Inqubo yokubeka i-Geogrid:
Hlola futhi uhlanze ungqimba olungaphansi olungaphansi→wenza ngokuzenzela i-geogrid→goqana, bopha bese ulungisa→vula inhlabathi yezinga eliphezulu→ukugoqa→ukuhlola.
Izinto okufanele uziqaphele lapho ubeka i-geogrid:
(1) I-geogrid ibekwe phezu kongqimba oluphansi oluyisicaba ngokuya ngobubanzi obuhleliwe.Isendlalelo esingaphezulu esingaphansi sokugcwalisa asinawo udoti olungalimaza i-geogrid.Lapho ubeka i-geogrid, isiqondiso samandla aphezulu kufanele sibe yi-perpendicular ku-axis ye-embankment.isakhiwo.I-geogrid ibekwe ngokuvundlile.Qinisa futhi welule lapho ubeka ukuze uvimbele imibimbi, ukuhlanekezela noma imigodi.Ama-geogrid ahlukaniswa ngobude kusetshenziswa indlela egqagqene, futhi ububanzi obudlulanayo abukho ngaphansi kuka-20cm.
(2) Ngemva kokubeka i-geogrid, beka ngesandla ungqimba olungaphezulu lwe-filler bese uqeda ukugoqa ngesikhathi ukuze uvimbele ukuchayeka elangeni isikhathi eside.Bese usebenzisa ezokuthutha ngomshini, ukulinganisa nokugingqa.Ukugandaywa kwemishini nokugingqika kwenziwa kusukela emaphethelweni omabili kuya enkabeni, futhi ukugoqa kwenziwa kusukela emaphethelweni womabili kuya enkabeni, futhi idigri yokuhlanganisa igcinwa ukuze ihlangabezane nezidingo ezijwayelekile.
(3) Vimbela zonke izimoto zokwakha kanye nemishini yokwakha ekuhambeni noma ukupaka ku-geogrid egandayiwe.Hlola ikhwalithi ye-geogrid nganoma yisiphi isikhathi phakathi nokwakhiwa.Uma kutholakala noma yimuphi umonakalo ofana nokuphuka, ukubhoboza, noma ukuklebhuka, lungisa ngokwezinga.noma buyisela.
Indlela yokwakha ye-Geogrid:
(1) Okokuqala, yendlale ngokunembile umugqa wokuthambeka kombhede womgwaqo.Ukuze kuqinisekiswe ububanzi bombhede womgwaqo, uhlangothi ngalunye lunwetshwa ngo-0.5m.Ngemva kokulinganisa inhlabathi eyisisekelo eveziwe, sebenzisa irola yokudlidliza engu-25T ukuze uyicindezele kabili, bese usebenzisa irola yokudlidliza engu-50T ukuyicindezela izikhathi ezine., izinga lokubambisana lokwenziwa kwendawo elingalingani.
(2) Layisha isihlabathi esiphakathi nendawo (emaholoholo) esingu-0.3M, futhi ngemva kokulinganisa ngemishini ehlanganyelwayo, sebenzisa irola yokudlidliza engu-25T ukuze wenze ukucindezela okumile kabili.
(3) Beka i-geogrid.Lapho ubeka ama-geogrids, indawo engezansi kufanele ibe flat futhi iminyene.Ngokuvamile, kufanele zibekwe phansi, ziqondiswe, futhi zingapakishwa.Akufanele zisonte noma zisonte.Ama-geogrid amabili ancikene adinga ukweqa ngo-0.2m, futhi ama-geogrid kufanele agqitshwe ngokuphambana nombhede womgwaqo.Izingxenye zokuxhuma zixhunywe ngentambo yensimbi engunombolo 8 njalo ngemitha elingu-1, futhi igridi ebekiwe igxiliswa phansi ngezipikili ezimise okwe-U njalo ngo-1.5-2m.
(4) Ngemva kokuba ungqimba lokuqala lwe-geogrid selubekiwe, qala ugcwalise ungqimba lwesibili lwesihlabathi esiphakathi nendawo (emaholoholo) esiwugqinsi.Indlela iwukuthi: hambisa isihlabathi endaweni yokwakha ngemoto bese usithulula eceleni kombhede womgwaqo, bese usiphushela phambili ngogandaganda., qala ugcwalise u-0.1m phakathi kwamamitha angu-2 kuzo zombili iziphetho zombhede womgwaqo, usonge ungqimba lokuqala lwe-geogrid, bese ulugcwalisa ngesihlabathi esingu-0.1m esimaphakathi (amaholoholo).Akuvunyelwe ukugcwalisa nokusunduza iziphetho ezimbili phakathi nendawo, futhi zonke izinhlobo zemishini zivinjelwe.Uma usebenza ku-geogrid engagcwaliswanga ngesihlabathi esimaphakathi (esiqinile), lokhu kuzoqinisekisa ukuthi i-geogrid iyisicaba, iyaqhuma, futhi ayinamibimbi.Ngemuva kokuthi ungqimba lwesibili lwesihlabathi esiphakathi (esiqinile) siyisicaba, ukulinganisa okuvundlile kufanele kwenziwe.Ukuze uvimbele ukushuba kokugcwalisa okungalingani, sebenzisa i-roller edlidlizayo engu-25T ukuze uyicindezele kabili ngemva kokuba ilethiwe.
(5) Indlela yokwakha ungqimba lwesibili lwe-geogrid iyafana nesendlalelo sokuqala.Ekugcineni, yigcwalise ngesihlabathi esingu-0.3M esimaphakathi (amaholoholo).Indlela yokugcwalisa iyafana nesendlalelo sokuqala.Ngemva kokucindezela okumile kabili ngerola engu-25T, njengalena Ukuqiniswa kwesisekelo sombhede womgwaqo kuqediwe.
(6) Ngemva kokuba ungqimba lwesithathu lwesihlabathi esiphakathi nendawo (amaholoholo) lugoqwe, beka ama-geogrid amabili emikhawulweni yomibili yemithambeka ngobude eduze komugqa, udlule ngo-0.16m, futhi uwaxhume ngendlela efanayo, bese uqala ukwakhiwa komhlaba.Uma ubeka ama-geogrid ukuze uvikeleke emthambekeni, kuyadingeka ukukala imigqa yonqenqema yesendlalelo ngasinye, futhi uqinisekise ukuthi ama-geogrid angcwatshwa u-0.10m emthambekeni ngemva kokulungiswa kwemithambeka ohlangothini ngalunye.
(7) Kuzo zonke izingqimba ezimbili zenhlabathi egcwele i-slope geogrid, okungukuthi, lapho ukujiya kungu-0.8m, ungqimba lwe-geogrid ludinga ukubekwa kuzo zombili iziphetho, njalo njalo, luze lubekwe ngaphansi kwenhlabathi engaphezulu. ihlombe lomgwaqo.
(8) Ngemva kokugcwaliswa kombhede womgwaqo, umthambeka kufanele ulungiswe ngesikhathi, futhi ukuvikelwa kwemfucumfucu eyomile kufanele kwenziwe ngaphansi komthambeka.Ngaphezu kokunwetshwa kombhede ongu-0.3M ohlangothini ngalunye, u-1.5% wendawo yokuhlala kufanele ubekelwe eceleni.
