Txhawm rau pab txhawb kev tso thiab kev thauj mus los ntawm cov khoom siv kho qhov muag, thaum lub tshuab kho qhov muag tawm ntawm lub Hoobkas, txhua qhov axis tuaj yeem dov rau 2-3 mais.Thaum tso cov kab hluav taws xob kho qhov muag ntev ntev, nws yog qhov tsim nyog los txuas cov kab hluav taws xob ntawm cov kab sib txawv.Txhawm rau kom yooj yim rau kev sib txuas, stripping yog qhov tsim nyog.GL tau koom nrog hauv kev lag luam fiber ntau optic cable rau ntau tshaj 17 xyoo.Peb tuaj yeem sau qee cov ntaub ntawv tseem ceeb.Niaj hnub no peb yuav txheeb xyuas qhov zoo ntawm polyethylene sheathed (PE) fiber optic cable tiv thaiv kav.
1. Cov khoom zoo ntawm lub cev yog tsim nrog cov khoom zoo polyethylene raw khoom.Nws tsis tsuas yog zoo rigidity, lub zog, tab sis kuj zoo saj zawg zog, uas yog conducive rau lub installation ntawm pipelines.
2. Kev tiv thaiv corrosion thiab kev pab lub neej ntev: Hauv cov chaw ntug dej hiav txwv, cov dej hauv av yog siab thiab cov av humidity siab.Kev siv cov hlau los yog lwm cov kav dej yuav tsum muaj kev tiv thaiv corrosion.Thiab lub neej kev pab cuam feem ntau tsuas yog 30 xyoo, thiab PE yeeb nkab tuaj yeem tiv taus ntau yam tshuaj lom neeg, thiab tsis cuam tshuam los ntawm av corrosion.
3. Zoo toughness thiab yooj.PE yeeb nkab yog ib hom high-toughness yeeb nkab nrog ib tug tawg elongation ntawm ntau tshaj 500%.Nws muaj zog heev adaptability rau cov av tsis sib xws thiab dislocation ntawm lub hauv paus.Kev poob siab zoo.Cov kav dej me me tuaj yeem khoov tau arbitrarily.
4. Cov yeeb nkab phab ntsa yog du, kev sib txhuam coefficient yog me me, lub cable yog yooj yim rau nqos, thiab lub sij hawm siv tau zoo.
5. Kev ua haujlwm zoo ntawm cov hluav taws xob rwb thaiv tsev, kev ua haujlwm ntev (cov kav dej faus rau ntau tshaj 50 xyoo), kev ua haujlwm ruaj khov, muaj kev nyab xeeb thiab txhim khu kev qha.
6. Lub teeb yuag, kev saib xyuas, kev teeb tsa thiab kev tsim kho, kev saib xyuas yooj yim, yooj yim rau kev thauj thiab khiav lag luam.
7. Cov kav dej me me tuaj yeem ua tau coiled, nrog rau cov yeeb nkab ntev, ob peb pob qij txha, thiab yooj yim installation.
8. Cov yeeb nkab tuaj yeem ua rau ntau yam xim kom pom qhov sib txawv.
9. Zoo heev uas tsis muaj qhov kub thiab txias tsis kam.PE qhov kub-kub embrittlement kub yog qhov tsawg heev, thiab nws tuaj yeem siv tau zoo nyob rau hauv qhov kub ntawm 20-40.Thaum lub sij hawm tsim kho nyob rau hauv lub caij ntuj no, cov yeeb nkab yuav tsis nkig vim muaj kev cuam tshuam zoo ntawm cov khoom.
10. PE yeeb nkab nrog zoo hnav tsis kam yog piv nrog rau lwm cov yeeb nkab hlau.Qhov hnav tsis kam yog 4 npaug ntawm cov kav hlau.
11. Ntau yam kev tsim kho tshiab.Ntxiv nrog rau txoj kev khawb ib txwm, PE kav kuj tuaj yeem tsim nrog ntau yam tshiab trenchless technologies, xws li cov yeeb nkab jacking, liner yeeb nkab, thiab cov yeeb nkab sib cais.Qhov no yog tib qhov chaw uas tsis pub excavation.s Xaiv.
Yog tias koj txaus siab rau peb cov khoom, lossis xav tau cov ntaub ntawv xov xwm ntxiv, pls tiv tauj nrog peb, GL yuav txuas ntxiv txheeb xyuas thiab teb cov lus nug rau txhua tus neeg, thiab muab qee qhov kev pom tshwj xeeb.
