I. Qauv:
- EN124 yog tus qauv tseem ceeb nyob sab Europe rau manhole npog. Hauv xyoo 2017, nws tau tawg ua rau 6 sub- cov qauv, qhia cov kev xav tau rau cov qauv, kev ua haujlwm, thiab kev kos npe, hloov cov qauv qub BS497.
- Qib C250: Test load Ntau dua los yog sib npaug li 250kN (25 tons), haum rau txoj kev ntws kwj dej thiab cov ntug kev tsheb (txuas tsawg dua lossis sib npaug li 0.5 meters rau hauv txoj kev tsheb, Tsawg dua lossis sib npaug li 0.2 meters rau hauv kev taug kev).
- Tag nrho cov khoom raug thauj mus los thiab qhov ntsuas qhov sib txawv ntawm lub Hoobkas, ua raws li EN124 thiab GB6414-86 CT12 cov cai, nrog cov cim meej qhia cov ntaub ntawv tseem ceeb.
II. Khoom siv
Khoom yam ntxwv:
Los ntawm spheroidization thiab inoculation kev kho mob, cov graphite yog kheej kheej, nrog lub zog tensile Ntau dua los yog sib npaug rau 420MPa, yield zog Ntau dua los yog sib npaug rau 300MPa, cuam tshuam toughness mus txog qhov nruab nrab carbon steel, thiab corrosion kuj deb tshaj ntawm grey hlau thiab zoo tib yam hlau.
Qhov zoo:
Kev pab lub neej tshaj 20 xyoo (ob zaug ntawm grey hlau manhole npog), superior poob siab thiab suab nrov txo piv rau cam khwb cia hlau, hloov mus rau av noo, acidic, thiab alkaline underground ib puag ncig.
Kev Tswj Xyuas Zoo:
Ua tib zoo xaiv cov ntaub ntawv raw yog ua ke nrog tus neeg sawv cev tshwj xeeb spheroidizing, ua haujlwm siab -kub smelting, kev kho cua sov, thiab ntau yam tshuaj xyuas kom tshem tawm cov teeb meem sab hauv.
III. Tus Qauv Tsim
Square Structure
- Adaptability:Fits square/irregular manhole opens (cable manholes, kev sib txuas lus manholes, thiab lwm yam), txo qhov chaw pov tseg thiab tiv thaiv cov khib nyiab ingress.
-Specifications:Feem ntau 500 × 500mm-800 × 800mm, customizable; thickness 35-50mm, ib txheej hnyav 35-80kg, ntsuas lub zog thiab yooj yim ntawm kev tuav.
Xauv Ntaus Ntaus
- Qauv:Symmetrical ob lub qhov tseem ceeb + ua tau -hauv lub xauv ncej, L- tus nplaig xauv, tus yuam sij siab siab - tsav xauv, hloov kho raws li kev xav tau.
- Anti- tub sab zoo:Daim duab peb sab xauv lub taub hau rau kev tiv thaiv cuav, zais tus pin ob qhov kev tiv thaiv, kev sib xyaw ua haujlwm zoo hauv paus rau kev tiv thaiv tub sab tag nrho, xauv nrog tib lub neej ntev li lub cev loj.
IV. Kev ua tau zoo
Load-cov kabmob thiab cuam tshuam
Tshaj 25 tons kev puas tsuaj, qee qhov chaw ncav cuag 360KN tus qauv, tuaj yeem tiv taus lub zog crushing ntawm lub teeb tsheb, siab toughness los tiv thaiv brittle puas.
Sealing thiab tiv thaiv kom tsis txhob tawg
Rubber sealing nplhaib seals, thaiv cov khib nyiab, tiv thaiv cov ntxhiab tsw, cuam tshuam tsis zoo thiab txo cov suab nrov.
Durability
xeb- pov thawj kev kho deg, haum rau ob qho tib si sab qaum teb thiab yav qab teb huab cua, tsis tshua muaj kev hloov zaus, tus nqi tu qis.
V. Application Scenarios
Municipal Road Edges:
Cov dej ntws tawm raws txoj kev loj thiab theem nrab, haum rau lub teeb tsheb thiab cov neeg taug kev.
Industrial Parks thiab cov zej zog:
Ntug ntawm txoj kev thiab chaw nres tsheb hauv cov zej zog cov zej zog thiab cov chaw ua si, ntsuas kev nyab xeeb thiab kev tiv thaiv.
Chaw Ua Lag Luam Pej Xeem:
Txoj kev lag luam, chaw ua si, tsev kawm ntawv; kev tiv thaiv tub sab nyiag kom muaj kev nyab xeeb rau pej xeem.
Telecommunications thiab Fais fab Sector:
Cable manholes, tu manholes; tiv thaiv tub sab nyiag thiab kev tsim txom.
VI. Kev txhim kho thiab tu
Cov ntsiab lus tseem ceeb ntawm Installation
Ua ntej- kho qhov qhib qhov manhole thiab txhawb nqa lub hauv paus; calibrate qib kom yaug nrog av; kho lub hauv paus manhole; ceev lub nplhaib sealing; kuaj lub load thiab xauv muaj nuj nqi tom qab ua tiav.
Kev tu txhua hnub
Tsis tu ncua ntxuav qhov chaw, lubricate lub xauv, kho tam sim ntawd deformed los yog puas qhov chaw; siv tus yuam sij tshwj xeeb los qhib lub xauv kom tsis txhob muaj kev puas tsuaj loj.
VII. Summary and Selection Recommendations
Qhov zoo:
Standardized load-cov kabmob muaj peev xwm, siab ntev, tiv thaiv-kev ruaj ntseg tub sab nyiag, siv dav, tsis tshua muaj nqi tu.
Cov tswv yim xaiv:
Rau cov tsheb loj / cov tsheb hnyav, xaiv D400 lossis qib siab dua; ua ntej cov khoom ua raws nrog cov ntawv xeem; xaiv raws li manhole qhib loj.
