Izinhlanga namakhanda

Endabeni yokwakha izisekelo ezijulile kanye nezobunjiniyela bokwandisa, ama-wellpoint kanye nezihloko zibalulekile kumasistimu amanzi we-wellpoint, edlala indima ebalulekile ekuphatheni amazinga amanzi phansi ngesikhathi sokuhlasela nokwakha. Le masistimu aklanyelwe ngokukhethekile ukuhambisa amanzi phansi, akhombisa indawo yokusebenza eyomile nezinhlonhlo ezijulile, njengezikhala zepayipi, ukuhlakulela, kanye nokuthuthukiswa komhlaba. Ama-wellpoint iwuphu oluncane olunezikhala ezibomvu ezibekwe ngendlela eqondile emhlabeni ukuze akhweze amanzi phansi aye phezu, kuyilapho izihloko zisebenza njengendawo yokuhlanganisa amanzi akhishiwe ama-wellpoint, kulula ukuphatha ukuhamba kwamanzi nokuhlanza. Ukusebenza kwama-wellpoint nezihloko kusekelwe phezu kwemigomo ye-hydraulic gradient kanye ne-suction. Lapho ama-wellpoint efakwa ezindaweni zokwakha, kudalwa isikhala esingapheli ngenxa yephampu exhunywe kuhullum, okwenza amanzi ahambe emhlabathini owasakazwayo aye kuma-wellpoint. Amanzi aqoqiwe alandela ku-pipe ye-header ukuya endaweni yokukhipha, ekhuphula amazinga amanzi futhi ivumela izimo zokuhlakulela ezomile. Le nqubo yokukhaphula amanzi ibalulekile hhayi kuphela ekugcineni ukuphepha kwezakhiwo kodwa futhi ekugwemeni ukungazinzi komhlaba, okungaholela emiphumeleni engabizi nezinkinga zokwakha. Izicelo ezisemqoka zama-wellpoint nezihloko zifaka phakathi ukusebenziseka kwazo ekuhlakuleleni izisekelo, ekudayisweni, nasekupheleni kwezimoto, lapho amanzi phansi ehlangabezana nengozi enkulu ekwakheni indawo. Ziphinde zisetshenziselwe ezindaweni ezinezingxenye zamanzi eziphakeme, lapho izindlela zokukhulula amanzi ezivamile zingase zingahluleki. Ukuvikelwa kanye neziphumo eziphumelelayo zama-wellpoint nezihloko kukwenza zibe zibalulekile kubakhiqizi abachitha isikhathi ezinkampanini ezibandakanyeka emsebenzini wezisekelo ezijulile, njengalabo abahileleka emapeyipini, ama-cassion, nasemagqumeni akhukhuliwe. Ngaphezu kwalokho, le masistimu ivame ukusetshenziswa kuma-projekthi wokuhlanzwa kwemvelo, lapho ukuphathwa kokuhamba kwamanzi phansi kubalulekile ukuze kuqinisekiswe ukuphepha kwesayithi kanye nokuhambisana. Izincazelo ezivamile zama-wellpoint nezihloko zifaka phakathi izinto eziphuzi, ezivame ukuba zingu-2 kuya ku-4 inches, nezinketho zokwakha ezifana ne-PVC noma insimbi, ngokuya ngalesi sicelo esithile kanye nezimo zomhlaba. Ukuklanywa kwamasisitimu we-wellpoint kungafaneleka nokubaluleka kwesikhala, ubude, kanye nesikhumbuzo sephampu ukuze kukhuphule ukusebenza. Lapho ukhetha ama-wellpoint nezihloko, abalimi kufanele bacabangele izinto ezifana nohlobo lomhlaba, izimo zamanzi phansi, usayizi wephrojekthi, kanye nesilinganiso sokukhulula amanzi esidingekayo. Ngaphezu kwalokho, ukuqonda ukuhambelana kokusebenza nezimo zendawo ezikhona kubalulekile ukuze kuqinisekiswe ukufakwa kahle nokusebenza. Ekuphetheni, ama-wellpoint nezihloko ziwusizo obalulekile kumathuluzi wezobunjiniyela bokwakha izisekelo ezijulile kanye nezobunjiniyela bokwandisa. Ikhono lazo lokuphatha amazinga amanzi phansi ngokuphumelelayo akhulisa ukuphepha nokuzinza kwemisebenzi yokwakha kepha futhi kufaka isandla empumelelweni yaphakade kumaphrojekthi anzima obunjiniyela. Ngokutshalwa kwemali kumasistimu amanzi we-wellpoint asezingeni eliphezulu, abalimi bangaqinisekisa ukuthi bazinikele ngokuphelele ukuhlangabezana nezinselelo zokuphathwa kwamanzi phansi kumaphrojekthi abo, okugcina kuholela ekuphothulweni kwephrojekthi ngesikhathi nangempumelelo.
