Abstract

The invention relates to an impermeable water stopping structure for hydraulic engineering. The impermeable water stopping structure comprises a dam body. One side of the water stopping face of the dam body is provided with a step-shaped dam body impermeable layer extending from the dam top to the dam bottom. A dam foundation impermeable layer is arranged in a dam foundation of the bottom of the dam body. An impermeable connecting layer is arranged between the dam foundation impermeable layer and the step-shaped dam body impermeable layer. The dam foundation impermeable layer is of a combined structure comprising a concrete impermeable wall and a grouting curtain. One side of the water stopping face of the dam body is provided with the step-shaped dam body impermeable layer extending from the dam top to the dam bottom, and therefore permeating, washing and wearing of the surface of the dam body from water can be effectively prevented. As the dam foundation impermeable layer is arranged in the dam foundation, the impermeable water stopping structure can effectively prevent seepage of water in a dam, and therefore the impermeability and the durability of the whole dam and the foundation can be ensured.

Description

technical field

[0001] The invention belongs to the technical field of seepage prevention and water prevention, and more specifically, the invention relates to a seepage prevention and water prevention structure applied in rockfill dam engineering. Background technique

[0002] A dam is a water-retaining structure that intercepts the water flow of a river channel to raise the water level or regulate the flow. The purpose of building a dam is mainly to raise the water level, regulate the runoff, concentrate the water head, and use it for flood control, water supply, irrigation, hydroelectric power generation, and improvement of navigation. In addition, river regulation structures that adjust the river regime and protect the bank bed are also called dams, such as spur dams, shun dams, and submerged dams.

[0003] The use of local materials to build dams has a long history. It has the advantages of local materials, low requirements on geological conditions, simple construction...
