Iibholithi ze-turnbuckle zilomeleza njani uzinzo? 

Xa usiva ‘uzinzo’ kulwakhiwo okanye ekurhwebeni, iingqondo ezininzi zitsibela kwiipaneli zelanga okanye intsimbi ehlaziyiweyo. Kunqabile ukuba kubekho umntu ocinga ngothobekileyo ibhonti yebhawunti. Leyo yimpazamo yokuqala. Ikhonkco langempela alikho malunga nempahla ngokwayo, kodwa indlela uyilo lwayo oluguqula ngayo yonke inkqubo yokuphila yesakhiwo. Kumalunga noxinzelelo oluchanekileyo, ixesha elide, kunye nokunciphisa inkunkuma ngokuhlengahlengiswa-izinto ozixabisayo kuphela emva kokubona iprojekthi ingaphumeleli kuba umntu wasebenzisa isisombululo sobude obusisigxina apho ukunyakaza kwakungenakuphepheka.

UmGaqo ongundoqo: uLungiso phezu koTshintsho

Ngokwesiqhelo, uzinzo luhlala luhlala phantsi ekusebenziseni kancinci kwaye ixesha elide. Umsebenzi ophambili we-turnbuckle kukubonelela ngohlengahlengiso olufanelekileyo lokuxinana kwiintambo, iintonga, okanye izibophelelo zesakhiwo. Ngaphandle kolu lungelelaniso, iinkqubo zimile. Xa ukwanda kwe-thermal, ukuhlalisa, okanye imithwalo eguquguqukayo iyenzeka-kwaye zihlala zisenza-izinto ezikhethiweyo zilinganiselwe: mhlawumbi icandelo liyinjineli engaphezulu kunye nemida yokhuseleko olukhulu (ukumosha izinto) okanye iyasilela, ifuna ukutshintshwa ngokuyinxenye okanye ngokupheleleyo. Ndikhumbula iprojekthi yecanopy yendawo yokugcina apho umxhasi wagxininisa kwizibiyeli ezisisigxina zeentambo zokuxhasa. Kwiminyaka emibini, ukuhamba kwexesha lonyaka kubangele ukudinwa kweentanda kwiindawo zokuxhuma. I-retrofit esetyenzisiweyo Iibhotile zokuguqula ukuvumela uhlengahlengiso lonyaka. Loo canopy isamile kwiminyaka elishumi elinesihlanu emva koko. Ukulungiswa kokuqala 'kwexabiso eliphantsi' kwavelisa iitoni zenkunkuma kwintsimbi etshintshwayo kunye nekhonkrithi.

Into yokulungelelanisa yandisa ubomi benkonzo ngokuphawulekayo. Ijika indibano engatshintshiyo ibe yinto egcinekayo. Awukhi nje; wakha kwiprothokholi yokulondoloza kunye nokulungelelanisa. Olu lutshintsho olusisiseko ekucingeni kwiinjineli ezininzi eziqeqeshelwe ukubala imeko esisigxina. Inzuzo ezinzileyo ikwizinto ezikhutshwayo eziphetshwayo ezivela kwimveliso, ukuthutha, kunye nokufakela iindawo ezitshintshiweyo phantsi komgca.

Kukho i-nuance apha ehlala iphosakele: umgangatho we-threading kunye nokukhuselwa kwe-corrosion. Isilungisi esibambayo sibi ngaphezu kokungenamsebenzi. Sonke siye sadibana nee-turnbuckles ezitshiphu ezitshise zivaliwe emva kobusika obunye, zinika uphawu lwazo oluphambili. Yiyo loo nto kubalulekile ukukhangela abavelisi abakhethekileyo. Umzekelo, kwingingqi efana neYongnian eHebei, elihabhu enkulu yemveliso ekhawulezayo, ugxininiso kwinkqubo kunye nomgangatho wezinto eziphathekayo unamandla ngenxa yokhuphiswano olupheleleyo lwemarike. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esebenza ukusuka kweso siseko esikhulu sokuvelisa, ngokuqhelekileyo sineziseko zokuvelisa i-consident, high-grade threads and coatings-njenge-hot-dip galvanizing-ethintela ukubanjwa. Oku kuthembeka ngumqhubi wozinzo oluthe cwaka.

UkuSebenza kwezinto ngokuSebenzayo kunye nokuPhuculwa koMthwalo

Makhe sithethe ngokusetyenziswa kwezinto eziphathekayo. Kwinkqubo yoxinzelelo lwendabuko olusisigxina, kufuneka ugqithise ngokugqithiseleyo ububanzi beentonga okanye iintambo ukuze uphendule ngokufakela okungagqibekanga okanye ukutshintshwa komthwalo ongabalwanga. Oku akuphumelelanga. I-turnbuckle ikuvumela ukuba ufake isixokelelwano kwaye emva koko ucofe kuxinzelelo oluchanekileyo. Oku kuthetha ukuba icandelo ngalinye kwitsheyini linokulinganiswa ngokuchanekileyo ngakumbi kumsebenzi walo wokwenene, hayi imeko eqikelelwayo eyongeza i-20-30% yezinto ezongezelelweyo. Ndiyibonile le nto kwi-tower guying applications. Ngokusebenzisa i-turnbuckle ukufezekisa uxinzelelo olugqibeleleyo emva kofakelo, sinokuhlala sihlisa i-diameter yentambo ngobungakanani, songa amakhulu eekhilogram zentsimbi kwinqaba nganye.

Olu lungelelwaniso luvuza kwikhonkco lonikezelo. Iimathiriyeli ekrwada encinci zombiwa, amandla amancinci okulungiswa kunye nokuqengqeleka, amafutha amancinci othutho. Yimeko yakudala 'encinci nangaphezulu', kodwa ifuna ukuzithemba ukuba indlela yohlengahlengiso ayizukuba yindawo ebuthathaka. Umgangatho wokwenza kunye noomatshini bomzimba we-turnbuckle kunye neebholithi zawo zibalulekile. Ukusilela apha kuyachasa zonke iinzuzo zethiyori.

Kukho umngeni osebenzayo, nangona kunjalo. Ukuphumeza olu lungiselelo kufuna ufakelo lwezakhono. Umfaki ofaka i-turnbuckle ukuya kumda wokucinga ukuba 'ukuqina kungcono' kunokubangela ukusilela kwangaphambi kwexesha. Uqeqesho luyinxalenye yenxaki ezinzileyo. Akukhona nje malunga nemveliso kwibhokisi.

Ukuququzelela uKwakha kunye nokuSetyenziswa kwakhona

Inkalo yokucinga phambili ngakumbi kuyilo lolwakhiwo (i-DfD). Zingaphi izixokelelwano zezakhiwo ezidityanisiweyo okanye ezigruthiweyo zabekwa endaweni, ezimiselwe itiphu ekupheleni kobomi? Uqhagamshelwano usebenzisa i ibhonti yebhawunti iyancitshiswa ngokwendalo. Kwizakhiwo zexeshana-imigangatho yeqonga, iiholo zemiboniso, iintente zesiganeko-lo mgangatho. Kodwa umgaqo uyangena kuyilo lwesakhiwo esisisigxina. Siphonononga iinkqubo apho ukudibanisa kwesakhiwo kwiiprojekthi zokusetyenziswa kwakhona kugxininiswa ngamaqhosha ajikayo. Xa isakhiwo sidinga ukulungiswa kwakhona kwiminyaka engama-30, loo malungu entsimbi anokuthi akhululwe, agcinwe, kwaye aphinde asetyenziswe kwenye indawo. I-turnbuckle sisitshixo esivula ukuphinda kusetyenziswe loop.

Oku akuyothiyori kuphela. Ndabandakanyeka kwiprojekthi yokudiliza inqaba endala yothutho ukuze kuphuculwe isiporo. I-turnbuckles yokuqala kwiingcingo zomfana, nangona i-rust, yayisasebenza. Emva kokucoca kunye nokuphinda kufakwe i-galvanizing, malunga ne-70% yaphinda yasasazwa kulungelelwaniso olutsha. Umxhasi ugcine iindleko, kodwa okona kubaluleke kakhulu, ikhabhoni equkiweyo kwezo ziqwenga zentsimbi zenziwe zagcinelwa omnye umjikelo wobomi. Leyo yimpumelelo ebonakalayo ezinzileyo.

Umqobo udla ngokuba yi-accounting. Ixabiso lokuqala lenkunzi yenkqubo enokuphinda isetyenziswe, ekumgangatho ophezulu iphezulu. Ukukholisa umnini weprojekthi ukuba ahlawule ngaphezulu ngoku kwiinzuzo zeminyaka engama-30 ngaphandle ngumzabalazo wanaphakade. Kuya kufuneka uyibeke njengokunciphisa umngcipheko kunye nexabiso le-asethi yexesha elizayo, hayi nje isongezo se-eco-feel-good.

Ukomelela kunye nesakhono sokuziqhelanisa

Uzinzo kukwamalunga nokomelela—ukumelana nokothuka ngaphandle kokusilela okuyintlekele. I-turnbuckle inika inkqubo eneqondo 'lokunika' kwaye, ngokubaluleke ngakumbi, indlela yokubuyisela. Emva kwesiganeko esigqithileyo esifana nenyikima encinci yenyikima okanye isaqhwithi, inkqubo exineneyo inokuphuma ngaphandle kwe-spec. Ngonxibelelwano oluzinzileyo, kuya kufuneka uvavanye kwaye unokutshintsha indawo. Ngee-turnbuckles, i-crew inokungena, ilinganise ukuxinezeleka, kwaye uyibuyisele kwiiparamitha zoyilo lokuqala. Ulwakhiwo lubuyiselwa ekusebenzeni ngokugqibeleleyo ngaphandle kwezinto ezintsha.

Oku kulungelelaniswa komthamo kubalulekile kwiziseko ezingundoqo kwiimeko eziguqukayo zemozulu. Qwalasela ibhulorho yeenyawo eneentsimbi zeentsimbi. Ukutshintsha kobushushu kunokuthoba okanye kucinezele kakhulu iintambo. Ukugcinwa rhoqo kunye ne-turnbuckles kulula. Ngaphandle kwabo, imijikelo yoxinzelelo ikhokelela ekudinweni kwiziphelo zetheminali, ezifuna ukulungiswa okudityanisiweyo okanye ukutshintshwa kwentambo epheleleyo kwakamsinyane.

Ivakala ilula, kodwa ingqondo yobunjineli kufuneka isuke ‘kuyilo, ukwakha, ukulahla’ ukuya ‘kuyila, ukwakha, ukubeka iliso, nokugcina.’ I-turnbuckle yimbonakaliso ebonakalayo yaloo ngqondo yesondlo. Yingongoma yongenelelo eyakhiwe kwisakhiwo.

Ikhonkco lonikezelo kunye ne-Localized Production angle

Okokugqibela, ukuzinza kwecandelo ngokwalo kubalulekile. I-turnbuckle ethunyelwe embindini welizwe jikelele isuka kumthengisi wegeneric inophawu olukhulu lwekhabhoni phambi kokuba ifakwe. Apha kulapho ukwenziwa kwasekhaya, ukwenziwa kwezinto ezikhethekileyo kudlala indima. Ukufumana iqela eliphambili lemveliso efana neSithili saseYongnian, apho I-Sunnian Zitai Festener Fishaner Comment Com. isekwe, inokunciphisa imayile zothutho kwiiprojekthi ngaphakathi kwe-Asia, ukuba akunjalo kwihlabathi jikelele. Indawo yabo kufutshane nomzila kaloliwe omkhulu kunye nothungelwano lweendlela (njengeBeijing-Guangzhou Railway kunye ne-G4 Expressway) ayisiyondawo yokuthengisa-iguqulela ukuthoba ukukhutshwa kwezinto ezikhutshwayo zokufumana izibophelelo ezinzima, ezixineneyo kwiindawo zemisebenzi.

Iziseko zemveliso ezidityanisiweyo zikwathanda ukuba nemithombo engcono yokurisayikilisha yentsimbi ecekethekileyo kunye nokusetyenziswa okusebenzayo kwamandla kwiyunithi nganye ngenxa yesikali. Xa undwendwela le mimandla yoshishino, ubona iinkqubo ezivaliweyo zocingo lwentsimbi kunye nentonga. Uzinzo alukho kwincwadana; kukusebenza kakuhle kwenkqubo yezinto eziphilayo apho inkampani efana neZitai iyinxalenye yayo. Basenokungazithengi njengenkampani 'eluhlaza', kodwa imeko yabo yokusebenza iyayinciphisa inkunkuma xa ithelekiswa nemveliso eqhekekileyo, encinci.

Ekugqibeleni, ibhonti yebhawunti iphucula uzinzo kungekuko ngophawu olunye lotshintsho olululo, kodwa ngendibaniselwano yoyilo olukrelekrele oluvumela ubomi obude, ukusebenza kakuhle kwemathiriyeli, ukuphinda kusetyenziswe, kunye nokomelela. Kububungqina bengcamango yokuba ngamanye amaxesha esona sisombululo sizinzileyo seso esikuvumela ukuba ulungise, ulungelelanise, kwaye ulungelelanise, kunokuba ukrazule kwaye ubeke endaweni. Ubuqhetseba buchaza ibakala elifanelekileyo kumenzi oqondayo ukuba ezi zinto azikho nje izinto ezithengiswayo, kodwa izinto ezibalulekileyo, ezichaza ixesha elide. Olo lubizo lomgwebo wehlabathi lokwenyani.
