DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] Please refer to Figure 1 The shock-absorbing culvert with animal guiding and water draining functions comprises a square culvert, shock-absorbing structures 1 are arranged on the left and right sides and the upper side outside of the culvert, the shock-absorbing structures 1 are used to reduce the vibration caused by vehicle driving, reduce the noise in the culvert, and prevent animals from being frightened. A composite light-emitting coating structure 2 is arranged on the inside of the upper side of the culvert, which reduces the light difference in the daytime and plays the night light performance at night, thereby providing guidance for animal migration. Drainage structures 3 are arranged on the lower part of the two sides of the culvert, and an animal passage 4 is arranged at the middle part of the culvert. Outer extension plates 5 are arranged at the entrance and exit of the culvert. In arid and semi-arid areas, rainfall is less, but rainfall can easily cause geological disasters such as mountain torrents. The traditional culvert has a single function and is easily damaged by washing. The arrangement of the drainage structure can effectively protect the stability of the culvert.

The composite light-emitting coating structure 2 comprises a bottom adhesion layer 2-1, a bottom contrast layer 2-2, a middle light-emitting layer 2-3 and a surface protection layer 2-4 arranged in sequence. During construction, the steps are: ① brushing the bottom adhesion layer 2-1 on the top of the culvert and air-drying; ② spraying the white water-based bottom contrast layer 2-2 and air-drying; ③ brushing the middle light-emitting layer 2-3, which is composed of water-resistant rare earth strontium aluminate light-emitting material, water-soluble acrylic resin base material, talc powder, sericite powder and calcium carbonate powder filler and additives. The mass ratio of the selected light-emitting material to the water-soluble acrylic resin is 1:1, which is economical and meets the performance requirements of the light-emitting layer.
