Ucingo lwentsimbi oluqinileyo lwekhonkrithi lucingo lwentsimbi olukumgangatho ophezulu olwenziwe ngeentonga zentsimbi ezitshisiweyo zentsimbi enekhabhoni ephezulu, ezinyangwa ngobushushu kwaye zicocwe. Zenzelwe ngokukodwa ukuhlangabezana neemfuno zokuqinisa ikhonkrithi exineneyo.
Amandla okutsalwa kwentambo yentsimbi yekhonkrithi exineneyo ngokubanzi angaphezulu kwe-1470MPa. Ngokuhamba kwexesha, amanqanaba okuqina atshintshe ukusuka kwi-1470MPa kunye ne-1570MPa ukuya kuluhlu oluqhelekileyo lwe-1670MPa ukuya kwi-1860MPa. Ububanzi bentambo butshintshile, ukusuka kwi-3 ~ 5mm yokuqala ukuya kumgangatho wangoku we-5 ~ 7mm. Ezi nkcukacha ziqinisekisa ukuqina kunye nokuthembeka kwentambo yentsimbi ekumelaneni neemfuno zoxinzelelo kunye nomthwalo wezakhiwo zekhonkrithi ezixineneyo.
Umxholo wekhabhoni wolu hlobo lwentambo yentsimbi yi-0.65% ukuya kwi-0.85%, kwaye umxholo wesalfure kunye ne-phosphorus uphantsi, zombini zingaphantsi kwe-0.035%. Ukususela ekuvelisweni nasekusetyenzisweni kwayo kwimizi-mveliso ngeminyaka yoo-1920, ucingo lwentsimbi oluxinzelelweyo luye lwanamava eminyaka yophuhliso, nto leyo ebangele uluhlu lweemveliso ezifanelekileyo kwiintlobo ngeentlobo zezicelo. Ezi ziquka ucingo olutsalwa ngokubandayo, ucingo oluqondileyo noluthambileyo, ucingo oluphumlayo oluphantsi, ucingo olugqunyiweyo kunye nocingo olunezikhonkwane. Iingcingo zentsimbi ezixinzelelweyo kunye nemicu yentsimbi exinzelelweyo eyenziwe ngazo ziye zaba zezona ntlobo zentsimbi ezixinzelelweyo ezisetyenziswa kakhulu kwihlabathi liphela.
Ucingo lwekhonkrithi oluxinzelelweyo luneempawu ezininzi ezibalulekileyo ezenza ukuba lufanelekele ukuqinisa izakhiwo zekhonkrithi. Amandla alo aphezulu okuxinana kunye nokumelana nokuguquguquka kuqinisekisa ukuba lunokumelana nemithwalo ebalulekileyo kwaye lugcine ukuthembeka kwesakhiwo. Ukongeza, iimpawu zokuphumla okuphantsi kweentlobo ezithile zentambo yoxinzelelweyo zinciphisa ukulahleka koxinzelelo ngokuhamba kwexesha. Oku kunceda ukugcina uzinzo lwesakhiwo sekhonkrithi. Iindidi ezahlukeneyo zentambo, ezifana ne-galvanized kunye ne-scored, zibonelela ngeempawu ezongezelelweyo ezifana nokumelana nokugqwala okuphuculweyo okanye amandla angcono okubopha.
Iingcingo zekhonkrithi ezixineneyo zahlulwe ngokweentlobo ezahlukeneyo ngokusekwe kwiimpawu zazo kunye nokusetyenziswa kwazo. Ezi ziquka iingcingo zePC ezithambileyo neziphumlayo, eziphucula ukudluliselwa koxinzelelo kwaye zinciphise iimpawu zokuphumla. Olunye udidi lusekelwe kububanzi bengcingo, kunye neendlela ezahlukeneyo ukusuka kwi-2.64mm zokusetyenziswa okubuthathaka ngakumbi ukuya kububanzi obukhulu kwiiprojekthi zokwakha ezinzima.
Ucingo lwekhonkrithi oluxinzelelweyo lusetyenziswa kakhulu kwiiprojekthi ezahlukeneyo zokwakha. Lusetyenziswa kakhulu ekwakhiweni kweebhulorho, ii-viaducts, izakhiwo eziphakamileyo kunye nezinye izakhiwo ezinkulu ezifuna amandla aphuculweyo okuthwala umthwalo. Amandla entambo okumelana noxinzelelo noxinzelelo enza ukuba ilungele ukuqinisa amalungu ekhonkrithi. Lukwasetyenziswa ekwenziweni kweemveliso zekhonkrithi ezilungisiweyo, iinkqubo ezixinzelelweyo emva koxinzelelo, kunye neenkqubo zokubambelela emhlabeni apho kufuneka khona izinto zokuqinisa ezinokuthenjwa nezihlala ixesha elide. Ngokuyintloko, ucingo lwekhonkrithi oluxinzelelweyo lubalulekile ekuqinisekiseni amandla esakhiwo kunye nobude bexesha bezakhiwo ezahlukeneyo zekhonkrithi.
Isicelo
Njengoko ishishini lezinto zesinyithi laseTshayina likhokela amashishini, urhwebo lwesizwe lwentsimbi kunye ne-logistics "Ikhulu leenkampani ezilungileyo", amashishini orhwebo lwentsimbi laseTshayina, "Amashishini abucala ali-100 aphezulu eShanghai". I-Shanghai Zhanzhi industry Group Co., Ltd., (efinyezwe kwi-Zhanzhi Group) ithatha "Ingqibelelo, ukuSebenza, ukuVula, ukuPhumelela" njengomgaqo wayo wokusebenza, ihlala iqhubeka nokubeka iimfuno zabathengi kwindawo yokuqala.
