Iinqwaba zesinyithi zentsimbi ezimile okwe-Z, izinto zokugcina ezisebenza kakhulu nezisetyenziswa kakhulu, zibizwa ngokuba zifana nonobumba u-“Z” kwicandelo lazo elinqamlezileyo. Iinqwaba zesinyithi zohlobo lwe-U (Larsen) Ezi ntlobo zimbini xa zidibene zenza umqolo wobunjineli beenqwaba zesinyithi zanamhlanje ezineempawu ezahluke kakhulu ekusebenzeni kwesakhiwo kunye nendawo yokusetyenziswa.
Iingenelo:
Umlinganiselo ophezulu we-modulus-to-weight ratio ukuze kusebenze kakuhle
Ukuqina okwandileyo kunciphisa ukuphambuka
Uyilo olubanzi luvumela ukufakwa lula
Ukumelana nokugqwala okuphezulu, kunye nobukhulu obungaphezulu kwiindawo ezibalulekileyo
I-Hot Rolled Au Pu 6m-18m U-Shaped Steel Sheet Pile sisisombululo sentsimbi esomeleleyo nesiqinileyo esenzelwe ukugcina iindonga, izakhiwo zasemanzini, kunye neeprojekthi zokugcina umhlaba.
Inqwaba yeshiti yentsimbiineendlela ezahlukeneyo zokusetyenziswa kwaye ingasetyenziswa kwiinkqubo ezahlukeneyo zokubambelela. Iyakwazi ukuguquguquka kakuhle emhlabeni nasemanzini, kwaye ingasetyenziswa kwiiprojekthi zokwakha, kwiindawo zokubeka iinqanawa nakwiindawo zokubeka iinqanawa apho zombini zinokubakho, kwaye ingasetyenziselwa ukuxhasa imingxuma yesiseko enzulu kunye neetanki zokugcina isinyithi.
Ukusebenza kakuhle kweiinqwaba zeshiti zentsimbiIbonakala kulwakhiwo olutsha lweemveliso ezininzi ezintsha, ezinje ngezakhiwo ezikhethekileyo zokuwelda; Umqhubi wenqwaba yokungcangcazela ye-hydraulic yokwenza ipleyiti yesinyithi; Umxube we-seal combination sluice kunye nonyango lwepeyinti yefektri. Izinto ezininzi ziqinisekisa ukuba inqwaba yeshiti ihlala yenye yezona zinto ziluncedo kakhulu zokwenza imveliso: ayincedi nje kuphela ekuphuculeni umgangatho wentsimbi, kodwa ikwanceda uphando kunye nophuhliso lwemarike yenqwaba yeshiti; Inceda ukuphucula uyilo lweempawu zemveliso kunye nokuhlangabezana ngcono neemfuno zabasebenzisi.
Iingqumba zesinyithi ziindawo ezinde zesakhiwo ezineekhonkco ezidibeneyo, ezisetyenziswa rhoqo njengeendonga zokugcina amanzi kwizakhiwo zasemanzini, ii-cofferdams, kunye nezinye izinto zokugcina umhlaba okanye amanzi. Zenziwe ngentsimbi ukuze ziqine kwaye zihlale ixesha elide, uyilo lwazo lokuqhagamshela luvumela iindonga eziqhubekayo, zibonelela ngenkxaso efanelekileyo yokwemba kunye neeprojekthi zesakhiwo.
Iinqwaba zesinyithi ezenziwe ngombala we-U ezenziwe ngentsimbi ye-S235, S275, okanye ye-S355, ubude obuyi-6–18 m, zilungele ukugcinwa kweendonga, ii-cofferdams, kunye neziseko.
EziIinqwaba zePhepha zeNsimbi ezimile okwe-UZenziwe ngokubandayo ngokusekelwe kumgangatho we-GB kwaye zingafumaneka kwiiklasi ezinamandla aphezulu ze-Q235b, Q345b, Q390 kunye ne-Q420. Zisetyenziselwa ukugcina iindonga, iziseko, ii-cofferdams kunye neminye imisebenzi emininzi yobunjineli bokwakha kwaye zibonelelwa ngobude ukusuka kwi-6m ukuya kwi-18m. Uyilo lwe-Cold Formed U Pile lubonelela ngobukhulu obuhambelanayo kunye nendlela yokudibanisa, ukuqina okuphezulu kumhlaba nakwimeko yamanzi.
Uhlobo lwe-U 2ukunqwabelanisa ishidi lentsimbisisixhobo esisetyenziswa kakhulu ukugcina umhlaba kunye nokuxhasa ukumba. Senziwe ngentsimbi enamandla kwaye sinendawo enqamlezileyo efana no-U, sibonelela ngozinzo kunye nokuqina kwesakhiwo. Iinqwaba zamaphepha e-U Type 2 zenzelwe ukunxulumana, zidala udonga oluqhubekayo lwezicelo ezahlukeneyo zokwakha ezifana nezakhiwo zasemanzini, ii-cofferdams, kunye neendonga zokugcina. Ukuguquguquka kunye namandla okuhlanganisa amaphepha esinyithi e-U Type 2 kwenza ukuba ibe lukhetho oludumileyo kwiiprojekthi zobunjineli bokwakha ezifuna izisombululo zokugcina umhlaba ezisebenzayo nezithembekileyo.
Inqwaba yeshiti yentsimbi ethayishwe ngo-Zlicandelo lesakhiwo elisebenza kakuhle elifumana usetyenziso olubanzi kubunjineli bokwakha kunye nolwakhiwo lwezakhiwo. Imilo yaloInqwaba yeshiti yentsimbi emile okwe-Zkwaye i-interlock yayo inika ukumelana okubalaseleyo komthwalo osecaleni, uzinzo kunye nokuqina, yiyo loo nto zisetyenziselwa ukuqeqesha ukwakhiwa kweendonga, udonga lwamanzi, amazibuko, kunye nokumba nzulu okungaphaya komlambo.
Inqwaba yentsimbi egoqwe ngombala we-U yenzelwe iimfuno ezinzima zesakhiwo kubunjineli bokwakha kunye nokusetyenziswa kwezakhiwo. Inamandla aphezulu kwaye inokufumaneka kwiindidi ze-SY295, SY390 kunye ne-SY490. Ezi nqwaba zenziwe ngokwemigangatho ye-ASTM A328 kunye ne-JIS A5528 ukuqinisekisa ukuba inqwaba ikumgangatho ophezulu.
Iingqumba zesinyithi ze-U ziinxalenye ezidityanisiweyo okanye ezicinezelweyo ezenza udonga olufanayo, olusetyenziswa rhoqo ukugcina umhlaba okanye amanzi. Amandla engqumba yephepha axhomekeke kwimilo yeprofayili kunye neempawu zomhlaba kwaye isebenza ekudluliseleni uxinzelelo olukwicala eliphezulu lodonga kumhlaba okufutshane.
