Geogrid ea tšepe-polasetiki
Tlhaloso e Khutšoanyane:
Geogrid ya tshepe – polasetiki e nka dithapo tsa tshepe tse matla haholo (kapa difaeba tse ding) e le moralo wa motheo wa kgatello – wa ho jara. Kamora kalafo e ikgethang, e kopanngwa le dipolasetiki tse kang polyethylene (PE) kapa polypropylene (PP) le di-additives tse ding, mme moqhaka o kopaneng wa matla a maholo – wa ho kgwesa o bopjwa ka tshebetso ya ho ntsha. Bokahodimo ba moqhaka hangata bo na le dipaterone tse kgabisitsweng tse sa hlakang. Moqhaka o mong le o mong o lohuwa kapa o tlangwa ka bolelele le ka ho parola sebakeng se itseng, mme manonyeletso a weldwa ka theknoloji e ikgethang ya ho tlamahana le ho kopanya ho fihlela qetellong ho bopa geogrid ya tshepe – polasetiki.
Litšobotsi le Tshebetso
Matla a phahameng le ho thekesela ho tlase: Matla a ho thaepa a jarwa ke lithapo tsa tšepe tse matla tse lohiloeng ka bolelele le ka ho thibana. E ka hlahisa modulus e matla haholo ea ho thaepa tlas'a maemo a khatello e tlase. Lithapo tsa tšepe tsa likhopo tse telele le tse thibanang li lohiloe ka letlooa, 'me lera la ho phuthela le ka ntle le thehoa ka mohato o le mong. Lithapo tsa tšepe le lera la ho phuthela le ka ntle li sebetsa ka ho hokahana, 'me sekhahla sa ho lelefatsa ho robeha se tlase haholo, eseng ho feta 3%. Ho thekesela ha lithapo tsa tšepe, e leng li-unit tse kholo tsa ho jara khatello, ho tlase haholo.
Koefficient e phahameng ea khohlano: Ka ho phekola bokaholimo ba polasetiki nakong ea ts'ebetso ea tlhahiso le ho hatella mekhoa e mebe, ho se tsitse ha bokaholimo ba geogrid ho ka ntlafatsoa, ho eketsa haholo koefficient ea khohlano pakeng tsa geogrid ea tšepe - polasetiki le mobu, le ho matlafatsa ka katleho phello ea ho hokahana ha geogrid mobung.
Bophara - bophara, bokgoni bo phahameng le theko e tlase: Bophara bo ka fihla ho 6m. Ditshebedisong tsa boenjiniere, e ka fihlella ditlamorao tse phahameng tsa bokgoni le theko e tlase tsa matlafatso, ya fokotsa di-rotation tsa kaho, ya ntlafatsa bokgoni ba kaho, le ditjeo tse tlase tsa kaho.
Ho hanyetsa mafome ka matla: Tšebeliso ea thepa e kang polyethylene e nang le bongata bo phahameng e netefatsa hore e ke ke ea senyeha ke litharollo tsa asiti le letsoai, oli mochesong oa kamore, leha e le hore e tla angoa ke ho qhibiliha ha metsi kapa tlhaselo ea likokoana-hloko. Ka nako e ts'oanang, e ka hanela botsofali bo bakoang ke mahlaseli a ultraviolet.
Kaho e bonolo: E bobebe, e bonolo ho e jara le ho e beha, 'me ts'ebetso ea kaho e bonolo ebile e potlakile. E ka sebelisoa hammoho le li-geosynthetics tse ling.
Masimo a Kopo
Boenjiniere ba litsela: E sebelisetsoa ho matlafatsa litsela tse ka tlase le tsa terene. E ka aba le ho hasanya mojaro ka katleho, ea ntlafatsa botsitso le bokhoni ba ho jara ba subgrade, ea eketsa bophelo ba ts'ebeletso ea tsela, ea fokotsa ho fetoha le ho petsoha ha subgrade, ea fokotsa ho fapoha, ea fokotsa ho kheloha, le ho liehisa nako ea ho hlaha ha mapetso.
Merero ea paballo ea metsi: E ka sebelisoa matamong a matamo a metsi, lithapo tsa taolo ea likhohola, matamo, kalafo ea lebōpo, jj., ho ntlafatsa botsitso ba matamo, ho thibela khoholeho ea mobu le ho fetoha ha letamo.
Boenjiniere ba kou: Mererong e kang mabopo le meaho, e ka ntlafatsa bokgoni ba ho jara motheo, ya hanela ho hohlolwa le ho kgohlopolwa ha matla a kantle a kang maqhubu a lewatle, mme ya netefatsa polokeho ya dibaka tsa kou.
Boenjiniere ba kaho: E sebelisetsoa ho matlafatsa motheo oa mobu o bonolo, ho sireletsa mabota, tšireletso ea leralla, jj. E ka ntlafatsa bokhoni ba mobu ba ho itjara, ea fokotsa khatello ea lefats'e ea lebota la ho sireletsa, le ho boloka litšenyehelo tsa projeke.
Masimo a mang: E ka boela ea sebelisoa boenjiniere ba sechaba joalo ka boema-fofane, mabala a lipapali, mabala a thepa, mabala a litšila, le mehaho e mosa ho tikoloho, e bapala karolo e kang ho matlafatsa le ho sireletsa.
