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 lwesihlabathi esimaphakathi, esimahhadla, nesihlabathi. Ukulinganisa okuvundlile kufanele kwenziwe ukuvimbela ukushuba kokugcwalisa okungalingani. Ngemva kokulinganisa ngaphandle kwamaphutha, i-roller 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.
