[0002] A dam is a dike or weir that impounds water from a river, such as a reservoir or a major embankment. A typical reservoir dam consists of a main dam, secondary dams, gravity dams, normal spillways, emergency spillways, newly added emergency spillways, the Lingzheng Canal culvert, and a power station. Dams can be broadly classified into concrete dams and earth-rock dams. The type of dam is selected based on a comprehensive comparison of factors such as the natural conditions of the dam site, building materials, construction area, diversion, construction period, and cost. However, the bottom of a dam is submerged in water for extended periods, and many dams are homogeneous clay dams, which leads to seepage. Over time, excessive seepage at the bottom of the dam can compromise its quality and reduce its waterproofing function. Utility Model Content
