Ukuphatha amalahle kwimizi-mveliso yombane kunye nemathiriyeli eninzi ehanjiswa kwimizi-mveliso yesamente, ingabekwa njani indlela yokuhambisa enqumla kumakhulu eemitha: intsimbi yokuhambisa intsimbi engaphezulu okanye igalari yokuhambisa engaphantsi komhlaba?
Amaqela amaninzi eprojekthi aqala athanda indlela engaphantsi komhlaba kuba igcina indawo icacile kwaye ibonakala ilula. Kodwa xa imisebenzi yoluntu, ukufikelela kulondolozo, kunye nokusetyenziswa komhlaba kuqwalaselwa kunye, isiphelo sihlala sitshintsha. Okukhona ubude bexesha kunye nokuntsonkotha komhlaba, kokukhona kucaca ngakumbi izibonelelo zesakhiwo sentsimbi yokuhambisa i-trestle.
Esi sikhokelo sibonelela ngesakhelo esisebenzayo sokukhetha indlela, kusetyenziswa izakhiwo zentsimbi ezinikezelweyo kwiinkqubo zokuphatha amalahle njengezalathiso zeprojekthi.
Iindleko eziNtathu ezifihlakeleyo zeGalari yoThutho engaphantsi komhlaba
Imisebenzi yoMhlaba kunye noLwakhiwo oluphantsi komhlaba
Igalari yokuthutha engaphantsi komhlaba ifuna ukugrunjwa, ukunqunyulwa, kunye nokuzaliswa ngasemva. Apho amanzi aphantsi komhlaba akhoyo, amanyathelo okucoca kunye nokuthintela amanzi nawo ayafuneka. Kwizityalo ezineemeko ezinzima zomhlaba, iishedyuli zomsebenzi woluntu kunye neendleko kunokuba nzima ukuzilawula. Ixesha lemvula linciphisa ngakumbi ifestile yokwakha ekhoyo.
ULondolozo kunye neMisebenzi
Xa isithuthi sebhanti sifakwe ngaphantsi komhlaba, izithuba zokungena zilinganiselwe, kwaye ukutshintshwa kwabantu abangasebenziyo kunye nokuhlolwa kwesiqhelo kufuna umsebenzi ongaphantsi komhlaba. Iindleko zokhuseleko ezibangelwayo kunye nokulahlekelwa kokusebenza kakuhle kokugcinwa kubomi benkonzo yenkqubo zihlala zijongelwa phantsi ngexesha lokukhetha.
Ukusetyenziswa okusiGxina kweSithuba soMphezulu
Indawo engaphezulu kwegalari engaphantsi komhlaba ayinakulayishwa ngokukhululekileyo, ilungiswe, okanye iphuhliswe. Ngokwesiqhelo, esi siqwenga somhlaba sizinikele ngokusisigxina kwinkqubo yokuhambisa, ukunciphisa ukuguquguquka kwekamva kuyilo lwesityalo.
Ingqiqo yesakhiwo se-Overhead Steel Conveyor Trestle
Kutheni iZakhiwo zeNtsimbi zifanele iindlela eziPhakamileyo zoThutho
Izakhiwo zentsimbi zidibanisa ubunzima obuphantsi kunye namandla aphezulu. I-overhead conveyor trestle ixhaswa kunyawo lomntu ngamnye, ukuthintela imfuno yomsele ogrunjwayo ngokuqhubekayo. Iitrasi zentsimbi kunye nezakhiwo ze-space-frame ziifom ezimbini eziqhelekileyo ezinokufikelela kwi-spans emide kunye neenkxaso ezimbalwa:
| Ifom yesakhiwo | Uluhlu lwexesha eliqhelekileyo | Iimpawu eziphambili |
| Intsimbi yentsimbi (iplanar okanye ispace truss) | Malunga. 30-100 m | Ukuqina okuphezulu; ilungele imithwalo enzima kunye neendlela ezide, eziqhubekayo |
| Isakhelo sesithuba / iqokobhe lelayisi | 100 m nangaphezulu | Ubuchule obugqwesileyo bokujikeleza; amalungu asemgangathweni |
Isithuba senkxaso kwiitrestles zokuhambisa intsimbi ngokuqhelekileyo yi-6-10 m. Amalungu ayilwe kusetyenziswa iimodyuli ezisemgangathweni, ezenziwe ngaphambili kwindawo yokusebenzela, emva koko zidityaniswe kunye kwaye ziphakanyiswe endaweni kwindawo.
IiShedyuli eziMfutshane NgokuLungisa iFactory Prefabrication
Amalungu entsimbi adityanisiwe kwaye agqunywe kwindawo yokusebenzela, eshiya ukuphakanyiswa kunye nokudibanisa njengeyona misebenzi iphambili kwisiza. Oku kunciphisa ukuba sesichengeni sokulibaziseka kwexesha lemvula elinxulunyaniswa nomsebenzi womhlaba, kwaye ufakelo lungagqitywa ngokukhawuleza kakhulu kunesisombululo somsebenzi ophantsi komhlaba. Isalathiso seprojekthi ye-ZM-Besta: ulwakhiwo lweqokobhe lelattice kwiyadi yamalahle ejikelezayo enobubanzi obuyi-90 m yagqitywa kwiinyanga ezi-3 zizonke.
uKhuseleko lokuRhakala kunye neendleko zoMjikelo woBomi
Iitrestles zentsimbi yokuhambisa ngaphezulu zinokukhuselwa ngeenkqubo zokugquma ezifakwe kwivenkile okanye igalvanizing eshushu. Kwiindawo ze-atmospheric ye-industrial, inkqubo yokwaleka ingaba nobomi benkonzo yokuyila iminyaka eyi-15-25, kunye nokugcinwa kokugcinwa okunye ngelo xesha. Nangona isakhiwo sekhonkrithi yegalari engaphantsi komhlaba ayigqwali, ukuwohloka kokuthintela amanzi kunye neendleko zokulungisa ukungena kwamanzi kusafuneka kuqwalaselwe.
Isakhelo sokuKhetha: Ungayikhetha nini i-Overhead Steel Conveyor Trestle
Phonononga iimeko zeprojekthi ngokuthelekisa le migaqo ilandelayo:
| Imeko yeprojekthi | Ukhetho olucetyiswayo | Isizathu |
| Iindlela zinqumla iindlela, oololiwe, imilambo, okanye iindawo zokubeka imibhobho esele ikho | Overhead steel conveyor trestle | Ngokuqhelekileyo eyona ndlela isebenzayo; isakhono sobubanzi sibalulekile |
| Indawo encinci yomhlaba; iindlela zolungiselelo kufuneka zihlale zikhona | Overhead steel conveyor trestle | Ugcina iindlela zokujikeleza ezikumgangatho osezantsi zikhona |
| Amanzi aphantsi komhlaba aphezulu, i-geology enzima, okanye ixesha elide lemvula | Overhead steel conveyor trestle | Iphepha kakhulu iindleko zokugrumba, ukususa amanzi, kunye nokususa emanzini |
| Iimfuno zokusingqongileyo zifuna ukuhanjiswa okuvalekileyo, nokulawulwa uthuli | I-Overhead trestle + igalari evaliweyo | Igalari yentsimbi evaliweyo yefreyimu yesithuba idibanisa ixesha elide lokuwela kunye nesithintelo |
| Umhlaba othe tyaba, akukho zinqumlo, kwaye akukho setyenziso lucetyiweyo lomphezulu | Thelekisa negalari engaphantsi komhlaba | Ukhetho oluphantsi komhlaba lunokuba nokhuphiswano kwiindleko zomsebenzi woluntu kule meko |
Umgaqo omnye osisikhokelo: Okukhona ukunqumla indlela isiba nde kwaye ubude bayo bubude, kokukhona ukomelela kwexabiso lilonke inzuzo yentsimbi yokuhambisa ithande ukuba njalo. Ixabiso elithe ngqo ngemitha yegalari engaphantsi komhlaba linokuba ngaphantsi, kodwa yakuba imisebenzi yoluntu, ishedyuli, ukugcinwa, kunye nokusetyenziswa komhlaba kubandakanyiwe, isisombululo esiphezulu sihlala sinokhuphiswano ngakumbi kwiindlela ezihamba ixesha elide.
IiReferensi ezivela kwiiProjekthi ezinikezelweyo
I-long-span conveyor trestles kunye nezakhiwo zentsimbi kwiinkqubo zokuphatha amalahle yilayini yemveliso ekhethekileyo ye-Xuzhou ZM-Besta, egquma ikhonkco elipheleleyo ukusuka kuyilo kunye nokwenziwa ukubonelela kunye nofakelo. Iiprojekthi ezizisiweyo ziquka:
