Impermeable passage and animal escape device

Abstract

The invention discloses an impermeable passage and animal escape device. The device comprises a slope passage, buoyancy pontoons and a sleeving plate. The buoyancy pontoons are arranged at the bottomof the slope passage. The slope passage is movably connected to the sleeving plate. The impermeable passage and animal escape device provided by the invention are provided with the slope passage withthe slope gradient capable of changing along with change of the water level, can help various types of animals to escape, is of a fabricated structure, is easy to dismantle and install, can protect original bank slope plants of a rural river and also has the advantages of being easy to construct, low in cost and high in practicality.

Description

technical field [0001] The invention relates to an anti-seepage channel and an animal escape device, belonging to the technical field of agricultural engineering. Background technique [0002] At present, in the continuous construction of supporting facilities and water-saving renovation projects in irrigation districts, factors such as improving water delivery efficiency, reducing water delivery losses, structural safety, simple construction, and saving land are mainly considered. Concrete anti-seepage channel lining is an important energy-saving Water measures are widely used. The hardening of irrigation channels has effectively improved the water use coefficient of the canal system and the utilization rate of cultivated land, but it has also become one of the main reasons for the inability of plants to survive, the degradation of aquatic and amphibian habitats, and the loss of agricultural biodiversity. Once livestock, poultry and field amphibians accidentally fall into ...

Problems solved by technology

[0003] Existing relevant application research is still dominated by ecological slope protection technology, mainly focusing on ecological lining forms, new ecological slope protection materials and vegetation engineering slope protection, most of which are to set escape ladders in channel slope protection. This method has obvious disadvantages: 1) Ladder The slope and size of the setting are fixed, and it is impossible to meet the habits of various small animals in the field at the same time, and the actual effect may only meet the escape requirements of one small animal; 2) The construction difficulty and engineering volume of channel reconstruction are increased, making it difficult to popularize and use; 3 ) Lack of comprehensive consideration of factors such as the natural conditions of the irrigation area, the functional orientation of the channel, the living habits of field organisms, the technical feasibility and economic rationality of the ecological restoration project
