Umbhobho wentsimbi emdaka: Ukuqonda ukuguquguquka kwamaxabiso kwimarike

Umbhobho wesinyithi othuliweyo(ipayipi ye-DI) yinxalenye ebalulekileyo yeeprojekthi zeziseko zophuhliso. Imibhobho yamanzi yentsimbi exutyiweyo kunye nemibhobho yamanzi amdaka yentsimbi exutyiweyo ibaluleke kakhulu ekunikezelweni kwamanzi kunye nolawulo lwamanzi amdaka. Kodwa ixabiso lemarike lale mibhobho, njengexabiso lemibhobho yentsimbi exutyiweyo eyi-150mm, lihlala litshintsha. Izinto ezininzi ezinxulumene noko zibangela olu tshintsho lwamaxabiso.
Ixabiso lezinto eziluhlaza yeyona nto iphambili. Amaxabiso e-iron ore, i-scrap metal, kunye ne-coke achaphazela ngokuthe ngqo iindleko zemveliso. Abangela ngaphezulu kwe-38% yotshintsho lweendleko. Xa amaxabiso ezi zinto enyuka, abavelisi benza abathengi bahlawule ngaphezulu. Umzekelo, ukunyuka kwakutshanje kwexabiso le-Imibhobho yentsimbi ethambileyo eyi-150mmkwakubangelwa kukunyuka kwexabiso lentsimbi yehagu.
Iinkcukacha zemveliso nazo zinempembelelo enkulu. Ububanzi beumbhobho we-ductile, ubukhulu bodonga (njengodidi lwe-K9), ukulinganiswa koxinzelelo, kunye nonyango olukhethekileyo olufana neengqiniba zesamente kwiipayipi zomsele okanye ukugqwala - ukufakelwa okuxhathisayo konke kwenza ixabiso libe phezulu. Ixabiso leepayipi zesinyithi ezithambileyo ze-150mm linokwahluka malunga ne-5% ngenxa yezi mpawu. Iipayipi ezineendonga ezityebileyo okanye ukulinganiswa koxinzelelo oluphezulu zibiza kakhulu.

Ulungelelwaniso lokubonelela ngeenkonzo kunye nemfuno kwimarike luchaphazela iindlela zamaxabiso zexesha elifutshane. Xa kukho iiprojekthi ezininzi zeziseko zophuhliso okanye imisebenzi yokuhlaziya kamasipala, imfuno yeepayipi ezithambileyo iyanyuka. Kodwa ukuba kukho iingxaki kwikhonkco lokubonelela ngeenkonzo, njengokuvalwa kweefektri okanye ukunqongophala kwabasebenzi, ukubonelela ngeenkonzo kuyehla. Kwakhona, ukhuphiswano oluvela kwiipayipi zePVC okanye zeHDPE lunokwenza ixabiso leepayipi zesinyithi ezithambileyo libe phantsi kwiiprojekthi apho ixabiso lixhalabisa kakhulu.
Iindleko zothutho nazo zibalulekile. Iipayipi zentsimbi ezithuthwayo zinzima, ngoko ke ukuzithumela kubiza kakhulu, ingakumbi xa zithunyelwa kude okanye kude. Ezi ndleko zongezwa kwixabiso lokugqibela.
Ukuba abachaphazelekayo bayayiqonda le miba, banokujongana nemarike yemibhobho yesinyithi eguquguqukayo ngokufanelekileyo. Olu lwazi lubanceda benze izigqibo ezingcono xa bethenga okanye bethengisa imibhobho yesinyithi eguquguqukayo. Banokuqikelela utshintsho lwamaxabiso baze bacebe iiprojekthi okanye amashishini abo ngokufanelekileyo. Umzekelo, ukuba bayazi ukuba amaxabiso ezinto eziluhlaza anokunyuka, banokuthenga imibhobho kwangaphambili. Okanye ukuba bangumvelisi, banokulungisa imveliso yabo ngokusekelwe kwimfuno yemarike kunye nemeko yokubonelela. Ngokubanzi, ukuqonda ezi zinto kubalulekile kwimpumelelo kwimarike yemibhobho yesinyithi eguquguqukayo.
