Indlela yokubeka isendlalelo sokuvikela se-HDPE geomembrane ekwakhiweni kwe-anti-seepage?
Ukubekwa kwe-HDPE geomembrane kusebenzisa ukulandelana kwe-slope kuqala bese kuba phansi kwechibi. Uma ubeka ifilimu, ungayidonsi ngokuqinile, shiya umkhawulo othize wokucwila kwendawo kanye nokwelula. Amalunga avundlile akumele abe endaweni eyehlelayo futhi akumele abe ngaphansi kuka-1.5m ukusuka phansi komthambeka. Amajoyinti amade ezingxenye eziseduze akumele abe kulayini ovundlile ofanayo futhi azonyakaziswa ngaphezu kuka-1m ukusuka kwelinye. Ungadonsi noma uyidonse ngenkani i-geomembrane ngesikhathi sokuthutha ukuze ugweme izinto ezicijile ekuyibhobhozeni. Amapayipi omoya wesikhashana kufanele abekwe ngaphambili ngaphansi kolwelwesi ukuze kukhishwe umoya ngaphansi, kuqinisekiswe ukuthi i-geomembrane inamathele ngokuqinile kungqimba oluyisisekelo. Izisebenzi zokwakha kufanele zigqoke izicathulo zenjoloba ezinesoli ethambile noma izicathulo zendwangu phakathi nomsebenzi wokwakha, futhi zinake umthelela wesimo sezulu nezinga lokushisa kulwelwesi.

Izinyathelo ezithile zokwakha zimi kanje:

I-1) Ukusika i-geomembrane: Ukulinganisa kwangempela kwendawo yokubeka kufanele kwenziwe ukuze kutholwe izilinganiso ezinembile, bese kusikwa ngokuhambisana nobubanzi obukhethiwe nobude be-geomembrane ye-HDPE kanye nepulani yokubeka, kucatshangelwa ububanzi bokugqagqana bokushisela. Indawo emise okwefeni ekhoneni elingezansi lechibi kufanele isikwe ngokufanelekile ukuze kuqinisekiswe ukuthi zombili iziphetho ezingenhla nezingezansi zibambelele ngokuqinile.

I-2) Ukwelashwa okuthuthukisiwe kwemininingwane: Ngaphambi kokubeka i-geomembrane, amakhona angaphakathi nangaphandle, ama-deformation joints kanye neminye imininingwane kufanele ithuthukiswe kuqala. Uma kunesidingo, i-HDPE geomembrane enezingqimba ezimbili ingashiselwa.

3) Ukubeka i-slope: Isiqondiso sefilimu kufanele sihambisane ngokuyisisekelo nomugqa we-slope, futhi ifilimu kufanele ibe isicaba futhi iqonde ukugwema imibimbi nama-ripples. I-geomembrane kufanele imiswe phezulu echibini ukuze ingawi futhi ishelele phansi.

Isendlalelo esivikelayo emthambekeni siyi-geotextile engalukiwe, futhi isivinini sayo sokubeka kufanele sihambisane nesivinini sokubeka ifilimu ukugwema ukulimala komuntu ku-geotextile. Indlela yokubeka i-geotextile kufanele ifane neye-geomembrane. Izingcezu ezimbili ze-geotextile kufanele ziqondaniswe futhi zidlulelane, ngobubanzi obungaba ngu-75mm ngokwezidingo zokuklama. Kufanele zithungwe ndawonye kusetshenziswa umshini wokuthunga ophathwa ngesandla.

4) Ukubekwa phansi kwechibi: Beka i-HDPE geomembrane esisekelweni esiyisicaba, esibushelelezi futhi esinwebeka ngokusesilinganisweni, futhi sinamathele eduze kwendawo engaphezulu ukuze ugweme imibimbi nokunyakaza. Ama-geomembrane amabili kufanele aqondaniswe futhi adlulelane, abe nobubanzi obungaba ngu-100mm ngokwezidingo zokuklama. Indawo yokushisela kufanele igcinwe ihlanzekile.
