Background technique

In water conservancy projects, the setting of ecological slope protection can protect the water and soil on the slope of the canal, and planting vegetation on the slope protection can improve the visual effect. Therefore, in the construction of most water conservancy projects, ecological slope protection will be set up on both sides of the canal. The existing ecological slope protection is made of splicing and combining prefabricated blocks, and vegetation is planted in the prefabricated blocks, so that the soil on the slope surface can maintain the stability of the soil under the joint action of prefabricated blocks and vegetation, but it cannot collect excess water. Prefabricated There is also a risk of erosion of the soil within the block.

The inside of the delivery box is provided with a planting area and a delivery area. A water reservoir is provided on the left side of the delivery box. With filter cover. It can effectively reduce the erosion of the water body on the slope and enhance the water storage performance of the ecological slope protection. When storing water, the reservoir collects the upper rainwater, and the planting pond and the delivery box filter the rainwater. However, plants are planted in the planting pond and the delivery box, and the rainwater needs to be filtered downward through the planting soil to enter the delivery area. In the case of a large amount, the rainwater that has not been fully filtered will collect downwards to the protective plate, causing the vegetation at the planting column to be submerged, which is not conducive to the growth of plants on the downstream slope. The filter cover and lifting rod installed in the reservoir need to be cleaned and maintained after long-term use, and the cover plate and filter box need to be dismantled and installed, which is inconvenient to operate; and the connection form of this device is mostly a snap connection, which is complex in the overall structure In some cases, this snap connection weakens the firm performance of the overall structure.
