ULarseninqwaba yeshiti yentsimbiIzakhiwo zenkxaso zisetyenziswa kakhulu kwiindlela zokwakha isiseko semigodi, ezaziwa ngokuba ziifenders. Ngenxa yeenkcukacha ezahlukeneyo zeenqwaba zesinyithi zaseLarsen kunye neendawo zazo ezibanzi zokusetyenziswa, iinqwaba zesinyithi zaseLarsen kufuneka zithuthwe ziye kwindawo yokwakha ngaphambi kokuba zisetyenziswe. , ngokubanzi bakhetha ukuthutha iinqwaba zesinyithi zaseLarsen ngemoto. Ukuba umgama mde kwaye imfuno inkulu, kuya kuba luncedo ngakumbi kwaye kukhawuleze ukuthumela iinqwaba zesinyithi zaseLarsen. IZiko loThutho laseJiaohang lisandul’ ukuqalisa ukuthutha amashumi amawaka eetoni zeenqwaba zesinyithi zaseLarsen ukusuka emnyango ukuya emnyango. Oku Phakathi kwazo kukho umba wendlela yokulayisha nokukhulula iinqwaba zesinyithi zaseLarsen ngokukhuselekileyo.
Umthamo ophezulu wokuthwala. Intsimbi inamandla aphezulu kwaye inokubethelelwa ngokufanelekileyo kwiindawo zomhlaba oqinileyo. Umzimba wenqwaba awonakalanga lula kwaye umthamo omkhulu wokuthwala inqwaba enye ungafumaneka. Umgangatho weprojekthi uthembekile kwaye isantya sokwakha siyakhawuleza. Ilula ngobunzima, inokuqina okuhle, kulula ukuyilayisha, ukuyithutha, ukuyithutha kunye nokuyifaka, kwaye ayonakalanga lula.
Iinqwaba zeshiti zentsimbisebenzisa intsimbi njengezinto ezisisiseko, ezivuseleleka kakhulu kwaye azivelisi inkunkuma eninzi yekhonkrithi kunye nezinye izinto ezingcolisa okusingqongileyo.
1. Ubude benqwaba kulula ukuyilungisa. Ubude benqwabaiinqwaba zeshiti zentsimbiingandiswa okanye inqunyulwe njengoko kufuneka.
2. Uqhagamshelo lwekhonkco lulula kakhulu. Lunokudityaniswa nge-electric welding, okulula ukuyisebenzisa, lunamandla kwaye lukhuselekile ukuyisebenzisa.
3. Ubungakanani bomhlaba oshiyweyo buncinci kwaye abunampembelelo ingako kwizakhiwo ezikufutshane (izakhiwo). Ngenxa yokuvulwa komphetho osezantsi wenqwaba, umhlaba uya kucinezelwa kwityhubhu yenqwaba xa inqwaba iqhutywa. Xa kuthelekiswa neenqwaba zokwenyani, ubungakanani bomhlaba ocinezelweyo buncitshiswa kakhulu, nto leyo ebangela ukuphazamiseka okuncinci kwisiseko esijikelezileyo, kuthintelwe ukuphakanyiswa komhlaba, kwaye kunciphisa kakhulu imiphumo yokushenxa ngokuthe nkqo kunye nokushenxa komphezulu wenqwaba ngokuthe tye.
Iinqwaba zeshiti zentsimbiingasetyenziswa njengenye yeendlela zobuchwepheshe zokwakha ulwakhiwo lobunjineli besiseko, kwaye zifanelekile kwiindawo ezisisiseko zeeprojekthi ezahlukeneyo zokwakha, ezinje ngezakhiwo zangaphantsi, izakhiwo zesakhelo, ingaphandle lendlu, njl.
Izakhiwo zentsimbi ezikumgangatho ophezulu zihambelana nemigangatho ye-ASTM, azinamhlwa kwimozulu yetropiki. Izisombululo ezenziwe ngokwezifiso.
Izakhiwo zentsimbiezikumgangatho ophezulu zifanelekile ngokwemigangatho ye-ASTM, kwimozulu yetropiki enokumelana nokugqwala okuphezulu.
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
Ngokukhula koqoqosho lwaseTshayina, ukusebenza okuphezulu kwenqwaba yesinyithi esijikeleziweyo esishushu kuyathandwa ngabantu abaninzi, kwayeinqwaba yeshidi lesinyithi eligoqiweyo elishushuiza kuphuhliswa ngokubanzi kwixesha elizayo. Kunye netekhnoloji yokuvelisa inqwaba yesinyithi esigoqiweyo esishushu.
Uhlobo lwe-U olushushu oluqengqelekayoInqwaba yePhepha leNsimbis, njengezinto zokwakha ezintsha, ingasetyenziswa njengokugcina umhlaba, ukugcina amanzi kunye nodonga lokugcina isanti ekwakhiweni kwebhulorho iCofferdam, ukubeka imibhobho emikhulu kunye nokumba imijelo yexeshana. Idlala indima ebalulekileyo kubunjineli obufana nodonga lokugcina, udonga lokugcina kunye nokukhusela i-embankment kwi-wharf kunye neyadi yokukhupha impahla. Inqwaba yesinyithi yeLarsen njengeCofferdam ayigcini nje ngokuba luhlaza, ukhuseleko lokusingqongileyo, kodwa ikwakhawuleza kakhulu ukwakhiwa, iindleko eziphantsi zokwakha, kwaye inomsebenzi omhle wokungangeni manzi.
Njengezixhobo ezisetyenziswa rhoqo kwiziseko zophuhliso, indima ephambili yeenqwaba zesinyithi kukwenza inkqubo yokuxhasa emhlabeni ukuxhasa ubunzima bezakhiwo okanye ezinye izakhiwo. Kwangaxeshanye, iinqwaba zesinyithi zingasetyenziswa njengezixhobo ezisisiseko kwizakhiwo zobunjineli ezifana nee-cofferdams kunye nokukhuselwa kwethambeka. Iinqwaba zesinyithi zesinyithi zisetyenziswa kakhulu ekwakheni, ekuthuthweni, ekugcinweni kwamanzi, ekukhuselweni kwendalo nakwezinye iindawo.
Intsimbi ye-C-channel yenkxaso ye-photovoltaic luhlobo lwesakhiwo senkxaso esisetyenziswa kakhulu kwinkqubo yokuvelisa umbane ye-photovoltaic, eneempawu ezininzi eziphawulekayo. Okokuqala, uyilo lwecandelo lentsimbi ye-C-channel lwenza ukuba ibe nokumelana okuhle kokugoba nokucheba, kwaye inokumelana ngempumelelo nobunzima kunye nomthwalo womoya weemodyuli ze-photovoltaic, ukuqinisekisa uzinzo kunye nokhuseleko lwenkqubo. Ukuguquguquka kwe-C-channel kuyenza ifaneleke kwiintlobo ezahlukeneyo zeenkqubo ze-photovoltaic, nokuba zifakwe emhlabeni okanye eluphahleni, zibonelela ngenkxaso ethembekileyo.
