Kwadalwa ngo 03.12
Emkhakheni wobunjiniyela bomphakathi nokwakhiwa, ukusetshenziswa kwama-geosynthetic kudume kakhulu. Phakathi kwezinto lezi, i-geogrid ne-geotextile yizinto ezimbili ezibalulekile ezisebenza izinjongo ezihlukile. Ukuqonda umehluko phakathi kwazo kubalulekile empumelelweni yamaphrojekthi ahlukahlukene.
Ukukhetha phakathi kwe-geogrid ne-geotextile kuncike ezidingweni ezithile zephrojekthi, okubandakanya uhlobo inhlabathi, umthwalo okufanele uwuthwale, kanye nezimo zemvelo. Lesi sihloko sihlose ukuhlinzeka ngokuqhathanisa okuphelele kwezinto lezi, sihlola izindlela zazo zokusebenzisa futhi siqondise abafundi ukuthi bangakhetha kanjani ezifanele kakhulu ngezidingo zabo.
Amaphuzu Abalulekile
- I-Geogrid ne-geotextile zombili ziyizinto ze-geosynthetics ezisetshenziswa emaphrojekthini ezobunjiniyela bomphakathi kanye nokwakhiwa.
- Umehluko oyinhloko uphathelene nesakhiwo sawo kanye nokusetshenziswa kwawo: i-geogrid isetshenziselwa ukuqinisa, kanti i-geotextile ivame ukusetshenziselwa ukuhlunga nokuhlukanisa.
- Ukukhetha impahla efanele kuncike ezidingweni ezithile zephrojekthi njengohlobo lomhlaba nezidingo zokuthwala umthwalo.
- Ukuqonda izindlela zokusebenzisa impahla ngayinye kubaluleke kakhulu empumelelweni yamaphrojekthi okwakha.

Yebo, i-geogrids ne-geotextiles zingasetshenziswa ndawonye ukuze kuzuzwe izinzuzo ezihlangene, kuthuthukiswe ukusebenza jikelele nokuzinza kwezinhlelo zokwakha.
Ngiyikhetha kanjani phakathi kwe-geogrid ne-geotextile kuphrojekthi yami?
Ukukhetha kuncike ezidingweni zephrojekthi, izimo zenhlabathi, ukuhlolwa kwendawo, kanye nezinto ezibhekwa ngesabelomali. Ukuhlola lezi zici kuzosiza ukunquma ukuthi i-geogrid, i-geotextile, noma inhlanganisela yazo zombili iyona efanele kakhulu.
Yiziphi izinhlelo ezivamile ze-geogrids?
Ama-geogrids avame ukusetshenziswa ekwakhiweni kwemigwaqo nemikhawulo, ezindongeni zokubamba, emithambekeni emikhulu, nasekuqinisweni kwezisekelo, ahlinzeka ngokuzinza nokuqiniswa kwenhlabathi.
Yiziphi izinhlelo eziyinhloko ze-geotextiles?
Ama-geotextiles asetshenziselwa ukulawula ukudilika, ukuhlunga, ukudonsa amanzi, nokuhlukanisa, adlala indima ebalulekile ekugcineni ubuqotho bephrojekthi yokwakha nasekuvikeleni ukonakala kwemvelo.
Ingabe kukhona izindinganiso ezithile zobuchwepheshe ze-geogrids ne-geotextiles?
Yebo, ama-geogrids nama-geotextiles ahluleka ezindinganisweni ezahlukene zobuchwepheshe, kuhlanganise nezindinganiso ze-ASTM, eziqinisekisa ikhwalithi yazo nokusebenza kwazo ngokuhlolwa okuqinile kanye nezinyathelo zokulawula ikhwalithi.
Yini izinzuzo zokusebenzisa ama-geosynthetics afana nama-geogrids nama-geotextiles?
Ama-geosynthetics anikeza izinzuzo eziningi, kuhlanganise nokuthuthukiswa kokuzinza, ukuthuthukiswa kokuphila, kanye nezindleko eziphumelelayo, okwenza kube izinto ezibalulekile ekwakhiweni kwanamuhla nasezinhlelweni zobunjiniyela bezakhamuzi.
Ama-geogrids nama-geotextiles anikela kanjani ekugcineni kwemvelo?
Ngokuvimbela ukuhuzuka, ukuthuthukisa ukugeleza, nokuzinza komhlabathi, ama-geogrids nama-geotextiles anikela ekugcineni kwemvelo, kunciphisa umthelela wemvelo wezinhlelo zokwakha.
