I-prestressed steel concrete wire yintsimbi yentsimbi ekumgangatho ophezulu eyenziwe kwi-high-carbon steel hot-rolled wire rods, ephathwa ngobushushu kwaye iqhutywe ngokubanda. Yenzelwe ngokukodwa ukuhlangabezana neemfuno zokuqiniswa kwekhonkrithi egxininisiweyo.
Amandla okuqina ocingo lwentsimbi yekhonkrithi ecinezelekileyo angaphezulu kwe-1470MPa. Ngokuhamba kwexesha, amanqanaba okuqina atshintshe ukusuka kwi-1470MPa kunye ne-1570MPa ukuya kuluhlu oluqhelekileyo lwe-1670MPa ukuya kwi-1860MPa. Idayamitha yocingo nayo itshintshile, ukusuka kwi-3 ~ 5mm yokuqala ukuya kumgangatho wangoku we-5 ~ 7mm. Ezi nkcukacha ziqinisekisa ukuqina kunye nokuthembeka kocingo lwensimbi ekumelaneni noxinzelelo kunye neemfuno zomthwalo wezakhiwo zekhonkrithi ezigxininisiweyo.
Umxholo wekhabhoni wolu hlobo locingo lwensimbi luyi-0.65% ukuya kwi-0.85%, kwaye iziqulatho zesulfure kunye ne-phosphorus ziphantsi, zombini ngaphantsi kwe-0.035%. Ukususela ekuvelisweni kwayo kwimizi-mveliso kunye nokusetyenziswa kwayo kwiminyaka yee-1920, ucingo lwensimbi olune-prestressed luye lwafumana amashumi eminyaka yophuhliso, olukhokelela kuluhlu lweemveliso ezifanelekileyo kwiinkqubo ezahlukeneyo. Oku kuquka ucingo olutsalwa ngokubanda, ucingo olululiweyo nolupholileyo, ucingo olupholileyo olusezantsi, ucingo olufakwe amazinki kunye nocingo olunamanqaku. Iingcingo zentsimbi ezicinezelekileyo kunye neentambo zentsimbi ezenziwe ngoxinzelelo ezenziwe kuzo ziye zaba zezona ntlobo zentsimbi ezisetyenziswa kakhulu kwihlabathi.
Ucingo lwekhonkrithi olugxininisiweyo luneempawu ezininzi eziphambili ezenza ukuba zilungele ukuqinisa izakhiwo zekhonkrithi. Amandla ayo aphezulu kunye nokuchasana nokuguqulwa kuqinisekisa ukuba inokumelana nemithwalo ebalulekileyo kwaye igcine ingqibelelo yesakhiwo. Ukongeza, iipropathi zokuphumla ezisezantsi zeentlobo ezithile zocingo olucinezelayo zinciphisa ukulahleka koxinzelelo ngokuhamba kwexesha. Oku kunceda ukugcina uzinzo lwesakhiwo sekhonkrithi. Iintlobo ezahlukeneyo zocingo, ezinje ngegalvanized kunye namanqaku, zibonelela ngeempawu ezongezelelweyo ezifana nokuphuculwa kokuxhathisa kokutya okanye ukomelela okungcono kwebhondi.
Iingcingo zekhonkrithi ezigxininisiweyo zihlelwa kwiindidi ezahlukeneyo ngokusekelwe kwiimpawu kunye nokusetyenziswa kwazo. Ezi ziquka i-low-relaxation serrated PC wire, ephucula ukuhanjiswa koxinzelelo kunye nokunciphisa iimpawu zokuphumla. Olunye ulwahlulo lusekwe kububanzi bocingo, olunokhetho olususela kwi-2.64mm ukwenzela izicelo ezithambileyo ukuya kwiidayamitha ezinkulu kwiiprojekthi zokwakha ezinzima.
Ucingo lwekhonkrithi olucinezelekileyo lusetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zokwakha. Isetyenziswa kakhulu ekwakhiweni kweebhulorho, ii-viaducts, izakhiwo eziphakamileyo kunye nezinye izakhiwo ezinkulu ezifuna ukunyuswa komthwalo wokuthwala. Ukukwazi kocingo ukumelana noxinzelelo kunye nokuxhathisa uxinzelelo kwenza kube yinto efanelekileyo yokuqinisa amalungu ekhonkrithi. Ikwasetyenziselwa ukuveliswa kweemveliso zekhonkrithi zangaphambili, iinkqubo ze-post-tensioned, kunye neenkqubo ze-anchoring emhlabeni apho izinto ezithembekileyo nezizinzileyo zifunekayo. Ngokusisiseko, iingcingo zekhonkrithi ezicinezelekileyo zibalulekile ekuqinisekiseni ukomelela kolwakhiwo kunye nobomi obude bezakhiwo ezahlukeneyo zekhonkrithi.
Isicelo
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.
