Specification

Floating body construction method of storm surge floating building

Technical field

[0001] This invention protects human lives and precious assets from floods caused by large tsunamis, typhoon storm surges, or heavy rains caused by a large earthquake, and a floating construction method for floating storm surge buildings where people live safely About.

Background art

[0002] December 26, 2004 A major submarine earthquake off the coast of Malaysia caused a major tsunami in the coastal areas of the Indian Ocean coastal countries, resulting in delayed transmission of information. Ten thousand people died.

There were no evacuation facilities for tsunami damage in the traditional coastal area, but there was no way to do it other than evacuating to the upper floors of small mountains and high-rise buildings.

Governments and local governments concerned with the tsunami are now developing software to predict the occurrence of major earthquakes, develop detection methods for detecting tsunamis as soon as they occur, and transmit them to many people. Focus on building the surface.

[0003] How quickly to escape to small mountains and high-rise buildings is a way to stop damage and reduce

[Mame.

However, there are no small mountains and high-rise buildings! There are many plains, rural areas, and even the coastal areas where it is difficult to evacuate quickly because of the long distance.

Along with the construction of information transmission and communication means for the occurrence of tsunamis, the development of hardware and other equipment and facilities as a means of evacuation in the event of a tsunami is also an extremely important issue.

In addition, due to typhoon storm surges that hit several times a year and river flood damage due to torrential rains, people living in the lowland have suffered enormous human property damage every year due to storm surge inundation and flood inundation.

[0004] Even in Japan, there is a high possibility that the Nankai earthquake and Tonankai earthquake will occur at the beginning of this century! Therefore, tower-type shelters with a steel structure of more than 10 meters have been proposed. (See Patent Document 1)

Patent Document 1: Japanese Patent Application Laid-Open No. 2004-339920 There is a question whether it is possible to climb a refuge at a height of more than 10 meters using stairs, and there is no guarantee that the height of the tsunami is within the height of the tower over a few dozen meters. So we are still in the stage of popularization!

Disclosure of the invention

Problems to be solved by the invention

[0005] An object of the present invention is to provide a high-tide levitation building that can escape difficulty just by entering an evacuation building installed on a flat ground without climbing a high place of several tens of meters during evacuation.

In addition, since the use frequency of the building against the tsunami of the present invention is extremely rare, it is rarely used as a tsunami evacuation building. Therefore, it is intended to provide a storm surge floating building that can be used for various purposes other than evacuation. Let it be an issue.

Another object of the present invention is to provide a high tide levitation building that can support lifesaving in any high water level tsunami of more than a dozen meters or more, for example, a hundred meters or more.

Furthermore, the objective is to provide general buildings and residential houses that are free from the danger of flooding inundation due to storm surges and river flooding floods that frequently hit tsunamis.

Still another object of the present invention is to propose and disclose a floating body construction method for the above-mentioned storm surge floating building.

Means for solving the problem

[0006] This is a floating structure with a floating structure that prevents flooding of the building against storm surge floods such as tsunami, typhoon and river flooding. In the method of building an object, a method for constructing a floating body of a storm surge building characterized by the following steps 1 to 4.

1. A pedestal that can withstand the aerial weight of a pedestrian floating body will be formed on the bottom of the foundation, and a foundation will be constructed that is adjacent to the pedestal and has a lower maintenance passage than the pedestal.

2, Assemble and construct a base type floating body in the space above the base.

3, Introduce three or more jacklifts in the maintenance passage, operate the jacklifts to raise the trolley type floating body, and perform surface treatment processing of the bottom surface of the trolley type floating body. 4. After the above steps are completed, operate the jack lift to lower the floating body and place it on the upper surface of the base.

[0007] The present invention is an equipment for a refuge body that protects human life and movable property against floods such as tsunamis, typhoons, and river floods. Evacuees evacuate on the floating body according to the flood information. It can also be configured.

In addition, it is a floating construction method for floating storm surge buildings that provide safe, ordinary buildings and residential spaces that are not flooded in response to frequent floods caused by typhoons and river floods.

The trolley type building of the floating body construction method of the present invention includes all the equipment inhabited by a person on the floating body, and is simply provided with a handrail on the space below the floating deck and the floating body. It shall include all living spaces integrated with the floating body.

[0008] In the present invention, a solid foundation is constructed with concrete at a necessary construction place, and a floating body of a carrier structure is mounted thereon.

The floating body is provided with an anchor pole that also projects the bottom force of the floating body, and a pole hole can be drilled on the surface so that the anchor pole is inserted into the foundation.

According to this structure, if a high water level such as a tsunami, typhoon storm surge or river bank inundation due to torrential rain occurs, and if the water level exceeds the floating waterline, the floating body will lift the buoyancy from the water surface in the direction of separation and rising. receive.

The floating body rises as the water level rises, but the anchor pole protruding downward from the floating body and the side wall of the foundation pole hole are fixed in contact with each other, and the floating body receives horizontal force in the flowing water but does not flow, but vertically To surface.

Just as the lower end of the anchor pole is inserted into the base pole hole, a cylindrical protrusion can be embedded in the bottom of the foundation instead of the pole hole, and the anchor pole lower end cylinder can be inserted into the cylindrical protrusion. The key point is that the anchor pole is locked to the bottom of the foundation.

[0009] Further, in addition to the first anchor device for preventing horizontal movement of the floating body caused by running water by the anchor pole and the pole hole, the following second anchor device may be provided. The second anchor device is as follows. The floating body is placed on the pedestal, and a guide wall extending in the vertical direction integrally with the foundation is formed on the side surface of the floating body, and the guide wall is configured to be in contact with the side surface of the floating body with a slight gap.

When the high water level is generated by the storm surge and the flowing water flows into the foundation maintenance passage, the floating body floats up, but the floating body is in contact with the guide wall. Ascends and prevents horizontal movement due to running water.

[0010] In the tsunami, the first wave arrives and the water level rises, then it becomes a sudden ebb tide, and the destroyed parts of the land are pulled to the sea, and then the second and third storm surges arrive. Many.

In the case of the above-mentioned first anchor device, if the height of the storm surge is within the length of the anchor pole, the floating body will move up and down with the water level without being swept away, and if the water level drops, the floating body will return to its original position. Is enshrined.

If the water level rises further and the floating body rises and the anchor pole lower end comes out of the pole hole force, the anchor device composed of the anchor pole and the pole hole will not be anchored, and the floating body will be washed away by tidal current and flood water.

[0011] The floating body becomes free when the anchor pole is suspended, and it is tossed in the flow, but it does not sink and sink, and there is a high possibility that life on the floating body will be saved.

In the case of the second anchor device, when the four side surfaces of the floating body and the guide wall are in contact with each other, the structure is simple, and the anchor pole does not have a risk of bending and exhibits a strong anchoring action.

If the contact with the floating body side where the height of the storm surge is higher than the upper end of the guide wall is released, the floating body will be washed away by the tidal current and flood water as in the case of the first anchor device. It will not sink unless it hits and breaks.

[0012] Next, the storm surge levitated building of the present invention is a land-based building, and large facilities such as shipyards can be used, and a large floating body must be constructed by local construction in an urban area! /.

For this purpose, it was necessary to develop special construction means and methods to build huge floating bodies and buildings with small equipment that can be easily moved.

The floating body construction method of the present invention is inserted into a maintenance passage provided on the basis of a movable small jack lift, and theoretically, three or more jack lifts are lifted and lowered to lift the bottom of the floating body. It is possible to achieve a surface treatment force that is equal to the outer force of the part.

The invention's effect

[0013] Recently proposed! The above-mentioned tsunami evacuation device has a steel structure with a height of several tens of meters, and has an evacuation platform with handrails of about 10 meters square on the top and stairs for ascending and descending. It is provided.

With this evacuation device, it is extremely difficult and time-consuming for a large number of people, more than 100 people, to go up the stairs of more than a dozen meters upon receiving tsunami information. The storm surge levitated building constructed by the method of the present invention has a buoyancy equal to the weight of water below the waterline at the bottom of the hull. receive.

(It is a building constructed on land, but when it is inundated, it becomes a ship that floats on the water.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the following examples illustrate one aspect for concretely illustrating the technical idea of the present invention, and the present invention is not limited to only the examples. In order to facilitate understanding of the present invention, the background of the present invention will be described prior to the examples.

[0015] The trolley type floating body used in the storm surge levitated building constructed by the method of the present invention has a structural bottom that is almost the same as the deck and has a shallow draft to obtain the required buoyancy. Satisfying with a low-profile flat hull structure.

Therefore, when evacuating on the floating body, the elevating passage can also be arranged on the front and rear sides of the floating body where the height of the floating body is extremely low, and many people can get in parallel at the same time when going up and down the stairs.

Furthermore, in the present invention, since the foundation has a container structure having a side wall and a bottom surface, the container-like foundation is buried below the ground, and the height of the bottom surface is lowered below the ground, so the floating body is placed on the bottom base. Since it is a structure and the height of the floating deck is the same as the ground GL and can be set freely, it is not necessary to climb to a high place by stairs.

Therefore, there are many storm surge levitated buildings in a short period of time compared to the tower type refuge described above. Personnel can be evacuated.

[0016] Further, the frequency of use of this evacuation floating body is only once every several decades or hundreds of years. For this purpose, other than evacuation except for tsunami and typhoon storm surge, It is desirable to use multi-purpose equipment that can be used for various purposes, and effective use of land and equipment is planned.

In other words, even if this base boat type floating body is installed and the land of a certain area is occupied, the floating body will be dedicated to the plane area of the container type foundation that enters below the ground and the floating body enters.

In addition, a passage from the deck to the inside of the floating hull can be provided to effectively use the volume below the deck as a basement.

On top of the pontoon type floating body, most of the buildings such as the meeting place 'Hotel · Restaurant' Kindergarten · School · Residential housing, etc. can be equipped with general homes that can be equipped with safety.

[0017] When used for tsunami evacuation, even if a rapid seawater level rises and a tidal current occurs at a high flow rate in the direction of land on the sea, the storm tide building with the first anchoring device will be the foundation of reinforced concrete. The floating body is fixed by the drilled pole hole and the anchor device by the anchor pole, so that it will not flow into the tidal current.

In a high tide levitated building with a second anchor device, a floating body is placed on a pedestal, and a guide wall extending in the vertical direction integral with the foundation is formed on the floating body side surface so that the guide wall contacts the floating body side surface. Configure.

When the high water level is generated by the storm surge and the flowing water flows into the foundation maintenance passage, the floating body floats up, but the floating body is in contact with the guide wall. It is designed to float and prevent horizontal movement by running water.

[0018] As the water level rises, the floating body rises by receiving buoyancy from the inundation, but rises vertically without being swept away by the anchoring action of the anchoring device.

In a storm surge such as a tsunami, the water that has flowed from the sea to the land will flow down from the land to the sea as the next rapid tide. Also in this case, the floating body is prevented from moving in the horizontal direction by the anchor device, and the floating body itself descends vertically downward as the water surface descends. It will return to its original position without being washed away, and the people on the deck and the buildings built on the floating body will be protected.

[0019] When the water surface of the tsunami is extremely high and the anchor pole is pulled out of the anchor hole of the foundation by the first anchor device, the floating body becomes free and is tampered with the movement of the seawater.

Even if the floating body side and guide wall are removed by the second anchor device, the floating body becomes free and is tossed with the movement of seawater.

In either case, however, the floating body will not sink unless it collides with a large structure on land, etc., and the human life on board and the building on the floating body are protected.

[0020] The present inventor has filed an invention and device of the same kind as the present invention in a prior application as follows.

The present invention relates to an improvement of the above-described invention and device, and was created in consideration of maintenance while expanding the range of use more specifically and practically.

The present invention also provides a method for constructing a floating body of a high-tide levitation building in consideration of the specific production method of the present invention and improving the configuration suitable for the production method.

[0021] The present invention particularly relates to a construction method of a pontoon type floating body at a construction site. The pontoon is a large crane capable of being lifted and moved by several tens of tons or more, a rail type stern or It is built in shipyards such as dry docks and floating docks. It was towed offshore.

The present invention is a construction work where the construction site changes one after another when the construction of a shipyard-like facility is completed in an inland land building, so the technology for building a barge at the shipyard cannot be applied, and a new construction I had the power to create a method.

Example

[0022] Fig. 1 is a bird's-eye view for explaining the configuration of the storm surge building (10) of the present invention and the operating principle during flooding.

The foundation made of reinforced concrete (4) is mostly buried in the ground, and is a container-structured pool type with a foundation bottom (18) and side walls (15) on all sides. The top of the side walls is slightly higher than the ground (9). Is formed.

Three rectangular parallelepiped bases (5) are formed on the bottom surface (18), and pole holes (3) into which anchor poles (2) to be described later are inserted are drilled at the four corners of the base.

A maintenance passage (6) is formed between the pedestal (5) and the pedestal in the same plane as the bottom surface (18), and a hydraulic cylinder type jack lift (8) is placed. The jack lift is a device for jacking up the floating body (1), which will be described later.

A hollow floating body (1) with a bottom plate, four side surfaces, and a top surface made of steel plate, etc. has a loading platform (1 1) inside, and anchor poles (2) are pivotally attached to the four corners. Yes.

The anchor pole (2) is a telescope type and expands and contracts vertically downward. In the figure, the anchor pole (2) extends and the lower end is inserted into the pole hole (3).

[0024] The pedestal (5) of the foundation (4) has a load bearing capacity that supports all the aerial weights of the floating body (1) and the building constructed on it, and the normal floating body (1) is placed on the pedestal. It is burned.

Figure 1 shows the situation during flooding. When the water level rises to the water surface line (14) and the floating body (1) rises, the anchor pole (2) extends downward and only its tip is at the top of the pole hole (3). It is in contact with the part.

Due to inundation such as tsunami, typhoon storm surge and river inundation, floating body (1) rises and the floating body (1) is pushed by horizontal force by the flow speed, but floating body (1) Absent.

Anchor pole (2) integrated with floating body (1) Force receiving force Anchor pole (2) and pole hole (3) abut and the force acts on pole hole (3) to act on foundation (4), but the foundation (4) integrated with the earth ground is immobile. And the floating body (1) is not washed away.

[0025] The floating body (1) moves up and down according to the rise and fall of the water level by the anchor action where the anchor pole (2) and the pole hole (3) abut against each other. The floating body (1) is placed at the position.

When the inundated water level is abnormally high and the anchor pole (2) lower end comes out of the pole hole (3), the floating body (1) is tossed by the flow with the anchor pole (2) suspended.

The floating body (1) has a flat plate shape and a very stable structure on the water surface. However, when the anchor pole (2) is suspended, the center of gravity moves downward and the stability is further improved.

Therefore, as long as the pontoon type floating body does not collide with the structure and is damaged and flooded, the building and the human body on the floating body that will not sink will be protected.

[0026] Also, even if the pontoon type floating body (1) is damaged and inundated, the inundation usually takes place after a considerable period of time, and the storm surge flooding often ends by that time!

If the water level is low and the land is flat without any obstacles, the anchor pole (2) is reduced and placed in that position with the floating body (1) left intact.

Next, the construction method of the storm surge levitated building (10) of the present invention at the construction site will be described in detail.

In particular, the conventional floating body (1) is a barge type ship, which has been built at a shipyard that has been equipped with facilities such as large cranes, rails and floating docks.

After completion of inundation, it is always moved or moored on the water, such as offshore towing, and the floating body of the storm surge floating building of the present invention is basically different from that constructed at the construction site and installed at that place for many years.

[0028] Once the construction was completed, the construction site changed one after another, and it was necessary to make a new construction method and change the structure appropriately for how to construct it efficiently on the site without large facilities.

Fig. 2 is a cross-sectional side view of the foundation (4) with the lower right force in Fig. 1 also viewed in the upper left direction. The maintenance passage is shown in Fig. 1. It is.

The foundation is a pool type foundation (7), and the upper surface of the foundation side wall part (15) at both ends protrudes slightly upwards as the ground (9) force so that V flows rainwater. As shown in Fig. 2, a pole hole (3) is drilled in the upper surface inside the pool type foundation to form a pedestal (5) on which the floating body (1) is placed, and a maintenance passage (6 ) Is formed.

[0029] Fig. 3 is a diagram during assembly of the floating body (1). A plate (19) such as a steel plate is laid on the pedestal (5), and the anchor pole (2) and the load platform (11) are connected by welding. Arrange according to the design document.

The load platform (11) is arranged by estimating and designing the required strength in consideration of the load distribution of the building constructed on the floating body and the water pressure when the floating body is submerged. In addition, the bulkhead member (50) in FIG. 4 is provided in the vertical and horizontal directions with a plate material in which a worker's passage is opened in parallel with the side plate material of the carrier type floating body, and prevents the floating body itself from being twisted.

Fig. 6 shows an example of a load table, A is H-shaped steel B is square noise C is a flat plate welded to both ends of a cylindrical pipe D is a combination of four H-shaped steels and both ends are welded to a flat plate. In either case, the force acts in the direction in which the steel plate is compressed vertically so that it has a load bearing strength in the vertical direction.

[0030] The anchor pole (2) itself also functions as a load table that receives a load in the vertical direction.

Floating body in Fig. 3 (1) Assembling work can be performed from the outside of the floating body bottom plate (17) and surface treatment work such as welding and painting from the outside of the side1 because there is no work space, so other than the deck (28) on the top surface of the floating body All work from the inside of the floating body.

Fig. 7 is a side view of the left front force of Fig. 1 as viewed from the right rear side, and is a cross-sectional view of the anchor pole (2) position. Fig. 8 is a cross-sectional view of the pool-type base bottom section AA line. .

FIG. 4 is a completed drawing of the floating body, and the jack lift (8) is arranged in the maintenance passage (6). The jack lift (8) is the opening (12) shown in FIGS. It is carried into the force pool type foundation (7), and the necessary number of units suitable for the weight of the floating body is properly arranged as shown in Fig. 8.

Figure 5 shows the situation where all the jacklifts (8) are operated in synchronism and the entire floating body is lifted, and the anchor pole (2) extends downward due to gravity. In this state, the welding state from the outside of the floating body bottom plate (17) and the side surface, that is, inspection of the welding back wave, surface blasting work such as sand blasting and painting, etc. will be performed.

[0032] Since the portion where the jack lift (8) is in contact with the floating body bottom plate (17) cannot be directly operated, it is supported by the jack lift (8) at the adjacent location and the portion is lowered slightly. As shown in Fig. 7 to Fig. 8, if the difference between the height when the jack lift (8) is reduced and the height when it is extended, that is, if the lift is small and does not reach a sufficient height at one time, use the platform (32). Raise in multiple stages. The gantry shown in Fig. 8 is largely deformed for explanation.

That is, deposit the load on the adjacent jack lift, lower it slightly and place the gantry (32) on top to raise it.

Next, the lifting work is completed when the jack lifts are all lowered in synchronism, the floating body is placed on the pedestal (5), and the jack lift is taken out.

The processing process from the outside of the bottom surface of the floating body can be freely surface-treated such as painting by lifting the entire floating body with a large crane at a shipyard.

In the present invention, a jack lift is inserted into the maintenance passage and the floating body is jacked up downward. This is achieved by moving up and down several dozen or hundreds of jack lifts in synchronization. Even a large giant floating body can be processed.

[0034] FIG. 9 shows a situation where a building is built on a floating body, and the base (35) of the building such as the building (20) and the floating body (1) are firmly connected by an anchor vault (not shown).

An opening / closing door (21) is provided at the right end opening (12) in FIG. 9, and is configured to be opened and closed by a drive device (22) manually or by power.

As shown in FIGS. 7 and 8, the opening (12) of the open / close door (21) opens wide in the width direction, and receives the inundation information such as a tsunami to rotate and release upward.

Figure 10 shows the situation, and the inundation first hits the door (21) and flows into the bottom surface (18) of the pool base (7), and the maintenance passage becomes the water conduit (16) and quickly enters the entire pool. Submerged and floating body (1) rises due to large buoyancy.

In the figure, as the water surface line (14) rises, the floating body floats and the anchor pole (2) extends vertically downward, and the lower end of the anchor pole comes into contact with the pole hole (3). Due to the anchoring action of the hole (3), the floating body is not swept away and maintains its position. When the water level drops, the anchor pole (2) shortens at the same position as the floating body and the building (20), and rests on the original pedestal.

[0036] When the water level rises abnormally high and the lower end of the anchor pole (2) comes out of the pole hole (3), the anchoring action is lost and the building and the floating body are tossed by the flow. As explained in Figure 1.

It is necessary to inspect and maintain the floating bottom plate (17) and the inside of the pool-type foundation (7) once every 10 to several decades. At that time, as shown in Fig. 9, the door (21) is opened and the jack lift ( 8) is carried into the maintenance passage (6), and the maintenance is maintained by jacking up the floating body and all the buildings above it.

The building shown in Fig. 9 is assumed to be a wooden building, and the wooden building has high humidity as in Japan, and is often plagued by white ant damage in the area. There is no room for white ants to enter the building that is built on the body.

[0037] The embodiment of the storm surge building (10) shown in Figs. 11 to 13 is assumed for emergency evacuation used for tsunami evacuation.

This foundation (4) is not a pool type, but the pedestal (5) is exposed on the ground (9), so the floating body (1) deck (28) must rise up the hoistway (25) such as stairs. Nah ...

Fig. 11 is a side cross-sectional view as seen from the side, with the bow of the floating body facing the storm surge from the right side, Fig. 12 is a plan view, and Fig. 13 is a side cross-sectional view from the front. It is.

[0038] The anchor pole (2) is not a telescopic type, but a steel pipe pipe inserted and communicated in a sheath member (23) integral with the floating body (1). When a stagger (26) is provided at the upper end, the floating body rises to some extent. The sheath member (23) abuts on the upper end and acts to pull out the anchor pole (2).

Below the four sides of the floating body is a rainwater cover (13) that is integrated with the floating body (1) so as to cover the ridge (29) on the upper surface of the foundation. Inflow is prevented.

Maintenance passage (6) An open / close door (21) is provided above the right end, and the swing is released in response to storm surge information such as a tsunami. The sea surface is introduced to the bottom of the floating body to promote floating. [0039] In addition, the open / close door (21) is constructed with three or more jack lifts (8) as in the previous embodiment by introducing a jack lift (8) as shown in Figs. ) Synchronize and jack up the floating body.

The size of the maintenance passage (6) is preferably a size that can be inserted by a person, but it may be configured so that it is pushed in and out by using a jig even if a worker does not enter it.

[0040] The left figure in Fig. 14 is an enlarged view of the anchor pole (2) in the lane line A in Fig. 11, and shows the situation where the floating body receives a force that flows to the left as indicated by the arrow as indicated by the arrow. . The right inner wall of the sheath member (23) integrated with the floating body presses the right side surface of the anchor pole, and the left side surface of the lower end of the anchor pole presses the left inner wall of the pole hole.

In this situation, the floating body is anchored by the foundation with the pole hole (3) drilled, and will not be swept away by the flowing water, but will rise due to high buoyancy due to rising water level.

Normally, the gravity of the anchor pole and the friction force of the anchor pole and the pole hole are larger than the friction force of the sheath member and the anchor pole, and the sheath member slides and slides with the anchor pole, and the sheath member integrated with the floating body rises. To do.

Taking into account corrosion due to aging of steel, the tolerance between the outer diameter of the anchor pole and the inner diameter of the sheath member is set to a very large so-called stupid hole.

[0041] However, due to dimensional errors in manufacturing, the sliding resistance between the anchor pole (2) and the sheath member (23) is large, and the anchor pole and the sheath member are fixed, and the floating body (1) has a large buoyancy. The anchor pole may be pulled out of the pole hole (3) before reaching the upper end stopper (26).

The right figure in Fig. 14 shows a partial change in the structure of the sheath member (23) so that the upper and lower two force station anchor poles are sandwiched by the roller wheels (36) that can be rotated from the left and right within the sheath member to reduce the sliding resistance. It is composed.

The roller wheel (36) has a drum shape when the anchor pole is a round steel pipe, and a cylindrical roller when the anchor pole is a square noise.

The jack lift (8) and the gantry (32) used in the present invention will be described in detail with reference to FIG.

Fig. 15A shows a multistage telescopic hydraulic jack (38) that is housed in a container-type trolley (39), with two free wheels (40) on the left and two fixed wheels (41 on the left and right). ) It moves in the maintenance passage with the structure supported by the screw (37) as shown in the figure.

Fig. B shows a state where the hydraulic jack is extended at a predetermined position and the floating body is lifted and loaded via the frame. When the load from above is applied, the push panel squeezes and shrinks, the bottom of the carriage hits the bottom surface of the maintenance passage, and the bottom surface of the maintenance passage supports the floating body of the upper load.

If the hydraulic jack is reduced, it will return to its original state, and the bottom of the carriage will rise, allowing the carriage to move.

[0043] FIG. 15C shows the same structure as the lift of the cross-type frame, and shows a contracted state. FIG. D shows its extended state and is used as a frame.

Similar to the jack lift, the wheel moves in the maintenance passage with the cart (39) structure. The actuator (43) in Fig. D adjusts the height of the gantry with a hydraulic or mechanical telescopic power cylinder.

[0044] Fig. 16 to Fig. 17 describe in detail an example of construction in a building district adjacent to a city area.

Figure 16 is a cross-sectional side view of the front as seen from the road side. The left side is an adjacent building (33), which is closely built and narrower than the flat area of the building (20), and has a pool type foundation (7). I can't apply force.

The building is a reinforced concrete building with a considerable weight, and the floating body depth (D) is increased in order to obtain the buoyancy of the floating body (1) according to the weight.

Between the building foundation (35) and the upper surface of the foundation, a caulking material (30) made of waterproof material is filled to prevent rainwater from flowing into the pool type foundation.

[0045] The upper diagram of FIG. 17 is a side sectional view of the right side facing the road, the central diagram is a plan view taken along the AA section line of the upper diagram, and the lower diagram is a plan view taken along the BB sectional line.

In addition, the vertical cross-sectional position in the upper figure is the one cut along the CC cross-sectional line in the central figure. There is a doorway (31) that can be opened and closed freely in the building, and a communication hole (44) that communicates with it and penetrates the floating body in a watertight downward direction. Connected to the aisle (6).

At the time of floating body construction and maintenance, insert a jack lift from this communication hole (53) and jack up the floating body and the building. [0046] The open / close door (21) at the right end of the upper part of FIG. 17 is the only opening for introducing water into the pool type foundation, and is opened quickly according to the information on the danger of storm surge inundation.

The storm surge inundation flows through the flow channel (34), the lower maintenance channel (6) and the diversion channel (16), and the water is diverted to the left and right as indicated by the arrows in the center, and passes between the floating body and the pool-type foundation side wall (15). It fills the whole and gives buoyancy to the floating body (1), and the floating body rises.

The open / close door (21) is configured to open wide and wide as shown in the central and lower figures in order to allow water to quickly flow into the pool-type foundation.

[0047] As the opening / closing mechanism, a swing type valve, a gate valve, and an air bag type that presses compressed air into a balloon processed with a rubber plate or a hydraulic pressure valve that presses liquid can be used.

The open / close door is configured to be opened and closed manually or by a powered actuator (43). During normal times, it is always closed for many years to prevent the inflow of rainwater and to open quickly in response to storm surge information.

Maintenance of the open / close door (21) and the actuator (43) allows workers to go down to the maintenance passage (6) from the entrance / exit (31) in the building via the communication hole and perform various inspections and maintenance work on the inside force. .

18 to 25, a method for manufacturing a reinforced concrete floating body in which a buoyant mold member (45) having a large buoyancy is encapsulated in the floating body will be described in detail.

Figure 18 shows a pool-type foundation (7) that is built and built mostly underground.

Figure 19 shows the situation where the formwork (46) is assembled and arranged on the base (5) according to the outer diameter of the floating body according to the production drawing, and the anchor pole and buoyancy mold (45) are installed. The buoyancy mold (45) is a box formed by molding polystyrene foam or wooden formwork into a hollow rectangular parallelepiped, and is a buoyancy body for reducing the apparent specific gravity of the float (1).

Fig. 20 shows the situation in which reinforcing bars (47) are formed in the formwork (46) and the buoyancy mold (45) is installed, and in particular, the buoyancy mold (45) has a higher specific gravity than water when pouring concrete, which will be described later. In order to suppress the levitation, the reinforcing bars (47) in the vertical direction and on the upper surface of the floating body are placed to give strength.

The upper diagram of FIG. 21 shows a state in which the formwork (46) and the buoyancy mold (45) and the reinforcing bar (47) are arranged, and the AA cross section is shown in the center view and the BB cross section is shown in the lower view in plan view.

As shown in the center figure, the four buoyancy molds (45) in the center of the floating body are deformed into a flat L shape, A communication hole (44) penetrating in the central vertical direction is formed. As shown in the figure below, the jack lift (8) is lowered onto the maintenance passage through the communication hole and disposed at an appropriate position.

Fig. 22 shows the state of injection of the raw concrete (48). Although not shown, the upper left force is also press-fitted through the hose (49) by the concrete pump car so that no cavities or bubbles can enter! / Then, press-fit while observing the fluid state.

In addition, buoyancy-type materials receive large buoyancy from ready-mixed concrete, so ready-mixed concrete must be filled in stages while taking into account its degree of hardening so as not to destroy the reinforcing bar arrangement.

[0050] FIG. 23 shows a state in which the above-described ready-mixed concrete press-in work is completed. When a predetermined concrete hardening time elapses, the communication hole (44) force in the upper part of the floating body also lowers and introduces the jack lift. Figure 24 shows the situation of the work of removing the formwork (46) by raising the jack lift synchronously. After ascending, lower the adjacent jack lift (8) slightly to remove the part of the formwork, then raise the jacklift to deposit the load and lower the others to remove the formwork.

Fig. 25 shows the situation where all the molds are removed and the jack lift (8) is lowered synchronously, the floating body (1) manufacturing process is completed, and the jack lift is lifted to the upper part of the floating hole (44). Although not shown, an anchor vault is projected on the upper surface of the reinforced concrete floating body, and a building base is connected to the anchor vault.

This concrete floating body is more advantageous in maintenance than the floating body made of steel plate because there is no corrosion due to secular change.

With reference to FIG. 26, an example of a general private house will be described with a bird's eye view.

This figure will be understood and understood if the upper figure and the building are written in the figure below, so they are shown separately, and the upper figure (1) is located inside the lower pool type foundation (7) as shown by the arrow. Indicates the status of storage.

The size of the inner wall of the pool base (15) where the floating body is stored is slightly larger than that of the floating body, and is used to protect the floating side steel plate made of hard rubber such as fenders used when mooring ships. Inserted with the gap member (52) in between, the floating body is placed on the pool-type foundation pedestal (5).

Opening at the right end of the foundation (12) force during flood flooding The inside of the base is filled with buoyancy, and the floating body rises.

[0052] The pool-type foundation side wall portion (15) erected vertically above the four sides of the floating body is the guide wall

(51), and is always in light contact with the floating body side surface via the gap member (52), and the floating body floats vertically upward by preventing horizontal movement of the floating body side surface by running water.

The anchor device by the guide wall (51) through the floating body side surface and the gap member has a simpler structure and a stronger anchor action than the anchor device by the anchor pole and the pole hole, and can be manufactured at a lower cost.

However, the anchor action is only while the floating body side surface comes into contact with the guide wall. If the flooded surface is high and the floating body surface rises above the height of the guide wall, the anchor action will be lost and the water will be overwhelmed.

[0053] Although not shown, an anchor device having an ideal anchor action can be manufactured by using the anchor device by contact between the guide wall and the floating body side surface and the anchor device by the anchor pole and the pole hole.

In other words, the first wave of the tsunami has many high-speed shock waves, but at that time, the floating body is prevented from moving horizontally by the strong anchoring action of the floating body and the guide wall, the flooded water surface becomes higher and the flow velocity decreases, and the anchor pole and pole hole The floating body flow can be prevented by the anchor action. The gap member facilitates the contact between the floating body side surface, which is not always necessary, and the pool side wall as a concrete guide wall. If there is storm surge flooding, it can be repaired at that time.

FIG. 27 shows an embodiment of a high-rise building having a large area floating body (1) and a large number of anchor poles (2).

The pool base is provided with a rectangular parallelepiped base and a maintenance passage where the jack lift can move. The bottom of the maintenance passage is directed toward the drainage pit (53) indicated by the dotted line provided below the opening (12). There is a downward water gradient as shown by the gradient arrow (54).

-And if storm surge inundation occurs and it is immersed in the pool, it will take a very long time for the bottom of the pool to dry horizontally.

Although not shown in the figure, the opening (12) at the right end of the pool type foundation is provided with a normally closed door, which opens by storm surge inundation information. Also, the opening guides the jack lift during maintenance such as floating bodies. At the same time, the water in the pool is drained into the drainage pit (53) through the drainage pump and hose.
