Self-anchored template bracket system for connecting channel and construction method

The invention belongs to the technical field of metro construction and relates to a self-anchored template bracket system for a connecting channel and a construction method. A first steel template anda second steel template are spliced by small steel templates which can be repeatedly used, and meanwhile, the radian of a structural arch wall can be also guaranteed and the rigidity also can meet the demand fully. By taking pre-bended I-shaped steel as a main keel and reserving a self-anchoring bar to fix the I-shaped steel when a structural bottom plate is poured, so that the system is stressedwell, a relatively large operation space is released and second lining concrete is poured conveniently. The I-shaped steel is reinforced assisted by a simple bracket and is served as an operating platform of pouring the second lining concrete, the passing condition of operators is good, and meanwhile, the stability of the whole template bracket system is also improved. 本发明属于地铁施工技术领域，涉及一种联络通道自锚式模板支架系统及施工方法，第一钢模板和第二钢模板均为小钢模
