Fnoj
Geotextile yog cov khoom siv geosynthetic permeable uas muaj nyob nruab nrab ntawm cov av thiab cov kav dej, gabions, los yog khaws cov phab ntsa, txhim kho cov dej txav thiab cuam tshuam cov av txav.
Qhov ntev filament geotextile yog ua los ntawm high-strength polyester chips raws li raw cov ntaub ntawv, uas yog txau, stretched los ntawm huab cua ntws, pw nrog mesh, pre pressed, thiab koob punched.
- Kev ua tau zoo ntawm lub cev ruaj khov, muaj peev xwm tswj tau qhov kev ua haujlwm qub rau lub sijhawm ntev;
- Cov khoom siv ruaj khov nrog cov kua qaub thiab alkali tsis kam; Zoo permeability;
- Kev kub siab ua haujlwm, tiv thaiv txias, thiab yoog mus rau qhov sib txawv sab nraud;
- Lub teeb yuag, tuaj yeem ntim, thauj, thiab khaws cia raws li qee qhov kev xav tau, thiab kev tsim kho yooj yim.
Cov txheej txheem ntau lawm
Cov koob punched non-woven npuag series cov khoom yog tsim los ntawm kev sib tsoo zoo, ntau yam koob meej punctures, lossis kev kho kub kub uas tsim nyog. Ntev filament koob punched non-woven npuag yog txheej txheem ntawm weaving thiab nteg dav hlau stretched fibers mus rau hauv ib tug fiber mesh, ces ua ntej nias lub fiber mesh los ntawm ib tug overheated rau cov menyuam thiab ntxiv dag zog rau hauv cov ntaub los ntawm ib rab koob. Cov koob muaj hooks thiab pos, thiab cov fiber ntau mesh yog rov punctured thiab ntxiv dag zog nrog hooks thiab straps los tsim ib rab koob punched non-woven npuag.

07 Lwm cov haujlwm
Ntev filament non-woven geotextiles tuaj yeem ua ke nrog lwm cov ntaub ntawv geosynthetic xws li geogrids, geomembranes, cov kav dej, thiab lwm yam los tsim cov geotextiles sib xyaw. Composite geotechnical cov ntaub ntawv tuaj yeem muab cov khoom sib txawv ntawm cov khoom sib txawv, ua tau raws li cov kev xav tau ntawm cov khoom siv tshwj xeeb, thiab ua si ntau yam haujlwm. Composite geogrid yog cov khoom sib xyaw geosynthetic ua los ntawm cua sov thiab sib txuas geotextiles thiab yas geogrids. Geogrid muaj lub siab tensile modulus, uas tuaj yeem muab kev kaw ruaj khov thiab kev txhawb zog, thaum cov ntaub tsis-woven ua kom pom kev ua haujlwm ntawm cov khoom sib xyaw. Lwm qhov piv txwv yog cov kua dej sib xyaw ua ke, uas yog cov khoom siv dej sib xyaw ua ke ntawm cov khoom siv tsis-woven geotextile thiab cov kav dej. Kev sib xyaw ua ke ntawm geotextile (filtration function) thiab peb-dimensional geotextile drainage network (drainage and load dispersion function) muab tag nrho pom, kua dej, thiab kev tiv thaiv. Geotextile tuaj yeem muab kev ua haujlwm ntawm dej / av lim txheej thiab tiv thaiv cov av nplaum thiab cov khoom ntim saum toj no los ntawm kev nkag mus rau hauv cov dej ntws hauv cov tub ntxhais kawm, yog li ua kom nws lub peev xwm mus ntev.
