High Strength Weave Geotextiles Nrog Zoo Stability
Weave geotextile yog ua los ntawm polypropylene, polypropylene thiab polyethylene tiaj yarns raws li raw cov ntaub ntawv, thiab muaj tsawg kawg yog ob txheej ntawm parallel yarns (los yog ca yarns).Ib pab pawg hu ua warp yarn raws longitudinal direction of the loom (the direction in which the fabric travels) Txoj kev kab rov tav hu ua weft.Lub warp yarn thiab weft yarn yog woven rau hauv ib daim ntaub zoo nrog cov khoom sib txawv thiab cov txheej txheem, uas tuaj yeem woven rau hauv cov thicknesses sib txawv thiab ntom raws li cov ntawv thov sib txawv, nrog kev ruaj ntseg zoo.

Khoom nta
1. Lub zog muaj zog, tsis tshua muaj elongation, kev laus ua haujlwm, tsis yooj yim los tsim kua muag
2. Tiv thaiv cov nyom, kab, tiv thaiv kev yaig, tiv thaiv av yaig
3. Tiv thaiv cov xuab zeb zoo thiab cia dej thiab cua nkag mus
4. Acid thiab alkali tsis kam, muaj zog txias tsis kam, nrog huab cua tsis kam
Daim ntawv thov
1. Siv nyob rau hauv tej yaam num pob zeb xws li txoj kev loj, railways, tshav dav hlau, pob zeb dams, breakwaters, retaining phab ntsa, backfills, ciam teb, thiab lwm yam, kom disperse av kev nyuaj siab kom cov av modulus, txwv cov av slippage, thiab txhim kho stability.
2. Tiv thaiv cov embankment kom tsis txhob raug cua, nthwv dej, tides thiab los nag, thiab siv rau kev tiv thaiv ntug dej, kev tiv thaiv txoj kab nqes, tiv thaiv hauv qab, thiab tiv thaiv av yaig.
3. Nws yog siv los ua cov txheej lim dej ntawm embankments, dams, cov dej ntws thiab cov pob zeb ntug hiav txwv, cov av slopes, thiab tuav cov phab ntsa kom tsis txhob muaj cov xuab zeb thiab cov av qeeg dhau mus, thaum tso dej los yog cua nkag mus tau dawb.
Nco tseg
1. Geotextiles tsuas tuaj yeem txiav nrog rab riam geotextile (nqa riam).Yog tias txiav ua tiav ntawm qhov chaw, kev tiv thaiv tshwj xeeb yuav tsum tau ua rau lwm cov ntaub ntawv los tiv thaiv kev puas tsuaj tsis tsim nyog los ntawm kev txiav geotextiles;
2. Nyob rau tib lub sij hawm raws li geotextile tau muab tso, tag nrho cov kev ntsuas tsim nyog yuav tsum tau coj los tiv thaiv kev puas tsuaj rau cov khoom hauv qab no;
3. Thaum tso geotextiles, xyuam xim tsis txhob cia lwm cov ntaub ntawv xws li pob zeb, cov plua plav loj lossis cov dej noo uas yuav ua rau cov geotextiles puas, thaiv cov dej los yog cov lim dej, lossis ua rau cov kev sib txuas tom ntej nyuaj;
4. Tom qab kev teeb tsa, pom lub ntsej muag ntawm txhua qhov geotextile txhawm rau txheeb xyuas tag nrho cov av puas, kos thiab kho, thiab xyuas kom meej tias tsis muaj lwm yam khoom ntawm qhov chaw uas tuaj yeem ua rau puas tsuaj, xws li cov koob tawg;
5. Kev sib txuas ntawm geotextiles yuav tsum ua raws li cov cai hauv qab no: Raws li ib txwm muaj, yuav tsum tsis muaj kev sib txuas kab rov tav ntawm txoj kab nqes (qhov kev sib txuas yuav tsum tsis txhob cuam tshuam nrog txoj kab nqes contour), tshwj tsis yog qhov chaw kho.
6. Yog tias siv cov sutures, cov sutures yuav tsum tau ua los ntawm tib yam lossis ntau dua li cov khoom siv geotextile, thiab cov sutures yuav tsum tau ua los ntawm cov khoom siv tshuaj uv resistant.Yuav tsum muaj cov xim sib txawv ntawm cov sutures thiab geotextiles kom yooj yim rau kev soj ntsuam.
7. Kev saib xyuas tshwj xeeb yuav tsum tau ua thaum lub sijhawm teeb tsa kom ntseeg tau tias tsis muaj pob zeb los ntawm cov av lossis pob zeb npog nkag mus rau hauv nruab nrab ntawm geotextile.
