Iziphampu Zokuphakela Ngemfucuza

Amabhompu aphezulu wokuhlinzeka ngosizo abalulekile emithonjeni ethuthukisiwe yokukhipha amanzi, ikakhulukazi asebenza njengomthombo wamandla wokufaka imithombo ye-eductor noma ye-ejector. Lawa mabhompu akhethekile anikezela ngamanzi aphakanyiswe noma umoya ohlangene kumazinga okuhamba kontrolwe ukuze kudalwe ukusukuma okudingekayo kokukhishwa kwamanzi angaphansi emisebeni yokwakha ezinzulwini nasemikhakheni yesayensi yezakhiwo. Asebenza ngesisekelo somfutho ohlukile, amabhompu aphezulu wokuhlinzeka avumela ama-eductor ukuthi akhiphe amanzi ngempumelelo ezindaweni lapho izindlela ezivamile zokuphumpa zikhombisa ukuthi zinciphile noma zingafaneleki. Amabhompu agcina umfutho wokuphuma ophakeme kanye nenani, okuthinta ngqo ukusebenza kahle kokukwazi kokuphakanyiswa kwendlela ye-eductor kanye nesivinini lapho amanzi angaphansi angakhishwanga ezindaweni zokuthola nezindawo zokufaka ama-pile, kanye nezakhiwo eziphansi. Ukufakwa nokusebenza kwamabhompu aphezulu wokuhlinzeka ngaphakathi ezinhlelweni ze-eductor kudinga ukuhlaziywa okunakekelwe kwemfuno zemvelo ze-hydrogeological, okuhlanganisa ukungena komhlabathi, izinga lokuhamba kwamanzi angaphansi, kanye nezimfuneko zempilo ye-piezometric. Abakhiqizi kufanele bakhethe ukucaciswa kwamabhompu ngokuya ngaphezu kokushoda okudingekayo, ukudlulwa kwamanzi, kanye nokunciphisa kwezinga le-piezometric okudingekayo ukuze kusebenze ngokuphepha emsebenzini wokwakha izisekelo. Amabhompu aphezulu wokuhlinzeka asetshenziswa ngokuhlanganyela namakhanda e-eductor kanye nezinsiza ze-venturi ukuze kudaleke imiphumela yokusukuma endaweni ethile ethatha amanzi ezindaweni ezijulile nezinto ezihlangene lapho izinhlelo ze-well-point ezijwayelekile zinemiphumela emincane. Amabhompu asebenza ngokuqhubekayo ngesikhathi sokukhishwanga kwamanzi, adinga imithombo yamandla ethembekile kanye nok维护 okujwayelekile ukuze kuqinisekiswe ukusebenza phakathi kwezinsuku ezinde zokwakha izisekelo. Izicelo ezivamile zamabhompu aphezulu wokuhlinzeka zifaka imiklamo yokumba ezijulile, ukwakhiwa kwezikhwama, ukufakwa kwe-diaphragm wall, kanye nezinhlelo zokuphumpa ama-pile anedwala elikhulu lapho kulawulwa amanzi angaphansi kubalulekile ukuze kuqinisekiswe ukuphepha kwabasebenzi nokuba nokwakhiwa okuqine. Lezi zinhlelo zisetshenziswa njalo emikhakheni ehlanganisa ukwakhiwa kwezimoto, imigwaqo ye-subway, izisekelo ezakhelwe olwandle, kanye nokubekwa kabusha kwezinto lapho kunciphiswa khona umfutho we-hydrostatic ezakhiweni zesikhashana noma eziphakeme kuyinto ebalulekile. Amabhompu aphezulu wokuhlinzeka kufanele akwazi ukubhekana nezinto eziphukile nezinto eziphakeme ezijwayelekile emisebenzini yokukhishwa kwamanzi, kudinga izinsiza zokwakha eziqinile, ukuhlanganiswa okuhle kokuhlunga, kanye nezinhlelo zokuphuma ezivalwe. Ukukhetha, ukufakwa, nokusebenza kahle kwamabhompu aphezulu wokuhlinzeka kuthinta ngqo izinsuku zomsebenzi, ukusebenza kahle kwezindleko, kanye nempumelelo jikelele yecebo lokulawula amanzi angaphansi ezimweni ezinzima ze-geotechnical ezingadinga ukwehla okuqhubekayo kwamathafa amanzi nezinga le-piezometric emaphethelweni omgwaqo wokwakhiwa kwezisekelo.
