1. Cov khoom lag luam thiab kev ua haujlwm ntawm cov yeeb nkab coated
Raws li kev ua haujlwm ntawm cov kabmob siab thiab kev thauj mus los, cov txheej txheem ua haujlwm ntawm cov yeeb nkab coated plays lub luag haujlwm tiv thaiv thiab pabcuam, thiab tuaj yeem rub tawm ntawm cov yeeb nkab lub cev thaum siv.
Raws li qhov yuav tsum tau muaj ntawm GB / T 15558.1-2015 thiab GB / T 13663.2-2018, cov yeeb nkab ua haujlwm hauv cov yeeb nkab coated yuav tsum ua kom tau raws li qhov yuav tsum tau ua hauv cov qauv no, xws li qhov loj me, hydrostatic zog, oxidation induction lub sij hawm, tsis kam mus qeeb. kev loj hlob tawg, thiab lwm yam.
1.2 PE kav dej nrog cov txheej txheem thermoplastic tiv thaiv coated rau sab nrauv phab ntsa
PE yeeb nkab nrog peelable thermoplastic tiv thaiv txheej loj rau lub txheej phab ntsa (hereinafter xa mus rau raws li coated yeeb nkab) hais txog cov yeeb nkab uas yuav siv sij hawm ib txheej PE yeeb nkab raws li cov ua hauj lwm cov yeeb nkab thiab extrudes ib tug tiv thaiv txheej ntawm ntaub ntawv sib txawv sab nraum cov ua hauj lwm cov yeeb nkab los ntawm ntau txheej txheej coextrusion technology. Raws li ib feem ntawm lub siab bearing thiab conveying nruab nrab, txheej tiv thaiv plays lub luag hauj lwm tiv thaiv, thiab qhov chaw nres nkoj yuav stripped los ntawm cov yeeb nkab ua hauj lwm thaum vuam.
1.3 Cov yam ntxwv tseem ceeb ntawm cov yeeb nkab coated Cov yeeb nkab
coated daws qhov teeb meem uas cov yeeb nkab PE yog ib qho yooj yim rau khawb hauv cov txheej txheem trenchless, thiab tuaj yeem tiv thaiv cov yeeb nkab ua haujlwm zoo. Cov thev naus laus zis tseem ceeb yog txheej txheej tiv thaiv. Raws li kev siv cov khoom siv raw thiab cov qauv, kev siv cov khoom siv siab elastic modulus polypropylene (PP) tuaj yeem tsis tsuas yog txhim kho qhov khawb ntawm cov txheej tiv thaiv, tab sis kuj tiv thaiv nws los ntawm kev sib txuas nrog cov yeeb nkab ua haujlwm thiab pab txhawb kev stripping. Hauv cov theem tsim khoom, cov txheej txheem tiv thaiv nrog qhov ntev ntawm 300 hli ntawm ob qhov kawg ntawm cov yeeb nkab cladding yuav tsum tau prefabricated thiab indented los pab txhawb lub stripping ntawm txheej tiv thaiv thaum lub sij hawm tsim kho. Nyob rau hauv cov nqe lus ntawm kev tiv thaiv crater, lub stripped tiv thaiv txheej yog rov qab mus rau lub stripped seem tom qab vuam thiab qhov txhab nrog fiber-reinforced daim kab xev.
1.5 Cov khoom siv ntawm cov yeeb nkab coated
Los ntawm kev sib piv cov kev ua haujlwm tsis zoo ntawm PE raw cov ntaub ntawv thiab PP raw cov ntaub ntawv, lub zog tensile, khoov modulus thiab hardness ntawm PP cov ntaub ntawv yog siab dua cov ntaub ntawv PE. Kev khawb ntawm cov ntaub ntawv PP yog cov ntaub ntawv PP nyuaj dua li cov ntaub ntawv PE.Yog li ntawd, cov khoom siv PP yog siv los ua txheej txheej tiv thaiv kom tsis txhob khawb rau sab nrauv ntawm PE ua haujlwm yeeb nkab hauv trenchless siv.
2. Kev ua tau zoo ntawm cov khoom siv
rau cov kav dej polyethylene dav siv hauv kev lag luam roj thiab dej, kev puas tsuaj rau cov kav dej los ntawm kev thauj mus los ntawm cov yeeb nkab, kev thauj khoom thiab kev thauj mus los, kev tsim kho thiab ib puag ncig yam tsis muaj kev cuam tshuam. Cov kav dej coated tuaj yeem tiv thaiv cov kav dej ua haujlwm tau zoo, txhim kho ntau yam teeb meem uas tau ntsib hauv kev siv tswv yim los ntawm cov cuab yeej tshwj xeeb scraping thiab vuam txoj kev, thiab muaj kev cuam tshuam cov txiaj ntsig hauv qab no:
Tiv thaiv cov yeeb nkab ua haujlwm, txo qhov khawb thiab txhim kho kev nyab xeeb ntawm cov kav dej. Cov txheej txheej tiv thaiv sab nrauv tuaj yeem tiv thaiv kev laus ntawm cov raj ua haujlwm los ntawm cov kab hluav taws xob ultraviolet thiab ua kom lub sijhawm cia ntawm lub raj ua haujlwm. Cov txheej kuj muaj qhov nthuav dav, xws li ntxiv cov tshuaj tiv thaiv zoo li qub, tiv thaiv kab mob, qhov chaw, kev tshawb nrhiav thiab lwm yam haujlwm.
3. Daim ntawv thov ntawm cov yeeb nkab coated nyob rau hauv trenchless nteg
Cov tsoos excavation nteg pipeline kev tsim kho txoj kev tau ntau thiab ntau txwv vim lub inconvenience ntawm lub nroog thiab nruj me ntsis raws li txoj cai ntawm lub nroog tswj. Lub trenchless siv tshuab txuas ntxiv tsim thiab nrov. Nyob rau tib lub sijhawm, nrog rau qhov tshwm sim ntawm cov yeeb nkab coated, nws tuaj yeem ua kom muaj zog ntawm txheej txheej txheej, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm trenchless nteg thiab steel yeeb nkab interspersed kho.
CJJ 358-2018 polyethylene yeeb nkab rau Trenchless Engineering (tso rau kev pom zoo) ntxiv coated yeeb nkab cov khoom, thiab tso rau pem hauv ntej cov kev cai rau cov khoom ua tau zoo ntawm peelable polypropylene (PP) txheej tiv thaiv coated rau sab nrauv phab ntsa ntawm trenchless engineering.
Nws zoo daws qhov teeb meem ntawm kev puas tsuaj los ntawm khawb ntawm cov pob zeb hauv av thaum lub sij hawm thauj mus los thiab kev teeb tsa, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem ntawm trenchless hla, thiab muab tau cov kab rov tav directional drilling hla nrog cov kav dej loj dua SDR11 Series yav tom ntej. Cov no tsim cov cib fim thiab cov xwm txheej rau kev ua si tag nrho rau qhov zoo ntawm polyethylene (PE) thiab rau kev rov ua dua tshiab thiab kho cov kav dej qub hauv cov seem uas tsis tsim nyog rau kev khawb.
4. Cov ntsiab lus
Cov yeeb nkab coated muab cov kev daws teeb meem tshiab rau cov yeeb nkab khawb qhov teeb meem ntawm PE yeeb nkab hauv kev thauj mus los thiab kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv trenchless siv. Coated yeeb nkab muaj qhov zoo zoo hauv trenchless tso cov raj xa dej. Nrog rau kev tsim kho ntau ntxiv ntawm trenchless tso ntawm cov raj xa hluav taws xob, cov yeeb nkab coated muaj kev lag luam dav dav.
