(2)堆砂抑制システム122は、流入ます107と対応する位置にしか配置できない。
(3)千鳥配列とするためのユニット材の配列の制約条件(たとえば、本体フル、本体ハーフ、本体クォータを平面レイアウトに配置する場合の制約条件)を満たすように配置する。具体的な条件は後述する。
その他の制約条件として、例えば、基本形状領域103の大きさ及び段数に応じて、必要最低限の流出ます108の個数などを設定しても良い。これは、基本形状領域103の容積に応じて、流出ます108から流すことができる流量を大きくしておく必要があるからである。また、基本形状領域103の大きさ及び段数に応じて、必要最低限の点検孔122の個数などを設定しても良い。これは、基本形状領域103の容積に応じて、点検箇所や清掃箇所を増やす必要があるからである。
その他、必要に応じて、その他の構成要素の設定情報として入力可能にしても良い。その他の構成要素の設定情報としては、例えば、流入ますや流出ますのパイプ管の径、基礎の設定(砂、砕石、コンプリートなどの配分)、土被り設定(地面12から水槽10までの距離)などが考えられる。
(1)角部が内角90度の場合の組立手順
(2)角部が内角270度の場合の組立手順
(3)点検孔の周囲の組立手順
次に、制御部31は、<1段目(最下段)の上部>において、全ての単位ますに対して、本体フルを下向きに設置する(ステップS202)。
構成要素のID61は、構成要素を一意に識別する番号である。構成要素の種類62は、構成要素の種類に加えて、ユニット材2の種類まで特定可能な情報である。段番号63は、段の番号に加えて、各段の上部又は下部のいずれかまで特定可能な情報である。
第1座標64、第2座標65及び第3座標66は、構成要素の水平方向の位置(2次元座標における位置)を特定可能な情報である。例えば、第1座標64が構成要素の左上座標、第2座標65が構成要素の左下座標、第3座標66が構成要素の右上座標とすれば、構成要素の水平方向の位置が特定される。
次に、制御部31は、<i段目(中間段)の上部>において、全ての単位ますに対して、本体フルを下向きに設置し、ステップS204に戻る(ステップS206)。
次に、制御部31は、<最上段の上部>において、全ての単位ますに対して、本体フルを下向きに設置し、処理を終了する(ステップS208)。特に、<最上段の上部>には、「本体フル突起なし」を設置する。
角部が内角90度の場合、レイアウト設計装置30は、以上のように、ユニット材2のレイアウト計算を行う。
図17(a)に示すように、下部の角部に、1個の本体クォータB26b、2個の本体クォータA25b、25cが設置される。次に、図17(b)に示すように、下部の端部に、本体ハーフ24i、24jが設置される。次に、図17(c)に示すように、下部の内部に、本体フル21s~21wが設置される。次に、図17(d)に示すように、上部の全ての単位ますに、本体フル21x~21aeが下向きに設置される。
図18(a)に示すように、下部の角部に、1個の本体クォータA25d、2個の本体クォータB25c、25dが設置される。次に、図18(b)に示すように、下部の端部に、本体ハーフ24k、24lが設置される。次に、図18(c)に示すように、下部の内部に、本体フル21af~21ajが設置される。次に、図18(d)に示すように、上部の全ての単位ますに、本体フル21ak~21arが下向きに設置される。
角部が内角270度の場合、レイアウト設計装置30は、以上のように、ユニット材2のレイアウト計算を行う。
次に、制御部31は、<i段目の上部>において、点検孔の周囲4箇所に、2個の本体3/4Aと2個の本体3/4Bを設置する(ステップS302)。
次に、制御部31は、現在が最上段か否か判定し(ステップS303)、最上段でない場合(ステップS303のNo)、S301から繰り返し、最上段の場合(ステップS303のYes)、処理を終了する。
点検孔がある場合、レイアウト設計装置30は、以上のように、ユニット材2のレイアウト計算を行う。
制御部31は、公知の技術によって、一時ファイルのデータを、CADファイル(例えば、dxfファイルなど)に変換する。CADファイルには、各段のユニット材2のレイアウトが含まれる。各段のユニット材2のレイアウトは、実際に施工を行うときの施工管理、進捗管理の情報として用いることができる。
また、制御部31は、例えば、構成要素の単価を示すデータ(例えば、図6に示す構成要素データ50)を用いて、雨水貯留浸透施設1の施工に必要な部材コストの計算を行う。
前述の説明では、千鳥配置によって嵌合されるユニット材のレイアウト計算を行うものとしたが、本発明のレイアウト設計装置30は、その他のユニット材のレイアウト計算も行うことができる。例えば、各段の上部のユニット材及び下部のユニット材が1対1に上下対向するような場合にも適用可能である。この場合、レイアウト設計装置30は、単に、1個の単位ますに対して、単位ますと同じ面積を有するユニット材を1個ずつ配置していくことになる。尚、このようなユニット材の場合、ユニット材同士をつなぐ継ぎ手が必要となる。このような配置は、対向配置と呼ばれる。一般には、土圧やせん断応力の問題から、対向配置を用いることは少ない。但し、土圧が少ない環境で、底が浅い水槽10の場合、対向配置を用いることもある。対向配置の場合、本体フル21のユニット材のみで雨水貯留浸透施設1を形成することができる。対向配置の場合、図17の内容と異なり、下側の本体フル21のユニット材と本体フル21の上側のユニット材とが1対1に対向するように配置することができる。もちろん、平面レイアウトの形状によっては、例えば1辺だけに本体ハーフ24を配置するなど、本体フル21以外のユニット材を用いても良い。
次に、図22を参照しながら、本発明の実施形態の変形例1について説明する。雨水貯留浸透施設1のレイアウト設計では、土圧等の荷重によって生じる水平方向のせん断応力に対して、雨水貯留浸透施設1の強度を担保するために、本体フル21、本体ハーフ24、本体クォータA25及び本体クォータB26を組み合わせて、千鳥配置の構造体を構築する。この際、敷地形状に合わせて所定の容量の水槽10を設計するために、様々な基本形状領域103の平面レイアウトが考えられる。
・点検孔7及び堆砂抑制システム8は、平面レイアウト71(基本形状領域103)の境界からT(T=1、1.5、又は2)個の単位ます分以上離れた位置に配置する。
・堆砂抑制システム8は、流入管15と対応する位置に配置する。
・平面レイアウト71(基本形状領域103)は、敷地形状70の内部に配置する。
・平面レイアウト71は、水槽10が所定の容量となるように設計する。
・平面レイアウト71(基本形状領域103)の角部には、本体クォータA25又は本体クォータB26を配置する。
・平面レイアウト71(基本形状領域103)の端部には、本体ハーフ24を配置する。
・平面レイアウト71(基本形状領域103)の内部には、本体フル21を配置する。
・敷地形状70の境界から平面レイアウト71の境界までの距離は、少なくとも所定の距離(例えば、2~3m)以上とする。
・敷地に隣接して、土手や建築物が存在する場合には、それらによって土圧が増加することを考慮し、敷地形状70の境界から平面レイアウト71の境界までの距離は、更に土圧の影響を考慮した距離とする。
次に、図23~図25を参照しながら、本発明の実施形態の変形例2について説明する。雨水貯留浸透施設1のレイアウト設計では、雨水貯留浸透施設1の強度を担保するために、以下に例示する水槽10に加わる荷重を考慮して、千鳥配置の構造体を構築する。
・土被り:鉛直方向死荷重。鉛直方向長期荷重に対する照査。
・水槽底面深さ:水平土圧。水平方向短期荷重及び長期荷重に対する照査。
・水槽上部の車両荷重規格:鉛直方向活荷重。鉛直方向短期荷重に対する照査。
次に、本発明の実施形態の変形例3について説明する。雨水貯留浸透施設1の施工作業では、現場の条件によって作業人工数が変わる。ここで、現場の条件とは、資材置き場のスペース、トラック搬送ルート、道幅、使用可能重機(ユニック車又はラフタークレーン等)、掘削孔形状、水槽形状(平面形状×高さ)等である。そこで、変形例3では、レイアウト設計装置30は、前述の現場の条件が入力されると、掘削に必要な作業人工数や組み立てに必要な作業人工数計算しさらに、水槽組立工事期間を計算し、出力する。
次に、本発明の実施形態の変形例4について説明する。雨水貯留浸透施設1の施工作業では、予備部材を確保しておく必要がある。そこで、変形例4では、レイアウト設計装置30は、平面レイアウトの設計が終了し、構成要素ごとの必要個数や水槽組立工事期間等が決まると、現場に納入すべき予備部材の種類と数量を計算し、出力する。
