Embodiment 1

[0013] as attached figure 1 As shown, the anti-seepage and water-proof structure on the water conservancy project described in the present embodiment is mainly used for breakwater dams in coastal areas, which includes a dam body 10, and on one side of the water-retaining surface of the dam body 10, a structure extending from the dam crest is provided. To the stepped dam anti-seepage layer 20 at the bottom of the dam; the dam foundation anti-seepage layer 40 is arranged in the dam foundation at the bottom of the dam body; and between the dam foundation anti-seepage layer 40 and the stepped dam body anti-seepage layer 20 The anti-seepage connection layer 30 ; the anti-seepage layer 40 of the dam foundation is a combined structure of a concrete anti-seepage wall 41 and a grouting curtain 42 . Wherein, the anti-seepage connection layer 30 is a reinforced concrete plinth, a reinforced concrete connection plate or a reinforced concrete base.

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...
