Emisebenzini yokwakha, ukuqinisekisa ubuqotho nokuphila isikhathi eside kwesakhiwo kubalulekile. Isici esibalulekile kule nqubo ukusetshenziswa kwe-high-density polyethylene (HDPE)izindawo zokumisa amanzi. Lezi zakhi ezincane kodwa ezinamandla zidlala indima ebalulekile ekuvimbeleni ukuphuma kwamanzi nokuqinisekisa ukuqina okuphelele kwesakhiwo sikakhonkolo.
Izitobha zamanzi ze-HDPE ziklanyelwe ukuhlinzeka ngophawu olungangeni manzi kumajoyini wokwakha, amalunga okunweba, nezinye izindawo ezisengozini lapho ukungena kwamanzi kungase kuphazamise ubuqotho besakhiwo. Ngokuvamile zisetshenziswa emisebenzini eyahlukahlukene yokwakha edinga ukuvinjelwa kwamanzi, njengezindlu ezingaphansi, izindawo zokuhlanza amanzi, imigudu namadamu.
Enye yezinzuzo eziyinhloko zesitobhi samanzi se-HDPE ukumelana kwayo okuphakeme namakhemikhali nokonakaliswa kwemvelo. Lokhu kuzenza zilungele ukusetshenziswa ezimeni ezinzima nezifunayo lapho ukuchayeka emanzini, kumakhemikhali nezinye izinto ezigqwalayo kuwusongo oluqhubekayo. Ukuqina kwabo kuqinisekisa ukusebenza kwesikhathi eside, kunciphisa isidingo sokugcinwa njalo nokulungiswa.
Ngaphezu kokumelana nokuwohloka, izitobha zamanzi ze-HDPE ziguquguquka kakhulu, ezivumela ukuthi zikwazi ukwamukela ukunyakaza nokuhlala ngaphakathi kwezakhiwo ezikhonkolo. Lokhu kuvumelana nezimo kubalulekile ekuvimbeleni ukuqhekeka nokuvuza ngoba kuvumela indawo yokugcina amanzi ukuthi ivumelane nezimo ezishintshayo ngaphandle kokuphazamisa ukusebenza kwayo.
Ukwengeza, ukufaka isitobha samanzi se-HDPE kulula futhi kuyabiza. Azisindi futhi kulula ukuziphatha, okwenza kube lula ukuthi izisebenzi zokwakha ziwafake, zonga isikhathi nezindleko zabasebenzi. Lokhu lula kokufaka kunomthelela ekusebenzeni kahle okuphelele kwenqubo yokwakha.
Mayelana nokusimama, izindawo zokumisa amanzi ze-HDPE ziyinketho evumelana nemvelo. Impilo yabo ende kanye nokumelana nokucekelwa phansi kusho ukuthi basiza ukwelula impilo yesakhiwo abafakwe kuso, benciphisa isidingo sokushintshwa njalo kanye nokunciphisa imfucuza.
Kumele kuqashelwe ukuthi ukukhethwa nokufakwa kwe-HDPE waterstops kufanele kwenziwe ochwepheshe abanolwazi ukuze kuqinisekiswe ukusebenza kwabo okujwayelekile. Amasu okufaka afanele, okuhlanganisa ukushisela kanye nobuqotho be-seam, abalulekile ekwandiseni ukusebenza kahle kwe-watertop.
Kafushane,I-HDPE iyama amanziziyingxenye ebalulekile yamaphrojekthi wokwakha futhi zidlala indima ebalulekile ekuvimbeleni ukungena kwamanzi kanye nokuqinisekisa ukuqina kwezakhiwo zikakhonkolo. Ukumelana kwabo nokucekelwa phansi, ukuguquguquka, ukufakwa kalula nokusimama kubenza babe yimpahla ebalulekile embonini yezokwakha. Ngokuhlanganisa izindawo zokumisa amanzi ze-HDPE ezinhlelweni zokwakha, abakhi bangandisa isikhathi eside nokusebenza kwezakhiwo zabo, ekugcineni bathole ingqalasizinda ephephile, nethembekile.
