Nkhani

M'malo mwake, kuyika kwa geotextile sikovuta kwambiri, ndipo tiyenera kugwira ntchito molingana ndi zofunikira popanda vuto lililonse.Ngati simukudziwa kuyika geotextile, mutha kuyang'ana zomwe zili m'nkhaniyi poyamba, zomwe zingakhale zothandiza kwa inu kuti mutsegule geotextile.
Kuyika kwa geotextile sikuli kovuta kwambiri
1. Kuyika kwa geotextile.Pakuyika, ogwira ntchito yomanga ayenera kutsatira mfundo ya "kuchokera pamwamba mpaka pansi" malinga ndi geotextile.Malinga ndi kupatuka ofukula kwa olamulira, sikofunikira kusiya kugwirizana kwapakati longitudinal mng'alu.Panthawi yomangayi, ogwira ntchito yomangayo ayenera kumvetsera chilango cha chithandizo cha maziko kuti atsimikizire kuti malo opangidwa ndi athyathyathya ndi oyera.Pofuna kupewa malo osagwirizana pamtunda wodutsapo ndikukonza ming'alu ya pamwamba, m'pofunikanso kufunsa ndi kupeza nthaka yolimba.Poyala, ogwira ntchito yomanga sayenera kuvala nsapato zolimba kwambiri kapena kukhala ndi misomali pansi.Kuti muteteze bwino zida, muyenera kusamala posankha zinthu zofukiza.Pofuna kupewa kuwonongeka kwa nembanemba chifukwa cha mphepo, matumba a mchenga kapena zinthu zina zofewa ziyenera kugwiritsidwa ntchito pazinthu zonse panthawi yoyikapo kuti zipereke chilango chokhwima, kuti akhazikitse maziko abwino oyika zipangizo.
2. Kusoka kwa geotextile ndi kuwotcherera.Pogwirizanitsa zinthu, ogwira ntchito yomanga ayenera kutsatira mfundo yoyankhira kuti atsimikizire kuti kugwirizana kuli koyenera.Choyamba, sokani pansi geotextile kuti alangidwe, kenako kumata pakati pa geotextile, ndiyeno soka pamwamba geotextile kuti alangidwe.Asanayambe kumanga kuwotcherera, akatswiri omangamanga ayenera kuyang'ana njira yowotcherera kuti adziwe kutentha ndi kuthamanga kwa makina owotcherera pa tsiku lomanga, ndi kupanga zosintha zoyenera malinga ndi momwe zimakhalira.Pamene kutentha kuli pakati pa 5 ~ 35 ℃, kuwotcherera ndikoyenera kwambiri.Ngati kutentha pa tsiku lomanga sikuli mkati mwamtunduwu, akatswiri a zomangamanga ayenera kumaliza ntchitoyo ndi kufunafuna kusintha koyenera.Musanawotchere, zonyansa zomwe zili pamtunda ziyenera kutsukidwa kuti zowotcherera zikhale zoyera.Chinyezi chomwe chili pamtunda wowotcherera chikhoza kuumitsidwa ndi chowumitsira tsitsi chamagetsi.The kuwotcherera pamwamba akhoza kukhala youma.Polumikizana ndi ma geotextiles angapo, ming'alu yolumikizana imayenera kugwedezeka kupitilira 100cm, ndipo mfundo zowotcherera ziyenera kukhala zooneka ngati T.Node zowotcherera sizingakhazikitsidwe ngati mawonekedwe opingasa.Pambuyo pomanga kuwotcherera kumalizidwa, kuwongolera khalidwe la kugwirizana kudzachitidwa pofuna kupewa kuwotcherera kutayikira, kupindika ndi mavuto ena osafunika.Pa kuwotcherera ndi mkati mwa maola awiri mutatha kuwotcherera, kuwotcherera pamwamba sikudzakhala pansi pa kupsinjika kwamphamvu kuti mupewe kuwonongeka kwa malo owotcherera.Mu kuwotcherera khalidwe anayendera, ngati pali mavuto aakulu kuwotcherera, monga kuwotcherera opanda kanthu, kuwotcherera kuwonjezera, kuwotcherera ogwira ntchito ayenera kudula malo kuwotcherera, mawonekedwe mawonekedwe pambuyo kuwotcherera ndi zina latsopano chilango kuwotcherera.Ngati pali kutayikira m'malo owotcherera, ogwira ntchito kuwotcherera ayenera kugwiritsa ntchito mfuti yapadera yowotcherera pokonza zowotcherera.Akamisiri owotcherera akawotcherera geotextile, amayenera kuwotcherera zomwe amawotchera motsatana ndi kapangidwe kake kuti atsimikizire kuti mtundu wa kuwotcherera ukukwaniritsa miyezo yoyenera.Geotextile iyenera kuyimira kwathunthu mphepo yosalowa.
3. Geotextile kusoka.Pindani kumtunda kwa geotextile ndi geotextile yapakati kumbali zonse ziwiri, kenako pindani, kupindika, kugwirizanitsa ndi kusoka geotextile yapansi.Makina osokera m'manja amagwiritsidwa ntchito kusoka geotextile, ndipo mtunda woyenda molunjika umayendetsedwa mkati mwa 6mm.Pamalo olumikizana ndi omasuka pang'ono komanso osalala, ndipo geotextile ndi geotextile ali pamavuto olumikizana.Miyezo yolumikizira kumtunda kwa geotextile ndi yofanana ndi yapansi ya geotextile.Malingana ngati titsatira njira zomwe zili pamwambazi, pasakhale mavuto.Komabe, tiyenera kusamala pakukonza mphamvu ya geotextile mtsogolomo.
