前記防潮堤は所定の高さの堤体を有し、該堤体の下端部に人又は車の通行するゲート用開口を設け、かつ、越流した海水を放出する放水用開口を該堤体の上下方向に複数個を設け、該ゲート用開口及び放水用開口に遠隔操作による開閉可能な扉体及び該扉体を制御する制御装置を設け、操作指令により該ゲート用開口及び該放水用開口の開閉を制御可能にしたことを特徴とする。
The invention according to claim 1 is an alarm means for reporting evacuation routes, shelters and tsunami attacks to protect the lives of residents living in coastal areas against tsunami attacks, In the tsunami disaster prevention system that has a seawall to protect property and life such as
The tide embankment has a levee body having a predetermined height, a gate opening through which a person or a vehicle passes is provided at the lower end of the levee body, and a water discharge opening for discharging overflowed seawater is provided in the levee body. The gate opening and the water discharge opening are provided with a door body that can be opened and closed by remote operation and a control device for controlling the door body, and the gate opening and the water discharge opening according to an operation command. It is possible to control the opening and closing of the.

請求項４の発明は、請求項１〜請求項３の発明において、前記防潮堤は前記堤体の天端部の上面に歩道または車道を設け、該天端部の両縁部に人または車の落下を防止するための防止柵を設け、該落下防止柵は該堤体の天端高さを超える津波の来襲時には海側域で浮遊して漂流する漂流物が陸側域内へ流入するのを防止し、津波の引き波時には陸側域内で浮遊して漂流する漂流物や人間が漂流して海側域に流出するのを防止するように構成したことを特徴とする。
According to a fourth aspect of the present invention, in the first to third aspects of the invention, the tide embankment is provided with a sidewalk or a roadway on the top surface of the top end of the levee body, and a person or a vehicle is provided on both edges of the top end. Fences that float and drift in the sea side area will flow into the land side area when a tsunami that exceeds the crest height of the levee body is provided. It is configured to prevent drifting objects and people drifting and drifting in the land side area and drifting out to the sea side area at the time of tsunami pulling.

請求項５の発明は、請求項１〜請求項４の発明において、前記防潮堤の海側域及び陸側域に存在し、津波によって漂流物となる可能性のある車両等を漂流しないようにする漂流防止手段を具備し、該車両の漂流防止手段は、駐車場に駐車している車両が津波水により浮上して漂流しないように、津波水の来襲する正面及びその両側に堅固な壁体を設け、該壁体に弾性体からなる屋根を低い位置に設けたことを特徴とする。
Invention of Claim 5 exists in the sea side area and land side area of the said tide embankment in invention of Claim 1-4, so that it may not drift a vehicle etc. which may become a drifting object by a tsunami. The drift prevention means of the vehicle has a rigid wall body on the front and both sides where the tsunami water comes to prevent the vehicle parked in the parking lot from floating due to the tsunami water. And a roof made of an elastic body is provided at a low position on the wall body.

請求項１〜請求項３の発明によれば、津波の引き波後に越流した海水の放水速度を制御することにより、住居等の建物類の崩壊、流失を防止することができるという効果が得られる。この結果、住民は安心して避難できるという効果が得られる。また、請求項２、請求項３の発明によれば、津波高さが防潮堤を越えない場合には津波による被害から完全に守られるという効果が得られ、津波高さが防潮堤を越える場合であっても避難することにより住民の生命だけは守られるという効果が得られる。
According to the first to third aspects of the invention, by controlling the discharge rate of the seawater that has overflowed after the tsunami has been pulled, the effect of preventing the collapse and loss of buildings such as residences can be obtained. It is done. As a result, residents can evacuate with peace of mind. Further, according to the inventions of claims 2 and 3, when the tsunami height does not exceed the seawall, the effect of being completely protected from damage caused by the tsunami is obtained, and when the tsunami height exceeds the seawall. Even so, evacuation can protect the lives of residents.

請求項４の発明によれば、天端高さを超える津波の来襲時には海側域で浮遊して漂流する漂流物が陸側域内へ流入するのを防止し、津波の引き波時には陸側域内で浮遊して漂流する漂流物や人間が漂流して海側域に流出するのを防止して、津波による被害を軽減する効果を有すると共に、防潮堤の本来の機能の他に観光用としての効果も有する。また、請求項５の発明によれば、自動車等の発火しやすい漂流物を浮上させないように固定することにより被害を軽減するという効果が得られる。 According to the invention of claim 4, in the event of a tsunami that exceeds the height of the top, the drifting object that floats and drifts in the sea side area is prevented from flowing into the land side area. It has the effect of reducing the damage caused by tsunami by preventing drifting drifting people and people drifting and drifting out to the sea side area, as well as the original function of the seawall, as well as for tourism It also has an effect. Further, according to the invention of claim 5, the effect of reducing damage can be obtained by fixing the drifting substance that easily ignites such as an automobile so as not to float.
