Description

Technical Field

[0001] The present invention relates to the technical field of artificial fish reefs, and particularly relates to an artificial fish reef structure based on waste concrete sleepers. Background Art

[0002] For a long time, the repair and construction transformation of railway lines have required the elimination of a large number of waste concrete sleepers. The waste sleepers are piled up for a long time, with great difficulty in collection, high safety risks, and limited recycling value, which have been long-standing problems. How to utilize waste sleepers is an urgent scientific problem to be solved. At present, the treatment of waste sleepers mainly adopts the traditional solid waste resource recycling method of crushing and then recycling, and its disadvantage is that the formed sleepers cannot be directly utilized, and the utilization efficiency needs to be improved.

[0003] China has good natural marine ecological environment conditions and rich aquatic biological resources. Artificial fish reefs are structures artificially placed in the ocean to improve the living environment of marine organisms and increase the number of marine organisms. Placing artificial fish reefs is the main focus of building marine pastures, developing the marine economy, and promoting the construction of a marine power. Traditional concrete artificial fish reefs have a large void volume, high transportation and placement costs, and need to be cast in multiple times during the manufacturing process, with great manufacturing difficulty. Summary of the Invention

[0004] The present invention provides an artificial fish reef structure based on waste concrete sleepers to solve the above technical problems.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

The present invention enables the waste concrete sleepers generated by railway lines to be reused through the setting of precast node members, not only generating new benefits, but also greatly reducing the manufacturing cost of artificial fish reefs.

[0007] Preferably, the thickness of the groove wall of the cast-in-situ groove is not less than 40 mm, and the groove depth is not less than 150 mm to ensure the structural strength.

[0008] Preferably, during the process of opening the cast-in-place groove on the concrete sleeper, the sleeper steel bars inside the concrete sleeper are avoided, and the U-shaped connecting bars provided on the concrete sleeper are welded to the sleeper steel bars.

[0009] Preferably, the U-shaped connecting bars are made of recycled glass fiber bars or basalt fiber composite bars for offshore wind turbine blades.

[0010] Preferably, the concrete used is UHPC or polymer concrete.

[0011] Preferably, the surface of the waste concrete sleeper is roughened to improve the bonding strength between the artificial reef and the seabed substrate or biofilm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the precast joint components provided in the present invention, the waste concrete sleepers generated by railway lines can be connected to each other by cast-in-place concrete to form artificial reefs for marine organisms to survive.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example 1

[0022] As Figure 1 shown, an artificial fish reef structure based on waste concrete sleepers includes waste concrete sleepers 1. The concrete sleepers 1 are interconnected by a plurality of precast joint members 2 to form a rectangular frame to form an artificial fish reef. By means of the provided precast joint members 2, the waste concrete sleepers 1 generated by railway lines can be interconnected to form an artificial fish reef for marine organisms to survive, which not only realizes the recycling of solid waste to generate new benefits, but also reduces the manufacturing cost of artificial fish reefs.

[0023] Specifically, as Figures 2-3 shown, the connecting ends of the above-mentioned precast joint members 2 and concrete sleepers 1 are both provided with cast-in-situ grooves 3. The groove walls of the cast-in-situ grooves 3 are provided with cast-in-situ holes 4, and U-shaped connecting bars 5 extending outside the cast-in-situ grooves 3 are arranged inside. As Figure 4 shown, the connecting ends of the concrete sleepers 1 and the precast joint members 2 are abutted against each other, so that the adjacent two U-shaped connecting bars 5 are staggered with each other to form a closed loop 6, and pins 7 are arranged on the closed loop 6 to ensure the connection strength between the precast joint members 2 and the concrete sleepers 1. Then, corrosion-resistant concrete is poured into the cast-in-situ grooves 3 through the cast-in-situ holes 4. After the concrete solidifies, the connection between the precast joint members 2 and the concrete sleepers 1 can be achieved.

[0024] As Figure 1 shown, the above-mentioned precast joint members 2 include two-way precast joint members, three-way precast joint members and four-way precast joint members. Among them, the two-way precast joint members have two connecting ends, which are respectively distributed at both ends of the line segment; the three-way precast joint members have three connecting ends, which are divided into models distributed at each end of the "T" shape and models distributed along the X, Y, and Z axes; the four-way precast joint members have four connecting ends, which are divided into models distributed at each end of the "cross" shape and models distributed along the X, Y, and Z axes respectively, and there are two connecting ends distributed on one of the axes.

[0025] During implementation, a plurality of concrete sleepers 1 are interconnected by the above-mentioned precast joint members 2 of each model by means of cast-in-situ concrete to form a rectangular frame. This rectangular frame is used as an artificial fish reef and is put into a predetermined sea area by a working ship. When the artificial fish reef sinks to the seabed, it forms an environment for marine organisms to survive.

[0026] As a preferred solution of the above embodiment, the wall thickness of the groove wall of the cast-in-situ groove 3 is not less than 40 mm, and the groove depth is not less than 150 mm.

[0027] As a preferred solution of the above embodiment, during the process of forming the cast-in-place groove 3 on the concrete sleeper 1, the sleeper steel bars 8 inside the concrete sleeper 1 are avoided, and the U-shaped connecting bars 5 provided on the concrete sleeper 1 are welded to the sleeper steel bars 8.

[0028] As a preferred solution of the above embodiment, the U-shaped connecting bars 5 are made of recycled glass fiber bars or basalt fiber composite bars for offshore wind turbine blades.

[0029] As a preferred solution of the above embodiment, the concrete used is UHPC or polymer concrete.

[0030] As a preferred solution of the above embodiment, the surface of the abandoned concrete sleeper 1 is roughened. The roughening design not only enhances the physical adhesion between the artificial fish reef and the marine environment, but also realizes the "structure-ecology" dual adhesion through ecological effects (such as biofilm formation and bait enrichment), ultimately increasing the fish catch and restoring the marine ecology. The rough surface also enhances water flow disturbance, reduces sediment deposition, and maintains long-term structural stability.

[0031] Certainly, the present invention can also have many other implementation manners. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
