2. Description of the Related Art Conventionally, flood control measures against flood damage include site defense that covers the entire site where the building or facility is built, building defense that uses the outer wall of the building or facility to protect only that building or facility, Or, there are three ways of thinking about defense of important rooms, in which only important rooms in a building or facility are sectioned and protected.
These are used alone or in combination. The flood control equipment used for these flood control measures forms the backbone to prevent flooding of the defense area, and the design water level is in the middle of the height of the openings, windows, and site boundaries that are always open during normal times. It will be installed at the entrance and exit of the defense section, etc.

As a light water protection equipment, a water protection plate made of aluminum is used. Normally, the water protection plate is stored in a nearby storage place, and when it is abnormal, it is taken out and installed in a water protection plate groove or a mounting tool. Although there are some that are designed to prevent water from entering, generally, a water shield that is divided into a size and weight that can be carried and installed by one or two people is used, and this water shield is installed at a specified position. There are many types that can be tightened with a lever handle, etc. after being built in, and there are sliding door type, opening type, assembling type, as well as methods such as a rising type that is embedded in the floor and raised when used. Also has the trouble of having to move it by human power and set it, and this involves the problem that in an emergency an inoperable situation may occur. On the other hand, some of them detect flooding and automatically activate necessary water-proof equipment electrically or hydraulically, which naturally increases safety, but on the other hand, it causes problems of complexity and economy.

[0005]

In order to solve the above-mentioned problems, the water-proof equipment according to the present invention is always stored and provided with a water-proof plate which is installed so as to prevent water from flooding a defense section in the event of an abnormality. In the water defense equipment, a storage recess is provided on the floor surface of the defense compartment entrance and exit, and a water shield plate that has buoyancy against the water that floods the defense compartment far is always stored in the storage recess. It is characterized in that it is installed so as to float from the inside of the storage recessed portion to the inundation prevention position by the buoyancy of the water to be inundated.

Further, in the water-proof equipment according to the present invention, the water-proof plate is integrally formed by combining a buoyant material having buoyancy with respect to water and a structural material against the water pressure of the water to be flooded. The buoyant material and the fluid are made hollow and the skeleton that resists the fluid pressure is integrated, and the levitation force of the fluid flowing into the periphery of the skeleton causes the material and the fluid to float up from the storage location and be erected. A structure that is integrated with a framework that resists pressure and is floated and erected by the action of the buoyant pressure of the fluid that flows into the periphery of the framework. It is lifted from the storage location and erected by the action of pressure. Further, the water-proof equipment according to the present invention is characterized in that the water-proof board is provided with a protective material for supporting the weight at a portion facing the floor surface of the defense section entrance when the water-proof board is stored and for preventing the water-proof board from being worn or damaged. It is what

According to the water defense system of the present invention, when water enters the defense compartment due to the occurrence of an abnormal situation, the water first enters the storage recess provided on the floor of the defense bay entrance of the water defense facility. , Since the buoyancy force is exerted on the water blocking plate that is stored and installed in the storage recess, this causes the water blocking plate to float by itself from the storage recess to the intrusion prevention position, and dams the water that tries to enter the defense compartment. .

Further, since the water blocking plate is integrally formed not only with the buoyancy member but also with the structural member, it can sufficiently counter the water pressure of the water to be infiltrated and prevent the infiltration of water. . In addition, people and vehicles pass over the waterproof plate because it is open at all times, but the surface of the waterproof plate is equipped with a protective material to prevent the wear and damage of the waterproof plate. The plate can be protected for a long time.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing a water defense facility according to a first example of the present invention, FIG. 2 is a perspective view showing its operating state, and FIG.
Is a partially cutaway perspective view showing the structure of the waterproof plate used for it.
FIG. 4 is a cross-sectional perspective view showing the configuration of the storage recess of the waterproof plate,
FIG. 5 is a perspective view showing an operating state of the water defense equipment according to the second example of the present invention, and FIG. 6 is a partially enlarged perspective view thereof.

The first example is an example in which a water-proof facility for preventing inundation at the time of water damage is installed at the entrance / exit 2 of a concrete structure 1 that forms a defense section such as a fence or a wall of a building provided at the boundary of the site. Show. On the floor surface 3 of the entrance / exit 2, a groove-shaped storage recess 5 is dug down to a set depth over the entire width of the entrance / exit 2 in order to store the water blocking plate 4. The storage recess 5 is provided so that invading water can enter, and is constructed by covering both side surfaces and the bottom surface with concrete 6 as shown in FIG.

On both side walls of the entrance / exit 2 of the concrete structure 1, in order to guide the floating due to the buoyancy of the water blocking plate 4, guide rails 7 made of channel type steel extending upward along both ends of the storage recess 5 are provided. Is installed, and a stopper 8 for stopping the floating of the water blocking plate 4 at an appropriate position is provided on the upper part thereof. The guide rail 7 is provided with a slide bearing 9 such as a sphere or a roll bearing as shown in FIG. 3 in order to smoothly guide the floating of the waterproof plate 4.

On the other hand, the water-proof plate 4 is generally reinforced as shown in FIG. 3, such as a buoyant material 10 having a large buoyancy such as Styrofoam and expanded polystyrene, and a metal-based, wood-based, concrete-based framework framed to resist water pressure It is integrally formed in a panel shape by combining it with a structural material 11 used as a material, and is configured to have buoyancy with respect to water so that it can float when water enters the storage recess 5. It is installed in the storage recess 5.

The water-proof plate 4 needs to be constructed so as to have buoyancy with respect to water, and in particular, it is desirable to use a material such as lightweight concrete which itself has buoyancy and can also serve as a structural material and a protective material. The deck plates 12 and the like are attached to both side surfaces as necessary. A protective material 13 is provided on the top surface of the water blocking plate 4 facing the floor surface 3 to support the weight of people, vehicles, etc. passing therethrough and prevent the water blocking plate 4 from being worn or damaged. The water-proof plate 4 may be provided with an adjusting valve so that the buoyancy can be adjusted by pre-sealing water or other heavy objects.

However, according to the above example, when the water W enters the defense section due to abnormal tide, flood, or other water damage, the water W enters the entrance / exit 2 of the concrete structure 1 forming the defense section. Storage recess 5 provided on the floor 3
And then exerts buoyancy on the water blocking plate 4 installed in the storage recess 5. As a result, the water blocking plate 4 floats from the inside of the storage recess 5 by itself, rises above the floor surface 3 along the guide rail 7 as shown in FIG. 2, and can block the water W that is about to enter.

Therefore, it is possible to eliminate the hassle of having to carry out the water blocking plate 4 from the storage location or to move and set the water blocking plate 4 from the built-in position by the force of a person when an abnormality occurs due to water damage, and to make an emergency. It is possible to provide a water protection facility that automatically operates by itself even when a person cannot sometimes operate it. Also,
Since such a water proof equipment can be realized with a simple structure in which the water proof plate 4 has a structure having buoyancy, it is possible to provide an economical water proof equipment that can be installed at a low cost.

Further, the water blocking plate 4 is not limited to the buoyancy member 10,
Since it is formed integrally with the structural material 11,
Sufficiently counters the water pressure of the water W that is about to enter,
In addition to being able to prevent inundation, people and vehicles pass over the water blocking plate 4 because it is always open as the doorway 2. However, the surface of the water blocking plate 4 supports the weight of the water blocking plate 4.
Since the protective material 13 for preventing abrasion and damage is provided, the waterproof plate 4 can be protected and used for a long period of time.

Next, a second example will be described with reference to FIGS. The second example is a relatively shallow and wide storage recess 5 on the floor 3.
A is provided, and a water proof plate 4A having one end coupled to the floor surface 3 via a hinge 14 is stored and installed in the storage recess 5A,
The water blocking plate 4A is integrally formed by combining the buoyancy member 10 and the structural member 11, and the free end side of the water blocking plate 4A is lifted in the direction of the arrow shown by the buoyancy force against the water W entering the defense compartment. The water W that rises and tries to enter can be stopped. Therefore, it is possible to expect the same effects as those of the first example described above.

[0018]

As described above, according to the water defense equipment of the present invention, a storage recess is provided on the floor surface of the entrance and exit of the defense compartment, and the buoyancy of the water entering the storage recess causes it to float by itself. Since a water blocking plate is installed to stop the water that is trying to enter, it is necessary to take out the water blocking plate from the storage location or move it from the built-in position by human power each time an abnormality occurs. Can be eliminated. In addition, even when a person cannot operate in an emergency, it operates automatically by itself, so that it can function reliably and a simple structure in which the waterproof plate has a structure with buoyancy. Therefore, it is possible to economically install flood control equipment at low cost. Furthermore, since the waterproof plate is integrally formed by combining the buoyancy material and the structural material, it can sufficiently resist the water pressure of the water that is trying to infiltrate, and the protective material is applied to the part of the waterproof plate facing the floor surface. Since the water-proof plate is provided, it is possible to support the weight of the vehicle or the like, prevent the water-proof plate from being worn or damaged, and protect and use the water-proof plate for a long period of time.
