Kusankhidwa kwa zinthu zotsutsana ndi seepage, anti-seepage membrane ndi chinthu chofunika kwambiri pamadzi opangira nyanja, kotero choyamba, ndikofunika kusankha geomembrane ya khalidwe labwino, komanso kuganizira za kumangidwe. Kusankhidwa kwa geomembrane kuyenera kulabadira mfundo zotsatirazi:
Pakupenta, kuwotcherera, makamaka kuwotcherera pamtanda, kuyenera kuchepetsedwa kuti kuchepetsa kutayikira komwe kungathe.
Kuonjezera apo, kuya kwa madzi a m'nyanja yochita kupanga nthawi zambiri ndi mamita 5, choncho m'pofunika kuonetsetsa kuti mphamvu ya geomembrane ndi yokwanira, ndipo maziko a nyanja yokumba ndi ofunika kwambiri, pamene mazikowo amapunduka kwambiri. , geomembrane idzanyamula katundu wosiyanasiyana.
Zomangamanga:
1. Malinga ndi zojambulazo, fukuni mawonekedwe a nyanja, kuphatikizapo kuya kwa nyanja ndi malo otsetsereka; kwezani m'munsi mwa nyanjayo ndi kukokera nthaka ya maziko kuti mupange nyanjayo; mawonekedwe ozungulira amatenga khoma lamtunda wa 180 kapena 240 mm, ndipo khomalo limakutidwa ndi nembanemba yotsutsa-seepage; Konzani ngalande zakhungu ndikugwira bwino, kusefukira bwino;
2. Pansi pake pali gawo lalikulu la 150-200 wandiweyani wa miyala. Ntchito ya miyala ya miyala ndi kutembenuza madzi a pansi pa nthaka ndikuletsa madzi apansi kuti asatulutse nsanjika yosasunthika pamene nyanjayo yatsanulidwa. Mwala ufa wosanjikiza kapena sing'anga-coarse mchenga wosanjikiza 80mm wandiweyani mosanjikiza maziko;
3. Yalani magalamu 100 a nsalu zosalukidwa ngati gawo lodzipatula; ikani nembanemba yosakwanira 1mm; ikani magalamu 100 a nsalu yopanda nsalu ngati gawo lodzipatula; pangani 100 mm wandiweyani simenti ufa wosanjikiza wosanjikiza, ndiyeno ikani wosanjikiza wa matope 30 mm wandiweyani, ndipo wosanjikiza wosanjikiza umafanana ndi 3 * 3m kugawa khoma mfundo (kapena 60 wandiweyani njerwa wofiira wosanjikiza imayikidwa pa 60 wandiweyani. ufa wa mwala wosanjikiza, wosanjikiza matope 25-wokhuthala; façade yozungulira imatenga khoma lamkati la njerwa la 180mm, lomwe ndi khoma loteteza la nembanemba ya anti-seepage yakunja kwakunja;
Ma geomembranes ambiri amagwiritsidwa ntchito popanga ngalande, ngati pali njira, ndiye kuti ngalande imatha kupezeka. Nembanemba yosasunthika sichifukwa chachikulu cha kugwa kwa polojekitiyi. Chinsinsi cha nkhawa yathu ndi kusintha kwa dothi komwe kumachitika chifukwa cha madzi mu geomembrane, ndipo chinsinsi cha nkhawa yathu ndi kusintha kwa nthaka chifukwa cha madzi.
M’madera ambiri, nyengo yachilimwe imakhala yotentha kwambiri ndipo madzi amatuluka nthunzi kwambiri. Ma geomembranes atenganso njira zambiri zothana ndi kusowa kwa madzi m’madera ouma, omwe ndi opanda madzi kwambiri. Geomembrane ndi zinthu zomwe sizingalowerere bwino ndipo zitha kugwiritsidwa ntchito m'malo owuma. Katunduyu amagwiritsidwanso ntchito kwambiri pantchito zamitengo m'madera omwe mulibe madzi.
Nthawi yomweyo, kukana kwa dzimbiri kumachulukitsidwa pakuchita kwazinthu, ndipo kukana kwake kwa dzimbiri kumakhala kolimba kwambiri. Ikhoza kutsimikizira moyo wautumiki. Mankhwalawa ndi othandiza kwambiri m'madera omwe alibe madzi kwambiri.
