Description

[Detailed Description of the Invention] The present invention relates to a wave/tidal current control unit, and in particular,
This refers to a wave/tidal current control unit that is formed by combining multiple simple-shaped members, which itself has a relatively simple shape, and which controls and calms waves, tidal currents, etc. by combining multiple members. be.

The control and calming of waves, tides, water currents, etc. in the ocean, lakes, marshes, rivers, etc. have been developed for a long time in order to preserve shores, expand the use of water areas, and conserve water quality, and there are many naturally occurring ideas and improvements. There are inventions and ingenuity that are the result of human efforts.

For example, there are methods by stacking natural stones or concrete flocks called irregular wave-dissipating blocks, and a large-scale method called the caisson construction method. Hereinafter, existing construction methods other than the construction method according to the present invention will be referred to as conventional construction methods. However, these conventional construction methods have the disadvantages of increasing difficulty in obtaining materials (for example, the use of natural stone), wasting materials (concrete/flock), and prolonging the construction period on land (
In addition to the problems of long-term offshore work (natural stone, concrete blocks, caisson), and high costs, the current situation is not necessarily satisfactory from the perspective of landscape protection. .

Also, for example, if a wave-dissipating block, etc. is installed on a sloping water bottom, the offshore side of the water-dissipating block, etc. will be washed away by the water flow, and after long periods of use, the wave-dissipating block, etc. will fall to the offshore side. There is a problem with this.

The present invention solves the above-mentioned problems associated with conventional construction methods and provides a wave/tidal current control unit capable of controlling and calming waves, tidal currents, etc. In order to achieve this object, in the unit according to the present invention, each component of the unit can be manufactured on site such as on the coast, and at the same time, it can be manufactured in a factory,
The prefabricated components were transported to a predetermined assembly location via land or sea routes. The transported parts are assembled into a predetermined single unit at the nearest location, such as on a quay or a work barge, using trucks, heavy equipment such as cranes, and input equipment. The assembled single units are loaded onto a work boat such as a barge and towed to the target water area, and then placed one by one, in multiple rows, or in a staggered pattern on the water bottom by a work boat such as a hoist. This will form the ``wave/tidal current control works.'' EMBODIMENT OF THE INVENTION Hereinafter, one embodiment and a few application examples of the present invention will be described in detail based on the accompanying drawings. FIG. 1 shows an embodiment of a line of wave/tidal current control equipment consisting of a single control equipment unit 1 shown in FIGS. 2, 3, and 4.

The single unit shown in FIG. 2, FIG. 3, and FIG. The lower end of the rod-shaped land side diagonal village 7 is removably connected to the side, and the upper end of the offshore diagonal member 5 and the land side diagonal member 7 are removably connected. A scour prevention member 27 having a substantially rectangular cross section is pivotally attached to the offshore end of the base member 3, and a passageway is provided for deflecting and disturbing the water flow toward the offshore slope village 5 and the land side slope village 7. A number of water flow disturbance members 29 are provided.

The single unit 1 can stand on its own or stand on its own by assembling multiple units, and has sufficient stability and durability over many years with respect to movement and overturning against pressure or turbulence such as waves and currents. be.

As shown in FIGS. 5a, b, and c, the base member 3 is constructed by providing the two connecting members 9, 11 between the base parallel beams 3a, 3b, and the connecting members 9, 11 are Mortise holes 9a and 11a are provided so as to be gradually inclined toward the front and rear central portions of the base parallel beams 3a and 3b, respectively.

This base village 3 is stable by almost horizontal contact with the water bottom or the ground, and does not slide against waves or currents. As shown in FIGS. 6a, b, and c, the offshore diagonal member 5 has upper and lower ends of the offshore diagonal pillars 5a and 6b that are approximately equal to the mutual spacing between the base parallel beams 3a and 3b of the base member 3. The upper tenon 13 on the offshore side and the lower tenon 15 on the Y middle side are provided in the section.

The lower offshore tenon 15 is aligned with the mortise hole 9a of the base member 3 and fixed with a fastener 17 such as a bolt. As shown in FIGS. 7a, b, and c, the camp side diagonal member 7 includes land side diagonal pillars 7a, 7b having an interval approximately equal to the mutual spacing between the base parallel beams 3a, 3b of the base village 3.
A land side lower groove 19 is provided at the lower end of the land side inclined column 7a,
A tenon 21 is provided in the upper part between 7b.

The land side lower tenon 19 is inserted into the slot 11a of the base member and fixed by a fastening bolt 23 such as a bolt, and the tenon receiver 211 is inserted between the offshore side oblique pillars 5a and 5b.
The offshore upper tenon 13 of the offshore diagonal member 5 is received,
It is fixed by a fastening smell 25 like a bolt. Further, a scour prevention member 27 is provided at the offshore end of the base member 3, and a water flow disturbance member 29 is provided between the offshore inclined pillars 5a and 5b, between the land side inclined pillars 7a and 7b, and on the outside of these inclined pillars. It is provided.

The scour prevention member 27 has a generally acid-shaped cross section and is provided with a tenon 31, as shown in FIGS. 8a, b, and c.

The tenon 31 of this scour prevention part village 27 is connected to the base parallel beam 3.
It is inserted between a and 3b, and there is a bolt-like tightening odor 3
3, which is rotatably supported. Therefore, when it is installed on the water bottom, its elevation angle can be adjusted according to the undulations of the water bottom, and by bringing the pincer tip into contact with the water bottom, the water flow coming from the front will smoothly reach the top surface of the scour prevention member. It is something that is guided. Therefore, the water flow prevents the bottom of the water on the side of the basin from being scoured, and there is no fear that the unit will fall to the offshore side. As shown in FIGS. 9a, b, and c, the water stream lantern village 29 has a substantially trapezoidal longitudinal section (vertical section in the direction in which the water flow is received), and has a predetermined number of sections. It is installed for the purpose of increasing the efficiency of controlling and calming waves and currents by deflecting and disrupting water flow.

Although there are existing water flow disrupting members in the prior art, the water flow disrupting member of the present invention can disrupt water flow much more effectively than these conventional water flow disrupting members.

For example, in the example shown in Japanese Patent Publication No. 41-19868, the water flow disrupting member was in the shape of a horizontally long plate and was integrated in the horizontal direction, whereas in the present invention, the water flow disrupting member is provided in a unit. For example, as shown in FIG. 1, there are many gaps not only in the vertical direction but also in the horizontal direction between each water flow disturbance member. Therefore, when a water flow arrives from the front, the water flow flows into the large number of gaps and generates a far greater number of vortices behind the water flow disturbance member than in the conventional example. Therefore, according to the water flow lighting member of the present invention, waves, currents, etc. can be controlled and calmed very effectively. Note that the single unit is not necessarily limited to the above example, as long as it has sufficient functionality and durability for a sufficient number of years without causing any movement or overturning due to waves and currents. Figure 10, Figure 11, Figure 12
The figure shows other single unit examples.

FIG. 10 shows an example of a single unit having four members as basic components: a base member 41, an offshore diagonal member 42, a land diagonal member 43, and a scour prevention member. The offshore side diagonal member 42 and the land side diagonal member 43 have a plurality of protrusions 44 that have a water flow disturbance function, and if used in the opposite direction, 42 and 43 may have the same shape, and the main body There will be only two types of units and three villages. In this case, manufacturing, assembly, etc. are further facilitated. In addition, the land side oblique portion of the base member 41 is formed into a wedge shape to prevent the land side water bottom from being washed away. In order to prevent scouring of the water bottom on the land side, it is of course possible to provide a scouring prevention member 27 on the land side end of the base member 41, which is the same as the middle side. FIG. 11 is a single unit having a similar shape to FIG.

This single unit 5 has a slip prevention part 55 and a protrusion 54
is located on both sides of the offshore diagonal member 52 and the land diagonal member 53. The protrusion 54 is a single unit 5
They are provided with different phases so that the gap is relatively small when viewed from the front after being assembled in the shape of 0. Therefore, the effect of controlling waves and currents becomes even more remarkable. The single units shown in FIGS. 10 and 11 may be arranged side by side in a row as shown in FIG. 12, as in the arrangement row of single units shown in FIG. 2, as shown in FIG. , which are arranged in two or more rows or in a staggered pattern.

An example of assembly is shown next.

First, each component shown in FIGS.
To hang the silk stand as shown in the figure, use the mortise 9 in the base member.
Insert the middle lower tenon 15 of the offshore diagonal member 5 into the mortise hole 11a, and insert the lower land side tenon 19 of the land diagonal member 7 into the mortise hole 11a.
is inserted, the tenon 13 of the middle side diagonal member 5 is received by the groove receiver 21 of the land side diagonal village 7, and predetermined places are fastened with the fastening blades 17, 23, and 25.

Next, attach the tenon 31 of the scour prevention member 27 to the base parallel beam 3a.
, 3b, and is rotatably supported by a fastener 33. A predetermined number of the water flow lighting members 29 are fixed in advance to the offshore diagonal member 5 and the land diagonal member 7 with bolts, adhesive, etc. so as to exhibit a predetermined function. The single unit illustrated in Figs. 2 to 4 is transported to a designated water area, etc., and is sequentially installed on the bottom of the water using a work boat such as a hoist, a barge, or a tugboat. They will be installed in a staggered manner, creating an overall ``wave/tidal current control system.''

According to the structure described in the claims of this invention, the following effects can be obtained.

{11 Since it is an assembly type, it is extremely easy to manufacture, transport, and assemble.

Furthermore, unlike conventional methods, concrete is not poured and molded on site, but can be produced in a factory. Therefore, the construction period can be significantly shortened. Furthermore, it is also possible to combine a plurality of units in advance, fasten them together, and then transport them using a crane or the like and place them on the bottom of the water, thereby significantly shortening the construction equipment. [21] Since the scouring prevention member is provided, scouring of the bottom of the water on the offshore side by water current is prevented.

Therefore, the unit will not fall to the offshore side. This scour prevention member is also capable of closing the gap that occurs between the offshore end of the base member and the water bottom.

This gap causes the unit to be stirred up from below when strong waves arrive from offshore. Therefore, by closing the gap with the scour prevention member as described above, it is possible to prevent the unit from being stirred up from below by strong waves and, in some cases, from falling over. [3] Since a water turbulence member is provided for each unit, waves, currents, etc. can be controlled and calmed much more effectively than in the conventional example. Note that the configuration of this invention is not limited to the above-described embodiments, and may be implemented in modes other than the above-described embodiments, without changing the nature of this invention.
Of course, it can also be used as reinforcement for road maintenance, or for solving various other soil support problems.
