Description
Technical Field
[0001] The utility model relates to the technical field of concrete dam reinforcement, in particular to a reinforcement device for a concrete dam. Background Art
[0002] At present, concrete dams are water-retaining structures that intercept water flows in rivers and channels to raise water levels or regulate flow. Reservoirs can be formed to raise water levels, regulate runoff, concentrate water heads, and are used for flood control, water supply, irrigation, hydropower generation, and improved navigation. River regulation structures that adjust river flow and protect the bank bed are also called dams, such as spur dams, spur dams, and submerged dams. In reinforcement projects, according to the actual conditions of different dams, force methods such as dam surface treatment, grouting treatment, post-dam reinforcement, and pre-dam reinforcement can generally be used. During the long-term operation of the concrete dam, cracks often occur under various loads, and reinforcement treatment is required to affect the safety of the dam. When the existing reinforcement device is in use, the side of the device that contacts the dam on the inside is horizontal and vertical. When the dam surface is tilted and non-vertical, the dam cannot be supported. Most dams are built in a trapezoidal shape with narrow top and wide bottom in order to increase the force strength of the dam throughout the day. They cannot be used in most cases and have a small scope of application.
