Īmēra, kōrerorero ā-ipurangi rānei kia whiwhi mahere ngaio mo te otinga tohu ngoikore

He kaupapa punaha kapi tohu waea pūkoro mo te 2km te hiko hiko me te waahi mahi hoistway

 Kapi tohu waea pūkoro mo te kauhangaWhakaahuatanga kaupapa:Pūnaha tohu tohu waea pūkoro o Tianjin Electric Power Tunnel, tata ki te 2 kiromita te roa, e 3 nga manga i roto i te kauhanga,

He mea tika ki te uhi i te kauhanga me te waahi mahi hoistway me te kapi tohu tohu-whatunga. I muri i te otinga o te whakaurunga, ka taea te whakatutuki i nga mahi waea noa + uru ipurangi i roto i te kauhanga.

kauhanga

Hoahoa:
1. Ko te tuatahi, i roto i te kauhanga, ka whakamahia te kotahi-ki-rua muka whatu tata-mutunga tukurua + muka whatu tukurua mamao ka whakamahia hei uhi i te kauhanga. Ko ia pito tawhiti ka hono ki nga antenna pereti e rua, ka taea te hipoki i te tawhiti o te 900 mita. No reira, e 2 nga huinga mamao ka taea te 1800 mita te tawhiti. Na te mea he koki koki tetahi wahi o te hiku, ka taapirihia he tukurua ahokore hiko 2W ki te hiku hei taupoki i te waahanga kohanga kopiko i te hiku.
2. Te kapi o te waahi mahi: He iti te waahi o roto o te rakau, a ka taea te whakamahi i te toru o nga kaitahuri hiko 2W hei whakarei ake i te tohu o roto o ia rakau.
