Njira yopangira Geogrid:

Yang'anani ndi kuyeretsa m'munsi → ikani geogrid pamanja → kupindika, kumanga ndi kukonza → konza dothi lapamwamba → kugudubuza → kuyang'ana.

Zomwe muyenera kuzidziwa mukayika geogrid:

(1) Geogrid imayikidwa pagawo lathyathyathya lokhala pansi molingana ndi m'lifupi mwake.Chipinda cham'mwamba cha zodzaza ndi zopanda zinyalala zomwe zingawononge geogrid.Poika geogrid, mayendedwe amphamvu kwambiri ayenera kukhala perpendicular kwa olamulira a mpanda.kamangidwe.Geogrid imayikidwa mozungulira.Mangitsani ndi kutambasula pogona kuti mupewe makwinya, kupotoza kapena maenje.Ma geogrid amapangidwa motalika kwambiri pogwiritsa ntchito njira yodutsana, ndipo m'lifupi mwake sichepera 20cm.
(2) Mukayala geogrid, ikani pamanja gawo lapamwamba la filler ndikumaliza kugubuduza munthawi yake kuti muteteze kudzuwa kwa nthawi yayitali.Kenako gwiritsani ntchito zoyendera zamakina, kusanja ndi kugudubuza.Kuyika kwamakina ndi kugubuduza kumachitika kuchokera malekezero onse mpaka pakati, ndipo kugubuduza kumachitika kuchokera malekezero onse mpaka pakati, ndipo digiri ya compaction imasungidwa kuti ikwaniritse zofunikira.
(3) Kuletsa magalimoto onse omanga ndi makina omanga kuyenda kapena kuyimitsidwa pa geogrid yoyala.Onani mtundu wa geogrid nthawi iliyonse pakumanga.Ngati chiwonongeko chilichonse ngati chosweka, kubowola, kapena kung'ambika chikapezeka, chikonzeni molingana ndi kukula kwake.kapena kusintha.

Njira yomanga ya Geogrid:

(1) Choyamba, yalani bwinobwino mzere wotsetsereka.Pofuna kuonetsetsa kuti m'lifupi mwa msewu, mbali iliyonse imakulitsidwa ndi 0.5m.Mukayika dothi lowonekera, gwiritsani ntchito 25T vibratory roller kuti muyinikize kawiri, kenako gwiritsani ntchito 50T vibratory roller kuti muyinikize kanayi., kusalinganika kwa mgwirizano wapagulu.
(2) Yalani mchenga wokhuthala wa 0.3M, ndipo mutatha kuwongolera ndi makina ogwiritsira ntchito pamanja, gwiritsani ntchito chogudubuza cha 25T kuti mupumitse kawiri.
(3) Ikani geogrid.Mukayika ma geogrids, pansi payenera kukhala lathyathyathya komanso wandiweyani.Nthawi zambiri, ziyenera kukhala zosalala, zowongoka, osati zomanga.Sayenera kupindika kapena kupindika.Ma geogrid awiri oyandikana amayenera kupitirana ndi 0.2m, ndipo ma geogrids ayenera kupitirana mopingasa m'mphepete mwa msewu.Zigawo zogwirizanitsa zimagwirizanitsidwa ndi waya wachitsulo nambala 8 pa mita imodzi iliyonse, ndipo gridi yoyikidwa imakhazikika pansi ndi misomali yofanana ndi U iliyonse 1.5-2m.
(4) Gawo loyamba la geogrid likayalidwa, choyamba lembani mchenga wachiwiri wa 0.2m wokhuthala (wosanjikiza).Njira ndi: kunyamula mchenga kupita kumalo omangapo ndi galimoto ndikuutsitsa m'mbali mwa msewu, ndiyeno nkukankhira kutsogolo ndi bulldozer., choyamba lembani 0.1m mkati mwa 2 mamita kumapeto onse a msewu, pindani gawo loyamba la geogrid, ndiyeno mudzaze ndi 0.1m wa mchenga wapakati (wowawa kwambiri).Ndizoletsedwa kudzaza ndi kukankhira mbali ziwirizo pakati, ndipo mitundu yonse ya makina ndi yoletsedwa.Pogwira ntchito pa geogrid yomwe sinadzazidwe ndi mchenga wapakati (wobiriwira), izi zidzatsimikizira kuti geogrid ndi yophwatalala, yotupa, komanso yopanda makwinya.Mchenga wachiwiri wapakati (wosanjikiza) ukakhala wathyathyathya, muyeso wopingasa uyenera kuchitidwa.Kuti mupewe makulidwe osakwanira odzaza, gwiritsani ntchito chogudubuza cha 25T kuti muyinikize kawiri ikatha.
(5) Njira yopangira gawo lachiwiri la geogrid ndi yofanana ndi yoyamba.Pomaliza, mudzaze ndi mchenga wa 0.3M wapakati (wolimba).Njira yodzaza ndi yofanana ndi yoyamba.Pambuyo pa kukanikiza kawiri kawiri ndi 25T roller, monga chonchi Kulimbitsa kwapansi kwa msewu kumatsirizidwa.
(6) Pambuyo wosanjikiza wachitatu wa sing'anga (coarse) mchenga ndi adagulung'undisa, ikani geogrids awiri malekezero onse otsetsereka longitudinally motsatira mzere, palimodzi ndi 0.16m, ndi kulumikiza iwo chimodzimodzi, ndiyeno kuyamba earthwork yomanga.Mukayika ma geogrids kuti muteteze malo otsetsereka, ndikofunikira kuyeza mizere ya m'mphepete mwa wosanjikiza uliwonse, ndikuwonetsetsa kuti ma geogrids amakwiriridwa 0.10m potsetsereka pambuyo pokonza otsetsereka mbali iliyonse.
(7) Pa magawo awiri aliwonse a dothi lodzaza ndi geogrid yotsetsereka, ndiye kuti, makulidwe ake ndi 0.8m, gawo la geogrid liyenera kuyikidwa mbali zonse ziwiri, ndi zina zotero, mpaka litayikidwa pansi pa nthaka ya nthaka. msewu phewa.
(8) Pambuyo podzaza msewuwo, malo otsetsereka ayenera kukonzedwanso nthawi yake, ndipo chitetezo cha zinyalala zowuma chiyenera kuchitidwa pamunsi mwa malo otsetsereka.Kuphatikiza pakukulitsa msewu ndi 0.3M mbali iliyonse, 1.5% ya malowa iyenera kusungidwa.
