U-shaped tunnel and comprehensive pipe gallery shared structure and deformation control method thereof

The invention discloses a U-shaped tunnel and comprehensive pipe gallery shared structure and a deformation control method thereof. The U-shaped tunnel and comprehensive pipe gallery shared structure comprises a cast-in-situ bored pile, a first steel pipe support, a second steel pipe support, a triangular supporting frame and a round steel lifting hook. The U-shaped tunnel side wall and the shared structure have the beneficial effects that the U-shaped tunnel side wall and the shared structure are small in deformation and high in stability, the two-way stress supports can resist lateral soil pressure through pre-added axial force, and displacement of the U-shaped tunnel side wall towards the interior of a tunnel is reduced; and the protection effect on adjacent old dangerous buildings is good. The second steel pipe support of the pipe gallery foundation pit is arranged at the top of the pipe gallery structure, the second steel pipe support is not dismantled in the pouring process of a pipe gallery top plate,
