Problems solved by technology

[0003] The purpose of this invention is to provide a method for assembling large-scale nets and nets between two coasts, to effectively solve the problem of the assembly method of large-scale nets and nets between two complex terrain coasts, to effectively shorten the length of large-scale nets and nets. The assembly time between the two coasts can effectively prevent the escape of cultured fish between the coast and the large-scale nets, improve the impact resistance of large-scale nets, improve the overall efficiency of large-scale breeding seines or marine ranches, and boost large-scale farming Sustainable and healthy development of seine or sea pasture farming

Embodiment 1

[0007]Embodiment 1: the specific implementation mode of the present invention (referring to accompanying drawing) adopts the large-scale net gear net clothing 7 of float class 8, lower class 14, left and right edge classes, copper alloy braided net 17, reinforced concrete column and square reinforced concrete Pile 19, a vertical force line 18 is installed every 1.84m between the left edge line 6 and the right edge line of the large-scale net clothes; the reinforced concrete column is installed with a ring every 10cm (about 10cm) perpendicular to the axis line of the column Polyester rope buckle 5, penetrate a hanging net vertical force line 3 in the ring-shaped polyester rope buckle and tie it up and fix it; drive the lower end of the first reinforced concrete column 9 into the seabed at the intersection of the left coast 1 and the large-scale netting 2.5m, and ensure that the vertical force line of the hanging net on the first reinforced concrete column is located on the side ...

Embodiment 2

[0008] Embodiment 2: According to the method described in Example 1, except that the large-scale nets and nets are equipped in a conventional manner, the preferred large-scale nets and nets are "UHMWPE-178tex × 37-50" ultra-high molecular weight polyethylene warp knitting Net, that is, the ultra-high molecular weight polyethylene fiber yarn with a linear density of 178tex is warped into an ultra-high molecular weight polyethylene fiber yarn with a linear density of 178tex, and then according to the mesh size of 50mm, "7 loops + 16 weft inserts" 23 ultra-high molecular weight polyethylene fiber yarns with a linear density of 178tex are processed by warp knitting machines into ultra-high molecular weight polyethylene warp knitting with a specification of "UHMWPE-178tex×37-50". net, and then use antifouling agent for fishing nets to carry out antifouling treatment on the ultra-high molecular weight polyethylene warp-knitted net, and obtain an anti-fouling ultra-high molecular weig...

Abstract

A method of fitting large fishing tackle net between two shores is characterized in that a reinforced concrete column is driven to 2.5m of the sea bed at an intersection of large fishing tackle net and each of left and right shores, a reinforced concrete dyke is cast between the reinforced concrete column and each of the left and right shores, a reinforced concrete horizontal net weir is cast between the two reinforced concrete dykes, a hanger horizontal lacing line is fixed on the top of the reinforced concrete horizontal net weir, a left side line of the large fishing tackle net is fixedly tied and connected to a hanger vertical lacing line on the left reinforced concrete column, a lower line of the large fishing tackle net is fixedly tied and connected to the hanger horizontal lacing line, a right side line of the large fishing tackle is fixedly tied and connected to a hanger vertical lacing line on the right reinforced concrete column, and finally, the ends of float lines of the large fishing tackle net are fixedly tied and connected to the left and right reinforced concrete columns.

Description

technical field [0001] The invention belongs to the technical field of large-scale aquaculture seine or marine pasture dam engineering, and in particular relates to an assembly method of large-scale nets and net clothes between two coasts. Background technique [0002] In the technical field of large-scale breeding seine or marine ranch dam engineering, it will involve the assembly method of large-scale net gear and net clothing between two complex terrain coasts. If the problem of the assembly method of large-scale nets and nets between the two coasts cannot be effectively solved, large-scale nets and nets will not be able to resist the long-term impact of waves and currents, and the short-term impact of storm surges in typhoon weather, and will not be able to prevent the coast from colliding with the coast. Fish escape accidents occurred in the large-scale netting room, and people cannot normally carry out large-scale breeding seines or fish farming in marine pastures. Be...
