I. Specifications
Specification Coverage: Mainstream diameters muaj xws li DN600, DN700, DN800, DN900, thiab DN1000, feem ntau puag ncig (rau txawm tias kev ntxhov siab faib thiab sib haum nrog ntau hom manhole). Square designs muaj rau qee qhov kev siv. Dimensional tolerances yog nruj me ntsis tswj: txoj kab uas hla deviation Tsawg tshaj los yog sib npaug zos rau ± 2 hli, vaj huam sib luag flatness Tsawg tshaj los yog sib npaug zos rau 1 hli, xyuas kom meej flush alignment nrog txoj kev nto.
Loj Matching: Lub manhole npog qhov loj me sib npaug ntawm lub manhole chamber txoj kab uas hla. Piv txwv li, DN1000 manhole npog sib haum rau lub manhole npog phaj loj ntawm kwv yees li 1360mm, yoog raws cov kev xav tau ntawm cov kav dej hauv av nrog cov kab sib txawv thiab ua raws cov qauv tsim hauv nroog.
II. Khoom siv thiab kev tsim qauv
Cov ntaub ntawv tseem ceeb: Rau kev siv hauv nroog thiab hnyav- cov haujlwm ua haujlwm, cov hlau nplaum (QT450-10/QT500-7) yog qhov nyiam, ua raws li GB/T 1348-2020 tus qauv. Tensile zog Ntau dua los yog sib npaug rau 420MPa, elongation Ntau dua los yog sib npaug rau 7%, thiab corrosion kuj 1/5-1/8 ntawm grey cam khwb cia hlau yog yuav tsum tau. Rau cov ntawv thov tshwj xeeb, cov khoom siv los tiv thaiv corrosion (kub-dip galvanized, epoxy txheej) lossis cov ntaub ntawv pob zeb tuaj yeem kho.
Structure: Lub vaj huam sib luag nta los tiv thaiv-slip textures Ntau dua lossis sib npaug ntawm 2 hli sib sib zog nqus (qhuav kev sib txhuam coefficient Ntau dua lossis sib npaug rau 0.6), nrog crisscrossing lossis radial reinforcing tav nyob rau hauv qab. Cov npoo yog inlaid nrog EPDM roj hmab strips los tiv thaiv dej seepage. Lub thav duab muaj lub nplhaib -zoo li tus txhawb nqa platform los faib cov khoom thauj. Qee cov qauv tau tsim- nyob rau hauv lub caij nplooj ntoos hlav clips lossis tiv thaiv - tub sab bolts los tiv thaiv kev txav chaw, suab nrov, thiab tub sab.
III. Load-Bearing Capacity Classification
Qib C250
Tau tshaj DN600-DN700 specifications, siv nyob rau hauv tej thaj chaw, kev taug kev, thiab lwm qhov chaw uas tsuas yog lub teeb lub tsheb yuav kis tau. Ib qho hnyav 35-50kg, txaus rau cov neeg taug kev txhua hnub thiab cov tsheb me me.
Qib D400
Tau tshaj DN700-DN800 specifications, siv nyob rau hauv ob txoj kev thiab cov chaw lag luam, tuaj yeem ua raws li ntau hom tsheb pej xeem. Ib qho hnyav 50-70kg, zoo heev tiv taus crushing thiab qaug zog.
E600 qib
Tau tshaj DN800-DN900 specifications, siv nyob rau hauv txoj kev loj thiab Hoobkas cheeb tsam, tuaj yeem tiv taus forklift thiab nruab nrab cov tsheb thauj khoom. Ib qho hnyav 70-95kg, withstands 800,000 cycles ntawm alternating load tsis tawg.
IV. Siv tau Scenarios
DN600-DN700:
Feem ntau siv nyob rau hauv cov chaw nyob, cov kev taug kev, thiab txoj siv tawv ntsuab, rau cov cua daj cua dub, qis -voltage hluav taws xob qhov dej, thiab cov qhov dej me me, thaum tseem ua kom yooj yim txij nkawm thiab kev nyab xeeb rau cov neeg taug kev.
DN800-DN900:
Feem ntau siv nyob rau hauv lub nroog theem nrab thiab txoj kev loj, thaj chaw lag luam, thiab cov chaw tsim khoom siv dav dav, txuas cov dej nag thiab cov kav dej phwj hauv lub network nodes, tsim nyog rau cov dej ntws nruab nrab.
DN1000:
Siv nyob rau hauv hnyav- cov xwm txheej, xws li cov chaw pabcuam kev loj, chaw nres tsheb thauj khoom, chaw nres tsheb, thiab cov chaw ua haujlwm loj, tsim rau loj - txoj kab uas hla, yooj yim nkag mus rau cov neeg ua haujlwm thiab cov cuab yeej loj rau kev saib xyuas.
V. Qhov zoo thiab cov qauv
Qhov zoo: Tag nrho cov kev qhia tshwj xeeb, hloov tau rau qhov sib txawv loads thiab scenarios; los tiv thaiv- plam, tsis muaj dej, tiv thaiv- tub sab nyiag, thiab suab nrov- txo kev tsim, ntsuas kev nyab xeeb thiab ua tau zoo; hnav-tiv taus thiab corrosion- cov ntaub ntawv resistant, haum rau ib puag ncig ntawm -40℃mus rau 300 degree, tsis tshua muaj nqi txij nkawm.
Cov qauv: nruj me ntsis ua raws li GB/T 23858-2009 "National Standard for Manhole Npog" thiab cov kev cai hauv zos (xws li DB4401/T 215-2023); Cov khoom siv tiv thaiv tub sab nyiag, cov ntaub qhwv tsis tau, thiab lwm yam khoom ua tau raws li cov qauv khoom siv, kom ntseeg tau tias cov khoom ua raws.
