Intshayelelo yeMveliso
Ukuma kwesixhobo:
Itekhnoloji ye-Tunneling eKhuselekileyo kwi-Heterogeneous Ground
Imeko yokwakheka komhlaba:
Umhlaba othambileyo, ukumila okungafaniyo (isanti, igrabile, ukungeneka okuphezulu kunye noxinzelelo oluphezulu lwamanzi)
Uluhlu lwe-NPD umbhobho wokutyhutyha umatshini ulungele kakhulu iimeko zejoloji kunye noxinzelelo oluphezulu lwamanzi aphantsi komhlaba kunye ne-coefficient ephezulu yokungena komhlaba. I-slag ekhutshiweyo ikhutshwe kwi-tunnel ngendlela yodaka ngokusebenzisa ipompo yodaka, ngoko ineempawu zokusebenza okuphezulu kunye nokusebenza okucocekileyo kwendawo yokusebenza.
Ngokweendlela ezahlukeneyo zokulawula udaka kwindawo yokwembiwa, umatshini we-NPD wokutyhutyha umbhobho wechungechunge unokwahlulwa ube ziindidi ezimbini: uhlobo lolawulo oluthe ngqo kunye nohlobo lolawulo olungathanga ngqo (uhlobo lolawulo loxinzelelo lomoya).
a. Umatshini wokulawula ngokuthe ngqo umbhobho we-jacking unokulawula uxinzelelo olusebenzayo lwetanki lamanzi odaka ngokulungelelanisa isantya sempompo yodaka okanye ukulungelelanisa ukuvulwa kwe-valve yokulawula amanzi odaka. Le ndlela yokulawula ilula kwaye ifanelekile, kwaye izinga lokungaphumeleli liphantsi.
b. Umatshini wokulawula umbhobho we-jacking ngokungathanga ngqo ulungelelanisa uxinzelelo olusebenzayo lwetanki yamanzi enodaka ngokuguqula uxinzelelo lwetanki ye-cushion air. Le ndlela yokulawula inempendulo ebuthathaka kunye nokuchaneka kokulawula okuphezulu.
1. I-automatic control cushion air cushion inokubonelela ngenkxaso echanekileyo yobuso betonela, ukwenzela ukuba kuqinisekiswe ukhuseleko lokuqhuba itonela ukuya kwinqanaba elikhulu.
2. I-Tunneling inokuqhutywa kwakhona xa uxinzelelo lwamanzi lungaphezu kwe-15bar.
3. Sebenzisa udaka njengendlela ephambili yokulinganisa uxinzelelo lokubumba kwindawo yokwemba kwitonela, kwaye ukhuphe i-slag ngokusebenzisa inkqubo yokuhambisa udaka.
4. Umatshini we-NPD wokutyhutyha umbhobho ulungele ukwakhiwa kwetonela kunye noxinzelelo oluphezulu lwamanzi kunye neemfuno zokuhlaliswa komhlaba.
5. Ukuqhuba kakuhle kakhulu, ukhuselekile kwaye unokwethenjelwa, kunye neendlela ezimbini zokulinganisela zokulawula ngokuthe ngqo kunye nokulawulwa ngokungathanga ngqo.
6. Uluhlu lwe-NPD lwe-pipe jacking machine kunye noyilo oluphambili kunye noluthembekileyo lwe-cutter kunye nokujikeleza kodaka.
7. Umatshini we-NPD woluhlu lwe-pipe jacking wamkela i-bearing ethembekileyo ephambili, itywina eliphambili lokuqhuba kunye ne-drive reducer, kunye nobomi benkonzo ende kunye nokhuseleko oluphezulu.
8. Inkqubo yokulawula isoftware ephuhlisiwe, ukusebenza kwawo wonke umatshini kukhuselekile kwaye kunokwethenjelwa, kwaye ukusebenza kulungele.
9. Umhlaba osebenzayo obanzi osebenzayo, onjengomhlaba othambileyo, udongwe, isanti, umhlaba wegrabile, umhlaba oqinileyo, ukubuyisela umva, njl.
10. Isitofu samanzi esizimeleyo, inkqubo yokukhupha.
11. Esona santya sikhawulezayo siphantse sibe ngama-200mm ngomzuzu.
12. Ukwakhiwa kokuchaneka okuphezulu, ukuqondisa mhlawumbi phezulu, phantsi, ekhohlo nasekunene, kunye neyona angle yokulawula i-5.5 degrees.
13. Sebenzisa inkqubo yolawulo esembindini emhlabeni, ekhuselekileyo, eqondakalayo, kwaye eluncedo.
14. Uluhlu lwezisombululo ezenziwe ngokufanelekileyo zinokubonelelwa kwiimfuno ezahlukeneyo zeprojekthi.
