Design concept

Time-saving

The traditional construction period is1 year,and the preinstalled construction period is 2\~3 months,which can shorten the construction period by 7 3 % #

\bigcirc Factory prefabrication,site module assembly,reduce site construction and commissioning.
\bigcirc The precast compartment is convenient to install, saving the construction time of concrete buildings and reducing labor cost.
\bigcirc Plugand play type prefabricated optical cable,prefabricated cable,simple and reliable field wiring.
\bigcirc Flexible layout,not limited by terrain,convenient location, shorten the construction period.

Province

Traditionalwhole stationwall coversanarea of 35o0\~4000 square meters,preinstalledwhole stationwall coversan area of2500\~3oo0 square meters,the area is reduced by 2 5 %

\bigcirc Compared with the traditional concrete building,the preinstalled cabin body reduces thesite land.

\bigcirc Each module in the station can be flexibly arranged according to the terrain,which is lessaffected by the terrain.
