Ii-geotextileinesiphumo esibalulekileyo sokwahlukanisa, esinokuthintela ngempumelelo umphezulu wendlela ukuba ungawi kwaye ube nodaka, kwaye inesiphumo sokuqinisa kunye nesiphumo sokusasazwa koxinzelelo, okuphucula kakhulu uzinzo lwendlela ethambileyo emanzi.
Ii-geotextile zibonakala ngamandla aphezulu, ukumelana nokugqwala kunye nokungena kwamanzi kakuhle. Imisebenzi yazo ikakhulu kukucoca, ukwahlulahlula, ukuqinisa, ukukhusela, njl.
Abavelisi be-geotextile baseTshayina
Ulwahlulo lwee-geotextiles:
1. Izinto ezahlukeneyo zokwenza imveliso: zingahlulwa zibe yi-polyester geotextile, i-polypropylene geotextile, njl.njl.;
2, umahluko phakathi kwezalathisi: zingahlulwa zibe yi-geotextile yesilika emfutshane, i-filament geotextile, ilaphu le-geotextile, ilaphu elilukiweyo, ilaphu elilukiweyo, njl.njl.;
3. Iinkqubo ezahlukeneyo zemveliso zingahlulwa zibe zii-geotextile ezingalukwanga ezibhobozwe ngenaliti kunye nee-geotextile ezilukiweyo;
I-geotextile, i-polyester staple fiber needled geotextile sisixhobo se-geosynthetic esisetyenziswa kakhulu. Sisetyenziswa kakhulu ekuqiniseni i-subgrade kaloliwe, ukugcinwa kwendlela, ukukhuselwa kweeholo zemidlalo, amadama, ukwahlulwa kwezakhiwo ze-hydraulic, ukugquma, ukugquma elunxwemeni, ii-cofferdams, ukukhuselwa kwendalo kunye nezinye iiprojekthi.
Indlela yokubeka i-geotextile:
Sebenzisa i-artificial rolling, umphezulu welaphu kufuneka ube tyaba, kwaye i-deformation allowance ishiywe njengoko kufanelekile.
Ukufakelwa kwe-filament okanye ii-geotextiles ezimfutshane kudla ngokwenziwa ngama-lap joints, ukuthunga kunye nokuwelda.
Ububanzi bokuthunga kunye nokuwelda buhlala bungaphezulu, kwaye ububanzi bokugqithana buhlala bungaphezulu. Ii-geotextile ezinokuvezwa ixesha elide kufuneka zifakwe okanye zithungwe.
Ukuthungwa kwee-geotextile: Zonke izithungo kufuneka zenziwe rhoqo (umzekelo, ukuthungwa kweengongoma akuvumelekanga). Ii-geotextile mazigqume ubuncinane i-150 mm ngaphambi kokuba zigqume. Umgama omncinci wokuthungwa ubuncinci yi-25 mm ukusuka kwi-selvedge (umphetho ovezweyo wezinto).
Umsebenzi womaleko wesihluzo: Ilaphu le-geotextile linomoya ofanelekileyo wokungena kwegesi, linokugcina umhlaba, isanti etyheli, ilitye elincinci kwaye lihluze ukuhamba kwamanzi, kwaye ligcine uzinzo lobunjineli bomhlaba namatye.
Ukukhupha amanzi:Ilaphu le-geotextile elingalukwangaineempawu ezilungileyo zokuhambisa amanzi. Ingasetyenziselwa ukwenza imijelo yokukhupha amanzi ngaphakathi komhlaba kwaye ikhuphe amanzi angaphezulu ngaphakathi kwesakhiwo somhlaba.
Kukho ezinye izizathu ezininzi zokusetyenziswa kwee-geotextiles kwindlela yokuhamba ngeenyawo. Umzekelo, ubukhulu bemveliso bufanelekile, kwaye kulula ukuyidibanisa ne-asphalt pavement. Xa idityaniswe neoyile yomaleko wokuncamathelisa, yenza umaleko owahlulayo, onemisebenzi yokuthintela amanzi kunye nokugcina ubushushu. Umphezulu urhabaxa kwaye akulula ukuwutyibiliza.
Xa ubeka, umphezulu uphathwa ngokukodwa kwaye icala elirhabaxa lijonge phezulu, okonyusa i-friction coefficient, okonyusa i-friction coefficient, okonyusa amandla okubopha komaleko womphezulu, oko kuthintela ivili ukuba lingasongwa kwaye lonakale ngexesha lokwakhiwa, kunye nokucinezela imoto kunye ne-paver elaphini. Ingxaki yokutyibilika kula macala yenza ezi geotextile ezingalukwanga zibe luncedo oluhle ekugcinweni kwendlela.
Abavelisi be-geotextile baseTshayinauthe xa kusenziwa ii-geotextile, ii-geotextile ezikwi-geomembrane zidibene ngokwendalo, kwaye ii-geotextile ezikwi-geomembrane zithungiwe okanye zifakwe umoya oshushu.
Ukuwelda komoya oshushu yindlela yokudibanisa ii-geotextiles ze-filament, oko kukuthi, uqhagamshelo lweziqwenga ezibini zelaphu nomoya oshushu lufudunyezwa ngoko nangoko kubushushu obuphezulu ukuze lunyibilikise inxalenye yemeko, kwaye ngoko nangoko kusetyenziswe amandla athile angaphandle ukuzibophelela ngokuqinileyo.
Kwimeko yemozulu emanzi (enemvula nekhephu), uqhagamshelo olunamathelayo olushushu alunakwenzeka. I-geotextile kufuneka isebenzise enye indlela, indlela yoqhagamshelo lwe-suture, oko kukuthi, uqhagamshelo lwe-suture olunemisonto emibini kunye nomatshini wokuthunga okhethekileyo, kunye ne-suture ye-ultraviolet engamelani neekhemikhali iyasetyenziswa.
I-filament spunbonded needle-punched nonwoven geotextile yenziwe ngeetships zepolyester, ezinyibilikiswayo kwaye zenziwe iplastiki ngobushushu obuphezulu, zifakwe kwinethi, kwaye zilungiswe ngokubethelwa ngenaliti.
I-geotextile yaseTshayina
Abavelisi be-geotextile abathintela ukuvuza kwamanzi eTshayina-Jin Haochengamalaphu angalukwangabathembekile, wamkelekile iingcebiso zakho!
