(B125) EN124 Txoj Kev Gully Npog Round Ductile Hlau Manhole Npog thiab Ncej
Lub peev xwm ntawm lub manhole npog B125 yog 12,500 kg.
Raws li ib txwm muaj.Qhov chaw nruab nrab yog ntau tshaj 12.5 tons ntawm quab yuam thiab tseem tuaj yeem siv tau ib txwm, uas yog tus qauv ntawm EN124 B125.
Thiab B125 manhole npog tsim los ntawm peb lub Hoobkas tuaj yeem txhawb nqa + 5% siab.Ntawd yog, theoretically cia 15-tuj tsheb hla dhau.Thiab tshaj li lub neej ib txwm muaj rau ntau tshaj 5 xyoos.
Kev siv ntawm txoj kev qeeb tuaj yeem ua rau lub neej ua haujlwm ntau dua 10 xyoo.
Lub ductile hlau manhole npog muaj zoo toughness.Tus nqi cuam tshuam yog cov ncauj lus kom ntxaws nrog cov pa roj carbon nruab nrab, uas yog ntau tshaj 10 npaug ntawm cov khoom siv hlau grey.Muaj zog corrosion kuj.Nyob rau hauv cov dej tshuaj tsuag corrosion test, tus nqi ntawm corrosion nyob rau hauv 90 hnub tsuas yog 1/40 ntawm cov kav hlau thiab 1/10 ntawm cov kav hlau grey.Lub neej kev pabcuam yog ob zaug ntawm cov kav hlau grey thiab 5 npaug ntawm cov kav hlau zoo tib yam.Lub zog ntawm ductile hlau yog piv rau cov cam khwb cia hlau.Nodular cam khwb cia hlau muaj lub zog tawm los ntau dua, nrog qhov tsawg kawg nkaus lub zog ntawm 40k, thaum lub zog ntawm cov cam khwb cia hlau tsuas yog 36k.Hauv cov ntawv thov hauv nroog feem ntau, xws li dej, dej ntsev, chav dej, thiab lwm yam, kev tiv thaiv corrosion thiab oxidation tsis kam ntawm cov hlau ductile tshaj cov hlau cam khwb cia.Nodular cam khwb cia hlau manhole npog yog tsim los ntawm nodular cam khwb cia hlau.Qhov zoo ntawm no manhole npog muaj qhov teeb meem ntawm spheroidization tus nqi.Feem ntau siv cov xim rau castings yog anti-xeb asphalt xim.Ntawm chav kawm, qhov saum npoo ntawm cov hlau nplaum manhole npog kuj yog txau nrog cov xim pleev xim asphalt.Qhov kom zoo dua ntawm cov hlau hlau manhole npog yog vim muaj lub zog siab thiab tawv ntawm cov hlau hlau, cov hlau hlau manhole npog yog li 30% sib dua li grey cam khwb cia hlau manhole npog ntawm tib hom.
Yuav ua li cas xaiv ib tug manhole npog
1. (A15 hom): Cov hlua khi ntsuab, cov kev taug kev thiab lwm qhov chaw uas txwv tsis pub cov tsheb thauj mus los.
2. (B125 hom): kev taug kev, tsheb tsis muaj tsheb, tsheb nres tsheb thiab chaw nres tsheb hauv av.
3. (C250 hom): thaj chaw nyob, rov qab txoj kev thiab txoj kev, cov cheeb tsam uas tsuas yog lub teeb tsav tsheb lossis tsheb me me khiav, nyob rau hauv 0.5m ntawm curbs ntawm ob sab ntawm txoj kev.
4. (D400 hom): txoj kev hauv nroog arterial, txoj kev loj, kev nthuav dav thiab lwm qhov chaw.
5. (E600 hom): Cargo terminal, wharf, tshav dav hlau thiab lwm qhov chaw.
6. (F900 hom): tshav dav hlau khiav thiab lwm qhov chaw.
