Isiphetho:Ukusetshenziswa kabusha kwezinto ezilondoloziwe ezithathwe ezakhiweni nezibhujiswe (C&D) kubhekisela ekukhiqizweni nasekuqaleni kwempahla elisebenzisekayo kakhulu kusehlukanisweni lwempahla ehlukaniswe eziyisisekelo ezimisiweyo, okuqondile njengokushintshiselwa kokushintshiselana ngokweqile ngokukhishwa kwesakhiwo okushiwo emagcekeni.
Ukukhishwa kabusha kwezinto ezivela emakhaya nezindlu (C&D) kubhekisela ekuqoqweni nasekuqaliseni kabusha kwezinto ezisetshenziswa kabusha ezivela ezimbonini ezihlukaniselwe ezingeke zilahlelwe endaweni yokugcina impahla engasetshenziswa. Ngomklamo oqoqela izinto ezixhunyiwe, ukusetshenziswa kwazo kanye nokusetshenziswa kabusha, ukukhishwa kabusha kwe-C&D kuqinisa ukuthuthukiswa okusekelwe emhlabeni kanye nokulondolozwa kwesimo sezulu. Kuvumela izinto ezitholiwe ukuba zisetshenziswe kabusha, okuthuthukisa ukuphulukisa okuthuthukiswa kwezinto ezintsha zemvelo nokukhishwa kwezindawo zokugcina impahla engasetshenziswa.
Ukukhishwa kabusha kwe-C&D kunikeza isisombululo esisebenzayo sokuphathwa kwempahla yesakhiwo ngokuvumela izinto ezisebenzayo njengezinto eziphekwayo, imithi, izihlangu namaminerali ukuba zibuyele ekusetshenzisweni kabusha kwimboni.
Izinhlobo Zemathiriyeli yeC&D
Izinto zezokwakhiwa kanye nokubhujiswa (C&D) zihlotshanisa izingxenye ezahlukene zezinto ezingasebenzi ezisindiselwe ezisemisebenzini yokwakha imisebenzi yezokuhlela nokuqeqeshwa kwezakhiwo. Izinto ze-C&D ngokuvamile zinezinto ezinkulu, ezinzima ezifana nalezi:
- Amaqephu e-concret ephuka phansi
- Amaqhekeza e-asphalt pavement
- Uthuli lwemihlaba kanye namaggesi
- Amaqhekeza e-fired clay
- Izinto ze-metal ezahlukahlukene njenge-copper, aluminum kanye ne-steel
- Isandla kanye ne-granite
- Amakhukhuma e-timber
- Amaqhekeza e-plasterboard
Izinto eziningi ze-C&D zivikela ukubuyiselwa kwezinto kunokuxoshwa. Ngokwesibonelo, i-concrete ephutshiwe ingaphinde ibuyele njengesisetshenziswa esisha sezinto ezihlanganiswayo.
Izibonelelo Zokushintshiselana Kwempahla Ye-C&D
Ukushintshiselana impahla evela ezakhiweni nasekuqothweni kwempahla, kuyisixazululo esinezisusa esiqinisekisiwe sokuthuthukisa izinto zokwakha ezidingekayo ngesikhathi esifanayo kuqediwe ukushaya inhlawulo. Ukuthuthukisa impahla ye-C&D ngenqubo yokuvuselela imithombo kusizeleka ekwakhiweni ngezindlela eziningi:
Kubuyiselwe Impahla Yokwenza Imikhiqizo Emitsha
Impahla ye-C&D ihlanganisa impahla ehlukahlukene enomthamo olukhulu lomnotho njenge-aggregate, i-asphalt, imicu nemithi engasetshenziswa ngqo noma isetshenziswe ukuze kwenziwe izinto ezintsha. Ukushintshiselana kulezi mpahla kuvimbela ukwalahleka kwalezi mpahla. Amaqephu okusakazwa okunomkhiqizo okhulu we-konkrithi angatshiselwa kube sand.
Yonciphisa izindleko zokuhambisa nezimo eziyingozi
Ngenxa yokulungiselela isiqeshana eseduze nemizila yokususa, izidingo zokuhambisa ziyancipha. Izinto ezinzima kakhulu, ezinkulu ziyabuyiselwa zibe izinto ezincane, ezilinganayo ezinamathisela okusebenza okulula futhi okuphansi kakhulu ngenxa yokunciphisa imizamo yokulanda/ukukhishwa. Ukulungiselela kwangaphambili kubalulekile futhi kukhulisa ukwahlukaniswa kwezinto ezahlukene ukuze kube nezindlela ezikhiqiza ngokusebenza kahle. Lokhu kunciphisa kakhulu izindleko zokuhambisa ngesikhathi kwancipha ukukhishwa kanye nokungasebenzi kahle kwezindlela ezivela emisebenzini emikhulu yokuthutha.
Kusekela i-Circular Economy
Ngezinqubo zokushintshwa kabusha zokonga, izinto ze-C&D zingathola indawo ezinhlotsheni zokusebenza ezinkulu kunokuba zilashwe ngemva kokusetshenziswa okukodwa. Izinto ezisetshenziswa kabusha zifeza izikhathi ezide eziphindaphindiweyo eziqinisekisa ukusetshenziswa okuhle kwezinto ezakhiwayo ngokuvumelana nemibono yomnotho oqeqeshwe kabusha. Ngenxa yokwehla kwamacala ezihluthi ze-C&D ezidinga ukubonisa, kunesidingo esincane sezinto ezintsha ezivela emvelweni ukugcina ukukhiqizwa.
Yonqanda Umkhondo we-Carbon
Lapho iconcreti, i-asphalt, i-wood kanye nezinye izinto eziphindaphindiwe zingezinto eziqeqeshwe kabusha njengezinto ezihlukaniswe nezinto ezintsha, kakhulu ukukhishwa kwe-carbon kunokukhiqiza izindleko zokuguqulwa ngamandla.
Izimbobo zekhonkrithi eziphindwe zisetshenziswa ezitholwe emgodini wezakhiwo nezinto eziqediwe
Izingxube zekhenkcezwe eziphinde zisetshenziswe ezitholwe esichitshiselweni sokwakha nokuqothula (C&D) zihlobene nezinto ezinemifanekiso ezisezansi kwama-40mm ezitholakale eziqithini zekhenkcezwe ezitholakala ekubhujisweni kwezakhiwo, ekulungisweni kwezindlela, ekukhiqizweni kwekhonkcezwe, ekwakheni kwezinhlelo zezokuhlaziya nezinye imisebenzi.
Izingxube zekhenkcezwe eziphinde zisetshenziswe zihlukaniswe zibe izinhlobo ezimbili ngokwekhulukazi kwemifanekiso:
Izingxube zekhenkcezwe eziphindwe zisetshenziswe ezinkulu zinemifanekiso enkulu kunoba lingana noma ngaphezu kwama-5mm kodwa ingaphansi kwama-40mm. Zingathatha indawo yingxube yezinto ezazisetshenziswa ngokwemvelo emisebenzini yokukhiqiza ikhenkcezwe ngenxa yengxenye. Ikhonkcezwe eyenziwe ngokuthatha indawo yengxenye yemifanekiso inomzimba onjengomzimba wezokuhlaziya ezazisetshenziswa ngokwemvelo.
Amaqophela okulungiswe kabusha amancane anezingcezu ezinkulu kunama-0.5mm kodwa amancane kunama-5mm. Angasetshenziswa ngokungenelela amaqophela amancane emvelo eziqhingini eziningi zokuthwala umthwalo nasezingekho ngokuthwala umthwalo. Amaqophela okulungiswe kabusha amancane angasetshenziswa futhi esikhundleni sasetshenziswa lesihlabathi ezigodini ezingekho ngokuthwala umthwalo noma sisetshenziswe ukwenza i-mortar yesihlabathi okulungiswe kabusha.
Ngenkathi izakhi ezintshintshisiwe zihluke kancane ezakheni zemvelo ezimfushane, izinto ezintshintshisiwe ezixoshwe yi-vibration ngezinto ezincane kakhulu nezinhlayiya eziphakeme zifana kakhulu nezakhi zemvelo ezimfushane emibonini. Ukusetshenziswa okuhle kungadala izakhi ezintshintshisiwe ezihlangabezana nemikhawulo efanele. Ikonikri yebetoni eyenziwe ngezakhi ezintshintshisiwe ezilawulwe kahle inganciphisa izindleko zebetoni elikhulu elikhulu, yiguqule izinto zokwakha, yanciphisa ukukhishwa kwezinto zeminerali, futhi yiguqule isisulu sokwakha isizakhiwo sibe yinto ehlanzekile, yokuvikela imvelo.
Ukusetshenziswa kwezinto ezihlanganisiwe zekholi ye-konkrithi ephinde isetshenziswe:
- I-konkrithi ephinde isetshenziswe, imorteri, amabhodi, amathende namabhodi okulungiselela ubunjiniyela bezakhiwo
- I-konkrithi ephindaphindekayo, amathende, izinto ezihlanganisiwe ezingavamile, izinsimbi ezihlanganisiwe nezinto zokugcwalisa ezimhlophe zokuhlela izifundazwe nezokuthutha
- Izinto ezihlanganisiwe zokwakhiwa kwesifundazwe esinamanzi njengezinto eziluhlaza
- Izimpahla ze-konkrithi ezixhunywe izinhlaka ezingezansi njll.
