Iimpawu zeMveliso
| 1, Uhluzo |
| xa amanzi edlula kwi-fine-grained ukuya ku-coarse grained layer, i-Non-woven Geotextiles inokugcina amasuntswana amahle kakuhle.Njengaxa amanzi ephuma kumhlaba oyisanti ukuya kumjelo wegrabile esongelwe yiGeotextile. |
| 2, Ukwahlula |
| ukwahlula iileya ezimbini zomhlaba ezineempawu ezibonakalayo ezahlukileyo, ezinjengokwahlulwa kwegrabile yendlela kwizinto ezithambileyo ezisezantsi. |
| 3, Ukuhanjiswa kwamanzi |
| ukukhupha i-liquid okanye igesi kwi-plane yelaphu, ekhokelela ekukhutsheni okanye ekuphumeni komhlaba, njengomaleko we-gas vent kwi-cap yokulahla. |
| 4, Ukomelezwa |
| ukuphucula umthamo wokuthwala umthwalo wesakhiwo esithile somhlaba, njengokuqiniswa kodonga olugcinayo.5. ekhuselayoXa amanzi ehamba emhlabeni, uya kugxininisa ukusasazwa koxinzelelo ngokufanelekileyo, ukuhanjiswa okanye ukubola, kuthintela umhlaba ukuba ufumane isenzo samandla angaphandle kodwa ukutshatyalaliswa, umhlaba wokukhusela. 6. Ukuchasa ukugqobhoza Idityaniswe ne-geomembrane, i-composite waterproof kunye nezixhobo ezingenamanzi zidlala indima ekunqandeni ukugqobhoza. Amandla okuqina aphezulu, ukungena kakuhle, ukungena komoya, ukumelana nobushushu obuphezulu, ukuchasana nomkhenkce, ukuchasa ukuguga, ukuxhathisa umhlwa, ukungabikho kwenundu. I-geotextile engalukwanga ngenaliti sisixhobo se-geosynthetic esisetyenziswa kakhulu.Isetyenziswe ngokubanzi ekuqinisweni komgangatho womzila kaloliwe, umgangatho wendlela Ugcino, iholo yezemidlalo, ukukhuselwa kodonga, ukwahlukaniswa kolwakhiwo lwamanzi, itonela, unxweme oluselunxwemeni, ukugcinwa ngokutsha, ukukhuselwa kwendalo kunye nezinye iiprojekthi.

Iiparamitha zeMveliso
Isicelo kunye neNkonzo yasemva koThengiso
(1) Ukuqinisa ukufakwa komqolo kodonga olugcinayo okanye ukumisa ipleyiti yobuso yodonga olugcinayo.Yakha iindonga ezisongelweyo ezigcinayo okanye iiabutments.
(2) Ukuqinisa i-pavement eguquguqukayo, ukulungisa iintanda endleleni kunye nokuthintela iintanda ezikhanyayo kwindlela.
(3) Yandisa uzinzo lwethambeka legrabile kunye nomhlaba owomeleziweyo ukuthintela ukukhukuliseka komhlaba kunye nomonakalo womkhenkce kwiqondo lobushushu eliphantsi.
(4) Umaleko wokwahlula phakathi kwe-ballast kunye ne-roadbed okanye phakathi kwendlela kunye nomhlaba othambileyo.
5
(6) Umaleko wesihluzo seendawo eziphezulu zedama lokuqala lokugcina uthuthu okanye idama leentsalela zezimbiwa, kunye nomaleko wesihluzo senkqubo yokuhambisa amanzi kwindawo engasemva yodonga olugcinayo.
(7) Umaleko wesihluzo ojikeleze umbhobho wokuhambisa amanzi okanye umsele wokuhambisa igrabile.
(8) Izihluzi zemithombo yamanzi, imithombo yokukhulula okanye imibhobho yoxinzelelo lwe-oblique kubunjineli be-hydraulic.
9
(10) Umjelo othe nkqo okanye othe tyaba phakathi kwedama lomhlaba, ongcwatywe emhlabeni ukuze uchithe uxinzelelo lwamanzi epore.
(11) Ukuhanjiswa kwamanzi ngasemva kwegeomembrane engangenwayo okanye phantsi kokhuselo lwekonkrithi kumadama omhlaba okanye eludongeni.
Ulwakhiwo loKwakha
Ufakelo lweGeotextile olungalukwanga :
1, ngokufakela okuqengqelekayo ngesandla, umphezulu we-filament ongalukwanga we-geotextile kufuneka uthotywe, kunye nesibonelelo esifanelekileyo soguquko.
2. Ufakelo lwe-Filament Non olukiweyo I-Geotextile okanye i-fiber emfutshane engekho i-geotextile idla ngokuthatha iindlela ezininzi ze-lap joint, i-suture kunye ne-welding.Ububanzi be-suture kunye ne-welding ngokubanzi ngaphezu kwe-0.1m, kwaye ububanzi be-lap ngokubanzi bungaphezulu kwe-0.2m.I-Geotextiles ezinokuvezwa ixesha elide kufuneka zidibanise okanye zithungwe kunye.
3. Umthungo weGeotextile:
Yonke imithungo mayiqhubeke (umzekelo, ukuthungwa kwamanqaku akuvumelekanga).I-Geotextile engalukwanga kufuneka idibane ubuncinane nge-150mm phambi kokudibana.Umgama omncinci wokuthunga ukusuka kumda (umda ocacileyo wezinto eziphathekayo) kufuneka ube ubuncinane ubuncinane be-25mm.
I-Filament Non loven Geotextile joints eziye zathungwa kakhulu ziquka umgca o-1 wendlela yokuthunga intambo yokutshixa.Umsonto osetyenziselwa i-suture uya kuba yinto ye-resin kunye ne-tension encinci engaphezu kwe-60N kwaye iya kuba nokuchasana okufanayo okanye okukhulu kwimichiza yokubola kunye nemitha ye-ultraviolet njenge-geotextile.
Nakuphi na "ukuvuza kwenaliti" kwi-geotextile kufuneka iphinde ithungwe apho ichaphazeleke khona.
Amanyathelo afanelekileyo kufuneka athathwe ukukhusela umhlaba, i-particle okanye into yangaphandle ekungeneni kwi-geotextile layer emva kokufakwa.
Umdibaniso welaphu unokwahlulwa ube yindalo edibeneyo, i-seam joint okanye i-welding ngokuhambelana ne-topography kunye nokusebenza komsebenzi.
4. Ekwakhiweni, i-geomembrane ye-HDPE ngaphezu kwe-geotextile iya kugoba ngokwemvelo, kunye ne-HDPE geomembrane kumaleko angaphezulu, i-filament non-woven geotextile iya kuthungwa okanye idityaniswe ngumoya oshushu.I-welding air eshushu yindlela yokudibanisa ekhethiweyo ye-filament geotextile, oko kukuthi, ukudityaniswa kwamaqhekeza amabini kunye nompu womoya oshushu kushushu ngokukhawuleza kwiqondo lokushisa eliphezulu, ukuze inxalenye yalo ifikelele kwisimo sokunyibilika, kwaye ngokukhawuleza usebenzise amandla athile angaphandle. ukuyenza idityaniswe ngokuqinileyo kunye.Kwimozulu emanzi (imvula kunye nekhephu) ayikwazi ukudibanisa ukunamathela okushushu, i-geotextile kufuneka ithathe enye indlela indlela yokudibanisa i-suture, oko kukuthi, umatshini wokuthunga okhethekileyo wokudibanisa kabini, kunye nokusetyenziswa kwe-anti-chemical ultraviolet suture line.
Ububanzi obuncinane kwi-suture yi-10cm, ububanzi obuncinane kwi-natural lap yi-20cm, kunye nobubanzi obuncinane kwi-welding yomoya oshushu yi-20cm.
5. Ukudibanisa i-seam, umgangatho ofanayo kunye ne-geotextile kufuneka usetyenziswe, kwaye umgca we-suture kufuneka ube nezinto ezinokumelana okunamandla kumonakalo weekhemikhali kunye ne-ultraviolet irradiation.
6. I-Geomembrane iya kubekwa emva kokubekwa kwe-geotextile ize ivunywe yinjineli eyongamela kwindawo leyo.
Iimfuno ezisisiseko zokubeka i-Filament engalukwanga ngeGeotextile:
1. Umdibaniso uya kunqumla umgca wokuthambeka;Apho kukho ibhalansi okanye uxinzelelo olunokubakho ngonyawo lwethambeka, umgama othe tyaba odibeneyo uya kuba mkhulu kune-1.5m.
2. Kwi-slope, qinisa enye isiphelo se-Filament Non woven Geotextile, kwaye emva koko ubeke izinto zokuqengqeleka kwi-slope ukuqinisekisa ukuba i-geotextile ihlala iqinile.
3. Yonke i-Filament Non woven Geotextile iya kucinezelwa ngeengxowa zesanti, eziya kuthi zisetyenziswe ngexesha lokubeka kwaye zigcinwe kumaleko aphezulu wezinto.
