Koob ntsiab punched geotextile

Cov ntsiab lus geotextile yog polyester filament koob-punched tsis-woven geotextile, uas tsis muaj tshuaj lom neeg thiab tsis muaj tshuaj kho cua sov. Nws yog cov khoom siv hauv tsev ib puag ncig.

Cov yam ntxwv

Nws tuaj yeem hloov cov qauv kev siv engineering ib txwm thiab cov txheej txheem kev tsim kho, ua rau kev tsim vaj tsev nyob nyab xeeb, thiab pab txhawb kev tiv thaiv ib puag ncig, thiab daws cov teeb meem yooj yim hauv kev tsim vaj tsev yam kev lag luam, kev lag luam zoo thiab tas mus li.

Cov lim geotextile muaj cov yam ntxwv zoo ua haujlwm, dej zoo permeability, kev txhim kho corrosion, tiv thaiv kev laus, cais tawm, lim, pov tseg, tiv thaiv, ruaj khov, txhawb nqa, thiab lwm yam Nws tuaj yeem hloov kho qhov tsis sib txig puag txheej thiab tiv thaiv kev tsim kho sab nraud. Kev rhuav tshem, nkag yog qhov me me, thiab qhov qub muaj nuj nqi tseem tuaj yeem tswj hwm nyob rau hauv kev thauj ntev.

Ntsiab lus geotextile ntsiab lus:

1. Lub zog - nyob hauv qhov hnyav sib xws, qhov muaj zog tensile yog siab dua lwm cov koob uas tsis muaj rab koob;

UV-resistant lub teeb - tsis tshua muaj siab UV tsis kam;

2. Tshaj kub hnyav tsis kam - siab kub tsis kam txog 230 ° C, tswj cov qauv teeb tsa thiab lub cev qub zog ntawm qhov kub siab;

3. Kev tso cai thiab tiaj tiaj tiaj - Geotextiles yog cov tuab thiab rab koob, nrog cov dej ntws zoo thiab ua kua dej permeability siab, thiab tuaj yeem tswj tau qhov kev ua tau zoo no tom qab ntau xyoo;

4. Creep tsis kam - geotextile creep tsis kam yog lub zog zoo dua li lwm cov geotextiles, yog li nws muaj kev ua haujlwm ntev ntev. Nws tiv thaiv yaig ntawm cov tshuaj feem ntau hauv cov av thiab kom xeb los ntawm roj av, diesel thiab cov zoo li;

5. Kev nthuav dav - qhov geotextile muaj qhov zoo elongation nyob rau hauv qee qhov kev ntxhov siab, yog li nws tuaj yeem hloov mus rau qhov chaw tsis xwm yeem ntawm qhov tsis sib xws;

Cov yam ntxwv kev ua haujlwm ntawm filament geotextile : lub tuab tuab geotextile tuaj yeem ua kom muaj qhov muaj peb sab ntawm qhov tsis sib luag ntawm geotextile, uas yog txhawb rau qhov ua tiav ntawm qhov ua tau zoo ntawm hydraulic. Lub zog topping ntawm geotextiles muaj qhov zoo, tshwj xeeb tshaj yog rau khaws cov phab ntsa thiab cov kav dej. Cov khoom siv geotextiles tau dhau lub teb chaws cov qauv thiab yog cov ntaub ntawv pov tseg zoo ntawm geotechnical.

Thov

(1) Lub zog ua kom tiav nyob rau hauv backfilling ntawm khaws phab ntsa, lossis vaj huam sib luag siv los thauj tog rau nkoj tuav phab ntsa. Ua ib txheej txheem qhwv lossis khaws tseg.

(2) Txhim kho txoj hauv kev yooj yim hloov kho, kho cov kab nrib pleev ntawm txoj kev, thiab tiv thaiv txoj hauv kev ntawm txoj kev kom tsis txhob tawg.

(3) Ua kom ruaj khov ntawm pob zeb txoj kab nqes thiab ntxiv cov av tiv thaiv kom tsis txhob muaj cov av hauv av thiab khov ntawm cov av thaum lub sijhawm kub.

(4) Txheej txheej cais tawm ntawm txoj kev ntawm txoj kev thiab ntawm txoj kev, lossis txheej txheej cais tawm ntawm txoj kab kev thiab qhov chaw mos.

(5) Kev sib cais, tiv thaiv pom thiab ua kom zoo dua ntawm cov khoom siv dag sau, pob zeb zeb los yog cov khoom siv thiab lub hauv paus, sib cais sib txawv ntawm cov av sib txawv khov.

(6) Lub lim txheej ntawm qhov pib teeb tsa lub qhov dej saum npoo ntawm lub tshauv ntim pas dej lossis cov pas dej sauv, thiab lub lim txheej ntawm lub kaw dej nyob hauv qhov chaw txhawm rau rov qab tuav phab ntsa.

(7) Cov dej ntws tso nyob ib puag ncig ntawm cov kua dej tsaus nti lossis cov txia kua ua kua tsaus tso.
