DESCRIPTION HU500024 WIND-WAVE RESISTANT SEA FISHING PLATFORM BASED ON THREE-DIMENSIONAL ARRANGEMENT OF ARTIFICIAL REEFS AND

METHOD FOR CONSTRUCTING SAME

TECHNICAL FIELD The present application relates to construction engineering, and more particularly to a wind-wave resistant sea fishing platform based on three-dimensional arrangement of artificial reefs and a method for constructing the same.

BACKGROUND In China, the resources are seriously damaged owing to excessive offshore fishing. In this case, adjusting the fishery industry structure and developing recreational fishery have become inevitable measures for the sustainable use of marine biological resources. Recreational sea fishing is an important part of the recreational fishery, and due to the low technical requirements and easy popularization of the recreational sea fishing, the improvement of people’s living standards and the increase of the demand for participating in various field experience activities, the recreational fishery is now in a rapid development stage. In the northern coastal provinces such as Shandong and Liaoning, a floating platform is provided at an offshore area, which is mainly made by riveting of plastic floating blocks. These floating platforms are usually assembled and spliced on land and then transported to the sea area as a whole. These platforms are mainly used for environmental and biological monitoring of leisure sightseeing and marine ranching projects, and is secondarily used for fishing activities. In coastal waters of Jiangsu, Zhejiang and Fujian, monitoring platforms are arranged in marine ranches and mariculture areas, the functions of which are limited to the environmental and biological monitoring. In the southern provinces such as Guangdong, Guangxi and Hainan, due to the frequent occurrence of typhoon, the monitoring platform for marine ranches in sea areas is generally designed to be large in size. However, due to the high cost and single function, it is less feasible. Throughout the current domestic situation, there are no HU500024 actual cases of large-scale fishing platforms designed for fishing activities, and the only engineering facilities with auxiliary functions of sea fishing (such as docks, sea approach bridges and sightseeing platforms) and the scientific research monitoring platforms lack three-dimensional artificial maintenance facilities for the surface and bottom layers, which leads to limited resource conservation and maintenance of high output ecological functions, failing to withstand high-intensity sea fishing activities. On the other hand, in the existing sea fishing area, the wave suppression function of artificial floating components are not combined with the wave reduction functions of large sinking reefs, so that the sea fishing are extremely vulnerable to adverse sea conditions and cannot be carried out continuously. It can be seen that there is still a lack of unified design standards for sea fishing platforms in China, and the existing platforms are extremely vulnerable to sea conditions and fishing conditions. Therefore, it is urgent to develop new ideas in this field, introduce suitable facilities, and design a functional sea fishing platform with the goal of efficient use of water space. At present, at least several billions of funds per year are invested for the restoration of marine fishery resources, mainly for the enhancement and releasing of rivers and the construction of marine ranches. An important link in the construction of marine pastures is to provide various functional artificial reefs to achieve the alteration and restoration of habitats.

Generally, traditional sea fishing platforms are often disposed in a natural sea area with high density wild resource, however these areas have disadvantages of limited areas, fast resource consumption and slow recovery of fishing objects, and there is a lack of artificial blocking and wave elimination facilities around the platform and the seabed, making the platform extremely vulnerable to disasters such as typhoons. In view of this, the activities can be conducted only under good weather and sea conditions. At present, the northern marine leisure sightseeing platform is mainly made of floating plastic products, which have limited wind-wave resistance, while the marine monitoring platforms in the southern sea area are often designed with large scale and high cost, unsuitable for promotion. The main reasons why the above-mentioned technical problems cannot be effectively solved are as follows. 500024 (There is a lack of the practice associated with design and construction of a platform mainly for sea fishing.

(2) The platform with sea fishing as a subsidiary function fails to take the reality resource carrying capacity of the limited sea area into account. Traditional fishing platforms focus on resource utilization, and ignore the habitat modification and the conservation of fishing objects, resulting in unsustainable resource utilization.

(3) Traditional fishing platforms fail to combine the raft breeding with the wave reduction function of large anti-wave reefs, making them vulnerable to adverse sea conditions.

(4) The funds for resource restoration and marine ranching projects in China are mainly used for the artificial reef construction and the enhancement and releasing, ignoring the resource recapture such as fishing activities.

SUMMARY In view of the problems in the prior art, the present disclosure provides a wind-wave resistant sea fishing platform based on three-dimensional arrangement of artificial reefs and a method for constructing the same. In view of the above-mentioned practical requirement and technical limitations, the present disclosure introduces three-dimensional wave suppression and blocking facilities with artificial reefs as the main component on the basis of improving the original platform. At the same time, in view of the defect of poor sustainability in traditional sea fishing areas, floating facilities such as raft culture facilities and cage culture facilities are introduced to create a bait field, increase productivity in local waters and temporarily culture and domesticate the enhancement-releasing varieties. Through the optimized design of the three-dimensional habitat environment in the whole water layer, a habitat environment is provided for various marine organisms for feeding, avoiding predators and breeding, thereby constructing a high fish density and high diversity pattern with a large number of indigenous species, a large number of migratory species, and a continuous stay of released species, and ensuring the sustainability of platform fishing. In terms of the wind-wave resistant performance, the platform 500024 adopts a streamlined design, a frame-type hollow structure, a high-strength stainless steel support, and a concrete base to achieve extremely high stability after joining the pile surface. In case of a strong typhoon, the platform can be separated from the pile and hauled to a safe haven or land. In addition, the wave reduction functions of raft-type culture components and large sinking reefs are cleverly adopted, so that the surface water body exerts a ballast effect under the water resistance of a large number of floating components, while the large sinking reefs plays a ballast effect on the reciprocating flow, tidal current and vertical turbulence of the middle and lower water bodies, making the sea fishing platform effectively reduce the damage to the platform by wind waves and strong currents under typhoon weather.

DETAILED DESCRIPTION OF EMBODIMENTS In order to facilitate the understanding of the objects, features and advantages of the present disclosure, the disclosure will be described below in detail in conjunction with the accompanying drawings and embodiments.

The artificial reef is an artificial structure set up in specific waters to attract fish to live, feed, lay eggs or avoid predators, and further provide other creatures with a attachment habitat, so as to enable the protection and proliferation of marine biological resources.

The sea fishing platform is a small artificial facility fixed on the coastline or open sea, and used as an expansion site for sea fishing activities, which is designed to provide a comfortable and safe sea fishing environment for sea anglers.

The structure of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, the embodiment provides a wind-wave resistant sea fishing platform based on three-dimensional arrangement of artificial reefs, including: a main area 1 of the sea fishing platform, a cage culture area 2, a raft culture area 3, and a 500024 large sinking bottom reef area 4, an intertidal buffer area 5 and a supratidal land area

6.

The cage culture area 2 is respectively provided at a left corner and a right corner of a rear side of the main area of the sea fishing platform 1. The raft culture area 3 is provided at a left side, a right side and a front side of the main area 1 of the sea fishing platform. The large sinking reef area 4 is provided at a left side, a right side and a front side of the raft culture area 3. The intertidal buffer area 5 is provided behind the cage culture area, the raft culture area, and the large sinking reef area. The supratidal land area 6 is provided behind the intertidal buffer area.

The main area 1 of the sea fishing platform includes three parts: an approach bridge, a water platform, and an underwater pile. The approach bridge is connected to the intertidal buffer area and the supratidal land area in turn, and the water platform is engaged with the underwater piles.

The cage culture area 2 is composed of a cage main body (which can be enclosed), a sunken rock and an anchor chain. The sunken stone is placed in the cage main body; the anchor chain is bolted to the lower end of the cage main body.

The raft culture area 3 includes a floating ball, a water cable (or a bamboo frame), an underwater anchored fish reef, and a leap rope for connecting the fish reef and upper facilities. The floating ball is bolted to the underwater anchored reef through the water cable or the bamboo frame.

The present invention will be further described below in conjunction with the functions of each structure.

The functions of the main area 1 of the sea fishing platform of the present disclosure are as follows. Gravel reefs are placed into the main area to transform the sediment and prevent an erosion of the soft mud around the fish reefs and piles by the bottom flow, thereby avoiding a lack of function caused by the sinking and burying of the fish reefs. The frame reef is combined with the gravel reef to make the sediment completely changed into a hard-phase rock reef environment, thereby providing habitat, feeding and hiding places for the reef-loving and reef-trending fish, which can gather many types of fish to provide basic catches for sea fishing activities. 7500024 The functions of the cage culture area 2 are as follows. Cultivate the common local reef-trending fish. If the size of the fished species is too small, the fish can be put into the cage to continue stocking. The released species will be temporarily raised around the cage when the platform area is released. The special bait environment formed by breeding provides additional bait for the crustaceans and other creatures around the cages and the platform area, which increases the utilization rate of breeding bait, and further increases the density of shrimp and crab bait organisms around the platform, thereby providing basic bait for attracting large reef-promoting fish.

The functions of the raft culture area 3 are as follows. The raft structure itself also becomes a good shelter and bait ground for various fish juveniles, thereby providing additional catch protection for platform fishing activities. The raft culture area can become a middle and pelagic fish fishing ground in spring and summer, thereby expanding the fishing function of the platform.

The functions of the large sinking reef area 4 are as follows. Firstly, it serves as an underwater breakwater to buffer currents, eddies and turbulence, reduce the erosion of the bottom flow on the underwater part of the platform, and increase the stability and life of the platform. Secondly, these large reefs can induce fish on the outside, and the fish attracted by these reefs will further enter the sea fishing platform area due to differences in bait and water stability, which further guarantees the fishing base for sea fishing activities. In addition, due to the arrangement of large-scale reefs, the scouring effect of the bottom seawater on the three-anchored reefs of the raft culture area is reduced, and the safety of the breeding area is also increased.

The intertidal buffer area 5 can be completely exposed to the surface of the water at low tide during the high tide. The supratidal land area 6 cannot be covered by sea water.

As shown in FIG. 2, the embodiment provides a method for constructing a wind-wave resistant sea fishing platform based on the three-dimensional arrangement of artificial reefs, including the following steps.

S101: Site selection of platform 7500024 S102: Underwater piling of platform S103: Modification of sediment in core area of platform S104: Pouring in sea fishing platform S105: Construction of cage culture area S106: Construction of raft culture area S107: Construction of large reef area S108: Post-construction management and maintenance of platform function area The present disclosure will be further described below in conjunction with specific analysis.

S101: Site selection of platform The platform construction area is first needed to be assessed for the sea area right, and the site selection is carried out on the premise of conforming to the overall sea area planning. The construction area of this platform is suitable for the land area or the sea area near the shore of the island with a water depth of 10-20 m, where the minimum water depth is not less than 5 m. Both the open sea areas and the semi-enclosed sea areas are acceptable, but it is not suitable to select the platform site in areas such as inward bends with a poor water exchange.

Before constructing the platform, it is required to conduct surveys on sediment and topography of the selected area, where the area of the entire platform function area is preferably not less than 10 ha, otherwise the realization effect of the overall function is difficult to guarantee.

S102: Underwater piling of platform According to the columnar sampling results and the topographic scanning map, the piles are reasonably arranged in the main area of the sea fishing platform. The long axis of the pile surface formed by several piles is in a same direction as a main direction of a local tidal current. The total supporting capacity of all piles is not less than 150 t.

S103: Modification of sediment in core area of platform Firstly, 20-50 cm diameter engineering gravel reefs are placed in the main area of the sea fishing platform and the cage culture area at a density of 2-3 tons per square 500024 meter (the density can be adjusted according to the columnar sampling results, if the soft depositions are thicker, the delivery volume can be increased). The terrain is scanned one week after the placement is completed, and the placement status is confirmed. The supplementary placement is performed based on the scanned image. After the gravel reefs are placed, the frame-type hollow reefs (lengthxwidth>xheight=2 mx2 mx2 m) in the main area of the sea fishing platform are placed, where a frame reefs are placed at a distance of 2-5 m. The function of the gravel reef is mainly to modify the sediment and prevent the bottom flow from scouring the soft mud around the fish reef and piles, so as to avoid the loss of function caused by the sinking and burial of the fish reef. The frame reef is combined with the gravel reef to make the bottom of the platform completely changed into a hard-phase rock reef environment, thereby providing habitat, feeding and hiding places for the reef-loving and reef-trending fish, which can gather many types of fish to provide basic catches for sea fishing activities.

S104: Pouring of sea fishing water platform A fixed platform or a mobile platform is selected according to local sea conditions. After the split pouring is performed to obtain components of the mobile platform on land, the components are spliced and fixed by a large engineering ship. The fixed platform can be manufactured in the same pouring mode as the mobile platform according to the budget, or it can be manufactured at sea by stepwise. The thickness of the overall platform is not less than 0.5 m, and the total area is not less than 100 m°. The shape is comprehensively selected according to the sea environment, topography and design requirements. Various functional activity rooms can be added to the platform. In order to reduce the impact of wind and waves, an upper part of the platform is still designed with a frame-type hollow sampling to ensure permeability. The design of the canopy should fully refer to the local prevailing wind and a regular blowing route of typhoon.

S105: Construction of cage culture area The breeding cages are set in the cage culture area. The number and type are determined according to the area and water depth conditions. According to the density 500024 of 100” m/piece, the conventional cage is designed as a diameter of 8-10 m. If the water depth in the area is shallow, an overall enclosure can be constructed. The functions of the cage culture area are as follows. Cultivate common reef fishes in the local area. If the size of the fished species is too small, the fish can be put into the cage to continue stocking. When the platform area is released, the released species shall be raised temporarily around the cage. When releasing in the platform area, the released species temporarily raise around the cages. The special bait environment formed by breeding provides additional bait for the crustaceans and other creatures around the cages and the platform area, which increases the utilization rate of aquaculture bait, and also increases the density of shrimp and crab bait organisms around the platform, thereby providing basic bait to attract large reef fish.

S106: Construction of raft culture area A raft culture area is constructed around the main area of the sea fishing platform and the cage culture area. In order to make full use of the role of the fish reef, the floating raft components in this area no longer use pile driving, but are directly fixed on the anchor fish reef (the twisted I-shaped reef is adopted as a carrier and an anchor structure is respectively added at its four ends). One end of the steel cable is tied to the reef, and the other end is tied to a floating ball. The anchored reef is designed with a length, a width and a height all of 2 m, a diameter of 0.5 m, and an overall weight of about 5 ton. Under the action of the anchored fixed structure, it can prevent horizontal movement and vertical vibration, thereby ensuring the stability of the floating raft components. Anchored reefs are placed at a spacing of 5 m. After placement, the floating balls are connected vertically and horizontally at an average surface water depth of 1 m. The breeding rope can be used to cultivate shellfish and seaweed, or even the two can be cultivated simultaneously. The organic debris released by the breeding species in the breeding area is used to provide bait for the upper fish and benthic animals around the sea fishing platform. At the same time, the floating raft components itself also become a good shelter and bait ground for various fish juveniles, thereby providing additional catch protection for platform fishing activities.

The floating raft area can be used as a fishing ground for middle and pelagic fish in 500024 spring and summer, thereby expanding the fishing function of the platform. In addition, the floating raft mainly plays a role in the wave elimination. Since the space within 2 m of the surface water body is densely covered with various breeding components and breeding objects, which can achieve a ballast effect on the wind and waves in the area, thereby reducing the scouring damage caused by wind and waves to the sea fishing platform, and creating good conditions for normal fishing in the fishing area in windy weather (after passing the ballast of the floating raft, the sea around the sea fishing platform will be more stable than the outside). In order to ensure the good performance of the wave-eliminating effect of the floating raft, the radiation width of the breeding area is not less than 100 m.

S107: Construction of large reef areas Large artificial reefs with a characteristic height of not less than 3 m are placed in the large sinking reef area surrounding the raft culture area. The reefs in this area can use frame-type hollow reefs, but the permeability (permeability per unit area) of the reefs is reduced to less than 0.2. If conditions permit, accumulation reefs (small physical reefs with a length of about 1- 2 m) are adopted to construct the large fish reef area. The main functions of the fish reef in this area are as follows. Firstly, it serves as an underwater breakwater to buffer currents, eddies and turbulence, reduce the erosion of the underwater part of the platform by the bottom flow, and increase the stability and life of the platform. Moreover, these large reefs have an inducing effect on the fish on the outside, and the fish attracted by these reefs will further enter the sea fishing platform area due to the difference in bait and water stability, which further further guarantee the catch basis of sea fishing activities. In addition, due to the arrangement of large-scale reefs, the scouring effect of the bottom seawater on the anchored reefs in the raft culture area is reduced, and the safety of the breeding area is also increased.

S108: Post-construction management and maintenance of platform function area After completing the underwater project of the sea fishing platform, it will take several months to one year to manage and protect the sea fishing platform. Through the investigation and evaluation results inside and outside the platform, it is confirmed 7500024 that there are indeed higher resources around the platform before it can be opened for sea fishing activities.

FIG. 3 is an effect diagram of the wind-wave resistant sea fishing platform based on three-dimensional arrangement of artificial reefs according to an embodiment of the present disclosure. On the basis of the existing platform, three-dimensional wave suppression and blocking facilities with artificial reefs as a main component are introduced herein. At the same time, in view of the disadvantages of poor sustainability of traditional sea fishing grounds, raft culture and cage culture facilities are introduced to create a bait field for the temporary breeding and domestication of the releasing varieties, increasing the productivity in local waters and ensuring the sustainability of the platform fishing. In terms of the wind-wave resistant performance, the platform adopts a streamlined design, a frame-type hollow structure, a high-strength stainless steel support, and a concrete base to form a stable state after joining the pile surface. In case of a strong typhoon, the platform can be separated from the pile and hauled to a safe haven or land. Given the above, this platform is suitable for various near-shore sea areas.

Described above are only preferred embodiments of the present disclosure, which are not intended to limit the present disclosure. Any modifications, changes and replacements made by those skilled in the art without departing from the spirit of the disclosure shall fall within the scope of the disclosure defined by the appended claims.
