[0008] By adopting the above technical solution, before installing the first fish nest and the second fish nest on the slope protection, the first fish nest and the second fish nest are first fixedly connected by a connecting pipe, and then the first fish nest and the second fish nest connected up and down are inserted into the embedded column together, so that the embedded column passes through the second fish nest, the connecting pipe and the first fish nest in sequence, and the first fish nest and the second fish nest are preliminarily positioned, and then the first fish nest is fixed on the bottom wall of the river channel by a connecting piece, and the first fish nest is stably supported by a supporting piece, and finally the first fish nest and the second fish nest are fixed on the vertical slope surface of the slope by a fixing assembly, so that the stability between the first fish nest and the second fish nest and the slope is greatly increased.

[0009] Optionally, the support member and the connecting member are both nuts, the side wall of the embedded column located at the top of the first fish nest is threaded, the bottom side wall of the embedded column located in the second fish nest is threaded, the connecting member is threadedly connected to the embedded column and presses the second fish nest to the bottom wall of the river channel, the support member is threadedly connected to the embedded column and pressed against the top wall of the first fish nest, and the outer walls of the support member, the connecting member and the embedded column are all coated with waterproof coating.
