Izimo ezimbili zephrojekthi ziphula ukushelelaisondo eligoqayo lomnyangongokushesha kunanoma yikuphi okunye: umoya kasawoti, kanye nokusetshenziswa njalo. Ziya ngokuya zihlangana.
Umkhuba wokwenza izincazelo unomkhuba wokuthwala into phambili kusukela kuphrojekthi yokugcina. Ukuhlanganiswa kwesondo eligoqekayo okwenziwe ngendlela eyamukelekayo ekufakweni kwehhovisi elingaphakathi nezwe kukopishwa ehhotela eliseceleni kolwandle, endaweni yokugibela egudle ugu noma emzileni wesibhedlela - bese kwehluleka phakathi nesikhathi sewaranti. Isizathu akusikho ukuthi ihadiwe yayinephutha. Kungoba iziguquguquko ezimbili zemvelo zashintsha ngesikhathi esisodwa, futhi akukho noyedwa owabhalwa kulokho okucacisiwe.
Zombili lezi ziguquguquko manje sekulula ukuzichaza uma ziqhathaniswa nazo kunangeminyaka eyishumi edlule. Ukuhlolwa komjikelezo kanye nokuhlolwa kokufuthwa ngosawoti kusuke ezintweni ezengeziwe ezingakhethwa kuya ezintweni ze-tender line, futhi amazinga angemuva kwazo abuyekeziwe ukuze abonise imijikelezo yemisebenzi yezentengiselwano kuneyezindawo zokuhlala.
Ingcindezi yezentengiselwano ngemuva kwalolo shintsho iyalinganiswa. Izinhlelo zokushelela ziyaqhubeka nokuhlanganyela ezindaweni zokuhlala nezentengiselwano, futhi ukuzenzakalela kwenezela imijikelezo yemisebenzi phezulu: ukuhlanganiswa kwezinhlelo zeminyango eshelelayo ezenzakalelayo emakhaya ahlakaniphile nasezindaweni zezentengiselwano kubangela cishe ukukhula okungu-20% kwehadiwe yeminyango eshelelayo, ngokusho kwe-Business Research Insights, kuyilapho isidingo esikhulayo sezakhiwo zokonga isikhala sibangela cishe u-35%. Ukuzenzakalela kushintsha umbuzo wencazelo, ngoba umnyango osebenza ngamandla ujikeleza kaningi kakhulu kunowesandla futhi awukwazi ukuthembela kumsebenzisi osiza iphaneli ukuthi ime kancane.
Izindlela ezimbili zokwehluleka, imininingwane emibili ehlukene
Ukuchayeka ogwini kuhlasela izinto zokwakha. Umoya ogcwele usawoti, ukujikeleza komswakama kanye ne-chloride emoyeni kusheshisa ukugqwala kwezingxenye zensimbi, futhi umonakalo ugxila ezindaweni okunzima ukuzihlola: imijaho yamabhere, amaphini e-axle kanye nobuso bokuxhumana kwethrekhi. Ukugoba esondweni elijikelezayo kukhulisa ukungqubuzana, ukungqubuzana kukhulisa amandla okudonsa umqhubi azizwayo, futhi ekugcineni iphaneli iyahudula noma iphume emizileni.
Imoto eningi ihlasela umshini. Iphaneli yokushelela yokuhlala ingagibela izikhathi eziyizinkulungwane ezimbalwa ngonyaka. Umnyango wezohwebo esiteshini sezokuthutha noma esibhedlela ungagibela izikhathi ezingamashumi ezinkulungwane ngesikhathi esifanayo - futhi iminyango ezenzakalelayo iphinda lokho futhi, ngoba uhlelo lokushayela alululazi iphaneli ekumisweni kwayo ngendlela umuntu enza ngayo.
Umphumela osebenzayo: incazelo yogu lolwandle kufanele yakhiwe ngezinto zokwakha kanye nokuqinisekiswa kokumboza, kuyilapho incazelo yogu lolwandle olunezimoto eziningi kufanele yakhiwe ngokusekelwe empilweni yomjikelezo ebhaliwe. Amaphrojekthi agu lolwandle kanye nezimoto eziningi adinga izidingo ezimbili ezihlanganisiwe, hhayi ezihlanganisiwe.
Yimaphi amaphrojekthi asogwini okufanele acaciswe
Ukukhetha okungagqwali, hhayi nje "okungagqwali." Ibanga 304 liyi-default evamile futhi liyanele ezindaweni ezivikelekile zangaphakathi nezwe. Ukuze kubonakale ngqo ogwini, isondo le-roller lensimbi engagqwali ebangeni 316 liyisinqumo esichazwe kabanzi ngenxa yokuqukethwe kwalo kwe-molybdenum kanye nokumelana kwe-chloride okuthuthukisiwe; isondo le-roller elingu-304 kufanele liphathwe njengenketho yangaphakathi nezwe kunokuba kube yi-offshore default. Lapho ihadiwe ihlangabezana nohlaka lwe-aluminium, ama-washer okuhlukaniswa noma i-coating ehambisanayo kufanele ichazwe ukuze kugwenywe izinkinga zombhangqwana we-galvanic ezindaweni zokulungisa.
Isikhathi kanye nendlela yokufafaza usawoti eshiwo. I-ASTM B117 iyindlela yokufafaza usawoti ebhekiselwa kakhulu kuyo; i-ISO 9227 ilingana nomhlaba wonke. Ngokubalulekile, lezi zindinganiso zichaza indlela yokuhlola, hhayi umkhawulo wokudlula - isikhathi sokudalulwa esidingekayo sivela ekucacisweni kwephrojekthi noma endinganisweni yeklayenti. Izigaba ezijwayelekile zokucaciswa zingamahora angu-96, 240 kanye no-500 okudalulwa kwe-ASTM B117, kanye nezikhathi zamahora ayi-1,000 noma ngaphezulu ezivela kumaphrojekthi asogwini naseduze nolwandle. Ukucaciswa kufanele kubize kokubili indlela kanye namahora, kanye nenqubo yokwamukelwa (isibonelo, akukho ukugqwala okubomvu kanye nephesenti eliphezulu lokugqwala okumhlophe).
Izinhlangano ezivalwe kahle, ezigcotshwe kusengaphambili. Ukuphinda ugcobe isondo eligoqekayo ebusweni basogwini akuvamile ukuba wusizo. Izinhlangano ezivalwe kahle ezinesikhathi sesevisi esibekiwe zisusa umsebenzi wokulungisa amaqembu amaningi ezikhungo angakwazi ukuwufeza ngokoqobo.
Yimaphi amaphrojekthi anethrafikhi ephezulu okufanele acaciswe
Idatha yokuhlola impilo yomjikelezo enendlela eqanjwe igama. I-ANSI/BHMA A156.14 isungula izidingo zehadiwe yomnyango eshelelayo negoqekayo futhi ihlanganisa ukuhlolwa komjikelezo, ukulayisha kabi, ukuqina komthwalo oqinile, ukushelela, ukushelelayo okuqinile kanye nokushelelayo okuguquguqukayo. Ukubuyekezwa kuka-2024 kubonisa umkhuba wamanje wehadiwe yokuhlala neyezentengiselwano. Eminyango eshelelayo negoqekayo esebenza ngamandla aphansi, i-ANSI/BHMA A156.38 idinga imijikelezo engu-300,000, enezikhathi zokuvula nokuvala ezigcinwe ngaphakathi kwe-−10% kuya ku-+20% yamanani aqoshwe ekuqaleni kokuhlolwa - imodeli ewusizo yokuthi isimangalo somjikelezo kufanele sifaneleke kanjani.
Isilinganiso somthwalo ngaphezu kwesisindo se-sash esibaliwe. Isondo eligoqayo elisindayo kufanele lichazwe ngomthwalo walo olinganiselwe, hhayi ngelebula ekhasini lekhathalogi.Isondo elijikelezayoIzilinganiso zomthwalo kufanele ziqhathaniswe nesisindo sangempela sephaneli kanye nokucwebezela, ihadiwe kanye nomthwalo womoya ebusweni bangaphandle. Umkhawulo, hhayi okufanayo, yiwona umgomo: isibalo esilinganisiwe kufanele sibe ngaphezu komthwalo wesevisi obaliwe.
Ibanga lokulungisa lishiwo ngamamilimitha. Ama-hangers alungisekayo ukuphakama avumela abafaki ukuthi bamunce i-slab futhi balandelele ukubekezelelana endaweni. Kumaphrojekthi anethrafikhi ephezulu, lokho kulungiswa yikho okuvimbela iphutha lokulungisa kuqala ukuthi lingabi yi-oda lokufaka esikhundleni.
Imigqa eyisithupha ehambisana nayo yonke imininingwane yesondo eligoqekayo
- Izinto zesondo eligoqekayo kanye nezinga (isibonelo, isondo eligoqekayo elingagqwali elingu-316 lezindawo ezisogwini, noma isondo eligoqekayo le-nylon lapho ukusebenza okuthule kubaluleke ngaphezu komthwalo).
- Uhlobo lokuthwala — luvaliwe, lugcotshwe kusengaphambili, lunesikhathi senkonzo esibekiwe.
- Isilinganiso somthwalo ngesondo ngalinye eligoqekayo, kanye nesisekelo sokuhlolwa esitholiwe.
- Isimangalo sempilo yomjikelezo ngendlela yokuhlola efanelekile kanye nenani lomjikelezo.
- Ukucaciswa kokugqwala — indlela ejwayelekile kanye namahora okuchayeka adingekayo kanye nenqubo yokwamukelwa.
- Ukulandelela — izitifiketi zezinto ezisezingeni leqoqo, ezihambisana kakhulu nesheduli yehadiwe ekuthunyelweni kwamathenda.
Lapho izimo ezimbili zihlangana khona
Izinhlobo zephrojekthi ezihlanganisa umoya kasawoti nokusetshenziswa kakhulu zikhula ngokushesha kunanoma yisiphi isigaba sodwa: iziteshi zesikebhe nezokuhamba ngesikebhe, izibhedlela nemitholampilo yasogwini, imigwaqo yezokuthutha yasogwini, iminyango yokungena ezindaweni zokungcebeleka, izindawo zokuthengisa ezisogwini kanye nezindawo zokucwaninga zasolwandle. Kulezi zakhiwo, imininingwane yesondo eligoqekayo kufanele ihlangabezane nezidingo zezinto kanye nesidingo somjikelezo ngesikhathi esifanayo - futhi ingxenye ngokuvamile iwumugqa wokugcina obuyekezwayo kuphakheji yokuthumela kanye nowokuqala ukwenza ucingo lwenkonzo.
Abaklami kumaphrojekthi anjalo baphatha isondo eligoqekayo kanye nethrekhi njengento eyodwa ecacisiwe kunezinto ezimbili zekhathalogi, ngoba izindlela zokwehluleka ziyasebenzisana: ukugqwala kuphakamisa ukungqubuzana, ukungqubuzana kusheshisa ukuguguleka, futhi ukuguguleka kunciphisa isikhathi ngaphambi kokulungiswa okulandelayo.
Lapho imininingwane ivame ukungahambi kahle khona
Iphutha elivame kakhulu ukwamukela isimangalo sokuhlolwa ngaphandle kwendlela engemuva kwaso: "ukugqwala okuhlolwe" kanye "nokuhlolwa komjikelezo" akusho lutho ngaphandle kokuthi kuchazwe indinganiso, ubude kanye nenqubo yokwamukelwa. Esesibili ukucacisa amasondo e-roller ngaphandle kwethrekhi kanye ne-hanger asebenza kuyo - isondo le-roller eliphezulu kuthrekhi elingabekezeleli ukuthambekela lizoqhubeka nokuguga ngokungalingani. Esesithathu ukuphatha amaphrojekthi asogwini kanye nalawo anabantu abaningi njengezigaba ezihlukene lapho uhlobo lwephrojekthi olukhula ngokushesha luyizo zombili.
Iphuzu elibalulekile
Kumaphrojekthi asogwini kanye nalawo anabantu abaningi abasebenzisa izimoto,isondo elijikelezayoakuyona into yomugqa wezimpahla. Yingxenye lapho izimo ezimbili zesayithi ezinzima kakhulu zihlangana khona, futhi yingxenye eshibhile kakhulu yokuhlanganiswa ukuyicacisa ngokweqile futhi ebiza kakhulu ukuyishintsha — ukwehluleka kwesondo eligoqekayo emnyango onabantu abaningi ogwini akuvamile ukuphela njengokushintsha kwesondo eligoqekayo; kuphela njengokushintshana okuphelele kokuhlanganiswa. Ibanga lezinto zokubhala, indlela yokuhlola, amahora okuvezwa kanye nomjikelezo kubalwa kumanani encazelo kubiza isigaba. Ukuzishiya ngaphandle kubiza isimangalo sewaranti.
