Description

Prefabricated assembled type channel biological escape passage

Technical Field

The invention relates to a farmland water conservancy facility, in particular to a biological escape channel applicable to an assembled channel.

Background

China is a water-deficient country, the requirement of farmland water delivery efficiency is considered, the water supply efficiency index is mainly considered in the design of the conventional irrigation and drainage channel, and the channel engineering mostly adopts a concrete lining structure. The vertical revetment and the ditch face with three smooth surfaces and no pores are capable of improving the water delivery efficiency, molding a monotonous and changeless water flow form, separating a connection channel between a water area and a land area in the ditch, preventing small animals from coming in and going out, trapping a large number of frogs at the bottom of the ditch when the irrigation area ditches go back in autumn every year, preventing escape and seriously influencing the biodiversity and ecological integrity of the irrigation area. And the research on the biological escape passage is less, and the assembled component can not meet the escape requirement from the biological water area to the land area.

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.
