Yimiphi imisebenzi yezinqwaba zensimbi ezakhiwe ngamakhaza kumaphrojekthi okulondolozwa kwamanzi kanye nokukhipha amanzi?

Izinqwaba zensimbi ezakhiwe ngokubandayo sezibe yinto ebalulekile kumaphrojekthi okulondolozwa kwamanzi kanye nokukhipha amanzi ngenxa yokuguquguquka nokuqina kwazo. Lapho uthenga lezi zinto ezibalulekile, kubalulekile ukuthola umhlinzeki wezinqwaba zeshidi onokwethenjelwa onikeza intengo encintisanayo yezinqwaba zeshidi kanye nezinhlobo ezahlukene zezinqwaba zeshidi zensimbi, kufaka phakathi inqwaba yeshidi eligoqiwe elibandayo.
Emisebenzini yokongiwa kwamanzi kanye nokukhipha amanzi, indimaizinqwaba zeshidi lensimbi elenziwe ngamakhazaayibalulekile. Lezi zinqwaba zamaphepha zisetshenziselwa izinjongo ezahlukahlukene njengokwakha izindonga zokuvikela, ama-cofferdams kanye nama-bulkhead. Zisetshenziselwa futhi ukwakha izithiyo zezikhukhula kanye nezakhiwo zokulawula ukuguguleka komhlabathi. Ukuguquguquka kwezinqwaba zamaphepha ensimbi ezakhiwe ngamakhaza kuzenza zilungele amaphrojekthi adinga ukuphathwa kwamanzi okusebenzayo kanye nokuvikelwa ezintweni zemvelo.
Uma ukhetha abahlinzeki bezinqwaba zamashidi, kubalulekile ukucabangela ikhwalithi nokuthembeka kwemikhiqizo abayinikezayo. Izinqwaba zamashidi ensimbi ezibandayo kufanele zihambisane nezindinganiso kanye nemininingwane yemboni ukuqinisekisa ukusebenza kwazo kumaphrojekthi okulondolozwa kwamanzi kanye nokukhipha amanzi. Ngaphezu kwalokho, abahlinzeki kufanele banikeze amanani okuncintisana okuhlanganisa amashidi afanelana nesabelomali sephrojekthi ngaphandle kokubeka engcupheni ikhwalithi.
Izinqwaba zeshidi ezigoqiwe ezibandayosezibe yisinqumo esithandwayo samaphrojekthi okulondolozwa kwamanzi kanye nokukhipha amanzi ngenxa yamandla awo aphezulu kanye nokuqina kwawo. Inokumelana okuhle kakhulu nokugqwala futhi ingamelana nezimo zemvelo ezinzima, okwenza kube yisisombululo esihlala isikhathi eside sengqalasizinda yokuphathwa kwamanzi.

Kunezinhlobo eziningi zezinqwaba zensimbi, ngayinye inezici zayo ezihlukile kanye nezinzuzo zayo. Ukuqonda izinhlobo ezahlukene zezinqwaba zensimbi kungasiza ekukhetheni inketho efanele kakhulu yezidingo ezithile zephrojekthi. Kungakhathaliseki ukuthi ziyinqwaba yeshidi enobunjwa buka-U, obunjwa ngu-Z noma obuqondile, ukuthola zonke izinhlobo zezinqwaba zensimbi kubahlinzeki abathembekile kubalulekile ekuqinisekiseni impumelelo yephrojekthi yakho yamanzi kanye nokuthuthwa kwamanzi.
Ngamafuphi, ukusebenza kwezinqwaba zensimbi ezakhiwe ngamakhaza kumaphrojekthi okulondolozwa kwamanzi kanye nokukhipha amanzi kubalulekile ekudaleni ingqalasizinda eqhubekayo neqinile. Ngokubambisana nenkampani ethembekileumhlinzeki wenqwaba yeshidiNjengoba benikeza amanani ancintisanayo enqwaba yamaphepha kanye nokukhethwa okubanzi kwezinhlobo zenqwaba yamaphepha, abaphathi bephrojekthi bangaqinisekisa ukuqaliswa ngempumelelo kwesisombululo sokuphathwa kwamanzi esihlala isikhathi eside.
