Kukuziphi izimo lapho kufanele kusetshenziswe khona izinqwaba zensimbi zaseLassen?

Igama lesiNgisi lithiInqwaba Yeshidi Lensimbi Lassennoma iLassen SteelUkufakwa KwamashidiAbantu abaningi eShayina babiza insimbi yesiteshi ngokuthi izinqwaba zeshidi lensimbi; ukuze kuhlukaniswe, ihunyushwa ngokuthi izinqwaba zeshidi lensimbi laseLassen.

Ukusetshenziswa: Izinqwaba zensimbi zaseLassen zinezinhlobo eziningi zezicelo. Ezikhiweni ezihlala njalo, zingasetshenziswa ezindaweni zokubeka imikhumbi, izindawo zokukhipha imithwalo, izindawo zokubeka imithwalo, izindonga zokugcina imithwalo, izindonga zokugcina umhlaba, izindawo zokuvimba amanzi, izindawo zokubeka imithwalo, izindawo zokubeka imithwalo eyomile, kanye namasango. Ezikhiweni zesikhashana, zisebenza ekuvaleni izintaba, ekunwetshweni kwebhange lesikhashana, ekuphazamisekeni kokugeleza kwamanzi, emabhulohweni, kanye nasekumbiweni kwemisele yesikhashana yokubeka amapayipi amakhulu ukuvimbela inhlabathi, amanzi, kanye nesihlabathi.

Ububanzi Bokusetshenziswa: Njengezinto zokwakha ezintsha, izinqwaba zensimbi zaseLassen zisebenza njengezindonga zokugcina umhlaba, amanzi, nesihlabathi ngesikhathi sokwakhiwa kwebhuloho laseCofferdam, ukufakwa kwamapayipi amakhulu, kanye nokumbiwa kwemisele yesikhashana. Zisebenza futhi njengezindonga ezivikelayo ezindaweni zokubeka impahla nasezindaweni zokukhipha impahla, kanye nezindonga zokulondoloza umhlaba kanye nama-levees.

Izinqwaba zeshidi lensimbi zihlukaniswe ngokuyinhloko ngezimo ezintathu ngokusekelwe esigabeni kanye nenhloso: Ezimise okwe-U, Ezimise okwe-Z, kanye Nezimise okwe-W. Ngaphezu kwalokho, zingahlukaniswa zibe izinqwaba zeshidi lensimbi ezisebenza kalula kanye nezijwayelekile ezibandayo ngokusekelwe ekujikeni kodonga. Izinqwaba zeshidi lensimbi ezisebenza kalula zinobukhulu bodonga obungu-4 kuya ku-7 mm, kanti ezijwayelekile zisukela ku-8 kuya ku-12 mm. Iningi lase-Asia, kufaka phakathi iShayina, lisebenzisa kakhulu izinqwaba zeshidi lensimbi laseLarsen ezixhumene nohlobo lwe-U.

Imikhiqizo ingahlukaniswa ngokwezinqubo zokukhiqiza ibe yizinqwaba zensimbi ezakhiwe ngokubandayo kanye nezigoqwe ngokushisa. Ekwakhiweni, izinqwaba zensimbi ezakhiwe ngokubandayo zinikeza isilinganiso esihle sokusebenza kwezindleko, futhi zombili izinhlobo zingashintshwana ngezinhlelo ezingokoqobo.

Izinzuzo ezibalulekile zifaka:
1. Ukwakhiwa okulula, isikhathi sephrojekthi esincishisiwe, ukuqina okuhle kakhulu, isikhathi sokuphila esingaphezu kweminyaka engama-50.
2. Izindleko zokwakha eziphansi, ukushintshaniswa okuhle, kanye nethuba lokusetshenziswa kabusha.
3. Ukuncipha kwezidingo zendawo.
4. Izinzuzo ezinkulu zemvelo, njengoba zinciphisa kakhulu ukukhishwa kwenhlabathi nokusetshenziswa kokhonkolo, zilondoloza ngempumelelo izinsiza zomhlaba.

Izinqwaba zethu zensimbi zenziwe ngensimbi enamandla amakhulu, zinikeza amandla aqine kakhulu okucindezela nokugoba. Kungakhathaliseki ukuthi ze-cofferdams, ukwesekwa kokumba, noma ukuvikelwa kogu lomfula, zimelana ngempumelelo nezingcindezi zangaphandle futhi ziqinisekisa ukuzinza kwesakhiwo. Umklamo oyingqayizivele wokuxhumanisa uvumela ukuxhumana okuqinile ngesikhathi sokufakwa, kwakha udonga oluqhubekayo futhi kuthuthukisa kakhulu ukuvalwa okuphelele nokusebenza okungangeni manzi. Ngaphezu kwalokho, izinqwaba zethu zensimbi zingasetshenziswa kabusha, zehlisa izindleko zephrojekthi futhi zihambisana nezimiso ezinobungani nemvelo. Ziyisinqumo esifanele samaphrojekthi okwakha amadolobha kanye nengqalasizinda. Ngethimba lochwepheshe kanye nokulawulwa kwekhwalithi okuqinile, sikunikeza imikhiqizo yenqwaba yensimbi esezingeni eliphezulu kanye nensizakalo ephelele yangemva kokuthengisa. Khetha izinqwaba zethu zensimbi ukuze ubeke isisekelo esiqinile sephrojekthi yakho!
