ITekhnoloji yokuPhumelela kweVentiyelo yoLwakhiwo lweTonela yoMphakamo oMde

1. Isishwankathelo seProjekthi yeTunnel yaseGuanjiao

Itonela laseGuanjiao likwiNqila yaseTianjun, kwiPhondo laseQinghai. Yiprojekthi yolawulo lwe-xining -Igolideumgca wokwandisa weQinghai-Tibet Railway. Itonela yi-32.6km ubude (umphakamo we-inlet yi-3380m, kwaye umphakamo wokuthumela ngaphandle yi-3324m), kwaye yimijelo emibini ehambelanayo kunye nesithuba somgca wama-40m. Ubushushu bonyaka bonyaka kulo mmandla ngu -0.5℃, obona bushushu buncinci bugqithileyo yi -35.8℃, ubushushu obuphakathi kweyona nyanga ibandayo yi -13.4 ℃, obona bunzima bekhephu bungama 21cm, ubunzulu bekhephu bungama 299cm. Ummandla we-tunnel yi-alpine kunye ne-hypoxic, uxinzelelo lwe-atmospheric luyi-60% -70% kuphela yoxinzelelo oluqhelekileyo lwe-atmospheric, umxholo we-oksijini womoya uyancipha malunga ne-40%, kunye nokusebenza koomatshini kunye nabasebenzi kuyancipha kakhulu. Itonela yakhiwe ngendlela yokugaya kunye nokuqhushumba, kunye ne-10 yothutho olungenamkhondo i-shafts inclined shafts isetyenziselwa ukuncedisa ukwakhiwa kwe-tunnel enkulu, oko kukuthi, i-3 inclined shafts ibekwe kwi-tunnel yomgca we-I kunye ne-7 i-shafts inclined shafts ibekwe kwi-tunnel yomgca we-II.

Ngokutsho koyilo lombutho wokwakha, ilungiselelo lomsebenzi wokungena kwe-tunnel kunye nokuphuma kunye nendawo yokusebenza ye-shaft inclined iboniswe kwiThebhile 1. Ukuqwalasela utshintsho kunye nohlengahlengiso kulwakhiwo lwangempela, indawo yokusebenza ye-shaft ethambekeleyo ineemfuno zokwakhiwa ngaxeshanye kwendawo yokungena kunye nokuphuma komgca I kunye nomgca we-II. Ubude obuphezulu bentloko enye yokungenisa umoya kufuneka bube yi-5000m, kwaye umphakamo wendawo yokusebenza kufuneka ube malunga ne-3600m.
