1. Geosynthetic cov ntaub ntawv muaj xws li: geonet, geogrid, geomold hnab, geotextile, geocomposite ntws cov ntaub ntawv, fiberglass mesh, geomat thiab lwm yam.
2. Nws siv yog:
1 》Kev txhawb nqa
(1) Lub hom phiaj tseem ceeb ntawm embankment reinforcement yog los txhim kho kev ruaj ntseg ntawm embankment;
(2) Lub hauv paus ntsiab lus ntawm kev tsim kho ntawm cov embankment yog muab kev ua si tag nrho rau qhov kev txhawb zog raws li qhov pib. Cov khoom siv geosynthetic yuav tsum tau ntim rau hauv 48 teev tom qab paving kom tsis txhob raug tshav ntuj ncaj qha rau lub sijhawm ntev.
2 》Txhim kho ntawm backfill roadbed
Lub hom phiaj ntawm kev siv geosynthetics los txhawb cov subgrade backfill yog los txo qhov tsis sib xws ntawm cov subgrade thiab cov qauv. Qhov tsim nyog qhov siab ntawm lub platform txhawb nqa rov qab yog 5.0 ~ 10.0m. Cov khoom siv txhawb nqa yuav tsum yog geonet lossis geogrid.
3》 Lim thiab kua dej
Raws li lub lim dej thiab lub cev ntws tawm, nws tuaj yeem siv rau kev tiv thaiv culverts, seepage ditch, txoj kab nqes saum npoo, rov qab ntws ntawm cov qauv phab ntsa, thiab cov dej hauv ncoo rau ntawm qhov chaw mos ntawm lub hauv paus embankment; nws kuj tuaj yeem siv los kho qhov kev hloov pauv ntawm cov av nkos thiab cov av khov raws caij nyoog, thiab lwm yam hauv kev tsim kho vaj tse.
4) 》Subgrade tiv thaiv
(1) Kev tiv thaiv subgrade.
(2) Kev tiv thaiv txoj kab nqes - txhawm rau tiv thaiv cov av lossis pob zeb slopes uas yooj yim puas los ntawm tej yam ntuj tso; kev tiv thaiv scour - los tiv thaiv cov dej ntws los ntawm scouring thiab scouring lub roadbed.
(3) Txoj kab nqes ntawm txoj kab nqes kev tiv thaiv kev tiv thaiv av yuav tsum nyob nruab nrab ntawm 1: 1.0 thiab 1: 2.0; txoj kab nqes ntawm kev tiv thaiv pob zeb yuav tsum tau qeeb dua 1: 0.3. Rau kev tiv thaiv av nqes hav, cog, kev tsim kho thiab kev saib xyuas ntawm turf yuav tsum ua kom zoo.
(4) Kev tiv thaiv Scour
Cov khoom siv ntawm lub cev yuav tsum yog polypropylene woven geotextile. Rau kev tiv thaiv ntawm geotextile mos lub cev sinking thiab kua dej, kev ruaj ntseg ntawm lub cev dej yuav tsum tau xyuas thiab xam nyob rau hauv peb yam: anti-floating, anti-slipping ntawm nias thaiv ntawm lub cev ntws, thiab anti-slipping ntawm tag nrho cov kua. lub cev.
