Plain, Kauv Rib thiab Indented PC Strand (2 xov hlau, 3 xov hlau thiab 7 xov hlau)
Nyob rau hauv Suav teb, Silvery Dragon feem ntau muab nws 7 xov hlau dawb strand rau txoj kev loj thiab kev kub ceev railway choj kev lag luam.Txij li thaum Beijing-Tianjin inter-lub nroog cov neeg caij tsheb tau pib xyoo 2005, Silvery Dragon tau muab 550, 000 strands rau ntau tshaj 20 txoj haujlwm nrog tag nrho ntev ntawm 6000km suav nrog Zhengzhou-Xian, Harbin-Dalian, Beijing-Shanghai, Shijiazhuang-Taiyuan, Beijing-Shijiazhuang, Shijiazhuang-Wuhan, Tianjin-Qinhuangdao, lub nplhaib sab hnub tuaj hauv Hainai nroog thiab lwm yam.Peb kuj muaj kev ua haujlwm zoo hauv kev tsim kho 300-400km / h high-speed railway.Lub caij no, peb xa tawm ntau rau cov haujlwm loj hauv txawv teb chaws, xws li Kuwait Jaber Causeway Project hauv Kuwait, Edmonton Ring Expressway hauv Canada, GLP Nagareyama III Project hauv Nyiv, Tel Aviv mus rau Yeluxalees railway hauv Ixayees thiab lwm yam.
Indented thiab kauv rib PC strand yog tsim rau pre-stressed pob zeb engineering uas yuav tsum tau muaj zog bonding quab yuam thiab luv luv pre-stress hloov mus ntev.Nws yog tsuas yog siv rau hauv kev tiv thaiv txoj kab nqes, kev tiv thaiv geological thiab kev txhawb nqa kuv.Lawv tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm PrEN10138, BS5896, ASTMA886, JISG3536, KSD7002, thiab lwm yam Kauv Rib PC strand yog ib yam khoom tshiab tsim los ntawm peb lub tuam txhab.Nws cov xov hlau sab nraud yog cov hlua khi hlua khi thiab cov xaim hauv nruab nrab yog cov kab dawb puag ncig nrog kom zoo dua lub zog tensile, zoo plasticity, muaj zog anchoring muaj peev xwm thiab zoo dua daim ntawv cog lus-muaj peev xwm nrog pob zeb.Nws yog thawj qhov kev xaiv rau txoj kev txhawb nqa thiab txoj kab nqes kev sib koom ua ke.
