Indlela Yomshayeli Wasezulwini: Izimangaliso Ezilungileyo Zokusetshenziswa Kuzimali, Umcubhenkulu, Nezihlalo Ezintsha
Umphakathi wokwakha umndeni oyingcwele wasezulwini yindawo ebalulekile yokuthenga kumashini wezwire zezibhamu, ekunika indawo yokusebenza engqondweni ne-engqondweni. Izwire zegeotextile—ezakhiwa ngale mikhumbi kumathilithi njengepolyester futhi polypropylene (PP)—ziyizikrha ezibalulekile zezinto ze-geotextile ezisetshenziswa ukukhupha izindlela nezinhlophe, ukwahlukanisa ubuso bezimali emabhenjini eziningi, nokukhupha ukungafuni kwamanzi emaphrojekthi wamanzi (njengamabhodlensi namathekwane). Ngokuthuthuka kwebandla lokwakha (njengeminyaka yendawo, ukuthuthuka kwezinhlophe zomgudu) nokulungiselela kwebandla eliphelile, kunezidingo eziphakade kumashini wezwire ze-geotextile azakwakha i-zwire nge-tensile strength engeyi futhi ayithobele imvula. Abayakha amakhambi ane-machines anesitinga esifakiwe sokushintsha kudiameter wezwire ukuze akwazi ukufakela i-geotextile ngazo zonke izinhlobo (nezihlanganisiwe, nezingahlanganisi), baya kudinga kakhulu yizidingo zombalimbali zemaphrojekthi.
Indawo yokubuyisa kulesikhathi nezimali zokuphepha kwezamashishini yayisakazeka njengendawo ephuthelana ngokukhulu yomsebenzi wamashine emshanelweni we-geotextile, ihlophwe ngizinhilo zokuphila kusasishiyagalombili. Lezi ziphetho zihlela i-wire ye-geotextile ezifanelekileyo ngesitinga sokuphepha kwezamashishini njengekugcina komlaba nemifula emakhanda, ukubuyisa kulesikhathi kwemifula yezilwane, nokubuyisa izindiza. I-geotextiles ezibekwa kulezi wire zivikela umlaba ukungahleleki, kunceda ukuthutha kwemithi, futhi zihlambalaza izinkunzi emifuleni—okubalulekile ekufanisweni nezimiso zokuphepha kwezamashishini (umzekelo, ukulingana kwe-carbon, ukulawula kwebhubhu yemifula). Amashine e-geotextile wire angakwazi ukusebenzisa amapholima afakiwe (ukuthula kwezingo zokuphepha) noma ukwenza i-wire engahlali kwi-UV (ukunikeza ubude bebusuku bempilo yezinto emangqamuzeni) ayithandwa ngaphezu kwezinye ngucomophaka wezimali zokuphepha, ethola imithombo yokuqhubeka ekuthuthakeni kulezi ziphetho.
Izimo ezihlelekileyo zejinjiniya zibonakala kuthutha izimo eziphambili zokusetshenziswa kwamashini ebhola lwegeotextile, ekhulula imithombo yomthongo wazo. Kwiinxalenye ezikumlanjeni, le mishini ihlinza amabhola abhephayo geotextile ngokukhanda kwezimali ezingaphantsi kwezimali, futhi ayilungise ixesha elibi phantsi kwegolide. Kugeqhamekaziwe, le mishini ihlinza amabhola amakhulu angaphansi kwebhola elihleli ngezimali, futhi ayilungise ukuguquka kwegolide. Ngaphezu koko, kumzekelo wokugcina inkunkuma, le mibhola isetshenziselwa ukwenza i-geotextiles yokuhlengahlenga kwamanzi aphelene, ukuze kugcinwe ubunyange balesilimela nezimali ezincane. Njengoba lezo zimo zihlelekile ziyakhula, amashini ebhola geotextile anemiseko yokwakha (njengekukhuphuka, ukwakha okuphakeme) zizovezwa njengezixhobo ezibalulekile kubunesi obafuna ukufinyelela emathongweni afana ne-geotextile.
