DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake-resistant water storage structure capable of storing water suitably for disaster prevention, and to a structure that can be used as a floating foundation for various structures.

[0002]

2. Description of the Related Art A water tank for disaster prevention is mainly used for fire prevention, and is also used for drinking in an emergency. By the way, even if it can be used without any problem in the case of a normal fire, if a fire occurs due to a large earthquake, a normal water storage tank may be almost useless. The reason is that the water tank is destroyed by the shaking during the earthquake and the water flows out, making it impossible to use the water storage effectively.Also, traffic stops functioning and the fire engine can not use the water storage tank to access the water storage tank. This is because it is impossible.

For this reason, a water tank having an earthquake-resistant design that can withstand a large earthquake is required, and a small-sized water tank can be provided nearby instead of providing a large-scale water tank at a remote place. It has become. As such a water storage tank, a structure in which a water storage space is provided in the ground to confine water underground has been conventionally considered. For example, there is a method in which a large-diameter pipe is connected and buried underground, and water is stored in the pipe.

[0004]

As described above, the most important condition when considering the structure of a water storage tank that can withstand a large earthquake is to have sufficient resistance to shaking. In the method of burying a large-diameter pipe in the ground, a method of connecting the pipes with steel wires and attaching them with a certain degree of elasticity is used, but if the ground shakes greatly, I can't stand it. Also, even in the case of a structure with a buried storage tank and a lid attached, the lid may come off due to pitching or rolling in the event of an earthquake, or water may be blown out of the ground due to the rush of water. Things happen.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem of a water storage tank.
Providing an earthquake-resistant water storage structure that has strength and flexibility to withstand rolling, etc., is not easily destroyed by an earthquake, has safety and reliability as a water storage tank, and is easy to perform construction work Is what you do.

[0006]

To achieve the above object, the present invention comprises the following arrangement. That is, a water storage unit in which a partition plate formed in the shape of a rectangular plate is combined in a tubular shape having a triangular shape in a plane is connected in a honeycomb structure, and the end surfaces of the partition plates are abutted with each other to form a linear arrangement with each other. A wall structure integrated by binding each other with a steel wire and supporting the wall structure,
It has a bottom structure which closes an opening of the bottom between the partition plates, and a lid structure which closes an upper opening between the partition plates of the wall structure. By making the structure a honeycomb structure, the structure can be formed with high strength, and the impact load can be suitably reduced by forming a flexible structure in which the end faces of the partition plate abut against each other.

[0007] Further, the partition plate is assembled by abutting a rigid ring against an end face of the partition plate.
Since the partition plate is formed in a cross-girder shape by combining a horizontal frame and a vertical frame, and each member is connected via a menase hinge, the flexibility can be further improved and an impact load can be easily released.

Further, the bottom structure is formed in an arch shape having a convex cross section, and a bottom plate is provided at the top with which the lower end surface of the partition plate abuts. Thus, even if a large impact load is received, the water storage structure can be prevented from being broken. Further, the bottom plate is divided into three portions corresponding to the three partition plates constituting the water storage unit, and a key block for supporting these bottom plates is provided at the center of the bottom of the water storage unit. Accordingly, the bottom surface can be received firmly and with reduced impact. Also, the bottom plate is a top portion where the partition plate abuts, a pair of members on both sides sandwiching the top portion are connected via a menase hinge, and on a foundation supporting the bottom plate, according to the arch shape of the bottom plate, A bulge supporting the bottom plate is formed, and a seismic isolation layer is provided between the bulge and the foundation and the bottom plate. With the buffer ball interposed therebetween, it is possible to extremely effectively reduce the impact load at the bottom plate portion. Further, the lid structure is formed in a downwardly convex arch shape, and a top plate on which the upper end surface of the partition plate abuts is provided on the lower surface of the arch. Can be obtained.

[0009]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing a state in which an earthquake-resistant water storage structure according to the present invention is installed, and shows the earthquake-resistant water storage structure in a partially broken manner. This water-resistant water storage structure forms a storage space by installing the water storage unit 10 having a regular triangular planar shape adjacent to the water storage unit. FIG. 2 shows a plan view in which ten water storage units 10 are installed adjacent to each other. The seismic water storage structure according to the present invention is characterized in that a number of water storage units 10 can be connected in series as described above, and the arrangement can be appropriately selected according to the area and shape of the installation location. Thereby, for example, it can be installed and stored underground in a park. In addition, it is of course possible to use the water storage unit 10 alone.

As shown in FIG. 2, the state in which the water storage units 10 are connected to each other has a honeycomb structure, which is advantageous in that the structure is robust. FIG. 1 shows a state in which the earthquake-resistant water storage structure of FIG. 2 is broken along line AA. Each water storage unit 10 includes a bottom structure, a wall structure, and a lid structure. The bottom structure serves as a support base for the water storage structure, and supports the wall structure and the lid structure.
The wall structure has a connecting means for connecting a partition plate 42 constituting a wall portion of the water storage unit 10 and an adjacent partition plate 42. Note that the partition plate 42 has a structure in which water communicates between the adjacent water storage units 10, and has a structure in which only the outermost wall surface of the structure is entirely closed. The lid structure has a structure that closes the upper opening of the water storage unit 10 and withstands earth pressure.

As described above, the wall structure of the water storage unit 10 is formed by combining three partition plates 42 into a triangular planar shape. Therefore, the internal volume of the unit water storage unit 10 is determined by the size of the partition plate 42. The size of the partition plate 42 may be appropriately selected in consideration of the required water storage amount, construction work, and the like. In the present embodiment, the partition plate 42 having a long side of 7 m and a short side of 3.5 m is used. . Thereby, the internal volume of the unit water storage unit 10 becomes about 60 m ³ . The minimum unit water storage tank only needs to have this amount of water.

FIGS. 3 and 4 are front views of a partition plate 42 constituting the wall structure 40. FIG. 3 is used for a part that partitions the adjacent water storage unit 10, and FIG. 4 is used for the outermost wall. In the partition plate 42 shown in FIG. 3, the upper and lower horizontal frames 43a, 43b are connected by vertical frames 44a, 44b, 44c to form a rectangular frame, and the vertical frames 44a, 44b, 44c are connected by connecting frames 45a, 45b. . The partition plate 42 is formed in a cross-girder shape by the configuration of the horizontal frame, the vertical frame, and the connection frame, and the adjacent water storage units 10 communicate with each other at an opening surrounded by the horizontal frame, the vertical frame, and the connection frame.

The partition plate 42 is integrally formed in a factory in advance by concrete molding, and is assembled on site by connecting with the partition plate 42 constituting another water storage unit 10.
The partition plate 42 includes horizontal frames 43a and 43b and vertical frames 44a and 44.

6 to form a flexible structure.
In order to connect the horizontal frames 43a, 43b and the vertical frames 44a, 44b, 44c via the menase hinge 46, first, each of the horizontal frames 43a, 43b is connected to the menase hinge 4 using a mold.
6 is buried and solidified, and then the horizontal frame 43
What is necessary is just to arrange | position the formwork for vertical frame formation in alignment with a, 43b, and to pour concrete into a formwork and to solidify. Connecting frames 45a, 45b and vertical frames 44a, 44b, 44
The same applies to the case where c is linked via the menase hinge 46.

In FIG. 3, reference numeral 50 denotes a steel wire (pc steel wire, carbon fiber wire, etc.) for binding the adjacent partition plate 42 in the longitudinal direction when the partition plate 42 is assembled. The steel wire 50 is used for assembling the partition plate 42, and a sheath for passing the steel wire 50 is embedded in the partition plate 42 in advance. The steel wire 50 has upper and lower horizontal frames 43a, 43b.
And three central frames 45a and 45b. In FIG. 3, reference numeral 52 denotes an abutting rigid ring mounted between the end faces of the adjacent partition plates 42 when the partition plates 42 are assembled. The abutting rigid ring 52 has a flexible structure (movable structure) in which it is brought into contact only between the end faces of the adjacent partition plates 42, so that the pressure generated between the adjacent partition plates 42 is reduced and buffered. Play. The abutting rigid ring 52 is also mounted when the partition plate 42 is assembled.

FIG. 4 shows a partition plate 42a used for the outermost wall.
4 (a) is an end view, and FIG. 4 (b) is a front view. The partition plate 42a for the outer wall is formed into a single closed plate by concrete molding. The central portion of the outer surface is formed in a mountain shape with a large thickness in order to maintain sufficient strength to withstand water pressure, earth pressure, and the like. Also in the case of the partition plate 42a, the rigid ring 52 is attached to the end face and the sheath for passing the steel wire 50 is embedded. A step is formed on the end face of the partition plate 42a with which the abutting rigid ring 52 abuts to mount the abutting rigid ring 52 thereon.

FIG. 5 shows a part of a water storage structure formed by combining partition plates 42. The figure shows a plan view of a state where the partition plate 42 is supported on the bottom structure. Here, the assembly structure of the partition plate 42 will be described. As described above, the wall surface portion of the water storage unit 10 is constituted by the partition plates 42, and these partition plates 42 are fixed in a triangular combination in units of three. The partition plates 42 are fixed in a linear arrangement with each other.
Through a steel wire 50, and apply high tension with a jack to bind them together. The adjacent partition plates 42 are abutted via the abutting rigid rings 52, and the ends of the six partition plates 42 are concentrated on one abutting rigid ring 52. Since the partition plate 42 is combined into an equilateral triangle,
Around the abutting rigid ring 52, partition plates 42 are arranged radially at an equal angle.

A space is created between the end faces of the partition plate 42 which is arranged with the end faces abutting via the abutting rigid ring 52. This space is filled with a seismic isolation material 54 such as liquid rubber or bentonite. This seismic isolation material 54 is used for the partition plate 42.
The use of a material having a different elastic modulus from that of the butting rigid ring 52 has an effect of preventing resonance. In the present embodiment, the partition plate 42 is abutted against each other via the abutting rigid ring 52 and is bound by the steel wire 50 because the partition plate 42 has a flexible structure and an impact load is applied to the structure due to an earthquake or the like. When acted upon,
This is because the stress is released between the partition plates 42 and the load can be avoided. Further, the seismic isolation member 54 also has an effect of reducing the impact between the partition plates 42 and preventing water leakage on the outermost wall portion of the structure.
These steel wires 50, butting rigid rings, and seismic isolation members 54
Constitute the connecting means of the wall structure.

Although FIG. 5 assumes a configuration in which a plurality of water storage units 10 are connected in series, if the water storage units 10 are used alone, the rigid ring 52 is abutted against the partition plate 42 as an adjacent partition plate 42. A narrow dummy partition plate 42b that can be tightly bound by the steel wire 50 by interposing the steel wire 50 may be used. Also, when assembling the partition plate 42a of the portion constituting the outermost wall of the water storage structure, the abutting rigid ring 52
May be disposed in the middle, and a dummy narrow partition plate 42b may be arranged outside the intermediate member and tightened by the steel wire 50. As described above, by making the structure of the partition plate a flexible structure and a honeycomb structure, a water storage structure having extremely excellent earthquake resistance can be obtained.

FIG. 6 shows the structure of the bottom structure 20 that supports the partition plate 42 described above. The bottom structure 20 is mainly composed of a base 21 serving as a base of the entire water storage structure and a bottom plate 22 disposed on the base 21. The bottom plate 22 is a member with which the lower end surface of the partition plate 42 abuts, and is characterized in that a portion with which the partition plate 42 abuts has an upwardly convex cross-sectional shape as shown in the figure. The cross-sectional shape of the bottom plate 22 is made to be convex upward in order to receive a load acting on the bottom plate 22 as a compressive force. Although the bottom plate 22 is made of concrete, since the concrete material has an extremely high strength against compressive force, it is possible to firmly receive the impact load due to an earthquake or the like by making the bottom plate 22 into an arch shape. .

The bottom plate 22 is connected to the left and right bottom plates 22, 22 via a menase hinge 46 at the center. This makes the entire bottom plate 22 arch-shaped, and
This is because the load applied to the bottom plate 22 can be dispersed by imparting flexibility to avoid impact. That is, the bottom structure supporting the partition plate 42 has a structure having both strength enough to withstand an impact load and a function of dispersing and relaxing the impact load. Adjacent bottom plates 22 are fixed to each other through steel wires 50 in the same manner as the partition plates 42 are connected.

FIG. 5 shows a state in which the bottom plate 22 is viewed from the plane. As shown, the bottom plate 22 is a partition plate 42
The key block 23 is placed at the center to fill the bottom surface. The key block 23 is arranged at the center of the water storage unit 10 in order to distribute the load from the three bottom plates 22 without concentrating it at one point in the center and to form the divided bottom plate 22 suitable for transportation or the like. In order to When water pressure is applied outward from the inside of the water storage structure, the key block 23 can be used to prevent this. Reference numeral 24 denotes a pit for discharging mud and the like.

As shown in FIG. 6, the bottom plate 22 is placed on a foundation 21. Since the bottom plate 22 has an arch shape in which a portion supporting the partition plate 42 is convex upward, a bulging portion 21 a is formed on the base 21 so as to support the convex portion of the bottom plate 22. Foundation 21
Is formed by casting concrete at the construction site. At this time, the swelling portion 21a is formed or a concrete product previously formed in a factory in the shape of the swelling portion 21a is used as a base 2.
It is formed integrally with the concrete. The bulging portion 21a is formed in accordance with the arrangement of the partition plate 42 arranged on the honeycomb, so that the bulging portion 21a is formed in a continuous waveform on the base 21. Reference numeral 26 denotes a seismic isolation layer laid on the foundation 21 and the bulging portion 21a. The seismic isolation layer 26 is provided for the purpose of reducing the impact load in the event of an earthquake or the like, and is made of rubber or a material having a buffering action such as urethane or bentonite.
The seismic isolation layer 26 is disposed between the bottom plate 22, the foundation 21, and the bulging portion 21a.

The bottom plate 22 is simply placed on the base 21 and the bulging portion 21a with the seismic isolation layer 26 interposed therebetween. This is a state where the structure is supported in a flexible (movable) state with respect to the base. Becomes In other words, when a thrust load or a lateral swing load acts on the structure due to an earthquake or the like, the connection portion and the support portion are made flexible so that the impact load is released and the structure is not destroyed. Like that.

When an impact load is applied to the structure, it is effective to allow the bottom plate 22 to move slightly in order to release the load. For this reason, it is preferable to mount a cushioning ball 28 having a hardness similar to that of a golf ball and having elasticity between the lower surface of the bottom plate 22 and the seismic isolation layer 26. The shock absorbing ball 28 itself deforms flat when an impact load is applied and acts to relieve the load, and also acts to shift the bottom plate 22 in the lateral direction on the bulging portion 21a to effectively reduce the load. ease. If dimples are formed on the outer surface of the buffer ball 28 like a golf ball, an effect of overrunning the dimple when the buffer ball 28 rotates is generated, and there is an effect of dispersing the load force vertically and horizontally to absorb energy.

The partition plate 42 is configured such that the lower end thereof is in contact with the top of the bottom plate 22 and is simply placed on the bottom plate 22. Therefore, when a thrust load acts on the structure during an earthquake or the like, there is a possibility that it will move up and down independently of the bottom plate 22. Therefore, the bottom plate 22 may be provided with a guide body 30 for guiding the lower end of the partition plate 42.

A lid structure is provided above the partition plate 42, that is, on the opening side of the water storage unit. As shown in FIG. 6, this lid structure is arranged by reversing the above-described bottom plate 22 in the vertical direction. That is, the partition plate 42
The top plate 60 is formed to have a downwardly convex shape in order to receive a load acting in a pushing direction from the upper end edge as a compressive force. The top plate 60 is connected via the menase hinge 46 to form a flexible structure.
The connection of the 0s is the same as that of the bottom plate 22.

Since the earthquake-resistant water storage structure of this embodiment is buried and installed underground, after assembling the foundation 21 and the partition plate 42, the top plate 60 is assembled and covered with soil as shown in FIG. The top plate 60 is supported from above by the earth pressure. The top plate 60 is provided with a manhole 62 so that water can be taken in and out. FIG. 7 shows the bottom plate 22 and the top plate 60.
2 shows a cross-sectional arrangement of the device. A key block 64 is also provided at the center of the top plate 60, and a manhole 62 is formed in the key block 64. The bottom plate 22 is inclined so as to gradually project upward in the direction toward the partition plates 42 on both sides, and the top plate 60 is inclined so as to gradually project downward in the direction toward the partition plates 42 on both sides.

Reference numeral 32 denotes a support plate attached to the lower surface of the key block 23 of the bottom plate 22, and 66 denotes a key block 6 of the top plate 60.
4 is a support plate attached to the upper surface of the fourth embodiment. These support plates 3
2, 66 are steel wires 5 between the upper and lower key blocks 23, 64.
0 is provided to tighten the space between the key blocks 23 and 64. When the space between the upper and lower key blocks 23 and 64 is tightened, the tightening force acts as a compressive force on the bottom plate 22 and the top plate 60, and even when an internal pressure is applied to the structure, a holding force capable of resisting the internal pressure is generated. Can be. When water is supplied from the tap to the water storage structure, the tap water pressure sometimes acts as an internal pressure on the structure. In such a case, it is effective to tighten the space between the upper and lower key blocks 23 and 64.

It is possible to use a structure in which the structure is reinforced by utilizing the tightening force of the steel wire 50. That is, in the present invention, the partition plate 42 is arranged in a honeycomb structure in units of triangles, but a reinforcing wall body is formed on the outer wall surface of the outermost partition plate 42 so that the outer peripheral shape of the water storage structure is entirely circular. By attaching the steel wire and winding the steel wire around the outside of the wire, the structure can be held more strongly, and a structure capable of sufficiently withstanding the internal pressure can be obtained.

Further, since the seismic water storage structure according to the present invention has a sealed structure as a whole, and the specific gravity of water is lower than that of soil, gravel, etc., the entire water storage structure is a floating foundation, a three-dimensional reinforcing structure. It can also be used as a body. In the case of a soft ground, it is possible to improve the soft ground by using a floating foundation whose buoyancy of the structure is appropriately designed. In addition, a triangular honeycomb structure using a plate body can be used as a three-dimensional reinforcing structure on soft ground by attaching a lid to the upper part and burying it in the soil.

In the seismic water storage structure of the above embodiment, the bottom plate 2
2 and the top plate 50 have an extremely rigid structure with an arch shape. As a method of forming such an arched structure, a method of forming the bottom plate 22 and the top plate 50 by combining the hexagonal columnar bodies 70 shown in FIGS. The hexagonal prism 70 used here to form an arch-like structure is formed in a truncated hexagonal pyramid having a tapered side surface. FIG. 8 shows a state where the hexagonal columnar bodies 70 are combined as viewed from the plane. By using the hexagonal columnar body 70, a flat surface can be spread without gaps. 72 is a hexagonal columnar body 70
Are wires for binding and fixing each other. In the illustrated example, the entire surrounding hexagonal columnar body 70 is integrally fixed through wires 72 in three diagonal directions of the central hexagonal columnar body 70.

FIG. 8 shows a state in which seven hexagonal pillars 70 are arranged for the sake of explanation. However, when the bottom plate 22 and the top plate 60 are actually formed, a large number of hexagonal pillars 7
0 is arranged as a structure. The hexagonal columnar body 70 is made of concrete, wood, or the like, and is formed into a hexagonal frustum of a predetermined size. As shown in FIG.
When the hexagonal columnar bodies 70 are connected continuously, the upper and lower parts of the hexagonal columnar body 70 are connected by wires 72 respectively. At the upper and lower end surfaces of the hexagonal columnar body 70, a through groove 70a for passing the wire 72 is formed. The through groove 70a is formed at a diagonal position of the hexagonal columnar body 70 as shown in FIG. By forming the through groove 70a in this manner, the wires 72 are arranged linearly.

As shown in FIG. 8, a wire 72 is wound around the hexagonal columnar body 70 and fixed to the outer periphery of the hexagonal columnar body 70 in the structure constituted by the hexagonal columnar bodies 70. In this way, the entire hexagonal columnar body 70 is integrally bound and supported by the wire 72. Note that a high-strength material such as carbon fiber is preferably used for the wire 70.

As shown in FIG. 9, by combining hexagonal prisms 70 formed in a truncated hexagonal shape, a structure having an arched cross section can be obtained. As described above, an extremely high-strength structure can be obtained by forming an arch structure. In this case, a material having a high compressive strength such as concrete can be suitably used as the hexagonal columnar body 70. For example, carbonized wood which is obtained as a lightweight, high-strength and environmentally resistant material by performing carbonization is suitable. Can be used for Further, when forming an arch structure, not all hexagonal columnar bodies 70 need to be formed in a truncated pyramid having the same taper angle. Adjust the arch shape by adjusting the taper angle appropriately,
It can also be flat.

As described above, by forming the hexagonal columnar bodies 70 in contact with each other, a compressive force acts between the hexagonal columnar bodies 70, but the hexagonal columnar bodies 70 are tightly bound by the wire 72. Thereby, a truss structure by the wire 72 is realized. That is, when an external force such as a torsional force in the lateral direction acts on the truss structure by the wire 72, the truss structure can receive the external force as an arch action by the compressive force and the tensile force. Thus, sufficient strength can be exerted against external actions such as the above.

When the bottom plate 22 and the top plate 60 are constructed on site, a hexagonal columnar body 70 which has been concretely formed in a factory or the like can be assembled and constructed, or concrete can be poured on site to perform construction. In the case where concrete is poured on site to perform the construction, a forming frame for forming the hexagonal columnar body 70 is used. The molding frame is preferably made of a corrosion-resistant material such as a resin molding frame or a molding frame coated with a ceramic material such as titanium oxide, which is harmless to the environment.

In the on-site construction, the forming frame is previously connected to the wire 7.
2 and the wires 72 are connected to each other in a state where the water is fully filled in the molding frame formed with the bottom and the molding frame is maintained.
Then, concrete is replaced by concrete while pouring concrete into the molding frame and removing water. By pouring water into the molding frame before pouring the concrete, the molding frame can be kept in shape by the wire 72, and can be replaced without breaking the shape by the operation of pouring concrete. Although the molding frame is left as it is on the structure, there is no particular problem in terms of durability, strength and the like. In the case of on-site construction, there is an advantage that concrete can be poured into a required arch shape while a molding frame is installed at the site.

[0038]

As described above, the earthquake-resistant water storage structure according to the present invention can be formed as a very strong structure by forming the partition plate into a triangular honeycomb structure, and the water storage tank can be arbitrarily arranged with an arbitrary volume. Can be easily configured. In addition, by forming the partition plate or the like in advance, on-site construction can be easily performed. In addition, since the partition plates have a flexible structure in which the end faces abut against each other and are tied up with a steel wire, it is possible to appropriately mitigate an impact load such as an earthquake and prevent the structure from being destroyed. In addition, by forming the bottom plate supporting the partition plate into an arch shape in cross section and receiving a shock load as a compressive force, it is possible to have a structure that can sufficiently withstand shocks such as earthquakes, and it has excellent earthquake resistance It has significant effects such as being able to be provided as a water storage structure.
