As a countermeasure in that case, for example, by installing a protection pillar on the dike and stretching wires or meshes between the protection pillars, it is possible to capture ships and prevent further flow into the land. Yes.
However, since such conventional protective devices are generally of a constant height, there is a problem that if a tsunami with a height exceeding the expected level is reached, it can easily be exceeded and cause serious damage. Then, it is sufficient to make the protective device higher than the beginning, but doing so has the disadvantage of detracting from aesthetics.

  The present invention is intended to solve such a problem, and even when a tsunami exceeding the expected level can be obtained, it is possible to capture a ship or a container that is washed away, and at low times during normal times, so as not to damage the environment. An object of the present invention is to provide an emergency protective device capable of

In order to achieve the above-mentioned object, the present invention according to claim 1 is configured such that a plurality of bases are fixedly disposed on an installation base where a tsunami current is expected to come in, so as to be spaced apart from each other. Stands in a state where it falls to the front side where the tsunami current flows, while a self-levitating protective column that can be raised and lowered by the tsunami current supports the base with a hinge shaft Each protection column is provided with a main float at its tip with a levitation-promoting surface that allows the protection column to stand up in response to a tsunami flow in a state where the protection column has fallen forward. These protective pillars are stretched so that the wire rope that can catch drifting objects extends in multiple stages, and the uppermost wire rope is attached with a wire float to stop the protective pillar from rising. As a member, one end is fixed at a position corresponding to the front side where the tsunami flow flows from the base position on the installation base, and the other end is fixed at a position corresponding to between the protection columns of the wire rope. A retaining member is provided that is inclined upward from the one end to the other end when it gets up .

As described above, according to the present invention , a plurality of bases are fixedly arranged so as to be separated from each other on an installation base where a tsunami current is expected to come, and each of these bases is a side on which a tsunami current flows. A protective column with a self-levitation that can be raised and lowered so as to get up while rising by a tsunami current is provided with its base supported by a hinge shaft, while standing in a state of falling toward the front side. A main float with a levitation-promoting surface is installed at the tip of the column so that the column can be raised in response to a tsunami flow when the column is tilted forward. A wire rope is attached to the uppermost wire rope and a wire float is attached to the uppermost wire rope. It is fixed at a position corresponding to the front side where the tsunami flow flows from the base position, and the other end is stopped at a position corresponding to between the protective poles of the wire rope. It is characterized by the fact that it is provided with a retaining member that rises diagonally toward the surface, so that even if a tsunami that exceeds the expected level can be captured, it can catch ships and containers that are washed away, and it is low during normal times and does not damage the environment An emergency protection device can be provided.

  The front view which shows one Embodiment of this invention.   AA sectional view taken on the line AA of FIG.   The side view which shows other embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
1 and 2 show another embodiment. When the tsunami stream X hits, fishing boats, cargo containers, coastal vehicles 25, building debris and other things are washed away to the land. In addition, if such ships attack a coastal power plant or oil tank, it will cause a major disaster. Therefore, if the flow of these various things is not stopped in a certain place, it will be further washed away and it will become a factor which destroys other houses and various facilities.

  FIG. 1 and FIG. 2 are made in order to solve such a problem, and 26 is an installation base, which may be any of the ground, the concrete surface, and the plate surface. The base 26 is provided with an emergency protective device that stands up against the assumed flow direction of the tsunami X. In this apparatus, a base 31 provided with a pair of receiving plates 28 on a seat 27 and through which a hinge shaft 29 is passed and a rising stopper 30 on the back is fixed and arranged at intervals of 10 to 30 m by a fixing tool 32. It is.

  The base 31 is provided with a protective pillar 33 made of a tsunami-flowing material such as a metal pipe, a large-diameter wood material, or a resin that can be raised and lowered. A main float 34 is attached to the upper end of each protection column 33. The float 34 has a sloped levitation promoting surface 34a at the tip thereof and is pushed up by the action of the tsunami flow X instead of simply floating. It has become. The float 34 is hollow or made of a floating material. The main float 34 may be omitted when the protective column 33 itself is, for example, a wide type and can secure a strong flying performance.

  Through the protective pillars 33, through-wire wire ropes 35 are passed over several stages. An appropriate number of wire floats 36 are provided on the wire rope 35, and a retaining wire 37 is stretched between the wire rope 35 and the base 26. The retaining wire 37 is in a relaxed state in the state of an imaginary line, and is pulled when the protective column 33 rises, and keeps the protective column 33 up with the stopper 30. Reference numeral 38 denotes a wire fixing tool, and an anchor pile 39 may be used as shown in the lower column. The retaining wire 37 and the stopper 30 may be configured with either one.

Before the tsunami flow X strikes, the protective column 33 is in a forward-turned state as shown by the phantom line in FIG. 2. When the tsunami flow X comes there, the rising force acts on the levitation promoting surface 34a and the protective column 33 When the buoyancy acts on the main float 34, the wire float 36, and the like, the protective pillars 33 with wire ropes stand up together and are kept upright by the retaining wire 37 and the stopper 30.
Thereby, even if a ship, vehicles 25, etc. are washed away with the tsunami flow X as shown in the figure, they can be received and prevented from flowing further into the back ground. The stopper wire 37 has a buffering action together with the wire rope 35 by omitting the stopper 30 or using an elastic member, or by setting the stopper wire 37 so as to function as a stopper for the first time after the tension wire 37 is stretched. The effect of catching the vehicle 25 and the like is exhibited, and there is an effect that the damage of the vehicle 25 and the like is reduced and the wire rope 35 is prevented from being exceeded, and further the damage of the wire rope 35 and the like is reduced. The retaining wire 37 may be a link chain, a rope, or a link-like member. The wire rope 35 may be stretched with a mesh.

FIG. 3 shows another embodiment. This embodiment has the same purpose as described above, but also has the purpose of making it possible to counter the case where a pulling wave Y strikes. That is, 42 is an installation base, 43 is a base, 44 is a hinge shaft, 45 is a stopper, 46 is a protective column made of a floatable pipe, 47 is a bent plate-like floating promotion piece, 48 is a wire rope, 49 is a retaining Indicating a wire, such a protective device is provided with a reversing stopper 50. The reversing stopper 50 has a base rotatably attached to the wire rope 48 or the protective column 46, and has a free end. In normal times, the reversing stopper 50 extends horizontally like a virtual line. When X acts, it is lifted along with the protection column 46 that rises, and its tip engages in an engagement recess 51 formed in the base 42. As a result, the reversing stopper 50 becomes a support rod of the protective column 46 and keeps the protective column 46 in an upright state even when the pulling wave Y acts. Can be prevented from flowing further into the sea. The engaging recess 51 can also be provided by providing a protrusion on the installation base 42.
As shown in the right column diagram, the reversing stopper 50 may be of a type in which the tip pierces the installation base 42. As shown in the figure, the guard column 46 is difficult to exceed if it stays in a forward-tilted state so as to hold something that flows in.
