5. Ntchito yomanga mpweya wabwino
Pa Novembala 27, 2009, kuyesa kwa mpweya wabwino kunachitika pakutsegula kulikonse, ndipo mphamvu ya mpweya ya nkhope iliyonse yogwira ntchito inali yabwino. Kutengera fanizo la 10 lopendekera mwachitsanzo, malo omangawo adagwiritsa ntchito nkhope 4 zogwirira ntchito nthawi imodzi, ndipo mpweya wabwino unakumana ndi ukhondo ndi chitetezo chamsewu wamapiri a alpine. Miyezo yoyendetsera chilengedwe, zotsatira zoyezedwa zikuwonetsedwa mu Gulu 5.

6. Mapeto
6.1 Msewu wa Guanjiao pakali pano ndiye msewu wautali kwambiri wamapiri womwe ukumangidwa ku China. Imakumana ndi zovuta zazikulu zaukadaulo pakuwongolera mpweya womanga pamalo okwera, mtunda wautali, ndi nkhope zingapo zogwirira ntchito. Miyezo ya mpweya wabwino yomwe ikugwiritsidwa ntchito m'maiko osiyanasiyana padziko lapansi nthawi zambiri imakhala pakati pa 3 ndi 8m3/(kW·min). Malinga ndi momwe zinthu zilili m'dziko langa, kukhazikitsidwa kwa miyezo yaukhondo pomanga ngalande zapamwamba za Guanjiao akufunsidwa.
6.2 Malinga ndi mafomu osiyanasiyana omanga bungwe omwe akhazikitsidwa mu Tunnel ya Guanjiao, kudzera mu kafukufuku wofufuza mwadongosolo komanso mayeso am'munda, mpweya wabwino wokhazikika komanso mpweya wosakanikirana wa msewu wokhotakhota wa shaft clapboard akufunsidwa, womwe umathetsa vuto la mpweya wabwino. Ntchito yomanga ngalande yayitali yapeza ntchito yabwino.
6.3 Nkhope zinayi zogwirira ntchito za Line 1 ndi Line II zimagwiritsidwa ntchito pomanga shaft yokhotakhota pomanga ngalande yabwino nthawi imodzi. Zotsatira zoyesa zikuwonetsa kuti mpweya wabwino wa nkhope iliyonse yogwira ntchito ndi yabwino, komanso mpweya wabwino umakwaniritsa miyezo ya mpweya wabwino.
