[0002] Flood control measures for water conservancy projects are very important because they directly affect the safety of people's lives and property and the stable development of society. Floods often lead to chaos in social order and hinder economic development. Effective flood control measures can reduce this unstable factor and ensure the normal operation of society.

River channels are common and important construction sites for water conservancy projects. By building slope protection on both sides of the river channel, it can reduce water loss and maintain the ecology. However, when the flood season comes, the river water level continues to rise due to heavy rain. Before the water level rises to the ground, the river water continuously impacts the slope protection, and the slope protection is generally inclined. The impacting river water flows along the slope protection to the shore and washes away things on the shore, which is not conducive to the escape and rescue work of people on the shore.

[0018] In this implementation scheme: the flood control slope protection 1 supports and provides external protection for each component of the device. The flood control slope protection 1 is set at the slope of the water conservancy river channel. The flood control slope protection 1 shields and protects the river channel slope to reduce soil erosion and maintain ecological balance. The flood control slope protection 1 accommodates a plurality of sliding plates 2 through a plurality of give-way grooves 11. The plurality of sliding plates 2 correspond to the inner diameter size of the give-way grooves 11. A plurality of sliding grooves 12 accommodate the corresponding first shielding plates 3. The first shielding plates 3 support the corresponding second shielding plates 31. The first shielding plates 3 and the second shielding plates 31 shield the impact of the flood season river water to prevent the river water from directly washing onto the river bank, delaying the time for the river water to spread to the ground, and striving for more rescue opportunities. A plurality of sliding plates 2 correspond to a plurality of first shielding plates 3 one by one.

In normal use When the sliding plate 2 is in the sliding groove 12, the sliding plate 2 and the first shielding plate 3 are in the corresponding groove 11 and the slide groove 12. When the river water impacts the slope protection during the flood season, the impacting river water enters the groove 11 and contacts the sliding plate 2. The impact force of the river water is transmitted to the sliding plate 2, and the sliding plate 2 is forced to slide deep into the groove 11.
