Nkhani

Kuyika kwa geotextile sikuli kovuta kwambiri. Nthawi zambiri, sipadzakhala mavuto mukafunika kugwira ntchito molingana ndi zofunikira. Ngati simukudziwa kuyala ma geotextiles, mutha kuyang'ana zomwe zafotokozedwa m'nkhaniyi, zomwe zingakhale zothandiza kwa inu kuyala ma geotextiles.

1. Kuyika kwa geotextile. Ogwira ntchito yomanga ayenera kutsatira mfundo ya pamwamba-pansi malinga ndi geotextile panthawi yoyika. Malinga ndi kupatuka ofukula kwa olamulira, palibe chifukwa chosiya kugwirizana kwapakati longitudinal mng'alu. Munthawi yomanga iyi, ogwira ntchito yomanga ayenera kulabadira chilango cha maziko a chithandizo kuti malo omangidwawo akhale athyathyathya komanso aukhondo. Pofuna kupewa malo osagwirizana pamtunda wapansi ndikukonza ming'alu pamtunda, m'pofunikanso kufunsa ndikuchezera kulimba kwa nthaka. Panthawi yoyika, ogwira ntchito yomanga sayenera kuvala nsapato zolimba kwambiri kapena kukhala ndi misomali pansi. M'pofunikanso kusamala posankha chinthu fuzzing kuti bwino kuteteza zinthu. Pofuna kupewa kuwonongeka kwa nembanemba komwe kumachitika chifukwa cha mphepo, zipangizo zonse ziyenera kulangidwa kwambiri ndi matumba a mchenga kapena zinthu zina zofewa panthawi yoyika, ndikuyika maziko abwino opangira zipangizo.
2. Geotextile kusoka ndi kuwotcherera. Pogwirizanitsa zinthu, ogwira ntchito yomanga ayenera kutsatira mfundo yoyankhira kuti atsimikizire kuti kugwirizana kuli koyenera. Choyamba, geotextile yapansi idzasokedwera chilango, ndiye kuti geotextile yapakati idzamangirizidwa, ndiyeno pamwamba pa geotextile idzasokedwera chilango. Asanayambe kumanga kuwotcherera, akatswiri omangamanga ayenera kuyang'ana njira yowotcherera kuti adziwe kutentha ndi kuwongolera liwiro la makina owotcherera pa tsiku lomanga, ndikusintha koyenera malinga ndi momwe zimakhalira. Kutentha kukakhala pakati pa 5 ndi 35 ℃, kuwotcherera ndikoyenera. Ngati kutentha kwa tsiku lomanga sikuli mkati mwamtunduwu, amisiri omangawo ayenera kumaliza ntchitoyo ndikufunafuna kuwongolera koyenera. Pamaso kuwotcherera, zonyansa pa kuwotcherera pamwamba ayenera kutsukidwa kuonetsetsa ukhondo wa kuwotcherera pamwamba. Chinyezi chomwe chili pamtunda wowotcherera chimatha kuyanika ndi chowumitsira tsitsi chamagetsi. Pamwamba pa kuwotcherera akhoza kukhala youma. Pakulumikizana kwa ma geotextiles angapo, ming'alu yolumikizana iyenera kugwedezeka ndi kupitilira 100cm, ndipo zolumikizira zowotcherera ziyenera kukhala zooneka ngati T, ndipo zolumikizira sizingakhazikitsidwe ngati zopingasa. Akamaliza kuwotcherera yomanga, kulamulira khalidwe kugwirizana ayenera kuchitidwa kupewa kuwotcherera kutayikira, pindani ndi mavuto ena chokhwima. Pa kuwotcherera ndi mkati mwa maola awiri mutatha kuwotcherera, kuwotcherera pamwamba sikudzakhala pansi pa kupsinjika kwamphamvu kuti mupewe kuwonongeka kwa malo owotcherera. Ngati mavuto aakulu kuwotcherera amapezeka mu kuwotcherera khalidwe anayendera, monga kuwotcherera chopanda, kuwotcherera kuwonjezera, kuwotcherera antchito ayenera kudula malo kuwotcherera, kuwotcherera mawonekedwe udindo ndi zina latsopano kuwotcherera chilango. Ngati pali kutayikira m'malo owotcherera, ogwira ntchito kuwotcherera ayenera kugwiritsa ntchito mfuti yapadera yowotcherera pokonza ndi kutaya. Akawotcherera geotextile, katswiri wazowotcherera amayenera kuwotcherera geotextile mosamalitsa malinga ndi kapangidwe kake kuti awonetsetse kuti mtundu wa kuwotcherera ukukwaniritsa zofunikira, ndipo geotextile iyenera kuwonetsa bwino mphepo yosawotchera.
3. Kusoka kwa geotextile. Pindani kumtunda kwa geotextile ndi geotextile wapakati kumbali zonse ziwiri, kenako pindani, kupindika, kugwirizanitsa ndi kusoka geotextile yapansi. Makina osokera pamanja amagwiritsidwa ntchito kusoka kwa geotextile, ndipo mtunda woyenda molunjika umayendetsedwa mkati mwa 6 mm. Pamalo olumikizana ndi omasuka pang'ono komanso osalala, ndipo geotextile ndi geotextile ali pamavuto olumikizana. Miyezo yakutsogolo ya geotextile ndi yofanana ndi miyeso yapansi ya geotextile. Malingana ngati njira zomwe zili pamwambazi zikutsatiridwa, nthawi zambiri, sikuyenera kukhala ndi mavuto, koma muyenera kumvetseranso kukonzanso mphamvu ya geotextile m'tsogolomu.
