Dị ka ihe a na-ejikarị arụ ọrụ okporo ụzọ, geogrids na-ekere òkè dị mkpa n'iwu okporo ụzọ.N'otu oge ahụ, geogrids na-ekewa n'ime ụdị dị iche iche.Taa, anyị ga-ewebata ọrụ nke ụdị geogrids dị iche iche.
Enwere ụdị geogrids anọ.Ka anyị webata ha:
1. Unidirectional plastic geogrid ọrụ:
Uniaxial tensile geogrid bụ ihe geosynthetic siri ike dị elu.A na-ejikarị ya eme ihe na embankment, ọwara, wharf, okporo ụzọ, ụgbọ okporo ígwè, ihe owuwu na ubi ndị ọzọ.Isi ihe eji eme ya bụ ndị a: mee ka subgrade dị ike, kesaa ibu mgbasa nke ọma, kwalite nkwụsi ike na ikike ibu nke subgrade, na ịgbatị ndụ ọrụ.Ọ nwere ike idi ibu ọzọ ọzọ.Gbochie nrụrụ subgrade na mgbawa nke ihe mfu nke subgrade kpatara kpatara.Ọ nwere ike imeziwanye ikike ijide onwe ya nke njuputa n'azụ mgbidi ahụ, belata nrụgide ụwa nke mgbidi na-ejigide, chekwaa ego, ịgbatị ndụ ọrụ, ma belata ụgwọ ọrụ.Ejikọtara ya na usoro ihe owuwu nke shotcrete na arịlịka, mmezi mkpọda nwere ike ọ bụghị naanị ịchekwa 30% - 50% nke itinye ego, kamakwa belata oge owuwu ihe karịrị ugboro abụọ.Ịgbakwunye geogrids na subgrade na elu oyi akwa nke okporo ụzọ awara awara nwere ike ibelata mgbagha, belata rutting, na-egbu oge oge mgbawa site na ugboro 3-9, ma belata ọkpụrụkpụ nke oyi akwa ahụ site na 36%.Ọ na-adabara maka ụdị ala ọ bụla, na-enweghị ihe ndị sitere na ebe ndị ọzọ, na-echekwa ọrụ na oge.Ihe owuwu ahụ dị mfe na ngwa ngwa, nke nwere ike belata ọnụ ahịa ihe owuwu.Mgbakwunye njikọ nke geogrid, mmesi obi ike.

2. Ọrụ nke geogrid plastic ụzọ abụọ:
Na-abawanye ikike ibu nke okporo ụzọ (ala) ntọala na ogologo ndụ ọrụ nke okporo ụzọ (ala) ntọala.Gbochie ndakpọ ma ọ bụ mgbawa nke elu ụzọ (ala) ma mee ka ala mara mma ma dị mma.Ihe owuwu dị mma, na-echekwa oge, na-echekwa ọrụ, na-ebelata oge owuwu ma belata ụgwọ ọrụ.Gbochie eriri mmiri ahụ ịgbawa.Mee ka mkpọda ala dị ike ma gbochie mmiri na mfu ala.Belata ọkpụrụkpụ nke ihe nkuku ma chekwaa ọnụ ahịa ya.Na-akwado ebe ahịhịa ndụ kwụsiri ike nke ihe ọkụkụ na-akụ ahịhịa na mkpọda.Ọ nwere ike dochie ntupu ígwè ma jiri ya mee ntupu ụlọ ụgha na-egwupụta coal.
3. Ọrụ nke ígwè-plastic geogrid:
A na-ejikarị ya n'ọhịa nke nkwado ntọala ala dị nro, na-ejigide mgbidi na pavement crack resistance engineering nke okporo ụzọ okporo ụzọ, ụgbọ okporo ígwè, abutments, ịbịaru nso, wharves, revetments, dams, slag yards, wdg.
4. Ọrụ nke glass fiber geogrid:
A na-eme ka pavmenti kọnkịta nke ochie mesie ike iji mee ka elu asphalt sie ike ma gbochie ọrịa.A na-arụgharị pavement simenti ka ọ bụrụ pavement nwere ngwakọta iji gbochie mgbawa ntụgharị uche nke mbelata efere efere kpatara.Mgbasawanye na nrụgharị okporo ụzọ na-arụ ọrụ, na-egbochi mgbawa nke ọhụụ ọhụrụ na nke ochie na nhazi na-enweghị isi kpatara.Ngwọta nkwado nke ntọala ala dị nro na-eme ka nkewa mmiri na ịkwado ala dị nro, na-egbochi nhazi nke ọma, nkesa nrụgide otu, na ịkwalite ike zuru oke nke subgrade.Oghere siri ike nke okporo ụzọ ọhụrụ ahụ na-emepụta mgbawa shrinkage, na mgbakwunye na-eme ka a na-eme ka ọkpụkpụ pavement na-eme ka ọ bụrụ ihe ngosi nke mgbawa ntọala.

2. Olee otú mma bụ mgbochi ike ọgwụgwụ cracking arụmọrụ nke geogrid
Geogrid na-eji eriri polyester siri ike ma ọ bụ eriri polypropylene dị ka akụrụngwa, na-anabata usoro ntụzịaka nke warp, na warp na weft yarn na akwa ahụ enweghị ike ịgbagọ, a na-ejikọkwa njikọ ahụ ma jikọta ya na fiber filament siri ike na-etolite. siri ike njide ebe, na-enye zuru play ya n'ibu Njirimara.Ya mere, ị maara otú mma ike ọgwụgwụ mgbawa mgbawa bụ?
Mmetụta dị ukwuu nke mkpuchi asphalt na pavement simenti ochie bụ imeziwanye ọrụ ntinye nke pavement, ma ọ nwere obere ihe na-enye aka na-ebute mmetụta.Pavement siri ike nke dị n'okpuru ihe mkpuchi ahụ ka na-enwe mmetụta dị oke mkpa.Ihe mkpuchi asphalt dị na pavement asphalt ochie dị iche.Ihe mkpuchi nke asphalt ga-ebu ibu ya na pavement asphalt ochie.Ya mere, ihe mkpuchi asphalt na pavement nke asphalt ga-egosi na ọ bụghị nanị na-egosi mgbawa ntụgharị, ma na-egosipụtakwa ike ọgwụgwụ n'ihi mmetụta dị ogologo oge nke ibu ahụ.Ka anyị nyochaa ọnọdụ ntinye nke asphalt machie na pavement ochie nke asphalt: n'ihi na ihe mkpuchi nke asphalt bụ oyi akwa na-agbanwe agbanwe nke nwere otu ihe onwunwe dị ka ihe mkpuchi nke asphalt, mgbe etinyere ya na mmetụta ibu ahụ, pavement ga-enwe ntụgharị.Ihe mkpuchi asphalt nke na-emetụ wiil ahụ ozugbo nọ n'okpuru nrụgide, na elu na-adabere na ike nkwụsị na mpaghara dị n'akụkụ oke ibu wheel.N'ihi na ihe ndị dị ike nke mpaghara abụọ ahụ na-akpata nchekasị dị iche iche na nso ibe ha, ọ dị mfe imebi na nkwụsị nke mpaghara abụọ ahụ, ya bụ mgbanwe mberede nke ike.N'okpuru mmetụta nke ibu ogologo oge, ike ọgwụgwụ na-eme.
Geogrid nwere ike gbasasịa nrụgide mkpakọ dị n'elu na nrụgide tensile na asphalt overlay iji mepụta mpaghara nchekwa n'etiti mpaghara nrụgide abụọ ahụ, ebe nrụgide na-agbanwe nwayọ nwayọ karịa na mberede, na-ebelata mmebi nke nrụgide mgbanwe mberede na mkpuchi asphalt.Obere elongation nke iko fiber geogrid na-ebelata nkwụsị nke pavement ma hụ na pavement agaghị enwe ngbanwe mgbanwe.
A na-eji polymer (polypropylene PP ma ọ bụ polyethylene HDPE wepụ ya n'ime mpempe akwụkwọ dị mkpa), wee tụba ya n'ime netwọk oghere mgbe niile, wee gbatịa ogologo oge.N'ime usoro a, polymer nọ n'ọnọdụ kwụ ọtọ, na-eme usoro netwọk ogologo elliptical nwere nkesa otu na ike ọnụ elu.
grid Unidirectional bụ ụdị ihe geosynthetic siri ike dị elu, nke enwere ike kewaa n'ime grid polypropylene unidirectional na grid polyethylene unidirectional.
Uniaxial tensile geogrid bụ ụdị geotextile siri ike nke nwere polymer dị elu dị ka isi akụrụngwa, agbakwunyere ya na ụfọdụ ihe mgbochi ultraviolet na mgbochi ịka nká.Mgbe esemokwu uniaxial gachara, a na-atụgharịgharị mkpụrụ ndụ yinye ndị mbụ ekesara gaa n'ọnọdụ kwụ ọtọ, wee tụba ya n'ime efere dị mkpa, na-emetụta ntupu a na-ahụkarị, wee gbatịa ogologo oge.Sayensị ihe onwunwe.
N'ime usoro a, a na-eduzi polymer site na steeti linear, na-eme usoro netwọk ogologo elliptical na nkesa otu na ike ọnụ elu.Ihe owuwu a nwere nnukwu ike ike na modul.Ike ike bụ 100-200Mpa, nke dị nso na ọkwa nke obere carbon steel, ma dị mma karịa ihe nkwado ọdịnala ma ọ bụ dị adị.
Karịsịa, ngwaahịa a nwere ọkwa mba ụwa n'oge dị oke elu (mgbatị nke 2% - 5%) ike ntakiri na modul.Ọ na-enye usoro dị mma maka ntinye ala na mgbasa.Ngwaahịa a nwere nnukwu ike ike (> 150Mpa) ma dabara maka ụdị ala ọ bụla.Ọ bụ ihe agbamume a na-ejikarị eme ihe ugbu a.Njirimara ya bụ isi bụ ike dị elu, arụmọrụ dị mma, ihe owuwu dị mma na ọnụ ala dị ala.
