Iindaba

1. Okokuqala, misela ngokuchanekileyo umgca wokuthambeka kwendlela yendlela.Ukuze kuqinisekiswe ububanzi bendlela, icala ngalinye liyandiswa nge-0.5m.Emva kokulinganisa umhlaba osisiseko owomileyo, sebenzisa i-25T i-vibrating roller ukucinezela i-static kabini.Emva koko sebenzisa uxinzelelo lokungcangcazela kwe-50T amaxesha amane, kwaye wenze inqanaba ngesandla iindawo ezingalinganiyo.
2. Igaqa nge-0.3m ubukhulu obuphakathi, irhabaxa, kunye nesanti, kunye nenqanaba ngesandla ngoomatshini.Uxinzelelo lwe-static kabini kunye ne-25T i-vibrating roller.
3. Lay geogrid.Xa ubeka i-geogrids, umgangatho ongezantsi kufuneka ube mcaba, uxinene, kwaye ngokubanzi.Qinisa, musa ukugqithelana, musa ukugoba, ukujija, kwaye ugqithe kwii-geogrids ezikufutshane nge-0.2m.Amacandelo adibeneyo e-geogrids kufuneka adityaniswe kunye ne-8 # iingcingo zentsimbi nganye kwimitha eyi-1 ecaleni kwendlela ethe tye yendlela, kwaye ibekwe kwii-geogrids ezibekiwe.Lungisa emhlabeni ngee-U-zikhonkwane rhoqo nge-1.5-2m.
4. Emva kokuba umaleko wokuqala we-geogrid ubekwe, umaleko wesibini we-0.2m ophakathi, orhabaxa, kunye nesanti uyazaliswa.Indlela yokuthuthwa kwesanti isiwe kwindawo yokwakha ize iyothule kwelinye icala lendlela, emva koko usebenzise ibulldozer ukutyhala phambili.Okokuqala, gcwalisa i-0.1m phakathi koluhlu lweemitha ezi-2 kumacala omabini omandlalo wendlela, emva koko ugobe umaleko wokuqala we-geogrid uze uwugcwalise nge-0.1m yokuphakathi, erhabaxa, kunye nesanti.Ukuthintela ukuzaliswa kunye nokutyhala ukusuka kumacala omabini ukuya embindini, kwaye uthintele oomatshini abahlukeneyo ukuba badlule kwaye basebenze kwi-geogrid ngaphandle kokuzalisa, ukurhabaxa kunye nesanti.Oku kunokuqinisekisa ukuba i-geogrid ithe tyaba, ayidubuleki, okanye ishwabene, kwaye ilinde umaleko wesibini ophakathi, orhabaxa, kunye nesanti ukuba ulungelelaniswe.Umlinganiselo othe tyaba kufuneka uqhutywe ukunqanda ukungalingani kokuzalisa ubukhulu.Emva kokulinganisa ngaphandle kweempazamo, i-25T i-vibrating roller kufuneka isetyenziswe kwi-static pressure kabini.
5. Indlela yokwakha yoluhlu lwesibini lwe-geogrid iyafana neyokuqala.Ekugqibeleni, gcwalisa i-0.3m ye-medium, i-coarse, kunye nesanti ngendlela efanayo yokuzalisa njengomaleko wokuqala.Emva kweepaseji ezimbini zoxinzelelo lwe-static kunye ne-roller ye-25T, ukuqiniswa kwesiseko se-roadbed kugqityiwe.
6. Emva kokuba umaleko wesithathu we-medium, coarse, kunye nesanti idityanisiwe, ii-geogrids ezimbini zibekwe ngobude ecaleni komgca kumacala omabini ethambeka, zigqithe nge-0.16m, kwaye ziqhagamshelwe kusetyenziswa indlela efanayo ngaphambi kokuqala umsebenzi wokwakha umhlaba.Beka i-geogrids ukwenzela ukhuseleko lwethambeka.Imigca yomphetho ebekiweyo kufuneka ilinganiswe kwinqanaba ngalinye.Icala ngalinye kufuneka liqinisekise ukuba i-geogrid ingcwatywe ngaphakathi kwe-0.10m yethambeka emva kokulungiswa kwethambeka.
7. Xa uzalisa iileya ezimbini zomhlaba ezinobunzima obuyi-0.8m, i-geogrid kufuneka ibekwe kumacala omabini ethambeka ngaxeshanye.Emva koko, njalo njalo, ide ibekwe phantsi komhlaba phezu kwegxalaba lendlela.
8. Emva kokuba i-roadbed izaliswe, i-slope kufuneka ilungiswe ngexesha elifanelekileyo.Kwaye unikeze ukhuseleko lwenkunkuma eyomileyo emazantsi ethambeka.Ukongeza ekwandiseni icala ngalinye nge-0.3m, indawo yokuhlala ye-1.5% nayo igcinelwe eli candelo lendlela.
