Monorail beam support and shield segment connecting structure and construction method thereof

The invention discloses a monorail beam support and shield segment connecting structure and a construction method thereof. The construction method of the monorail beam support and shield segment connecting structure comprises the steps of shield segment preparation, shield segment splicing, base construction, drainage ditch construction, cast steel support construction and rail beam mounting, wherein shield segments are prepared, specifically, expansion bolts and high-strength bolts are pre-embedded on the inner side of the shield segments; and the shied segments are spliced, specifically, steel plates are mounted on the inner sides of the shield segments through the high-strength bolts, and meanwhile, the steel plates and the expansion bolts are in welded connection. The steel plates arearranged on the inner sides of the shield segments and connected with and fixed to the pre-embedded expansion bolts and high-strength bolts, L-shaped steel plates are mounted during base construction,the L-shaped steel plates
