1. Taw qhia
1.1 Gabion Basket yog dab tsi?
Lub pob tawb gabion yog cov qauv hlau mesh uas muaj cov pob zeb lossis pob zeb, dav siv hauv kev tsim vaj tsev thiab hydraulic rau txoj kab nqes stabilization, kev tiv thaiv ntug dej, thiab kev tiv thaiv kev yaig. Nws ua ke ntawm cov qauv kev ruaj ntseg, permeability, thiab struts adaptability ua rau nws ib tug nrov engineering tov.
1.2 General Life Expectancy
Gabion pob tawb lub neej expectancy txawv heev, feem ntau yog li ntawm 20 mus rau 50 xyoo nyob rau hauv ib txwm muaj mob. Ib puag ncig hnyav lossis cov khoom siv tsis zoo / kev tsim kho tuaj yeem ua rau luv luv rau qis dua 15 xyoo, thaum siab - cov ntaub ntawv zoo thiab kev saib xyuas yuav ua rau nws ntev dua 70 xyoo.
2. Yam tseem ceeb cuam tshuam
2.1 Mesh Khoom Zoo
Cov khoom siv mesh yog qhov tseem ceeb. Uncoated low- carbon steel kav tsuas yog 5-10 xyoo. Cov txheej txheem galvanized steel (Ntau dua lossis sib npaug ntawm 85g / m² zinc txheej) txuas lub neej mus rau 20-30 xyoo, thaum hnyav galvanization (Ntau dua lossis sib npaug ntawm 200g / m²) ua tiav 30-50 xyoo. PVC/PE-coated galvanized steel muaj superior corrosion kuj, kav ntev li 40-70 xyoo, zoo tagnrho rau hnyav ntug hiav txwv dej los yog acid{15}} puag ncig av puag ncig.
2.2 Ib puag ncig tej yam kev mob
Qhuav hauv av nrog cov av nruab nrab txo qis corrosion, cia siab tshaj plaws kev pab cuam lub neej. Cov chaw ntub dej (cov cheeb tsam los nag, cov ntug dej hiav txwv) nce corrosion, txo lub neej los ntawm 10-30%. Cov chaw muaj corrosive heev (ntev ntsev tsuag tsuag, muaj kua qaub los nag, ntsev-alkali av) tuaj yeem txiav lub neej ntau dua 50% yam tsis muaj kev tiv thaiv tshwj xeeb.
3. Lub neej zoo nyob rau hauv cov ntawv thov loj
Nyob rau hauv txoj kab nqes hav ruaj khov thiab tuav cov phab ntsa, hnyav galvanized mesh kav ntev li 30-50 xyoo, thiab PVC / PE-coated mesh 50-70 xyoo. Rau kev tiv thaiv ntug dej hiav txwv thiab kev tswj dej nyab, cov txheej txheem galvanized mesh ua haujlwm 20-30 xyoo, thaum PVC / PE-coated mesh kav 30-50 xyoo. Cov phiaj xwm ntug dej hiav txwv pom 10-15 xyoo rau cov galvanized mesh, 15-25 xyoo rau hnyav galvanized, thiab 25-50 xyoo rau PVC / PE-coated los yog stainless hlau mesh. Hauv cov chaw lag luam / mining, zoo tib yam galvanized mesh kav ntev dua 10 xyoo, thaum tshwj xeeb coated PVC / PE mesh ua tiav 15-25 xyoo.
4. Kev ua kom lub neej ntev
Xaiv cov ntaub ntawv sib piv rau ib puag ncig: tus qauv galvanized rau thaj chaw me me, hnyav galvanized rau thaj chaw ntub dej, thiab PVC / PE-coated los yog stainless hlau rau qhov chaw muaj corrosive heev. Xyuas kom tus qauv tsim kom tsis txhob muaj kev puas tsuaj mesh thiab xyuas kom zoo pob zeb txhaws thiab kev sib txuas ruaj khov. Kev saib xyuas tsis tu ncua, suav nrog kev kho cov mesh puas, rov ua cov pob zeb, thiab ntxuav cov khib nyiab, kuj ua rau lub neej ua haujlwm tau zoo.
