Technical Field

[0001] This application relates to the field of flood disaster training ground design, and in particular to a slope descent hazard training ground layout structure. Background Technology

[0002] Floods are a type of natural disaster with great destructive power. When floods occur, various dangerous situations can arise, such as dam slippage, which is a common danger in floods. In actual disasters, dam slippage can have a significant impact on dams, and in severe cases, it may lead to dam failure. Therefore, training on dam slippage is very necessary. However, existing flood disaster training grounds do not have a dedicated dam slippage training structure. Summary of the Invention

The main dike is constructed according to the actual Class 3 dike standard. The main dike has water-facing and backwater-facing slope protection designed respectively. The slope detachment drill section is located on the backwater side of the main dike and is constructed using a layered filling method. A weak slip surface is set along the seepage line of the dike in the slope detachment drill section. The toe of the dike or the bottom of the weak slip surface is sealed with clay. A thick sand layer is set at the bottom of the weak slip surface. The water supply system is located inside the main dike. Two main water inlets are set on the water-facing side of the main dike. A branch pipe passing through the dike is connected to the main water inlets. A distribution pipe is connected to the end of the branch pipe and connects to the top of the weak slip surface.

[0006] The main body of the dike is designed with a concrete slope protection on the water-facing side, while the back side is natural soil.

[0007] A dam structure is installed below the water-facing slope of the main body of the dike, and the main water inlet pipe is arranged inside the dam structure.

[0008] The thick sand layer extends from the clay backfill layer at the top of the backwater slope to the clay toe at the bottom of the backwater slope, and the soft slip surface above the thick sand layer is a loam backfill layer.

[0009] The thick sand layer is wrapped with a geomembrane.

[0010] The first corner of the thick sand layer has an angle of 55.09°, and the second corner has an angle of 28.52°.

[0011] Compared with existing technologies, the beneficial effects of this application are: This application achieves a realistic simulation of dike slope failure, allowing for artificial control over the timing of such failures. It provides a realistic and controllable practical scenario for dike slope failure emergency training, effectively improving the practical skills of emergency rescue personnel and enhancing their ability to respond to slope failures.
