Description

[Detailed description of the invention] This invention relates to a wave-dissipating levee used to weaken the force of waves and currents on coasts, ports, rivers, etc. The purpose is to have a large wave-dissipating effect and The purpose of the present invention is to provide a wave dissipating levee which is free from problems such as water spoilage due to water stagnation within the levee due to large water permeation, is inexpensive in material and construction cost, and is easy to manufacture and construct.

Conventionally, wave-dissipating levees have been put into practical use, such as rubble levees, irregular block levees, mixed levees, steel pipe type or steel sheet pile type wave-dissipating levees, but all of these have vertical walls at the top, so waves are not reflected. As a result, overlapping waves occur and the waves inside and outside the embankment become larger.

In addition, the permeability of rubble dykes is medium, that of mixed dykes is small, and that of steel pipes is zero, which causes problems such as water stagnation within the dyke and the water becoming rotten.

The present invention was made to solve the problems of conventional wave-dissipating banks, and involves gathering together multiple flexible wires, converging one end to form a stem, and leaving the other end free. This wave-dissipating levee is characterized by having a plurality of pseudo trees, each of which is expanded to form a tree crown, arranged in series or in parallel on a pedestal fixed underwater.

Hereinafter, the present invention will be explained with reference to the drawings.

Fig. 1 shows an embodiment of a pseudo tree A used in the present invention, in which a large number of flexible wire rods 1 are gathered together, one end of which is tied together and a stem a1, and the other end is free. It is made up of a tree crown part a2 which is expanded.

The lower end of the stem a□ is inserted into the pipe 2.

FIG. 2 shows a state in which the stem a1 and the pipe 2 are connected, and the stem a1 is filled and fixed in the pipe 2 with mortar 3 such as epoxy mortar.

The lower end of the stem a1 is curved outward to prevent it from coming out of the mortar 3 circles.

Numeral 4 is a rubber-based sealant that prevents the pseudo tree A from being swayed by water currents and waves, and its stem from rubbing against the upper end of the surrounding pipe 2 and being damaged.

Reference numeral 5 denotes a rod, which is inserted into the mortar 3 and tied at the top and bottom with iron wire or the like to prevent the stem □ from rotating or coming out of the mortar 3.

FIG. 3 shows another example of pseudo-tree A used in the present invention, in which the brown crown of the tree is developed to resemble a natural submarine tree.

Furthermore, as shown in Fig. 4, the pseudo tree A can have a structure in which the stem part a1 is raised to a certain extent, the wire rod 1 is spread out like a trumpet from its upper end, and its free end is hung down evenly, as shown in Fig. 5. As shown in FIG. 6, the stem a1 is made low so that the hanging free end of the wire rod 1 reaches the bottom surface of the water, and the wire rod 1 is branched into several bundles from the middle of the stem a1 as shown in FIG. It may also have a structure that is expanded.

The tree crown part a2 in the present invention is not limited to the above-mentioned embodiment, and may be any shape as long as the end part is expanded freely, and the free end part of the wire rod 1 is formed into a loop shape as shown in FIG. It's okay to be.

Alternatively, as shown in FIG. 8, for example, a plurality of pseudo trees A may be fitted into a plurality of branched pipes 2'.

These pseudo trees A are mounted in series or in parallel on a pedestal 6 fixedly installed in the water, as shown in FIG.

To attach the pseudo tree A to the pedestal 6, the pipe 2 provided on the stem of the pseudo tree A may be made of steel, and this may be directly welded to the pedestal 6, or it may be attached and detached using screws, etc. May be attached.

The pipe 2 may be a steel pipe or a plastic pipe made of vinyl chloride resin.

Figure 9 is an example in which a long pseudo-tree A is arranged, but the 10th
As shown in the figure, relatively short pseudo-trees A can be arranged in multiple stages.

In areas with strong waves, long pseudo trees are likely to be damaged, so it is advantageous to use short pseudo trees stacked in multiple tiers.

In addition, when a pseudo tree is damaged, a short pseudo tree is more advantageous in replacing it with a new one.

FIG. 11 is a plan view of FIG. 10, and the pseudo tree A is 3
They are arranged alternately in rows.

The type and thickness of the flexible wire, the shape of the pseudo trees, how they are arranged, etc. are appropriately designed and determined depending on the location of the wave-dissipating levee, the strength of waves, the required wave-dissipating effect, etc.

Examples of the flexible wire 1 include synthetic resin wire, piano wire,
Made of synthetic resin coated metal wire, fiber-reinforced plastic wire, or wire made of carbon fiber or inorganic fiber, diameter 0.1 to 10 mm, length 30C71 to 3 m
It can be used as a wire rod with a certain degree of strength, and its properties include high strength and hardness under compression, tension, bending, etc., as well as elastic recovery, and it can withstand long-term environmental conditions such as salt water, water temperature changes, and sunlight. It is preferable to use a material that can withstand (weather resistance) over a long period of time.

In particular, when polyester bristle yarn is used, seaweed and shellfish tend to adhere to it, and it also acts as an algae body.
preferable.

As described above, in the present invention, a wave-dissipating bank is created by arranging and installing pseudo trees in which the stems of flexible wires are bound together and the free ends of the waists are freely expanded, so that water currents and waves do not hit the wires. By going around to the rear, its momentum is effectively attenuated and its spread is prevented.

In addition, the amount of material used per space occupied by underwater space is small, and not only is the material cost low and construction is easy, but the tree canopy has a variety of shapes and sizes to suit the water flow, wave scale, and degree of suppression. Furthermore, since the gaps between the wires are complex and there are a combination of large and small spaces, water can easily pass through them, so there is no chance of water stagnation inside the breakwater and causing corrosion. effective.
