Le projekthi yi-arched structure ye-Anyang yokugcina amalahle kunye nefreyimu yendawo yentsimbi.Ubude obupheleleyo bungama-558 eemitha, ubude buziimitha ezingama-77, kunye nobude obupheleleyo bungama-49 eemitha.
Isakhiwo sesakhelo sendawo kufuneka sibe ngokungqongqo ngokuhambelana nomgangatho woshishino "I-Steel Grid Bolt Ball Joint" JG/T10-2009.Izinto zentsimbi kufuneka zihlangabezane neemfuno zoyilo, kwaye ngokwemigangatho yesizwe yangoku "Inkcazo yoMgangatho woKwamkeleka koBunjineli beSteel Structure Construction" (GB50205-2020) zero Zonke izinto zenziwe kumzi-mveliso, kwaye zivavanywa yifektri ngokweempawu zomatshini kunye uhlalutyo lwekhemikhali, kwaye lunokusetyenziswa kuphela xa behlangabezana nemigangatho.Umphezulu wesakhiwo sensimbi yegridi kufuneka udutyulwe uqhunyiswe kwaye ususwe umhlwa, kunye nebanga le-Sa2.5.
Izinto zombhobho wensimbi ziya kuhambelana nentsimbi ye-Q235B echazwe kwi-GB700 ye "Carbon Structural Steel" kwaye iya kuhambelana nombhobho wensimbi odibeneyo ochazwe kwi-GB3092 okanye i-20 ye-seamless steel pipe echazwe kwi-GB3087.
Ibhola yebholithi yenziwe ngeNombolo ye-45 yentsimbi echazwe kwi-GB699, kwaye umphezulu kufuneka ube mpuluswa, kungabikho zintanda, kungabikho ukutshisa, kwaye akukho pitting.
Iibholiti eziphakamileyo eziphezulu zenziwe ngezinto ezichazwe kwi-GB / T16939-1997 "Iibhotshi eziphezulu zentsimbi yeentsimbi zegridi kunye neebhola zebhola".Imveliso egqityiweyo ayikuvumeli ukucima iintanda zaluphi na ubunzulu okanye naluphi na ubude kuyo nayiphi na indawo.Iibholiti eziphezulu zokuqina kwebhola edibeneyo "GB/T16939-1997" echazwe kwiimfuno zebakala, ubunzima bomhlaba kufuneka bufikelele kwi-HRC32 ~ 36, umsonto kufuneka uhlangabezane nenqanaba le-6g kwi-"General Thread Tolerance and Fit" GB197, umphezulu kufuneka zenziwe mnyama kwaye ziqatywe nge-Oli yokuchasa umhlwa.
Izinto eziphathekayo zepleyiti yokutywina kunye nentloko ye-cone iya kuhambelana ne-Q235 yensimbi echazwe kwi-GB700, kunye nempahla ye-sleeve iya kuhambelana nentsimbi ye-Q235 echazwe kwi-GB700 okanye i-16Mn yentsimbi echazwe "kwiMiqathango yobuGcisa kwiSimbi soLwakhiwo lwe-Low Alloy Structural Steel. " I-GB1591 okanye "iNtsimbi yeNsimbi yoLwakhiwo oluPhezulu lweCarbon".Inombolo ye-45 yensimbi echazwe kwi-GB699, ukubonakala kwepleyiti yokutywina, intloko ye-cone kunye nomkhono awuyi kuba nokuqhekeka, ukutshisa ngokugqithiseleyo kunye nesikali.
