I-Uniaxial geogrids, ikakhulukazi i-PP (i-polypropylene)i-uniaxial geogrids, ziyingxenye ebalulekile yamaphrojekthi wesimanje wobunjiniyela bomphakathi namaphrojekthi wokwakha. Lawa ma-geosynthetics aklanyelwe ukuhlinzeka ngokuqiniswa nokuzinzisa emisebenzini ehlukahlukene, okuhlanganisa ukwakhiwa komgwaqo, izindonga ezibambayo kanye nokuqiniswa kwenhlabathi. Ukuqonda amandlai-uniaxial geogridskubalulekile konjiniyela nabaqambi ukuze baqinisekise impilo ende nokusebenza ngempumelelo kwamaphrojekthi abo.
Ukubunjwa kanye nesakhiwo
I-PP uniaxial geogridyenziwe nge-high-density polypropylene, eyaziwa ngamandla ayo aqinile okuqina nokuqina. Inqubo yokukhiqiza ibandakanya ukukhipha i-polymer ibe isakhiwo esifana ne-mesh, ukudala uchungechunge lwezimbambo ezixhumene. Lo mklamo uvumela i-geogrid ukuthi isabalalise imithwalo endaweni enkulu, inciphise ingcindezi enhlabathini engaphansi noma ekuhlanganisweni. Ukucushwa kwe-uniaxial kusho ukuthi i-geogrid yakhelwe ngokuyinhloko ukuthi imelane namandla aqinile ohlangothini olulodwa, iyenze isebenze kahle ezinhlelweni zokusebenza lapho imithwalo isetshenziswa ngendlela yomugqa.
Izici zamandla
Amandla e-uniaxial geogrid ngokuvamile akalwa ngamandla ayo aqinile, okungamandla amakhulu aqinile (amandla okudonsa) okubalulekile okungamelana nawo ngaphambi kokuhluleka. Lesi sakhiwo sibalulekile ekunqumeni ukusebenza kwama-geogrid ngaphansi komthwalo. Amandla aqinile wei-polypropylene uniaxial geogridsiyahlukahluka kakhulu kuye ngomkhiqizo othize kanye nokusetshenziswa kwawo okuhlosiwe. Ngokuvamile, amandla aqinile alawa ma-geogrid asukela ku-20 kN/m kuya ngaphezu kuka-100 kN/m, kuye ngogqinsi nomklamo we-geogrid.
Ngokungeziwe emandleni aqinile, ezinye izici ezifana ne-elastic modulus kanye nobude ngesikhathi sekhefu nazo zibalulekile. I-elastic modulus ibonisa ukuthi i-geogrid ishintshashintsha kangakanani ngaphansi komthwalo, kuyilapho ukunwetshwa ngesikhathi sekhefu kunikeza ukuqonda kokuduka kwezinto. Ubude obuphakeme ngesikhathi sekhefu kusho ukuthi i-geogrid inganwebeka kakhulu ngaphambi kokwehluleka, okuzuzisa izinhlelo zokusebenza lapho ukunyakaza komhlaba kulindeleke.
Izicelo Nezinzuzo
Amandla wei-uniaxial geogridsibenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza. Ekwakhiweni komgwaqo, zivame ukusetshenziselwa ukuqinisa isendlalelo se-subgrade, ukuthuthukisa ukusatshalaliswa komthwalo kanye nokunciphisa ingozi yokuhluleka komgwaqo. Ekugcineni izinhlelo zokusebenza zodonga, i-uniaxial geogrid isiza ukuzinzisa inhlabathi futhi ivimbele ukunyakaza kwe-lateral, iqinisekisa ubuqotho besakhiwo.
Enye yezinzuzo eziyinhloko zokusebenzisaI-PP uniaxial geogridyikhono lokwenza ngcono ukusebenza jikelele kwesakhiwo somhlabathi. Ngokunikeza amandla engeziwe e-tensile, lawa ma-geogrid anganciphisa kakhulu ukuhlaliswa kanye nokuguqulwa, enze ingqalasizinda ihlale isikhathi eside futhi ithembeke kakhudlwana. Ukwengeza, imvelo yazo engasindi izenza kube lula ukuziphatha nokuzifaka, kunciphisa izindleko zabasebenzi kanye nesikhathi sokwakha.
Ekuphetheni
Kafushane, amandla ama-geogrid e-uniaxial, ikakhulukazi i-polypropylene uniaxial geogrids, ayisici esibalulekile ekusebenzeni kwawo njengezisetshenziswa zokuqinisa kuzinhlelo zokusebenza zobunjiniyela bomphakathi. Ngenxa yokuthi amandla e-tensile ayahluka kakhulu, onjiniyela kufanele bakhethe i-geogrid efanele ngokusekelwe ezidingweni ezithile zephrojekthi. Ngokuqonda izici zamandla nezinzuzo ze-uniaxial geogrids, ochwepheshe bangenza izinqumo ezinolwazi ezizothuthukisa ukuqina nokusebenza kwezakhiwo zabo. Njengoba isidingo sezinqubo zokwakha ezisimeme, ezisebenzayo ziqhubeka nokukhula, indima ye-uniaxial geogrids kubunjiniyela besimanje ngokungangabazeki izobaluleka kakhulu.
