Lub Trench
Lub teb chaws thiab cheeb tsam cov cai thiab cov lus qhia rau cov av npogPE pipelinesyuav tsum tau ua raws li thaum lub sij hawm tsim kho ntawm qhov tsim nyog trench. Lub trench yuav tsum tso cai rau txhua qhov chaw ntawm lub raj xa dej kom nyob rau hauv qhov tob tob thiab qhov dav txaus.
Trench dav
Xav txog qhov project thiab cov txiaj ntsig ntxiv rau cov kav dej los ntawm lub ntiaj teb, qhov dav trench yuav tsum nqaim li sai tau.
Ib daim ntawv pom zoo trench widths. Cov txiaj ntsig no tau ua raws li cov hauv paus ntsiab lus uas qhov dav dav yuav tsum nqaim li qhov ua tau kom txo qis cov khoom siv sab nraud thiab cov nqi teeb tsa, thaum tseem muaj qhov chaw txaus los muab cov kev cog lus tshwj xeeb.
Qhov dav dav ntawm cov trench tau txais yuav raug cuam tshuam los ntawm cov av, cov txheej txheem sib koom ua ke, thiab seb cov pob qij txha tau ua nyob rau hauv lub trench.

Qhov twgPE tubraug teeb tsa nrog lwm cov kev pabcuam hauv cov xwm txheej trench, qhov dav trench yuav raug teev los ntawm cov cai tswjfwm hauv nroog kom tso cai rau kev saib xyuas tom qab.
Trench qhov tob
Qhov twgPE tubQib kab tsis tau teev tseg, lub hau npog rau saum cov kav dej PE yuav tsum tau teeb tsa kom muaj kev tiv thaiv txaus los ntawm kev thauj khoom sab nraud, kev puas tsuaj thib peb, thiab kev tsim kho tsheb.
Yog tias ua tau, cov kav dej yuav tsum tau muab tso rau hauv qhov tsawg kawg nkaus qhov tob thiab, raws li kev qhia, cov txiaj ntsig tau teev tseg hauv qab no yuav tsum tau txais yuav.

Saum av Installation
CHUANGRONG PE kav tej zaum yuav raug ntsia saum toj no hauv av rau kev siv siab thiab tsis siv siab nyob rau hauv ob qho tib si raug raug thiab tiv thaiv tej yam kev mob. Cov kav dej dub PE tuaj yeem siv rau hauv qhov chaw raug tshav ntuj ncaj qha yam tsis muaj kev tiv thaiv ntxiv. Qhov twg PE kav dej ntawm cov xim uas tsis yog dub yog siv nyob rau hauv cov xwm txheej, ces cov kav dej yuav tsum tau tiv thaiv los ntawm tshav ntuj. Qhov twg cov kav dej PE raug teeb tsa rau hauv cov xwm txheej raug raug, tom qab ntawd cov khoom siv PE nce ntxiv vim raug cuam tshuam yuav tsum raug coj mus rau hauv tus account hauv kev tsim cov kev ntsuas siab ntawm cov kav dej PE. Kev ntsuas kub hauv cheeb tsam xws li qhov sib thooj rau cov kab hluav taws xob, lub tshuab hluav taws xob, lossis cov khoom siv hluav taws xob yuav tsum raug zam tshwj tsis yog cov kav dej PE raug tiv thaiv zoo. Thaum siv cov khoom lag luam, cov no yuav tsum tsim nyog rau cov ntawv thov raug.
Cov ntaub pua chaw pw & Backfill
Cov pob zeb excavated trench yuav tsum tau muab tshem tawm, thiab tsis pub dawb los ntawm tag nrho cov pob zeb, thiab cov khoom tawv. Cov ntaub ntawv txaj siv hauv ob qho tib si trench thiab embankments yuav tsum yog ib qho ntawm cov hauv qab no:
1. Xuab zeb los yog av, dawb los ntawm cov pob zeb loj dua 15 hli, thiab cov av nplaum tawv tawv loj dua 75 hli.
2. Crushed pob zeb, gravel, los yog graded cov ntaub ntawv ntawm txawm grading nrog ib tug siab tshaj plaws loj ntawm 15 mm.
3.Excavated khoom dawb los ntawm pob zeb los yog zaub teeb meem.
4. Cov nplaum nplaum uas tuaj yeem txo qis dua 75 hli qhov loj.
Nyob rau hauv feem ntau ntawm PE yeeb nkab daim ntaub ntawv, tsawg kawg yog 75 hli ntawm cov ntaub pua tsev yog siv nyob rau hauv ob qho tib si trench thiab embankments nyob rau hauv av excavations. Rau excavations hauv pob zeb, 150 mm txaj txaj yuav tsum tau.
Cov seem ntawm lub trench, los yog embankment filling tej zaum yuav ua nrog rau yav tas los excavated haiv neeg cov ntaub ntawv.
Cov no yuav tsum tsis pub dawb los ntawm cov pob zeb loj, zaub, thiab cov khoom tsis huv, thiab tag nrho cov ntaub ntawv yuav tsum muaj qhov siab tshaj plaws particle loj tsawg dua 75 hli.
Qhov twg cov kav dej PE raug teeb tsa hauv thaj chaw uas muaj cov khoom siv sab nraud siab, tom qab ntawd cov khoom siv rov qab yuav tsum yog tus qauv zoo ib yam li cov ntaub pua chaw pw thiab cov ntaub ntawv overlay.
Thrust Blocks & Yeeb Nkab Restraint
Thrust blocks yuav tsum tau rau CHUANGRONG PE kav hauv cov ntawv thov siab qhov twg cov pob qij txha tsis tiv taus ntev loads. Cov thrust blocks yuav tsum tau muab nyob rau hauv tag nrho cov kev hloov nyob rau hauv cov kev taw qhia.
Qhov twg siv cov pob zeb ua vaj tse, cov ntsiab lus sib txuas ntawm cov yeeb nkab PE, los yog kev sib txuas thiab cov thrust block yuav tsum tau tiv thaiv kom tsis txhob puas PE. Roj hmab lossis malthoid sheeting tuaj yeem siv rau lub hom phiaj no.
Tag nrho cov fittings thiab cov khoom hnyav xws li cam khwb cia hlau li qub yuav tsum tau txais kev txhawb nqa txhawm rau tiv thaiv kev thauj khoom ntawm cov khoom PE. Tsis tas li ntawd, qhov twg siv li qub, lub torque loads tshwm sim los ntawm kev qhib / kaw haujlwm yuav tsum tau tawm tsam nrog kev txhawb nqa thaiv.
Curving ntawm PE Pipelines
Tag nrho cov kav dej PE ntsia rau ntawm txoj kab nkhaus yuav tsum tau kos kom sib npaug ntawm tag nrho qhov nkhaus ntev, thiab tsis dhau ib ntu luv. Qhov no tuaj yeem ua rau kinking hauv txoj kab me me, thiab / lossis cov kav dej nyias nyias.
Loj txoj kab uas hla PE kav (450mm thiab saum toj no) yuav tsum tau koom ua ke, thiab ces kos tusyees mus rau lub vojvoog uas xav tau. Qhov tsawg kawg nkaus tso cai khoov vojvoog ntawm HDPE kav dej tuaj yeem pom.
Relining & Non-dig Trench
Cov kav dej uas twb muaj lawm tuaj yeem kho dua tshiab los ntawm kev ntxig cov kav dej CHUANGRONG PE rau hauv cov kav dej qub. Insertion kav yuav rub mus rau hauv txoj hauj lwm los ntawm mechanical winches. Relining nrog PE kav dej muab cov qauv tsim uas muaj peev xwm tiv taus lub siab sab hauv lossis sab nraud tsis muaj kev cia siab rau qhov seem ntawm lub zog ntawm cov yeeb nkab qub.
Cov kav dej PE yuav tsum tau ntev ntev inlet thiab tawm trenches kom haum rau PE yeeb nkab vojvoog kom coj mus rau hauv cov kav dej uas twb muaj lawm, thiab lub winch sib dhos siv los rub cov PE liner raws cov kav dej. Qhov tsawg kawg nkaus khoov vojvoog ntawm PE liner tuaj yeem suav tau raws li tau piav qhia hauv Pipeline Curvature ntawm phau ntawv.
PE kav kuj tuaj yeem siv rau hauv cov haujlwm tsis yog khawb, xws li Kab rov tav Directional Drilling (HDD). Qee qhov kev siv ntxov tshaj plaws ntawm txoj kab uas hla PE yeeb nkab hauv kev taw qhia drilling yog rau kev hla dej. PE yeeb nkab haum rau cov kev teeb tsa no vim nws qhov kev tiv thaiv khawb thiab cov fused sib koom ua ke uas muab cov xoom-leak-tus nqi sib koom nrog tsim tensile muaj peev xwm sib npaug ntawm cov yeeb nkab.
Txog niaj hnub no, cov kev taw qhia drillers tau teeb tsa PE yeeb nkab rau cov pa roj, dej, thiab cov kav dej phwj; hluav taws xob conduits; thiab ntau yam kab mob.
Cov dej num no koom nrog tsis yog kev hla dej xwb tab sis kuj tseem muaj kev hla kev loj thiab txoj cai-ntawm-txoj kev los ntawm cov chaw tsim kho kom tsis txhob cuam tshuam txoj kev, kev tsav tsheb, thiab kev nkag mus rau kev lag luam.
Kev kho thiab tu
Raws li kev puas tsuaj sib txawv, muaj ntau hom kev kho tshuab xaiv. Kev kho tuaj yeem ua tiav ntawm cov kav dej me me los ntawm kev qhib qhov chaw trench txaus thiab txiav tawm qhov tsis xws luag. Hloov cov seem uas puas lawm nrog ib ntu tshiab ntawm cov yeeb nkab.
Kev kho cov kav dej loj loj tuaj yeem ua tiav nrog flanged spool piece. Qhov kev puas tsuaj raug tshem tawm.Tom ntej no, lub pob tw fusion tshuab yog qis rau hauv qhov ditch.Flanged kev sib txuas yog fused rau txhua qhov qhib kawg, thiab flanged spool sib dhos yog bolted rau hauv qhov chaw. Lub flanged spool yuav tsum raug ua kom haum rau qhov sib txawv hauv cov kav dej.
