    Yazisa

    Ukusetyenziswa kweetyhubhu zesakhiwo secandelo elingenalutho kuye kwaguqula ishishini lokwakha, libonelela ngeendlela ezininzi zeenzuzo ngokubhekiselele kwingqibelelo yesakhiwo, ukuguquguquka kunye nokusebenza kakuhle kweendleko.Le mibhobho ibonisa izithuba zangaphakathi ezingenanto zeemilo ezahlukeneyo, ziqinisekisa amandla okwakhiwa kunye nokuzinza ngelixa unciphisa ubunzima kunye nokuphucula ukuguquguquka koyilo.Le bhlog iya kukhangela kwiingenelo ezininzi zeetyhubhu zesakhiwo secandelo elingenanto, igxininisa ukubaluleka kwazo kwiiprojekthi zokwakha zanamhlanje.

    Yandisa imfezeko yesakhiwo

     Imibhobho yolwakhiwo lwecandelo elinomngxumazaziwa ngomlinganiselo wazo obalaseleyo wokomelela kubunzima.Le propati iphumela kwimilo yayo ekhethekileyo ye-cross-sectional, echasene nemikhosi yoxinzelelo kunye nokugoba.Ngokuhambisa imithwalo ngokulinganayo, le mibhobho inciphisa umngcipheko wokuguqulwa okanye ukuwa phantsi kweemeko ezinzima, okwenza ukuba zilungele iiprojekthi zeziseko ezingundoqo ezifana namabhuloho, izakhiwo eziphakamileyo kunye neendawo zemidlalo.

    Amandla endalo emibhobho yesakhiwo yecandelo elingenamngxuma ivumela abaqulunqi kunye nabayili bezakhiwo ukuba benze izakhiwo ezinobude obude kunye nekhono eliphezulu lokuthwala umthwalo, okukhokelela kwizakhiwo ezikhangelekayo, ezivakalayo, kwaye zikwazi ukumelana novavanyo lwexesha.Ukongeza, ukuzinza kwayo okugqwesileyo kuyenza ibe lukhetho olufanelekileyo kwiindawo ezithandwa yinyikima, iqinisekisa ukhuseleko lwabahlali kwiindawo ezithandwa ziinyikima.

    Ukusebenza kweendleko

    Ukongeza kwiinzuzo zesakhiwo kunye noyilo, iityhubhu zesakhiwo secandelo elingenanto zibonelela ngeenzuzo ezibalulekileyo zeendleko.Imfuno yezinto ezixhasayo iyancitshiswa, isusa imfuno yokuqiniswa ngokugqithiseleyo, okukhokelela ekugcinweni kweendleko ngokubanzi.Ubume bazo obukhaphukhaphu bukwanciphisa iindleko zokuthumela ngenqanawa, nto leyo ebenza ukuba bakhethe ngokwezoqoqosho kwiiprojekthi kuhlahlo lwabiwo-mali oluqinileyo.

    Le mibhobho inikezela ngakumbi ukonga iindleko zexesha elide ngokuhlala kwayo okuphezulu kunye neemfuno zokugcinwa okuphantsi.Ukuchasana kwabo kwi-corrosion kunye nemiba yokusingqongileyo kunokunciphisa iindleko zokulungisa kunye nokutshintsha ubomi bonke besakhiwo.Ukongezelela, kulula ukuyifaka, okunciphisa iindleko zomsebenzi, ukuvumela ukwakhiwa kugqitywe ngexesha elifanelekileyo.

    Ukuququmbela

    Inxalenye engumgongxo edityanisiweyo iguqule ushishino lokwakha, ibonelela ngentembeko yesakhiwo esomeleziweyo, ukuguquguquka koyilo kunye nokusebenza kakuhle kweendleko.Ngokufezekisa ukulingana okugqibeleleyo phakathi kwamandla kunye nobunzima, le mibhobho inika uzinzo olungenakulinganiswa ngelixa ivumela abakhi bezakhiwo kunye neenjineli ukuba babonise ubuchule babo.Ukongeza, iipropathi zabo ezizinzileyo zinegalelo kwimisebenzi yokwakha ehambelana nokusingqongileyo.Njengoko ishishini lolwakhiwo lwehlabathi liqhubeka nokuvela, iityhubhu zezakhiwo ezingenanto ziya kuqhubeka ziyinto ebalulekileyo ekwakheni izakhiwo ezikumgangatho ophezulu nezihlala ixesha elide eziya kumelana novavanyo lwexesha.
