Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically to a concrete grid slope protection structure for a counterweight dam. Background Technology

[0002] Slope protection engineering has significant application value in fields such as water conservancy, transportation, and construction. Especially in projects like reservoirs, rivers, and landfills, slope stability directly affects the safety and service life of the project. Traditional slope protection structures typically employ concrete revetments and retaining walls. However, under certain complex geological conditions, particularly in soft foundations or high-water environments, these structures often suffer from insufficient stability, poor anti-sliding performance, and susceptibility to erosion.

[0003] In recent years, with the advancement of engineering technology, the concrete grid slope protection structure for counterweighted dams has been gradually applied in slope protection engineering. This structure improves the anti-sliding stability of the dam by increasing its self-weight, while simultaneously enhancing the slope's resistance to erosion through the concrete grid slope protection structure. However, existing concrete grid slope protection structures for counterweighted dams still have some shortcomings in practical applications:

[0004] 1. Insufficient structural integrity: Existing reinforced concrete grid slope protection structures for ballast dams are usually constructed in layers, and the connections between the layers are not tight enough, resulting in poor overall structural stability and anti-sliding performance. Especially under conditions of flash floods and localized heavy rainfall, local instability or sliding is likely to occur.

[0005] Limited resistance to erosion: Although traditional concrete slope protection structures have a certain resistance to erosion, under long-term water flow and rainwater erosion, the slope surface is prone to cracking and peeling, which affects the durability and safety of the structure.

[0006] Inadequate slope protection for landfill dams: In special projects such as landfills, the protection of landfill dam slopes is particularly important. Existing slope protection structures offer relatively simple protection measures for landfill dam slopes, lacking effective reinforcement and protection methods, which can easily lead to erosion, cracking, or even collapse of the landfill dam slopes.

[0007] Therefore, we propose a concrete grid slope protection structure for counterweight dams to address the problems mentioned above. Summary of the Invention

[0008] The purpose of this utility model is to provide a concrete grid slope protection structure for a counterweight dam to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a concrete grid slope protection structure for a counterweight dam, comprising: a silty clay layer, a reinforced concrete toothed wall, a counterweight dam body facing, a counterweight dam body, a counterweight dam top facing, and an original garbage dam body facing. The reinforced concrete toothed wall is cast in place with concrete and has a trapezoidal cross-section, extending into the toe of the counterweight dam.

[0010] The silty clay layer was rammed onto the original dam bottom, and the counterweight dam body was rammed onto the silty clay layer and the original dam slope. A counterweight dam body revetment was set on the counterweight dam body.

[0011] The ballast dam face and the reinforced concrete toothed wall are cast integrally;

[0012] The ballast body dam crest revetment is set on the original dam slope and located at the upper end of the ballast body dam revetment.

[0013] Preferably, the ballast dam revetment is in the form of a diamond-shaped grid, and turf is planted within the grid of the ballast dam revetment.

[0014] Preferably, the dam crest facing of the counterweight body is made of cast-in-place concrete in a rectangular grid pattern, and a base plate is cast at the bottom.

[0015] Preferably, the original garbage dam revetment is set on the original dam slope and located at the upper end of the ballast dam revetment. The original garbage dam revetment and the ballast dam top revetment are manufactured in the same way and have the same structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The ballast dam body revetment and reinforced concrete toothed wall are cast in one piece to increase the stability and anti-sliding performance of the dam body. The ballast dam body revetment is in the shape of a diamond grid, and the reinforced concrete toothed wall provides the foundation bearing capacity for the ballast dam body revetment.

[0018] 2. The dam crest revetment of the dam with a counterweight structure can protect the dam crest from erosion by rain and flood. The dam crest of the counterweight dam is subjected to more uniform stress, with less structural deformation and stronger structural bearing capacity.

[0019] 3. The original garbage dam revetment will reinforce and protect the original dam slope to prevent erosion, cracking, and collapse. The original garbage dam revetment will connect the original garbage dam body to the dam body of the counterweight dam, strengthening the structural integrity and stability of the two, further improving the engineering function of the counterweight dam and the slope stability of the original garbage dam.
