I-Geosynthetic Reinforcement

Ukuqiniswa kwe-geosynthetic kuyindlela ebalulekile yokuzinza komhlaba esetshenziswa ukuze kuthuthukiswe amandla okuphatha nokuzinza kwezendlalelo zomhlaba kumaphrojekthi wezimpande ezijulile nasemisebenzini yomhlaba. Le ndlela ihilela ukusatshalaliswa kwempahla ebhalwe phansi njengama-geogrids, ama-geotextiles, ama-geocells, kanye nama-geomembranes ngaphakathi kwezakhi zesihlabathi ukuze kuthuthukiswe ukusatshalaliswa komthwalo, kuncishiswe ukuwa, futhi kuvinjwe ukuhamba komhlaba ngokujula. Ukusetshenziswa kwe-geosynthetics kuphendula ezintweni ezithile eziphukile zomhlaba wemvelo, ikakhulukazi ezindaweni ezinomhlaba ophansi, ama-clays ansimbi, noma izinto zebhande ezilula ezingakwazi ukujabulisa amandla aphakeme adingekayo. Ngokuqinisa umxube womhlaba, lezi zimpahla zakha uhlelo lwezinto ezihlanganisiwe olukhulisa kakhulu amandla okuphatha kanye nekhwalithi yesakhiwo somhlaba, okwenza kube nezindleko eziphansi ukuba kwakhiwe ezindaweni ezazingafaneleki kahle noma ezinzima. Ukusebenzisana kokuqiniswa kwe-geosynthetic kuhilela izindlela eziningi ezikhethekile ezakhelwe izimo zomhlaba ezithile zephrojekthi kanye nezidingo zesakhiwo. Ama-geotextiles asebenza njengemizila yokuhlukanisa nokuqinisekiswa, avimbela ukuhamba komhlaba okuncane ngenkathi kugcinwa ukuqina kwamanzi. Ama-geogrids, anombono wendawo ovulekile, anikeza ukuqina komhlaba okuqondile ngokuvimbela ukuhamba komhlaba ngokujula nokusabalalisa imithwalo egxilile ezindawana ezibanzi zomhlaba. Ama-geocells asebenza njengohlelo oluncane lwezinto ezintathu ezivimbela ukuhlanganiswa kwezinto kanye nokuhamba komhlaba, okuhlanganisa kahle ekwakhiweni kwe-emankment nasekuphakanyeni izimpande ezinzima. Ukukhethwa kwefomu lempahla, usayizi we-aperture, amandla okudonsa, kanye nobude bokufaka kuncike ekuhlaziyweni kwemekhanika yomhlaba, izimo zomthwalo ezilindelekile, kanye nezimo zemvelo. Imishini evamile esetshenziswa ifaka ama-vibro-compactors kanye nama-plate compactors ukuze kuqinisekiswe ukufakwa kahle nokuhlanganiswa kwemithwalo phezu kwezendlalelo ze-geosynthetic, kanye ne-cranes ezihambayo kanye nezihambisi zokufaka izinto ezindaweni zomhlaba. Ukuqiniswa kwe-geosynthetic kufakwa ezimeni ezahlukene ze-geotechnical lapho ukuthuthukiswa komhlaba okujwayelekile kutholakala kungenanele noma kuphansi kwezindleko. Kumaphrojekthi wezimpande ezijulile, lezi zimpahla zisetshenziselwa ngaphansi kwezindonga ze-pile namafutha asabalalayo ukuze kuthuthukiswe ukusatshalaliswa komthwalo futhi kuncishiswe ukuwa okuhlukeneyo. Ekukhiqizeni i-emankment phezu kwemithombo ethambile, ama-geogrids anikeza ukusiza okuqhakazile kanye nezinga, kunciphisa ingozi yokwehlisa ukuhlala nokwenziwa kwemisebenzi ye-emankment. Ukuqina komgwaqo nokuvikela imizila ye-railway kudlula kakhulu ezindleleni ezihambelanayo ze-geotextile-geogrid ezihlukanisa izinto zomgwaqo, ziqhubekisela phambili imithwalo ye-wheels, futhi zwandise impilo yokusebenza ye-pavement. Ukuqiniswa kwezindlebe kanye nokuvikela emiphakathini kuvuna ama-geocells kanye nama-geotextiles ukuqinisa iziQhingi eziphakeme futhi kuvinjeze ukuhamba kombhobho. Ngaphezu kwalokho, izixazululo ze-geosynthetic ziphendula ukuthuthukiswa komhlaba ezindaweni ezibhekelela ukudilizwa, ezinamandla aphansi, kanye nezimo zomhlaba eziyinkinga lapho izindlela ezijwayelekile zezimfundamakhwela zibhekana nezinkinga, kugcina kwehlisiwe izindleko zephrojekthi nomthelela wemvelo ngenkathi kuthuthukiswa ukusebenza kwesakhiwo eside nokuphepha.
