Ama-Wellpoints e-Steel angasetshenziswanga

Izakhiwo zensimbi eziphinda zisebenze njengezixazululo ezibalulekile zokukhipha amanzi emhlabeni kumaphrojekthi wokwakha izisekelo ezijulile kanye nobunjiniyela bezinhlelo zendawo lapho ukulawula amanzi angaphansi emhlabathini kubalulekile ukuze kwakhiwe ngokuphepha nangempumelelo. Lezi ziwellpoints ezincane, ngokuvamile eziqhamuka no-1.25 kuya ku-2 inches ububanzi, zenziwe ukuze zehlise izinga lamanzi angaphansi futhi ziqondise ukucwila ezinhlelweni eziphakeme zokuqhubeka. Izikhwama zensimbi zikhombisa ukuhlala kahle nokuphila isikhathi eside uma kuqhathaniswa nezinto ezikhethwayo, okwenza kube nenzuzo kwezomnotho kubathengisi abenza amaphrojekthi amaningi adinga izinhlelo zokukhipha amanzi ezikhashana. Umklamo ophindayo unciphisa ukulahleka kwezakhiwo ngenkathi wehlisa izindleko zephrojekthi ngokuvumela ukuthi imishini isetshenziswe ezindaweni eziningi phakathi nezikhathi zayo zokusebenza. Emsebenzini wezisekelo ezijulile, kuhlanganisa ukushaywa kwamapayipi, ukufakwa kwezikhwama, nokwakhiwa kwe- cofferdam, ukukhipha amanzi kwe-wellpoint kuvinjelwa ukungena kwamanzi angaphansi, kuqinisa odongeni lokumba, futhi kuvikele izakhiwo ek Pressure hydraulic nasekuphahlazeni okuphansi. Ukufakwa kwamazamu ensimbi kuhilela ukufakwa okuvundlile noma okwenziwayo emhlabeni ophothwe, kuhlanganisa izinhlanga, izimpande, ne-gravels ezincane, lapho sebenza njengamaphuzu okuqoqwa kohlelo lokukhipha amanzi olubanzi. Uma sehlongozwa, ama-wellpoints axhunywa kumkhono ophakathi, ophuma emgqeni, owanele ukusiza uphampu lwe-centrifugal noma olungena emanzini oluhamba kahle nokuqhubeka. Lezi zinhlelo zenza umjikelezo wezinsizakalo ezijulile phakathi kwamafaneli we-wellpoint, zikhululeka ngokweqile ekwehliseni izinga lamanzi, futhi zinikezela ngezimo zokusebenza ezizinzile emsebenzini wokushaya amapayipi, ekumbeni, nakwakhiweni kwezisekelo. Le ndlela ibaluleke kakhulu kumaphrojekthi wezindlela zasemadolobheni, ezokwakha izitimela nezindlela ezisemadolobheni, kanye nomsebenzi wezokwakha lapho amanzi angaphansi ebonisa izinselele ezinkulu emisebenzini yokwakha nokuzinza komhlaba. Izikhwama zensimbi zisebenza kahle ezindaweni ezihlukahlukene zembewu nezimo zokugcina amanzi, ukusuka ezihlahleni ezimhlophe ukuba kubude bamatshe abukhoswe. Abaklami bakhetha isikhala se-wellpoint kanye nemithombo yokuphumpa ngokusekelwe ekudluliseni kwembewu, ukuphakama kokungakabikho kwegcwele, udinga ukuphakanyiswa kobude, nokuhamba kwesikhathi kwephrojekthi. Ubulukhuni bensimbi obuphindayo buphila izingozi zemishini zokufaka kabusha, ukwelashwa kokuhlanzeka, kanye nokuphathwa ezindaweni zokwakha ezisebenzayo. Le mishini ihlanganyela kahle nezinye izindlela zokukhipha amanzi ezisekelo, kuhlanganisa imithombo ejulile, ukumpshayi, nezinhlelo zokukhodla, okuvumela abenjiniya ukuthi bakhe izinqubo zokukhipha amanzi ezihlanganisiwe ezimweni ezithile ezinzima. Ukujula nobuhlakani bokwakha kwezimbobo zensimbi eziphephethwe kusiza kakhulu emanxiwini emhlabeni, ikakhulukazi kumaphrojekthi adinga ukulawula okwamanje amanzi angaphansi ngesikhathi sokufakwa kwamapayipi, ukwehliswa kwezikhwama, imisebenzi yokufaka ama-underpinning, nokumba okuvinjiwe. Ngokugcina izimo zomhlaba ezizinzile futhi wehlisa ingcindezi ye-hydrostatic ezakhiweni, izinhlelo zokukhipha amanzi kwe-wellpoint zikhuthaza ngokuqondile ukusebenza okuphephile, okusheshayo, nokonga kakhulu emsebenzini wezisekelo ezijulile kumkhakha wezokwakha emhlabeni jikelele.
