Uniaxial geogrids, ngakumbi PP (polypropylene)i-uniaxial geogrids, ziyinxalenye ebalulekileyo yobunjineli banamhlanje kunye neeprojekthi zokwakha. Ezi geosynthetics ziyilelwe ukubonelela ngokuqiniswa nokuzinzisa kwizicelo ezahlukeneyo, kubandakanywa ukwakhiwa kweendlela, ukugcinwa kweendonga kunye nokuzinzisa umhlaba. Ukuqonda amandla ei-uniaxial geogridsibaluleke kakhulu kwiinjineli kunye nabayili ukuze baqinisekise ubomi obude kunye nokusebenza kakuhle kweeprojekthi zabo.
Ukuqulunqwa kunye nesakhiwo
PP uniaxial geogridyenziwe ngepolypropylene yoxinaniso oluphezulu, eyaziwa ngamandla ayo okuqina kunye nokuqina. Inkqubo yokuvelisa ibandakanya ukukhupha i-polymer kwisakhiwo esifana ne-mesh, ukudala uluhlu lweembambo ezidibeneyo. Olu yilo luvumela i-geogrid ukuba isasaze imithwalo kwindawo enkulu, inciphisa uxinzelelo kumhlaba ongaphantsi okanye i-aggregate. Uqwalaselo lwe-uniaxial luthetha ukuba i-geogrid iyilelwe ikakhulu ukuxhathisa amandla e-tensile kwicala elinye, iyenza isebenze ngokukodwa kwizicelo apho imithwalo ifakwa ngendlela elandelelanayo.
Iimpawu zamandla
Amandla e-uniaxial geogrid ngokuqhelekileyo alinganiswa ngamandla ayo okuqina, angawona mandla obunzima obukhulu (amandla okutsala) into enokumelana phambi kokusilela. Le propati ibalulekile ekumiseleni ukusebenza kwee-geogrids phantsi komthwalo. Ukomelela kwepolypropylene uniaxial geogridsiyahluka ngokubanzi ngokuxhomekeke kwimveliso ethile kunye nokusetyenziswa kwayo. Ngokubanzi, amandla okuqina kwezi geogrids asuka kwi-20 kN/m ukuya ngaphezulu kwe-100 kN/m, kuxhomekeke kubukhulu kunye noyilo lwegeogrid.
Ukongeza kumandla okuqina, ezinye izinto ezinje nge-elastic modulus kunye nobude ngexesha lekhefu nazo zibalulekile. I-elastic modulus ibonisa ukuba i-geogrid ikhubaza kangakanani phantsi komthwalo, ngelixa i-elongation ngexesha lekhefu inika ingqiqo kwi-ductility ye-material. Ubude obuphezulu ngexesha lekhefu kuthetha ukuba i-geogrid inokolula ngakumbi ngaphambi kokungaphumeleli, okuluncedo kwizicelo apho kulindeleke intshukumo yomhlaba.
Izicelo kunye neeNzuzo
Amandla ei-uniaxial geogridsizenza zilungele uluhlu olubanzi lwezicelo. Ekwakhiweni kweendlela, zihlala zisetyenziselwa ukuqinisa i-subgrade layer, ukuphucula ukuhanjiswa komthwalo kunye nokunciphisa umngcipheko wokungaphumeleli kwe-pavement. Ekugcineni izicelo zodonga, i-uniaxial geogrids inceda ukuzinzisa umhlaba kunye nokuthintela ukunyakaza kwecala, ukuqinisekisa ukunyaniseka kwesakhiwo.
Enye yeenzuzo eziphambili zokusebenzisaPP uniaxial geogridkukukwazi ukuphucula ukusebenza ngokupheleleyo kwesakhiwo somhlaba. Ngokubonelela ngokuqina okongeziweyo, ezi geogrids zinokunciphisa kakhulu ukuhlaliswa kunye nokuguqulwa, ukwenza iziseko zophuhliso zihlale ixesha elide kwaye zithembeke ngakumbi. Ukongeza, ubume bazo obukhaphukhaphu bubenza kube lula ukuphatha nokufaka, ukunciphisa iindleko zabasebenzi kunye nexesha lokwakha.
ukuququmbela
Isishwankathelo, amandla e-uniaxial geogrids, ngakumbi i-polypropylene uniaxial geogrids, yinto ephambili ekusebenzeni kwazo njengezinto zokuqinisa kwizicelo zobunjineli boluntu. Ngenxa yokuba amandla okuqina ahluka ngokubanzi, iinjineli kufuneka zikhethe i-geogrid efanelekileyo ngokusekwe kwiimfuno ezithile zeprojekthi. Ngokuqonda iimpawu zamandla kunye neenzuzo ze-uniaxial geogrids, iingcali zinokwenza izigqibo ezinolwazi eziza kuphucula ukuqina kunye nokusebenza kwezakhiwo zabo. Njengoko imfuno yolondolozo, ulwakhiwo olusebenzayo luqhubeka nokukhula, indima ye-uniaxial geogrids kubunjineli bale mihla ngokungathandabuzekiyo iya kubaluleka ngakumbi.
