Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering, and in particular relates to a suspended circular fish reef belt structure and an assembly construction method. Background Art

[0002] At present, fish reefs are mainly made of concrete or other rigid materials. Due to the limitations of construction, transportation and deployment equipment, the size and weight of a single reef should not be too large. After being deployed, this type of reef mainly serves bottom fish and has limited effect on attracting middle and upper layer fish. If a single reef is superimposed in combination, it will face problems such as complex design, difficulty in combination, high production cost and limited scope of application.

[0003] In addition, traditional concrete fish reefs and riprap fish reefs of various shapes are made of materials that are not environmentally friendly and lack affinity. Fish and other aquatic organisms need to adapt before they can become their habitats. In muddy coastal areas, traditional fish reefs are heavy and mostly sink into the mud, leaving little reef for fish and other aquatic organisms to inhabit, eventually forming a "garbage dump" type of fish reef. Therefore, traditional fish reefs are not suitable for muddy coastal areas. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the present invention provides a suspended circular fish reef belt structure and an assembly construction method.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0043] A suspended annular fish reef belt structure comprises a multi-section pipe-shaped reef body 101, wherein the pipe-shaped reef body 101 is provided with a plurality of through holes 10101, and the ends of two adjacent pipe-shaped reef bodies 101 are spliced ​​by a joint pipe, wherein the joint pipe comprises a curved telescopic section, and both ends of the curved telescopic section are respectively provided with a splicing section for splicing with the corresponding end of the pipe-shaped reef body 101, and the multi-section pipe-shaped reef body 101 is spliced ​​by each joint pipe to form an annular fish reef belt 1, and the curved telescopic section of some joint pipes is divided into two curved telescopic sections, and a buoyancy block 10301 is provided between the two curved telescopic sections, and an anchor hook ring 4 is provided on the bottom surface of the buoyancy block 10301, and the anchor hook ring 4 is connected to an anchor 3 landed in the coastal zone mud through an anchor cable 2, and the anchor cable 2 and the anchor 3 make the annular fish reef belt 1 suspend above the coastal zone mud and form a suspended annular fish reef belt structure, see Fig.12 and Fig.13 .

[0044] The circular fish reef belt 1 can be suspended above the coastal mud by means of multiple buoyancy blocks 10301, multiple anchor cables 2 and anchors 3 to prevent the fish reefs from sinking into the mud and becoming incapable of functioning. In addition, for circular fish reef belts 1 of different sizes, since the buoyancy of the corresponding buoyancy blocks 10301 in the circular fish reef belts 1 of different sizes is different, it is only necessary to adjust the weight of the anchor 3 so that the anchor 3 provides the corresponding pulling force to the corresponding buoyancy block 10301 through the corresponding anchor cable 2, so that the circular fish reef belt 1 is always suspended in the water. For circular fish reef belts 1 of the same size, since the buoyancy of the corresponding buoyancy blocks 10301 in the circular fish reef belts 1 of the same size is the same, the pulling force provided by the anchor 3 to the corresponding buoyancy block 10301 through the corresponding anchor cable 2 is the same, and by adjusting the length of each anchor cable 2, the water depth in which the circular fish reef belt 1 is suspended can be adjusted, so that the circular fish reef belt 1 can provide a habitat for the middle and upper layer fish.

[0045] Among them, the through holes 10101 on each section of the tubular reef body 101 are interconnected. The through holes 10101 are not only channels for aquatic animals to enter and exit the tubular reef body 101, but also have a wave-breaking effect. The water flow and waves are not easy to overturn the annular fish reef belt 1, and it can adapt to wave impact. The overall structure of the annular fish reef belt 1 is stable, and the setting of the annular fish reef belt 1 reduces the waves in the enclosed waters.

[0046] Among them, the joint pipe with the buoyancy block 10301 is connected to the inner cavity of each section of the pipe-shaped reef body 101 in the circular fish reef belt 1.

[0047] Among them, the stiffness of the joint pipe is greater than the stiffness of the pipe-shaped reef body 101. The pipe-shaped reef body 101 is an elastic-plastic component. The circular fish reef belt 1 formed by splicing several sections of pipe-shaped reef bodies 101 can deform itself and approach a circular shape under the action of external force.

[0048] Among them, under the action of external force, the outer side of the curved expansion section in the joint pipe of the circular fish reef belt 1 is elongated while the inner side is compressed and shortened, and through its own contraction function, an arc connection is provided for the pipe-shaped reef bodies 101 on both sides.

[0049] The shorter the length of the pipe-shaped reef body 101 is, the closer the formed annular fish reef belt 1 is to a ring. Preferably, the length of the pipe-shaped reef body 101 is less than or equal to 2 m.

[0050] In one embodiment, the splicing section is inserted into the corresponding end of the pipe-shaped reef body 101, and the splicing section and the corresponding end of the pipe-shaped reef body 101 are fixedly connected by a pipe hoop 104 fixed to the outer side of the corresponding end of the pipe-shaped reef body 101, wherein the inner diameter of the pipe hoop 104 is adapted to the outer diameter of the pipe-shaped reef body 101, see Fig.11 Preferably, the pipe clamp 104 includes two semicircular buckles 10401, one end of the two buckles 10401 is hinged and the other end is locked by a locking member, see Fig.10 .

[0051] The materials of the joint pipe and the pipe clamp 104 are both plastic.

[0052] Among them, Figure 8 and Fig. 9 As shown, the outer diameter of the splicing section is equal to the inner diameter of the pipe-shaped reef body 101, the length of the splicing section is not less than 0.2m, the length of the joint pipe without the buoyancy block 10301 is not less than 0.5m, and the length of the joint pipe with the buoyancy block 10301 is greater than the length of the joint pipe without the buoyancy block 10301.

[0053] The width of the pipe clamp 104 is not less than 0.15 m.

[0054] In one embodiment, Figure 2-Figure 5 As shown, the tubular reef body 101 is made by curling a rectangular multi-layer bamboo board 10102, which is eco-friendly and environmentally friendly. The multi-layer bamboo board 10102 is provided with a plurality of through holes 10101, a tenon 10103 is provided at one edge of the multi-layer bamboo board 10102 and a groove 10104 is provided at the opposite edge of the other side, and the tenon 10103 is plugged into the groove 10104 and fixed by solid glue.

[0055] The multi-layer bamboo board 10102 is formed by stacking a plurality of rectangular single-layer bamboo boards 101021. Figure 1 , 2 As shown, the single-layer bamboo board 101021 is made of bamboo sheets, the width of the single-layer bamboo board 101021 is determined by the length of the single-section pipe-shaped reef body 101, and the length of the single-layer bamboo board 101021 is determined by the circumference of the single-section pipe-shaped reef body 101.

[0056] Among them, when the thickness of the multi-layer bamboo board 10102 is small, the two side edges of the groove 10104 are reinforced with strips to meet the strength of the multi-layer bamboo board 10102 at the groove 10104. Preferably, the width of the strips is twice the depth of the groove 10104.

[0057] Among them, the single-section pipe-shaped reef body 101 has no directionality, can be used universally, and is easy to assemble.

[0058] In the present invention, since the pipe-shaped reef body 101 is made of bamboo, which has the characteristics of biological affinity, rough surface and large specific surface area, the circular fish reef belt 1 formed has significant effects in resource conservation, environmental friendliness and low-carbon environmental protection, and can solve the problems of resource waste and environmental pollution caused by traditional materials. The comprehensive investment of the project is relatively economical, and the comprehensive economic and social benefits are better.

[0059] In one embodiment, some of the joint pipes are referred to as first joint pipes 102 and the remaining joint pipes are referred to as second joint pipes 103. Figure 6 and Figure 8 As shown, the first joint pipe 102 includes a first curved telescopic section 10201, and both ends of the first curved telescopic section 10201 are respectively provided with a first splicing section 10202 for splicing with the corresponding end of the pipe-shaped reef body 101. Figure 7 and Fig. 9 As shown, the second joint pipe 103 includes two sections of second curved telescopic segments 10302, one end of the two sections of second curved telescopic segments 10302 is connected to a buoyancy block 10301, and the other end of each section of the second curved telescopic segment 10302 is provided with a second splicing section 10303 for splicing with the corresponding end of the pipe-shaped reef body 101. The multiple sections of the pipe-shaped reef body 101 are spliced ​​through each first joint pipe 102 and each second joint pipe 103 to form a circular fish reef belt 1. The two sections of the first splicing sections 10202 in the first joint pipe 102 are symmetrically distributed on both sides of the first curved telescopic segment 10201; the two sections of the second splicing sections 10303 and the two sections of the second curved telescopic segments 10302 in the second joint pipe 103 are symmetrically distributed on both sides of the buoyancy block 10301, and the anchor hook ring 4 is arranged at the middle of the bottom surface of the buoyancy block 10301.

[0060] Preferably, the shape and size of each pipe-shaped reef body 101 are consistent, the size of each first joint pipe 102 is consistent, the size of each second joint pipe 103 is consistent, and a plurality of first joint pipes 102 of the same number are distributed between every two adjacent second joint pipes 103. The length of each anchor cable 2 is the same, and the anchor 3 is landed in the coastal mud directly below the circular fish reef belt 1.

[0061] When designing the circular fish reef belt 1, multiple second joint pipes 103 are symmetrically arranged according to the circumference of the circular fish reef belt 1, and then the length and number of the single-section pipe-shaped reef body 101 and the number of the first joint pipes 102 are determined according to the arc length between two adjacent second joint pipes 103.

[0062] The anchor 3 adopts a precast concrete block, and a plurality of anchor hooks 4 are symmetrically arranged on the upper part of a circle of the precast concrete block.

[0063] Among them, the anchor cable 2 is made of anti-corrosion material, generally nylon rope can be used, the length of the anchor cable 2 is determined according to the hovering height of the circular fish reef belt 1, the specifications and sizes of the anchor cables 2 set in the same circular fish reef belt 1 are the same, and can be universal, and hooks are set at both ends of each anchor cable 2, one end is hooked with the anchor cable hook ring 4 on the buoyancy block 10301, and the other end is hooked with the anchor cable hook ring 4 on the anchor 3, see Fig.12 and Fig.13 .

[0064] Among them, the buoyancy of the circular fish reef belt 1 is greater than the gravity, and the anchor cable 2 is tensioned to balance the buoyancy of the circular fish reef belt 1, and the weight of the anchor 3 is determined according to the tension required to be provided by the anchor cable 2. In order to stably anchor the anchor 3 in the coastal mud, specifically, the weight G of the anchor 3 needs to be greater than n×L×cosα, where n is the number of anchor cables 2, L is the tension of each anchor cable 2 on the anchor 3, and α is the angle between the anchor cable 2 and the vertical. Fig.15 ; and the length of the anchor cable 2 l = (R 2 +h 2 ) 1 / 2 =h / cosα, where R is the radius of the circular fish reef belt 1, and h is the hovering height; and the tension L of the anchor cable 2 on the buoyancy block 10301 = (FG 1 ) / cosα, where F is the buoyancy at the buoyancy block 10301, G 1 is the gravity at the buoyancy block 10301, see Fig.14 .

[0065] Among them, the buoyancy block 10301 can be made of foam board, which is a hollow cylinder with an inner circle and an outer square. The outer size of the cylinder is determined according to the required buoyancy. The inner diameter of the cylinder is adapted to the outer diameter of the second curved telescopic segment 10302. The two ends of the buoyancy block 10301 are respectively clamped at one end of the corresponding second curved telescopic segment 10302 and locked with a locking piece.

[0066] In one embodiment, each through hole 10101 on the pipe-shaped reef body 101 is circular and has the same size, and multiple through holes 10101 are evenly distributed on the corresponding pipe-shaped reef body 101, and the sum of the areas of the multiple through holes 10101 is greater than or equal to 1 / 3 of the outer surface area of ​​the pipe-shaped reef body 101 and less than or equal to 1 / 2 of the outer surface area of ​​the pipe-shaped reef body 101. In this way, the size of the through hole 10101 is small, while the size of the inner cavity of the pipe-shaped reef body 101 is large, which conforms to the living habits of aquatic animals and is suitable for aquatic animals to live.

[0067] The suspended annular fish reef belt structure of the present invention is also suitable for coastal zones with floating silt and deep water.

[0068] A coastal ecological field, comprising the above-mentioned suspended circular fish reef belt structure arranged in the coastal zone, wherein the inner side of the circular fish reef belt 1 in the suspended circular fish reef belt structure forms an inner ecological domain 5 and the outer side forms an outer ecological domain 6, Fig.16 Specifically, under the action of water flow, a relatively stable area or plankton activity range will be formed on the back of the circular fish reef belt 1, which is called the outer ecological domain 6, and the relatively stable water area constructed within the circular fish reef belt 1 is the inner ecological domain 5.

[0069] The circular fish reef belt 1 is used to enclose an area to form an ecological field, thereby achieving the purpose of managing the coastal zone in an area. Specifically, the use of a circular enclosure ring can not only connect the various sections of the pipeline-shaped reef body 101 into one, so that the circular fish reef belt 1 formed is reasonably stressed and more stable, but also can enclose an area of ​​water to form an ecological field, greatly increasing the effect of the fish reef.

[0070] This coastal ecological field is a circular ecological field with a larger inner edge ratio. Therefore, choosing the circular fish reef belt 1 to construct the ecological field is an effective way to optimize the allocation of limited resources and achieve efficient ecological protection.

[0071] Among them, an aquatic plant floating island is set up in the circular fish reef belt 1. The aquatic plant floating island does not need to be fixed by an anchor cable 2 and is in a floating state. Aquatic plants continue to grow in the circular fish reef belt 1, and aquatic animals reproduce and thrive in the circular fish reef belt 1. Various organisms are attracted to each other and continue to move in, forming a "closed" conservation. The interactions between organisms in the ecological field and between organisms and the environment jointly construct the marine ecosystem.

[0072] A coastal ecosystem, including a plurality of the above coastal ecological fields, see Fig.17 .

[0073] The coastal ecological field has important functions and roles in the coastal ecosystem, mainly including providing a place for organisms to survive and reproduce, maintaining the stability and diversity of the coastal ecosystem, and promoting material circulation and energy flow. It also has a buffering effect, which can reduce the interference of human activities on the ecosystem and protect biodiversity.

[0074] A method for assembling and constructing a suspended annular fish reef belt structure is provided, and is used for assembling and constructing the suspended annular fish reef belt structure, and comprises the following steps:

[0075] S1, making a multi-section pipe-shaped reef body 101, splicing the ends of two adjacent sections of the pipe-shaped reef body 101 through a joint pipe, splicing the multi-section pipe-shaped reef body 101 through each joint pipe to form a circular fish reef belt 1, and connecting each anchor cable hook ring 4 with the anchor 3 through the corresponding anchor cable 2;

[0076] S2, take at least 4 loops and arrange them symmetrically on the circular fish reef belt 1, the loop is a rope wound around the pipe-shaped reef body 101, and take a plurality of slings with the same number as the loops, preferably, the slings are nylon rope slings, take each loop as a hanging point, clamp one end of each sling with the corresponding hanging point, and fix the other end of each sling on the lifting ring;

[0077] S3. On the construction ship, the circular fish reef belt 1 is lifted by the lifting ring and placed in the designated waters of the coastal zone. The anchor 3 slowly sinks the circular fish reef belt 1 into the water. After the anchor 3 lands in the mud of the coastal zone, the suspended circular fish reef belt 1 is pulled by each anchor cable 2 to form a suspended circular fish reef belt structure. Then, each lifting cable is loosened, and the locking hooks of each lifting cable and the corresponding lifting points are automatically unlocked, and each lifting cable is lifted together by the lifting ring.

[0078] The lifting rings and slings are reusable and can be used again for lifting and installing other circular fish reef belts.

[0079] In the present invention, all components of the circular fish reef belt 1 are standardized and assembled, which is convenient for factory production and on-site construction, and can effectively shorten the construction period of the coastal ecological field.

[0080] In the present invention, the circular fish reef belt 1 can be assembled in a factory. If the diameter of the circular fish reef belt 1 is relatively large, it can be assembled in two halves and then transported to the site and spliced ​​on a construction ship.

[0081] In the present invention, the joint pipe with the buoyancy block 10301 is not only a joint of the annular fish reef belt 1, but also a hanging point during construction.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
