1. Isishwankathelo seProjekthi yeTunnel yaseGuanjiao
Itonela laseGuanjiao likwiNqila yaseTianjun, kwiPhondo laseQinghai.Yiprojekthi yolawulo lwe-xining -Igolideumgca wokwandisa weQinghai-Tibet Railway.Itonela inobude obungama-32.6km (umphakamo wokungena yi-3380m, kwaye umphakamo wokuthumela ngaphandle yi-3324m), kwaye ziitonela ezimbini ezithe tye ezingqameneyo ezinesithuba somgca wama-40m.Ubushushu bonyaka bonyaka kulo mmandla ngu -0.5 ℃, obona bushushu buncinci bugqithileyo ngu -35.8℃, ubushushu obuphakathi kweyona nyanga ibandayo yi -13.4 ℃, obona ngqindilili 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, kwaye i-10 yezothutho ezingenamkhondo zisetyenziselwa ukuncedisa ukwakhiwa kwetonela eliphambili, oko kukuthi, i-3 inclined shafts ibekwe kwitonela yomgca we-I kunye ne-7 shafts ethambekele ebekwe kwitonela. yomgca II.
Ngokutsho koyilo lombutho wokwakha, ilungiselelo lomsebenzi wokungena kwetonela kunye nokuphuma kunye nendawo yokusebenza ye-shaft ethambekeleyo iboniswe kwiThebhile 1. Ukuqwalasela utshintsho kunye nohlengahlengiso kulwakhiwo lwangempela, indawo yokusebenza ye-shaft ethambekeleyo nganye ineemfuno zokwakhiwa kwangaxeshanye kwindawo yokungena kunye indawo yokuphuma yomgca I kunye nomgca we-II.Obona bude buphezulu bentloko enye bufanele bube yi-5000m, kwaye umphakamo wendawo yokusebenza kufuneka ube malunga ne-3600m.
Iza kuqhubeka…
