Abstract
Description
本発明は、土木用資材であるテーブル状部材を用いた雨水流出抑制用貯留施設内の砂泥蓄積を軽減させる技術に属する。 The present invention belongs to a technique for reducing accumulation of sand and mud in a rainwater outflow suppression storage facility using a table-like member that is a civil engineering material.
一時的に雨水を貯留し、徐々に流出させる雨水流出抑制施設を構築する土木用資材として平盤部と平盤部に開口する脚部からなるを設けたテーブル状部材が使われている。平盤部が主としてリブで形成されているためと使用時平盤部が槽底面に接するように配置されるため、上記リブ内に堆積した砂泥は除去するのが困難である。
テーブル状部材を利用して構築された貯留槽内に沈積した砂泥を除去するため水槽底面に傾斜を付ける(たとえば、特開2008−38339、特開2007-332693、特開2007−198044、特開2007−198043)、あるいはテーブル状部材の平盤部上面を滑らかにして砂泥が流出しやすくする(特開2009−57695)などの提案を行ってきた。
As a civil engineering material for constructing a rainwater outflow control facility for temporarily storing rainwater and gradually discharging it, a table-like member provided with a flat plate portion and a leg portion opening to the flat plate portion is used. Since the flat plate portion is mainly formed of ribs and the flat plate portion is arranged so as to be in contact with the tank bottom surface during use, it is difficult to remove sand mud accumulated in the ribs.
In order to remove sand mud deposited in a storage tank constructed using a table-like member, the bottom of the water tank is inclined (for example, Japanese Patent Application Laid-Open No. 2008-38339, Japanese Patent Application Publication No. 2007-332893, Japanese Patent Application Laid-Open No. 2007-198044, Have been proposed such as open 2007-198043), or smoothing the upper surface of the flat plate portion of the table-like member to facilitate the outflow of sand mud (Japanese Patent Laid-Open No. 2009-57695).
テーブル状部材を利用して構築される貯留槽底部に沈積する砂泥を除去しやすくする貯留槽の構造を提案する。 The structure of the storage tank which makes it easy to remove sand mud deposited on the bottom of the storage tank constructed using a table-like member is proposed.
本第1の発明は、平盤部と平盤部に開口する脚部からなるテーブル状部材を2個その脚部底面を対向させてユニットを形成し、当該ユニットを上下左右に配列して得られる貯留空間を遮水シートで覆って得られる貯留槽であって、貯留槽最下部に存在するユニットの平盤部の下部に、平盤部より小さな水を流通させないブロックを配設させた貯留槽である。
貯留槽底と貯留槽底に接するユニットの平盤部の間に平盤部より小さなブロックを配置し、貯留槽底に水が直接流れるようにした。
本第2の発明は、上記発明記載のブロックの配設位置をテーブル状部材脚部部分の下部に配設させた貯留槽である。
上記手段に合わせテーブル状部材脚部にかかわる荷重をブロックで受けるようにした。
The first invention is obtained by forming a unit by arranging two table-like members consisting of a flat plate portion and legs that open to the flat plate portion, with the bottom surfaces of the leg portions facing each other, and arranging the units vertically and horizontally. A storage tank obtained by covering the storage space to be covered with a water-impervious sheet, wherein a block that does not allow water to flow smaller than the flat plate portion is disposed below the flat plate portion of the unit existing at the bottom of the storage tank. It is a tank.
Between the storage tank bottom and the flat plate part of the unit in contact with the storage tank bottom, a block smaller than the flat plate part is arranged so that water flows directly to the storage tank bottom.
The second invention is a storage tank in which the arrangement position of the block described in the above invention is arranged below the leg portion of the table-like member.
In accordance with the above means, the load related to the table-like member leg is received by the block.
本第1の発明は、平盤部と平盤部に開口する脚部からなるテーブル状部材を2個その脚部底面を対向させてユニットを形成し、当該ユニットを上下左右に配列して得られる貯留空間を遮水シートで覆って得られる貯留槽であって、貯留槽最下部に存在するユニットの平盤部の下部に、平盤部より小さな水を流通させないブロックを配設させた貯留槽である。
そのため、ブロック周囲の貯留槽底に直接水が流れるため槽底に沈積した砂泥が流れやすくなる。
本第2の発明は、上記発明記載のブロックの配設位置をテーブル状部材脚部部分の下部に配設させた貯留槽である。
そのため、テーブル状部材の脚部に垂直強度を高める目的でコンクリート製の芯などを挿入する場合、上記効果に合わせ脚部に挿入した芯に起因する荷重に耐えることが可能となる。
The first invention is obtained by forming a unit by arranging two table-like members consisting of a flat plate portion and legs that open to the flat plate portion, with the bottom surfaces of the leg portions facing each other, and arranging the units vertically and horizontally. A storage tank obtained by covering the storage space to be covered with a water-impervious sheet, wherein a block that does not allow water to flow smaller than the flat plate portion is disposed below the flat plate portion of the unit existing at the bottom of the storage tank. It is a tank.
Therefore, since water flows directly to the storage tank bottom around the block, sand mud deposited on the tank bottom can easily flow.
The second invention is a storage tank in which the arrangement position of the block described in the above invention is arranged below the leg portion of the table-like member.
Therefore, when a concrete core or the like is inserted into the leg portion of the table-like member for the purpose of increasing the vertical strength, it becomes possible to withstand the load caused by the core inserted into the leg portion in accordance with the above effects.
以下、本発明を図により詳細に説明する。
図1に示す通り、本発明の貯留槽構築に用いられるテーブル状部材は平盤部と平盤部に開口する脚部から構成される。
平盤部は貯留する雨水が上下に流れ下るよう複数の孔が設けられている。形状は正方形、長方形、あるいはそれらの端部を切り欠いた形状であり、全体として密着して配置できる形状であれば良い。脚部はテーパを設けた筒状系を有し、その断面は円形、多角形、梅鉢形など任意に選ぶことができる。平盤部に設ける脚部の位置、個数も任意に設定可能である。
テーブル状部材は、一般には図2に示すように、その脚部底面を対向させた状態で接続したユニットとして使用される。
Hereinafter, the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, the table-like member used for construction of the storage tank of the present invention is composed of a flat plate portion and a leg portion that opens to the flat plate portion.
The flat plate portion is provided with a plurality of holes so that the rainwater stored can flow up and down. The shape may be a square, a rectangle, or a shape in which an end portion thereof is cut out, and may be any shape that can be disposed in close contact as a whole. The leg portion has a cylindrical system with a taper, and the cross section can be arbitrarily selected from a circular shape, a polygonal shape, a plum shape, and the like. The position and number of legs provided on the flat board can also be set arbitrarily.
As shown in FIG. 2, the table-like member is generally used as a unit connected with its leg bottoms facing each other.
図3は、本発明の貯留槽底部を示す概念図である。
図に示したとおり、ユニットの平盤部が貯留槽底部に直接接しないよう平盤部と水槽底部に設けたシートとの間にブロックが配置されている。ブロックの大きさは平盤部より小さくブロック間に隙間が形成される。その隙間を利用して貯留槽底に沈積した砂泥を洗い流せるようにしたものである。洗い流された砂泥は別途貯留槽内に設けた溝、ピットなどの従来手段により除去することができる。尚ここにいう平盤部は図に示すようにユニット1個に対応するものではなく複数のユニットの平盤部を合わせたものを含むものである。すなわち直線状にユニットの平盤部を2以上並べてそれらに対応する多きさのブロックを使用するあるいはユニットの平盤部を4以上を並べて正方形あるいは直方形を形成しそれらに対応する多きさのブロックを使用することも含むものである。
FIG. 3 is a conceptual diagram showing the bottom of the storage tank of the present invention.
As shown in the figure, a block is arranged between the flat plate portion and the sheet provided at the bottom of the water tank so that the flat plate portion of the unit does not directly contact the bottom of the storage tank. The size of the block is smaller than that of the flat plate, and a gap is formed between the blocks. By using the gap, sand mud deposited on the bottom of the storage tank can be washed away. Washed sand mud can be removed by conventional means such as grooves and pits separately provided in the storage tank. In addition, the flat board part here does not respond | correspond to one unit as shown in the figure, but includes what combined the flat board part of several units. That is, two or more flat plate portions of the unit are arranged in a straight line, and a block having a large size corresponding to them is used, or four or more flat plate portions of the unit are arranged to form a square or a rectangular shape and a large number of blocks corresponding to them. Including the use of.
ブロックは、図ではその平面が平盤部より小さな正方形であり、貯留槽内の水がその内部に流通しない形状であればよい。正方形に限らず円形・多角形など適宜使用できる、周囲に砂泥が滞らない形状とすることが好ましい。 In the figure, the block has a square shape whose plane is smaller than that of the flat plate portion, and any shape may be used as long as the water in the storage tank does not flow therethrough. It is preferable to use a shape that is not limited to a square but can be used as appropriate, such as a circle or a polygon, and that does not stagnate with sand and mud.
図4は、ブロックをテーブル状部材の脚部に相当する部分に配設した例を示している。これは、脚部空洞内にユニットにかかる鉛直荷重に耐える目的でコンクリート芯などを挿入した場合に上記砂泥流出目的と合わせ、コンクリート芯に起因する荷重を受ける目的をも果たすものである。コンクリート芯は上から下まで一本貫通するものであっても、各脚部毎に挿入してもよい。
図では、特に芯は示してないが、各脚部に対応してブロックを配設している状態を示している。また、複数の脚部に対応して配設することも可能である。
FIG. 4 shows an example in which the blocks are arranged at portions corresponding to the leg portions of the table-like member. This also fulfills the purpose of receiving the load caused by the concrete core when the concrete core or the like is inserted into the leg cavity for the purpose of withstanding the vertical load applied to the unit. Even if the concrete core penetrates from the top to the bottom, it may be inserted for each leg.
In the figure, the core is not particularly shown, but the block is disposed corresponding to each leg. Moreover, it is also possible to arrange | position corresponding to a some leg part.
図5は、テーブル状部材を上述したようユニットとし、上下左右に配列して、貯留空間を形成し、それをシート類で覆い、泥だめ枡、オリフィス枡など付帯設備を設けた雨水流出抑制施設である貯留槽の例を示している。
