I-filament yolukiweyo ye-geotextile ephothiweyo enamandla aphezulu eqinisiweyo
Inkcazo emfutshane:
I-geotextile elukiweyo ye-filament luhlobo lwe-geomaterial enamandla aphezulu eyenziwe ngezinto zokwenziwa ezifana ne-polyester okanye i-polypropylene emva kokucutshungulwa. Ineempawu ezibonakalayo ezintle kakhulu ezifana nokumelana nokuxinana, ukumelana nokukrazuka kunye nokumelana nokubhoboza, kwaye ingasetyenziswa kulawulo lomhlaba, ukuthintela ukuvuza kwamanzi, ukuthintela ukugqwala kunye neminye imimandla.
Inkcazelo yeemveliso
I-geotextile elukiweyo ye-filament ludidi lwe-geotextile, yifayibha yokwenziwa yoshishino enamandla aphezulu njengoko izinto eziluhlaza, ngokuveliswa kwenkqubo yokuluka, luhlobo lwelaphu olusetyenziswa kakhulu kubunjineli bokwakha. Kwiminyaka yakutshanje, ngokukhawuleziswa kokwakhiwa kweziseko zophuhliso kulo lonke ilizwe, imfuno yee-geotextile elukiweyo ye-filament nayo iyanda, kwaye inamandla amakhulu emfuno yemarike. Ingakumbi kulawulo olukhulu lomlambo kunye notshintsho, ukwakhiwa kolondolozo lwamanzi, umgaqo omkhulu kunye nebhulorho, ukwakhiwa koololiwe, izibuko lesikhululo seenqwelomoya kunye nezinye iinkalo zobunjineli, ineendlela ezahlukeneyo zokusetyenziswa.
Inkcazo
Amandla okuqhekeka okuqhelekileyo kwi-MD (kN/m): 35, 50, 65,8 0, 100, 120, 140, 160, 180, 200, 250, ububanzi bungaphakathi kwe-6m.
Ipropati
1. Amandla aphezulu, ukuguquguquka okuphantsi.
2. Ukuqina: impahla ezinzileyo, engelula ukuyisombulula, ityibilika emoyeni kwaye ingagcina impahla yokuqala ixesha elide.
3. Ukulwa nokukhukuliseka: ukulwa ne-asidi, ukulwa ne-alkali, ukumelana nezinambuzane kunye nokungunda.
4. Ukuvuleka: inokulawula ubungakanani besihluzo ukugcina ukuvuleka okuthile.
Isicelo
Isetyenziswa kakhulu kumlambo, elunxwemeni, echwebeni, kwindlela enkulu, koololiwe, echwebeni, etoneleni, ebhulohweni nakwezinye iintlobo zobunjineli be-geotechnical. Ingahlangabezana nazo zonke iintlobo zeemfuno zeprojekthi ze-geotechnical ezifana nokuhluzwa, ukwahlula, ukuqinisa, ukhuseleko njalo njalo.
