The invention has the following advantages and beneficial effects:
1. the prefabricated assembled canal biological escape channel is a biological channel structure suitable for amphibians and reptiles to migrate between a water area and a land area, solves the problem that a irrigation and drainage channel cuts off a communication channel between the water area and the land area in a canal, and small animals cannot go out, and is beneficial to protecting biological diversity and ecological integrity of an irrigation area.
2. The prefabricated assembled type canal biological escape channel is formed by integrally pouring concrete, does not need assembly and post-processing, has good structural integrity, large self weight, good stability, easy installation and low cost, and can be directly used as a filling and draining channel; the method can be prefabricated in factories, and the quality is easy to control; the connection with the existing rectangular channel is convenient, and the construction is simple and convenient.
The invention is suitable for biological escape passages of the canals.
