I-geotextile emhlophe ye-100% ye-polyester engalukwanga yokwakhiwa kwedama lendlela
Inkcazo emfutshane:
Ii-geotextile ezingalukwanga zinezibonelelo ezininzi, ezinje ngokuphefumla umoya, ukuhluza, ukugquma, ukufunxa amanzi, ukungangeni manzi, ukurhoxa, ukuvakala kakuhle, ukuthambile, ukukhanya, ukuthamba, ukubuyiswa kwakhona, akukho ndlela yelaphu, imveliso ephezulu, isantya semveliso kunye namaxabiso aphantsi. Ukongeza, ikwanayo namandla aphezulu okutsalwa kunye nokumelana nokukrazuka, ukutsalwa kwamanzi ngokuthe nkqo nangokuthe tye, ukuhlukaniswa, ukuzinza, ukuqinisa kunye neminye imisebenzi, kunye nokusebenza kakuhle kokungena kunye nokuhluza.
Inkcazelo yeemveliso
Ii-geotextile ezingalukwanga zizinto ezisetyenziswa kwi-geosynthetic ezingena emanzini ezenziwe ngeefayibha zokwenziwa ngokufaka inaliti okanye ukuluka. Zinokucoca okugqwesileyo, ukuzohlula, ukuqinisa kunye nokukhusela, ngelixa zinamandla aphezulu okutsalwa, ukukwazi ukungena kakuhle, ukumelana nobushushu obuphezulu, ukumelana nokubanda, ukumelana nokwaluphala, ukumelana nokugqwala. Ii-geotextile ezingalukwanga zisetyenziswa kakhulu kwiiprojekthi ezininzi, ezinje ngeendlela, oololiwe, ii-embankments, ii-earth-rock DAMS, izikhululo zeenqwelo-moya, amabala emidlalo, njl.njl., ukuqinisa iziseko ezibuthathaka, ngelixa zidlala indima yokuzohlula kunye nokuhluza. Ukongeza, ikwafanelekile ukuqinisa kwi-backfill yeendonga zokugcina, okanye ukuqinisa iiphaneli zeendonga zokugcina, kunye nokwakha iindonga zokugcina ezibhityileyo okanye ii-abutments.
Uphawu
1. Amandla aphezulu: phantsi kweenkcukacha zobunzima obufanayo begram, amandla okutsalwa kwee-geotextile ezinde zesilika ezisontiweyo ezingenanto yokwaluka kuzo zonke iindlela aphezulu kunalawo amanye ama-nonwoven angenanto yokwaluka, kwaye anamandla okutsalwa aphezulu.
2. Ukusebenza kakuhle kokuqhekeka: Le geotextile isebenza kakuhle kokuqhekeka, inokugcina ukusebenza okuzinzileyo xa isetyenziswa ixesha elide, kwaye ayilula ukuyiguqula.
3. Ukumelana nokugqwala okunamandla, ukumelana nokwaluphala kunye nokumelana nobushushu: i-geotextile ende ene-spunbonded needled nonwoven geotextile inokumelana nokugqwala okugqwesileyo, ukumelana nokwaluphala kunye nokumelana nobushushu, kwaye ingasetyenziswa ixesha elide kwindawo enzima ngaphandle komonakalo.
4. Ukusebenza kakuhle kokugcinwa kwamanzi: iimbobo zayo zesakhiwo zinokulawulwa ngokufanelekileyo ukuze kufezekiswe ukuvuleka okuthile, okufanelekileyo kwiiprojekthi ezifuna ukulawula ukuhamba kwamanzi.
5. Ukhuseleko lokusingqongileyo kunye nokuqina, ukonga kunye nokusebenza kakuhle: xa kuthelekiswa nezixhobo zemveli, i-geotextile ende ebotshelelweyo yesilika ende inobuhlobo nokusingqongileyo, inokuphinda isetyenziswe kwaye isetyenziswe, inciphise umthwalo wokusingqongileyo, kwaye ihlala ixesha elide, ukubonakaliswa kwayo ixesha elide kusenokugcina ukusebenza okuzinzileyo, kunciphisa kakhulu iindleko zokulungisa.
6. Ulwakhiwo olulula: ulwakhiwo olulula, aludingi teknoloji kunye nezixhobo ezintsonkothileyo, longa abasebenzi kunye nezixhobo eziphathekayo, zilungele iiprojekthi ezikhawulezayo.
Isicelo
Isetyenziswa kwindawo yendlela enkulu, kaloliwe, edamini, elunxwemeni lolwandle ukuze kusetyenziswe amandla okulawula, kuhluzwe, kuhluzwe kwaye kukhutshwe amanzi, ingakumbi kwiindawo ezinetyuwa kunye nendawo yokungcwaba inkunkuma. Isetyenziswa kakhulu ekuhluzweni, ekuqinisweni nasekuhluzweni.
