Connecting corridor combined type steel silo and construction method thereof

The invention provides a connecting corridor combined type steel silo and a construction method thereof. A tradition thermal insulating steel silo is provided with a plurality holes in the roof of thesilo, many thermal bridges are included, temperature rising of the roof of the silo is quick, and gas tightness is difficult to deal with; and conveying equipment and inspection work are subjected tothe open-air roof of the silo, comfortableness of the working environment is poor, no windbreak and rain sheltering facilities are provided, all equipment are subjected to outdoor service and are likely to corrosion, and the service life is reduced. The connecting corridor combined type steel silo comprises a group of steel silo bodies (1), each steel silo body comprises a silo wall plate (21) and a vertical bar (22), each vertical bar is connected with a rigid ring, and each rigid ring is fixed on a structure frame (2); a working table (3) is mounted on the upper part of each structure frame, and each steel silo body
