Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection equipment, and in particular relates to an electric heating water leakage hole structure for preventing slope damage caused by freezing and thawing. Background Art

[0002] In slope protection projects, after the water in the cracks of the bedrock seeps out of the slope surface or is discharged through the drainage holes, the discharged water is easy to freeze in winter, which will cause frost heave cracks or uneven deformation of the slope. When the weather warms up, the surface water on the slope begins to melt, but the water inside the slope remains frozen, which can prevent the water from seeping in. The melted water accumulates on the surface of the frozen body, and the strength of the rock layer decreases after weathering. Under the sliding action of gravity and water seepage, the slope becomes unstable and collapses. Utility Model Content
