Insimbi yesiteshi se-CIzinsika zivame ukwenziwa ngensimbi yekhabhoni esezingeni eliphezulu enamandla aphezulu kanye nomthamo wokuthwala umthwalo. Isakhiwo sensika eyodwa silula ngokuklama futhi kulula ukuyifaka ezinhlotsheni ezahlukahlukene zokwakha kanye nezinhlelo zokusekela zemishini. Isimo saso sesigaba esiphambeneyo senza insika ibe nokuqina okuhle kokubili kobude obude kanye nobubanzi obuphambeneyo, ifanele ukuthwala imithwalo emikhulu. Ngaphezu kwalokho, insimbi yesiteshi se-C inokumelana okuhle nokugqwala futhi ingagcina impilo yenkonzo ende ezindaweni ezinzima, okwenza ibe yindawo ekahle yokusetshenziswa ezindaweni ezifana nezitshalo zezimboni kanye nezindawo zokugcina impahla.
Izinqwaba zensimbi ezimise okwe-Z, into yokugcina ephumelela kakhulu futhi esetshenziswa kabanzi, iqanjwe ngokufana kwayo nohlamvu "Z" esigabeni sayo esiphambene. Izinqwaba zensimbi zohlobo lwe-U (Larsen) Lezi zinhlobo ezimbili ndawonye zakha umgogodla wobunjiniyela bezintambo zensimbi zanamuhla ezinezici ezihluke kakhulu ekusebenzeni kwesakhiwo kanye nensimu yokusetshenziswa.
Izinzuzo:
Isilinganiso sesisindo se-modulus sesigaba esiphezulu ukuze kusebenze kahle
Ukuqina okwandisiwe kunciphisa ukuphambuka
Umklamo obanzi uvumela ukufakwa okulula
Ukumelana nokugqwala okuphezulu, kanye nobukhulu obengeziwe ezindaweni ezibucayi
I-Hot Rolled Au Pu 6m-18m U-Shaped Steel Sheet Pile iyisisombululo sensimbi esiqinile nesinamandla amakhulu esenzelwe ukuvikela izindonga, izakhiwo zasemanzini, kanye namaphrojekthi okugcina umhlaba.
Inqwaba yeshidi lensimbiinezinhlobo eziningi zezicelo futhi ingasetshenziswa ezinhlelweni ezahlukene zokubambelela. Iyakwazi ukuzivumelanisa nezimo kokubili enhlabathini nasemanzini, futhi ingasetshenziswa kumaphrojekthi okwakha, ezindaweni zokubeka imikhumbi kanye nasezindaweni zokubeka imikhumbi lapho kokubili kungase kube khona, futhi ingasetshenziswa futhi ukusekela imigodi ejulile yesisekelo kanye namathangi okugcina insimbi.
Ukusebenza kahle kweizinqwaba zeshidi lensimbikubonakala ekwakhiweni okusha kwemikhiqizo eminingi emisha, njengezakhiwo ezikhethekile zokushisela; umshini wokudonsa inqwaba yokudlidliza we-hydraulic wokwenza ipuleti lensimbi; ukuhlanganiswa kwe-seal sluice kanye nokwelashwa ngopende wasefektri. Izici eziningana ziqinisekisa ukuthi inqwaba yeshidi ihlala ingenye yezingxenye zokukhiqiza eziwusizo kakhulu: ayigcini nje ngokuthuthukisa ikhwalithi yensimbi, kodwa futhi ikhuthaza ucwaningo kanye nentuthuko yemakethe yenqwaba yeshidi; Kuyasiza ukwenza ngcono ukwakheka kwezici zomkhiqizo futhi kuhlangabezane kangcono nezidingo zabasebenzisi.
Izinqwaba zensimbi ziyizingxenye ezinde zesakhiwo ezinezixhumanisi ezixhumene, ezivame ukusetshenziswa njengezindonga zokugcina ezakhiweni zasemanzini, ama-cofferdams, nezinye izinhlelo zokusebenza zokugcina inhlabathi noma amanzi. Zenziwe ngensimbi ukuze ziqine futhi ziqine, ukwakheka kwazo kokukhiya kwenza izindonga eziqhubekayo, zinikeze ukwesekwa okusebenzayo kokumba kanye namaphrojekthi esakhiwo.
Izinqwaba zensimbi ezibunjwe ngo-U ezakhiwe ngendlela ebandayo ensimbini i-S235, S275, noma i-S355, ubude obungu-6–18 m, zilungele ukugcinwa kwezindonga, ama-cofferdams, kanye nezisekelo.
LokhuIzinqwaba Zensimbi Ezinomumo Ongu-Uzakhiwe ngokubandayo ngokusekelwe ku-GB standard futhi zingatholakala ngamamaki aqinile aphezulu e-Q235b, Q345b, Q390 kanye ne-Q420. Zisetshenziselwa ukuqinisa izindonga, izisekelo, ama-cofferdams kanye neminye imisebenzi eminingi yobunjiniyela bokwakha futhi zihlinzekwa ngobude obusukela ku-6m kuya ku-18m. Umklamo we-Cold Formed U Pile unikeza ukujiya okulinganayo kanye nendlela yokuxhumanisa, ukuqina okuphezulu enhlabathini nasesimweni samanzi.
Uhlobo 2 lwe-Uukunqwabelanisa ishidi lensimbiiyinto esetshenziswa kabanzi ekubambeni umhlaba kanye nokusekela ukumba. Yenziwe ngensimbi enamandla amakhulu futhi inesigaba esinqunyiwe esinomumo we-U, enikeza ukuqina kwesakhiwo kanye nokuqina. Izinqwaba zamashidi e-U Type 2 zenzelwe ukuhlangana, zidala udonga oluqhubekayo lwezinhlelo ezahlukene zokwakha njengezakhiwo zasemanzini, ama-cofferdams, kanye nezindonga zokugcina. Ukuguquguquka kanye namandla okufakwa kwamashidi ensimbi e-U Type 2 kwenza kube ukukhetha okuthandwayo kwamaphrojekthi obunjiniyela bomphakathi adinga izixazululo zokugcina umhlaba ezisebenzayo nezithembekile.
Inqwaba yeshidi lensimbi elinohlobo lwe-Ziyisigaba sesakhiwo esisebenza kahle esithola ukusetshenziswa okubanzi kubunjiniyela bezakhiwo kanye nokwakhiwa kwezakhiwo. Isimo sasoInqwaba yeshidi lensimbi elinomfanekiso ka-Zkanye nokukhiya kwayo kunikeza ukumelana okukhulu komthwalo ohlangothini, ukuzinza nokuqina, yingakho zisetshenziselwa ukuqeqesha ukwakhiwa kwezindonga, udonga lwamanzi, amachweba, kanye nokumba okujulile ngaphandle komgwaqo.
Inqwaba yensimbi enomumo we-U egoqekile iklanyelwe ukufanela isidingo sesakhiwo esinzima kubunjiniyela bezakhiwo kanye nokusetshenziswa kwezakhiwo. Inamandla aphezulu futhi ingatholakala kumazinga e-SY295, SY390 kanye ne-SY490. Lawa manqwaba akhiqizwa ngokwezindinganiso ze-ASTM A328 kanye ne-JIS A5528 okuqinisekisa ukuthi amanqwabelano asezingeni eliphezulu.
Izinsimbi zensimbi ze-GB Q235B, Q345B, Q390, kanye ne-Q420 ziyizinsimbi zesakhiwo ezinamandla aphezulu ezisetshenziswa kabanzi ezakhiweni, emabhulohweni, ezindaweni zezimboni, kanye nasezinhlelweni zokusekela imithwalo esindayo.
