Embodiment
[0039] A method for laying steel frames in the middle wall of a multi-arch tunnel. Independent steel arch structures are respectively arranged in the double holes of the multi-arch tunnel. The steel arch structures of the leading hole and the rear hole are staggered and independently arranged. Pre-embed the lower steel frame on the side close to the common side wall of the rear tunnel into the shared side wall of the first tunnel. fixed to form a complete rear tunnel steel arch structure.
[0040] The steel arch structure includes an upper steel frame, a middle steel frame, a lower steel frame and an inverted arch steel frame. The steel frame is processed and formed outside the hole according to the design requirements, and the installation in the hole is carried out after the primary sprayed concrete. In order to ensure the overall stability and effectiveness of the steel frame, the steel frame is connected with the positioning tie bars and anchor rods during installation. W...
