 Next, the assembling process, functions, and the like will be described.

These modules are used to extend natural land and create artificial land at sea. 1km square from the coast, 10k
It may be expanded to m square, 100 km square or the like. The larger the area, the greater the stability and the greater the value of use. Reaching the number of islands offshore and surrounding it further makes them less susceptible to wind waves and ocean currents.

First, the rock wall (4) to which the comb-shaped plates (7) and (8) are attached is laid in a required length.

Then, an artificial land module (17) on the opposite shore to which the comb plate (13) and the mooring plate (5) are attached is built at the factory, and transported to the vicinity of the comb plate (7) by a work boat. At that time, a bow-shaped float is placed under the mooring plate (5) to keep the mooring plate (5) horizontal and to reduce the resistance when towing the water. (Several modules may be connected and towed.) After the right edge of the retaining plate (5) is engaged with the comb-like plate (7), a number of short-cut shafts (11) are grooved one by one. 9) Put it inside, push it backward, and connect the mooring plate (5) and the comb plate (7).

Then, the module (18) is carried before the module (17), the right edge of the mooring plate (6) is engaged with the comb plate (8), and the shaft (12) is passed through the groove (10).

Then, open the hatch (21), enter the module (18), turn the waterproof bolt on the rear wall and screw it into the cap nut on the front wall of the module (17). ).

Next, the module (19) is carried to the side of (17), and the bolts in the module (17) are screwed into the cap nuts in (19) to connect them.

Next, the module (20) is carried, and the bolts in (18) are screwed into the nuts in (20), and the bolts in (20) are screwed into the nuts in (19) to join them.

Next, the wave protection module (25) is carried, the lower part is put under the module (19), and the two are connected with bolts (36).

Next, carry the breakwater module (26) and lower it (3
8) Bolt under the module (20).

 Thus, it is assembled in the state shown in the figure.

To insert a normal module to the left of module (20), loosen the bolts in (20), carry (26) offshore, and then carry a new regular module, and attach the right face to module (20). And the module (26) is connected to the left side.

When connecting a new shore module to the back of the module (17), first construct a rock wall with comb plates required for mooring, carry the new shore module, connect the mooring plate, and connect the module (17). ).

If a new module is connected, remove the bolts (23) on (17) and reattach the wavebreaker plate (22) to the edge of the new module, or attach a new wavebreaker plate.

Modules installed in this way can be used immediately, covering them with concrete or soil, laying roads, building buildings, building forests, and houses, warehouses, factories, You can build roads and other facilities. The interior will be used on the second and third floors as necessary. (The floor of each floor may be attached in advance. The top floor may have a side wall removed and a structure in which the upper wall is mounted on a number of columns.) Remove for repair or other reasons If necessary, the bolt can be loosened or the shaft (11) or (12) can be removed, for example.

However, if you want to connect the modules permanently and firmly, open a through hole in the wall and fix it with rivets, bolts and nuts, gas pressure welding, electric resistance welding, explosive bonding, etc. Is also good. Stealing may be performed using a thermal shock pressure welding device as shown in FIG.

In Fig. 4, (55) and (56) are steel plates. (57) and (58) are air tanks that also serve as the base for the left and right devices of the same structure. (59) (60)
Is the ventilation tube attached on top. (61) and (62) are electromagnetic vents inserted in the middle. (63) and (64) are cylinders attached to the upper end of the pipe. (65) and (66) are pistons. (67) (6
8) is a piston rod. (69) and (70) are hammers. (7
1) (72) is the gas burner nozzle.

First, a flame was applied to the steel plate (55) (5) from the nozzle (71) (72).
When the steel plate is glowed and heated, the electromagnetic vents (61) and (62) are opened, and the high-pressure air in the tanks (57) and (58) is sent into the cylinders (63) and (64), Press (65) and (66) against the steel plate and use a hammer (69)
(70) is impacted on the steel plate, and the steel plate is pressed.

The left and right devices are moved in parallel, and pressure welding is sequentially performed at other places to firmly connect the steel plates (59) and (60).

In this case, the steel plate is heated with a high-frequency coil provided near the hammers (69, 70), and after moving the coil, both hammers are hit on the steel plate, or the hammer is made of copper and the steel plate is pressed. In this state, energize, press-contact, or replace the hammer with an electromagnet that flows a strong low-frequency AC, sandwich the steel sheet with the attractive force of the magnetism of the left and right electromagnets, and generate a vortex in the steel sheet due to the change in magnetism, Heating,
They may be pressed against each other.

The water level of seawater (1) changes under the influence of tide, pressure, wind waves, and the like. If the module group is fixed to the rock wall (4), a large change in buoyancy is applied to the module group due to a change in water level, and a greater bending stress is generated at the connection with the rock wall according to the principle of leverage. Instantly the rock wall or module is destroyed.

However, since the hinge-shaped mooring device including the mooring plates (5) and (6) is used, the mooring plates (5) and (6) and the left and right combs are provided even when the module group moves up and down due to the water level change. The joint consisting of the plates (7), (8), (13) and (14) makes a rotational movement to deflect the force and only changes the inclination of the mooring plate.

The mooring plates (5) and (6) have the function of connecting the modules to the rock wall (4) and also have the function of smoothly connecting the natural land (3) and the artificial land. The surface of the road is paved with a hard rubber plate. You can add a lawn or a flower bed.

The module group receives the force of the horizontal component and the longitudinal component due to the wind wave and the tidal current, but the mooring plates (5) and (6) do not break even under the predicted maximum force.
Choose thickness, shape, structure and other designs. Several mooring devices similar to the mooring plates (5) and (6) may be additionally provided below them.

When the module group becomes larger than a certain size, the wave of the module group is hardly moved up and down, but when it is small, it is easily affected by the wave. However, even if the modules try to move up and down due to waves, the pistons (31) connected to the mooring plate cannot move freely due to the resistance of the seawater (34) (35) in the cylinder (30). Movement is also suppressed.

However, in the case of a long-period water level change such as a water level change due to the tide, the water is gradually moved through a gap between the piston rod and the piston and the cylinder.

If the wave going offshore to the shore is just above the top wall of the oxygenator (43), the bottom of the wave will enter the wave receiving cavity (46) and push the air there to the right, The air passes through the gap (47), the ventilation cavity (48), blows up from the small ventilation hole (44), is blown into the water of the crest passing over the upper wall (43), and the oxygen in the air dissolves in the water.

Most of the kinetic energy going to the right at the bottom of the wave is wasted as energy to push the air, weakening the impact of the wave. The upper part of the wave going right on the upper wall (43) passes under the wave receiving door (50) and hits the right wall of the cavity (52), but its impact is small.

On the way, the water in the fish tank (49) contains oxygen-rich water,
Useful for raising fish. When the waves go offshore, cavities (46) (48)
The water that enters is also drawn.

The big wave hits the door (50) at the top, pushes the door to the right and enters it, blowing out the air in the cavity (52) through the vent (28), consuming energy and hitting the right wall of the cavity (52) I hit it gently.

When the wave hits, the door (50) moves to the left and Ben (53) also moves to the left, allowing outside air to enter the cavity (52) through the vent (54).

Without the door (50), if a wave lower than the upper wall of the cavity (52) enters, the air in the cavity escapes to the left through the upper part of the crest and no collision action occurs.

In this way, the impact of the waves can be weakened, but if a wave that exceeds the wave protection module (26) comes in, the air compressor (39) is driven to take in the outside air through a pipe (not shown) and the cavity (40). ) And push up the wavebreak module (26) to prevent waves.

The fish tank (49) may be meshed with water to prevent the fish from escaping, or a door similar to the door (50) may be hung down from the left edge of the upper wall (43).

A net is hung from the periphery of the module group on the seabed, and the inside of the net is used as a fish tank, and the oxygen-rich water that enters the fish tank (49) is passed through the water pipe to be led into the fish tank. Good.

The small ventilation hole (44) may be provided in the upper part of the right wall (42) and at the boundary between the upper wall (43) and the guide wall (45) so as to face left and right.

The wind turbine generator may be turned by air blown out from the ventilation holes (27) and (28).

The floor without the above-mentioned side wall is provided at a position much higher than the waterline, but there is a risk of flooding if the waves are large, and it is necessary to prevent the flooding with a wavebreak module or the like.

The lower part (38) of the breakwater module may be extended to the left and the space created between modules (26) and (20) may be used for the port.

The above embodiment can be further modified in various ways. The outline is described below.

The sizes of the illustrated modules and mooring plates may be variously changed.

Drill holes of various diameters on each side wall of each module, attach a screw-type lid inside, connect the modules, remove the lid, and use it to pass human passages, water pipes, electric wires etc. It may be.

An artificial mountain with a height of about 100m may be built in a part of the module group.

There are various ways to make it, but while stacking the modules on the artificial land of the module group, attach the modules to the lower surface of the artificial land to create buoyancy equivalent to the weight piled on top, A special module with a mountain-like curved surface is attached to the outer surface, and soil is added to the outer surface, and trees are planted. (The interior can be used as a building.) The outer shape of the module is usually a rectangular parallelepiped, but for the exterior for artificial mountains and sand beaches as described above, the part in contact with other modules is a rectangular parallelepiped. What is necessary is just to make it a curved surface or an inclined surface obtained by arbitrarily shaving off a part of the rectangular parallelepiped.

When the left side of the rock wall (4) forms a curve when viewed from above, make the right side of the counter bank module parallel to it, arrange a number of mooring plates with a width of about 1 m and a width of about 10 m and align their ends with the curved lines , May be shifted.

In the event of a large earthquake, the natural land may suddenly shift and the mooring plate may be damaged. In order to avoid this, a mooring plate as shown in FIG. 5 may be used.

(73) in the figure shows a spring steel plate having a width of about 1 cm, a width of about 1 m, and a length of about 15 m, which is bent so as to form a sine waveform having a wavelength of about 10 cm when viewed from above. A large number of the plates are engaged with the comb-shaped plates (74) and (75) and passed through the shafts (76) and (77) to form a mooring device. (Adjacent plates (73) may be joined by diffusion welding or other means to form a honeycomb structure.) A thick hard rubber plate may be placed over this.

Partially insert an elastic plate in the middle of the rigid plate, or use a comb-like plate (15)
And the module (17) may be connected via a spring.

An elastic material may be inserted between the modules, a spring washer may be used for each waterproof bolt, etc., so that the entire module group has elasticity and cushioning, and absorbs sudden movements of a natural land.

It is desirable to use columns, beams, frames, and the like inside the modules as appropriate, as in ships and aircraft, to minimize the thickness of the exterior plate, and to reduce manufacturing costs.

It is desirable to provide each module with an inundation detector, a bottom surface that can protrude from a low surface and a periscope for monitoring underwater, an abnormality alarm, an automatic drainer, a strain detector, and the like.

In order to create a space of about 100 m square inside the module group, the walls of each module may be cut off as appropriate.
A module as shown in FIG. 7 may be used.

(78) in the figure is the lower wall. (79) is the upper wall. (80) is a side wall having a square window on each side. (81) is a rubber plate containing an adhesive with microcapsules that can be broken by heating the outer surface. (82) is a waterproof bolt attached to the side wall. (83) is a cap nut. (84) is a removable wall plate that covers each window on the side wall from the inside. (85) is a rubber plate inserted between it and the side wall plate. (86) is a bolt for attaching the wall plate (84) to the side wall (80).

If this module is floated on water, the rubber plate (85) will be packed, preventing water from entering inside. A large number of these modules are arranged in contact with a rubber plate (81) and connected with a waterproof bolt (82) and a cap nut (83) to form a module group.

The rubber plate (81) is heated by dielectric heating or the like, and the adjacent rubber plates are bonded together.

Next, loosen the bolt (86) and remove the wall plate (84) at an appropriate place to obtain a continuous space of any size.

A portion of the outer surface of the side wall (80) where the rubber plate (81) is not covered is projected outward to about half the thickness of the rubber plate (81),
When the bolt (82) is tightened, the metal side walls of the adjacent modules may come into contact with each other so that welding or the like can be easily exposed.

Note that two or more windows having wall plates attached to each wall may be provided. Depending on the application, a window may not be provided on one or two side walls.

In order to strengthen the coupling between the modules, make the left and right length of the odd-numbered counter-bank module counted from the front about 1.3 times that of the even-numbered module, so that all the odd-numbered and even-numbered modules are aligned with each other. In addition, attach an edge that protrudes the upper and lower walls by about 1 m from the upper and lower edges of the left and rear walls of each module, and attach recesses that mesh with the edges on the upper and lower walls near the upper and lower edges of the right and front walls. May be welded.

Part or all of each wall plate of the module is reinforced concrete, PS concrete, glass fiber reinforced concrete,
It may be made of a stone veneer obtained by bonding a number of stone plates with mortar, closed-cell pumice stone, or other materials.

When constructing an artificial land equivalent to the area of the Japanese archipelago, there is also a shortage of metal and cement.
What is necessary is just to process it into a wall board material with solar energy etc. and use it.

Modules made of these materials may be connected first with waterproof bolts, and mortar may be poured into a set space created between the outer wall surfaces to strengthen the connection.

In the Kanto region, when the Pacific Ocean plate sinks due to mantle convection, the edge of the Asian plate is pulled in, and when the Asian plate is restored, a large earthquake is said to occur, but a large amount of rock is mined at the contact surface of both plates Through the frictional area between the two, the total frictional force is reduced, and over a long period of time, many small earthquakes are caused, the Asian plate is restored, and the accumulated energy is released in a distributed manner Or rock mining, the Pacific Plate lacks the frictional force needed to pull the Asian Plate, deters seismic energy from accumulating, and removes deep underground rocks to reduce pressure and solidify at high pressure. It is also possible to turn the rocks into magmas, create artificial submarine volcanoes, convert the frictional energy of the two plates into thermal energy and release it.

In this case, it is necessary to disclose in detail the logical and experimental research on the mining position, shape (such as comb teeth), size, timing, mining equipment, and the like.

 The mined rock is used for artificial land.

When connecting a new module to a group of modules at sea,
Using a work boat with two long arms that can move freely, turn the electric bolt attached to the arm, fix one arm on the upper surface of the existing module and fix the other arm on the upper surface of the new module. Fix it to the cap nut, operate the arm to bring the new module into contact with the existing module, put a strong electromagnet in both modules, adhere the walls of both modules with the attractive force of both, and have a number of bolt tighteners It is desirable to mechanize the work by, for example, tightening a large number of waterproof bolts at once with a device. Repair of the bottom, submersibles for painting, etc. are also important.

In the above embodiment, the hinge type mooring device is used, but the following slide type mooring device may be used.

8 and 9, (87) is a rock wall. (88) is a steel channel embedded in the rock wall on the right, and T
It has a groove with a V-shaped cross section. (89) is the module for the opposite shore.
(90) is the same channel as (88) attached to the right side. (91) is H fitted to channels (88) and (90)
Shaped steel. (92) is a fall prevention plate extending leftward from the upper end. (93) is a thin connecting plate attached to the rock wall (87) on the right end and a steel plate on the module (89) on the left end. (94) is the sea surface. (95) is the sea floor.

After laying the module (89) against the rock wall (87), the H-shaped steel (91) is dropped from above the channels (88) and (90), and the fall prevention plate (92) is welded to the upper surface of the module.

When the sea surface (94) moves up and down, the H-shaped steel (91) slides in the channel (88), and the module (89) moves up and down without resistance. The altitude difference between the rock wall (87) and the upper surface of the module (89) fluctuates, but the connecting plate (93) bends at the thin portion at the right end, and the left end is always in contact with the upper surface of the module. , Can be easily moved onto the module from natural land. The H-section steel (91) has the function of strengthening the rock wall and the module horizontally.

Many T-shaped depressions are provided on all side walls of each module,
An H-beam may be used to strengthen the connection between the modules.

An oilless metal, a ball bearing, a roller bearing, or the like may be interposed between the channel (88) and the H-shaped steel material (91) to reduce the friction therebetween. A buffer may be inserted between the channel (90) and the module (89).

A large number of oxygen mixing devices including the wave receiving cavity (46) and the like may be provided in the sea around the module group so that the oxygen-rich seawater enters the fish farming area provided below the module group.

FIG. 10 shows an oxygen mixing device provided for such a purpose, and (96) is a main body. (97) is a float attached underneath. (98) and (99) are metal columns attached underneath.
(100) is a horizontal plate with almost the same area as the float (97) attached below. (101) and (102) are ropes. (103) is a concrete weight. (104) is the sea floor. (105) is the water surface.

When the wave hits the body (96) from the left, as described above, the lower part of the wave pressurizes the air in the body, causing bubbles to blow out from the upper surface near the left edge of the body and enter the water above the wave, causing oxygen Are mixed.

At that time, if the float (97) and the main body (98) rise according to the rising of the water surface due to the waves, the waves cannot enter the main body and the air inside cannot be blown into the water.

However, even if the float (97) receives the force of rising due to the waves, the water cannot be lifted as the water level rises because the horizontal plate (100) receives the resistance of water when it rises. Function is performed.

In addition, a column is set up on the weight (103), the above-mentioned cylinder (30) is fixed to the upper end thereof, and the upper end of the piston rod (32) is fixed to the float (97) so that the main body (96) does not move up and down with the wave. It may be.

A device adapted to a long-period water level change by a horizontal plate (100) or a cylinder (30) or the like, but capable of suppressing the vertical movement by a wave can be applied to a device utilizing wave power other than the present invention.

FIGS. 11 and 12 show a wave canceling module having a structure different from those of the above (25) and (26), and (106) is a float portion. (107)
(108) is a mounting plate connected to the left side. (109) is the upper and lower open space surrounded by them. (110) is 1m left and right
It has a honeycomb-like structure made of fluororesin or the like, which is a wave-dissipating plate of a small size and is difficult for organisms such as barnacles to adhere to. (11
1) is a large number of cavities provided in the plate (110), the top and bottom and front and rear widths thereof are about 20 cm, and the right end is narrowed and connected to a small hole (112) opened on the right side of the plate. (113) is the sea surface. (114) is the sea floor.

When the right side of the float (106) is attached to the edge of the module group, the offshore waves hit the small corrugated plate (110), enter the cavity (111), and the air inside the space (109) through the small holes (112). And the passing resistance at that time consumes the kinetic energy of the wave, resulting in a wave-eliminating effect.

 When the wave hits, the water that entered the cavity (111) also exits.

The longer the left and right sides of the air (111), the greater the wave-elimination effect, but the higher the production cost, so the selection is made according to the degree of the waves in the sea area.

The cavity (111) may have a slope of about 20 ° which rises to the right, or may be curved so as to rise to the right to make it easier for the water that has entered to flow out.

The cavity (111) is made into a uniform tunnel reaching the right end of the plate (110), and the right end is closed with a 21 × 21 cm square elastic metal sheet-made ben attached to the right surface of the plate (110), and the air in the cavity is closed. When is pushed to the right, the ben opens slightly, and after the air is formed, if the waves still push, the ben may open wide to allow water to escape to space (109).

In this case, the space (109) may be covered with a lid attached with wind power generation.

Create a fish farming space with a square-shaped module group surrounded by wavebreaker modules (25) and (26) with an oxygen mixing device shown in the first to third figures and moored on a rock wall or moored on the seabed with squids. Attach a cloth pool to the space, remove the door (50) and ben (53) of the breakwater module, open a number of small holes in the right wall of the cavity (52), and if the red tide pushes it there, Put a filter made of cloth, etc., go to the right on the upper wall (43), seawater mixed with oxygen and removing plankton is supplied to fish in the cloth pool, wastewater passes through the texture of the pool,
It may be allowed to escape into the lower seawater.

In this case, if the fish cultivation space is too large, a cloth pool is difficult to make, so a large number of fish cultivation tank modules as shown in FIGS.

In the figure, (115) is a piece of foam glass or other piece of several meters.
ロ -shaped float. (116) is a notch at the top. (117) is a cloth pool. (118) is a partial cutout.
(119) is a frame for attaching a cloth pool to the float. (120) is a mounting plate that extends at the top. (12
1) The upper part is a through plate of the frame (119), the closing plate to close the notch (116). (122) is a bolt holding the frame to the float. (123) is a through hole formed in the mounting plate. A large number of these modules are put in the fish farming space, and they are connected to each other with bolts and nuts passed through through holes (123), the closing plate (116) is pulled out, and the flow of seawater is cut out through the notches (116) and (118). to enable. (If the closing plate is a filter with a cloth attached to the frame, there is no need to pull it out. Cover the pool with a fish net to prevent fish from spilling.) Washing or replacing the cloth pool (117) In this case, the bolt (122) may be loosened and the frame (117) may be removed.

The pool (117) may be made of a plastic sheet, a metal plate, a metal mesh having a small mesh, or the like.

At this time, a number of small holes may be formed in the sheet, or a check vent having a vent hole for preventing fish from passing through the net may be attached to form a flow path of the wastewater.

A duct for guiding clean seawater to each pool may be provided on the frame (119).

It is practically economical to set the height of the mounting plate (120) at about 10 cm above the sea surface and the height of the breakwater module at about several tens of cm, but large waves can overcome them and the red tide plankton will be pooled ( 117) The pool may be covered with a cloth, plastic sheet, or other material to prevent this. The cover may be a pipe frame covered with cloth, a material that can be spread around a core, or a material fused on a cloth pool.

If the bubbles extruded from the small hole (112) are too large, oxygen will not easily dissolve into the water. To reduce the bubbles, the right side of the plate (110) on the right side of the small hole (112) and the upper wall A large number of small vents are opened and the luck without the left wall and the lower wall of about 20 × 20 × 5 cm in height × width × height is installed, and the air that has come out to the right from the small holes (112) is inside the box Into the water above the box through the small air holes as a number of small air bubbles.

The wave breaker plate (110) may be made of concrete, installed on the seabed, and used as a breakwater with an oxygen mixing device.

The guide plate (45) in the oxygen mixing device shown in FIGS. 2 and 3 guides the upper part of the wave hitting the left side of the device gently downward, and uses almost 100% of the total kinetic energy of the wave for pushing out air. The guide plate (45) and the upper wall (43) are hinged, and the guide plate (45) is
As in the case of (0), a pendulum-like motion may be made by a wave.

The lower wall (41) may be inclined downward to the left so that a wider range of wave energy can be used.

When the module is made of reinforced concrete, it is desirable to waterproof it by attaching a stainless steel plate or a plastic plate having a thickness of 1 mm or less to the outer surface or applying a waterproof paint. (If necessary, remove the waterproof layer.) When inserting a shock absorber against earthquakes at the connection between the rock wall and the mooring device or the connection between the mooring device and the module, connect the spring of the train connecting machine and the hydraulic cylinder in parallel. Although a shock absorber or the like described above may be used, only a metal spring or an air spring with a pneumatic control device that holds a piston in the middle of the cylinder may be inserted.

It is well known that a U-shaped breakwater that protrudes from the seabed to the sea surface and a floating artificial land is inserted in it, but in order to expand it, a new U-shaped breakwater is built outside of it. I have to. However, if the module of the present invention is connected around an existing breakwater, there is no need to newly install a breakwater.

In this case, the upper part of the artificial land inside and outside the breakwater may be connected by a bridge-like object or a box-like object.

The invention described in each claim of the claims is
If there is no similar prior invention, it may be slightly modified and used for other purposes.

By practicing the present invention as described above, it can be assembled relatively easily, in a short period of time, at low cost, and can be used in the original application from an early stage, and expansion work can always be easily performed. It is easy to have a large scale over time,
It is possible to obtain a floating artificial land module which has advantages such as easy breaking, application to a deep sea area, and easy removal.
