I-geogrid yepulasitiki yensimbi enamandla okuthwala yomgwaqo ogandayiwe wesitimela ongaphansi komhubhe
Imininingwane Yomkhiqizo
I-Fiberglass geogrid iyinto enhle kakhulu ye-geosynthetic esetshenziselwa ukuqinisa umgwaqo, ukuqinisa umgwaqo omdala, ukuqinisa isisekelo somgwaqo kanye nesisekelo senhlabathi ethambile. I-Fiberglass geogrid iwumkhiqizo oqinile owenziwe nge-fiberglass enamandla amakhulu engena-alkali ngenqubo yokuluka ye-warp ethuthukisiwe yamazwe ngamazwe futhi yambozwa ngokwelashwa kwendawo. Inamandla aqinile aqinile kanye nobude obuphansi kuzo zombili izikhombisi-ndlela ze-warp kanye ne-weft, futhi inezindawo ezinhle kakhulu zokumelana nezinga lokushisa eliphezulu, ukumelana nokubanda okuphansi, ukumelana nokuguga, ukumelana nokugqwala, njll. Isetshenziswa kakhulu endaweni egandaywe itiyela, ekugandayweni kukasimende nasekuqiniseni umbhede womgwaqo futhi umgwaqo wesitimela, ukuvikelwa kwemithambeka yedamu, umzila wezindiza zezindiza, ukulawulwa kwesihlabathi kanye neminye imiklamo yobunjiniyela.
Ingxenye eyinhloko ye-fiberglass yile: i-silicon oxide, i-inorganic materials, izakhiwo zayo ezingokwenyama namakhemikhali zizinzile ngokwedlulele, futhi ine-modulus ephezulu, ukumelana nokugqoka kanye nokumelana nokubanda okuhle kakhulu, akukho mkhuba wesikhathi eside; ukuzinza okuhle kokushisa; Isakhiwo se-mesh ukuze i-aggregate eshumekiwe yokukhiya nomkhawulo; ngcono umthamo wokuthwala umthwalo wengxube ye-asphalt. Ngenxa yokuthi ingaphezulu limbozwe i-asphalt ekhethekile eguquliwe, inezici ezimbili ezihlanganisiwe, kokubili izakhiwo ezinhle kakhulu ze-fiberglass kanye nokuhambisana nengxube ye-asphalt, ethuthukisa ukumelana nokuhuzuka kanye nokumelana nokugundwa kwe-geogrid.
Izici zemikhiqizo ye-fiberglass geogrid
Umkhiqizo unamandla aphezulu, ubude obuphansi, ukumelana nokushisa okuphezulu, i-modulus ephezulu, isisindo esincane, ukuqina okuhle, ukumelana nokugqwala, impilo ende, njll. ukuvikelwa kwemithambeka, ukwelashwa kokuthuthukiswa komgwaqo kanye nebhuloho kanye nezinye izinkambu zobunjiniyela, ezinganikeza ukuthuthukiswa kwendlela yokuhamba ngezinyawo, ukuqinisa, ukuvimbela ukuguquguquka kokukhathala, ukushisa kanye nokuqhekeka okubandayo okubandayo kanye nokuqhekeka kwe-reflection ngezansi, futhi kungahlakazeka, kunwebe impilo yensizakalo yokugandaywa kwezinyawo, amandla aqinile aqinile ukuphakama okuphansi, akukho kukhasa isikhathi eside, ukuzinza okuhle ngokomzimba namakhemikhali, ukuzinza okuhle kokushisa, ukumelana nokuqhekeka kokukhathala, ukumelana nokushisa okuphezulu kokushisa. , izinga lokushisa eliphansi lokumelana nokuqhekeka kwe-shrinkage, ukunciphisa ukulibaziseka kwemifantu yokubonisa.
Inqubo yokwakha i-Fiberglass geogrid
(1) Okokuqala, khipha ngokunembayo umugqa wemithambeka wombhede womgwaqo, ukuze uqinisekise ububanzi bombhede womgwaqo, uhlangothi ngalunye lunwetshwa ngo-0.5m, ukomiswa kwenhlabathi engaphansi ukuze ilingane ngemva kokusebenzisa i-25T vibratory roller static pressure. izikhathi ezimbili, bese kuba ngu-50T ukushaqeka ingcindezi izikhathi ezine, indawo engalingani nge leveling manual.
(2) Ibeka isihlabathi esingu-0.3m esiwugqinsi esimaphakathi (amaholoholo), imanuwali enokulinganisa ngomshini, ingcindezi emile engu-25T yerola yokudlidliza izikhathi ezimbili.
(3) ukubeka i-geogrid, i-geogrid ebeka indawo engezansi kufanele ibe isicaba, iminyene, ngokuvamile kufanele ibekwe isicaba, iqonde, kungabikho ukugqagqana, akukho ukugoqa, i-kink, i-geogrid emibili esondelene idinga ukugoqa u-0.2m, futhi eduze kombhede ongemuva we-geogrid lap ingxenye ngayinye 1m ngentambo engu-No. 8 ukuze ixhumeke, futhi kumagridi abekiwe, njalo ngo-1.5-2m Izinzipho zika-U zigxiliswe phansi.
(4) ungqimba lokuqala lwe-geogrid egandayiwe, lwaqala ukugcwalisa ungqimba lwesibili oluwugqinsi oluwu-0.2m esihlabathini ( esimahhadla), indlela: isihlabathi semoto esiyisa endaweni sehliswe eceleni kombhede womgwaqo, bese usebenzisa ibhuldoza ukuphushela phambili. , amamitha okuqala angu-2 kuzo zombili izinhlangothi zombhede womgwaqo ngemva kokugcwalisa u-0.1m, ungqimba lokuqala lwe-geogrid luyagoqwa lwase lugcwaliswa ngo-0.1m ku-(maholoholo) isihlabathi, ukuvimbela izinhlangothi zombili ukuya maphakathi ukugcwaliswa kanye kusengaphambili, vimbela zonke izinhlobo zemishini lapho kungekho Lokhu kungaqinisekisa ukuthi geogrid isicaba, ngaphandle izigubhu nemibimbi, futhi ngemva ungqimba lwesibili lwesihlabathi medium (amaholoholo) isicaba. , isilinganiso sezinga kufanele senziwe ukuvimbela ukushuba kokugcwalisa okungalingani, futhi i-roller yokudlidliza engu-25T kufanele isetshenziselwe izikhathi ezimbili ngemva kokuba ukulinganisa kulungile.
5 ukuqiniswa kwe-roadbed substrate kuqediwe.
6 ukuze kuvikelwe i-slope, ungqimba ngalunye kufanele lulinganiswe ngaphandle konqenqema lokubeka, uhlangothi ngalunye ukuze kuqinisekiswe ukuthi i-geogrid yokulungisa i-slope igqitshwe umthambeka 0.10m.
(7) Kuzo zonke izingqimba ezimbili zenhlabathi egcwalisiwe, okungukuthi u-0.8m ubukhulu, ungqimba lwe-geogrid kufanele lubekwe nhlangothi zombili ngesikhathi esisodwa, bese luqhubeka njalo luze lufike phezu kwehlombe lomgwaqo.
(8) ngemva kokugcwaliswa kombhede womgwaqo, ukulungiswa kwemithambeka ngesikhathi, nokuvikelwa kwamatshe omile phansi komthambeka, ingxenye yombhede womgwaqo ngaphezu kokunwetshwa okungu-0.3m ohlangothini ngalunye, futhi igcine u-1.5% wokucwila emanzini.
