Ama-Nails e-GRP/FRP

Iziqeshana ze-GRP ne-FRP zimelela izixazululo ezithuthukile nezisetshenziswa ekuzinziseni kwamathafa nasezinhlelweni zokubopha umhlabathi emisebenzini ye-geotechnical engineering. Lezi zinto zokwakha ezihlanganisiwe, ezenziwe ngezinto ezinamathambo esikhumba noma ezakhiwe ngofiber, zinikeza ukusebenza okuphezulu ezinhlelweni zokubopha umhlabathi eziklanyelwe ukuvimbela ukuwohloka kwamathafa nokuthuthukisa ukuzinza komhlaba. Ngokungafani nezinsika zensimbi ezidla ukugqwala, iziqukathi ze-GRP/FRP zifika ngokuphelele ekubeni ziqine njalo isikhathi eside, ikakhulukazi ezindaweni ezinzima zomhlabathi, ezindaweni zasolwandle, noma ezindaweni ezinezimo zamanzi aphakeme. Ukuze zingagqwali, lezi zinto zenza ziphumelela kumaphrojekthi lapho ukumelana nokugqwala kubalulekile futhi izindleko zokugcina isikhathi eside kufanele zinciphise. Iziqeshana ze-GRP ne-FRP zisetshenziswa kakhulu kumaphrojekthi okuvuselela amathafa ezimo ze-geological ehluke-hlukeneyo, kuhlanganisa umhlaba wamakhayithi, amathafa anempundu, kanye nezinhlobo zejolile zomhlaba lapho izindlela zokwakha ezijwayelekile zingase zibe nezinkinga zokuguguleka. Ukufakwa kweziqeshana ze-GRP ne-FRP kulandela izindlela ezisungulwe zokubopha umhlabathi ezihlanganisa ukukhiya izimbobo ezikwehlile kumathafa, ukufaka iziqeshana ezihlanganisiwe, nokuhlobisa kahle ngaphakathi komhlaba. Imishini ethile yokukhukhumala ekwazi ukuhlinzeka ngamabhoshongo angakukholwa iyadingeka ukuze ifakwe kahle, lapho ubude beziqeshana obujwayelekile bujwayele ukuba phakathi kuka-5 no-15 amamitha kuye ngokwakhiwa kwamathafa kanye nezidingo zokuzinza. Inqubo yokuhlobisa, esebenzisa izinhlelo zokuhlobisa ezisekelwe kumatshe noma ezisekelwe kumaresini, iqinisekisa ukuhlanganiswa okuphelele phakathi kweziqeshana nomhlaba ozungezile, ukudala umthamo ophathekayo oqinile ophikisa ukwehla kwe-shear. Ukulandelanisa kokufakwa kuqala phezulu kuze kube phansi kumathafa, kuvame ukuhlanganiswa nezici ezithile ezifana ne-shotcrete noma amaphaneli aqinile omhlabathi ukuze kuthuthukiswe ukuzinza kwendawo futhi kugcinwe umhlaba ophephile. Ukuqinisekiswa kokuthile ngesikhathi sokufakwa kubandakanya ukuqinisekiswa kwemigqa yamabhoshongo, ukuqinisekiswa kokuphothulwa kokuhlobisa ngokuthatha izilinganiso zendlela yokuhlobisa, kanye nezivivinyo ze-load testing ukuze kuqinisekiswe ukuthi kukhona amandla aphezulu okuhamba. Iziqeshana ze-GRP ne-FRP ziwusizo kakhulu kumaphrojekthi abhekene nezimo zemvelo, ukuvuselela umhlaba ophukile, kanye nezindawo ezidinga ukuqinisa okungesona insimbi ngenxa yokuxhumana nezinsizakalo noma izimo ze-electromagnetic. Iziqeshana ezilula zenziwa kube lula ukuhamba nokufaka kumazinga izinsimbi, kwehlisa izidingo zemishini nezikhathi zamaphrojekthi. Lezi zinto zisebenza kahle kakhulu ezimweni zomhlaba ophezu komswakama, umhlaba wokwakha, nezindawo ezinomsebenzi ophusile, okwenza kube izixazululo ezikhethwayo ezindaweni zokwakha umgoqo wezitimela, iziqeshana zomgwaqo, nezindawo zokugcina amathafa edolobheni lapho ukuvinjelwa kwendawo kanye nokuvikelwa kwemvelo kubaluleke kakhulu. Ukuhlaziywa kwezindleko-nezindawo kunezizathu ezenzakalayo ezikhetha izixazululo ze-GRP/FRP ezindleleni ezindala lapho ukunciphisa ukugcinwa, ukuxazulula izinkinga ezidinga ukuguga, kanye nezimpilo zezinqubo zesistimu ezinde zenza izinzuzo zomnotho ezinkulu phakathi nesikhathi sokusebenza kwesakhiwo.
