All other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model. It should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", etc. is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the utility model and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0023] Example 1
[0024] like Figure 1 , Figure 2 As shown, this embodiment provides an ecological life-saving ladder for a river retaining wall, including a plurality of pedals 3 and a filter layer 4. The plurality of pedals 3 are arranged at intervals on the concrete retaining wall 1, and a drainage channel is provided between two adjacent pedals 3. The drainage channel extends into the concrete retaining wall 1, and a filter layer 4 is provided between each two adjacent pedals 3. The filter layer 4 is arranged corresponding to the drainage channel, and the filter layer 4 is arranged inside the drainage channel. The upper end of the pedal 3 protrudes from the filter layer 4.
