Isiphetho:Ngempela, ngokuya ngokwanda kwesidingo se-aggregate ye-sand ne-gravel, izinga ze-layini ezintsha zokukhiqiza i-sand ne-gravel zihlala zingaphezu kwezigidi ezingu-1.
Namanje, ngenxa yokwanda kwesidingo se-sand ne-gravel aggregates, umqondo wemigwaqo emisha yokukhiqiza i-sand ne-gravel uqiniswa ngaphezu kwetoni eyimiliyoni eyodwa ngonyaka, futhi ezinye zifinyelela izigidi eziyishumi ngonyaka. Ukuze umsebenzi wonke ufinyelele umphumela wokukhiqiza ohlanganisiwe, kufanele sicabangele izinto ezilandelayo ekuqaleni kokwakhiwa komsebenzi omusha:
Izinga lokusebenza kweprodukthi kufanele lihlangabezane nenqubomgomo.
Izinga lokusebenza kwekhwalithi yemveliso lingabhekwa ngokuyinhloko kula makhono amabili alandelayo:
Ikhwalithi ephezulu ye-aggregate egcwalisekile
Ikhwalithi yemveliso kumele ingagcini nje ngokugcwalisa izindinganiso zezwe, kodwa futhi kufanele ifinyelele izidingo zemarike.
I-aggregate ephezulu (i-aggregate enkulu ne-aggregate encane, i-aggregate encane yi-sand), okokuqala, umkhawulo wemifanekiso kufanele ubehlelekile; okwesibili, ukwahlukaniswa kufanele kube ngokuhlakanipha. Okukhulu kakhulu nge-sand eyenziwe ngemishini, imikhiqizo ye-sand eyenziwe ngemishini ephezulu kumele ingagcini nje ngokugcwalisa izidingo ze-sand ye-concrete yemarike, kodwa futhi kufanele kugcwalise izidingo zezindinganiso eziphakeme ze-ready-mixed.
Uqukethwe lwemhlabathi lusezingeni elifanele
Isimenye esiphezulu sokhwalithi sinezidingo eziphezulu kakhulu ngokuqukethwe kwemhlabathi. Elinye lamazimo okusebenza kahle kwelitha lama-sandu nama-gravel ukubeka iphroduthi ye-aggregate yolitha ukuba ihlangabezane nezidingo zokuqukethwe kwemhlabathi. E-China, kunesithwathwa esiningi emazweni aseNingizimu, futhi kunomkhawulo wamanzi emazweni aseNtshonalanga. Ezinye izindawo zokuchithwa zinezithambiso ezincane zemhlabathi, ezinye zinezithambiso eziningi zemhlabathi, futhi ezinye zinezithambiso ezengeziwe zemhlabathi, njalo njalo. Kumele kusetshenziswe izindlela ezahlukene ezimiqondweni ezahlukene; ngaphandle kwalokho kuzoholela ekuhlulekeni kweproyekthi.
Izinga lobukhulu bemgodla wemini liyichaza eminingi imiphumela yokuhlakanipha kwezinto ezifana ne-sand ne-stone, ezingashintshwe ngokushintsha umkhondo wemisebenzi yelinye i-production line, njengoba kunjalo ne-strength index, kanye nenani lokuqeqeshwa okufana nomkhonto, okuhlobene kakhulu nobukhulu bemgodla wemini, nenani lezinto ezisebenzayo ezifana nokuxuba, ubukhulu bemhlophe, njll.
Ngemuva kokuthuthukiswa kwalolu lwimi, kuzokwenzeka ukwakhiwa kwezinto ezinhle zokuhlakanipha kwelinye i-production line ngendlela ebonakalayo kanye ngokwengqondo, ukuze kutholakale umkhondo wokuqeqeshwa okusebenzayo.
2. Izinyathelo ezithile zokwakhiwa kwe-layini yokukhiqiza
Ikhono lokusebenza elihle
Isidingo esiyinhloko sokuba ne-layini yokukhiqiza ama-sandu nama-gravel ngokumelela kukuba nenqubo yokusebenza elungile. Inqubo elungile ibonakala ekulula kwesinqumo, kanye nokuba izixazululo zilungele ukusetshenziswa nokugcinwa kalula.
Ikhono lokusebenza elihle libonakala nakwibamba eliphansi lezixazululo ezisetshenziswayo kanye nokujwayelekile kwemodeli. Ukunciphisa inani lezixazululo kuholela ekutheni kube khona amaphoyinti amancane wokwehluleka, futhi lokhu kuzoholela ekutheni kube khona imali encane ezoqeshwa ekwakhiweni kwezibase.
Ukusebenza ngokuzenzekelayo nokuqonda
Inketho yesibili ebalulekile ekwakhiweni kweliyaqeqeshwa yikuthuthukisa izinga lokusebenza ngokuzenzekelayo, uqonde ukuqonda, ukunciphisa inani labaqeqeshwa, ukukhuluphisa izinga lokusebenza kwesixazululo, nokukhuluphisa isikhathi sokuqhubeka okungaphuthuki.
Ukuhlangabezana nezidingo zokukhuseleka kwesimo sezulu
Inketho yesithathu ebalulekile ekwakhiweni kweliyaqeqeshwa ukuba lihlangabezane nezidingo zokukhuseleka kwesimo sezulu futhi lihlangabezane nezindinganiso zokwakhiwa kweqembu elimhlophe, ngaphandle kwalokho ngeke liqhubeke.
Ngakho-ke, kuyaphakanyiswa ukukhetha iyunivesithi yokuhlolisisa enezipiliyoni eziningi ukuze yenze isimiso esiphelele nezindlela zokwakha zomsebenzi, noma kunganikwa kuyunivesithi yokuhlolisisa ukuze iqhubeke nokwenza umsebenzi ngokugcwele.
3. Ukukhetha imishini
Ukukhetha okufanele kwezinto ezisetshenziswayo kuyinto eyinhloko ekuqondeni impumelelo yelinye iqhinga lokuvelisa. Ukukhetha izinto ezisetshenziswayo elisebenzayo lokuvelisa i-sand ne-gravel kuyahlukaniswa ngokukhulu kokuhlobisa kokudla okuqala (njengokusimama kokudla okuqala, izinga lokuqondile, inani lomhlabathi, njll.).
Ngokuvamile, ilayini yemisebenzi ngayinye eyenzelwe futhi ikhethwe yiyunithi yokuhlolwa neyengqondo eyemvelo, ayisoze yaba nengxaki yokukhetha izinto ezihlobene. Nokho, njengoba abaningi abafundi be-layini yemisebenzi bengafuni izikhungo zokuhlolwa zokuhlolwa, bese bekopisha ngqo ukukhethwa kwezinto ezihlobene kwezinye izinkampani ukuze zikhiqize, kwakhiwa izinkinga ezinkulu zokukhetha izinto ezihlobene ngokungemthetho ngemuva kokusebenza.
Le ngxaki ngokuvamile iyingozi ukuyilungisa ngokuguqula inqubo, futhi umenzi kufanele asuse izinto ezihlobene ukuze kuqinisekiswe ukusebenza okuqinile nokusebenza kahle kwesikhathi eside.
Izindaba okufanele zicatshangelwe ekwakheni amayini okwesekwa
(1) Ukukhetha amayini kubalulekile kakhulu, futhi amayini akufanele akhethwe ngokuhambisana nezinhlobo zemikhiqizo ezihlongozwayo.
Kukhethwa kwezimayini, kungcono ukuba akukho ukuchithwa, indawo enhle kanye nezimo zomhlaba ezinhle, nokuthola indawo yemayini engabizi kakhulu yokumba. Ngokuqinisekile, uma izinsalela zegolide ezikhishwe emayini noma izinsalela zokuhlambulula ezingasetshenziswa, leli thuba kufanele linikezwe inani lokuqala.
(2) Kuyintokozo enkulu ukwakha indawo yemayini enengqondo futhi ehlelekile kusukela ekungabheki ngokuphelele ukwakheka kwemayini.
(3) Ukwakhiwa kwesitoreji lokukhiqiza isihlahla nensimbi kufanele kubhekwe njengomsebenzi oluhlelo oluhleliwe, futhi umsebenzi wemini kufanele ube ingxenye ebalulekile yaleli hlelo.
