Steel feeding bin structure of underground comprehensive pipe gallery

The invention discloses a steel feeding bin structure of an underground comprehensive pipe gallery. The steel feeding bin structure comprises unit pipe joints formed by circumferentially splicing unit plate sheets, wherein a feeding inlet is formed in the unit plate sheet positioned on the top surface; and profile steels for reinforcing an orifice structure and connecting with an external structure are arranged at the periphery of the feeding inlet. According to the steel feeding bin structure disclosed by the invention, orifices for meeting the sizes of pipelines, equipment and person enter/exit are formed in the unit plate sheet positioned on the top surface; and the peripheries of the orifices are reinforced by adopting the profile steels, and laying and maintenance of the pipelines and the equipment inside the pipe gallery are facilitated. 本发明公开了种地下综合管廊的钢制投料仓结构，包括由单元板片周向拼装而成的单元管节，其中位于顶面的单元板片上开设有投料口，该投料口的四周设有用于加固孔口结构和连接外部结构的型钢。本发明在位于顶面的单元板片的表面上开设满足管线、设备、人员进出尺寸的孔口，并在孔口的周采用型钢进行加固，便于管廊内部管线、设备的铺设和维修。
