Ihlabathi lolwakhiwo kunye nobunjineli liye lavela ngokuphawulekayo kule minyaka idlulileyo, likhokelela kuphuhliso kunye nokusetyenziswa kweengcingo zentsimbi ezikumgangatho ophezulu zokuqinisa ikhonkrithi.Olunye ulutsha olunjalo luyi-prestressed steel concrete wire, eyaziwa ngokuba namandla akhethekileyo kunye nokuthembeka.Yenziwe kwi-carbon steel high-carbon steel hot-rolled wire rods, ezi ngcingo zetsimbi zifumana unyango lobushushu kunye nokusetyenzwa okubandayo ukufezekisa iimpawu ezifunwayo.Ngomxholo wekhabhoni ukusuka kwi-0.65% ukuya kwi-0.85% kunye ne-sulfure encinci kunye nomxholo we-phosphorus (ngaphantsi kwe-0.035%), olu hlobo locingo lwensimbi luhlangabezana neemfuno ezingqongqo zokuqiniswa kwekhonkrithi.
Namhlanje, iingcingo zentsimbi ezicinezelekileyo ziqhayisa ngamanqanaba okuqina okuchukumisayo, amandla angaphezulu kwe-1470MPa.Ngokuhamba kwexesha, amandla ezi ngcingo aye atshintsha ukusuka ikakhulu kwi-1470MPa kunye ne-1570MPa ukuya ikakhulu kwi-1670-1860MPa.Ngaphezu koko, ububanzi bezi ngcingo zentsimbi buye bavela, kunye nedayamitha eqhelekileyo ngokuthe ngcembe isuka kwi-3-5mm ukuya kwi-5-7mm.Oku kuqinisekisa ukomelela okwandisiweyo kunye nokusebenza kakuhle kwiiprojekthi ezahlukeneyo zokwakha, ukuqinisa ukuthembeka kolwakhiwo kumacandelo ekhonkrithi eyomeleziweyo.
Ukuguquguquka kweengcingo zentsimbi zekhonkrithi ezigxininisiweyo kuzenza zibe yimfuneko kuluhlu olubanzi lwezicelo zokwakha.Ezi ngcingo, kunye nemisonto yentsimbi ecinezelweyo eyenziwe kuzo, iye yaba zezona ntlobo zentsimbi zisetyenziswa kakhulu kwihlabathi jikelele.Ingaba izakhiwo zokuhlala okanye zorhwebo, iiprojekthi zezakhiwo ezifana neebhulorho kunye neetonela, okanye kunye nezakhiwo eziphakamileyo, ukusetyenziswa kweengcingo zetsimbi ezigxininisiweyo kuqinisekisa ukuthembeka okukhulu kunye namandla ekuqinisweni kwekhonkrithi.Ukukwazi kwabo ukumelana nemithwalo enzima, iziganeko zenyikima, kunye neemeko zemozulu ezimbi zibalaselisa indima yazo ebalulekileyo ekudaleni izakhiwo ezomeleleyo nezomeleleyo.
Ukuqukumbela, iingcingo zentsimbi ezicinezelekileyo ziye zaliguqula ishishini lokwakha.Ngamandla azo akhethekileyo, iinketho ezahlukeneyo zemveliso, kunye nokuqhelana nemilinganiselo eyahlukeneyo kunye neemfuno, ezi ngcingo ziye zaba yinxalenye yeeprojekthi zokwakha zale mihla kwihlabathi liphela.Inkqubela phambili eqhubekayo kunye nophuculo kwinkqubo yabo yokwenziwa inegalelo ngakumbi ekusetyenzisweni kwabo ngokubanzi kunye newonga njengomgangatho woshishino wokomelezwa kwekhonkrithi egxininisiweyo.
Njengoko iChina imveliso yesinyithi ekhokelayo kumashishini, urhwebo lwesizwe lwentsimbi kunye nezixhobo "Ikhulu leshishini elithembekileyo lokholo", amashishini entsimbi yaseTshayina, "amashishini abucala ali-100 aphezulu eShanghai". ) ithatha i" Integrity, Practicality, Innovation, Win-Win " njengomgaqo wayo wodwa wokusebenza, ihlala iphikelela ekubekeni imfuno yomthengi kwindawo yokuqala.
