Embodiment 1

[0049] In this embodiment, the fish gate 2 is a continuous arched structure. The size of the fish door 2 can be calculated according to the water velocity, and the size should not be too large. The larger the size, the greater the flow force, and the greater the impact on the prefabricated concrete components of the ecological fish nest, and affect the structural strength of the fish nest. Simultaneously, the size of the fish door 2 should not be too small, which is unfavorable for slightly larger aquatic animals entering the box-type fish nest 1 to inhabit, reproduce or avoid natural enemies. The continuous arched fish gate 2 adopted in this embodiment not only has high strength, but also facilitates the adjustment of the size and the entry of aquatic animals.

Embodiment 2

[0051] In the present embodiment, aquatic plant connectors 5 are evenly distributed in the concrete box-shaped fish nest 1 , and superfine fiber artificial aquatic plants 4 are evenly distributed on the aquatic plant connectors 5 . The aquatic plant connector 5 can be set in different quantities according to the cavity size of the concrete box-shaped fish nest 1, and can be pre-embedded on the top of the wall or on the side wall of the wall, so as to facilitate the installation of superfine fiber artificial aquatic plants 4.

Embodiment 3

[0053] In this example, see Figure 4, The connector 3 includes a matching convex arc hinged connecting block 31 and a concave arc hinged connecting block 32, which are respectively arranged on both sides of the concrete box fish nest 1 along the length direction. These two hinged connections are in cylindrical contact, and cooperate with each other to form a relatively tight connection seam, which prevents the soil behind from leaking out of the connection, and has a good water and soil conservation function. The hinge joints protrude from the two ends of the concrete box-shaped fish nest 1, and the fish nest can be rotated forward and backward with the joint as the axis, so as to ensure the adaptability to river shorelines with different curvatures.

Abstract

The invention discloses a manufacture and construction process of a concrete-prefabricated artificial fish nest protection slope. The concrete-prefabricated artificial fish nest slope protection is formed by vertical and horizontal overlaying of a plurality of concrete box type fish nests. The bottom walls of the concrete box type fish nests are opened, the upper walls of the concrete box type fish nests are closed, the front walls facing to a river are provided with fish doors, the left and right side walls are provided with connecting pieces used for connecting the adjacent concrete box type fish nests, and superfine fiber artificial water plants are arranged in the concrete box type fish nests. The manufacture process comprises the manufacturing of the concrete-prefabricated artificial fish nests. The construction process comprises the assembly of the concrete-prefabricated artificial fish nests. Aquatic animals can go into internal hollow spaces of the concrete box type fish nests to perch and multiply through the fish doors, the superfine fiber artificial water plants can be used as attachments of animal breeding of the aquatic animals and attached base materials of microorganism breeding, and the construction of ecological protection slope can be carried out by taking the concrete box type fish nests as construction foundation to organically unify ecological environmental management and river bank protection management of the river.

Description

technical field [0001] The invention relates to a water conservancy construction component, in particular to a concrete prefabricated artificial fish nest slope protection and its manufacturing and construction technology. Background technique [0002] There is a very close relationship between the environment and aquatic animals. In order to protect aquatic animals and provide them with a safe habitat and breeding place, it is particularly important to protect the water environment and the diversity of aquatic organisms. At present, the common practice is to put stones and pebbles in the shallow water area of ​​the river bank to provide habitats for aquatic animals. However, this method cannot solve the stability of the river slope and prevent soil erosion. egg space. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a kind of concrete prefabricated artificial fish nest sl...
