Intambo yensimbi yekhonkrithi eqinisiwe iyintambo yensimbi yekhwalithi ephezulu eyenziwe ngezinduku zensimbi ezigoqwayo ezishisayo zensimbi enekhabhoni ephezulu, eziphathwa ngokushisa futhi zicutshungulwe zibanda. Yenzelwe ngokukhethekile ukuhlangabezana nezidingo zokuqinisa ikhonkrithi eqinisiwe.
Amandla okuthamba kwentambo yensimbi yekhonkrithi ecindezelwe ngokuvamile angaphezu kuka-1470MPa. Ngokuhamba kwesikhathi, amazinga okuqina ashintshe kusuka ku-1470MPa kanye no-1570MPa kuya ebangeni elivamile kakhulu le-1670MPa kuya ku-1860MPa. Ububanzi bentambo nabo bushintshile, kusukela ku-3~5mm yokuqala kuya emazingeni amanje angu-5~7mm. Lezi zincazelo ziqinisekisa ukuqina nokuthembeka kwentambo yensimbi ekubhekaneni nezidingo zokucindezeleka kanye nomthwalo wezakhiwo zekhonkrithi ezicindezelwe.
Okuqukethwe kwekhabhoni kwalolu hlobo lwensimbi yensimbi kungu-0.65% kuya ku-0.85%, kanti okuqukethwe kwe-sulfur ne-phosphorus kuphansi, kokubili kungaphansi kuka-0.035%. Kusukela ekukhiqizweni nasekusetshenzisweni kwayo kwezimboni ngawo-1920, insimbi yensimbi ecindezelwe iye yathuthukiswa amashumi eminyaka, okuholele emikhiqizweni eyahlukahlukene efanelekile. Lokhu kufaka phakathi intambo edonswayo ebandayo, intambo eqondile nethambile, intambo yokuphumula ephansi, intambo ye-galvanized kanye nentambo eqoshiwe. Izintambo zensimbi ezicindezelwe kanye nezintambo zensimbi ezicindezelwe ezenziwe ngazo sezibe yizinhlobo zensimbi ezicindezelwe ezisetshenziswa kakhulu emhlabeni.
Ucingo lwekhonkrithi olucindezelwe lunezici eziningana ezibalulekile ezenza lufanelekele ukuqinisa izakhiwo zekhonkrithi. Amandla alo aphezulu okubamba kanye nokumelana nokuguquguquka kuqinisekisa ukuthi lingakwazi ukumelana nemithwalo emikhulu futhi ligcine ubuqotho besakhiwo. Ngaphezu kwalokho, izici zokuphumula eziphansi zezinhlobo ezithile zezintambo ezicindezelayo zinciphisa ukulahleka kokucindezeleka ngokuhamba kwesikhathi. Lokhu kusiza ukugcina ukuzinza kwesakhiwo sekhonkrithi. Izinhlobo ezahlukene zezintambo, njenge-galvanized kanye ne-scored, zinikeza izici ezengeziwe njengokumelana nokugqwala okuthuthukisiwe noma amandla esibopho angcono.
Izintambo zikakhonkolo ezicindezelwe zihlukaniswa ngezinhlobo ezahlukene ngokusekelwe ezicini zazo kanye nokusetshenziswa kwazo. Lokhu kufaka phakathi intambo ye-PC ethambile ephumuzayo, ethuthukisa ukudluliselwa kokucindezeleka futhi inciphise izici zokuphumula. Okunye ukuhlukaniswa kusekelwe kububanzi bentambo, ngezinketho ezisukela ku-2.64mm zezicelo ezithambile kuya kububanzi obukhulu bemisebenzi yokwakha esindayo.
Ucingo lwekhonkrithi olucindezelwe lusetshenziswa kabanzi kumaphrojekthi ahlukahlukene okwakha. Lusetshenziswa kakhulu ekwakhiweni kwamabhuloho, ama-viaducts, izakhiwo eziphakeme kanye nezinye izakhiwo ezinkulu ezidinga amandla athuthukisiwe okuthwala umthwalo. Amandla entambo okubekezelela ukucindezelwa nokumelana nokucindezeleka enza kube kuhle kakhulu ekuqiniseni amalungu ekhonkrithi. Lusetshenziswa futhi ekwenziweni kwemikhiqizo yekhonkrithi eqinisiwe, izinhlelo ezicindezelwe ngemva kokucindezeleka, kanye nezinhlelo zokuqinisa umhlabathi lapho kudingeka khona izinto zokuqinisa ezithembekile nezihlala isikhathi eside. Empeleni, izintambo zekhonkrithi ezicindezelwe ngaphambi kokucindezeleka zibalulekile ekuqinisekiseni amandla esakhiwo kanye nobude besikhathi bezakhiwo ezahlukene zekhonkrithi.
Isicelo
Njengoba imboni yezinto zensimbi yaseShayina ihamba phambili embonini, ukuhweba ngensimbi kanye ne-logistics kuzwelonke "ibhizinisi elikhulu elinokwethembeka okuhle", amabhizinisi okuhweba ngensimbi yaseShayina, "amabhizinisi azimele ayi-100 aphezulu eShanghai". I-Shanghai Zhanzhi industry Group Co., Ltd., (efinyeziwe ku-Zhanzhi Group) ithatha "Ubuqotho, Ukusebenza, Ukusungula Izinto Ezintsha, Ukunqoba" njengomgomo wayo wokusebenza kuphela, ihlala iqhubeka nokubeka isidingo samakhasimende endaweni yokuqala.
