Ama-Wellpoints e-Self-Jetting

Iziphakamisi ezizimele zokugaya amanzi zimelela indlela ekhethekile yokuphuma kwamanzi esebenziswe kwi-ingxenye yokwakha izakhiwo ezinzulu kanye nezinsiza ze-geotechnical ukulawula nokuwa kwezinga lamanzi phansi emathafeni okumba nokwakha. Le ndlela isebenzisa amajethi amanzi agxile aphezulu, avame ukusebenza ngamaphesenti aphakathi kuka-300 kuya ku-600 bar, ukuze ngempumelelo akwazi ukungena futhi afake amapayipi amancane wokugaya amanzi ngqo emithonjeni egcwele amanzi ngaphandle kokufuna izinsiza ezinzima zokubhola noma ukulungiswa okubanzi. Le ndlela yokuhlunga ithuthukisa ukufakwa kwezimali zokugaya amanzi ezindaweni eziqinile nezakhiwo eziphakathi nendawo, yenze le nqubo ikhethekile kalula kubaklami abasebenza ngezinhlelo ezibucayi noma ezindaweni ezivamile zokuhlala lapho izinsiza zokubhola ezijwayelekile zingasebenzi noma zikhawulelwe. Uhlelo lwezikhungo zokugaya amanzi lwezizimele luqukethe izingxenye ezihlanganyelwe kufaka phakathi i-jetting pump unit, izikhwama zokwabelana, ama-risers ama- wellpoint ngamaphepha aphukile, kanye ne-manifold yesikhungo exhunywe kumpompo wokukhipha amanzi. Le nqubo ihilela ukufaka i-nozzle ye-jetting ezingeni lomhlaba futhi iphoqele amanzi agxile ngokweqile phansi ngepayipi lewellpoint, okwenza kube lula ukujula phakathi komhlaba ozungezile futhi kuvumele ipayipi ukuba lehlise ngokwesisindo sako kanye nengcindezi ye-hydrostatic. Le ndlela yokufaka ibonakala ikhululekile kakhulu emathafeni e-granular anjengezihlahla kanye nezithako lapho izimo zomhlaba zikhathazeka ngokuhlanza amanzi kanye nokungena amanzi ngezinga eliphezulu. Kulabo abafaka izinsiza zezimali ezinzulu ezidinga ukulawulwa okukhulu kwamanzi, iziphakamiso zokugaya amanzi ezizimele zinikeza ubuhle obukhulu uma kuqhathaniswa nezinhlelo ezijwayelekile, njengoba ama-wellpoints amaningi angafakwa ezindaweni ezizungezile zamaphetho, izigqoko ze-pile, noma izindawo zokumba zemithi ukuze kuqinisekiswe ukungena kwamanzi okuphelele ezindaweni ezinkulu zokwakha. Izicelo ezindaweni zokwakha izisekelo ezinzulu zifaka ukugaya amanzi ezindaweni ezinkulu ezinama-diameter, izikhalazo ze-pile sheet, ukufaka izindonga ze-diaphragm, nezindawo zokumba eziphansi lapho ukugcina izimo zokusebenza ezomile kubalulekile ukuze kuqinisekiswe ukusebenza kahle kokuhlinzeka ngama-pile kanye nezinga le-concrete. Le ndlela ihlanganisa kahle ne-systems zokwakha ze-vibro-displacement kanye nama-hammers we-impact pile, ivumele abaklami ukukhipha amanzi angene ngenkathi behamba or befaka ama-pile. Le ndlela yokugaya amanzi iphinde ihlangabezane nezimo zomhlaba ezinzima okubandakanya ukwakheka kwezindonga, izindawo ezinemithombo evamile, kanye nezindawo lapho ukubhola okukhukhumelelayo kuzohlobo lwe-pulp kungaphazamisa ukugcinwa komhlaba. Ikhono lokukhipha amanzi elitholakala ngezinhlaka ezizimele eziklanywe kahle lingavela phakathi kuka-500 kuya kwi ezingu-izinkulungwane eziyizinkulungwane ze-cubic meters nsuku zonke, kuye nge-permeability yomhlaba, izidingo zokuhlanza, nokuhamba kwama-wellpoints active emsebenzini. Izinhlelo zokugaya amanzi ezizimele zimelela isixazululo esihlanganyele esiphumelele, silula, nesimeme sokukhipha amanzi kumakhasimende e-geotechnical kanye noshintsho lwezikhwama. Le teknoloji inciphisa ukuphazamiseka komhlaba uma kuqhathaniswa nokubhola kwezimali ezinkulu, inciphisa isikhathi sokufaka kahle kakhulu, futhi ivumela ukuphathwa okuhlukahlukanisayo ezindaweni zokwakha ezahlukene. Ukuklanywa kahle nokuhlelwa kwezinhlelo zokugaya amanzi kudinga ukuqonda kwezimo zokwakha komhlaba, amaphethini okuhamba kwamanzi, kanye nezindlela zokuhlanza ezithile zephrojekthi yezakhiwo ngazinye. Ukuhlanganiswa kokufaka ngokushesha, ukujolisa ezimweni zomhlaba ezinzima, kanye nokwethembeka okuqinisekisiwe kwenza iziphakamiso zokugaya amanzi ezizimele kube yinxenye ebalulekile yezinhlelo zokwakha ezinzulu zendawo nezokukhipha amanzi ze-geotechnical emikhakheni yokwakha, yezimboni, kanye nezinsiza.
