(1) Ipayipi lokungena kwamanzi: Ipayipi lokungena kwamanzi lethangi lamanzi ngokuvamile lifinyelelwa kusuka odongeni oluseceleni, kodwa futhi kusuka phansi noma phezulu. Uma ithangi lamanzi lisebenzisa ingcindezi yenethiwekhi yepayipi emanzini, ipayipi lokungena kufanele lifakwe ivalvu yebhola elintantayo noma ivalvu ye-hydraulic. Ivalvu yebhola elintantayo ngokuvamile ingabi ngaphansi kuka-2. Ububanzi bevalvu yebhola elintantayo bufana nobepayipi lokungena. Ivalvu ngayinye yebhola elintantayo kufanele ifakwe ivalvu yokufinyelela phambi kwayo. (2) Ipayipi lokungena: ipayipi lokungena lethangi lingaxhunywa kusuka odongeni oluseceleni noma phansi. Iphansi lepayipi lokungena elixhunywe odongeni oluseceleni noma phezulu komlomo wepayipi lokungena elixhunywe phansi kufanele libe phezulu ngamamilimitha angu-50 kunephansi lethangi. Ipayipi lokungena lethangi lamanzi kufanele lifakwe ivalvu yesango. Amapayipi okungena nawokuphuma ethangi lamanzi kufanele abekwe ngokwehlukana. Uma amapayipi okungena nawokuphuma eyipayipi elifanayo, amavalvu okuhlola kufanele afakwe kumapayipi okungena. Uma kudingeka ukufaka ivalvu yokuhlola, kufanele kusetshenziswe ivalvu yokuhlola ejikayo enokumelana okuncane esikhundleni sevalvu yokuhlola yokuphakamisa, futhi ukuphakama kufanele kube ngaphezu kwe-1m ngaphansi kwezinga lamanzi elincane lethangi. Uma abantu abaphilayo nabacimi bomlilo behlanganyela ithangi lamanzi elifanayo, ivalvu yokuhlola epayipini lokukhipha umlilo kufanele okungenani ibe ngaphansi ngamamitha amabili kunephayiphi yesiphoni yamanzi yasekhaya (uma iphansi kunephayiphi, i-vacuum yesiphoni yamanzi yasekhaya izobhujiswa, futhi ukugeleza kwamanzi kuphela okuphuma epayipini lokukhipha umlilo kungaqinisekiswa), ukuze ivalvu yokuhlola icindezelwe ngokucindezela okuthile. Izindawo zokugcina umlilo ziyasebenza ngempela lapho umlilo uqhuma. (3) Ipayipi lokugcwala: ipayipi lokugcwala lethangi lamanzi lingaxhunywa odongeni oluseceleni noma phansi, futhi ububanzi balo bepayipi bunqunywa ngokuya ngokugeleza okuphezulu ethangini lokukhipha, futhi kufanele libe likhulu kunephayiphi lokungena kwamanzi i-L-2. Akukho valvu okufanele ifakwe epayipini lokugcwala. Ipayipi lokugcwala akufanele lixhunywe ngqo nohlelo lokukhipha amanzi. Kumele lisetshenziswe ekukhipheni amanzi ngokungaqondile. Ipayipi lokugcwala kwamanzi kufanele livikelwe othulini, ezinambuzaneni nasezimpukaneni, njengesivalo samanzi kanye nesivikelo sesihlungi. (4) Ipayipi lokukhipha amanzi: ipayipi lokukhipha amanzi ethangini lamanzi kufanele lixhunywe kusukela phansi endaweni ephansi kakhulu. Ithangi lamanzi lokulwa nomlilo kanye netafula lokuhlala lifakwe ivalvu yesango (ivalvu yokuvimba akufanele ifakwe), engaxhunywa nepayipi lokugcwala kwamanzi, kodwa ingaxhunywanga ngqo nohlelo lokukhipha amanzi. Uma kungekho zidingo ezikhethekile, ububanzi bepayipi lokukhipha amanzi ngokuvamile buyi-DN50. (5) Ipayipi lokukhipha umoya: ithangi lamanzi lamanzi okuphuza kufanele linikezwe isembozo esivaliwe, kanti isembozo kufanele sinikezwe imbobo yokufinyelela kanye nepayipi lokukhipha umoya. Umoya unganwetshwa ngaphakathi noma ngaphandle, kodwa hhayi endaweni yegesi eyingozi. Umlomo womoya kufanele ube nesivikelo sesihlungi ukuvimbela uthuli, izinambuzane kanye nomiyane ukuthi bangangeni emhubheni. Ngokuvamile, umlomo womoya kufanele ubekwe phansi. Amavalvu, izivalo zamanzi kanye namanye amadivayisi avimbela umoya akufanele afakwe epayipini lokukhipha umoya. Ipayipi lokukhipha umoya akufanele lixhunywe nohlelo lokukhipha amanzi kanye nomsele wokukhipha umoya. I-snorkel ngokuvamile i-DN50 ububanzi. (6) Igeyiji yezinga: Ngokuvamile, igeyiji yezinga lengilazi kufanele ifakwe odongeni oluseceleni lwethangi ukukhombisa izinga lamanzi endaweni ethile. Uma ubude begeyiji yezinga elilodwa bunganele, amageyiji amabili noma ngaphezulu angafakwa phezulu naphansi. Ukugqagqana kwamageyiji amabili aseduze akufanele kube ngaphansi kuka-70 mm, njengoba kuboniswe kuMfanekiso 2-22. Uma ithangi lamanzi lingenaso isikhathi sesignali yezinga loketshezi, ithubhu yesignali ingasethwa ukuze inikeze isignali yokugcwala. Ithubhu yesignali ngokuvamile ixhunywe odongeni oluseceleni lwethangi, futhi ukuphakama kwayo kufanele kubekwe ukuze phansi kwethubhu kuhambisane nephansi lethubhu yokugcwala noma ubuso bamanzi okugcwala bokugqagqa. Ububanzi bephayiphi ngokuvamile buyiphayiphi yesignali ye-DNl5, engaxhunywa esitsheni sokugeza nasesitsheni sokuwasha egumbini lapho abantu bevame ukusebenza khona. Uma izinga loketshezi lethangi lamanzi lixhumene nephampu yamanzi, i-relay yezinga loketshezi noma isignali ifakwe odongeni oluseceleni noma isembozo esiphezulu sethangi lamanzi. I-relay noma isignali yezinga loketshezi evame ukusetshenziswa ihlanganisa uhlobo lwebhola elintantayo, uhlobo lwenduku, uhlobo lwe-capacitive kanye nohlobo oluyisicaba oluntantayo. Kufanele kugcinwe ivolumu ethile yokuphepha yamazinga amanzi alenga kagesi aphezulu naphansi ethangi lamanzi anomfutho wephampu yamanzi. Izinga lamanzi okulawula kagesi eliphezulu ngesikhathi sokuvalwa kwephampu kufanele libe ngaphansi ngo-100 mm kunezinga lamanzi agcwele, kuyilapho izinga lamanzi okulawula kagesi elincane ngesikhathi sokuqala kwephampu kufanele libe ngaphezulu ngo-20mm kunezinga lamanzi elincane lomklamo, ukuze kugwenywe ukugcwala noma ukugoba ngenxa yamaphutha. (7) Isembozo sethangi lamanzi, isitebhisi sangaphakathi nesangaphandle
