Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0018] Such as figure 1 , 2 As shown, the bionic cave for protecting beavers of the present invention is built in the river 15 on the bank, and includes an ellipsoidal crown-shaped concrete base 1 and a reinforced concrete shell structure roof 8, and the surface of the ellipsoidal crown-shaped concrete base 1 is formed from the bottom to the bottom. The upper layer is evenly covered with the lower polyurethane thermal insulation layer 2 and the lower clay layer 3, the ellipsoidal crown-shaped concrete base 1 and the reinforced concrete shell structure roof 8 form an entrance 4 and two escape passages 5, and an entrance 4 and two escape routes. The escape routes 5 are all submerged in the river 15, and the bionic bed 13 is built on the lower clay layer 3 at the top of the ellipsoidal crown-shaped concrete base 1, and hay 14 is laid in the bionic...

Abstract

The invention discloses a bionic cave for protecting beavers. The bionic cave is constructed in shore river water and comprises an ellipsoidal crown-shaped concrete base, the surface of the ellipsoidal crown-shaped concrete base is covered with a polyurethane heat preservation and insulation layer and a clay layer, the ellipsoidal crown-shaped concrete base is provided with an inlet and two escapeways, the inlet and the two escape ways are immersed in the river water, a bionic bed is built on the clay layer of the ellipsoidal crown-shaped concrete base, a polyurethane heat preservation and insulation layer and a clay layer are sequentially arranged on the inner side of the hole top reinforced concrete shell structure, dead wood branches for hiding a hole are arranged on the outer surfaceof the hole top reinforced concrete shell structure, a ventilation opening is formed in the center of the top of the hole top reinforced concrete shell structure, three lighting channels are evenly distributed on the periphery, and lighting glass is arranged on the lighting channels. The bionic cave for the beavers is simple in type, capable of creating a beaver habitat, long in service life, highin safety coefficient, beneficial to increase of the beaver livelihood industry and the population number and beneficial to national first-level animal beaver protection.

Description

technical field [0001] The invention relates to protecting beavers, in particular to a bionic cave for protecting beavers. Background technique [0002] The beaver (scientific name: Castor fiber) is the largest medium-sized amphibious mammal in the order Rodentia, belonging to the family Beaveridae and the genus Beaver. Beavers are fat and stout, with no obvious difference between males and females. They have short and blunt heads, small eyes, small ears and short necks. The incisors are sharp and the masseter muscles are particularly developed. It only takes 2 hours to bite off a 40 cm tree. The forelimbs are short and wide, without front webs, the hind limbs are strong and powerful, with full webs between the toes, and the tail is large and flat. The weight is 17-30kg, the body length is 60-100cm, and the tail length is 21-38cm; the newborn beaver baby is about 30-40cm in length and about 700g in weight. [0003] Beavers are nocturnal and seldom come out of their holes ...
