Description

  In the present invention, water shortage is solved and disaster prevention is performed by a dike having a water storage function that does not break down due to landslides. Normally, river drainage water and groundwater drainage under the embankment that causes liquefaction is stored, and drinking water, industrial water, and agricultural water are filled with river filtered water during flooding and effective during the dry season and drought. Use. On the “earthquake-resistant storage embankment”, which functions to prevent torrents by the weight of water and facilities on the earthquake-resistant foundation

Conventional embankments are ordinary civil engineering that digs the riverbed, lays piles on the riverbank, fills the embankment mainly for revetment work, raises the embankment by tightening the road surface, and reinforces the surface of the river surface with concrete walls and blocks stacked to create a bank The technology to form a dike by work was completed.
However, this bank method requires a large amount of earth and sand, and if it overflows due to rainfall exceeding common sense, it absorbs water at the exposed part of the backside of the bank and the entire bank is saturated with water, It often broke down as fluid mud and collapsed.
Therefore, in recent years, the bank surface coating technology for reinforcing concrete walls and blocks on the inland side opposite the river surface has been expanded.
However, as global warming progresses, local precipitation changes have become intense, and disasters of a scale that cannot be considered by conventional common sense have occurred frequently.
In other words, if the flood continues for a long time due to a heavy flood, there are cases where the walls break down due to flooding even if concrete walls and blocks are piled up behind the embankment.

  Due to global warming, a vast area has been submerged and severely damaged by storms and floods overseas, but there are many disasters that can be prevented if the levee is high enough for several meters of reinforced concrete that does not collapse. .

  On the coast, sea level rises due to global warming, the land is eroded year by year, and the number of places where people can live is rapidly decreasing, and there is almost no way to do it in underdeveloped countries. In this case as well, it is important to install a dike around the coast and raise the land where water can be stored.

While global warming causes disasters due to heavy rains, it can also cause drought damage due to long-term sunshine. In the future world, it is important how to secure clean fresh water, and it is becoming difficult to secure clean water, industrial water, agricultural water, etc. in big cities, causing serious problems.
Current irrigation is often provided by water from rivers, swamps, water from mountainous dams such as multipurpose dams and irrigation dams, and is often converted to drinking water at water treatment plants.
The water of the dam is difficult to say that clean water is secured because there are bad conditions such as sediment accumulation due to mountain collapse, decay of bottom sediment due to water stagnation, and the occurrence of blue water.
In addition, the water sources of big cities are many dam lakes and dirty lakes where blue sea bream occurs, often producing bad odors and removing bad odors by ozone treatment and purifying them and using them for drinking water. Currently.

Patent document 1 is going to utilize a water tank as a bank. Proposing a continuous concrete aquarium installed on the riverbank is basically the same idea as the present invention, but Patent Document 1 has a simple structure and is supposed to cope with breakage of a dike. There is no specific content, which is very different from the present invention. In other words, in addition to the dynamic destructive force of the water flow, complex impacts such as driftwood and debris flow are applied to the torrent during flooding, and a force to push out from the inside of the dike is necessary to strengthen the dike. Patent document 1 is only a proposal as a water storage tank.
In detail, patent document 1 is a structure waterproofed only with a concrete outer wall, and does not consider about the failure | damage of an outer wall. In the idea of the present invention, the dam is pressed by the water pressure and the weight of the water stored in the high levee, the inner pressure that pushes the outer wall of the dyke works from the inside of the levee, and the outer wall has a structure that reduces the dynamic impact due to flooding. . Moreover, the barrier multiple structure of the present invention works in conjunction with the internal partition. Even if a part of the outer wall is damaged, the present invention and Patent Document 1 are different because the second and third barriers are provided by the inner barrier. Further, the water sampling of Patent Document 1 is a method of collecting and storing river water as it is, but in the present invention, the river bottom and riverbed are regarded as a huge filtration layer, and river groundwater and fresh water under the levee are collected. Since it is a method of collecting water, it is basically different.

Patent Literature 2, Patent Literature 3, Patent Literature 4, and Patent Literature 5 are related patents by the same applicant, and the portion of Patent Literature 2 includes a part with a built-in reservoir that overlaps with Patent Literature 1. The structure itself is a culvert structure that allows river water to flow inside, and is mainly built on the river. The embankment function is a part of concrete barrier that allows internal river water to pass through, and the structure is an artificial river structure that allows the river to pass through the inside of the structure as a culvert.
Therefore, structurally, like the present invention, it is a structure that is partitioned by a support column and a partition wall, but does not focus on the water storage function. It differs from the mass storage function and disaster prevention of the present invention. In addition, water sampling during storage. By collecting the river water as it is and storing it, the river bottom and riverbed of the present invention are regarded as a huge filtration layer, and groundwater is collected from the groundwater of the river and underground water under the dike to prevent liquefaction of the ground. It is different from the intention of this patent aiming at an earthquake-resistant structure.

  Patent document 6 is a water tank provided along a dike on a normal earth and sand dike. A river water storage facility also serving as a dike is characterized in that the water intake provided in the water storage tank exists at a position where water can be taken when the water level of the river rises above a certain level. It is not a seismic structure water storage dike aiming to strengthen the dike function by securing the weight of the whole dike with the weight of water as shown in the present invention.

As a recent invention, there is a construction method of a water storage structure on a sand and sand bank shown in Patent Document 7.
This is a construction method of a water storage structure on a soil embankment shown in Patent Document 7. The purpose is to increase the height of the levee body without lengthening it and to excavate the upper part of the dam body in order to counter the rise of the flood water level, and to provide a first protective member with tensile strength characteristics. Both sides of the bank are sandwiched between protective members, and measures are taken to prevent the bank from being damaged by water. It is a method of installing a water storage structure at the top, but it is not a dike structure with the entire bank as a water storage tank.

Most of the dykes are on soft ground, and the liquefaction of the ground caused by an earthquake destroys the function of the dyke from the ground up. There are over 200 patent documents related to the prevention of ground liquefaction. The contents are many technologies for earthquake countermeasures with the main purpose of strengthening residential land, building construction, and factory ground.
As for the technical contents, many technologies have been proposed, such as the installation of impermeable walls by impermeable walls, the ground reinforcement technology by placing concrete piles, the ground reinforcement by installation of lattice frames, and forced drainage by drain burial.

  In Patent Document 8, when constructing a waterproof levee, the joint portion of the impermeable wall sheet pile is waterproofed, inserted continuously, and a waterproof material is deeply branched by pressure between the waterproof wall and the waterproof dam. This is a technology that stabilizes the embankment dam on soft ground. In the seismic structure of the present invention, the impervious wall is installed by digging a groove with a trencher or backhoe after driving a sheet pile, forming an impermeable wall into the groove, and forcibly draining by ground reinforcement technology by concrete pile driving and drain burial. Since the liquefaction prevention is achieved by a combined technique with water sampling, it differs from Patent Document 8.

  In patent document 9, it is a liquefaction prevention method that does not form a waterway under the embankment structure for the purpose of fluid storage or water shielding such as river dikes, reservoirs, oil breakwaters, etc. This is a technique for preventing liquefaction by providing underground walls on the inside and outside of the dike, arranging earth anchors obliquely downward toward the lower part of the embankment structure, and connecting the continuous underground walls and earth anchors. In the prevention of liquefaction according to the present invention, an earth anchor is not used, and the protective wall is not a steel sheet pile but a concrete waterproof wall, which is different from Patent Document 9.

  In Patent Document 10, the surroundings of a structure are surrounded by a dead wall to a soil layer that does not liquefy, the internal foundation pile is driven to a support ground that does not liquefy, the structure is installed on the foundation pile, and a solidified material is used. This technology integrates piles and structures. In the present invention, a waterproof wall is installed up to the base layer, the foundation pile is driven to the support ground that does not liquefy, and the pile is fixed between the upper part of the foundation pile with solid concrete, but it is liquefied by underground culvert. A structure that collects water contained in the soil layer to be used as irrigation water and a panel surrounded by cushion rubber according to the interval between the foundation piles are spread, and a rubber cushion is placed on the top to equalize the weight on each foundation pile The structure is different from that of Patent Document 10.

Patent Document 11 shows a liquefaction prevention method related to underdrainage. The contents are intended to prevent liquefaction under the embankment embankment, including bulkhead installation, drain installation and forced drainage along the embankment.
Patent document 11 is a normal embankment embankment, and is a system in which underdrainage is also sent deep underground. In the present invention, the river soil layer is utilized as a huge filtration device from the riverbed underground and under the dike, and the groundwater in the soil layer under the dike is collected as clean water. Since it also serves as water, it is basically different from the content of Patent Document 11.

  Patent Literature 12 proposes a recent ground liquefaction prevention method. The present invention is a technique for preventing fluidization of a structure built on a liquefied ground by forming a grid-like ground improvement wall structure. This is different from the technology for preventing fluidization by mutual support of concrete panels surrounded by cushion rubber connected to the foundation pile of the present invention.

  The reservoir dike stores water for a long period of time, so it is easy for scale and water to decay. In addition, at the stage of use for irrigation, the nature of water has a great influence on the growth of crops and the growth of animals that drink it. Therefore, management of water during the storage period is important. The water management of the present invention is compared with the preceding water purification technology.

Patent document 13 is a proposal of the water purification apparatus. Water collected from the lake is filtered, purified by sludge flocculation, physicochemical control of microorganisms, membrane separation, activated sludge method, photocatalyst, solid contaminant removal, pressurization technology to suppress phytoplankton, etc. Technology.
In the present invention, static water causes oxygen deficiency and promotes the generation of sludge due to rot. Therefore, in order to preserve fresh water collected from groundwater for a long period of time, it always contains a lot of oxygen due to the structure of circulating water and the supply of nanobubbles. The purpose of the present invention is to circulate water and supply water with high functionality and high functionality, and the present invention is different from Patent Document 13 because it is a proposal as a water storage technique.

  Patent document 14 is a river purification method in which solar cells and a battery are connected together to generate fine bubbles with a blower in order to perform river purification at low cost. Although the method of generating fine bubbles by the blower has a large bubble size and is effective in supplying purified water with oxygen, it is not a nano-sized bubble generation device. The necessary devices in the present invention are a water circulation channel and a nano-sized bubble generating device.

Patent Document 15 shows a “solution reduction treatment method, oxidation treatment method, and automatic oxidation-reduction treatment apparatus” previously developed by the present inventors. The contents are reduction treatment with fine bubbles of hydrogen gas and oxidation treatment technology with fine bubbles of air, oxygen, and ozone. The ability to produce fine bubble water is microbubbles for 10 to 10 tons of water per minute, It is a technology that generates and injects nanobubbles. The present technology is the only technology that generates and jets a large amount of fine bubbles.
However, Patent Document 15 is different from aiming for long-term water storage of the water storage embankment of the present invention, and does not include installation of a circulation channel. It is a nanobubble generator that constitutes this facility.

In Patent Document 16, a purification processing water tank that constitutes a gate that opens and closes a water channel, purifies upstream water and discharges it downstream, and a fine machine maintenance generator that supplies fine bubbles to the purification water tank are installed. Although it is a technique for purifying water, the bubble generation device is a pressurized bubble generation method, and the size of the bubbles is considered to be a relatively large microbubble size, similar to the blower, from the structure of the device.
The present invention is different from Patent Document 16 because the main object of the present invention is to prevent water decay in the reservoir dike and circulate the circulation-inducing water channel and the nano-sized fine bubbles shown in Patent Document 15.

  In the present invention, technologies such as the structure of storage dikes for river groundwater sampling, seismic structure embankment that prevents liquefaction by collecting underground water, and a new water storage method for storing long-term clean and highly functional water Assemble a comprehensive system.

The first problem of the present invention is to solve the water shortage by using a water storage facility in a dike of clean river groundwater.
The river embankment is raised in proportion to the rapid increase in local abnormal precipitation due to weather changes. Aiming to provide new disaster prevention technology with a strong dike base, a safe technology against earthquakes and disasters, minimizing damage even in the event of partial damage due to an accident, and a quick and tall reservoir levee .
The second issue is the provision of basic technologies for preventing disasters such as major floods around the world that frequently occur due to global warming, preventing coastal erosion, and preventing land submergence in island areas.
The third issue is the proposal of a new water storage method and a stable water supply method that can cope with water shortages in various parts of the world.
Dams can be cited as a means of storing water, but conventional dams have many problems such as generation of turbid water due to sediment collapse, reduction of water due to wasteful evapotranspiration due to temperature rise, generation of blue sea bream and water decay.
It is necessary to secure water bottles that are free from pollution and evapotranspiration even in the catchment basin, islands, and coastal areas that cause floods every year.
In particular, when a large amount of water is stored for a long period of time, it is necessary to prevent oxygen from being spoiled by sending oxygen and to prevent the accumulation of sludge generated at the bottom of the dam lake and the tank.
In order to solve this problem, water is poured into a solid hollow embankment, and the fresh water is maintained with the water purification and recirculation device using the fine bubble nanobubbles of the patent No. 3843361 invented by the present inventor. It will prevent flooding at high heights and provide a dike with a structure that prevents the bank from collapsing even with strong water pressure.
This reservoir embankment has a steep slope that does not collapse with reinforced concrete, and can be installed even in places where a narrow embankment is required. Moreover, since it is hollow for storing water, the amount of materials such as earth and sand related to the embankment construction is greatly reduced, and it is easy to increase the height of the embankment.
Furthermore, river areas that require strong embankments have many sandy soil layers and shallow underground water and underground water, so liquefaction is likely to occur due to earthquakes. This technology will deal with the installation of underground bulkhead, pile driving, deep drain pipe installation and drainage that also serves as groundwater sampling with a pump.
In other words, clean groundwater collection technology and liquefaction prevention technology are repeated, and the embankment serves both as a water source and a disaster prevention function.
The specific contents are 1 reservoir dike structure, 2 seismic isolation liquefaction prevention technology for the base of dike base, and 3 micro-bubble nano bubble water continuous circulation purification type reservoir dike.

Claims 1 and 2 propose a reinforced concrete multi-function water-storable structure as a storage dike in order to achieve both a groundwater storage function and a dike function.
Reservoir dike is a cliff-type reservoir (clif) that forms a riverbank cliff that forms the foundation of a valley-mountain road and a dike-type reservoir bank (hereinafter referred to as “bank type PB”) having an inclined surface to be installed in a plain. type pondage bank, hereinafter referred to as Ctype PB).
In both cases, a solid riverbank is built, a water bank is built on it, groundwater is sucked up and stored, and flooding is prevented by the weight of reinforced concrete and the weight of the stored water.

Agricultural water is stored in a storage tank according to the intended use by the river filtration device pump AF and the river pumping pipe 10 using the underdrain pumping pump DP and the pumping pipe 8 of the control center CC. In particular, agricultural water is prepared for emergencies such as floods, and since a large amount of water needs to be rapidly collected by the river filtration device pump AF and the river pumping pipe 10 to increase the weight of the levee, a separate water sampling facility is provided. Industrial water and drinking water are sampled only from the groundwater through the pumping pipe 8.
In the water storage tank, water is supplied and distributed to each tank tank through a water supply and distribution pipe 9, and water is distributed outside the bank by a distribution pipe 11 outside the control center CC.

3. Outline of multi-level floor reservoir dike with cell structure Claim 2 proposed an earthquake-resistant reservoir dike with a high dike height and multi-purpose use of the top and slope.
As shown in Fig. 4 and Fig. 5, in the case of a large levee that loads huge heavy objects on the levee, the reinforced concrete columns and beams are strengthened thickly, the bulkheads connected to the columns, the ceilings connected to the beams, A long cell structure is formed on the floor, the slope is sealed with oblique beams and outer walls, and a multi-stage water storage floor is provided to enable earthquake resistance and enlargement of the dike. The shape can be 30 meters or more in both the embankment type and the cliff type.
Each floor stores water for each use of drinking water, industrial water and agricultural water, and manages it for each water. Furthermore, when planning the urban structure on the upper part as a super bank, it is possible to store urban inundation accompanying frequent guerrilla heavy rains in the basement of the urban structure and use it as a flood prevention facility.
The multi-floor water storage dike is particularly robust and has a wide slope as shown in Figs. 1 and 4, so that it is possible to install a movable photovoltaic power generation facility at the top of the dike when the water increases, and the top of the control center CC is near the top. A facility for storing the connection waterproof terminal 12 is installed along the road surface.
Connecting roads and interchanges from main roads on embankments to riverbanks, coastal roads, inland roads, etc. can be installed.

4. Description of the structure of a multi-stage floor water storage dike with a cell structure Btype PB and Ctype PB are basically the same structure, and the symbols for indicating each part are also common, so they will be described together.
As shown in FIGS. 3 and 4, I indicates a position facing the river / ocean side of the embankment, and II indicates a position facing the inland side of the embankment.
A is a river or ocean, B is an alluvium such as a sandy riverbed, and C is a base layer or bedrock under the alluvium.
The basic structure of the levee has a ceiling board 1 on which pedestals 2 and 3 having many inner walls are set on the levee base, and a road or a building is placed on the upper part. The outer surface of the embankment forms an outer shell with a strong slope structure 4, and a road protection board 29 is placed on the outer surface so that water can be stored in the embankment.
In case of unforeseen circumstances inside the levee, a partition is provided at each position of the central part and slope part, and the inner wall that divides the interior and the pillars 2 and 3 that are integral with the inner wall are connected in parallel along the shore surface to support the weight It is. These compartments and inner walls keep the water storage within a certain frame, and even if a part of the embankment breaks down, the damage is kept to a minimum within a part of the damaged part, thereby improving safety.
In addition, the compartment and the inner wall are sorted as drinking water, industrial water, and agricultural water according to the water storage position, and can be stored for each function.
Drinking water and industrial water are collected under negative pressure in the underground water drain culvert UD under the levee, collected in a water collection box CB, and sucked up by a groundwater pumping pump DP.
However, it is safe to move the groundwater drain culvert UD to the deep underground depth of the river when drinking water in an area where water sources such as factories, hospitals, domestic wastewater and livestock wastewater are nearby. is there. The sucked-up water is sent to the control center CC through the groundwater pumping pipe 8, distributed and distributed for each irrigation water, and stored from the water distribution pipe 9 to each tank of the storage dike. Draining groundwater from the levee underground drainage culvert UD and collecting in the water collection box CB is extremely important because it is one of the purposes to prevent liquefaction of the levee subsoil layer due to earthquake.
The water distribution pipe 9 of the control center CC has a role to be used when supplying water to consumers according to demand in addition to water supply to each tank.
Agricultural water storage is normally used by pumping groundwater like drinking water and industrial water, but in the flood season, it is pumped from the filtering device AF under the river premises and then pumped by the river groundwater pumping pump AP. Fill the agricultural water tank with water, increase the embankment weight, and strengthen the embankment's ability to prevent floods by increasing the weight. During the flood season, groundwater also increases, so drinking water and industrial water increase and become full.
All of these waters are normally used as water during the dry season, and the water is used effectively.
A river dog run 6 is provided below the river side I levee, and serves as a landing road, and an inland dog run 7 is provided below the inland side II levee, each having a function as a work road.
Further, the nanobubbles are continuously discharged into the river by the fine bubble nanobubble water supply pipe 31 to the river water, and the river is positively purified.

5 Strengthening the size and weight-proof function of the dike foundation The dike foundation needs to increase the weight support resistance to the deep ground and complete it. The dike stores water inside, so its weight is extremely heavy. The weight of the building and water is about 15 tons / m ² when the height of the dike is 10m, and requires a ground bearing capacity of 30 tons / m ² , and the weight is about 45 when the height is 30m. ton / ^{m 2,} it is necessary to ground the supporting force 90 ton / ^{m 2.}
Therefore, the driving of the supporting concrete pile 16 needs to reach the base or the bedrock.
The size of the dike storage volume is calculated from the relationship between the width of the base x the width of the dike upper surface x the height x the length of one section of the dike water storage. When a road is installed on the dike upper surface, it is calculated by the size of the road width. To do. For example, in the case of a dike with a height of 10 m, an upper surface width of 10 m, a lower surface width of 30 m, and a section of 500 m, it is considered that it is possible to store water of about 10,000 tons (substantially about 7,000 tons) by simple calculation.
[Height and width of the embankment]
The height of the embankment usually needs about 20m. The angle of inclination is usually 45 degrees, but the base width when the height is 20 m is the width of the upper surface of the levee such as the required road width on the levee +40 m (twice the height).
The base width in the case of requiring a height of 30 in the reservoir bank related to the big river is the area width of the top end + 60 m (double the height). Similar to the super embankment, in addition to the necessary width of the road to be constructed on the embankment, the base width in the case of construction as a site for residential areas, buildings, parking lots, shopping malls, and complex houses is the area on the necessary embankment. The width is a width of +60 m (double the height).

6 Ground strengthening technology of the reservoir levee base according to the weight of the levee and the water storage capacity Claims 3 and 4 include a comprehensive seismic base that is seismically isolated and prevents liquefaction of the ground and supports a huge reservoir levee And its infrastructure improvement technology was proposed.
Fig. 5 shows the foundation structure with heavyweight, seismic isolation, and liquefaction prevention technology along the construction procedure.
1) Driving sheet piles and installing underground bulkheads The sheet pile steel plates 13 on the river side I and the inland side II are driven to the depth of the base layer C.
Reference numeral 14 denotes a reinforced concrete partition plate, which has a function of protecting the dike base from water erosion even when the steel plate is corroded.
The underground partition plate 14 of reinforced concrete is buried in the groove by digging the groove to the base layer C using a trencher or a backhoe. Its function is to isolate the embankment from the river and inland soil layers and protect the levee ground from liquefaction such as earthquakes, even after collapse of the sheet pile steel plate 13 due to humus after a long period of time.
2) Installation of culvert drain and water collection box In addition, the culvert drain UD, river water sampling filter AF, and water collection box CB to be buried in the deep layer under the levee will be constructed in advance in order to complete the negative pressure structure. Underground construction will be carried out at a predetermined location, and foundation work will be performed to enable installation of the pumps DP and AP and the pumping pipes 8 and 10.
3) Driving a reinforced concrete pile (pile) Next, the required number of reinforced concrete piles (pile) 16 are driven into the base layer C to the inside of the partition plate, and the reinforced concrete partition plate 14 is moved to the outer sheet pile steel plate 13 by earth pressure. Press.
Since the seismic isolation panel 18 and the weight support base 19 installed on the bottom of the reservoir bank are installed on the pile 16 made of reinforced concrete inside the underground partition plate 14, the driving of the concrete pile 16 is particularly heavy. It is important to close the central part of the suspended reservoir dike.
4) A hemispherical cap 27 is attached to the top of the concrete pile 16. (See FIG. 17) Concrete pile pile) A hemispherical concrete pile is formed by inserting and fixing the convex part 28 under the hemispherical cap into the connecting concave hole part at the top of 16. (Fixing requires a connection hole with the same diameter and connection size as a custom made concrete pile.)
5) Installation of seismic reinforced concrete with a levee-crossing concrete frame connected to the underground bulkhead plate A reinforced concrete frame 15 that crosses the levee is installed and connected to the underground bulkhead plates 14 on the left and right sides of the levee, and a base structure is built. Form. (See FIGS. 7-9)
This dredging structure plays a role to fix and strengthen the underground partition plate 14 that receives the left and right energy due to the earthquake, and at the same time, receives the energy of shaking in the vertical direction of the river when the earthquake occurs and protects the dike from vertical vibrations. Have.
The function of the dredging structure is that the seismic isolation panel 18 moves between the upper and lower sliders, slides between the embankment on the foundation and the ground, receives the seismic structure, and the vibration to the foundation that supports the embankment is rubber. The cushion 20 has a function of reducing the impact.
6) Immobilization of ground and foundation flats The concrete pile 16 is dug shallowly to consolidate it, and the ground is laid down with crushed stone 21 according to the level.
On the consolidation layer 21, a binding and fixing base 17 that connects the concrete piles 16 is provided. The circumference of the concrete pile 16 is wound with a rubber buffer ring 23, and the binding and fixing base 17 is driven with a live concrete.
7) Installation of the primary seismic isolation slider On the binding base 17, the rubber sheet 24 and the rubber protective film 24 prevent the concrete from colliding with each other, absorb the impact, and make the sliding layer of clay, silt and grease. Install a slider.
8) Buffer base structure by installing seismic isolation panels A hemispherical cap 27 is fixed to the top of the concrete pile 16 so that the seismic isolation panel 18 mounted on the top can freely swing. The cap will be slipped with grease.
The concave portion of the seismic isolation panel 18 is fitted into the top of the hemispherical concrete pile 16. (Refer to FIG. 8, FIG. 10 and FIG. 11) In response to the shaking of the earthquake, the swing motion of the seismic isolation panel and the slide and swing motion by the viscous smooth surface act as a slider to release the seismic energy and exhibit the seismic isolation effect.
9) Installation of secondary seismic isolation slider and embankment base Concrete embankment base 19 is installed on the seismic isolation panel 18 through a seismic rubber cushion 20 with a thickness of 0.1 to 1m to support the weight of the reservoir. To do. A thick earthquake-resistant rubber cushion 18 having a thickness of 5 to 30 cm is sandwiched between the reinforced concrete bulkhead plate 14 and the concrete dike base 19, and a slip layer made of clay, silt and grease is installed on the embankment to cushion the roll of the dike. .
(Secondary seismic slurder)
The reservoir dike is constructed on a concrete dike base 17 that supports its weight evenly.
10) Reservoir diversion and ground liquefaction prevention technology There is a large amount of underground water penetrating from the sandy soil layer directly under the reservoir dike. The underground partition plate prevents new water from entering, and several meters below the ground are installed with 1 to several tens of porous pipes with a diameter of 0.1 to 1 m and porous concrete underdrains UD. River underground water and groundwater are sucked in under negative pressure, and forced to groundwater sampling box CB. At the same time as forced drainage, send it to the water tank.
If repeated underground water, prevention of underground water intrusion and forced drainage are continued for a long period of time, free water in the dike underground will be reduced, and liquefaction of the ground will be prevented even if an earthquake or other shaking occurs.
The forced drainage is sent to the storage dike PB through the underground water pumping pipe 8 and stored. This groundwater is used as filtered drinking water and managed by the control center CC.
In this way, in this technology, drinking water is collected and free water in the soil that causes liquefaction is removed simultaneously, thereby ensuring both water supply and disaster prevention.

7 Seismic isolation technology and seismic technology for water storage dike The seismic structure is basically a strong dredging structure with reinforced concrete frames 14 and 15 crossing under the dike connected to the underground bulkhead. As shown in FIGS. 7, 8 and 9, the ridge structure is formed by dividing the base portion of the dike with a thickness of 1 m or more, enclosing the binding fixing base 17, and the fixing fixing base 17 and the protective concrete underground partition. Combined with the plate 14, it firmly supports the dike base.
The concrete pile 16 that is in contact with the binding and fixing base 17 through the rubber cushion 23 focuses on the function of supporting the weight in the vertical direction when the ground surface is moved due to an earthquake or the like. The catching pile 16 and the fixed base 17 are prevented from being damaged by the cushion 23.
A rubber sheet or a plastic film is pasted on the fixed fixing base 17, and a smooth surface slider 26 made of clay, silt, or grease is installed thereon.
The hemispherical hole 22 of the seismic isolation panel 18 is fitted into the hemispherical part 27 at the top of the concrete pile 16 and installed. The support of the embankment weight at the position of the seismic isolation panel 18 is a structure in which the weight is supported by the top 27 of the concrete pile 16 and the smooth surface slider material 26.
As shown in FIGS. 10 and 11, the cross section of the hemispherical portion 27 on the top of the concrete pile 16 and the smooth slider 26 is easy to slide in the grease reservoir 25, and the smooth slider 26 can swing freely. is there.
The seismic isolation panel 18 is in contact with the binding and fixing base 17 via the rubber cushion 20 and the slider layer 26 made of clay, silt, and grease, and supports the weight support pressure of the water storage dike distributed to these and the concrete pile 16.
The shaking of the earthquake is transmitted to the concrete pile 16, the binding and fixing base 17 and the anchor structures 14 and 15, and the impact is transmitted to the seismic isolation panel 18 by the concrete pile 16.
The seismic isolation panel 18 eliminates the distortion generated between the seismic isolation panel 17 by sliding on the smooth surface slider material 26, and the impact of the collision with the heel structures 14 and 15 is absorbed by the rubber cushion 20. That is, it is a structure in which the distortion in the compartment is eliminated by the seismic isolation structure in the frame of the eaves structure, the solid frame and the rubber cushion.
A rubber sheet or a plastic sheet is attached to the upper part of the seismic isolation panel 18 to make it easy to slide, and a smooth surface slider 26 made of clay, silt, or grease is installed on the upper part, and the seismic isolation panel is sandwiched between the sliders.
A reservoir bank base 19 is installed on the smooth slider 26 on the seismic isolation panel 18. The upper slider 26 has a role of sliding and eliminating the distortion generated between the smooth surface slider 26 and the reservoir base. The seismic isolation panel 18 has a structure that freely slides between the upper and lower primary and secondary sliders.
Earthquake damage is a phenomenon in which a structure moves when the ground moves, and a massive heavy object is destroyed by a sudden impact due to a moment of inertia. To alleviate the impact of the levee body and distribute the gravity so that the weight of the huge levee does not hang in one place.

9 Fine bubble circulation purification reservoir dike Figure 18 shows an example of a plan view of the nanobubble circulation purification reservoir dike shown in claim 6.
Still water and oxygen-deficient water will gradually rot, so if you supply that water, the crops will grow poorly, and the health of human animals will be impaired and fish will not live.
When storing a large amount of water such as a dike, it is important to forcibly generate a water flow and supply oxygen by nanobubbles, which is efficient in activating and purifying the water. There have been many studies on the effects of water activation by nanobubbles, and many have already been demonstrated.
Water purification mainly consists of the generation of microbubbles and nanobubbles and forced water flow. The generation of nanobubbles and the forced water flow are generated by the drinking water control system FC, industrial water control system HC, and agricultural water control system JC of the control center CC. Circulate.
In particular, the position where oxygen deficiency is likely to occur is the bottom of the water tank, and it is important to cause water flow at this position. In addition, as a method for increasing the oxygen concentration of water, nano-sized bubbles containing many fine bubbles are efficient, but it is necessary to set the injection nozzle 30 of the fine bubble generating device so that the bubbles crawl the bottom surface. is there.
In the present technology, it is important that the bubble size is 100 nanometers or less.
Since microbubbles of any size are lighter than the specific gravity of water, they gradually rise to the upper layer during the flow, so fine microbubbles can carry air at a very high concentration to the water flow at a high speed at the bottom of the reservoir in the reservoir dike. It must be circulated. In the water storage, light microbubble water is mixed with the whole water during circulation, and sterilization and supply of oxygen are performed.
Microbubbles also have a sterilizing function, but the function is further increased in finer nanobubbles. In addition, nanobubbles using oxygen gas or ozone gas have a higher sterilization effect than air nanobubbles. The present invention is directed to the use of all devices that generate these microbubbles in a reservoir embankment.
Water produced by these technologies has high functionality, fast growth of plants and high quality, and rapid growth of livestock that have been drunk with this, and good health. The high effect of nanobubbles has been demonstrated, such as good.
As the fine bubble generating device, the inventor's proposed oxidation-reduction treatment device (Patent No. 3843361) produces a very large amount of nanobubble water with an injection type and a maximum treatment capacity of 10 tons per minute (currently the most treatment capacity).
