Temporary supporting structure for solving conflict between shield hole boundary beam of middle plate of subway station and shield

The temporary supporting structure system comprises a subway station structure, buttress columns are arranged on the end wall of the subway station structure, the station structure middle plate shield hole boundary beam conflicting with a shield area is lifted to avoid the shield area, and after lifting, the subway station structure middle plate shield hole boundary beam conflicting with the shield area is supported by the buttress columns. The shield hole boundary beams, the end walls and the buttress columns bear horizontal loads together; meanwhile, a temporary horizontal force transmission component and a supporting bracket are vertically arranged at the position of a side beam of a shield hole after lifting, horizontal loads are transmitted to a middle plate and a middle longitudinal beam which are large in rigidity, and a complete and reliable structure stress system is formed; after shield construction is completed, the temporary force transmission component is cut off in a static force cutting mode, t
