Feed bin and connection structure of standard cell tube coupling and utility tunnel of cross -section change

The utility model discloses a feed bin and connection structure of standard cell tube coupling and utility tunnel of cross -section change, utility tunnel is assembled along circumference by the unit slab and is formed the standard cell tube coupling, and the formation piping lane is assembled along the axial to this unit tube coupling, on this piping lane along the axial be separated by be equipped with with the standard cell tube coupling inconsistent feed bin in cross -section, the transition section through the cross -section change between this feed bin and the standard cell tube coupling is connected. The utility model discloses a connection between standard cell tube coupling and the feed bin has been realized to the transition section of this variable cross section, has solved steel construction utility tunnel variable cross section and has been difficult to the technological problem that the realization links up. 本实用新型公开了种投料仓与标准单元管节的连接结构及截面变化的综合管廊，所述综合管廊由单元板片沿周向拼装形成标准单元管节，该单元管节沿轴向拼装形成管廊，该管廊上沿轴向相隔设有与标
