Geogrid alxanka birta ah oo leh awood xoog leh oo loogu talagalay dariiqa laamiga ee tareenka dhulka hoostiisa marinka tunnel
Faahfaahinta Alaabta
Fiberglass geogrid waa walxo geosynthetic ah oo aad u fiican oo loo isticmaalo xoojinta wadada, xoojinta wadadii hore, xoojinta saldhiga wadada iyo saldhiga ciidda jilicsan. Fiberglass geogrid waa alaab adag oo ka samaysan fiberglass aan lahayn alkali xoog sare leh iyada oo loo marayo habka tolida dagaal ee horumarsan ee caalamiga ah oo lagu dahaadhay daaweynta dusha sare. Waxa uu leeyahay awood cufan sare iyo elongation hooseeya in labada jihooyinka dagaal iyo weft, oo uu leeyahay sifooyin aad u fiican ee iska caabin heerkulka sare, caabbinta qabow hooseeyo, caabbinta gabowga, iska caabin daxalka, iwm Waxaa si weyn loo isticmaalaa in laami laami, laami sibidhka iyo xoojinta wadada. Jidka tareenada, ilaalinta jiirada biyo-xireenka, dhabada dayuuradaha ee garoonka diyaaradaha, xakamaynta ciidda iyo mashaariicda kale ee injineernimada.
Qaybta ugu muhiimsan ee fiberglass waa: Silicon oxide, waa maaddooyin aan organic ahayn, sifooyinka jidheed iyo kiimiko waa kuwo aad u deggan, waxayna leedahay module sare, xirashada caabbinta iyo caabbinta qabow ee heer sare ah, ma laha gurguurta muddada dheer; xasilloonida kulaylka wanaagsan; qaab dhismeedka mesh si ay isu geynta quful iyo xaddid u yeelato; wanaaji awoodda rarka ee isku dhafka asphalt. Sababtoo ah dusha sare waxaa lagu dahaadhay asphalt gaar ah oo wax laga beddelay, waxay leedahay laba siyood oo isku dhafan, labadaba sifooyinka wanaagsan ee fiberglass iyo iswaafajinta isku dhafka asphalt, taas oo hagaajinaysa caabbinta nabarka iyo caabbinta dhogorta ee geogrid.
Astaamaha alaabada geogrid fiberglass
Badeecadu waxay leedahay xoog sare, elongation hooseeya, iska caabin heerkul sarreeya, modules sare, miisaanka fudud, adkaanta wanaagsan, caabbinta daxalka, nolosha dheer, iwm Waxaa si ballaaran loo isticmaali karaa in laami hore sibidhka, dayactirka garoonka dayuuradaha, embankment, bangiga webiga, ilaalinta jiirada, daawaynta tayeynta wadada iyo buundada iyo beeraha kale ee injineernimada, kuwaas oo ku siin kara wanaajinta laamiga, xoojinta, ka hortagga dillaaca daal laamiga, dildillaac kulul iyo qabow qabow iyo milicsiga hoos ku. iyo kala firdhisan kartaa, dheerayn kartaa nolosha adeegga ee laamiga, xoog cufnaanta sare elongation hoose, ma gurguurta muddada-dheer, xasilooni jireed iyo kiimiko wanaagsan, xasilloonida kulaylka wanaagsan, daal iska caabin ah, caabbinta heerkul sare, heerkul hoose yaraynta dildilaaca iska caabin ah, hoos u dhac dildilaaca milicsiga.
Habka dhismaha Fiberglass geogrid
(1) Marka hore, si sax ah u demi xariiqda jiirada ee sariirta, si loo hubiyo ballaca wadada, dhinac kasta waxaa lagu ballaariyay 0.5m, qalajinta carrada substrate wanaagsan si loo simo ka dib markii la isticmaalo 25T cadaadiska gariirada laba jeer, ka dibna 50T cadaadis shoog afar jeer, meesha aan sinnayn oo leh heerka gacanta.
(2) Dejinta 0.3m dhumuc dhexdhexaad ah (dhaxaad ah) ciid, buug-gacmeed leh heerar farsamo, 25T rullaluistemadka gariirka cadaadiska laba jeer.
(3) dhigista geogrid, gogoldhigga dhulka hoose ee geogrid waa inuu ahaadaa mid siman, cufan, guud ahaan waa in la dhigaa si siman, toosan, isku dhejin, la'aan, labbis la'aan, kink, laba geogrid oo isku xigta waxay u baahan yihiin in ay ku dhuftaan 0.2m, iyo qayb kasta oo ka mid ah dhabta geogrid ee wadada sariirta ah mid kasta 1m oo leh siligga No. 8 ee isku xirka isku xirka, iyo shabaqyada la dhigay, 1.5-2m kasta oo leh cidiyaha U-cidida dhulka.
(4) lakabka ugu horreeya ee geogrid laami ah, wuxuu bilaabay inuu buuxiyo lakabka labaad ee dhumucdiisuna tahay 0.2m ee ciid (cufan), habka: carrada baabuur ee goobta laga soo dejiyo dhinaca dhinaca wadada, ka dibna isticmaal cagafyada si aad hore ugu riixdo. , 2 mitir ee ugu horreeya labada dhinac ee sariirta ka dib buuxinta 0.1m, lakabka koowaad ee geogrid ayaa laalaabmay ka dibna waxaa lagu buuxiyey 0.1m (camuud aan dhab ahayn), ka mamnuuc labada dhinacba dhexe ee buuxinta iyo horusocodka, mamnuuc dhammaan noocyada mashiinada maqnaanshaha Tani waxay xaqiijin kartaa in geogrid uu yahay mid siman, oo aan lahayn durbaan iyo laalaab, iyo ka dib markii lakabka labaad ee ciid dhexdhexaad ah (aan qalafsaneyn) la siman yahay, cabbirka heerka waa in la qaadaa. Si looga hortago dhumucda buuxinta aan sinnayn, iyo 25T rullaluistemadka gariirku waa in la isticmaalaa laba jeer ka dib marka heerku sax yahay.
(5) lakabka labaad ee habka dhismaha geogrid oo leh lakabka koowaad ee isku midka ah, iyo ugu dambeyntii buuxi 0.3m ee ciid (aan qallafsaneyn), buuxinta habka isku midka ah ee lakabka koowaad, oo leh cadaadiska 25T roller static laba jeer, si Xoojinta substrate-ka waddada goglan waa la dhammaystiray.
(6) lakabka saddexaad ee ciidda (qaar-qaran) oo la jajabiyey, oo ay weheliyaan khadka waddada dheer ee labada dhinac ee jiirarka ayaa la dhigay geogrid laba, dhabanno 0.16m ah, oo isku mid ah oo isku mid ah, ka dibna bilaabaya hawlaha dhismaha dhulka, dhejinta geogrid Ilaalinta jiirada, lakab kasta waa in laga cabbiraa cidhifka jiifinta, dhinac kasta si loo hubiyo in jiirada dayactirka geogrid ku aasay jiirada 0.10m.
(7) Labadii lakab ee ciidda la buuxiyey, 0.8m oo dhumucdeedu tahay, lakabka geogrid waa in la dhigaa labada dhinac isku mar, ka dibna sidaas oo kale ilaa ay ka gaadho dusha garabka wadada.
(8) ka dib marka la buuxiyo gogosha wadada, dayactirka jiirada wakhtiga, iyo ilaalinta dhagaxa qallalan ee cagta ee jiirada, qaybta gogosha wadada marka lagu daro ballaarinta 0.3m ee dhinac kasta, oo loo qoondeeyay 1.5% qashinka.
