Round Recessed ductile iron access cover

Ductile hlau Recessed Npog thiab Ncej yog cov khoom siv hauv nroog pov tseg los ntawm cov hlau nplaum. Lawv cov yam ntxwv tseem ceeb yog cov vaj huam sib luag npog tuaj yeem muab tso rau hauv lub thav duab zawj, tso cai rau lub hau npog kom yaug nrog cov ntaub ntawv nyob ib puag ncig (xws li asphalt, pob zeb, thiab pob zeb). Cov khoom sib xyaw ua ke ntawm kev thauj khoom-cov kabmob kev tiv thaiv thiab kev ua haujlwm ntawm cov toj roob hauv pes, thiab yuav tsum tau tsim thiab tshuaj xyuas raws li cov qauv hauv lub tebchaws lossis kev lag luam (xws li Tuam Tshoj tus GB / T 23858, European Standard EN 124, American Standard ASTM A536).

Core ZoontawmDuctile hlau Recessed npog thiab ntas

Siab load-cov kabmob muaj peev xwm

Tom qab nodularization kev kho mob, ductile hlau muaj lub zog tensile ntau dua los yog sib npaug rau 420MPa thiab lub zog tawm los ntawm ntau dua los yog sib npaug rau 300MPa, uas tuaj yeem ua tau raws li ntau yam ntawm kev thauj khoom -cov kev cai ntawm A15 txog F900 hauv EN 124 tus qauv. Nws tsim nyog rau cov xwm txheej sib txawv xws li kev taug kev, txoj kev hauv nroog, thiab hnyav - txoj kab khiav haujlwm.

Kev sib koom ua ke toj roob hauv pes zoo heev

Kev tsim kho kom rov qab ua kom lub ntsej muag npog yuav tsum tau pav nrog cov ntaub ntawv tib yam li thaj chaw ib puag ncig, tshem tawm cov teeb meem protrusion los yog kev nyuaj siab ntawm cov tsoos manhole npog, tswj tag nrho cov kev zoo nkauj thiab kev tiaj tus ntawm txoj kev thiab cov squares, thiab txhim kho kev sib koom ua ke ntawm thaj chaw hauv nroog.

Zoo durability

Cov hlau hlau muaj qhov zoo tshaj plaws corrosion kuj thiab cuam tshuam tsis kam piv nrog cov hlau grey zoo tib yam. Nyob rau hauv ib puag ncig hnyav xws li kua qaub- hauv paus av, kub thiab txias heev, nws lub neej kev pab cuam muaj peev xwm tshaj 30 xyoo, thiab nws tsis yooj yim rau deformation, tawg thiab lwm yam txhaum.

Kev nyab xeeb siab

Cov qauv kev sib cuam tshuam ntawm tus ncej thiab lub hau npog tuaj yeem tiv thaiv lub hau ntawm kev hloov pauv thiab thaws, txo suab nrov thaum dov los ntawm tsheb; qee cov khoom tuaj yeem nruab nrog cov khoom siv tiv thaiv- tub sab tub nyiag kom tsis txhob muaj kev nyab xeeb los ntawm kev npog tub sab.

Kev saib xyuas yooj yim

Lub hau npog muaj txoj hauv kev qhib tau yooj yim, uas tuaj yeem qhib thiab kaw nrawm nrog cov cuab yeej tshwj xeeb, ua kom yooj yim rau kev tshuaj xyuas thiab kev saib xyuas cov kav dej hauv av (dej thiab tso dej, roj, kev sib txuas lus). Cov qauv yog ruaj khov thiab tsis yooj yim rau loosen vim nquag qhib thiab kaw.

FAQ

Q: 1.Dab tsi ua rau kev daws teeb meem lossis lub suab nrov txawv txav ntawm cov npog npog tom qab kev teeb tsa?

A: Muaj peb qhov laj thawj tseem ceeb: ①Uncompacted foundation pit lossis tsis txaus pob zeb ua rau lub hauv paus kev daws teeb meem; ② Qhov siab calibration yuam kev ntawm thav duab installation (ntau tshaj ± 2 hli), tsim qhov siab sib txawv nrog ib puag ncig pavement; ③ Ntau dhau qhov sib txawv ntawm lub hau thiab ncej, lossis kev laus / poob ntawm lub nplhaib sealing. Cov kev daws teeb meem suav nrog kev txhawb nqa lub hauv paus, recalibrating elevation, thiab hloov cov sealing qhov chaw.

Q: 2.Qhov kev pab cuam lub neej ntawm cov npog li no yog dab tsi, thiab yuav tsum tau ua haujlwm li cas?

A: Raws li tus qauv kev teeb tsa thiab ib puag ncig ib puag ncig, kev pabcuam lub neej ntawm cov ntaub npog npog tuaj yeem ncav cuag 30-50 xyoo; nyob rau hauv ntug dej hiav txwv siab -corrosion ib puag ncig, lub neej kev pab cuam tsis tsawg tshaj li 20 xyoo tom qab anti- kev kho corrosion xws li kub-dip galvanizing. Cov lus qhia txog kev saib xyuas niaj hnub: tshuaj xyuas cov khoom siv xauv / sealing txhua lub hlis twg, rov- ntsuas qhov siab thiab ruaj khov txhua xyoo, thiab ntsuas cov txheej txheem tiv thaiv corrosion txhua 3-5 xyoos.

Q: 3.Yuav ua li cas kom phim qhov tob tob ntawm cov ntaub npog npog nrog cov ntaub pua tsev nyob ib puag ncig?

A: Qhov tob tob yuav tsum tau ua raws li cov pavement thickness: ①50-60mm rau asphalt pavement; ②60-70mm rau pob zeb / cib pavement; ③50-80mm rau kev ua vaj tse. A 5-10mm npoo tuaj yeem khaws cia thaum lub sijhawm hloov kho kom huv si nrog txoj kev tom qab paving.

Q: 4.Cov khoom puas muaj kev tiv thaiv - tub sab nyiag thiab tiv thaiv - lub caij nplooj zeeg? Puas muaj feem cuam tshuam ntxiv?

A: Cov khoom lag luam txheem muaj cov qauv sib cuam tshuam los tiv thaiv kev txav mus los, thiab ob hom khoom siv ntxiv tuaj yeem ntxiv: ①Anti-cov khoom siv xauv xauv (cov tshuab xauv tshuab / ntse hluav taws xob ntsuas hluav taws xob) txhawm rau tiv thaiv kev nyiag khoom; ②Anti-poob nets/brackets (load-cov kabmob loj dua lossis sib npaug li 1000kg) kom tsis txhob muaj cov neeg ua haujlwm poob. Accessories tuaj yeem muab tso rau hauv cov khoom raws li xav tau.

Q: 5.Puas tsis yog - qhov ntau thiab tsawg lossis tshwj xeeb - cov npog npog tuaj yeem kho tau?

A: Customization yog txaus siab. Cov kev hloov kho tsis tu ncua muaj xws li: ①Circular inch 500-1200mm, square / rectangular side length 400-1000mm; ② Cov duab tshwj xeeb (elliptical / irregular) tuaj yeem tsim raws li cov duab kos, tab sis lub voj voog kev hloov kho yog 7-15 hnub ntev dua li cov qauv qauv, thiab kev hloov kho me me yuav raug nqi pwm.
