Izindaba

1. Okokuqala, beka ngokunembile umugqa wokuthambeka kombhede womgwaqo.Ukuze kuqinisekiswe ububanzi bombhede womgwaqo, uhlangothi ngalunye lunwetshwa ngo-0.5m.Ngemva kokulinganisa inhlabathi eyisisekelo eyomile, sebenzisa i-roller edlidlizayo engu-25T ukuze ucindezele i-static kabili.Bese usebenzisa ingcindezi yokudlidliza engu-50T izikhathi ezine, futhi uleveli ngokuzenzakalelayo izindawo ezingalingani.
2. Gcoba u-0.3m owugqinsi ophakathi nendawo, amaholoholo, nesihlabathi, futhi uleveli ngesandla ngemishini.Ingcindezi eqinile kabili ngerola edlidlizayo engu-25T.
3. Lay geogrid.Lapho ubeka ama-geogrid, indawo engaphansi kufanele ibe isicaba, iminyene, futhi ngokuvamile ibe isicaba.Qondisa, ungagqagqani, ungagoqeki, ungasonti, futhi udlulele kuma-geogrid aseduze ngo-0.2m.Izingxenye ezigqagqene zama-geogrid kufanele zixhunywe ngezintambo zensimbi ezingu-8 # njalo ngemitha elingu-1 ngendlela evundlile yombhede womgwaqo, futhi zibekwe kuma-geogrid abekiwe.Lungisa phansi nge-U-nails njalo nge-1.5-2m.
4. Ngemva kokubekwa kongqimba lokuqala lwe-geogrid, ungqimba lwesibili oluwugqinsi oluphakathi no-0.2m, olumahhadla, nesihlabathi luyagcwaliswa.Indlela yokuthutha isihlabathi usiyise lapho kwakhiwa khona bese usithulula ohlangothini olulodwa lombhede womgwaqo, bese usebenzisa ibhuldoza ukuphushela phambili.Okokuqala, gcwalisa u-0.1m phakathi kwebanga lamamitha angu-2 ezinhlangothini zombili zombhede womgwaqo, bese ugoqa ungqimba lokuqala lwe-geogrid bese ulugcwalisa ngo-0.1m ophakathi nendawo, omahhadla, nesihlabathi.Vimbela ukugcwalisa nokusunduza kusuka ezinhlangothini zombili kuya maphakathi, futhi uvimbele imishini ehlukahlukene ukuthi ingadluli futhi isebenze ku-geogrid ngaphandle kokugcwalisa, amaholoholo, nesihlabathi.Lokhu kungaqinisekisa ukuthi i-geogrid iyisicaba, ayigobile, noma iyashwabana, futhi ilinde ungqimba lwesibili lwe-medium, mahhola, nesihlabathi ukuthi lulinganiswe.Ukulinganisa okuvundlile kufanele kwenziwe ukuvimbela ukushuba kokugcwalisa okungalingani.Ngemva kokulinganisa ngaphandle kwamaphutha, i-rola edlidlizayo engu-25T kufanele isetshenziselwe ukucindezela okumile kabili.
5. Indlela yokwakha ungqimba lwesibili lwe-geogrid iyafana neyesendlalelo sokuqala.Ekugcineni, gcwalisa u-0.3m wesilinganiso esimaphakathi, esimahhadla, nesihlabathi ngendlela yokugcwalisa efanayo neyesendlalelo sokuqala.Ngemva kokudlula okubili kokucindezela okumile ngerola engu-25T, ukuqiniswa kwesisekelo sombhede womgwaqo kuyaqedwa.
6. Ngemva kokuba ungqimba lwesithathu lwe-medium, i-coarse, nesihlabathi luhlanganisiwe, ama-geogrid amabili abekwa ngobude eduze komugqa ezinhlangothini zombili zomthambeko, adlulele ngo-0.16m, futhi axhunywe kusetshenziswa indlela efanayo ngaphambi kokuqala umsebenzi wokwakha umsebenzi womhlaba.Beka ama-geogrid ukuze uvikeleke emthambekeni.Imigqa yonqenqema ebekiwe kufanele ikalwe kusendlalelo ngasinye.Uhlangothi ngalunye kufanele luqinisekise ukuthi i-geogrid ingcwatshwa ngaphakathi kuka-0.10m wethambeka ngemva kokulungiswa komthambeka.
7. Uma ugcwalisa izingqimba ezimbili zenhlabathi ngogqinsi luka-0.8m, ungqimba lwe-geogrid ludinga ukubekwa ezinhlangothini zombili zomthambeko ngesikhathi esisodwa.Khona-ke, njalonjalo, kuze kube yilapho ibekwe ngaphansi kwenhlabathi ebusweni behlombe lomgwaqo.
8. Ngemva kokugcwaliswa kombhede womgwaqo, umthambeko kufanele ulungiswe ngesikhathi esifanele.Futhi unikeze ukuvikeleka kwemfucumfucu eyomile ngaphansi komthambeko.Ngaphezu kokwandisa uhlangothi ngalunye ngo-0.3m, indawo yokuhlala engu-1.5% iphinde ibekelwe lesi sigaba sombhede womgwaqo.
