Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dam engineering, in particular to a dam anti-leakage and anti-seepage device. Background Art
[0002] As an important part of water conservancy projects, the stability and safety of dams are directly related to the safety of people's lives and property and the stable development of the social economy. During long-term operation, dams are often affected by various factors such as water erosion and geological changes, resulting in leakage problems in the dam body. This will not only reduce the dam's flood control capacity, but may also cause serious consequences such as dam instability and dam collapse.
[0003] Traditional dam anti-leakage and anti-seepage devices mainly rely on the principles of physical barriers and material isolation to prevent moisture from penetrating through the dam body. Common traditional anti-leakage and anti-seepage methods include the use of clay core walls, cement grouting curtains and asphalt concrete panels. Clay core walls are often used as the core anti-seepage layer of dams due to their good impermeability and plasticity. Cement grouting curtains form a dense anti-seepage curtain by pouring cement slurry into the interior of the dam body, while asphalt concrete panels have become the preferred material for dam surface anti-seepage due to their high strength and durability.
[0004] However, in the actual use of traditional devices, although the clay core wall can effectively prevent seepage, it is prone to cracks and deformation when the dam body is high. The cement grouting curtain is difficult to form a curtain for anti-seepage under pressurized water conditions. Although the clay core wall has good impermeability and plasticity, long-term immersion may cause the anti-seepage performance to deteriorate. The cement grouting curtain forms an anti-seepage curtain by pouring cement slurry, but the grouting effect may be limited by geological conditions, resulting in loose grouting, thereby forming a potential leakage channel. Therefore, it is necessary to propose a dam anti-leakage and anti-seepage device. Utility Model Content
