlwana ezinqubweni zabo. Ukushintsha kancane, kepha kuhambisa inaliti isuka ezimangalweni ezingacacile iye ekucacisweni okuqinisekiswayo.

I-Logistics kanye ne-On-Site Gamble

Imininingwane akekho okhuluma ngayo aze abe kusayithi elikude: ukupakishwa nokuhlonza. U-oda amaphalethi angu-50 ngokwezifiso amahange ashumekiwe okwepulazi lomoya. Ziyafika, futhi amathegi enombolo yokushisa ukuze alandeleke kahle ayasuswa emvuleni ngesikhathi sokuthutha, noma izigqoko zokuvikela iziphetho ezinentambo azikho. Manje usunenqwaba yezingxenye ezibizayo, ezibalulekile zemishini ezinokuvikelwa kokubola futhi ayikho indlela yokuqinisekisa ukuqinisekiswa kwazo kokubalulekile. Ingabe uyawafaka futhi unethemba, noma ubambezele ukuthululwa kwesisekelo ngamaviki?

Ngibhekane nalokhu. Sakhetha ukulibala. Ubungozi bokufaka ingxenye engaqinisekisiwe, ikakhulukazi ohlelweni olubucayi lokukhathala njengesizinda se-wind turbine, bukhona.
