Isimiso Esiyinhloko: Kusukela Kungxenye Kuya Kuhlelo
1. Indlela Izindinganiso ze-BPE Ezichaza Ngayo “Ukungakwazi Ukukhipha Amanzi"
“Ukungakwazi ukudonsa amanzi” akuyona ipharamitha eyodwa; kuyisethi yezindlela zokusebenza ezichazwe ezindinganisweni eziningana. Izincazelo ezibalulekile zifaka:
a) Ukusebenza Komsinga
b) Ubuqotho Besakhiwo kanye Nempilo Yenkonzo
c) Ukuqina Kwamanzi
d) Ukuqina Nokumelana Namakhemikhali
2. Indlela Lezi Zimiso Ezilawula Ngayo Ukwakhiwa Kwesistimu
a) Indlela Yokuklama Inqunyiwe
b) Ukukhethwa Kwezinto Ezibalulekile Kusekelwe Emsebenzini
c) Uhlelo Lungaphezu Kokuba Yipayipi Nje
Izindinganiso ze-BPE zifaka ngokusobala ezinye izinto ezibalulekile zesistimu, okwenza zibe yingxenye yomklamo:
· Ama-Manhole nama-Chamber (BS EN 1917, BS EN 13598): Lawa akuzona nje “izindawo zokufinyelela.” Izindinganiso zichaza ukwakheka kwazo, ukusebenza kwe-hydraulic (ukuqinisekisa ukuguquka kokugeleza okubushelelezi), kanye nendima yazo njengama-system node okuhlola, ukuhlanza, kanye nokushintsha indlela. Umklamo kumele uqinisekise ukuthi iziqondiso ze-manhole benching zigeleza kahle futhi azibi yisithiyo se-sediment.
· Imisele kanye Nemibhede: Ipayipi kanye nomhlabathi kuyisakhiwo esihlanganisiwe. Izindinganiso ezifana ne-BS EN 1610 (Ukwakhiwa Nokuhlolwa Kwamapayipi Namanzi Angcolile) zichaza ukufakwa. Umklamo kumele uchaze isigaba semibhede (isb., Isigaba A, B, S) kanye nezinto zokugcwalisa eceleni. Ukukwazi kokukhipha amanzi ohlelweni kuncike kwikhwalithi yendawo ezungezile ehlanganisiwe njengoba kunjalo ngamandla epayipi ngokwalo.
· Ukuhlola Nokugunyazwa: Umklamo awuqediwe kuze kube yilapho uhlanganisa uhlelo lokuhlola. Izindinganiso zithi uhlelo kumele ludlule ku:
· Ukuhlolwa Kokucindezela Komoya noma Kwamanzi: Ukuqinisekisa ukuqina kwamanzi.
· Ukuhlolwa kwe-Mandrel: Kumapayipi aguquguqukayo, i-mandrel (i-go/no-go gauge) iyadonswa ukuqinisekisa ukuthi ipayipi alizange lishintshe ukwakheka kwalo ngaphezu komkhawulo womklamo walo ngesikhathi sokufakwa, okuqinisekisa ukuthi amandla e-hydraulic ayagcinwa.
· Ukuhlolwa kwe-CCTV: Ukunikeza irekhodi eliyisisekelo nokuqinisekisa ukuthi ukufakwa kuyahlangabezana nezinga lomsebenzi odingekayo ukuze kukhishwe amanzi isikhathi eside.
Isiphetho: Umphumela Ophelele
Uhlaka lwe-BPE luhambisa incazelo yokukwazi ukudonsa amanzi ngale kwe-binary ethi “ingabe kuyageleza?” iye kusethi yezindlela eziyinkimbinkimbi nezilinganiswayo: umthamo we-hydraulic, ubuqotho besakhiwo, ukuqina kwamanzi, ukuqina, kanye nokugcinwa.
Ngenxa yalokho, ukwakheka kohlelo ngaphansi kwalezi zindinganiso kuyinqubo enezigaba eziningi, ehlanganisa imikhakha eyahlukene. Kudinga ukuthi unjiniyela, umcacisi, kanye nosonkontileka bacabangele ipayipi, uhlelo lokuxhuma, umbhede, indawo yokugcwalisa, ama-manhole, uhlelo lokuhlola, kanye nokugcinwa okuhlosiwe njengezingxenye ezincikene zesistimu eyodwa eklanywe ngobunjiniyela. Umgomo awusekho nje ukufaka ipayipi, kodwa ukuletha impahla yokukhipha amanzi eqinisekisiwe, eqinile, futhi eqhubekayo esebenza njengohlelo impilo yalo yonke yokuklama.
Lo mbono "ongale kwepayipi" yiwona ohlukanisa ubunjiniyela bamanzi banamuhla, obusekelwe ezindinganisweni nokufakwa kwamapayipi okulula.
