以下、本発明の止水ユニットの実施の形態について、添付図面を参照して詳細に説明する。図１は本発明の一実施形態に係る止水ユニット１を設置した地下施設の出入口を説明する図、図２は本発明の一実施形態に係る止水ユニット１の縦断面図、図３は図２の止水ユニット１において止水部３０が上昇した状態を説明する図である。   Hereinafter, embodiments of a water stop unit of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram illustrating an entrance / exit of an underground facility where a water stop unit 1 according to an embodiment of the present invention is installed, FIG. 2 is a longitudinal sectional view of the water stop unit 1 according to an embodiment of the present invention, and FIG. It is a figure explaining the state which the water stop part 30 rose in the water stop unit 1 of FIG.

図１、図２に示すように、本実施形態の止水ユニット１は、地下鉄や地下街等の地下施設、又は建物の出入口５０等に設置されるもので、筐体１１と、開口部２０と、排水部２１と、止水部３０と、案内部４０とを備える。なお、図２において、案内部４０は破線で示してある。   As shown in FIGS. 1 and 2, the water stop unit 1 of the present embodiment is installed in an underground facility such as a subway or an underground mall, or an entrance / exit 50 of a building, and includes a housing 11, an opening 20, The drainage part 21, the water stop part 30, and the guide part 40 are provided. In FIG. 2, the guide part 40 is indicated by a broken line.

筐体１１は、人や車両が通行する通路面ＧＬの上にアンカーボルトやステー等で固定されることで設置され、本実施形態の止水ユニット１では階段状をなし、出入口５０の階段５１の段差に続けて設置されている。また、筐体１１は、その内部に水を貯留できる構成となっている。なお、本実施形態の止水ユニット１では、筐体１１の内部そのものに水を貯留するが、筐体１１の内部を仕切り、別に貯水槽等を設ける構成としてもよい。   The casing 11 is installed on a passage surface GL through which a person or a vehicle passes by anchor bolts, stays, or the like. In the water stop unit 1 according to the present embodiment, a staircase is formed, and a staircase 51 at an entrance 50 is formed. It is installed following the level difference. Moreover, the housing | casing 11 becomes a structure which can store water in the inside. In addition, in the water stop unit 1 of this embodiment, water is stored in the inside of the housing 11 itself, but the inside of the housing 11 may be partitioned and a water storage tank or the like may be provided separately.

開口部２０は、集中豪雨等による洪水で水が通路面ＧＬに溢れたときに、筐体１１の内部に水を導入するもので、階段状になった筐体１１の１段目と２段目との間の垂直面のうち、屋外側に複数設けられる。   The opening 20 introduces water into the housing 11 when water overflows the passage surface GL due to flooding due to heavy rain, etc. The first and second steps of the housing 11 are stepped. Among the vertical planes between the eyes, a plurality are provided on the outdoor side.

排水部２１は、筐体１１の内部に導入された水を排水するもので、筐体１１の底面に設けられ、図示しない下水管等に接続される。なお、この排水部２１の開口面積は、複数の開口部２０を合わせた開口面積より小さく構成されており、時間当たりの排水量は、開口部２０から流入してくる水の量より少ない。このため、開口部２０から水が流入している間は、水が筐体１１の内部に貯留され、周囲の水位が低下して開口部２０から水が流入しなくなると、筐体１１の内部の水はなくなる。   The drainage unit 21 drains water introduced into the housing 11, is provided on the bottom surface of the housing 11, and is connected to a sewer pipe (not shown). In addition, the opening area of this drainage part 21 is comprised smaller than the opening area which put together the some opening part 20, and the amount of drainage per time is smaller than the quantity of the water which flows in from the opening part 20. FIG. For this reason, while water flows in from the opening 20, water is stored inside the housing 11, and when the surrounding water level decreases and water stops flowing from the opening 20, The water is gone.

止水部３０は、止水板３１と、天板３３と、ローラ３４とを備える。止水板３１は、垂直方向にその広い面を向けた板状の部材であり、その内部が中空とされることで、水から浮力を得ることができる。また、止水板３１の下部は、ローラ３４が設けられる部分を除き、拡幅されて断面略逆Ｔ字状をなしている。この拡幅された部分３２も中空構造とされ、当該部分においても水に対する浮力を得ることができる。天板３３は、止水板３１の上面に設けられるもので、止水板３１が下降した際、筐体１１の最上段の上面１５と同じ高さとなるよう構成される。ローラ３４は、止水板３１の長手方向の両端部に複数設けられるもので、筐体１１の内部に水が貯留されたとき、又は貯留後に排水されたとき、止水板３１が滑らかに上下するよう、案内部４０に挿着されている。なお、止水板３１の下部に設けられた拡幅された部分３２は必須の構成ではなく、止水板３１はその上下方向において、同じ横断面とすることもできる。   The water stop unit 30 includes a water stop plate 31, a top plate 33, and a roller 34. The water stop plate 31 is a plate-like member having its wide surface directed in the vertical direction, and buoyancy can be obtained from water by making the inside hollow. Further, the lower part of the water stop plate 31 is widened except for a portion where the roller 34 is provided, and has a substantially inverted T-shaped cross section. The widened portion 32 also has a hollow structure, and buoyancy with respect to water can be obtained also in the portion. The top plate 33 is provided on the upper surface of the water stop plate 31 and is configured to have the same height as the uppermost upper surface 15 of the housing 11 when the water stop plate 31 is lowered. A plurality of rollers 34 are provided at both ends of the water stop plate 31 in the longitudinal direction. When water is stored in the housing 11 or drained after storage, the water stop plate 31 smoothly moves up and down. It is inserted in the guide part 40 so that it may do. In addition, the widened part 32 provided in the lower part of the water stop board 31 is not an essential structure, and the water stop board 31 can also be made into the same cross section in the up-down direction.

案内部４０は、筐体１１の長手方向の両端部の内部から上方に向かって、止水部３０の可動範囲において設けられるもので、出入口５０の側壁５２に固定されるとともに、横断面略Ｃ字状をなしている。そして、その内側に上記のローラ３４が挿着され滑動することで、止水部３０が案内部４０に沿って上下可能となる。   The guide part 40 is provided in the movable range of the water stop part 30 upward from the inside of both ends in the longitudinal direction of the housing 11, and is fixed to the side wall 52 of the entrance / exit 50, and has a substantially transverse cross section of C. It has a letter shape. Then, the water stop portion 30 can be moved up and down along the guide portion 40 by inserting and sliding the roller 34 inside.

次に、以上説明した各構成要素の機能を踏まえ、図２及び図３を参照しながら、本実施形態の止水ユニット１の動作を説明する。なお、図３において、案内部４０は図２同様に破線で示してある。   Next, based on the function of each component described above, the operation of the water stop unit 1 of the present embodiment will be described with reference to FIGS. 2 and 3. In FIG. 3, the guide part 40 is indicated by a broken line as in FIG.

図２に示すように、平常時は通路面ＧＬには水がなく、筐体１１の内部にも水は貯留されず、止水部３０はその自重によって下降している。そして、天板３３の縁が筐体１１の上面１５と係合し、天板３３と筐体１１の上面１５とは同じ高さとなっている。   As shown in FIG. 2, there is no water on the passage surface GL during normal times, no water is stored inside the housing 11, and the water stop 30 is lowered by its own weight. The edge of the top plate 33 engages with the upper surface 15 of the housing 11, and the top plate 33 and the upper surface 15 of the housing 11 are at the same height.

次に、図３に示すように、集中豪雨等による洪水によって、通路面ＧＬに水Ｗが溢れ、その水面が通路面より所定の高さに設けられた開口部２０に達すると、開口部２０より筐体１１の内部に水Ｗが流入する（図中矢印ａ１）。このとき、排水部２１からも排水されるが（図中矢印ａ２）、上述のとおり排水部２１から排水される量より開口部２０から流入する水Ｗの量が多く、筐体１１の内部に水Ｗが貯留される。   Next, as shown in FIG. 3, when the water W overflows the passage surface GL due to flooding due to torrential rain or the like, and the water surface reaches the opening 20 provided at a predetermined height from the passage surface, the opening 20 Thus, the water W flows into the housing 11 (arrow a1 in the figure). At this time, water is also drained from the drainage part 21 (arrow a2 in the figure), but the amount of water W flowing from the opening 20 is larger than the quantity drained from the drainage part 21 as described above, and the inside of the housing 11 Water W is stored.

すると、止水板３１はその内部が中空となっているため、筐体１１の内部に貯留された水Ｗから浮力を得ることができ、案内部４０に沿って上昇し、筐体１１の上面１５から突出する。そして、出入口５０の周囲の側壁５２と止水部３０とで出入口５０を塞ぎ、地下施設等への水Ｗの浸入を防止する。また、止水板３１は、その下部が拡幅されているため、より強い浮力を得ることができ、その殆どを筐体１１の上面１５より突出させることができる。また、通路面ＧＬに溢れた水Ｗが開口部２０の高さに達しないときは、筐体１１そのもので水Ｗをせき止めることができる。   Then, since the inside of the water stop plate 31 is hollow, buoyancy can be obtained from the water W stored in the inside of the housing 11, and the water stopping plate 31 rises along the guide portion 40, and the upper surface of the housing 11. 15 protrudes. And the side wall 52 around the entrance / exit 50 and the water stop part 30 block | close the entrance / exit 50, and the intrusion of the water W to an underground facility etc. is prevented. Moreover, since the lower part of the water stop plate 31 is widened, stronger buoyancy can be obtained, and most of the water stop plate 31 can protrude from the upper surface 15 of the housing 11. Further, when the water W overflowing the passage surface GL does not reach the height of the opening 20, the water W can be blocked by the casing 11 itself.

次に、通路面ＧＬの水が引くと、開口部２０から水が流入しなくなり、筐体１１の内部に貯留された水は排水部２１から排水される。そして、止水部３０も筐体１１の内部の水位の低下にあわせて下降し、図２に示す状態となる。   Next, when the water on the passage surface GL is drawn, the water does not flow from the opening 20, and the water stored in the housing 11 is drained from the drainage portion 21. And the water stop part 30 also falls according to the fall of the water level inside the housing | casing 11, and will be in the state shown in FIG.

次に、図４〜図６を参照して、他の実施形態に係る止水ユニットを説明する。図４は筐体が箱形に構成された止水ユニット２を示す図、図５は筐体の一方がスロープ状に構成された止水ユニット３を示す図、図６は筐体の両側がスロープ状に構成された止水ユニット４を示す図である。なお、上述の実施形態と機能が同じ構成要素については、同じ符号を付して説明を省略する。   Next, with reference to FIGS. 4-6, the water stop unit which concerns on other embodiment is demonstrated. FIG. 4 is a view showing the water stop unit 2 having a box-shaped housing, FIG. 5 is a view showing the water stop unit 3 having one of the cases formed in a slope shape, and FIG. It is a figure which shows the water stop unit 4 comprised by the slope shape. In addition, about the component with the same function as the above-mentioned embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

図４に示す止水ユニット２は、筐体１２が箱形をなしている。このため、高さ寸法が大きな止水ユニットを設置できない場所等に好適である。また、開口部２０が通路面ＧＬと略同じ高さに設けられており、排水部を備えない。このため、開口部２０を通じて水の流入（図中矢印ａ３）と排水（図中矢印ａ４）が行なわれる。   As for the water stop unit 2 shown in FIG. 4, the housing | casing 12 has comprised the box shape. For this reason, it is suitable for a place where a water stop unit having a large height cannot be installed. Moreover, the opening part 20 is provided in the substantially same height as the channel | path surface GL, and a drainage part is not provided. For this reason, inflow of water (arrow a3 in the figure) and drainage (arrow a4 in the figure) are performed through the opening 20.

図５に示す止水ユニット３は、筐体１３の一方がスロープ状となっている。このため、建物等の入口の段差を解消することができ、通路面ＧＬと床面ＦＬとを滑らかに接続することができる。また、図６に示す止水ユニット４は、筐体１４の両側がスロープ状となっており、車椅子、自転車又は自動車等が通過する場所において好適である。なお、図５及び図６に示す止水ユニットにおいても、開口部２０が通路面ＧＬと略同じ高さに設けられ、排水部を備えず、開口部２０を通じて水の流入と排水が行なわれる。   As for the water stop unit 3 shown in FIG. 5, one side of the housing | casing 13 has a slope shape. For this reason, the level | step difference of entrances, such as a building, can be eliminated, and the channel | path surface GL and the floor surface FL can be connected smoothly. Moreover, the water stop unit 4 shown in FIG. 6 has a slope shape on both sides of the housing 14 and is suitable in a place where a wheelchair, a bicycle, a car, or the like passes. 5 and 6, the opening 20 is provided at substantially the same height as the passage surface GL, does not include a drainage portion, and the inflow and drainage of water is performed through the opening 20.

以上説明したように、上述の実施形態に係る止水ユニットによれば、通路面の上に筐体を設置するため、設置工事において通路面を掘削する必要がなくなり、工期の短縮と工事費の低減を図ることができる。   As described above, according to the water stop unit according to the above-described embodiment, since the housing is installed on the passage surface, it is not necessary to excavate the passage surface in the installation work, which shortens the construction period and reduces the construction cost. Reduction can be achieved.

また、筐体自身でも水をせき止めることができるため、氾濫時に上昇する止水部とあわせて、せき止める水位を高くすることができる。   Moreover, since the water can be dammed by the casing itself, the water level to be dammed can be increased together with the water proof part that rises during flooding.

また、筐体の内部に水を貯留するため、止水板の下部を容易に拡幅することができ、止水板の浮力をより強くすることができ、より高い氾濫水位にも対応することができる。   Moreover, since water is stored inside the housing, the lower part of the water stop plate can be easily widened, the buoyancy of the water stop plate can be made stronger, and it is possible to cope with higher flood water levels. it can.

また、筐体の少なくとも一方をスロープ状とすることで、様々な場所に設置することができる。   Moreover, it can be installed in various places by making at least one of the housings into a slope shape.

なお、上述の止水ユニットは、本発明の例示であり、発明の趣旨を逸脱しない範囲においてその構成を適宜変更できる。   In addition, the above-mentioned water stop unit is an exemplification of the present invention, and the configuration can be appropriately changed without departing from the gist of the invention.
