I-geogrid yeplastiki eyoluliweyo ngaxeshanye
Inkcazo emfutshane:
- I-geogrid yeplastiki eyoluliweyo ngokukodwa luhlobo lwezinto ze-geosynthetic. Isebenzisa ii-polymers eziphezulu (ezifana ne-polypropylene okanye i-polyethylene ephezulu) njengezinto eziphambili kwaye yongeza i-anti-ultraviolet, anti-aging kunye nezinye izongezo. Iqala ngokukhutshwa kwipleyiti encinci, emva koko iminatha eqhelekileyo yemingxunya ibethelwa kwipleyiti encinci, kwaye ekugqibeleni yolulwe ngobude. Ngexesha lenkqubo yolulwe, imixokelelwane ye-molecular ye-polymer ephezulu ijongwa kwakhona ukusuka kwimeko yokuqala edibeneyo, yenza isakhiwo esidibeneyo esifana ne-oval-shaped-like-shared kunye nama-node anamandla aphezulu.

Iimpawu zokusebenza
- Amandla Aphezulu Nokuqina Okuphezulu: Amandla okutsalwa anokufikelela kwi-100 - 200MPa, kufutshane nenqanaba lentsimbi yekhabhoni ephantsi. Inamandla aphezulu okutsalwa nokuqina, okunokusasaza ngempumelelo nokudlulisa uxinzelelo emhlabeni kwaye kuphucule amandla okuthwala kunye nokuzinza kobunzima bomhlaba.
- Ukumelana Okugqwesileyo Kokuqhekeka: Phantsi kwesenzo somthwalo oqhubekayo wexesha elide, ukuthambekela kokuguquguquka (ukuqhekeka) kuncinci kakhulu, kwaye amandla okuxhathisa okuqhekeka angcono kakhulu kunezinye izinto zejogridi zezinye izinto, nto leyo edlala indima ebalulekileyo ekwandiseni ubomi benkonzo yeprojekthi.
- Ukumelana Nokugqwala Nokuxhathisa Ukwaluphala: Ngenxa yokusetyenziswa kwezinto zepolymer ezineemolekyuli ezininzi, izinzile kakuhle kwiikhemikhali kwaye ixhathisa ukugqwala. Ingasetyenziswa ixesha elide phantsi komhlaba onzima kunye neemeko zemozulu ngaphandle kokuguga okanye ukuqhekeka lula, nto leyo enokwandisa ubomi benkonzo yeprojekthi.
- Ulwakhiwo Olulula kunye neendleko - ukusebenza kakuhle: Lulula - ubunzima, kulula ukuluthutha, ukulusika nokulubeka, kwaye lunesiphumo esihle sokululungisa, nto leyo enokunciphisa iindleko zokwakha. Kwangaxeshanye, lusebenza kakuhle ekudibaniseni nomhlaba okanye ezinye izixhobo zokwakha kwaye kulula ukuludibanisa nezakhiwo ezahlukeneyo zobunjineli bokwakha ukuphucula ukusebenza kunye nokuzinza kweprojekthi iyonke.
- Ukumelana Okuhle NeeNyikima: Isakhiwo esiqinileyo sokugcina umhlaba sisakhiwo esiguquguqukayo esinokuzivumelanisa nokuguquguquka okuncinci kwesiseko kwaye sifumane amandla eenyikima ngempumelelo. Sisebenza kakuhle kwiinyikima kangangokuba izakhiwo eziqinileyo azinakulingana nazo.
Iindawo zoSetyenziso
- Ukuqinisa i-Subgrade: Ingaphucula ngokukhawuleza amandla okuthwala isiseko kwaye ilawule uphuhliso lweendawo zokuhlala. Inefuthe elithintela ecaleni kwisiseko sendlela, isasaze umthwalo kwisiseko esibanzi, inciphisa ubukhulu besiseko, inciphisa iindleko zeprojekthi kwaye yandise ubomi benkonzo yendlela.
- Ukuqinisa Indlela Yokuhamba Ngasecaleni: Ibekwe ezantsi komaleko wendlela ye-asphalt okanye yesamente, inokunciphisa ubunzulu be-rut, yandise ubomi bokulwa nokudinwa kwendlela, kwaye inciphise nobukhulu bendlela ye-asphalt okanye yesamente, ifezekisa injongo yokonga iindleko.
- Ukuqinisa udonga olugcina idama kunye nodonga olugcina amanzi: Ingasetyenziselwa ukuqinisa amathambeka eengxangxasi kunye neendonga ezigcina amanzi, ukunciphisa inani lokuzalisa ngaphezulu ngexesha lokuzalisa ingxangxasi, ukwenza umphetho wegxalaba ube lula ukuwucutha, ukunciphisa umngcipheko wokuwa kwengxangxasi kamva kunye nokungazinzi, ukunciphisa indawo ehlalwayo, ukwandisa ubomi benkonzo kunye nokunciphisa iindleko.
- Ukukhuselwa kweMigodi yoMlambo noLwandle: Xa yenziwe ibe zii-gabions kwaye isetyenziswa kunye nee-geogrids, inokuthintela ukuba i-embankment ingagutyungelwa ngamanzi olwandle ize ibangele ukudilika. Ukuvuleka kwee-gabions kunokucothisa impembelelo yamaza kwaye kwandise ubomi be-embankment, konga abasebenzi kunye nezixhobo zezinto kwaye kunciphise ixesha lokwakhiwa.
- Unyango lweLaptured: Isetyenziswa kunye nezinye izinto ze-geosynthetic.
