    Amapayipi Okwakheka Kwesigaba Esingenalutho Olayini Wendle

    Amapayipi Esakhiwo Esigaba Esingenalutho Omugqa Wokuhambisa Indle Isithombe Esifakiwe
    • Amapayipi Okwakheka Kwesigaba Esingenalutho Olayini Wendle

    Incazelo emfushane:

    Lokhu kushiwo ukuhlinzeka ngezinga lokukhiqiza lesistimu yamapayipi ukuhambisa amanzi, igesi kanye nowoyela ezimbonini zikawoyela negesi yemvelo.

    Kunamazinga amabili wokucaciswa komkhiqizo, i-PSL 1 ne-PSL 2, i-PSL 2 inezidingo eziyisibopho zokulingana kwekhabhoni, ukuqina kwe-notch, amandla aphezulu wokukhiqiza namandla aqinile.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ngenisa

    Ukusetshenziswa kwamashubhu esakhiwo sesigaba esingenalutho kuye kwashintsha imboni yezokwakha, kwahlinzeka ngezinzuzo eziningi mayelana nobuqotho besakhiwo, ukuguquguquka kanye nokusebenza kahle kwezindleko.Lawa mapayipi afaka izikhala ezingenalutho zangaphakathi zomumo ohlukahlukene, eqinisekisa amandla esakhiwo nokuzinza kuyilapho enciphisa isisindo futhi ethuthukisa ukuguquguquka komklamo.Le bhulogi izocubungula izinzuzo eziningi zamashubhu esakhiwo sesigaba esingenalutho, igqamisa ukubaluleka kwawo kumaphrojekthi wokwakha wesimanje.

    Thuthukisa ubuqotho besakhiwo

     Amapayipi esakhiwo anesigaba esingenaluthozaziwa ngesilinganiso sazo esihle kakhulu samandla nesisindo.Lesi sakhiwo siphumela emumeni wayo ohlukile we-cross-sectional, omelana namandla okucindezela nokugoba.Ngokusabalalisa imithwalo ngokulinganayo, lawa mapayipi anciphisa ingozi yokuguquguquka noma ukuwa ezimweni ezinzima, okuwenza afanelekele amaphrojekthi engqalasizinda abalulekile njengamabhuloho, izakhiwo eziphakeme kanye nezindawo zemidlalo.

    Amandla angokwemvelo wamapayipi esakhiwo anesigaba esingenalutho avumela abaklami nabaklami bezakhiwo ukuthi bakhe izakhiwo ezinezikhala ezinde namandla okuthwala umthwalo, okuholela ezinhlakeni ezibukeka kahle, ezizwakalayo, futhi ezikwazi ukumelana nokuhlolwa kwesikhathi.Ngaphezu kwalokho, ukuzinza kwayo okuhle kakhulu kuyenza ibe ukukhetha okuhle ezindaweni ezithandwa ukuzamazama komhlaba, iqinisekise ukuphepha kwabahlali ezindaweni ezivame ukuzamazama.

    Ukuhlukahluka komklamo

    Enye yezinzuzo eziyinhloko zamapayipi esakhiwo sesigaba esingenalutho ukuguquguquka komklamo wabo.Izinhlobonhlobo zomumo ezitholakalayo, ezifana nonxande, oyindilinga nesikwele, zivumela abaklami bezakhiwo nonjiniyela ukuthi bakhe izakhiwo ezibukeka kahle ezihlangana ngaphandle komthungo nendawo ezizungezile.Ikhono lokuhlanganisa ubujamo nosayizi abahlukene liphinde lithuthukise ukuguquguquka kwedizayini ukuze kuhlangatshezwane nezidingo ezahlukahlukene zanoma iyiphi iphrojekthi.

    Amapayipi esakhiwo sezingxenye ezingenalutho nawo adlala indima ebalulekile ezinkambisweni zokwakha ezisimeme.Imvelo yabo engasindi inciphisa inani lezinto ezidingekayo ukuze kwakhiwe isakhiwo, ngaleyo ndlela kunciphisa umthelela wemvelo.Ukwengeza, i-modularity yabo ivumela ukuhlanganisa nokuhlakazwa kalula, okubenza basebenziseke kabusha futhi banciphise ukukhiqizwa kwemfucuza ngesikhathi sokwakha nokudilizwa.

    Ukusebenza kahle kwezindleko

    Ngaphezu kwezinzuzo zesakhiwo nesakhiwo, amashubhu esakhiwo sesigaba esingenalutho anikeza izinzuzo ezibalulekile zokonga kwezindleko.Isidingo sezinto ezisekelayo sincishisiwe, siqeda isidingo sokuqiniswa ngokweqile, okuholela ekongeni kwezindleko zizonke.Imvelo yabo engasindi futhi yehlisa izindleko zokuthumela, okubenza babe ukukhetha ukonga kwamaphrojekthi ngesabelomali esiqinile.

    Lawa mapayipi aphinde ahlinzekele ukonga izindleko zesikhathi eside ngenxa yokuqina kwawo okuphakeme kanye nezidingo zokunakekelwa okuphansi.Ukumelana kwabo nokugqwala kanye nezici zemvelo kunganciphisa izindleko zokulungisa nokushintshwa kuyo yonke impilo yesakhiwo.Ukwengeza, kulula ukuzifaka, okunciphisa izindleko zabasebenzi, okuvumela ukwakhiwa kuqedwe ngesikhathi.

    Ekuphetheni

    I-ducting yesakhiwo yesigaba esingenalutho ngokungangabazeki iyiguqule imboni yezokwakha, yahlinzeka ngobuqotho besakhiwo obuthuthukisiwe, ukuhlukahluka kwemiklamo kanye nokusebenza kahle kwezindleko.Ngokufinyelela ukulingana okuphelele phakathi kwamandla nesisindo, lawa mapayipi ahlinzeka ngokuzinza okungenakuqhathaniswa kuyilapho evumela abaklami bezakhiwo nonjiniyela ukuveza ubuhlakani babo.Ukwengeza, izakhiwo zabo ezizinzile zifaka isandla ezenzweni zokwakha ezihambisana nemvelo.Njengoba imboni yezokwakha emhlabeni wonke iqhubeka nokuthuthuka, amashubhu esakhiwo sezingxenye ezingenalutho azoqhubeka eyimpahla ebalulekile ekwakheni izakhiwo eziphakeme nezihlala isikhathi eside ezizobhekana novivinyo lwesikhathi.
