Umphezulu Ukugqiba

Iqela leNsimbi yasebukhosiniibonelela ngoluhlu olupheleleyo lweendlela zonyango zokuthintela ukugqwala ezenziwe ngokwezifisoIipayipu zentsimbi ze-ASTM A500, egubungela ukusetyenziswa okuqhelekileyo ngaphakathi elizweni kunye neendawo ezirhabaxa zaselwandle, ezikude nolwandle kunye nezingaphantsi komhlaba. Sinikezela ngeendlela zokugquma eziguquguqukayo ukuze zihambelane nohlahlo-lwabiwo mali olwahlukeneyo lweprojekthi kunye neemfuno zobomi benkonzo.

1. Umphezulu weNtsimbi emnyama
Ukugqitywa kwentsimbi emnyama yokuqala akunazo ezinye izinto ezifunekayo, kudityaniswe nonyango oluqhelekileyo lokulwa nomhlwa olufakwe ioyile. Lukhetho olungabizi kakhulu, lufanelekile kwiiprojekthi zokwakha zangaphakathi, imisebenzi yolwakhiwo lwangaphakathi kunye nezinto ezifuna ukusika okwesibini, ukuwelda kunye nokulungiswa kwakhona. Olu kugqitywa lubonelela ngokusebenza okuzinzileyo okusisiseko kwaye luhlangabezana neemfuno zokusetyenziswa kwexesha elifutshane kokulwa nomhlwa kunye nolwakhiwo lobunjineli besiseko esiqhelekileyo.

2. Ukwaleka kwe-Fusion Bonded Epoxy (FBE)
I-FBE coating lunyango olukhuselayo olusebenza kakuhle olusetyenziswa ngobuchule kwiindawo zemibhobho yentsimbi. Iqhayisa ngozinzo olubalaseleyo lweekhemikhali, imelana ngempumelelo nokukhukuliseka okuvela kwi-asidi, i-alkali, ityuwa kunye nezinye izinto ezahlukeneyo zeekhemikhali. Ngamandla okubopha aqinileyo kunye nokumelana okuhle kokukrweleka, olu phawu lubonelela ngokhuseleko oluhlala ixesha elide lokulwa nokugqwala, olufanelekileyo kwiindawo zoshishino, kwiimeko zokunxibelelana kweekhemikhali kunye nezakhiwo zesiseko esingaphantsi komhlaba ezineemfuno ezingqongqo zokuqina.

3. Ukwaleka okuchasene nokugqwala kwe-3PE Multi-Layer
Ingubo edityanisiweyo ye-3PE enezintlu ezintathu sisisombululo esiphambili sokulwa nokugqwala kwiimeko zobunjineli ezinzima, esenziwe yinkqubo yobugcisa yesakhiwo esinezintlu ezintathu: umaleko we-epoxy primer, umaleko ophakathi wokuncamathelisa kunye nomaleko wokukhusela we-polyethylene wangaphandle. Uyilo lwesakhiwo oludibeneyo lufezekisa indibaniselwano egqibeleleyo yokumelana nokugqwala kweekhemikhali, ukumelana nempembelelo yoomatshini kunye nokusebenza kokuthintela ukungena kwamanzi.
Ngenxa yokuziqhelanisa kwayo kakuhle neemeko ezimaxongo, inkqubo yokugquma ye-3PE yamkelwe ngokubanzi kubunjineli benxweme, izakhiwo zaselwandle, iiprojekthi zesiseko solwandle, kunye nemisebenzi yenqwaba yemibhobho efihliweyo eneemfuno eziphezulu zokulwa nokugqwala kunye nobomi benkonzo ende.

Isicelo Esiphambili

1. Iziseko zoDonga oluseMgangathweni:Ukwakhiwa komhlaba phantsi kwezakhiwo eziphakamileyo, iifektri, iindawo zokugcina impahla, izakhiwo zorhwebo nezindlu zokuhlala. Iziseko zeenqwaba (zonke iintlobo zokwakha izakhiwo).

2. Iziseko zeBridge Pile:Iziseko ezithwele iibhulorho zeendlela ezinkulu, iibhulorho zikaloliwe, kunye nee-viaducts zasezidolophini. Iziseko ezithwele iibhulorho zomlambo, ichibi kunye neebhulorho zolwandle.

3. Ukwakhiwa kweZibuko:Isiseko sokuthwala imithwalo seetheminali zezibuko, iiyadi zeenqanawa kunye neepleyiti zezibuko. Izixhobo ezinzima kunye neenkonzo zokuhanjiswa kwemithwalo yezibuko.

4. Iiprojekthi zoBunjineli boMbane woMoya noLwandle oluPhesheya:Iziseko zeeturbine zomoya ezikude nolwandle. Uyilo lwenkxaso yamaqonga akude nolwandle, iipayipi ezikude nolwandle, iipayipi ezikude nolwandle, iindonga zolwandle kwaye okwangoku Kwizindlu zokuhlala Ukumelana namaza, ukumelana namaza, kunye nokugqwala kolwandle.

5. Ubunjineli Bokwakha Obukhulu:Iziseko ezinzima ezineenqwaba ezibanzi zomsebenzi wobunjineli bokwakha obukhulu (amadama, izitishi zesitimela esingaphantsi komhlaba, kunye neetonela). Inkxaso yoomatshini bemizi-mveliso kunye nemithwalo yezakhiwo.

Ukupakisha kunye nokuHanjiswa

Ukupakisha oku-1:Iintambo zentsimbi ukuze kube lula ukuziphatha Iibhloko zomthi okanye i-dunnage zifakwa phakathi kweenqwaba ukuthintela ukutshintsha kwezitho ngelixa kusenziwa inkqubo yokuthunyelwa. Unyango lomphezulu (ukhetho): Ukupenda okumnyama, ioyile yokuthintela umhlwa, ifilimu yeplastiki. Iinqwaba ze-galvanized zingasongelwa kwifilimu yeplastiki yokukhusela yexeshana ukuthintela ukukrwela umphezulu. Kukho upakisho olwenziwe ngokwezifiso.

2 Ulwazi lokuHanjiswa:Ubude obuqhelekileyo obukhoyo: 6m, 12m. Ubude: obuqhelekileyo nobuqhelekileyo. Ziza noLoliwe lwaseLwandle kunye nokusetyenziswa kwendlela. Zilungele ukuthutha ngolwandle, ngololiwe okanye ngemoto, zikwanamandla ngokwaneleyo xa zisetyenziswa endleleni. Ixesha lokuhambisa liphakathi kweentsuku ezili-15-30 emva kokufumana intlawulo, kuxhomekeke kubungakanani kunye neenkcukacha. Zisebenza ekuthumeleni impahla kwamanye amazwe kwihlabathi liphela, kunye noxwebhu olupheleleyo (Isatifikethi sovavanyo, Uluhlu lokupakisha, iBill of Lading).

3 Amanyathelo okuphatha:Musa ukusebenzisa izilingi okanye iihoko ezingenazo iipadi ukuze udibane ngqo nomphezulu wombhobho nto leyo enokubangela ukuguguleka kombhobho. Gcina kwindawo epholileyo, eyomileyo nengena umoya kakuhle. Ukuze uphephe ukugqwala ngaphambi kokufakwa. Imithwalo emikhulu nenzima kakhulu kufuneka ilandele imigaqo yokuthunyelwa kwempahla yasekuhlaleni.
