Rectangle Ductile Iron Manhole Npog yog ib qho khoom siv txhawb nqa rau cov kav dej hauv av hauv thaj chaw hauv nroog. Nws yog tsuas yog siv los npog cov duab plaub hauv av tshuaj xyuas qhov dej hauv thaj chaw xws li txoj kev, kev taug kev, thiab txoj siv sia ntsuab. Nws tuaj yeem tiv thaiv cov kav dej hauv av xws li dej thiab dej ntws, roj, hluav taws xob, thiab kev sib txuas lus, thiab muaj lub luag haujlwm tseem ceeb ntawm kev tiv thaiv kev nyab xeeb thiab kev ua haujlwm yooj yim thiab kev saib xyuas, ua ib qho kev tiv thaiv tseem ceeb ntawm lub nroog underground yeeb nkab network system.

Nyob rau hauv cov nqe lus ntawm cov yam ntxwv ntawm cov khoom, Rectangle Ductile Iron Manhole Npog muaj cov hauv qab no cov txiaj ntsig zoo nyob ntawm kev ua tau zoo ntawm cov khoom siv hlau thiab cov duab plaub:

Muaj zog adaptability

It can accurately match the size of rectangular inspection well openings and can be flexibly arranged in narrow or special-shaped installation areas, especially suitable for municipal road sections with dense pipelines and wellhead shapes limited by surrounding facilities.

Zoo heev load-cov kabmob muaj peev xwm

Cov khoom siv hlau ductile yog smelted thiab cua sov- kho nrog cov qauv ntawm cov qib xws li QT500-7, nrog lub zog tensile ntawm Ntau dua lossis sib npaug rau 500MPa thiab lub zog tawm los ntawm Ntau dua lossis sib npaug rau 300MPa. Nws tuaj yeem ua tau raws li qhov kev thauj khoom-cov kev cai ntawm cov qib sib txawv ntawm A15 txog D400 hauv EN124 tus qauv, haum rau ntau yam xwm txheej xws li kev taug kev, txoj kev loj, thiab txoj kab tsheb hnyav.

Anti- tub sab nyiag thiab ruaj khov

Nws tuaj yeem nruab nrog kev tiv thaiv - khawm hinges thiab tiv thaiv - tub sab tub nyiag cov txheej txheem los tiv thaiv lub hau npog ntawm kev hloov lossis raug nyiag; nws cov kev tiv thaiv corrosion thiab cuam tshuam tsis zoo yog qhov zoo tshaj rau cov hlau cam khwb cia zoo tib yam, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 30 xyoo nyob rau hauv ib txwm ua haujlwm.

Zoo sealing kev ua tau zoo

Cov roj hmab gasket tuaj yeem ntsia nruab nrab ntawm lub hau npog thiab lub qhov dej, uas tuaj yeem tiv thaiv cov dej nag, cov khib nyiab thiab cov khib nyiab los ntawm kev nkag mus rau hauv qhov dej thiab ua kom muaj kev ruaj ntseg ntawm cov kav dej.

Cov qauv tsim sib txawv ntawm Rectangle Ductile Iron Manhole Npog thiab cov tsoos voj voog manhole npog yog qhov tseem ceeb hauv kev hloov kho ntawm cov qauv qauv thiab daim ntawv thov scenarios: Nyob rau hauv cov nqe lus ntawm cov qauv kev ruaj ntseg, ncig manhole npog tuaj yeem ua tiav kev sib faib quab yuam vim lawv cov yam ntxwv geometric thiab yuav tsis poob rau hauv qhov dej xav tau vim yog flipping, thaum lub kaum sab xis ntawm lub kaum sab xis ntawm kev ntxhov siab. tav thiab yuav nruab nrog cov khoom siv tiv thaiv- ntog los ua rau qhov tsis zoo ntawm nws cov duab; Hais txog cov xwm txheej ntawm daim ntawv thov, lub voj voog manhole npog yog qhov tsim nyog rau qhov loj - txoj kab uas hla kev soj ntsuam lub qhov dej, thaum Rectangle Ductile Iron Manhole Npog yog qhov tsim nyog rau cov dej tshuaj ntsuam xyuas qhov sib npaug nrog ntau qhov sib npaug - cov kav dej, uas tuaj yeem npog ntau qhov chaw nyob ib puag ncig tib lub sijhawm thiab txhim kho qhov chaw siv; Nyob rau hauv cov nqe lus ntawm kev yooj yim installation, ncig manhole npog tuaj yeem ntsia tau rau hauv kev sib dhos ntawm txhua lub kaum sab xis, thaum Rectangle Ductile Iron Manhole Npog yuav tsum tau npaj kom raug raws li cov kev taw qhia, tab sis nws cov duab plaub tuaj yeem ua tau zoo dua rau txoj kev pavement thiab txo qhov kev puas tsuaj rau txoj kev flatness.

Nrog nws cov qauv duab plaub tshwj xeeb thiab cov khoom siv zoo ntawm cov hlau nplaum, Rectangle Ductile Iron Manhole Npog tau dhau los ua cov khoom lag luam nyiam rau kev tiv thaiv tshwj xeeb - zoo li lub taub hau zoo hauv kev tsim vaj tsev hauv nroog, muab kev lees paub zoo rau kev ua haujlwm nyab xeeb thiab kev saib xyuas cov kav dej hauv nroog hauv nroog.

FAQ

Q: 1.Vim li cas ductile hlau raug xaiv los ua cov khoom siv rau Rectangle Ductile Iron Manhole Npog es tsis txhob siv cov cam khwb cia zoo tib yam?

A: Cov hlau hlau muaj cov qauv graphite, uas ua rau nws lub zog tensile (Ntau dua lossis sib npaug rau 420MPa) 2-3 npaug ntawm cov hlau grey zoo tib yam, thiab elongation (Ntau dua lossis sib npaug li 7%) deb siab dua li ntawm cov hlau tsis xeb hlau. Nws tuaj yeem tiv taus qhov cuam tshuam thiab deformation nyob rau hauv cov khoom hnyav, thiab nws lub neej kev pabcuam yog tshaj 30 xyoo (ob zaug ntawm cov hlau cam khwb cia). Rau Rectangle Ductile Iron Manhole Npog, uas yuav tsum tau dais qhov kev ntxhov siab tsis sib xws ntawm cov ces kaum, cov hlau tsis muaj zog tuaj yeem ua kom tsis txhob tawg.

Q: 2.Will Rectangle Ductile Iron Manhole Cover poob rau hauv qhov dej yooj yim? Yuav tiv thaiv li cas?

A: Tsis zoo li lub voj voog manhole npog (uas yuav tsis poob vim lub cheeb tsis sib xws), cov duab plaub muaj qhov ntev thiab dav tsis sib npaug, yog li lawv yuav poob yog tias flipped. Txhawm rau daws qhov no, Rectangle Ductile Iron Manhole Npog yog nruab nrog cov khoom siv tiv thaiv- ntog: ① Anti- poob nets (load-cov kabmob loj dua lossis sib npaug li 100kg) kho ntawm lub qhov ncauj qhov dej; ② Ua-hauv kev tiv thaiv- ntog hooks ntawm lub hau, uas khi lub qhov dej thaum lub hau qhib. Cov qauv tsim no tshem tawm tag nrho cov kev pheej hmoo ntawm kev poob.

Q: 3.Puas Rectangle Ductile Iron Manhole Npog puas muaj kev taw qhia thaum lub sijhawm teeb tsa?

A: Yog. Cov qauv duab plaub txiav txim siab tias nws tsis tuaj yeem ntsia tau ntawm yuav zoo li lub voj voog. Lub sab ntev ntawm lub hau yuav tsum ua raws li qhov ntev ntawm lub rooj zaum zoo: ① Txhawm rau kom cov ribs txhawb nqa (tseem raws li qhov kev ntxhov siab) dais kom raug; ② Ua kom cov roj hmab foob ntawm lub hau npog thiab lub rooj zaum zoo kom nruj (tsis txhob muaj dej los nag); ③ Ua kom haum rau txoj kev pavement, txo qhov kev pheej hmoo ntawm kev sib tsoo tsheb. Misalignment yuav txo cov load-cov kabmob muaj peev xwm los ntawm 30% thiab ua rau muaj qhov tshwm sim tuaj yeem.

Q: 4.Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov hlau nplaum thiab cov khoom sib xyaw manhole npog?

A: Cov hlau tsis muaj zog: siab zog (500MPa vs 100-200MPa composite), lub neej ntev (30-50y vs 15-20y), 100% rov ua dua, qis dua lub neej voj voog.

Q: 5. Koj puas tuaj yeem tsim cov khoom raws li kuv tus kheej kos duab?

A: Yog, peb tuaj yeem ua tau. SND FOUNDRY yog kev tshaj lij thiab kev nplua nuj ntawm manhole npog.
Peb muaj peb tus kheej tsim pab pawg, chav kuaj, cov kab ntau lawm tsis siv neeg, cov tshuab tua tub ntxhais, cov txheej txheem ua npuas ncauj, kev sib tsoo & ntxuav rhiav, sib dhos rhiav, thiab tag nrho cov txheej txheem tshuaj xyuas.
