Iingqumba zesinyithi zentsimbi, njengezinto ezixhasa ulwakhiwo ezidibanisa amandla kunye nokuguquguquka, zidlala indima engenakutshintshwa kwiiprojekthi zokugcina amanzi, ukwakhiwa kokumba isiseko esinzulu, ukwakhiwa kwezibuko, kunye nezinye iindawo. Iintlobo zazo ezahlukeneyo, iinkqubo zemveliso ezintsonkothileyo, kunye nokusetyenziswa okubanzi kwihlabathi liphela kuzenza zibe zizinto ezibalulekileyo zokuqinisekisa ukhuseleko kunye nokuphucula ukusebenza kakuhle kolwakhiwo. Eli nqaku liza kubonelela ngohlalutyo oluneenkcukacha lweentlobo eziphambili zeengqumba zesinyithi zesinyithi, umahluko wazo, iindlela zemveliso eziqhelekileyo, kunye nobukhulu obuqhelekileyo kunye neenkcukacha, zibonelela ngereferensi epheleleyo kwiingcali zokwakha kunye nabathengi.
Iinqwaba zeshiti zentsimbizihlulwe ngokwemilo enqamlezileyo. Iinqwaba zesinyithi zohlobo lwe-Z kunye ne-U zezona zikhethwa kakhulu kubunjineli ngenxa yoluhlu olubanzi lwezicelo kunye neenzuzo zokusebenza ezibalaseleyo. Nangona kunjalo, kukho umahluko omkhulu phakathi kwezi ntlobo zimbini ngokwesakhiwo, ukusebenza, kunye neemeko zokusetyenziswa:
Iinqwaba zesinyithi zentsimbi ezimile okwe-U: Zinesakhiwo esifana nomjelo ovulekileyo kunye nemiphetho etshixayo ukuze ilingane kakuhle, nto leyo evumela ukuba zilungelelanise ngokuguquguqukayo neemfuno ezinkulu zokuguquguquka kwiiprojekthi zobunjineli. Iipropati zazo ezibalaseleyo zokuguquguquka zenza ukuba zisetyenziswe kakhulu kwiiprojekthi ze-hydraulic ezikumgangatho ophezulu wamanzi (ezifana nolawulo lomlambo kunye nokuqinisa i-reservoir embankment) kunye nenkxaso yesiseko esinzulu (ezifana nokwakhiwa komhlaba phantsi komhlaba kwezakhiwo eziphakamileyo). Okwangoku zezona nqwaba zesinyithi ezisetyenziswa kakhulu kwimarike.
Iinqwaba zesinyithi zentsimbi ezimile okwe-Z: Zinecandelo elivaliweyo, eligobileyo elineepleyiti zentsimbi ezijiyileyo kumacala omabini, nto leyo ebangela ukuba kubekho i-modulus ephezulu kunye nokuqina okuphezulu kwe-flexural. Oku kuvumela ulawulo oluchanekileyo lokuguqulwa kobunjineli kwaye kufanelekile kwiiprojekthi eziphezulu ezineemfuno zolawulo lokuguqulwa okungqongqo (ezifana nemigodi yesiseko sefektri echanekileyo kunye nokwakhiwa kwesiseko sebhulorho enkulu). Nangona kunjalo, ngenxa yobunzima bobuchwephesha bokuqengqeleka okungalinganiyo, ziinkampani ezine kuphela kwihlabathi liphela ezinomthamo wemveliso, nto leyo eyenza olu hlobo lwenqwaba yamaphepha lube nzima kakhulu.
Inkqubo yokuvelisa iinqwaba zeeshiti zentsimbi ichaphazela ngokuthe ngqo ukusebenza kwazo kunye nokusetyenziswa kwazo okufanelekileyo. Okwangoku, ukuqengqeleka okushushu kunye nokugoba okubandayo zezona ndlela zimbini ziphambili ezisetyenziswayo kushishino, nganye inengqwalasela yayo eyahlukileyo kwiinkqubo zemveliso, iimpawu zemveliso, kunye nokubekwa kwindawo yesicelo:
Iinqwaba zesinyithi zentsimbi eziqengqelekayo ezishushuzenziwe ngeebhilethi zentsimbi, zifudunyezwe ukuya kumaqondo obushushu aphezulu, zize zisongwe zibe yimo kusetyenziswa izixhobo ezikhethekileyo. Imveliso egqityiweyo inika ukuchaneka okuphezulu kokutshixa kunye namandla aphezulu ngokubanzi, nto leyo eyenza ukuba ibe yimveliso ehamba phambili kwiiprojekthi zobunjineli. I-Royal Steel Group isebenzisa inkqubo yokuqengqeleka elandelelanayo ukubonelela ngeepila ezimile okwe-U ezinobubanzi obuyi-400-900mm kunye neepila ezimile okwe-Z ezinobubanzi obuyi-500-850mm. Iimveliso zabo zisebenze kakuhle kakhulu kwiShenzhen-Zhongshan Tunnel, nto leyo ebazuzela udumo "lokuzinzisa iipila" kumnini weprojekthi, nto leyo ebonisa ngokupheleleyo ukuthembeka kwenkqubo yokuqengqeleka eshushu.
Iinqwaba zesinyithi ezenziwe ngentsimbi ebandayoZenziwe ngee-rolls kubushushu begumbi, nto leyo esusa isidingo sonyango olushushu. Oku kubangela ukuba umphezulu ube mhle kwaye ungabi nangxaki yokugqwala ngama-30%-50% kunee-hot-rolled piles. Zifanelekile ukusetyenziswa kwiindawo ezifumileyo, ezikunxweme, nezinokugqwala (umz., ukwakhiwa kwesiseko somngxuma). Nangona kunjalo, ngenxa yemida yenkqubo yokwenza ubushushu begumbi, ukuqina kwazo okunqamlezileyo kubuthathaka. Zisetyenziswa kakhulu njengezinto ezongezelelweyo, kunye nee-hot-rolled piles ukuphucula iindleko zeprojekthi kunye nokusebenza kwayo.
Iindidi ezahlukeneyo zeenqwaba zesinyithi zinemilinganiselo ecacileyo yobukhulu. Ukuthengwa kweprojekthi kufuneka kuqwalasele iimfuno ezithile (ezifana nobunzulu bokumba kunye nobunzima bomthwalo) ukuze kukhethwe iinkcukacha ezifanelekileyo. Ezi zilandelayo zimilinganiselo eziqhelekileyo kwiindidi ezimbini eziphambili zeenqwaba zesinyithi:
Iinqwaba zentsimbi ezimile okwe-U: Inkcazo eqhelekileyo idla ngokuba yi-SP-U 400×170×15.5, ububanzi buqala kwi-400-600mm, ubukhulu buqala kwi-8-16mm, kunye nobude be-6m, 9m, kunye ne-12m. Kwiimfuno ezikhethekileyo ezifana nokumba okukhulu, okunzulu, ezinye iinqwaba ezimile okwe-U ezigoqwe ngobushushu zinokwenziwa ngokwezifiso ukuya kuthi ga kwi-33m ukuze kuhlangatyezwane neemfuno zenkxaso enzulu.
Iinqwaba zesinyithi ezimile okwe-Z: Ngenxa yemida yenkqubo yemveliso, ubukhulu bufana kakhulu, ubude obuphakathi buqala kwi-800-2000mm kwaye ubukhulu buqala kwi-8-30mm. Ubude obuqhelekileyo buhlala buphakathi kwe-15-20m. Iinkcukacha ezinde zifuna ukubonisana kwangaphambili nomenzi ukuqinisekisa ukuba inkqubo iyasebenziseka.
Ukususela kumazibuko akuMzantsi-mpuma weAsia ukuya kwiindawo zokugcina amanzi eMntla Melika, iinqwaba zesinyithi, kunye nokuguquguquka kwazo, zisetyenziswe kwiiprojekthi ezahlukeneyo kwihlabathi liphela. Ezi zilandelayo ziingxelo ezintathu eziqhelekileyo ezivela kubathengi bethu, ezibonisa ixabiso lazo elisebenzayo:
Iprojekthi Yokwandiswa Kwezibuko lasePhilippines: Ngexesha lokwandiswa kwezibuko ePhilippines, kwakubonakala ngathi kukho umngcipheko wokwanda kwezivuthuvuthu okubangelwa zizivuthuvuthu ezihlala zisenzeka. Isebe lethu lobuchwephesha licebise ukuba kusetyenziswe iinqwaba zesinyithi ezijijekileyo ezihot-rolled ezimile okwe-U kwi-cofferdam. Indlela yabo yokutshixa ngokuqinileyo yamelana ngempumelelo nempembelelo yokwanda kwezivuthuvuthu, iqinisekisa ukhuseleko kunye nenkqubela phambili yokwakhiwa kwezibuko.
Iprojekthi yokulungisa i-hub yolondolozo lwamanzi yaseKhanada: Ngenxa yobusika obubandayo kwindawo ye-hub, umhlaba unokuba notshintsho olubangelwa yimijikelo yokuqandisa nokunyibilika, nto leyo efuna uzinzo oluphezulu kakhulu. Isebe lethu lobuchwephesha licebise ukusetyenziswa kweenqwaba zesinyithi ezigoqwe ngobushushu ezimile okwe-Z ukuze ziqiniswe. Amandla azo aphezulu anokumelana notshintsho olubangelwa luxinzelelo lomhlaba, ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwe-hub yolondolozo lwamanzi.
Iprojekthi yokwakha isakhiwo sentsimbi eGuyana: Ngexesha lokwakhiwa komngxuma wesiseko, iprojekthi yayifuna ulawulo olungqongqo lokuguqulwa komngxuma ukuqinisekisa ukhuseleko lwesakhiwo esiphambili. Umenzi wekontraka watshintshela kwiinqwaba zethu zesinyithi ezenziwe ngokubanda ukuze aqinise umngxuma wesiseko, edibanisa ukumelana nokugqwala kwazo kunye nokuzivumelanisa nokusingqongileyo okufumileyo kwendawo ukuze agqibezele ngempumelelo iprojekthi.
