Isingeniso Somkhiqizo
Ukuma kwedivayisi:
I-Safe Tunnel Technology in Heterogeneous Ground
Isimo sokwakheka komhlaba:
Umhlabathi othambile, ukwakheka okuhlukahlukene (isihlabathi, amatshe, ukungena kwamanzi okuphezulu kanye nomfutho ophakeme wamanzi)
Umshini wokuthungatha amapayipi ochungechunge lwe-NPD ulungele kakhulu izimo ze-geological ezinomfutho ophakeme wamanzi angaphansi komhlaba kanye ne-coefficient ephezulu yokungena kwenhlabathi. I-slag embiwe ikhishwa emhubheni ngendlela yodaka ngokusebenzisa ipompo yodaka, ngakho inezici zokusebenza kahle okuphezulu kanye nendawo yokusebenza ehlanzekile.
Ngokwezindlela ezihlukene zokulawula udaka endaweni yokumba, umshini wokuthungatha amapayipi ochungechunge lwe-NPD ungahlukaniswa ube izinhlobo ezimbili: uhlobo lokulawula oluqondile kanye nohlobo lokulawula olungaqondile (uhlobo lokulawula umfutho womoya oyinhlanganisela).
a. Umshini we-jacking wepayipi wokulawula okuqondile ungalawula ukucindezela kokusebenza kwe-tank yamanzi odaka ngokulungisa isivinini sepompo yodaka noma ukulungisa ukuvulwa kwe-valve yokulawula amanzi odaka. Le ndlela yokulawula ilula futhi ifanelekile, futhi izinga lokuhluleka liphansi.
b. Umshini we-jacking wamapayipi wokulawula ngokungaqondile ulungisa ngokungaqondile ukucindezela kokusebenza kwethangi lamanzi anodaka ngokushintsha ukucindezela kwe-tank cushion air. Le ndlela yokulawula inempendulo ebucayi kanye nokunemba kokulawula okuphezulu.
1. I-automatic control air cushion inganikeza ukusekela okunembile kobuso bomhubhe, ukuze kuqinisekiswe ukuphepha kokushayela komhubhe ngezinga elikhulu kakhulu.
2. Umhubhe ungenziwa futhi lapho umfutho wamanzi ungaphezu kuka-15bar.
3. Sebenzisa udaka njengendlela eyinhloko ukulinganisa ukucindezela kokubunjwa endaweni yokumba yomhubhe, futhi ukhiphe i-slag ngokusebenzisa uhlelo lokudlulisa udaka.
4. I-NPD yochungechunge lwe-pipe jacking machine ifaneleka ekwakhiweni komhubhe ngomfutho wamanzi ophakeme kanye nezidingo eziphakeme zokuhlala phansi.
5. Ukusebenza kahle kokushayela okuphezulu, okuphephile nokuthembekile, okunezindlela ezimbili zokulinganisa zokulawula okuqondile nokulawula okungaqondile.
6. I-NPD yochungechunge lwe-pipe jacking umshini onomklamo wekhanda lomsiki othuthukile nothembekile kanye nokujikeleza kodaka.
7. Umshini wokukhipha amapayipi ochungechunge lwe-NPD wamukela i-main bearing, i-main drive seal kanye ne-main drive reducer, enempilo ende yesevisi kanye nesici sokuphepha esiphezulu.
8. Uhlelo lwesofthiwe yokulawula oluzithuthukisayo, ukusebenza kwawo wonke umshini kuphephile futhi kuthembekile, futhi ukusebenza kulula.
9. Inhlabathi ehlukahlukene esebenzayo ebanzi, njengenhlabathi ethambile, ubumba, isihlabathi, inhlabathi ewubhuqu, inhlabathi eqinile, i-backfill, njll.
10. Umjovo wamanzi ozimele, uhlelo lokukhipha.
11. Ijubane elisheshayo licishe libe ngu-200mm ngomzuzu.
12. Ukwakhiwa kokunemba okuphezulu, ukuqondisa mhlawumbe ukuya phezulu, phansi, kwesokunxele nakwesokudla, kanye ne-angle yokuqondisa kakhulu engu-5.5 degrees.
13. Sebenzisa isistimu yokulawula emaphakathi phansi, ephephile, enembile, futhi elula.
14. Uchungechunge lwezixazululo ezenziwe ngomthungi lungahlinzekwa ngezidingo ezahlukene zephrojekthi.
