Seepage-proofing and water-stopping structure for water conservancy and hydropower engineering

ZHOU KAILI / LIU HONGLU / GUO YUE

The invention provides a seepage-proofing and water-stopping structure for a water conservancy and hydropower engineering, relates to the technical field of water conservancy project construction, and aims to solve the problems that a sealing structure of an existing seepage-proofing and water-stopping structure is not perfect enough, and cannot be changed in real time according to the change of the water level when river water rises tide, so that the anti-seepage and water-stop effect is not ideal enough. The seepage-proofing and water-stopping structure comprises a mounting part, a rear fixing assembly is arranged at the lower end of the mounting part, and a fixing piece of the fixing assembly is fixed into the mounting groove through a bolt. When the water level in the river rises, inserting blocks drive a moving plate to slide upwards under the action of the buoyancy of the river water, the moving plate moves upwards and blocks a rectangular through hole in the middle of a main plate so as to prevent the river water from permeating into the dam through the rectangular through hole in the middle of the main plate, and through the design, the moving plate can be automatically adjusted according to the water level of the river water, the device is more flexible to use, and the seepage-proofing and water-stopping effects are better.

本发明提供用于水利水电工程上的防渗止水结构，涉及水利工程建造技术领域，以解决现有的防渗止水结构的密封结构不够完善，在河水涨潮时，无法根据水位的变化来实时进行改变，使得防渗止水效果不够理想的问题，包括安装部；所述安装部下端设有后固定组件，且固定组件的固定件通过螺栓固定到安装槽内。当河内水位升高时，插块受河水浮力的作用，带动移动板向上滑动，移动板向上移动并堵住主板中间的矩形通孔，以防止河水透过主板中间的矩形通孔渗入堤坝内，通过这样设计，可使移动板根据河水的水位进行自动调节，使得本装置使用起来更加灵活，使防渗止水效果更好。
