Description

Technical Field

[0001] This utility model relates to the technical field of dam structures, specifically a wave-damping wall structure for hydraulic dams. Background Technology

[0002] In water conservancy engineering construction, wave-damping devices need to be built on dams to prevent water from entering the construction site. Traditional wave-damping devices are generally waterproofed by piling up sandbags. This type of wave-damping device has poor waterproofing effect, its waterproofing performance decreases sharply after long-term use, and it is prone to collapse after being subjected to wind and waves. During the construction of water conservancy projects, wave-damping devices are often needed to protect the dikes. Current wave-damping devices have relatively simple structures and single functions.

[0003] In addition, there is a wave-blocking wall for a hydraulic dam, such as the one with patent publication number CN107245979A, which is composed of several wall units connected together. The wall unit includes a base, a first fence wall, a second fence wall, a third fence wall, and a water-retaining wall. The flow velocity of the water waves gradually decreases under the blocking force of the first fence wall, the second fence wall, and the third fence wall, so as to effectively reduce the impact of the water waves on the water-retaining wall, thereby reducing the probability of the waterproof wall collapsing and improving the waterproof effect of the wall unit.

[0004] However, since a large amount of water inevitably flows in during the wave-damping process, the structure is inconvenient to clean and lacks practicality. Utility Model Content

Screw-fitted: Multiple sets of bottom frames 1 are horizontally distributed at the corresponding wave-blocking positions of the water conservancy dam. Based on the fact that the short trapezoidal wave-blocking wall 8 is located on the outside and the high trapezoidal wave-blocking wall 9 is located on the inside, the mounting bases 7 of the short trapezoidal wave-blocking wall 8 and the high trapezoidal wave-blocking wall 9 are respectively embedded into the inner side of the corresponding mounting frames 4.

Nuts 6 are screwed on the protruding side to fix the short trapezoidal wave-blocking wall 8 and the high trapezoidal wave-blocking wall 9 relative to the bottom frame 1, thereby forming a horizontal arrangement of multiple sets of short trapezoidal wave-blocking walls 8 and high trapezoidal wave-blocking walls 9. During the wave-blocking process, the short trapezoidal wave-blocking wall 8 resists the low-energy water waves at low positions, consuming some energy. Then, the high trapezoidal wave-blocking wall 9 resists the high-energy water waves at high positions, guiding the water downward to the bottom frame 1, and then concentrating it downward through the guide bucket 2, and then draining it back into the reservoir through the drainage pipe 3.

During the wave-blocking process, the short trapezoidal wave-blocking wall 8 resists the low-energy water waves at low positions, consuming some energy. Then, the high trapezoidal wave-blocking wall 9 resists the high-energy water waves at high positions, guiding the water downward to the bottom frame 1, and then concentrating it downward through the guide bucket 2, and then draining it back into the reservoir through the drainage pipe 3.

[0029] It also includes anti-loosening washers 12. Each set of anti-loosening washers 12 is provided at the mounting bolts 5 and nuts 6 on the outside of each set of mounting frames 4.
