1. Kalafo ea ho kenngoa ha asphalt holim'a sekhomaretsi se nang le khatello ea maikutlo sa geogrid
Sebaka sa geogrid se kentsoe ka sekhomaretsi se ikamahanyang le khatello ea maikutlo ho laola geogrid.Asphalt e kentsoeng ka sekhomaretsi se ikamahanyang le khatello ea maikutlo holim'a geogrid ke thepa ea mantlha ea geosynthetic ea geogrid.Ha ho bapisoa le li-geosynthetics tse ling, HDPE geomembrane e bontša ka botlalo bonnete ba eona le katleho ea eona.Geogrid e atisa ho sebelisoa e le thepa e matlafatsang ea mohaho oa lefats'e o matlafalitsoeng kapa thepa e matlafatsang ea moetsi oa aluminium alloy geotextile.

Geogrid e arotsoe ka mekhahlelo e mene: polasetiki geogrid, tšepe-polasetiki geogrid, khalase faeba geogrid le khalase fiber polyester geogrid.Plastic geogrid ke thepa ea netweke ea khutlonnetsepa kapa e khutlonnetsepa e entsoeng ka ho kuta ho tsoelang pele.Ho latela ho tsitsa ha tataiso ea extrusion nakong ea ts'ebetso ea kopi, e ka aroloa ka mefuta e 'meli: ho kuta ka tsela e le' ngoe le extrusion ea litsela tse peli.
Ke ho phunya masoba lipoleiting tse ling tsa polymer tse anngoeng ke extrusion, ebe o sutumelletsa pele tsela e otlolohileng tlas'a motheo oa pholileng.Ha ho phatloha ha geotextile ho fihla ho 10% ea boholo ba moqolo, re hloka ho sebetsa karolo e senyehileng, ebe re hokahanya maqhubu a mabeli a lefats'e haufi-ufi.Ho phaella moo, haeba lekhalo holim'a letsoapo le fihla ho 10% ea boholo ba moqolo, moqolo oa geotextile o lokela ho tlosoa ebe o nkeloa sebaka ke moqolo o mocha.Thepa ea ho roala e sebelisoang ke moetsi oa geogrid geomembrane ka mor'a phekolo e lebisitsoe ho moetsi oa thepa ea asphalt composite.
Fiber e 'ngoe le e' ngoe e koahetsoe ka ho feletseng 'me e lumellana ka ho feletseng le asphalt, e le ho etsa bonnete ba hore khalase ea fiber geogrid ka lera la asphalt e ke ke ea khaoloa ho tloha linthong tse entsoeng ka asphalt, empa e kopantsoe ka thata.Geogrid e tla behoa holim'a lera le bonolo le tlaase ho ea ka boholo ba thepa e lokisitsoeng.Motlatsi oa sebaka se kaholimo se ke ke sa phunya lithōle tsa geogrid.Ha geogrid e behiloe, lebelo la moea le phahame haholo ho tšela moeli o bohareng oa mokoloko.Geogrid e behiloe ka longitudinally.Lala le tla tiisetsoa ho thibela ho sosobana, ho sotha kapa ho sotha.
Geogrid e hokahane ka mokhoa o otlolohileng ka mokhoa o fetang, 'me boholo ba ho palama ha bo fete 20cm.Ka mor'a hore geogrid e behoe, ho behoa ka letsoho ha mochine o ka holimo ho tla phethoa hang-hang ho thibela ho pepesehela letsatsi selemo ho pota.Ebe u tsamaisa thepa ea mochini, ho lekanya le ho tsamaisa.Mechini ea ho penta le ho roala ho etsoa ho tloha mahlakoreng ka bobeli ho ea mahlakoreng ka bobeli, 'me ho roala ho etsoa ho tloha mahlakoreng ka bobeli ho ea mahlakoreng ka bobeli,' me ho boloka compactness ho finyella ho felisoa ho tloaelehileng.
2, Geogrid e na le matla a tsitsitseng a tšepe e bonolo
Geogrid e hlophisa bocha limolek'hule tsa ketane e telele ea hydrocarbon ea polymer ka tsela e otlolohileng ho latela tsela e otlolohileng ka mokhoa o ikhethileng oa theknoloji.Matla a tlamang pakeng tsa liketane tsa limolek'hule a matlafatsoa haholo, kahoo a na le matla a phahameng a ho tsitsa le bolelele bo tlaase.Ka mohlala, matla a matla a 5-10 ho feta pele a otlolla, 'me bolelele ke 10% - 15% feela ho feta pele ho otlolla.Matla a ho kopanya a likaroloana a marang-rang a eketseha, 'me coefficient ea likhohlano e eketseha haholo.Ho ka boleloa hore har'a li-geosynthetics tse ngata, matla a thata a geogrid ke a phahameng ka ho fetisisa tlas'a khatello e tšoanang, 'me matla a eona a thata a haufi le a tšepe e bonolo.Ntle le matla a eona a matla a matla, geogrid e boetse e na le nako e telele ea nako e telele, hobane thepa ea geogrid e entsoe ka polyethylene e phahameng haholo kapa polasetiki ea polypropylene e le thepa e ka sehloohong e tala, 'me e na le li-additives tse thibelang botsofali tse kang UV le carbon black, e ka khonang. thibela khoholeho ea lihlahisoa tse hlapollang tse kang acid, alkali, letsoai, joala, peterole le UV.Ho ea ka lintlha tse amehang, bophelo ba tšebeletso ea geogrid bo hlahisoang ke baetsi ba geogrid bo ka fihla lilemo tse 120 tlas'a maemo a tloaelehileng a mocheso le moralo o amohelehang.Ehlile, lebaka leo ka lona li-geogrids li sebelisoang haholo ke hore li-geogrids tse hlalositsoeng ka tlase li na le litšobotsi tse ntle haholo.Morerong oa ho khabisa matsoapo, geocell ea polasetiki ea moetsi oa geogrid, ka mor'a hore geocell e atolosoe le ho buloa, e hlahisa khekhe ea linotši ea mahlakore a mararo, 'me e tlatsa geocell ka mobu le majoe kapa lisebelisoa tsa konkreite ho etsa mohaho o nang le thibelo e matla ea lateral le boima bo boholo ho etsa phello ea botsitso letsoapong.E ka boela ea hlaolela limela tse ling, kapa lihlahla tse nyenyane le limela tse ling ho geogrid, ho etsa marang-rang a fapaneng a khalase ea fiber ke thepa e ka sehloohong ea geosynthetic, e nang le ts'ebetso le phello e tšoanang ha e bapisoa le lisebelisoa tse ling tsa geosynthetic.Hangata marang-rang a fiber ea khalase a sebelisoa e le matlafatso bakeng sa mehaho ea mobu e matlafalitsoeng kapa lisebelisoa tse kopantsoeng
