Cov khoom siv geotextile uas muaj zog thiab muaj zog heev, ua los ntawm polyester filament.
Kev Piav Qhia Luv:
Filament woven geotextile yog ib hom geomaterial muaj zog ua los ntawm cov khoom siv hluavtaws xws li polyester lossis polypropylene tom qab ua tiav. Nws muaj cov khoom zoo heev xws li kev tiv thaiv tensile, kev tiv thaiv kua muag thiab kev tiv thaiv kev tawg, thiab tuaj yeem siv rau hauv kev tswj av, kev tiv thaiv dej ntws, kev tiv thaiv xeb thiab lwm yam teb.
Cov Khoom Piav Qhia
Filament woven geotextile yog ib qho kev faib tawm ntawm geotextile, nws yog cov khoom siv hluavtaws muaj zog ua cov khoom siv raw, los ntawm kev tsim cov txheej txheem weaving, yog ib hom textile feem ntau siv hauv kev tsim kho vaj tse. Nyob rau hauv xyoo tas los no, nrog rau kev ua kom nrawm ntawm kev tsim kho vaj tse thoob plaws lub tebchaws, qhov kev thov rau filament woven geotextiles kuj nce ntxiv, thiab muaj peev xwm ua lag luam zoo heev. Tshwj xeeb tshaj yog nyob rau hauv qee qhov kev tswj hwm dej loj thiab kev hloov pauv, kev tsim kho kev txuag dej, txoj kev loj thiab choj, kev tsim kho tsheb ciav hlau, tshav dav hlau wharf thiab lwm yam kev lag luam engineering, muaj ntau yam kev siv.
Cov Lus Qhia Tshwj Xeeb
Lub zog tawg nominal hauv MD (kN / m): 35, 50, 65,8 0, 100, 120, 140, 160, 180, 200, 250, dav hauv 6m.
Vaj tse
1. Muaj zog heev, tsis yooj yim hloov pauv.
2. Kev ruaj khov: khoom ruaj khov, tsis yooj yim rau kev daws teeb meem, cua slaked thiab tuaj yeem khaws cov khoom qub ntev.
3. Tiv thaiv kev yaig: tiv thaiv kua qaub, tiv thaiv alkali, tiv thaiv kab thiab pwm.
4. Kev nkag tau: tuaj yeem tswj tau qhov loj ntawm lub sieve kom khaws tau qee qhov kev nkag tau.
Daim Ntawv Thov
Nws yog siv dav hauv dej ntws, ntug dej hiav txwv, chaw nres nkoj, txoj kev loj, kev tsheb ciav hlau, chaw nres nkoj, qhov av, choj thiab lwm yam kev tsim kho geotechnical. Nws tuaj yeem ua tau raws li txhua yam kev xav tau geotechnical xws li kev lim dej, kev sib cais, kev txhawb zog, kev tiv thaiv thiab lwm yam.
