Kev tsim kho ntawm cov yeeb nkab yas

(1) Cov txheej txheem ntawm cov kav dej tso tawm muaj qhov cuam tshuam zoo rau kev tsim cov dej ntws ntawm qhov system.Lub luj tshib yuav tsum tau siv rau kev sib txuas ntawm cov riser thiab cov yeeb nkab tawm.Lub qhov hluav taws xob yeeb nkab yuav tsum zoo dua yog ib qhov loj dua li cov riser.Lub qhov hluav taws xob cov yeeb nkab yuav tsum tso cov dej phwj tawm sab nraud kom zoo li qhov ua tau yam tsis muaj lub luj tshib lossis b-pipe hauv nruab nrab.Ntau qhov dej num tau lees paub tias cov yeeb nkab ua kom zoo dua thiab cov yeeb nkab txuas ntxiv ntawm cov yeeb nkab hluav taws xob yuav cuam tshuam qhov kev faib tawm ntawm cov yeeb nkab, txo cov nqi tso cai, thiab nws yog ib qho yooj yim uas yuav ua rau cov dej tsis zoo ntawm cov chav dej hauv cov txheej txheem. tom qab siv.

(2) UPVC kauv yeeb nkab tso kua dej kom ntseeg tau tias cov kauv poob ntawm kauv yeeb nkab dej ntws thiab txo cov suab nrov, cov riser tsis tuaj yeem txuas nrog lwm cov risers, yog li yuav tsum tau txais ib qho kev ywj pheej ib leeg riser, uas kuj yog ib qho ntawm Cov yam ntxwv ntawm UPVC kauv yeeb nkab.Zam los ntawm tag nrho cov txhais tau tias ntxiv cov ntsiab lus superfluous, luam cov kav dej ntawm cov kav hlau cam, thiab ntxiv cov kav dej tso rau hauv cov tsev siab.Yog tias cov kav dej tso tawm ntxiv, nws yuav tsis tsuas yog cov khoom pov tseg xwb, tab sis kuj tseem rhuav tshem cov yam ntxwv ntawm cov kav dej kauv.

(3) Qhov tshwj xeeb tee los yog plaub-txoj kev yeeb nkab fittings rau sab dej inlet siv ua ke nrog cov kauv yeeb nkab muaj rau cov txiv ntseej extrusion roj hmab nplhaib sealing zawv zawg sib koom ua ke.Feem ntau, qhov tso cai nthuav dav thiab zawv zawg qhov deb yog nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias hauv cov qauv siv thiab siv theem.Raws li UPVC pipeline expansion system, qhov tso cai ntev ntawm cov yeeb nkab yog 4m, uas yog hais tias nws yog ib tug riser los yog kab rov tav ceg yeeb nkab, ntev li ntev raws li cov yeeb nkab seem nyob rau hauv 4m, tsis txhob teem lwm expansion sib koom ua ke.

(4) Kev sib txuas ntawm cov kav dej.UPVC kauv yeeb nkab txais cov txiv ntseej extrusion roj hmab nplhaib sealing sib koom ua ke.Hom kev sib koom tes no yog ib hom zawv zawg sib koom ua ke, uas tuaj yeem ua lub luag haujlwm ntawm kev nthuav dav thiab kev cog lus.Yog li ntawd, qhov tsim nyog tshwj xeeb qhov sib txawv tom qab tso cov yeeb nkab yuav tsum tau txiav txim siab raws li cov cai.Tsis txhob hnov ​​​​qab tias qhov sib txawv tshwj xeeb loj dhau los yog me me vim qhov yooj yim ntawm tus neeg ua haujlwm thaum lub sijhawm tsim kho, thiab cov raj xa dej deformation yuav ua rau cov dej xau nrog kev hloov pauv ntawm lub caij ntuj sov yav tom ntej.Txoj kev tiv thaiv yog txhawm rau txiav txim siab qhov sib txawv tshwj xeeb raws li kev tsim kho kub ntawm lub sijhawm ntawd.Thaum lub sij hawm tsim kho ntawm txhua qhov sib koom ua ke, cov cim ntxig yuav tsum ua rau ntawm cov yeeb nkab ntxig ua ntej, thiab cov cim ntxig tuaj yeem ncav cuag lub sijhawm ua haujlwm.

(5) Hauv kev tsim ntawm qee lub tsev siab siab, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam cov kavThaum lub sij hawm tsim kho, sab nrauv phab ntsa ntawm cov yeeb nkab yas ntxig rau hauv lub qhov (socket) ntawm cov yeeb nkab hlau cam khwb cia yuav tsum tau roughened kom muaj kev sib txhuam thiab ceev ceev nrog cov caulking muab tub lim.

(6) Vim muaj qhov sib txawv ntawm qhov sib txawv ntawm sab hauv thiab sab nraum zoov thiab cua daj cua dub, kev tawg tawg feem ntau tshwm sim ntawm qhov sib txuas ntawm lub qhov cua yeeb nkab ncig thiab lub ru tsev waterproof txheej los yog thermal rwb thaiv tsev txheej, ua rau lub ru tsev to.Txoj kev tiv thaiv yog ua kom lub nplhaib thaiv dej 150mm-200mm siab tshaj li txheej saum toj kawg nkaus nyob ib ncig ntawm lub ru tsev qhov cua yeeb nkab.

(7) Muaj ob qhov teeb meem tshwm sim hauv kev tsim kho cov yeeb nkab faus: ib qho yog tias cov kav dej tso rau hauv qab hauv pem teb tsis tau nqa tawm tom qab cov khoom siv rov qab tau ntim.Tom qab cov khoom siv rov qab yog compacted, txawm hais tias qhov kev ntsuas dej ntim tau tsim nyog ua ntej compaction, cov kav dej sib txuas yog tawg, deformed thiab xau tom qab siv: lwm qhov yog tias sab laug, sab xis thiab sab sauv ntawm cov kav dej zais tsis npog nrog xuab zeb, ua rau nyob rau hauv cov khoom ntse ntse los yog pob zeb ncaj qha kov lub phab ntsa ntawm cov yeeb nkab, uas ua rau muaj kev puas tsuaj, deformation los yog to ntawm cov yeeb nkab phab ntsa.

(8) Kev teeb tsa ntawm sab hauv tsev UPVC kauv yeeb nkab yuav tsum tau nqa tawm tsis tu ncua tom qab ua tiav ntawm kev kos duab phab ntsa.Qhov tseeb, vim yog lub sijhawm tsim kho, feem ntau ntawm lawv tau ua tiav ib txhij nrog kev kho kom zoo nkauj tom qab ua tiav cov qauv tseem ceeb.Qhov no yuav ua rau lub ntsej muag du thiab zoo nkauj kom muaj kuab paug.Qhov kev daws teeb meem zoo tshaj plaws yog qhwv nws nrog cov ntaub yas hauv lub sijhawm nrog kev teeb tsa ntawm UPVC kauv yeeb nkab thiab tshem tawm tom qab ua tiav.Tsis tas li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau cov khoom tiav kev tiv thaiv ntawm UPVC kauv kav dej thaum siv.Nws yog nruj me ntsis txwv tsis pub nce rau ntawm lub raj xa dej, khi txoj hlua ruaj ntseg, txhim kho lub rooj tsav xwm scaffold, siv nws los txhawb lossis qiv rau lwm yam.

Qhov siab tshaj plaws ntawm cov dej hauv pem teb yuav tsum yog 5 ~ 10mm qis dua hauv av, thiab cov dej foob qhov tob ntawm cov dej hauv pem teb yuav tsum tsis pub tsawg tshaj 50mm Lub hom phiaj yog los tiv thaiv cov pa phem hauv cov kav dej phwj tuaj nkag hauv chav thiab ua paug. kev huv huv hauv tsev tom qab cov dej foob puas lawm.Txawm li cas los xij, nws tsis tshua muaj hais nyob rau hauv cov lus piav qhia ntawm cov khoom siv dej thiab cov qauv tsim kom txo tau tus nqi, chav tsev tsim kho thiab kev tsim kho siv cov dej hauv pem teb nrog tus nqi qis hauv kev ua lag luam.Cov dej foob hauv pem teb no feem ntau tsis pub ntau tshaj 3cm, uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm cov dej foob qhov tob.Tsis tas li ntawd, thaum cov neeg nyob hauv kho kom zoo nkauj lawv lub tsev, lawv xaiv cov hlau tsis huv hauv pem teb ntws hauv khw kho kom zoo nkauj los hloov cov yas hauv pem teb qub.Txawm hais tias qhov zoo li ci ntsa iab thiab zoo nkauj, lub foob dej sab hauv kuj tseem ntiav heev.Thaum cov dej ntws tawm, cov dej foob ntawm cov dej hauv pem teb raug puas vim qhov zoo siab (hauv pem teb hauv qab) lossis tsis zoo siab (siab dua hauv pem teb), thiab cov ntxhiab nkag mus rau hauv chav.Ntau tus neeg nyob hauv tsev tau tshaj tawm tias muaj ntxhiab tsw phem hauv tsev, thiab chav ua noj chav ua noj hood yog qhov hnyav dua thaum nws qhib, uas yog vim li cas cov dej foob tau puas vim qhov hloov pauv siab.Qee cov chav ua noj hauv tsev yog nruab nrog cov dej hauv pem teb.Vim tias tsis muaj dej ntxiv rau lub sijhawm ntev, tshwj xeeb tshaj yog nyob rau lub caij ntuj no, cov dej foob tau yooj yim kom qhuav, yog li cov dej hauv pem teb yuav tsum tau muab ntxiv ntau zaus.Nws raug nquahu kom txais yuav cov dej siab siab lossis cov dej ntws tawm tshiab hauv pem teb thaum tsim thiab tsim kho.Muaj tsawg dua dej txaws rau sab hauv ntawm chav ua noj, yog li cov dej hauv pem teb tsis tuaj yeem teeb tsa.
