AI Technical Summary
In existing water conservancy and hydropower projects, seepage prevention structures suffer from problems such as sandbags accumulating at the bottom of the guide plate, difficulty in adjustment, and easy loosening and corrosion of motor cylinders, leading to increased structural costs and poor seepage prevention effects.
The design employs multiple mounting rails and caps, which are inclined along the water-facing side of the dam. The caps can selectively fasten to flood control sandbags and are fixed by anchor bolts to prevent sandbag accumulation. They can also be flexibly replaced using chutes and fasteners, eliminating the need for components such as motors and cylinders.
This system enables phased fixing and flexible replacement of flood control sandbags, reducing usage costs, improving seepage prevention, and preventing sandbag accumulation and component loosening and corrosion.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to a seepage-proof structure for water conservancy and hydropower construction. Background Technology
[0002] In the construction of water conservancy and hydropower projects, seepage prevention is a crucial issue. Failure to effectively prevent seepage not only affects the quality and safety of the project but can also lead to water waste and environmental damage. The base of dams is often submerged for extended periods, and many dams are made of homogeneous clay, making them prone to seepage. Over time, excessive seepage at the base of the dam will compromise its quality, significantly reducing its waterproofing function and posing a serious threat to the lives and property of people downstream.
[0003] Patent CN222161102U discloses a seepage-proof and water-stopping structure for water conservancy and hydropower projects. This patent effectively protects the dam from seepage by adding flood control sandbags at the dam and using a flood control sandbag pressing mechanism, a pressing and guiding mechanism to press the sandbags more tightly.

Sandbags tend to accumulate at the bottom of the guide plate, making it difficult to adjust the guide plate. Moreover, when a single sandbag is damaged, it is difficult to replace it. Secondly, the application involves components such as motors and cylinders. Neither motors nor cylinders can be kept in a fixed position for a long time.
