Cov kav dej phwj dej, qhov ntau thiab tsawg uas tau nthuav tawm hauv qab no, tau dhau los ua neeg nyiam tshaj plaws. Lawv yog tsim los ntawm polypropylene, polyvinyl chloride, polybutylene, thiab polyethylene. Cov khoom zoo li no nyob rau hauv kev thov nyob rau hauv kev npaj ntawm cov kav dej phwj tuaj, uas yog yus muaj los ntawm tsis kam mus rau txhoj puab heev tshuaj. Cov kav dej tuaj yeem muab tso rau hauv cov av hauv tsev lossis kev lag luam. Cov khoom lag luam zoo muaj qhov zoo meej smoothness, uas tshem tawm qhov muaj peev xwm ntawm clogging. Thaum lub sij hawm installation, koj yuav tau siv ib txwm hacksaw tsim rau hlau, cov hniav uas yuav tsis tsim burrs.
Kev piav qhia ntawm cov kav dej yas
Cov kav dej yas rau cov kav dej phwj tuaj, qhov ntev ntawm cov qauv yuav tau piav qhia hauv qab no, yog ua los ntawmpolymer compounds. Cov cuab yeej technology guarantees durability, kev cia siab thiab durability ntawm cov kav dej phwj system. Koj tuaj yeem siv cov khoom siv sab hauv thiab sab nraum lub tsev. Lub peev xwm ntws tseem unsurpassed txawm tias cov yeeb nkab yog khoov rau lub kaum sab xis xav tau. Thaum txhim kho cov kav dej phwj tuaj, koj tuaj yeem suav cov nqi tsim nyog, ua haujlwm ntev, thiab qhov tsis xav tau kev tiv thaiv cathodic. Yog li, tom qab ua haujlwm tiav, tsis tas yuav tsum muaj kev saib xyuas tas li. Cov kav dej muaj cov yam ntxwv ntawm cov thermal conductivity tsawg, uas tiv thaiv cov dej los ntawm khov. Qhov hnyav ntawm cov khoom tso cai rau lawv tuaj yeem txuas nrog yam tsis muaj kev koom tes ntawm cov cuab yeej tshwj xeeb, thiab kev tiv thaiv kev ruaj ntseg tiv thaiv kev kis tus kab mob thiab kab mob.
Sizes
Cov kav dej yas yas, qhov zoo ntawm cov uas tau piav qhia saum toj no, tuaj yeem muaj qhov sib txawv, txhua tus yog tsim los rau qhov sib txawv ntawm qhov load. Yog tias xav tau kev tsim cov kav dej phwj tuaj rau lub tsev tsev lossis chaw sib raug zoo, yuav tsum siv txoj kab uas hla zoo dua. Yog li, qhov taw qhia hais txog 200 millimeters yog tsim rau tsev kho mob, tsev so lossis sauna. Ib txoj kab uas hla zoo sib npaug rau 300 millimeters yog siv rau hauv kev ua haujlwm ntawm cov chaw tsim khoom. Hom thiab qhov ntau thiab tsawg ntawm cov kav dej yas rau cov kav dej yuav tsum tau xaiv ua ntej pib ua haujlwm. Hauv kev tsim kho tus kheej, cov kav dej ntawm ib txoj kab uas hla me me yog siv. Yog li, yog tias siv thaum txhim kho riser 150millimeters, ces nws yuav tsis siv tag nrho, uas yog qhov tseeb rau ib lub tsev uas muaj ntau chav dej txwv rau plaub.
Standards for sewer plastic pipes
Raws li cov kav dej nomenclature yog ua los ntawm cov yas, txoj kab uas hla tuaj yeem sib npaug li 50-110 millimeters. Nyob rau hauv cov ntaub ntawv no, lub thickness nws txawv ntawm 3 mus rau 3.2 millimeters. Rau kev npaj cov dej phwj tuaj sab nraud, yuav tsum siv ntau yam thib ob, uas muaj peev xwm muab cov khoom siv dag zog uas xav tau. Yog tias koj xav tau cov kav dej yas, nws yog ib qho tseem ceeb kom paub xaiv qhov ntau thiab tsawg ua ntej kev yuav khoom. Txawm li cas los xij, nws yog ib qho tseem ceeb rau kev txiav txim siab yam khoom koj xav tau. Piv txwv li, cov pob qij txha sab nraud, nrog rau kev lag luam, yuav tsum tau siv cov kav dej corrugated ua los ntawm ob txheej polyethylene. Ntawm cov txiaj ntsig tseem ceeb hauv qhov no yog cov tshuaj tiv thaiv, lub nplhaib zoo heev, uas tso cai rau tso rau hauv qhov tob txog li 20 meters. Rau kev npaj ntawm lub tshuab siab, cov kav dej polyethylene yog siv, uas muaj cov khoom tsim nyog. Txoj kab uas hla yuav txawv ntawm 10 mus rau 1200 millimeters.
Siv IPA
Qhov ntev ntawm cov kav dej yas tau hais los saum toj no, tab sis nws tseem ceeb heev rau kev txiav txim siab ntawm cov khoom lag luam. Ntawm lwm tus, nws yuav tsum tau muab sau tseg tias tsis tshua muaj siab polyethylene, uas yog tus yam ntxwv ntawm siabzog. Nws muaj kev tiv thaiv zoo heev rau qhov chaw nruj heev.
GOST 22689.2-89
Nws yog ib qho tseem ceeb uas yuav tsum xaiv qhov loj ntawm cov kav dej yas rau cov kav dej, nrog rau kev txiav txim siab ntawm ntau yam. Cov khoom lag luam corrugated saum toj no tsis raug tswj hwm los ntawm lub xeev cov qauv thiab tuaj yeem tsim nyob rau hauv cov xwm txheej uas tau pom zoo ua ntej nrog tus neeg siv khoom. Raws li cov kav dej polyethylene rau kev sib txuas lus sab hauv, GOST tau hais los saum toj no yog siv hauv kev tsim khoom. Nws hais tias cov yeeb nkab tuaj yeem muaj qhov loj ntawm 2 mus rau 8 meters. Cov nram qab no tsis ua raws li qhov nruab nrab qhov tseem ceeb 3; 5, 5; 6. Rau kev ua haujlwm sab hauv, txoj kab uas hla ntawm cov yeeb nkab no tuaj yeem yog 40 txog 110 millimeters. Cov nqi nruab nrab yog 50 thiab 90 millimeters.
txwv tsis pub siv
Nws yog ib qho tseem ceeb uas yuav tsum xaiv qhov loj ntawm cov kav dej yas rau cov kav dej phwj tuaj, tab sis koj yuav tsum coj mus rau hauv tus account qee qhov kev txwv ntawm daim ntawv thov. Tus qauv xav tias siv cov kav dej los npaj lub ntiajteb txawj nqus hauv cov kav dej. Raws li rau cov tshuab siab, lawv tau muab tso rau hauv raws li lwm cov ntaub ntawv tswj hwm. Txawm hais tias tus qauv, cov yeeb nkab polyethylene, uas yog nruab nrog cov roj hmab foob, tuaj yeem ua ib feem ntawm lub kaw lus siv cov twj tso kua dej. Yog hais tias lub siab yog negligible, qhov kev twb kev txuas no yuav txaus nyob rau hauv ntau. Hom thiab qhov ntau thiab tsawg ntawm cov kav dej yas yuav tso cai rau kojequip lub system kom raug, tab sis nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account qee cov ntsiab lus uas yuav tsum tau saib xyuas thaum ua haujlwm. Yog li, cov khoom tsim los rau qhov kub thiab txias tsis tshaj 45 degrees. Txawm li cas los xij, kev nce lub sij hawm luv luv uas tuaj yeem ncav cuag 60 degrees tau txais.
Qhov kev xav tau no tau pom zoo kom ua tib zoo, zam kev siv cov dej kub kub tawm.
Recommendations
Cov kav dej yas, muaj ntau qhov ntau thiab tsawg, yog siv los tsim cov kab ke hauv nroog thiab nyob deb nroog. Cov kav dej zoo li no tau siv ntau thiab ntau zaus vim tias lawv tsis ntshai ntawm cov av txav thiab txawv ntawm plasticity thiab yooj. Cov kav dej yas yas, qhov ntev ntawm qhov koj yuav tsum xaiv ua ntej pib ua haujlwm, tsis muaj hluav taws xob, muaj kev tiv thaiv corrosion zoo thiab tsis ntshai ntawm kev nruj heev. Koj tsis tuaj yeem ntshai tias ya raws thiab dampness yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Ntawm lwm yam, qhov saum npoo tsis yog ib puag ncig zoo rau kev tshwm sim thiab kev loj hlob ntawm cov kab mob.
Ntxiv nta
Siv cov khoom piav qhia, koj tuaj yeem suav nrog lub neej ntev, uas tau lees paub rau 50 xyoo. Yog tias qhov kev tso tawm tau ua kom raug, thiab kev ua haujlwm tau ua raws li cov cai, lub sijhawm no yuav raug ncua. Cov neeg siv khoom kuj xaiv cov khoom no vim tias lawv tuaj yeem nqus cov suab nrov, uas yog qhov zoo dua lwm cov kav dej yas.
Zaj lus
Yog tias nyob rau hauv cov txheej txheem ntawm kev ua hauj lwm koj yuav siv corrugated kav, ces zawv zawg couplings yog siv los koom lawv. Lawv raug xaiv yog tias tsim nyog los nteg cov txheej txheem hauv cov av sab nraum qhov chaw. Thaum npaj cov kev sib txuas sab hauv, qhov uas nws yog kev cai siv cov kav dej nrog cov qhov (socket), kev ua haujlwm yuav tsum tau ua los ntawm kev siv tib lub thev naus laus zis uas tau siv thaum siv lwm cov yeeb nkab yas nruab nrog sealing rubber rings. Thaum ua haujlwm, ib qho tseem ceeb tshaj plaws yog qhov yuav tsum tau siv cov khoom zoo.
