1. Asphalt impregnation ọgwụgwọ n'elu nrụgide mmetụta nrapado nke geogrid
A na-agbanye elu geogrid na nrapado nke na-ejide onwe ya iji chịkwaa geogrid. Asphalt gbanyere mkpọrọgwụ nrapado na-enwe mmetụta na-emetụ n'ahụ n'elu geogrid bụ ihe geosynthetic bụ isi nke geogrid. Tụnyere geosynthetics ndị ọzọ, HDPE geomembrane na-egosi n'ụzọ zuru ezu izi ezi na arụmọrụ ya. A na-ejikarị Geogrid eme ihe dị ka ihe nkwado nke nhazi ụwa ma ọ bụ ihe nkwado nke aluminum alloy geotextile emeputa.

A na-ekewa Geogrid ụzọ anọ: plastic geogrid, metal-plastic geogrid, glass fiber geogrid na glass fiber polyester geogrid. Plastic geogrid bụ ihe netwọk polymer zuru oke nwere akụkụ anọ ma ọ bụ akụkụ anọ etolite site na ịkwa akwa na-aga n'ihu. Dị ka nkwụsi ike nke ntụziaka extrusion n'oge usoro nnomi, enwere ike kewaa ya n'ụdị abụọ: otu ụzọ na-agbapụ na ụzọ abụọ.
Ọ bụ ịkụtu oghere n'ụfọdụ efere polymer nke extrusion na-emetụta, wee kwaga n'ihu mgbatị ntụzịaka n'okpuru ebe jụrụ oyi. Mgbe mgbawa nke geotextile ruru 10% nke mpịakọta mpịakọta, anyị kwesịrị ịrụ ọrụ akụkụ ahụ mebiri emebi, wee jikọta ebili mmiri abụọ ahụ nke ọma. Na mgbakwunye, ọ bụrụ na ọdịiche dị n'elu mkpọda ahụ ruru 10% nke mpịakọta mpịakọta, a ga-ewepụ akwụkwọ mpịakọta geotextile ma jiri mpịakọta ọhụrụ dochie ya. Ihe mkpuchi nke geogrid geomembrane na-emepụta ihe na-eme n'oge usoro ọgwụgwọ na-adabere na onye na-emepụta ihe mejupụtara asphalt.
A na-ekpuchi eriri ọ bụla kpamkpam ma kwekọọ n'ụzọ zuru ezu na asphalt, iji hụ na a gaghị ebipụ iko fiber geogrid na oyi akwa nke asphalt na ihe mejupụtara nke asphalt, ma jikọta ya. A ga-edobe geogrid n'elu oyi akwa dị nro dị ala dịka nha nke akwadoro siri dị. Ihe ndochi nke usoro mgbago elu agaghị adụpu irighiri ihe nke geogrid. Mgbe etinyere geogrid, ikuku na-agba ọsọ dị oke elu iji gafee etiti etiti nke embankment. A na-edobe Geogrid ogologo oge. A ga-emesi nkedo ahụ ike ka ọ ghara ịhịa aka n'ahụ, ntụgharị ma ọ bụ olulu.
A na-ejikọta geogrid n'ahịrị site na usoro nkpuchi, na nha ịnya ụgbọ ala adịghị agafe 20cm. Mgbe etinyechara geogrid, a ga-emecha ntinye akwụkwọ ntuziaka nke ihe mkpuchi elu elu ozugbo iji gbochie ikpughe anyanwụ n'afọ niile. Mgbe ahụ, mee njem ụgbọ njem ihe eji arụ ọrụ, nhazi na ntụgharị. A na-esi n'akụkụ abụọ ahụ na-emegharị ihe na-arụ ọrụ na-emegharị ihe na-eme ka ọ bụrụ akụkụ abụọ, a na-eme ka ọkpụkpụ ahụ site n'akụkụ abụọ gaa n'akụkụ abụọ, a na-echekwa kọmpat iji nweta mkpochapụ ọkọlọtọ.
2, Geogrid nwere tensile ike nke nwayọọ ígwè
Geogrid na-ahazi molekul hydrocarbon ogologo nke polymer n'ahịrị kwụ ọtọ n'akụkụ ụzọ mgbatị ahụ site na usoro teknụzụ pụrụ iche. A na-emesi ike ike nke dị n'etiti ụdọ molekụla nke ukwuu, n'ihi ya, ọ nwere ike ike dị elu na elongation dị ala. Dịka ọmụmaatụ, ike nkwụsị ahụ dị 5-10 ugboro karịa nke ahụ tupu ịgbatị, na elongation bụ naanị 10% - 15% karịa nke ahụ tupu ịgbatị. The interlocking ike nke ụmụ irighiri ihe na okporo na-abawanye, na esemokwu esemokwu na-abawanye nke ukwuu. Enwere ike ikwu na n'etiti ọtụtụ geosynthetics, ike ike nke geogrid bụ nke kachasị elu n'okpuru otu ụdị ahụ, na ike ike ya dị nso na nke ígwè dị nro. Na mgbakwunye na ike ike ya siri ike, geogrid nwekwara ịdịte aka dị mma, n'ihi na ihe geogrid bụ nke polyethylene dị elu ma ọ bụ polypropylene plastic dị ka isi ihe, ma nwee ihe mgbakwunye mgbochi ịka nká dị ka UV na carbon black, nke nwere ike. gbochie mmebi nke ihe mgbaze organic dị ka acid, alkali, nnu, mmanya, mmanụ ụgbọala na UV. Dabere na data dị mkpa, ndụ ọrụ geogrid nke ndị na-emepụta geogrid na-emepụta nwere ike iru afọ 120 n'okpuru ọnọdụ okpomọkụ nkịtị na imepụta ibu ikike. N'ezie, ihe kpatara eji eji geogrids eme ihe bụ na geogrids akọwara n'okpuru nwere àgwà magburu onwe ya. N'ime ọrụ ịchọ mma mkpọda, plastic geocell nke onye na-emepụta geogrid, mgbe geocell agbatịchara ma meghee ya, na-ewepụta geocell nwere akụkụ atọ nwere mmanụ aṅụ, wee jupụta geocell na ụwa na nkume ma ọ bụ ihe ndị siri ike iji mepụta ihe owuwu nwere njide mpụta siri ike. nnukwu isi ike na-etolite mmetụta nkwụsi ike na mkpọda. Ọ nwekwara ike ịzụlite ụfọdụ ahịhịa, ma ọ bụ obere osisi na osisi ndị ọzọ na geogrid, na-akpụ ihe na-abụghị iko fiber grid bụ isi geosynthetic ihe, nke nwere otu arụmọrụ na mmetụta tụnyere ndị ọzọ geosynthetic ihe. A na-ejikarị eriri enyo enyo mee ihe dị ka nkwado maka ihe owuwu ala siri ike ma ọ bụ ihe mejupụtara
