[0002] A rail transit tunnel system is a type of construction engineering system used for train passage. It consists of tunnel ducts and support structures, with the ducts connected to the support structures, which are installed on the tunnel concrete structure to allow the ducts to be positioned on the concrete.

[0003] Chinese Patent CN212929153U discloses a prefabricated tunnel seismic support frame, including a suspension platform. Suspension devices are symmetrically arranged at both ends of the top of the suspension platform. Each suspension device includes a corner seat installed on the top of the suspension platform, a main suspension rod installed on the top of the corner seat, and a protruding locking bolt fixed to the top of the main suspension rod. A first load-bearing rod and a second load-bearing rod are respectively connected to the side walls of the corner seat. The main suspension rod, locking bolt, and first load-bearing rod form a triangular structure, providing high installation stability. All three are connected to the tunnel wall at their tops. Each suspension device is connected at three points on the tunnel wall, distributing the suspension pressure from three points in the vertical, horizontal, and front-back directions. This multi-point dispersion of the impact force from vibration improves the seismic performance of the suspension device. Pipelines are placed on the top of the suspension platform, and the outside of the pipelines is clamped by pipe clamps A and B, achieving external clamping of the pipelines and assisting in the suspension installation of pipelines inside the tunnel, thus expanding the function of the suspension platform.

[0004] However, the above technical solutions are only relatively stable for the installation of tubular equipment, and are not convenient for fixing rectangular objects, so the effect is not good enough. Therefore, this utility model proposes a support and hanger structure for rail transit tunnels to solve the above problems. Utility Model Content
