Cov cuab yeej siv cov khoom siv Manhole yog ib hom tshuaj xyuas manhole npog, thiab nws cov yam ntxwv tau piav qhia los ntawm cov khoom siv mathole, ntxiv cov khoom siv hluav taws xob, ntxiv cov khoom siv ntxiv, muab faus, thiab lwm yam.
Qhov tseeb, resin manhole npog (tseem hu ua polymer iav fiber ntau ntxiv rau cov khoom siv iav Nws muaj cov khoom lag luam tsis zoo, cov neeg sau ua ke, cov khoom lag luam tuab, cov yeeb yaj kiab qis dua, thiab tom qab ntawd yog cov khoom lag luam tshiab ntawm cov khoom siv kub.
Ntawm cov ntaub ntawv ntxiv, Fiber Reinfrced Khoom (iav ntaub, ntaub nplaum, thiab lwm yam.) Yog lub zog loj, lub zog loj thiab cov khoom siv tshwj xeeb. Piv txwv li, cov ntaub ntawv sib xyaw ntawm carbon fiber ntau thiab cov khoom siv kub, ua kom cov tawv nqaij tsis zoo, kev tawm tsam nws tus kheej, cov suab nrov txo thiab cov hluav taws xob. Qhov sib xyaw ua ke ntawm graphite fiber ntau thiab resin tuaj yeem tau txais cov khoom siv nrog kev nthuav dav coefficient yuav luag sib npaug rau xoom. Lwm qhov tshwj xeeb ntawm cov ntaub ntawv fiber ntau ntxiv yog anisotropy, yog li kev npaj ntawm cov fibers tuaj yeem tsim tau raws li cov khoom siv sib txawv ntawm cov khoom. Cov txheej txheem txhuas matrix ntxiv nrog cov roj carbon fiber thiab silicon carbide fibers thiab modulus ntawm 500 ° C.
Composite Manhole Npog tuaj yeem muab faib ua BMC thiab SMC raws li kev lag luam kev lag luam, cov txheej txheem ntau lawm thiab cov ntaub ntawv:
BMC (DMC) cov ntaub ntawv yog ntau cov pwm sib txuas. Nws feem ntau hu ua unsaturated polyester ntau molding compound hauv Suav teb. Cov khoom siv raw yog lub khob noom cookie uas zoo li sib xyaw ua ke los ntawm GF (tws iav fiber), nce (muab tub lim) thiab ntau yam ntxiv. DMC cov ntaub ntawv tau siv thawj zaug hauv cov hnub poob yav dhau los thiab Tebchaws Askiv, thiab tom qab ntawd Nyiv rau xyoo 1970 xyoo 1970, feem. Vim tias BMC ntau moulding muaj cov hluav taws xob hluav taws xob zoo, cov khoom siv hluav taws xob, thiab hloov kho cua sov, siv tshuab hluav taws xob, cov khoom siv hluav taws xob thiab lwm thaj chaw.
SMC Composites yog daim ntawv molding cov tebcing. Cov ntaub ntawv raw tseem yog tsim ntawm GF (cov xov paj tshwj xeeb), nce (unsaturated cob), qis shrinkage additive, MD (muab tub lim) thiab ntau tus neeg saib xyuas. Nws tau tshwm sim thawj zaug hauv Tebchaws Europe thaum xyoo 1960, thiab nyob ib ncig ntawm xyoo 1965, Tebchaws Asmeskas thiab Nyij Pooj kev ua tiav cov khoom siv tes ua no. Thaum xyoo 1980s, kuv lub teb chaws tau qhia tawm txawv teb chaws SMC ntau lawm kab thiab cov txheej txheem ntau lawm. SMC cov khoom siv thiab lawv cov khoom siv smc folded muaj hluav taws xob hluav taws xob, cov cuab yeej siv tshuab cua sov, thiab tshuaj lom neeg tiv taus. Yog li, daim ntawv thov ntau ntawm SMC cov khoom lag luam yog qhov muaj ntau. Qhov kev txhim kho kev loj hlob tam sim no yog los hloov cov ntaub ntawv BMC nrog smc composites.
Tam sim no daim ntawv thov ntawm peb lub resin manhole cov npe tau ua lub luag haujlwm zoo hauv peb lub neej, thiab cov resin manhole npog sawv tawm vim tias lawv txoj haujlwm tu lawv tus kheej.
Kev siv ntawm resin manhole npog ntawm txoj kev muaj cov yam ntxwv ntawm rwb thaiv tsev, tsis muaj suab nrov, tsis muaj nqi zog thiab kev tiv thaiv kev ua tub sab. Nws yog irreplacable rau cam khwb cia hlau manhole npog.
Lub resin manhole npog yog tsim los ntawm ib tug tshwj xeeb molding txheej txheem, uas ua rau lub nroog saib tshiab. Qhov kev pabcuam lub neej yog qhov tseem ceeb 20-50 xyoo. Lub Resin Composite Manhole npog tsim los ntawm cov kub molding muaj qhov zoo ntawm lub teeb ceeb thiab siab muaj zog, kev nyab xeeb zoo heev thiab kev puas tsuaj loj. Nws muaj qhov zoo ntawm cov suab sib xyaw yooj yim, cov tshuaj sib tsoo tsis tshua muaj, zoo nkauj acid thiab alkalans, thiab cov pa phem nyob rau hauv cov dej ntas yog txo ntxiv.
Tam sim no ntawm kev ua lag luam tsim tawm los ntawm ntau yam Manhole Npog tuam ntxhab yog ua ntawm cov khoom sib txawv, tab sis ob peb nta zoo sib xws:
1. Lub zog tiv thaiv tub sabqab: Composite Npog yog feem ntau ua los ntawm cov txheej txheem tsis muaj zog, thiab cov khoom tsis muaj nqi dua. Kev txhawb nqa tsis yooj yim heev.
2. Kev Pab Lub Neej: Los ntawm kev siv cov txheej txheem ua haujlwm siab, cov khoom siv tshwj xeeb thiab cov khoom siv tshwj xeeb tau ua kom zoo, yog li cov khoom siv yuav tsis raug puas raws li kev coj ua. Sab hauv kev puas tsuaj tshwm sim, yog li ua kom muaj kev pabcuam lub neej ntawm cov khoom lag luam resin composite manhole npog, zoo tshem tawm qhov tsis zoo ntawm cov nplaum tsis zoo.
3. Kev kub siab / qis kub tsis kam, zoo rwb thaiv tsev ua haujlwm thiab muaj zog corrosion-resistant, tsis-toxic thiab tsis muaj mob. Tsis muaj hlau ntxiv. Nws tuaj yeem siv rau hauv cov nyom thiab hloov pauv tau, hnyav thiab xav tau chaw. Lub manhole npog tsim los ntawm cov khoom lag luam manhole zoo tshaj plaws, thiab muaj cov txheej txheem ua kom pom tseeb, tiv thaiv kev laus thiab ntau lwm qhov ntsuas tau raws li cov khoom lag luam zoo.
4. Zoo nkauj thiab cov tswv yim, qib siab: Raws li cov kev xav tau ntawm cov neeg siv khoom siab, peb tuaj yeem ua ntau yam xim ntawm tib lub manhole. Raws li cov neeg siv khoom, nws tuaj yeem ua rau ntau qhov qog pob zeb pom thiab cov xim uas yog tib yam li ntau yam pob zeb.
5. Cov kabmob muaj zog muaj peev xwm: cov hauv qab adopts cov qauv tsim tshwj xeeb, thiab cov ntaub qhwv ua ke kom ntseeg tau, kom cov khoom muaj peev xwm coj muaj peev xwm.
6. Kev tiv thaiv ib puag ncig, tsis muaj suab paj nruag: lub manhole npog yuav tsis plam tom qab lub tsheb yog dov, thiab yuav muaj tsis muaj suab nrov nrov thiab muaj kuab paug.
Thaum txhim kho lub tshuab manhole, ua raws li cov plaub kauj ruam no:
1. Ua ntej kev teeb tsa, lub hauv paus ntawm Manhole cover yuav tsum tau huv thiab khov kho, ntev thiab dav yuav tsum txiav txim siab raws li qhov loj me ntawm manhole npog.
2. Thaum txhim kho cov tshuaj manhole manhole npog ntawm txoj kev xis mas yuav tsum tau muab nchuav nrog cov pob zeb ua kom zoo, thiab lub pob zeb ua kom zoo rau kev saib xyuas li 10 hnub.
3. Thaum txhim kho Composite Manhole npog, kev saib xyuas kom tsis txhob siv cov tshuab siv nyiaj ncaj qha rau lub manhole npog thiab lub rooj zaum kom tsis txhob muaj kev puas tsuaj.
4. Txhawm rau tswj cov manhole ntawm manhole npog thiab cov qauv, yuav tsum ceev faj kom tsis txhob ua kom zoo li asphalt thiab xis mas ntawm txoj kev nto.
Txoj kev loj hlob:
(1) Nws lub zog yog thib ob rau ntawm pob zeb yas manhole npog. Nws tuaj yeem nqa ntau tshaj li 40 tons ntawm cov tsheb.
(2) Nws txoj kev ua tau zoo tshaj plaws yog nruab nrab ntawm lub pob zeb-yas manhole npog thiab cov pob zeb ua vaj tse manhole npog, uas yog qhov zoo dua li ntawm cov pob zeb ua ke; Nws tuaj yeem siv nyob rau hauv cov sij hawm nrog cov kev xav tau siab rau lub duav manhole.
(3) Nws cov txiaj ntsig zoo tshaj plaws yog tias nws tsis siv cov hlau pob txha pob txha pob txha pob txha pob txha, tab sis yog cov khoom grc fiber ntau, uas zwm rau cov khoom grc. Yog li ntawd, nws muaj qhov zoo ntawm kev cuam tshuam thaum tus nqi ntawm cov hlau txuas ntxiv mus. Vim tias nws tsis muaj cov hlau me me, nws yog kev tiv thaiv me me dua pob zeb yas thiab fiber ntau pob zeb.
(4) Nws txoj kev kho tau ceev yog ntau zaus sai dua li ntawm Fiber ntau cov qhob, thiab nws tuaj yeem muaj txiaj ntsig hauv 8 teev. Yog tias nws tau tsim nyob rau hauv peb lub sijhawm, nws tuaj yeem hais tau peb zaug hauv 24 teev. Txawm hais tias tus nqi ntawm pwm yog ntau tshaj li ntawm lub pob zeb yas, nws tsuas yog 1/6 ntawm cov khoom siv fiber ntau. Nws kuj tseem tuaj yeem txo cov roj peev pwm. Nrog rau txhua xyoo cov zis txhua xyoo ntawm 10,000 teeb ntawm Manhole npog, tsuas yog 10 lub teeb pwm.
(5) Lub Composite Manhole Npog yog qhov zoo tshaj plaws, thiab ua tau zoo dua nrog roj hmab tuaj pwm (xws li roj hmab tuaj pwm, iav fiber ntau ntxiv dag pwm).
(6) Hauv kev txhim kho txuas ntxiv thiab hloov kho ntawm Manhole cov khoom siv, ntau yam ntsuas tau tshaj qhov kev ua haujlwm ntawm kuv lub teb chaws Manhole cov khoom lag luam.
