The invention discloses a diversion tunnel water stop copper sheet fixing device which comprises a plurality of adjusting cylinders evenly arranged on the surface of the inner wall of a tunnel, the tops of the adjusting cylinders are fixedly connected to the inner wall of the tunnel through expansion bolts, fixing nuts are fixedly connected to the interiors of the adjusting cylinders, screw rods are in threaded connection with the interiors of the fixing nuts, and water stop copper sheets are connected to the bottoms of the screw rods. And the plurality of water stop copper sheets are mutually connected and combined to form an arc-shaped structure. The mounting holes are uniformly formed in the inner wall of the tunnel, then the expansion bolts are fixed in the mounting holes, then the adjusting cylinders and the water stop copper sheets are sequentially mounted at the bottoms of the expansion bolts, and when the water stop copper sheets are welded, the distances between the water stop copper sheets and the inner wall of the tunnel can be adjusted by rotating the screws, so that the water stop copper sheets can be aligned with one another; and welding work can be efficiently carried out conveniently, and the sealing performance of the water stop copper sheet is improved.
Description
technical field [0001] The invention relates to a water-stop copper sheet fixing device for a diversion tunnel, belonging to the technical field of engineering construction. Background technique [0002] The diversion structure is mainly composed of horseshoe-shaped and circular diversion tunnels. During the lining construction of the diversion tunnel, it is usually necessary to use wooden fixed formwork to fix multiple water-stop copper sheets inside the tunnel in advance, and then splice and weld multiple water-stop copper sheets. Together, they form an arc-shaped copper water-stop layer, and then install a detachable formwork and pour concrete, so that the water-stop copper sheet is fixed inside the concrete. [0003] In the prior art, in the construction technology of the concrete lining buried pipe method at the bottom of a circular tunnel, high-flow, self-compacting pumped concrete is used, and a steel pipe device is buried at the bottom of the tunnel, and the concrete...
