Further, the length x width x height of the reef units is 0.9m x 0.3m x 0.1 m.
Furthermore, the composite ecological fish reef is formed by pouring ecological concrete containing fly ash at one time.
Furthermore, the number of the reef units is five, the lower layer is three adjacent reef units, and the upper layer is two adjacent reef units.
Furthermore, a plurality of circular holes are uniformly formed in the left side and the right side of each reef unit along the length direction, the number of the circular holes in the left side and the right side is equal, and the circular holes are horizontally aligned one by one.
Furthermore, the number of the round holes arranged on the reef unit is 12, and the left side and the right side of the reef unit are respectively 6.
Further, the aperture of the round hole is 5 cm.
Furthermore, a plurality of transplanting holes are uniformly arranged at the boundary groove between the reef units along the length direction, and aquatic plants are planted in the transplanting holes.
The invention has the beneficial effects that:
1. the ecological fish reef is a multilayer structure which is narrow at the top and wide at the bottom and is formed by a plurality of semicircular tile-shaped reef body units, can be stably placed in a river channel, has large surface area, forms a transparent sheltering cavity in the inner space, and can provide a place for fish inhabiting and breeding.
2. The contact area between the bottom of the ecological fish reef and the river bottom is small, and the problem that the traditional ecological fish reef blocks the ecological chain of the water-soil interface of the river bottom is effectively solved.
3. The ecological fish reef has the advantages of simple structure, small volume, light weight, low cost and convenient transportation and installation. Simultaneously, the ecological fish shelter can make according to the actual conditions in river course and put in, is applicable to small-size city river course.

Detailed Description
The composite ecological fish reef suitable for the urban river according to the present invention will be described in detail with reference to the accompanying drawings and specific examples.
As shown in fig. 1 to 3, a compound ecological fish reef suitable for urban river course, for the multilayer structure of narrow top and wide bottom that comprises a plurality of reef body units 1, reef body unit 1 is half circular tile structure, and the reef body unit 1 long limit of the same floor leans on, and the reef body unit 1 of upper and lower floor staggers half position between, constitutes a plurality of communicating sheltering chamber around in the compound ecological fish reef, and the inner space is penetrating, has improved the utilization ratio of space, provides the place for fish gathering, perching, breed.
In the embodiment, the composite ecological fish reef is formed by pouring ecological concrete containing fly ash at one time, and is easy to process. The ecological concrete has the advantages of high porosity and good water permeability, and is beneficial to the attached growth of aquatic animals, plants and microorganisms. Meanwhile, the ecological concrete is rough and scouring-resistant, so that the friction force on the surface of the reef body can be improved, and the adhesion of fish eggs is facilitated, and the survival rate of the fish eggs is improved.
The number of the reef units 1 is five, the lower layer is three adjacent reef units 1, the upper layer is two adjacent reef units 1, the reef units can be stably arranged in a river channel, the contact area of the bottom of the ecological fish reef and the river bottom is small, and the problem that the traditional ecological fish reef blocks the water-soil interface ecological chain of the river bottom is effectively solved. The length multiplied by the width multiplied by the height multiplied by the reef body unit 1 is 0.9m multiplied by 0.3m multiplied by 0.1m, the volume is small, the weight is light, and the transportation cost is low.
In addition, a plurality of circular holes 2 have evenly been seted up along length direction in the left and right sides of each reef body unit 1, and the side circular hole 2 quantity of controlling equals, and level alignment one by one is favorable to rivers like this at the inside flow of fish shelter, reduces the influence that the fish shelter was flooded to the river course. In this embodiment, the reef unit 1 has 12 circular holes 2, 6 holes on the left and right sides. The aperture of the round hole 2 is 5 cm. The round holes 2 are used for improving the permeability inside and outside the fish reef, are beneficial to the exchange of water bodies, reduce the resistance borne by the reef and provide channels for the fish to swim, avoid the enemy and enter and exit. In addition, the circular holes 2 on the reef body unit 1 also save materials and reduce the production cost.
A plurality of transplanting holes 3 are uniformly arranged at the boundary groove between the reef units 1 along the length direction, and aquatic plants 4 are planted in the transplanting holes 3. The groove structure is beneficial to accumulation of soil and organic matters, and is beneficial to improving the survival rate of the aquatic plants 4. The transplanted aquatic plant 4 can improve water quality and provide a better living environment for fish.
The tile structure composite ecological fish reef can be expanded in structure and quantity according to requirements. As shown in fig. 4, the ecological fish reef is thrown into a small urban river channel with the average water depth of 2 meters at intervals from left to right, the size of the fish reef is 0.9m multiplied by 0.2m, the throwing area proportion of the ecological fish reef is about 15%, the scheme can improve the number of fish schools in the area, recover the coverage area of aquatic plants, remarkably improve the water quality and maintain the balance of a good ecological system.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any alternative or alternative method that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention.
