Description

本発明は、外部から所定領域内に水が浸水することを防止する浸水防止構造に関し、特に浸水の危険がある場合に自動的に防水板が起立する浸水防止構造に関する。   The present invention relates to a flood prevention structure that prevents water from entering a predetermined area from the outside, and more particularly to a flood prevention structure in which a waterproof plate is automatically erected when there is a danger of flooding.

従来よりゲリラ豪雨や洪水のときに敷地内や建築構造物内などの所定領域内に水が浸水することを防ぐために、例えば出入り口などの水が浸水できる経路上に、防水板を設置して水の浸水を防ぐ技術が種々提案されている（例えば特許文献１、特許文献２）。このような防水板は、浸水のおそれがない日常には通行の妨げにならず、非常時にはすぐに設置する必要がある。そこで、地面に収納溝を設け、この溝内に防水板を収納しておくことで日常の通行の妨げにならないようにしておき、非常時には手動又は電動で簡単に起立させることができる構成が採用されている。   Conventionally, in order to prevent water from entering a predetermined area such as a site or a building structure in the event of heavy rain or flooding of guerrillas, water is installed by installing a waterproof plate on the path where water can be submerged, such as doorways. Various techniques for preventing water infiltration have been proposed (for example, Patent Document 1 and Patent Document 2). Such a waterproof plate does not hinder traffic in daily life when there is no risk of flooding, and must be installed immediately in an emergency. Therefore, a storage groove is provided in the ground, and a waterproof plate is stored in the groove so that it does not interfere with daily traffic, and in an emergency, it can be easily raised manually or electrically. Has been.

しかし、手動で防水板を起立させる場合、人が管理し人が判断して防水板を起立させることになるので、時間帯などによっては迅速な対応が困難であり、人為的なミスが発生する可能性もある。また、電動のセンサ等によって判断し、電動で防水板を起立させる場合には、電気系統の故障により正常に作動しないおそれがある。   However, when standing the waterproof plate manually, the person will manage and judge by the person to make the waterproof plate stand up, so it is difficult to respond quickly depending on the time of day, and human error will occur There is a possibility. Further, when the waterproof board is erected by the electric sensor or the like as determined by an electric sensor or the like, there is a possibility that the electric system does not operate normally due to a failure of the electric system.

そこで、防水板を水に浮くように構成しておき、高さ方向に掘られた収納溝内に外部の水を流入させて貯水し防水板を浮力によって上方にスライドさせて起立させる構造が提案されている（例えば特許文献３）。この構成によると、通常の外部から水が導入されることがないときには防水板は収納溝内に止まり、ゲリラ豪雨や洪水などのように外部に水がある場合にのみ防水板が起立するので、必要な時に自動的に防水板を起立させることができる。しかも、単に水を流入させるだけの単純な構成であるので、電気的な制御を必要とせず、極めて故障しにくいものにすることができる。   Therefore, a structure is proposed in which the waterproof board is configured to float on the water, external water flows into the storage groove dug in the height direction, the water is stored, and the waterproof board is slid upward by buoyancy to stand up. (For example, Patent Document 3). According to this configuration, when water is not normally introduced from outside, the waterproof plate stops in the storage groove, and the waterproof plate stands only when there is water outside such as guerrilla heavy rain or flood, The waterproof board can be erected automatically when needed. In addition, since it has a simple configuration that simply allows water to flow in, it does not require electrical control and can be extremely resistant to failure.

ところで、特許文献３のように、防水板を浮力によって上方にスライドさせて起立させる浸水防止構造は、防水板を収納する収納溝を少なくとも防水板の高さ以上に掘り下げる必要があるので、場所によっては設置が困難となる場合もあり、また、より高い防水板が必要な場合には、より深く掘り下げる必要があることから設置コストが増加する問題がある。   By the way, as in Patent Document 3, the inundation prevention structure in which the waterproof plate is slid upward by buoyancy to stand up needs to dig up the storage groove for storing the waterproof plate at least more than the height of the waterproof plate. In some cases, it is difficult to install, and when a higher waterproof board is required, it is necessary to dig deeper.

そこで、本発明は、極めて故障しにくい単純な構成であって、収納溝の深さを抑えることができる浸水防止構造を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a flood prevention structure that has a simple configuration that is extremely resistant to failure and that can suppress the depth of a storage groove.

An inflow passage in which one end communicates with an outlet provided in the bottom surface of the storage tank and the other end communicates with an inlet provided in the storage groove, and a regulating valve that regulates passage of water in the inflow passage It is characterized by providing these.

請求項１に記載の浸水防止構造は、流入防止部により地面から所定高さ以下の水が収納溝に流入することを阻止するので、防水板を起立させる必要がない比較的弱い雨のときには、収納溝に水が流入することがなく、防水板が不必要に起立することを抑制できる。また、防水板は、収納溝内に収納される浮力体を有し、その下端が収納溝の上端に回動可能に固定されており、収納溝内に水が注入されて浮力体に浮力が加わると回動して起立し、外部から所定領域内への水の流入を阻止するものであるので、人による操作や電気的な制御を必要とせず、簡単で故障しにくい構成にすることができる。また、防水板は、地面に向かって伏せた状態で収納溝に収納されることとなるので、収納溝の深さが比較的深くならないので、設置コストを低減することができ、地中に構造物があるような場合も干渉することなく設置することができる。
また、この浸水防止構造は、防水板を回動させて起立させる浸水防止構造であって、防水板が上下方向の中間部に折り曲げ可能な屈曲部を備えており、収納溝に折り重ねられた状態で収納されるので、浸水防止構造の近傍に他の構造物があるなどの理由で、収納溝を設置するスペースが少ない場合にも設置することができる。 The inundation prevention structure according to claim 1 prevents water having a predetermined height or less from flowing into the storage groove from the ground by the inflow prevention portion. Therefore, in the case of relatively weak rain that does not require standing of the waterproof plate, Water does not flow into the storage groove, and the waterproof board can be prevented from standing up unnecessarily. The waterproof plate has a buoyant body stored in the storage groove, and its lower end is rotatably fixed to the upper end of the storage groove. Water is injected into the storage groove so that the buoyancy body has buoyancy. When it is added, it rotates and rises up to prevent the inflow of water from the outside into the predetermined area. it can. In addition, since the waterproof plate is stored in the storage groove in a state of being face down toward the ground, the depth of the storage groove does not become relatively deep, so that the installation cost can be reduced, and the structure in the ground Even when there is an object, it can be installed without interference.
In addition, this water-infiltration prevention structure is a water-invasion prevention structure in which the waterproof plate is turned upright, and the waterproof plate is provided with a bent portion that can be bent in the middle in the vertical direction, and is folded in the storage groove. Since it is stored in a state, it can be installed even when the space for installing the storage groove is small due to other structures in the vicinity of the inundation prevention structure.

請求項２に記載の浸水防止構造は、請求項１と同様に、流入防止部により地面から所定高さ以下の水が収納溝に流入することを阻止するので、防水板を起立させる必要がない比較的弱い雨のときには、収納溝に水が流入することがなく、防水板が不必要に起立することを抑制できる。また、防水板は、収納溝内に収納される浮力体を有し、この収納溝内に水が注入されて浮力体に浮力が加わると上方にスライドして起立し外部から所定領域内への水の流入を阻止するので、人による操作や電気的な制御を必要とせず、簡単で故障しにくい構成にすることができる。また、防水板は、上下方向の中間部に折り曲げ可能な屈曲部を備えており、収納溝に折り重ねられた状態で収納されるので、収納溝に収納する際の防水板の高さを低くすることができ、収納溝の深さが比較的深くならず、設置コストを低減することができ、地中に構造物があるような場合も干渉することなく設置することができる。   Since the inundation preventing structure according to the second aspect prevents the water having a predetermined height or less from flowing into the storage groove from the ground by the inflow preventing portion, similarly to the first aspect, it is not necessary to raise the waterproof plate. When rain is relatively weak, water does not flow into the storage groove, and the waterproof plate can be prevented from standing unnecessarily. Further, the waterproof plate has a buoyancy body stored in the storage groove, and when water is injected into the storage groove and buoyancy is applied to the buoyancy body, the waterproof plate slides upward to stand up from the outside to a predetermined region. Since the inflow of water is prevented, no human operation or electrical control is required, and the configuration can be made simple and resistant to failure. In addition, the waterproof plate has a bendable portion that can be bent at an intermediate portion in the vertical direction, and is stored in a state of being folded in the storage groove, so that the height of the waterproof plate when stored in the storage groove is reduced. The depth of the storage groove is not relatively deep, the installation cost can be reduced, and even when there is a structure in the ground, the storage groove can be installed without interference.

また、請求項１及び請求項２に記載の浸水防止構造は、防水板を展開方向へ付勢する付勢手段を備えているので、防水板が起立したときに屈曲部が展開して、自動的に防水板の高さをかさ上げすることができる。 Further, since the inundation preventing structure according to claim 1 and claim 2 is provided with a biasing means for biasing the waterproof board in the deployment direction, the bent portion is automatically deployed when the waterproof board is erected. Thus, the height of the waterproof plate can be raised.

請求項３に記載の浸水防止構造は、防水板が起立したときに、所定領域側に傾くので、外部から所定領域に向かって勢いのある水流が流れ込もうとしたときに、防水板に水流が衝突して加わる荷重を防水板の傾きにより上方に逃がすことができる。 The inundation preventing structure according to claim 3 is inclined toward the predetermined region when the waterproof plate stands up, so that when a strong water flow flows from the outside toward the predetermined region, The load applied by the collision can be released upward by the inclination of the waterproof plate.

請求項４に記載の浸水防止構造は、防水板が起立したときに、この防水板が略鉛直な状態から所定領域側に所定角度傾いた状態まで揺動可能に形成されており、この防水板が略鉛直となる方向に付勢する付勢部材をさらに備えるので、外部から所定領域に向かって勢いのある水流が流れ込もうとしたときには、防水板にかかる水流の圧力が付勢部材の付勢力に抗して防水板を所定領域側に傾けるので、水流の勢いを弱めることができ、さらに防水板が所定領域側に傾くことにより、この水流の圧力を上方に逃がすことができる。一方、付勢部材の付勢力よりも弱い水流や水圧の場合は、防水板は略鉛直な状態のままであり、防水板の高さが高い状態を維持することができる。 The inundation preventing structure according to claim 4 is formed so as to be swingable from a substantially vertical state to a state inclined at a predetermined angle toward a predetermined region when the waterproof plate stands up. Is further provided with an urging member that urges the urging member in a substantially vertical direction, so that when a strong water flow flows from the outside toward the predetermined area, the pressure of the water flow on the waterproof plate is applied to the urging member. Since the waterproof plate is inclined toward the predetermined region against the force, the force of the water flow can be weakened, and further, the pressure of this water flow can be released upward by the waterproof plate being inclined toward the predetermined region. On the other hand, when the water flow or the water pressure is weaker than the urging force of the urging member, the waterproof plate remains in a substantially vertical state, and the waterproof plate can be maintained at a high height.

請求項５に記載の浸水防止構造は、防水板の所定領域側に堤防が形成されるので、例えば海岸や河岸などの堤防の海又は川側に起立したときの高さが堤防よりも高い浸水防止構造を設置することで、日常は景観を壊すことがなく、水量が増した緊急時にのみ防潮板の役割を果たすことができ、また、堤防の支えにより、極めて強固な浸水防止構造とすることができる。 In the inundation prevention structure according to claim 5 , since the embankment is formed on the predetermined region side of the waterproof plate, for example, the inundation is higher when standing on the sea or river side of the embankment such as the coast or the riverbank. By installing a prevention structure, the landscape will not be destroyed on a daily basis, and it can play the role of a tide plate only in an emergency when the amount of water has increased. Can do.

請求項６に記載の浸水防止構造は、防水板の側端部に互いに噛み合う凹凸又は段差が形成されるので、複数の防水板を方向に並べたときに防水板同士の間に間隙が生じることがなく、水の侵入を確実に防ぐことができる。 In the inundation preventing structure according to claim 6 , since unevenness or a step is formed at the side end portion of the waterproof board, a gap is generated between the waterproof boards when a plurality of waterproof boards are arranged in the direction. No intrusion of water can be reliably prevented.

請求項７に記載の浸水防止構造は、収納溝の底面よりも高い位置に底面が形成され水を貯留する貯留槽が設けられており、この貯留槽から収納溝までを連通する流入路が設けられている。そして流入路には開閉可能な規制弁が備わっているので、予め貯留槽に水を貯留しておいて、水が侵入するおそれがある緊急時にこの規制弁を開放することで、例えば津波のように外部に水が少ないが、数分以内に防水板を起立させる必要がある場合にも、収納溝内に一気に水を流入させることができ、防水板を迅速に起立させることができる。 The inundation prevention structure according to claim 7 is provided with a storage tank for storing water and having a bottom surface formed at a position higher than the bottom surface of the storage groove, and an inflow passage communicating from the storage tank to the storage groove is provided. It has been. And since the inflow channel is equipped with a control valve that can be opened and closed, by storing water in the storage tank in advance and opening this control valve in an emergency where water may invade, for example like a tsunami Even when there is little water outside, even when it is necessary to erect the waterproof plate within a few minutes, water can be made to flow into the storage groove at once, and the waterproof plate can be quickly raised.

収納溝２は防水板４が収納できる形状に掘り下げられて形成されており、その底部分に開閉可能な排水弁６を備えた排水口７が設けられている。この収納溝２は所定領域Ｙ側が深くなった貯水部２ａを形成しており、外部Ｘ側が水Ｗを貯水部２ａに導けるように下り勾配となった導水部２ｂを形成している。この収納溝２は例えばこの収納溝２の形状の型枠で打設養生されたプレキャストコンクリートをその上端が地面ＧＬよりも５ｃｍ程度高くなるように埋設して形成している。なお、収納溝２の材料及び工法はこれに限定されるものではなく、種々の材料及び工法を用いることができる。   The storage groove 2 is formed by digging into a shape that can store the waterproof plate 4, and a drain port 7 having a drain valve 6 that can be opened and closed is provided at the bottom portion thereof. The storage groove 2 forms a water reservoir 2a having a predetermined region Y side deeper, and the outer X side forms a water conduit 2b having a downward slope so that the water W can be guided to the water reservoir 2a. The storage groove 2 is formed, for example, by burying precast concrete that has been cast and cured with a mold having the shape of the storage groove 2 so that the upper end of the precast concrete is about 5 cm higher than the ground GL. In addition, the material and construction method of the storage groove | channel 2 are not limited to this, A various material and construction method can be used.

流入防止スロープ３は、例えば防錆処理された鉄などの金属により形成されており、外部Ｘから所定領域Ｙ側に向かって緩やかな上り勾配に形成されている。図２に良く示すように、流入防止スロープ３の所定領域Ｙ側の端部は、収納溝２の導水部２ｂの上方に突き出しており、この部分に収納溝２内に水Ｗを流入させる受入孔８が形成されている。この受入孔８は地面ＧＬからの高さαが５ｃｍ程度なっている。したがって、外部Ｘ側の水Ｗが地面ＧＬから５ｃｍ未満の場合は、流入防止スロープ３に阻まれて水Ｗが収納溝２内に流入することがなく、外部Ｘ側の水Ｗが地面ＧＬから５ｃｍ以上となると、水面の高さが受入孔８を越えるので、受入孔８から水Ｗが収納溝２内に流入し、収納溝２の導水部２ｂを流下して貯水部２ａに水Ｗが貯水されることになる。   The inflow prevention slope 3 is formed of a metal such as iron subjected to rust prevention, for example, and is formed with a gentle upward slope from the outside X toward the predetermined region Y side. As shown well in FIG. 2, the end of the inflow prevention slope 3 on the predetermined region Y side protrudes above the water guide portion 2 b of the storage groove 2, and accepts the water W into the storage groove 2 into this portion. A hole 8 is formed. The receiving hole 8 has a height α of about 5 cm from the ground GL. Therefore, when the water W on the external X side is less than 5 cm from the ground GL, the water W does not flow into the storage groove 2 due to the inflow prevention slope 3, and the water W on the external X side does not flow from the ground GL. If the height is 5 cm or more, the height of the water surface exceeds the receiving hole 8, so that the water W flows into the storage groove 2 from the receiving hole 8, flows down the water guide portion 2b of the storage groove 2, and the water W flows into the water storage portion 2a. It will be stored.

防水板４は、起立状態のときに下側になる部分が外部Ｘ側に膨らんで膨出部４ａを形成しており、上側となる部分は水Ｗの流入を阻止する板状部４ｂを形成している。この防水板４は例えばステンレス等の金属で形成されており、膨出部４ａの内部には発泡スチロールなどの比重の軽い樹脂の浮力体４ｃが内蔵されている。またこの防水板４は所定領域Ｙ側の収納溝２の上端に軸４ｎによって回動自在に固定されており、収納溝２の貯水部２ａに水Ｗが貯水されていないときには膨出部４ａの重さで外部Ｘ側に回転して倒れ、貯水部２ａに水Ｗが貯水され水位が上昇すると、膨出部４ａに加わる浮力によって次第に回動し起立する。   The waterproof plate 4 has a bulging portion 4a that bulges to the outside X side when it is in a standing state, and a plate-like portion 4b that blocks the inflow of water W. is doing. The waterproof plate 4 is made of, for example, a metal such as stainless steel, and a buoyant body 4c made of resin having a low specific gravity such as foamed polystyrene is built in the bulging portion 4a. The waterproof plate 4 is rotatably fixed to the upper end of the storage groove 2 on the predetermined area Y side by a shaft 4n. When the water W is not stored in the water storage part 2a of the storage groove 2, the waterproof plate 4 When the water W is stored in the water storage section 2a and falls down as the water level rises due to rotation to the external X side due to the weight, the water gradually rises due to the buoyancy applied to the bulging section 4a.

規制体５は、防水板４が起立したときに防水板４に当接するように、防水板４の両側端の所定領域Ｙ側に立設されており、防水板４が略鉛直に起立すると、この規制体５に当接してそれ以上防水板４が所定領域Ｙ側に倒れることを規制する。なお、図示しないがこの規制体５の防水板４と当接する面にはゴムなどの弾性体が貼り付けられて、規制体５と防水板４との間の水密性を向上させてもよい。   The restricting body 5 is erected on the predetermined region Y side at both ends of the waterproof plate 4 so as to come into contact with the waterproof plate 4 when the waterproof plate 4 stands. When the waterproof plate 4 stands up substantially vertically, It abuts against the restricting body 5 to restrict the waterproof plate 4 from falling further toward the predetermined region Y side. Although not shown, an elastic body such as rubber may be attached to the surface of the regulating body 5 that comes into contact with the waterproof board 4 to improve the watertightness between the regulating body 5 and the waterproof board 4.

以上のように、本実施形態の浸水防止構造１は、流入防止スロープ３により地面ＧＬから５ｃｍ以下の水Ｗが収納溝２に流入することを阻止するので、防水板４が不必要に起立して浸水防止構造１が設置された出入口などの通行を阻害することがない。また、浮力の力によって自動的に防水板４を起立させることで、故障のおそれも少なく、必要なときに確実に防水板４を起立させることができる。また、起立した状態の防水板４の高さに比べて収納溝２の深さを深くする必要がないので、安全に低コストで設置することができ、地中構造物などとも干渉するおそれを減らすことができる。   As described above, the infiltration prevention structure 1 of the present embodiment prevents the water W having a length of 5 cm or less from flowing into the storage groove 2 from the ground GL by the inflow prevention slope 3, so that the waterproof plate 4 stands up unnecessarily. Therefore, the passage of the entrance / exit where the inundation prevention structure 1 is installed is not obstructed. Further, by automatically erecting the waterproof plate 4 by the force of buoyancy, there is little risk of failure, and the waterproof plate 4 can be reliably erected when necessary. Further, since it is not necessary to increase the depth of the storage groove 2 as compared to the height of the standing waterproofing plate 4, it can be installed safely and at a low cost, and there is a risk of interfering with underground structures. Can be reduced.

〔第２の実施形態〕
次に、本発明の第２の実施形態の浸水防止構造１について図４及び図５を参照しつつ説明する。なお、第１の実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態の浸水防止構造１は、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、中間部に屈曲部４ｋを備えており略水平に倒伏した状態から略鉛直に起立した状態まで回動可能に設置された防水板４と、この防水板４をガイドするガイド溝９が設けられており、防水板４が起立した状態から所定領域Ｙ側に倒れこむことを防ぐ規制体５と、を備えている。 [Second Embodiment]
Next, an inundation preventing structure 1 according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. The inundation prevention structure 1 of this embodiment is provided with a storage groove 2 whose upper end opens toward the ground GL, an inflow prevention slope 3 provided on the external X side, and a bent portion 4k in the middle portion, and is lying down substantially horizontally. The waterproof plate 4 is installed so as to be rotatable from a state where the waterproof plate is erected to a substantially vertical state, and a guide groove 9 for guiding the waterproof plate 4 is provided. And a regulating body 5 that prevents the body from falling over.

防水板４は、膨出部４ａ及び板状部４ｂを備えており、この板状部４ｂが上部板体４ｄと下部板体４ｅとこれら上下の板体を連結する屈曲部４ｋとにより形成されている。屈曲部４ｋは例えば蝶番４ｆにより上部板体４ｄと下部板体４ｅとを互いに回転自在に構成しており、上部板体４ｄと下部板体４ｅとが折り重なった状態から展開した状態まで回転することができる。この防水板４は所定領域Ｙ側の収納溝２の上端に軸４ｎにより回動自在に固定されており、収納溝２の貯水部２ａに水Ｗが貯水されていないときには膨出部４ａの重さで外部Ｘ側に倒れ、貯水部２ａに水Ｗが貯水されると、膨出部４ａに加わる浮力によって回動し起立するように構成されている。   The waterproof plate 4 includes a bulging portion 4a and a plate-like portion 4b. The plate-like portion 4b is formed by an upper plate body 4d, a lower plate body 4e, and a bent portion 4k that connects these upper and lower plate bodies. ing. The bent portion 4k is configured such that the upper plate 4d and the lower plate 4e are rotatable with respect to each other by, for example, a hinge 4f, and the upper plate 4d and the lower plate 4e rotate from the folded state to the unfolded state. Can do. The waterproof plate 4 is rotatably fixed to the upper end of the storage groove 2 on the predetermined area Y side by a shaft 4n. When the water W is not stored in the water storage part 2a of the storage groove 2, the weight of the bulging part 4a is increased. Now, when the water W is fallen to the external X side and the water W is stored in the water storage part 2a, it is configured to rotate and stand up by buoyancy applied to the bulging part 4a.

そして、鉛直方向に立設する規制体５にはその長手方向に沿ってガイド溝９が設けられており、防水板４の上部板体４ｄの上側端に形成された突起がこのガイド溝９にスライド可能に係止されている。図４（Ａ）及び図５（Ａ）に示すように、収納溝２の貯水部２ａに水Ｗがないときに収納溝２に収納された状態で倒伏している防水板４は、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２の貯水部２ａに水Ｗが貯留されると、膨出部４ａに浮力が加わる。そして、膨出部４ａの浮力により防水板４が収納溝２の上端の軸４ｎにより起立方向に回転する。このとき防水板４の上部板体４ｄの上側端に形成された突起がガイド溝９にスライド可能に係止されているので、図４（Ｂ）及び図５（Ｂ）にあるように、屈曲部４ｋを展開方向に回転させながら、ガイド溝９を突起がスライドして、図４（Ｃ）及び図５（Ｃ）に示すように、防水板４が起立状態となる。   The regulating body 5 standing in the vertical direction is provided with a guide groove 9 along the longitudinal direction thereof, and a protrusion formed on the upper end of the upper plate body 4 d of the waterproof board 4 is formed in the guide groove 9. It is slidably locked. As shown in FIGS. 4 (A) and 5 (A), the waterproof plate 4 lying down in the state of being stored in the storage groove 2 when there is no water W in the water storage portion 2a of the storage groove 2 prevents inflow. When water W flows from the receiving hole 8 formed in the slope 3 and the water W is stored in the water storage portion 2a of the storage groove 2, buoyancy is applied to the bulging portion 4a. And the waterproof board 4 rotates to the standing direction by the shaft 4n of the upper end of the storage groove 2 by the buoyancy of the bulging part 4a. At this time, since the protrusion formed on the upper end of the upper plate 4d of the waterproof plate 4 is slidably locked in the guide groove 9, it is bent as shown in FIGS. 4 (B) and 5 (B). While the protrusion 4 slides in the guide groove 9 while rotating the portion 4k in the unfolding direction, the waterproof plate 4 stands up as shown in FIGS. 4C and 5C.

このように、防水板４は収納溝２に折り重ねられた状態で収納されるので、浸水防止構造１の近傍に他の構造物があるなどの理由で、収納溝２を設置するスペースが少ない場合にも充分な高さの防水板４を備えた浸水防止構造１とすることができる。   As described above, since the waterproof plate 4 is stored in a folded state in the storage groove 2, there is little space for installing the storage groove 2 because there is another structure in the vicinity of the inundation prevention structure 1. Even in such a case, it is possible to provide the infiltration prevention structure 1 including the waterproof plate 4 having a sufficient height.

〔第３の実施形態〕
次に、本発明の第３の実施形態の浸水防止構造１について図６を参照しつつ説明する。なお、第１の実施形態及び第２の実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態の浸水防止構造１は、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、中間部に屈曲部４ｋを備えており所定領域Ｙ側に例えば３０度程度傾いた状態から外部Ｘ側に略水平に倒伏した状態まで回動可能に設置された防水板４と、防水板４が鉛直に立ち上がった状態から所定領域Ｙ側に３０度以上倒れこむことを防ぐ規制体５と、を備えている。 [Third Embodiment]
Next, the infiltration prevention structure 1 of the 3rd Embodiment of this invention is demonstrated, referring FIG. In addition, about the structure similar to 1st Embodiment and 2nd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. The inundation prevention structure 1 of this embodiment includes a storage groove 2 whose upper end opens toward the ground GL, an inflow prevention slope 3 provided on the external X side, and a bent portion 4k in the middle portion, and a predetermined region Y side. For example, a waterproof plate 4 that can be rotated from a tilted state of about 30 degrees to a state of lying horizontally on the external X side, and a state where the waterproof plate 4 rises vertically from the vertical position to the predetermined region Y side by 30 degrees or more. And a regulating body 5 for preventing the body from falling down.

防水板４は、第２の実施形態と同様に、膨出部４ａ及び板状部４ｂを備えている。そして、膨出部４ａは、防水板４が起立した状態から所定領域Ｙ側に３０度以上倒れたときにも、この膨出部４ａの一部が収納溝２内に止まり、収納溝２内に貯留された水Ｗから浮力を受けることができるような形状に形成されている。また、この板状部４ｂは、上部板体４ｄと下部板体４ｅとこれら上下の板体を連結する屈曲部４ｋとにより形成されている。そして、屈曲部４ｋは例えば蝶番４ｆにより上部板体４ｄと下部板体４ｅとを互いに回転自在に構成しており、上部板体４ｄと下部板体４ｅとが折り重なった状態から展開した状態まで回転することができる。図６（Ｂ）に示すように、本実施形態においては、この屈曲部４ｋに、さらに展開方向に付勢する付勢手段４ｇが設けられている。この付勢手段４ｇは例えばその端部が下部板体４ｅと上部板体４ｄとにそれぞれ回転可能に固定された空圧シリンダにより構成されており、上部板体４ｄと下部板体４ｅとが折り重なった状態のときにシリンダ内の空気が圧縮されて展開方向に付勢する構成を採用することができる。なお、付勢手段４ｇは空圧シリンダに限定されるものではなく、油圧シリンダや他の弾性材料を用いて付勢するものであっても良い。   The waterproof board 4 is provided with the bulging part 4a and the plate-shaped part 4b similarly to 2nd Embodiment. And even when the bulging part 4a falls 30 degrees or more to the predetermined area Y side from the state where the waterproof plate 4 stands, a part of the bulging part 4a stops in the storage groove 2, and the inside of the storage groove 2 It is formed in a shape that can receive buoyancy from the water W stored in the tank. The plate-like portion 4b is formed by an upper plate 4d, a lower plate 4e, and a bent portion 4k that connects these upper and lower plates. The bent portion 4k is configured such that the upper plate 4d and the lower plate 4e are rotatable with respect to each other by, for example, a hinge 4f, and the upper plate 4d and the lower plate 4e are rotated from the folded state to the unfolded state. can do. As shown in FIG. 6B, in the present embodiment, the bent portion 4k is further provided with a biasing means 4g for biasing in the developing direction. The urging means 4g is composed of, for example, a pneumatic cylinder whose ends are rotatably fixed to the lower plate 4e and the upper plate 4d, respectively, and the upper plate 4d and the lower plate 4e are folded over. It is possible to employ a configuration in which the air in the cylinder is compressed and urged in the deployment direction when the state is in a state of being in a state. The biasing means 4g is not limited to a pneumatic cylinder, and may be biased using a hydraulic cylinder or other elastic material.

図６（Ａ）に示すように、収納溝２の貯水部２ａに水Ｗがないときには、防水板４は収納溝２に収納された状態で倒伏している。このとき、板状部４ｂの上部板体４ｄと下部板体４ｅとは、防水板４の自重により、付勢手段４ｇの展開方向への荷重に抗して、互いに折り重なった状態を保持している。そして、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２の貯水部２ａに水Ｗが貯留されると、膨出部４ａに浮力が加わる。そして、膨出部４ａの浮力により防水板４が収納溝２の上端の軸４ｎにより起立方向に回転する。このとき、図６（Ｂ）に示すように、防水板４は、その上部板体４ｄが付勢手段４ｇにより下部板体４ｅから離反する展開方向に回転し、図６（Ｃ）に示すように、上下の板体が面一になった状態で、所定領域Ｙ側に略３０度傾いて形成された規制体５に当接して、略３０度傾いた起立状態となる。   As shown in FIG. 6A, when there is no water W in the water storage portion 2 a of the storage groove 2, the waterproof plate 4 is lying down while being stored in the storage groove 2. At this time, the upper plate body 4d and the lower plate body 4e of the plate-like portion 4b hold the folded state against each other against the load in the deploying direction of the urging means 4g due to the weight of the waterproof plate 4. Yes. And if the water W flows in from the receiving hole 8 formed in the inflow prevention slope 3, and the water W is stored by the water storage part 2a of the storage groove 2, buoyancy will be added to the bulging part 4a. And the waterproof board 4 rotates to the standing direction by the shaft 4n of the upper end of the storage groove 2 by the buoyancy of the bulging part 4a. At this time, as shown in FIG. 6 (B), the waterproof plate 4 is rotated in the unfolding direction in which the upper plate 4d is separated from the lower plate 4e by the biasing means 4g, as shown in FIG. 6 (C). In addition, in a state where the upper and lower plate bodies are flush with each other, they come into contact with the regulating body 5 formed with an inclination of about 30 degrees toward the predetermined region Y, and are brought into an upright state inclined with about 30 degrees.

このように、防水板４は収納溝２に折り重ねられた状態で収納されるので、浸水防止構造１の近傍に他の構造物があるなどの理由で、収納溝２を設置するスペースが少ない場合にも充分な高さの防水板４を備えた浸水防止構造１とすることができる。そして、収納溝２に水Ｗが貯留され浮力が加わって、防水板４が起き上がるときに付勢手段４ｇにより自動的に屈曲部４ｋが展開して防水板４の高さをかさ上げするので、緊急時に確実に必要な高さの防水板４を起立させることができる。また、防水板４は所定領域Ｙ側に３０度傾いた状態で起立するので、外部Ｘから所定領域Ｙに向かって勢いのある水流が流れ込もうとしたときに、防水板４に水流が衝突して加わる荷重を防水板４の傾きにより上方に逃がすことができる。   As described above, since the waterproof plate 4 is stored in a folded state in the storage groove 2, there is little space for installing the storage groove 2 because there is another structure in the vicinity of the inundation prevention structure 1. Even in such a case, it is possible to provide the infiltration prevention structure 1 including the waterproof plate 4 having a sufficient height. And since the water W is stored in the storage groove 2 and buoyancy is applied, and the waterproof plate 4 rises, the bending portion 4k is automatically expanded by the urging means 4g to raise the height of the waterproof plate 4. The waterproof plate 4 having a necessary height can be surely raised in an emergency. In addition, since the waterproof plate 4 stands up in a state inclined by 30 degrees toward the predetermined region Y, the water flow collides with the waterproof plate 4 when a strong water flow flows from the outside X toward the predetermined region Y. Thus, the applied load can be released upward by the inclination of the waterproof plate 4.

なお、本実施形態においては、防水板４が所定領域Ｙ側に傾く角度を略３０度としたが、これに限定されるものではなく、想定される水流の勢いなどの要素を考慮して適宜選択することができる。   In the present embodiment, the angle at which the waterproof plate 4 is inclined toward the predetermined region Y side is set to approximately 30 degrees. However, the angle is not limited to this, and is appropriately determined in consideration of factors such as an assumed water flow momentum. You can choose.

〔第４の実施形態〕
次に、本発明の第４の実施形態の浸水防止構造１について図７を参照しつつ説明する。なお、第１の実施形態から第３の実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態の浸水防止構造１は、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、中間部に屈曲部４ｋを備えており所定領域Ｙ側に例えば３０度程度傾いた状態から外部Ｘ側に略水平に倒伏した状態まで回動可能に設置された防水板４と、防水板４が鉛直に立ち上がった状態から所定領域Ｙ側に３０度以上倒れこむことを防ぐ規制体５と、防水板４が略鉛直となる方向に付勢する付勢部材１０とを備えている。なお、付勢部材１０以外の構成については第３の実施形態と同様であるので説明を省略する。 [Fourth Embodiment]
Next, a flood prevention structure 1 according to a fourth embodiment of the present invention will be described with reference to FIG. In addition, about the structure similar to 1st Embodiment to 3rd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. The inundation prevention structure 1 of this embodiment includes a storage groove 2 whose upper end opens toward the ground GL, an inflow prevention slope 3 provided on the external X side, and a bent portion 4k in the middle portion, and a predetermined region Y side. For example, a waterproof plate 4 that can be rotated from a tilted state of about 30 degrees to a state of lying horizontally on the external X side, and a state where the waterproof plate 4 rises vertically from the vertical position to the predetermined region Y side by 30 degrees or more. A restricting body 5 that prevents the body from falling down and a biasing member 10 that biases the waterproof board 4 in a substantially vertical direction are provided. The configuration other than the urging member 10 is the same as that of the third embodiment, and a description thereof will be omitted.

付勢部材１０は、図示しないが内部に流体が閉じ込められたシリンダとこのシリンダに挿入されるプランジャにより構成されており、プランジャがシリンダの抜出方向及び挿入方向にスライドすることによりシリンダ内部の体積を増減させ、内部の流体を膨張又は圧縮しつつ伸縮可能に構成されている。なお、付勢部材１０はプランジャ及びシリンダに換えてゴム、バネなどの弾性部材を用いてもよい。   Although not shown, the urging member 10 includes a cylinder in which a fluid is confined and a plunger inserted into the cylinder. The plunger slides in the cylinder extraction direction and the insertion direction so that the volume inside the cylinder is increased. It is possible to expand and contract while expanding or compressing the fluid inside. The urging member 10 may use an elastic member such as rubber or a spring instead of the plunger and the cylinder.

図７（Ａ）に示すように、収納溝２の貯水部２ａに水Ｗがないときには、防水板４は収納溝２に収納された状態で倒伏している。このとき、付勢部材１０は伸長された状態となっており、シリンダ内部の体積が増えて流体が膨張し、縮退方向に付勢するが、防止板はその自重により、付勢部材１０の荷重に抗して収納溝２に収納された状態を維持している。そして、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２の貯水部２ａに水Ｗが貯留されると、防水板４の膨出部４ａに浮力が加わる。   As shown in FIG. 7A, when there is no water W in the water storage portion 2 a of the storage groove 2, the waterproof plate 4 is lying down while being stored in the storage groove 2. At this time, the urging member 10 is in an extended state, the volume inside the cylinder increases, the fluid expands and urges in the retracting direction, but the prevention plate is loaded by the urging member 10 by its own weight. The state of being stored in the storage groove 2 is maintained against this. And if the water W flows in from the receiving hole 8 formed in the inflow prevention slope 3, and the water W is stored by the water storage part 2a of the storage groove 2, a buoyancy will be added to the bulging part 4a of the waterproof board 4. FIG.

そして、この膨出部４ａに加わる浮力と、付勢部材１０が縮退しようとする荷重と、により、防水板４が収納溝２の上端の軸４ｎにより起立方向に回転し、図２（Ｂ）に示すように、略鉛直に立ち上がった状態に保持される。この防水板４の立ち上がりに従って、付勢部材１０は縮退し、防水板４が略鉛直の状態となったときに、内部の流体の圧力が外気圧とほぼ釣り合うように構成されている。これにより、防水板４に外部Ｘ側からの水圧がかかっていないときには、防水板４は略鉛直に立ち上がった状態を維持する。その後、外部Ｘ側からさらに水圧が加わった時には、防水板４は、図７（Ｃ）に示すように、所定領域Ｙ側に傾いて、付勢部材１０がさらに縮退し、付勢部材１０内部の流体が圧縮される。   Then, due to the buoyancy applied to the bulging portion 4a and the load to which the urging member 10 is to be retracted, the waterproof plate 4 is rotated in the standing direction by the shaft 4n at the upper end of the storage groove 2, and FIG. As shown in FIG. 4, the state is maintained in a state of rising substantially vertically. As the waterproof plate 4 rises, the urging member 10 is degenerated, and when the waterproof plate 4 is in a substantially vertical state, the pressure of the internal fluid is substantially balanced with the external pressure. Thereby, when the water pressure from the external X side is not applied to the waterproof board 4, the waterproof board 4 maintains the state stood up substantially perpendicularly. Thereafter, when further water pressure is applied from the outside X side, the waterproof plate 4 is inclined to the predetermined region Y side as shown in FIG. 7C, and the urging member 10 is further retracted, and the inside of the urging member 10 The fluid is compressed.

このように、防水板４が起立したときに、付勢部材１０がこの防水板４を略鉛直となる方向に付勢するので、外部Ｘ側から所定領域Ｙに向かって勢いのある水流が流れ込もうとしたときには、防水板４にかかる水流の圧力により付勢部材１０の付勢力に抗して防水板４が所定領域Ｙ側に傾くので、水流の勢いを弱めることができ、また、防水板４が所定領域Ｙ側に傾くことにより、この水流の圧力を上方に逃がすことができる。一方、付勢部材１０の付勢力よりも弱い水流や水圧の場合は、防水板４は略鉛直な状態のままであり、防水板４の高さが高い状態を維持することができる。   Thus, when the waterproof board 4 stands up, the urging member 10 urges the waterproof board 4 in a substantially vertical direction, so that a strong water flow flows from the external X side toward the predetermined region Y. When trying to insert, the waterproof plate 4 tilts toward the predetermined region Y against the urging force of the urging member 10 due to the pressure of the water flow applied to the waterproof plate 4, so that the force of the water flow can be weakened. When the plate 4 is inclined toward the predetermined area Y, the pressure of this water flow can be released upward. On the other hand, when the water flow or the water pressure is weaker than the urging force of the urging member 10, the waterproof plate 4 remains in a substantially vertical state, and the waterproof plate 4 can maintain a high height.

〔第５の実施形態〕
次に、本発明の第５の実施形態の浸水防止構造１について図８から図１１を参照しつつ説明する。なお、上述の各実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態に係る浸水防止構造１は、図８に示すように、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、収納溝２内に収納される浮力体４ｃを有し、収納溝２内に水Ｗが注入されると、上方にスライドして起立する防水板４と、を備えている。 [Fifth Embodiment]
Next, a flood prevention structure 1 according to a fifth embodiment of the present invention will be described with reference to FIGS. In addition, about the structure similar to each above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 8, the inundation preventing structure 1 according to this embodiment is housed in the housing groove 2 whose upper end opens toward the ground GL, the inflow prevention slope 3 provided on the external X side, and the housing groove 2. And a waterproof plate 4 that slides upward and rises when water W is poured into the storage groove 2.

収納溝２はこの実施形態の防水板４を収納するために鉛直方向に掘り下げられており、その底部分に開閉可能な排水弁６を備えた排水口７が設けられている。防水板４は、図９に示すように、下側が収納溝２内で上下方向にスライド可能に形成されており、上側が上下方向の中間位置で上部板体４ｄと下部板体４ｅとに折り曲げ可能な屈曲部４ｋを備えた板状に形成されている。防水板４は、ステンレスの平板の一方の面にリブ４ｈが格子状に形成された形状であって、リブ４ｈ同士の間には発泡スチロール製の浮力体４ｃが嵌着されている。屈曲部４ｋは蝶番４ｆにより上部板体４ｄと下部板体４ｅとを折り重なった状態から面一に展開された状態まで回転させることができるものであって、たとえば空圧シリンダにより形成された付勢手段４ｇによって展開方向に付勢されている。   The storage groove 2 is dug down in the vertical direction to store the waterproof plate 4 of this embodiment, and a drain port 7 having a drain valve 6 that can be opened and closed is provided at the bottom thereof. As shown in FIG. 9, the waterproof plate 4 is formed such that the lower side is slidable in the vertical direction within the storage groove 2, and the upper side is bent into an upper plate 4d and a lower plate 4e at an intermediate position in the vertical direction. It is formed in a plate shape with possible bent portions 4k. The waterproof plate 4 has a shape in which ribs 4h are formed in a lattice pattern on one surface of a stainless steel flat plate, and a buoyant body 4c made of polystyrene foam is fitted between the ribs 4h. The bent portion 4k can rotate the upper plate 4d and the lower plate 4e with a hinge 4f from a state where the upper plate 4d and the lower plate 4e are overlapped to a state where the upper plate 4d and the lower plate 4e are unfolded. It is urged in the deployment direction by means 4g.

防水板４の両側端には、段差４ｉが形成されている。この段差４ｉは、図１０に示すように、複数の防水板４を隣り合うように並べた際に互いに噛み合う形状である。したがって、浸水防止構造１を設置する必要がある地下構造物への出入り口、公共道路から敷地に入る出入り口などの幅が広い場合のように、複数の防水板４を隣り合うように並べた浸水防止構造１を設置する必要がある場合に、防水板４の両側端が噛み合うことで、水Ｗの侵入をより確実に防ぐことができる。なお、防水板４の両側端の形状は段差４ｉを設けたものに限定されず、例えば図１１に示すように互いに噛み合い可能な凹凸４ｊを設けたものであってもよい。凹凸４ｊのほうが段差４ｉよりも接合箇所の防水性能をより高めることができる。   Steps 4 i are formed at both ends of the waterproof plate 4. As shown in FIG. 10, the step 4i has a shape that meshes with each other when a plurality of waterproof plates 4 are arranged adjacent to each other. Therefore, inundation prevention in which a plurality of waterproof plates 4 are arranged next to each other as in the case of wide entrances and exits to underground structures where it is necessary to install the inundation prevention structure 1 and entrances and exits from public roads. When it is necessary to install the structure 1, the both ends of the waterproof plate 4 are engaged with each other, so that the intrusion of the water W can be prevented more reliably. In addition, the shape of the both ends of the waterproof board 4 is not limited to what provided the level | step difference 4i, For example, as shown in FIG. 11, what provided the unevenness | corrugation 4j which can mutually mesh | engage may be provided. The unevenness 4j can further improve the waterproof performance of the joint portion than the step 4i.

図８（Ａ）に示すように、収納溝２に水Ｗがないときには、防水板４は収納溝２内に収納されている。このとき、防水板４の屈曲部４ｋは付勢手段４ｇにより上部板体４ｄと下部板体４ｅとが互いに展開する方向に付勢されているが、防水板４は鉛直方向に掘り下げられた収納溝２内に収納されているため上部板体４ｄ及び下部板体４ｅが互いに広がることなく折り重ねられた状態を保持されている。   As shown in FIG. 8A, when there is no water W in the storage groove 2, the waterproof plate 4 is stored in the storage groove 2. At this time, the bent portion 4k of the waterproof board 4 is urged by the urging means 4g in the direction in which the upper plate body 4d and the lower plate body 4e are developed from each other. However, the waterproof board 4 is stored in the vertical direction. Since it is stored in the groove 2, the upper plate 4d and the lower plate 4e are held in a folded state without spreading each other.

そして、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２に水Ｗが貯留されると、防水板４に浮力が加わり、図８（Ｂ）に示すように、防水板４が収納溝２から上方にスライドして起立する。防水板４が上方にスライドして起立すると、防水板４の上部板体４ｄが付勢手段４ｇにより下部板体４ｅから離反する展開方向に回転し、図８（Ｃ）に示すように、上下の板体が面一になった状態で、鉛直方向に起立する。   When water W flows from the receiving hole 8 formed in the inflow prevention slope 3 and the water W is stored in the storage groove 2, buoyancy is applied to the waterproof plate 4, as shown in FIG. 8B. The waterproof plate 4 slides upward from the storage groove 2 and stands up. When the waterproof plate 4 slides upward and stands, the upper plate 4d of the waterproof plate 4 is rotated in the unfolding direction away from the lower plate 4e by the biasing means 4g, and as shown in FIG. Stands vertically in a state where the plate body is flush.

以上のように本実施形態の浸水防止構造１によると、防水板４は、収納溝２内に収納される浮力体４ｃを有し、この収納溝２内に水Ｗが注入されて浮力体４ｃに浮力が加わると上方にスライドして起立し外部Ｘから所定領域Ｙ内への水Ｗの流入を阻止するので、人による操作や電気的な制御を必要とせず、簡単で故障しにくい構成にすることができる。また、防水板４は、上下方向の中間部に折り曲げ可能な屈曲部４ｋを備えており、収納溝２に折り重ねられた状態で収納されるので、収納溝２に収納する際の防水板４の高さを低くすることができ、収納溝２の深さが比較的深くならず、設置コストを低減することができ、地中に構造物があるような場合も干渉することなく設置することができる。   As described above, according to the inundation prevention structure 1 of the present embodiment, the waterproof plate 4 has the buoyancy body 4c stored in the storage groove 2, and water W is injected into the storage groove 2 so that the buoyancy body 4c. When buoyancy is applied, it slides upward and stands up to prevent the flow of water W from the external X into the predetermined area Y, so that it does not require any human operation or electrical control, and it is simple and not easily damaged. can do. Further, the waterproof plate 4 includes a bendable portion 4k that can be bent at an intermediate portion in the vertical direction, and is stored in a state of being folded in the storage groove 2, so that the waterproof plate 4 when stored in the storage groove 2 is provided.

〔第６の実施形態〕
次に、本発明の第６の実施形態の浸水防止構造１について図１２を参照しつつ説明する。なお、上述の各実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態に係る浸水防止構造１は、図１２に示すように、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、収納溝２内に収納される浮力体４ｃを有し、収納溝２内に水Ｗが注入されると、上方にスライドして起立する防水板４と、を備えている。 [Sixth Embodiment]
Next, a flood prevention structure 1 according to a sixth embodiment of the present invention will be described with reference to FIG. In addition, about the structure similar to each above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 12, the infiltration preventing structure 1 according to this embodiment is accommodated in the accommodation groove 2 whose upper end opens toward the ground GL, the inflow prevention slope 3 provided on the external X side, and the accommodation groove 2. And a waterproof plate 4 that slides upward and rises when water W is poured into the storage groove 2.

収納溝２はこの実施形態の防水板４を収納するために下方が外部Ｘ側に傾くように傾斜して掘り下げられている。このように構成すると、図１２（Ａ）に示すように、収納溝２に水Ｗがないときには、防水板４は収納溝２内に上部板体４ｄ及び下部板体４ｅが互いに折り重ねられた状態で収納されている。そして、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２に水Ｗが貯留されると、防水板４に浮力が加わり、図１２（Ｂ）に示すように、防水板４が収納溝２から所定領域Ｙ側に傾いて斜め上方にスライドして起立する。そして、防水板４が起立すると、防水板４の上部板体４ｄが付勢手段４ｇにより下部板体４ｅから離反する展開方向に回転し、図１２（Ｃ）に示すように、上下の板体が面一になった状態で、所定領域Ｙ側に傾いた状態で維持される。   In order to store the waterproof plate 4 of this embodiment, the storage groove 2 is deeply dug down so that the lower side is inclined toward the external X side. With this configuration, as shown in FIG. 12A, when there is no water W in the storage groove 2, the waterproof plate 4 has the upper plate body 4d and the lower plate body 4e folded together in the storage groove 2. It is stored in a state. Then, when water W flows from the receiving hole 8 formed in the inflow prevention slope 3 and the water W is stored in the storage groove 2, buoyancy is applied to the waterproof plate 4, as shown in FIG. The waterproof plate 4 is tilted from the storage groove 2 toward the predetermined region Y and slid obliquely upward to stand. When the waterproof plate 4 stands up, the upper plate 4d of the waterproof plate 4 is rotated in the unfolding direction away from the lower plate 4e by the biasing means 4g, and as shown in FIG. Is maintained in a state of being flush with the predetermined region Y side.

このように、本実施形態の浸水防止構造１によると、防水板４が起立したときに、所定領域Ｙ側に傾くので、外部Ｘから所定領域Ｙに向かって勢いのある水流が流れ込もうとしたときに、防水板４に水流が衝突して加わる荷重を防水板４の傾きにより上方に逃がすことができる。   Thus, according to the inundation preventing structure 1 of the present embodiment, when the waterproof plate 4 stands up, the waterproof plate 4 is inclined toward the predetermined region Y, so that a strong water flow flows from the external X toward the predetermined region Y. Then, the load applied by the water flow colliding with the waterproof board 4 can be released upward by the inclination of the waterproof board 4.

なお、本実施形態においては、収納溝２が下方が外部Ｘ側に傾くように傾斜して掘り下げられているが、収納溝２の形状はこれに限定されるものではなく、例えば、図１３に示すように、鉛直方向に掘り下げられるとともに、上端付近に防水板４を傾けることができる傾斜空間２ｃを有する形状としてもよい。このように構成すると、図１３（Ａ）に示すように、収納溝２に水Ｗがないときには、防水板４は収納溝２内に上部板体４ｄ及び下部板体４ｅが互いに折り重ねられた状態で収納されており、流入防止スロープ３に形成された受入孔８から水Ｗが流入して、収納溝２に水Ｗが貯留されると、防水板４に浮力が加わり、図１３（Ｂ）に示すように、防水板４が収納溝２から鉛直方向にスライドして立ち上がる。そして、防水板４が起立すると、防水板４の上部板体４ｄが付勢手段４ｇにより下部板体４ｅから離反する展開方向に回転する。そして、防水板４に外部Ｘ側から水圧が加わったときに、図１３（Ｃ）に示すように、防水板４が上下の板体が面一になった状態で、所定領域Ｙ側に傾く。このように構成された場合でも、外部Ｘから所定領域Ｙに向かって勢いのある水流が流れ込もうとしたときに、防水板４に水流が衝突して加わる荷重を防水板４の傾きにより上方に逃がすことができる。   In this embodiment, the storage groove 2 is inclined and dug down so that the lower side is inclined toward the external X side. However, the shape of the storage groove 2 is not limited to this, for example, as shown in FIG. As shown, it is good also as a shape which has the inclined space 2c which can be digged down in the perpendicular direction and can incline the waterproof board 4 near the upper end. With this configuration, as shown in FIG. 13A, when there is no water W in the storage groove 2, the waterproof plate 4 has the upper plate body 4d and the lower plate body 4e folded together in the storage groove 2. When the water W flows from the receiving hole 8 formed in the inflow prevention slope 3 and the water W is stored in the storage groove 2, buoyancy is applied to the waterproof plate 4, and FIG. ), The waterproof plate 4 slides up from the storage groove 2 in the vertical direction. When the waterproof plate 4 stands up, the upper plate 4d of the waterproof plate 4 is rotated in the unfolding direction away from the lower plate 4e by the biasing means 4g. When water pressure is applied to the waterproof board 4 from the outside X side, as shown in FIG. 13C, the waterproof board 4 is inclined to the predetermined region Y side with the upper and lower plate bodies being flush with each other. . Even when configured in this manner, when a strong water flow flows from the outside X toward the predetermined region Y, the load applied by the water flow colliding with the waterproof plate 4 is increased due to the inclination of the waterproof plate 4. Can escape.

〔第７の実施形態〕
次に、本発明の第７の実施形態の浸水防止構造１について図１４を参照しつつ説明する。なお、上述の各実施形態と同様の構成については同一の符号を付して説明を省略する。この実施形態に係る浸水防止構造１は、図１４に示すように、上端が地面ＧＬに向かって開口する収納溝２と、外部Ｘ側に設けられる流入防止スロープ３と、収納溝２内に収納される浮力体４ｃを有し、収納溝２内に水Ｗが注入されると、上方にスライドして起立する防水板４と、防水板４の所定領域Ｙ側に設置される堤防１１と、その底面が地面ＧＬと同じ高さとなるように設置された水Ｗを貯留する貯留槽１２と、一端がこの貯留槽１２の底面に設けられた流出口１３に連通するとともに、他端が収納溝２に設けられた注入口１４に連通する流入路１５と、この流入路１５上に開閉可能に設けられる規制弁１６とを備えている。 [Seventh Embodiment]
Next, a flood prevention structure 1 according to a seventh embodiment of the present invention will be described with reference to FIG. In addition, about the structure similar to each above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted. As shown in FIG. 14, the inundation preventing structure 1 according to this embodiment is housed in the housing groove 2 whose upper end opens toward the ground GL, the inflow prevention slope 3 provided on the external X side, and the housing groove 2. When the water W is poured into the storage groove 2, the waterproof plate 4 that slides up and stands up, and the levee 11 that is installed on the predetermined region Y side of the waterproof plate 4, The storage tank 12 for storing the water W installed so that the bottom surface thereof is at the same height as the ground GL, one end communicates with the outlet 13 provided on the bottom surface of the storage tank 12, and the other end is the storage groove. 2 is provided with an inflow passage 15 communicating with an inlet 14 provided in the position 2, and a regulation valve 16 provided on the inflow passage 15 so as to be openable and closable.

収納溝２は、防水板４を収納するために下方が外部Ｘ側に傾くように傾斜して掘り下げられている。堤防１１は、その外部Ｘ側の面が収納溝２の所定領域Ｙ側の面と面一になるように、傾斜して形成されており、防水板４が収納溝２に沿って斜め上方にスライドした時に、この防水板４が堤防１１の外部Ｘ側の面と当接するように形成されている。貯留槽１２は、少なくとも収納溝２の容積とほぼ等しい容積以上の水Ｗを、貯留できる大きさであって、常時水Ｗが貯留されるように管理されている。この貯留槽１２には、図示しないが、例えばフロート弁機構が設けられており、所定以下の貯留水量となった場合に水道から水Ｗを流入できる構成となっている。また、図示しないが、この貯留槽１２は少なくとも、規制弁１６を開放した場合に貯留槽１２内の水Ｗが流入路１５を通って収納溝２に流入できるように、上部に空気孔が設けられている。   In order to store the waterproof plate 4, the storage groove 2 is dug down so as to be inclined downward toward the external X side. The dike 11 is formed to be inclined so that the surface on the outside X side thereof is flush with the surface on the predetermined region Y side of the storage groove 2, and the waterproof plate 4 is obliquely upward along the storage groove 2. The waterproof plate 4 is formed so as to come into contact with the surface on the outside X side of the bank 11 when sliding. The storage tank 12 is sized to store at least a volume of water W approximately equal to or larger than the volume of the storage groove 2 and is managed so that the water W is always stored. Although not shown, the storage tank 12 is provided with a float valve mechanism, for example, so that water W can flow from the water when the amount of stored water is less than or equal to a predetermined value. Although not shown, this storage tank 12 is provided with an air hole at the top so that at least when the regulating valve 16 is opened, the water W in the storage tank 12 can flow into the storage groove 2 through the inflow passage 15. It has been.

流入路１５は、例えば塩化ビニルなどの樹脂又は金属で形成された管であって、貯留槽１２内の水Ｗを収納溝２にたとえば１分間などの所定時間以内に流入させることができる径を有している。規制弁１６は、手動又は電気制御で流入路１５を開放及び閉鎖可能な弁である。   The inflow path 15 is a pipe formed of a resin or metal such as vinyl chloride, for example, and has a diameter that allows the water W in the storage tank 12 to flow into the storage groove 2 within a predetermined time such as 1 minute. Have. The restriction valve 16 is a valve that can open and close the inflow passage 15 manually or electrically.

例えば津波の場合のように、流入防止スロープ３に形成された受入孔８からの水Ｗの流入を待つことなく、防水板４を立ち上げる必要がある場合に、規制弁１６を例えば電気制御で開放すると、貯留槽１２内に貯留されていた水Ｗが流入路１５を通って、収納溝２内に流入する。収納溝２内に水Ｗが流入すると、防水板４に浮力が加わり、防水板４が収納溝２から所定領域Ｙ側に傾いて斜め上方にスライドして起立する。そして、防水板４が起立すると、防水板４の上部板体４ｄが付勢手段４ｇにより下部板体４ｅから離反する展開方向に回転し、図１４（Ｂ）に示すように、上下の板体が面一になった状態で、所定領域Ｙ側に傾いた状態で維持される。   For example, when the waterproof plate 4 needs to be raised without waiting for the inflow of water W from the receiving hole 8 formed in the inflow prevention slope 3 as in the case of a tsunami, the regulating valve 16 is electrically controlled, for example. When opened, the water W stored in the storage tank 12 flows into the storage groove 2 through the inflow path 15. When the water W flows into the storage groove 2, buoyancy is applied to the waterproof plate 4, and the waterproof plate 4 tilts upward from the storage groove 2 toward the predetermined region Y and rises obliquely upward. When the waterproof plate 4 stands up, the upper plate 4d of the waterproof plate 4 is rotated in the unfolding direction away from the lower plate 4e by the urging means 4g, and as shown in FIG. Is maintained in a state of being flush with the predetermined region Y side.

このように、本実施形態の浸水防止構造１によると、必要に応じて、外部Ｘからの水Ｗの流入を待つことなく防水板４を立ち上げることができるので、防水板４を即座に立ち上げる必要がある場合に好適である。また、そこまでの緊急性を要しない場合には、外部Ｘからの水Ｗの流入により、防水板４を立ち上げることができるので、より確実に浸水を防止することができる。また、防水板４の所定領域Ｙ側に堤防１１が設置されることで、防水板４のみで浸水を防止する場合に比べてより強度を増すことができる。   Thus, according to the inundation prevention structure 1 of the present embodiment, the waterproof plate 4 can be started up without waiting for the inflow of the water W from the external X as needed. It is suitable when it is necessary to raise. Moreover, when the urgency so far is not required, the waterproof plate 4 can be started up by the inflow of the water W from the outside X, so that the flooding can be more reliably prevented. In addition, by installing the levee 11 on the predetermined area Y side of the waterproof plate 4, the strength can be further increased as compared with the case where the waterproof plate 4 alone prevents flooding.

なお、本実施形態においては、上方にスライドして起立する防水板４を用いた浸水防止構造１に、堤防１１、貯留槽１２、及び流入路１５を備える構成としたが、例えば図１５に示すように、略水平に倒伏した状態から所定領域側に傾いた状態まで回動可能に設置された防水板４を用いた浸水防止構造１が、堤防１１、貯留槽１２、及び流入路１５を備える構成としてもよい。堤防１１は防水板４が所定領域Ｙ側に所定の角度以上傾くことを規制できるように、外部Ｘ側の面が傾斜して形成されており、前述の規制体５の役割を兼ねることができる。また貯留槽１２は流入路１５に設けられた規制弁１６を開放したときに、貯留槽１２内の水が収納溝に流れ込むことができる高さがあれば地中に埋設されていてもよい。なお、図示しないが、貯留槽１２、及び流入路１５を設けずに、堤防１１のみを設けてもよい。堤防１１を有することで防水板４を補強することができる。   In addition, in this embodiment, although it was set as the structure provided with the dike 11, the storage tank 12, and the inflow path 15 in the inundation prevention structure 1 using the waterproof board 4 which slides upwards, it shows, for example in FIG. As described above, the inundation prevention structure 1 using the waterproof plate 4 that is installed so as to be able to rotate from a state of lying down substantially horizontally to a state of tilting toward a predetermined region includes a dike 11, a storage tank 12, and an inflow channel 15. It is good also as a structure. The dike 11 is formed with an inclined surface on the external X side so that the waterproof plate 4 can be restricted from tilting to a predetermined region Y side by a predetermined angle or more, and can also serve as the aforementioned regulating body 5. . The storage tank 12 may be buried in the ground as long as the water in the storage tank 12 can flow into the storage groove when the regulating valve 16 provided in the inflow passage 15 is opened. Although not shown, only the bank 11 may be provided without providing the storage tank 12 and the inflow channel 15. The waterproof board 4 can be reinforced by having the bank 11.

なお、本発明の実施の形態は上述の各形態に限ることなく、本発明の思想の範囲を逸脱しない範囲で適宜変更することができることは云うまでもない。   Needless to say, the embodiments of the present invention are not limited to the above-described embodiments, and can be appropriately changed without departing from the scope of the idea of the present invention.

本発明に係る浸水防止構造１は、外部Ｘから所定領域Ｙ内に水Ｗが浸水することを防止する浸水防止構造１として好適に用いることができる。   The infiltration prevention structure 1 according to the present invention can be suitably used as the infiltration prevention structure 1 that prevents the water W from entering the predetermined region Y from the outside X.
