Inkqubo yokubeka i-Geogrid:
Hlola kwaye ucoce umaleko ongezantsi, beka i-geogridi ngezandla, bopha kwaye ulungise→gaba umhlaba ongaphantsi ongaphezulu→uqengqeleka→ukuhlola.
Izinto ekufuneka uziqwalasele xa ubeka i-geogrid:
(1) I-geogrid ibekwe kwiflethi ephantsi-ethwele umaleko ngokobubanzi obucwangcisiweyo.Umaleko ongentla wokugcwalisa awunayo inkunkuma enokuthi yonakalise i-geogrid.Xa ubeka i-geogrid, ulwalathiso lwamandla aphezulu kufuneka lube yi-perpendicular kwi-axis ye-embankment.uyilo.I-geogrid ibekwe ngokuthe tye.Qinisa kwaye wolule xa ubeka ukuthintela imibimbi, ukonakala okanye imingxuma.Ii-geogrids zicolwa ngobude kusetyenziswa indlela edityanisiweyo, kwaye ububanzi obudlulanayo abukho ngaphantsi kwe-20cm.
(2) Emva kokubeka i-geogrid, beka ngesandla umaleko ophezulu wokugcwalisa kwaye uphelise ukuqengqeleka kwangethuba ukuze uthintele ukuvela kwelanga ixesha elide.Emva koko sebenzisa ukuthutha ngoomatshini, ukulinganisa kunye nokuqengqeleka.I-Mechanical paving and rolling yenziwa ukusuka kwiziphelo zombini ukuya kwiziko, kwaye ukuqengqeleka kuqhutywa ukusuka kwiziphelo zombini ukuya kwiziko, kwaye idigri yokudibanisa igcinwa ukuze ihlangabezane neemfuno ezisemgangathweni.
(3) Thintela zonke izithuthi zokwakha kunye noomatshini bokwakha ekuhambeni okanye ukupakisha kwi-geogrid egangathiweyo.Jonga umgangatho we-geogrid nangaliphi na ixesha ngexesha lokwakha.Ukuba kukho nawuphi na umonakalo onjengokophuka, ukugqobhoza, okanye ukukrazuka, wulungise ngokomlinganiselo.okanye buyisela.
Indlela yolwakhiwo lweGeogrid:
(1) Okokuqala, yandlala ngokuchanekileyo umgca wethambeka lendlela.Ukuze kuqinisekiswe ububanzi bendlela, icala ngalinye liyandiswa nge-0.5m.Emva kokulinganisa umhlaba osisiseko ovezwayo, sebenzisa i-25T i-vibratory roller ukuyicinezela kabini, kwaye usebenzise i-50T i-vibratory roller ukuyicinezela kane., ukungalingani kwentsebenziswano yendawo eyenziweyo.
(2) Beka isanti eyi-0.3M engqindilili (erhabaxa) yesanti, kwaye emva kokulinganisa ngoomatshini bokusebenzisana, sebenzisa i-25T ye-vibratory roller ukwenza uxinzelelo lwe-static kabini.
(3) Lay geogrid.Xa ubeka i-geogrids, umgangatho ophantsi kufuneka ube tyaba kwaye uxinene.Ngokuqhelekileyo, kufuneka zibekwe phantsi, zilungelelaniswe, kwaye zingapakishwa.Akufunekanga zijikwe okanye zijikwe.Iigeogridi ezimbini ezimeleneyo kufuneka zidibane nge-0.2m, kwaye i-geogrids kufuneka idityaniswe ngokunqamlezayo ecaleni kwendlela.Amacandelo adibanisayo axhunywe kunye neNombolo ye-8 yocingo lwentsimbi nganye kwimitha eyi-1, kwaye igridi ebekiweyo igxininiswe phantsi kunye nezikhonkwane ze-U rhoqo kwi-1.5-2m.
4Indlela yile: ukuthutha isanti ukuya kwindawo yokwakha ngemoto kwaye uyothule ecaleni kwendlela, uze uyityhale phambili ngebulldozer., qala ugcwalise i-0.1m ngaphakathi kweemitha ezi-2 kuzo zombini iziphelo zendlela yendlela, usonge umaleko wokuqala we-geogrid, uze uwugcwalise nge-0.1m yesanti ephakathi (erhabaxa).Akuvumelekanga ukugcwalisa kunye nokutyhala iziphelo zombini ukuya embindini, kwaye zonke iintlobo zoomatshini azivumelekanga.Xa usebenza kwi-geogrid engazange izaliswe yisanti ephakathi (erhabaxa), oku kuya kuqinisekisa ukuba i-geogrid icaba, i-bulging, kwaye ayinamibimbi.Emva kokuba umaleko wesibini wesanti ephakathi (erhabaxa) isicaba, kufuneka kwenziwe umlinganiselo othe tyaba.Ukuthintela ukungalingani kokuzaliswa kobunzima, sebenzisa i-roller ye-vibratory ye-25T ukuze uyicinezele ngokukhawuleza kabini emva kokuba ilinganiswe.
(5) Indlela yokwakha yomaleko wesibini we-geogrid iyafana neyokuqala.Ekugqibeleni, yigcwalise nge-0.3M yesanti ephakathi (erhabaxa).Indlela yokuzalisa iyafana neyokuqala.Emva koxinzelelo lwe-static kabini nge-roller ye-25T, njengale Ukuqiniswa kwesiseko se-roadbed kugqityiwe.
(6) Emva kokuba umaleko wesithathu wesanti ephakathi (erhabaxa) uqengqiwe, beka iigeogrid ezimbini kuzo zozibini iziphelo zethambeka ngobude ecaleni komgca, ugqithe nge-0.16m, kwaye uzidibanise ngendlela efanayo, emva koko uqalise ukwakhiwa komhlaba.Xa ubeka i-geogrids yokukhusela i-slope, kuyimfuneko ukulinganisa imigca yecala ngalinye, kwaye uqinisekise ukuba i-geogrids ingcwatywe kwi-0.10m kwi-slope emva kokulungiswa kwe-slope kwicala ngalinye.
7 igxalaba lendlela.
(8) Emva kokuba i-roadbed izaliswe, ithambeka kufuneka lilungiswe kwangethuba, kwaye ukhuseleko lwenkunkuma eyomileyo kufuneka lwenziwe emazantsi ethambeka.Ukongeza ekwandiseni i-roadbed nge-0.3M kwicala ngalinye, i-1.5% yendawo yokuhlala kufuneka igcinwe.
