Geomembrane yophatikizika imatenthedwa ndi infuraredi yotalikirana mu uvuni kumbali imodzi kapena mbali zonse ziwiri za nembanemba, ndipo geotextile ndi geomembrane zimapanikizidwa ndi chowongolera kuti apange geomembrane yophatikiza.Palinso njira yopangira geomembrane yophatikizika.Maonekedwe ake ndi nsalu imodzi ndi filimu imodzi, nsalu ziwiri ndi filimu imodzi, mafilimu awiri ndi nsalu imodzi, nsalu zitatu ndi mafilimu awiri, ndi zina zotero.
Mawonekedwe
Geotextile imagwiritsidwa ntchito ngati gawo loteteza la geomembrane kuteteza wosanjikiza wosanjikiza kuti asawonongeke.Pofuna kuchepetsa ma radiation a ultraviolet ndikuwonjezera kukana kukalamba, njira yokwiriridwa imagwiritsidwa ntchito pakuyala.
1. M'lifupi mamita 2, mamita 3, mamita 4, mamita 6 ndi mamita 8 ndi othandiza kwambiri;
2. High puncture kukana ndi mkulu mikangano coefficient;
3. Kukana kukalamba kwabwino, kutengera kutentha kosiyanasiyana kozungulira;
4. Kuchita bwino kwambiri kwa anti-drainage;
5. Yogwiritsidwa ntchito posungira madzi, mankhwala, zomangamanga, zoyendera, zapansi panthaka, ngalande, kutaya zinyalala ndi ntchito zina.
Grassroots processing
1) Chigawo chapansi chomwe geomembrane chophatikizika chayikidwa chiyenera kukhala chathyathyathya, ndipo kusiyana kwautali wapaderalo sikuyenera kupitirira 50mm.Chotsani mizu yamitengo, udzu ndi zinthu zolimba kuti mupewe kuwonongeka kwa gulu la geomembrane.
Kuyika kwa zinthu zophatikizika za geomembrane
1) Choyamba, fufuzani ngati zinthuzo zawonongeka kapena ayi.
2) Geomembrane yophatikizika iyenera kuyikidwa molingana ndi mphamvu yake yayikulu, ndipo nthawi yomweyo, sayenera kukokedwa mwamphamvu kwambiri, ndipo kuchuluka kwa kukulitsa ndi kutsika kuyenera kusungidwa kuti zigwirizane ndi kusinthika kwa matrix..
3) Poika, iyenera kuimitsidwa pamanja, popanda makwinya, ndi pafupi ndi gawo lapansi.Iyenera kupangidwa nthawi iliyonse ndi sitolo kuti isatengedwe ndi mphepo.Kumanga sikungathe kuchitidwa pamene pali madzi oima kapena mvula, ndipo bentonite yomwe imayikidwa pa tsiku iyenera kuphimbidwa ndi backfill.
4) Pamene geomembrane yophatikizika imayikidwa, payenera kukhala malire pamapeto onse awiri.Mphepete mwa nyanja siidzakhala yosachepera 1000mm kumapeto kulikonse, ndipo idzakhazikitsidwa malinga ndi zofunikira za mapangidwe.
5) M'lifupi mwake filimu ya PE ndi nsalu ya PET yopanda zomatira (ie, kukana m'mphepete) zimasungidwa kumbali zonse za geomembrane yophatikizika.Poika, malangizo a gawo lililonse la geomembrane yophatikizika ayenera kusinthidwa kuti athandizire magawo awiri a geomembrane.kuwotcherera.
6) Kwa geomembrane yopangidwa ndi anaika, sipayenera kukhala mafuta, madzi, fumbi, etc. pa m'mphepete mfundo.
7) Musanayambe kuwotcherera, sinthani filimu imodzi ya PE pa mbali ziwiri za msoko kuti igwirizane ndi m'lifupi mwake.M'lifupi mwake nthawi zambiri ndi 6-8cm ndipo ndi yosalala komanso yopanda makwinya oyera.
kuwotcherera;
The gulu geomembrane ndi welded pogwiritsa ntchito makina owotcherera awiri njanji, ndi pamwamba PE filimu yolumikizidwa ndi kutentha mankhwala kutentha kusungunula pamwamba, ndiyeno anaphatikizana mu thupi limodzi ndi kukakamizidwa.
1) kuwotcherera mkanda lap m'lifupi: 80 ~ 100mm;makwinya zachilengedwe pa ndege ndi ofukula ndege: 5% ~ 8% motero;Kukula kosungidwa ndi kuchuluka kwake: 3% ~ 5%;Zotsalira zotsalira: 2% ~ 5%.
2) kutentha ntchito kutentha Sungunulani kuwotcherera ndi 280 ~ 300 ℃;liwiro loyenda ndi 2 ~ 3m / min;mawonekedwe owotcherera ndi kuwotcherera kwanjira ziwiri.
3) Kukonza njira ya ziwalo zowonongeka, zida zodula zomwe zili ndi zizindikiro zofanana, kugwirizanitsa kutentha kapena kusindikiza ndi guluu wapadera wa geomembrane.
4) Kulumikiza nsalu zopanda nsalu pa weld bead, geotextile composite kumbali zonse ziwiri za nembanemba imatha kuwotcherera ndi mfuti yowotcherera mpweya wotentha ngati ili pansi pa 150g/m2, ndipo makina osokera amatha kugwiritsidwa ntchito kusoka kupitirira 150g/m2.
5) Kusindikiza ndi kuyimitsa madzi kwa mphuno ya pansi pamadzi kudzasindikizidwa ndi chingwe cha GB rabara choyimitsa madzi, chokulungidwa ndi chitsulo ndikuchizidwa ndi anti-corrosion.
Kubwerera
1. Mukabwezeretsanso, liwiro la kubwereranso liyenera kuyendetsedwa molingana ndi zofunikira za mapangidwe ndi kukhazikitsa maziko.
2. Pagawo loyamba la kudzaza dothi pa zinthu za geosynthetic, makina odzazitsa amatha kuyenda motsatira njira yolumikizira zinthu za geosynthetic, ndipo makina opepuka (kupanikizika kosakwana 55kPa) ayenera kugwiritsidwa ntchito pofalitsa kapena kugudubuza.
