Abstract

PURPOSE:To reduce wave force of sea water by laying out sphere-shaped solid void structures which twist irregularly linear thermoplastic raw materials as sea blocks or artificial coral reefs. CONSTITUTION:Thermoplastic raw materials, such as molten polypropylene and polyethylene are inserted into an extruder. A linear thermoplastic raw material is extruded from the front of the extruder. The linear thermoplastic raw material is arranged to pass trough a liquid refrigerant. When the passing the raw material, adjoining linear thermoplastic raw materials are twisted irregularly on the basis of the application of their light specific weight. At the same time, they are welded with each other, thereby providing a sphere- shaped solid void structure 6. More specifically, they are laid out underwater with a rope 13 and an anchor 12. When sea water passes through the sphere shaped solid void structure 6, it is possible to reduce sea water energy with a surface friction force.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Device for integrally connecting and molding a spherical solid void structure and a method for manufacturing the same. The round shape illustrated in FIGS. 1 to 4 has a nozzle formed in a die of an extrusion molding machine. It is a sectional view showing the range. Since the thermoplastic molten raw material of polypropylene (PP) or polyethylene (PE) passes through the nozzle opened in the mold, the filament having a sectional shape is extruded downward, and the specific gravity is light when it comes into contact with the cooling water surface. The filaments curl laterally and the falling speed decreases, and irregular three-dimensional voids are formed on the surfaces of the other filaments adjacent to each other, and they contact each other and weld. In order to make it into a predetermined cylindrical shape, it passes through a round regular formwork (-3 in the figure) and is extruded into a cylindrical shape with irregular three-dimensional voids, then cooled in water and the cross-sectional shape of Figures 1 to 4 is shown. It is possible to form a cylindrical solid void structure having The three-dimensional void structure that is molded and extruded into a cylindrical shape is compressed and welded to the connection portion (-9 in the figure) by compressing and welding the linear portion with a compression stencil form (-4 in the figure) that regulates the shape of a sphere, and an elliptical cylinder. And a method for continuous production by integrally forming a spherical solid void structure (-6 in the figure) and the like. 1-1 Invention and Method of Forming the Center of the Sphere Figure 1 and Figure 2 show the range in which the nozzle is opened in a cross shape at the center of the sphere of the mold (-1 in the figure). After the wire is welded to form a three-dimensional space, the part becomes a hollow center hollow (-8 in the figure), and the three-dimensional space formed by the line is a central reinforcing part (-7 in the figure). The invention and its manufacturing method. Three-dimensional void structure of Jumonyu in the center of the circle (in the figure −
7) secures the amount of compression of the filament when the compression mold (-4 in the figure) compresses the cylindrical portion, along with the reinforcement of the structure. 1-2 Invention and method of compression molding of the connecting part The filaments are welded to form a three-dimensional void and are molded into a cylindrical shape,

(Fig.) Is formed into a spherical shape by compression, compression, and continuous molding, and the compression molded portion is used as a connection portion (-9 in the figure) with another adjacent spherical body,
A device and method for integrally molding (-11 in the figure). As for the form which is set to a spherical shape, two types of a compression form (-4 in the figure) and a receiving form (-5 in the figure) work together to set and form. The method of setting is to set the upper surface receiving part of the compression mold (-4 in the figure) from the bottom of the sphere to the center (Fig. 5). When the sea block (-6 in the figure) fills the upper surface receiving part, it is compressed. Frame (in the figure −
4) is released to the outside, and the sea block is shaped like a semi-circle at the bottom and flows downward (Fig. 6), and the receiving frame (in the figure-
5) is fixed in place to support the bottom of the seablock. The welded sea blocks are piled up to a predetermined height as they are, and a compression mold (-4 in the figure) compresses the sea blocks from the outside to weld the filaments to each other to set and shape the spherical sea blocks (Fig. 7). , Formwork is removed (8th
Figure) In the compression mold (-4 in the figure), the part where the filaments are welded becomes the connecting and connecting part (-9 in the figure) of another adjacent sphere, and there is unevenness in it, and the central recess is the cutting part ( (10) in the figure, and the convex part is a binding part (-9 in the figure) such as a rope at the time of three-dimensional molding. 1-3 Invention and Method of Cutting Section Molding The connection part of the spherical solid void structure is molded by compression with a compression mold. A device and a method for forming a V-shaped cut-in concave portion in the central portion, and forming the concave portion as a cut portion (10 in the drawing) for integral connection and a connecting portion (-9 in the drawing) for three-dimensional connection. 2 How to obtain the design criteria “Incoming wave force, when passing through a three-dimensional void structure, changes its waveform due to the consumption of energy due to the surface friction of the filaments and the flow velocity phase difference due to the collision with the void of the three-dimensional structure. Wave force can be reduced. ”We asked Tokyo Municipal Fisheries University, Department of Marine and Fisheries, Professor Mitsuru Nakamura to clarify the theory and verify this hydraulic property, and in February 1992,“ Permeability of three-dimensional void structure Report on characteristics and wave power "has been accepted. When the spherical solid void structure manufactured by the present invention is used as a wave-dissipating material, a contact oxidizer, etc. in a place where water flows, the transmittance,
Regarding the design criteria for obtaining the maximum wave force, etc., the contents, theoretical analysis, and formulas described in this report are occupied and can be used uniquely. 2-1 Waveform transmittance of the structure to be designed is calculated by the formula described in the design standard “report”, formula 21 and the maximum wave force to the structure is calculated by formula 25, which is illustrated below. 2-2 The similarity report “report” clarifies the design criteria from the basic characteristics of the three-dimensional void structure. When the shape of the wave-dissipating structure to be laid is deformed, a hydraulic model test is conducted for its hydraulic characteristics.
The local conversion value shall be calculated by the similarity rule. When converting the prototype using various values of the model, the similarity conversion formula 26 of the transmittance and the formula 28 of the maximum wave power are used to obtain the on-site converted value, and the following is an example. 3 How to use The idea of laying a spherical solid void structure in rivers, lakes and seawater for the purpose of using it as a wave-dissipating material, contact oxidizer, etc. and its method. )
Shall mainly be used as a wave-eliminating material for buffering incident wave force and as an oxidizing material for water purification that oxidatively decomposes organic matter in water from the lowest side of the food chain. The wire diameter of the spherical spherical sea block is about 2 mm to 4 mm, the cross section is uneven to increase the surface area, the porosity is about 95% to 96.5%, and the weight is adjusted according to the application. The standard per ball of the spherical sphere sea block is weight: 730 g (porosity: 97.
3%, surface area: about 57.0 m ² ) and weight: 870
The range is about g (porosity: 96.8%, surface area: 69 m ² ), but it should be adjusted in the manufacturing process depending on the intended use. The structural characteristics of the sea block are that the filaments are curled and welded to other filaments during molding.
