Description

Technical Field

[0001] The utility model relates to the technical field of reservoir bank, and more specifically, the utility model relates to an anti-seepage structure for reservoir bank. Background Technique

[0002] The reservoir bank refers to the shore or shoreline around the reservoir, also known as the reservoir shoreline or reservoir boundary. It is the demarcation line formed between the water surface and the land after the reservoir stores water. The reservoir bank is usually composed of soil, rock or other geological materials, and usually has a certain slope or inclination.

[0003] After retrieval, the existing patent (publication number: CN221218701U) discloses an anti-seepage structure for reservoir bank, including a shore base. One side of the shore base is fixedly provided with a steel mesh cage. The side of the steel mesh cage away from the shore base is fixedly installed with a waterproof geotextile. The side of the waterproof geotextile away from the steel mesh cage is fixedly provided with a sand and gravel mixed layer. A concrete slope protection is cast on the side of the sand and gravel mixed layer away from the waterproof geotextile. An external protection board is fixedly installed on the side of the concrete slope protection away from the waterproof geotextile. A reinforced grouting layer is cast at the position of the steel mesh cage. The waterproof geotextile is directly fixedly connected with the steel mesh cage through a connecting band. A cement mortar bonding layer is arranged between the sand and gravel mixed layer and the concrete slope protection. This application makes the entire reservoir bank have good protection and anti-seepage performance, and improves the service quality and life of the reservoir bank.

[0004] However, there are still certain deficiencies in the above scheme. During the use of the reservoir, when it rains, the water level line of the reservoir will rise. After this time passes, the water level line will drop. However, due to the hysteresis of groundwater, the groundwater flow velocity will slow down, which makes it easier for groundwater to penetrate into the storage room.

[0005] In view of this, the utility model provides an anti-seepage structure for reservoir bank. Content of the Utility Model
