Description

Technical Field

[0001] The utility model relates to the technical field of earth embankment wave-breaking walls, in particular to a wave-breaking slope embankment. Background Art

[0002] In the construction of water conservancy dam projects, wave-breaking walls are often the preferred engineering measure to meet the requirements for super-elevated flood control at the embankment or dam crest while minimizing the embankment design cross-section to further save project investment. Furthermore, with the increasing scarcity of land resources in recent years, the construction or widening and reinforcement of slope embankments is often constrained by land use red lines and permanent basic farmland, making land acquisition and resettlement difficult and challenging to implement. Wave-breaking walls are urgently needed to alleviate the conflict between embankment construction and land acquisition and resettlement, and to address land use quota issues.

[0003] At present, in engineering design, in order to meet relevant requirements, the net height of the wave-breaking wall above the top of the embankment should generally not exceed 1.2m. However, when the flood storage area is receiving water or storing water in lakes, it is significantly affected by wind and waves, and its calculated flood control superelevation value is usually large, which leads to a certain conflict between the height of the wave-breaking wall and the flood control superelevation. The traditional approach is to open a single deep arc surface or multiple continuous inner arc surfaces on the water-facing side of the wave-breaking wall, and to take measures such as wave-blocking ridges and wave-breaking boards. Under the premise of maintaining the wall height not exceeding 1.2m, the wave water body can be rewound and reflux to reduce the amount of overtopping. In engineering practice, the above measures are complex in process, difficult to set up templates, and difficult to implement. The complexity of the structure also usually leads to an increase in the size of the wave-breaking wall, which invisibly increases the project cost.

[0004] Sloping embankments, while fulfilling flood control and security tasks, often serve as production and living passages for local residents. Multiple access roads are often arranged along the embankment line, and gaps are formed at the intersection of the access roads and wave-breaking walls, affecting flood control safety. The traditional approach is to add steel gates and gatehouses at the crossings, and equip them with corresponding door lifting devices and electromechanical equipment, which can effectively achieve the purpose of closing the gates for flood control during the flood season and opening the gates for passage during the non-flood season. In engineering practice, because the duration of wind and wave action during the flood season is generally short, and the elevation of the intersection of the access road and the embankment top is usually higher, the wave climb near the crossing section will be significantly weakened, and there is no need to set up complex wave-proof and water-retaining facilities, which will increase unnecessary project investment and implementation difficulty, and is not conducive to subsequent operation management and maintenance.

[0005] In addition, traditional wave-breaking wall construction is mostly limited to the wave-breaking effect of the wall itself, and does not fully consider the organic combination of traffic safety of the embankment road, road drainage and water conservancy projects, resulting in the wave-breaking wall having a single function and poor overall benefits.

[0006] In summary, it is of great significance to explore a new type of slope embankment wave-breaking wall structure that can integrate the functions of reducing wind and waves, road drainage and facilitating traffic, and has a simple structure, low implementation difficulty and low engineering cost.
