Indlela yokubeka i-HDPE geomembrane umaleko wokukhusela kwi-anti-seepage yokwakha?
Ukubekwa kwe-HDPE geomembrane kwamkela ulandelelwano lwethambeka kuqala kwaye emva koko ngezantsi kwepool. Xa ubeka ifilimu, ungayitsali ngokukhawuleza, ushiye umda othile wokucwina kwendawo kunye nokwelula. Izihlanganisi ezithe tyaba aziyi kuba kumphezulu wethambeka kwaye aziyi kuba ngaphantsi kwe-1.5m ukusuka kunyawo lwethambeka. Iijoyinti zelongitudinal zamacandelo ameleneyo aziyi kuba kumgca othe tye kwaye ziya kugxagxanyiswa ngaphezu kwe-1m ukusuka kwelinye. Musa ukutsala okanye ukutsala ngenkani i-geomembrane ngexesha lothutho ukunqanda izinto ezibukhali ekuyigqobhozeni. Imibhobho yomoya yesikhashana kufuneka ibekwe ngaphambili phantsi kwe-membrane ukuphelisa umoya ngaphantsi, ukuqinisekisa ukuba i-geomembrane inamathele ngokuqinileyo kwinqanaba lesiseko. Abasebenzi bokwakha kufuneka banxibe izihlangu zerabha ezithambileyo okanye izihlangu zelaphu ngexesha lomsebenzi wokwakha, kwaye banikele ingqalelo kwimpembelelo yemozulu kunye nobushushu kwinwebu.

Amanyathelo okwakha athile angoluhlobo lulandelayo:

I-1) Ukusika i-geomembrane: Umlinganiselo wangempela wendawo yokubeka kufuneka uqhutywe ukuze ufumane imilinganiselo echanekileyo, kwaye emva koko usike ngokuhambelana nobubanzi obukhethiweyo kunye nobude be-geomembrane ye-HDPE kunye nesicwangciso sokubeka, ngokuqwalasela ububanzi be-overlap ye-welding. Indawo emile okwefeni kwikona esezantsi yedama kufuneka isikwe ngokufanelekileyo ukuqinisekisa ukuba zombini iziphelo eziphezulu nezisezantsi zibambelele ngokuqinileyo.

I-2) Unyango lokuphucula iinkcukacha: Ngaphambi kokubeka i-geomembrane, iikona zangaphakathi nangaphandle, i-deformation joints kunye nezinye iinkcukacha kufuneka ziphuculwe kuqala. Ukuba kuyimfuneko, i-HDPE i-geomembrane ene-double-layer inokudityaniswa.

I-3) Ukubekwa kwe-Slope: Isalathiso sefilimu kufuneka sihambelane ngokusisiseko nomgca we-slope, kwaye ifilimu kufuneka ibe flat kwaye iqonde ukuphepha imibimbi kunye ne-ripples. I-geomembrane kufuneka igxininiswe phezulu kwedama ukunqanda ukuba ingawi kunye nokutyibilika ukuya ezantsi.

Umaleko okhuselayo kwi-slope yi-geotextile engeyiyo ephothiweyo, kwaye isantya sayo sokubeka kufuneka sihambelane nesantya sokubeka ifilimu ukuphepha umonakalo womntu kwi-geotextile. Indlela yokubeka i-geotextile kufuneka ifane ne-geomembrane. Iziqwenga ezimbini ze-geotextile kufuneka zihambelane kwaye zigqitywe, kunye nobubanzi obumalunga ne-75mm ngokweemfuno zoyilo. Kufuneka zithungwe kunye kusetyenziswa umatshini wokuthunga ophathwa ngesandla.

I-4) Ukubekwa ezantsi kwe-pool: Beka i-HDPE geomembrane kwisiseko esisicaba, esithambileyo kunye ne-elastic ephakathi, kwaye unamathele ngokusondeleyo kumphezulu womhlaba ukuze ugweme imibimbi kunye ne-ripples. I-geomembranes ezimbini kufuneka zihambelane kwaye zigqithe, kunye nobubanzi obumalunga ne-100mm ngokweemfuno zoyilo. Indawo ye-welding kufuneka igcinwe icocekile.
