GOST 3634 ductile hlau manhole npog yog hais txog ib hom kev siv npog tsim nyob rau hauv kev ua raws li Russia lub teb chaws tus qauv GOST 3634 (tshwj xeeb yog rau cov khoom siv hlau cam khwb cia siv hauv nroog infrastructure). Nws yog ib qho hnyav -cov dej ua haujlwm hlau (nodular cam khwb cia hlau) cov khoom tsim los rau kev nkag mus rau hauv av hauv tebchaws Russia thiab CIS (Commonwealth of Independent States) lub teb chaws, siv dav hauv txoj kev tsheb thauj mus los, cov kav dej hauv nroog, thiab kev sib tham hauv JRC.

Cov txheej txheem no txhais cov ntsiab lus tseem ceeb rau cov khoom siv zoo, kev ua haujlwm zoo, thiab kev nyab xeeb ntawm cov qauv, kom ntseeg tau tias muaj kev sib raug zoo nrog Russia cov qauv kev tsim kho vaj tse thiab kev nyab xeeb.

Cov yam ntxwv tseem ceeb ntawm GOST 3634 Ductile Iron Manhole Npog

Cov khoom siv nruj & Mechanical Performance Requirements

Ductile Iron Specification: Txais Lavxias- qauv cov qib hlau hlau (analogous rau QT500-7 hauv cov qauv thoob ntiaj teb), nrog cov ntsiab lus carbon tswj ntawm 3.5-3.9%, silicon ntawm 2.2-2.8%, thiab magnesium ntawm 0.03-0.05%, kom ruaj khov nodular graphite qauv
Mechanical Thresholds: Tensile zog Ntau dua los yog sib npaug rau 450MPa, elongation Ntau dua los yog sib npaug rau 6% (hloov me ntsis los ntawm EN124's 500MPa / 7% kom haum rau cov khoom siv hauv zos), thiab cuam tshuam toughness Ntau dua los yog sib npaug rau 15J ntawm -20℃(tshaj rau thaj tsam ntawm Russia).

Kev nyab xeeb-Adapted Design

Tsawg-Qhov Kub Ua Haujlwm: Cov khoom siv tau zoo tshaj plaws thiab cov txheej txheem kev kho cua sov txo qhov kev pheej hmoo ntawm pob txha tawg nyob rau hauv ib puag ncig khov (nrog rau Siberia thiab sab qaum teb Russia). Tsis zoo li tus qauv EN124 npog, nws yuav tsum tau ntsuas -30℃kev cuam tshuam los xyuas kom muaj kev ruaj ntseg ruaj khov ntau dua lossis sib npaug li 70%.
Sealing & Corrosion Protection: Nruab nrog Frost -cov roj hmab roj hmab tiv taus (tiv taus rau -40℃embrittlement) thiab zinc-aluminium alloy txheej, hais txog kev xeb los ntawm txoj kev deicing ntsev thiab dej hauv av.

Scenario-Raws li Load Classification

Muab faib los ntawm daim ntawv thov scenarios es tsis yog cov nqi thauj khoom dawb huv:
Cheeb tsam neeg taug kev (P chav kawm): Rau txoj kev taug kev thiab txoj siv sia ntsuab, thauj khoom -cov kabmob loj dua lossis sib npaug rau 15kN (sib npaug rau EN124 A15).
Txoj Kev Teeb (Д chav kawm): Rau txoj kev nyob hauv tsev, thauj khoom - bearing Ntau dua lossis sib npaug rau 125kN (sib npaug rau EN124 B125).
Hnyav Txoj Kev (Т chav kawm): Rau txoj kev loj thiab thaj chaw muaj kev lag luam, thauj khoom -cov kabmob loj dua lossis sib npaug rau 400kN (raws li EN124 D400, ua raws li koj daim ntawv tshuaj xyuas D400 chav kawm xav tau).

Cov qauv kev nyab xeeb tsom

Anti-Kev Tsim Kho: Lub thav duab tau txais cov qauv "dav flange" nrog rau qhov tob tob Ntau dua lossis sib npaug li 35mm (dhau EN124 tus qauv 30mm), tiv thaiv kev poob hauv qab lub tsheb ntau dua.
Tamper-Resistant Locking: Standardized rotating locking mechanisms (es tsis yog EN124's common bolted locks) kom hloov mus rau Russia txoj kev tiv thaiv - tub sab infrastructure xav tau.
