Ukusetyenziswa kweGeomembranes
Kwindawo yokusingqongileyo yeendawo zokulahla inkunkuma: Iinwebu ezihlanganisiweyo ze-geotextile zingasetyenziswa kwiiprojekthi ezifana ne-leachate lagoons namanzi emvula kunye nogutyulo olugutyungelwayo olugquma inwebu zeendawo zokulahla inkunkuma.
Isixhobo se-anti-seepage geomembrane yokulahla inkunkuma: i-HDPE ephezulu kakhulu # geomembrane #, imathiriyeli yepolymer, amandla aphezulu, ubomi benkonzo ende, kunye nobude obuphezulu.
Ukucaciswa kwe-polyethylene geomembrane yoxinaniso oluphezulu: Ububanzi buqhele ukuba yi-6m, kwaye ubukhulu bungenziwa ngokwezifiso phakathi kwe-0.1mm kunye ne-3.0mm.
Kufuneka wazi injongo ye-geomembrane efunekayo kuqala. Iindidi ezahlukeneyo ze-geomembrane zineepropati ezahlukeneyo kunye neempawu, ezifana nokungangeni kwamanzi, ukuphefumla, ukuchasana nokubanda, ukuguga, njl. Kuphela emva kokuba injongo inqunywe unokukhetha imveliso efanelekileyo.
IiGeomembranes zihlelwa ngokwala manqanaba omgangatho alandelayo ngokusekwe kwizinto ezahlukeneyo ezisetyenziswayo:
I-membrane esemgangathweni ye-anti-seepage, inwebu endala yesizwe echasene ne-seepage (GB/T 17643-1998);
I-membrane entsha yesizwe echasene ne-seepage (GB/T17643-2011) GH-1 kunye ne-GH-2S zihambelana nokusingqongileyo, ngelixa i-membrane yolwakhiwo lwasezidolophini i-anti-seepage membrane (CJ/T 234-2006) inezalathi zobugcisa ezifanayo kumgangatho waseMelika. GM-13;
Uxinaniso oluphezulu lwe-polyethylene geomembrane, njengesixhobo esichasene ne-seepage geosynthetic, ibalulekile kukhuseleko lwendalo esingqongileyo kunye nokwahlulwa kokuchasana nokuphuma kwamanzi. Kwezi projekthi zichasene nokusingqongileyo, zithintela amanzi amdaka kunye nenkunkuma evuzayo ukuba ingangeni kumandlalo wamanzi aphantsi komhlaba kwaye iwangcolise. Ingasetyenziselwa ukubekwa kweeleya ezingenamanzi ukuthintela ukungena kwamanzi.
Amanyathelo ofakelo lwe-geomembrane:
Ukulungiselela ukudityaniswa kwe-polyethylene geomembrane ephezulu yoxinaniso lwendawo yokulahla inkunkuma: Ngaphambi kokuqala ukufakwa kwe-geomembrane, kuyimfuneko ukucoca indawo yokwakha ukuze kuqinisekiswe indawo egudileyo ngaphandle kweeprotrusions okanye izinto ezibukhali ukuphepha ukulimaza i-geomembrane.
Amanyathelo okubeka i-membrane ye-geotextile: Beka i-membrane ye-geotextile kwindawo yokwakha, kunye nemiphetho edibeneyo malunga ne-15cm, kwaye ulungiselele ukudibanisa nomatshini we-welding welding eshushu.
