Ukuhamba kwenkqubo yokwakha:
Ulungiselelo lolwakhiwo (uthutho lwempahla kunye nokubekwa phandle) → unyango olusisiseko (ukucoca) → ukubekeka kwe-geogrid (indlela yokubeka nobubanzi obuthe kratya) → isihluzi (indlela kunye nobukhulu bamasuntswana) → igridi yokuqengqeleka → ukubekeka kwegridi esezantsi.
Indlela yokwakha:
① Unyango olusisiseko
Okokuqala, umaleko ongezantsi uya kunyuswa kwaye usongwe.Umcaba awuyi kuba mkhulu kune-15mm, kwaye ukuxinana kuya kuhlangabezana neemfuno zoyilo.Umphezulu uya kukhululeka kwiiprotrusions eziqinileyo ezifana negrabile kunye nelitye lebhloko.
② Ukubekwa kweGeogrid
A. Xa ugcina kwaye ubeka i-geogrid, kuphephe ukuba sesichengeni elangeni kunye nokuba sesichengeni ixesha elide ukuthintela ukuwohloka kokusebenza.
b.Ukubekwa kuya kuba yi-perpendicular ukuya kumgca womgca, ukukhwela kuya kuhlangabezana neemfuno zemizobo yoyilo, kwaye uxhulumaniso luya kuqina.Amandla okudibanisa kwindlela yoxinzelelo akayi kuba ngaphantsi koyilo lwamandla obunzima bezinto eziphathekayo, kwaye ubude obunqamlekileyo abuyi kuba ngaphantsi kwe-20 cm.
c.Umgangatho we-geogrid uya kuhlangabezana neemfuno zemizobo yoyilo.
d.Ulwakhiwo luya kuqhubeka ngaphandle kokuphazamiseka, ukushwabana kunye nokudlulana.Igridi iya kunyanzelwa ukwenza ukuba ithwale amandla.Igridi iya kunyanzeliswa ngesandla ukuze ifane, isicaba kwaye isondele kumphezulu wokuthwala ongezantsi.Igridi iya kulungiswa ngezikhonkwane kunye neminye imilinganiselo.
e.Kwi-geogrid, isalathiso somngxuma omde siya kuhambelana nolwalathiso lwecandelo lomnqamlezo womgca, kwaye i-geogrid iya kulungiswa kwaye ilinganiswe.Isiphelo segrayiti siya kuphathwa ngokuhambelana noyilo.
f.Gcwalisa i-geogrid ngexesha emva kokuhamba ngeenyawo, kwaye ikhefu aliyi kudlula i-48h ukuphepha ukuchanabeka ngokuthe ngqo elangeni.
③ Isifaki
Emva kokuba igrayiti igayiwe, iya kuzaliswa ngexesha.Ukuzaliswa kuya kuqhutywa ngokulinganayo ngokomgaqo othi "amacala amabini kuqala, emva koko phakathi".Akuvumelekanga ngokungqongqo ukugcwalisa umbindi we-embankment kuqala.Isigcwalisi asivumelekanga ukuba sithulwe ngokuthe ngqo kwi-geogrid, kodwa kufuneka sithulwe kwindawo egangathiweyo yomhlaba, kwaye ukuphakama kokukhulula akukho ngaphezu kwe-1m.Zonke izithuthi kunye noomatshini bokwakha abayi kuhamba ngokuthe ngqo kwi-geogrid egangathiweyo, kodwa kuphela ecaleni kodonga.
④ Songa igrile
Emva kokuba umaleko wokuqala wokuzaliswa ufikelele kubukhulu obumiselweyo kwaye ugqitywe kwi-compact compactness, igridi iya kuphinda ibuyele umva kwi-2m kwaye iboshwe kwinqanaba langaphambili le-geogrid, kwaye i-geogrid iya kunqunyulwa ngesandla kwaye igxininiswe.Icala elingaphandle lesiphelo somqulu liya kufakwa ngasemva kwi-1m ukukhusela igridi kunye nokuthintela umonakalo owenziwe ngumntu.
⑤ Omnye umaleko we-geogrid uya kugaywa ngokwendlela engentla, kwaye ezinye iileya ze-geogrid ziya kugalelwa ngendlela efanayo.Emva kokuba igridi igalelwe, ukuzaliswa kwe-embankment ephezulu kuya kuqaliswa.
Izilumkiso zokwakha:
① Isalathiso samandla amakhulu egridi siya kuhambelana nesalathiso soxinzelelo olukhulu.
② Izithuthi ezinzima aziyi kuqhutywa ngokuthe ngqo kwi-geogrid egangathiweyo.
③ Isixa esisikiweyo nesixa sokuthunga se-geogrid siyakuncitshiswa ukunqanda inkcitho.
④ Ngexesha lokwakha ngamaxesha abandayo, i-geogrid iya kuba nzima, kwaye kulula ukusika izandla kunye nokusula amadolo.Nika ingqalelo ukhuseleko.
