【００２２】
【発明の実施の形態】
次に本発明を図示の実施形態に基づいて詳細に説明する。
【００２３】
図１〜図４は、第１実施形態に係る水域構造物を示すものである。まず、下側の所定箇所に、Ｔ字状の鋼製継手１と嵌合溝５を有する鋼製パイプからなる継手１ａ、１ｂを備えた鋼管矢板からなる多数の上部透過壁体構成部材２を、前記各継手１ａ、１ｂを相互に噛み合わせた状態で支持地盤層（図示を省略する）内に到達するまで水底地盤１３に打設する。これにより上側に通水用スリット３を有する上部透過壁体４が構成される。上側の通水用スリット３は、継手１ａ、１ｂの上端（イ）を上部透過壁体構成部材２の頭部が連結されるコンクリート製上部工１２における構造物延長方向連結材３０の下面（ロ）よりも所定寸法Ｌだけ下げることで、鋼管矢板本体の間に形成される。また、通水用スリット３は各上部透過壁体構成部材２を繋ぐ全ての継手１ａ、１ｂに設けてもよいし、１個あるいは複数の継手毎に間隔を置いて設けても何れでもよい。また、所定寸法Ｌは各継手毎に異なってもよい。
【００２４】
前記上部透過壁体４に対向して所定間隔を隔てた後方位置には、不透過壁体８が構成される。不透過壁体８は、上端まで伸びるＴ字状の鋼製継手１と嵌合溝５を有する鋼製パイプからなる継手５ａ、５ｂを備えた鋼管矢板からなる多数の上部不透過壁体構成部材６を、前記継手５ａ、５ｂを相互に噛み合わせた状態で、支持地盤層（図示を省略する）内に到達するまで水底地盤１３に打設することで構成される。上部不透過壁体構成部材６の上端は、コンクリート製上部工１２における構造物延長方向連結材３１に結合されている。
【００２５】
前記上部不透過壁体構成部材６に対向して所定間隔を隔てた後方位置において、構造物延長方向に所定間隔で鋼管製の後方杭１７が、支持地盤層（図示を省略する）内に到達するまで水底地盤１３に打設されている。後方杭１７の上端は、コンクリート製上部工１２における構造物延長方向連結材３２の上方結合部Ｂに結合されている。コンクリート製上部工１２は、上部透過壁体構成部材２と上部不透過壁体構成部材６と後方杭１７の頭部を連結するＨ型鋼からなる上部鋼製梁１１にコンクリートを打設してなる鉄骨鉄筋コンクリート製または鉄筋コンクリート製で構築するもので、上部鋼製梁１１は、防食が施されていても非防食であっても構わない。
【００２６】
前記不透過壁体８の上部から水底地盤１３に向かって斜め下向きに延長する多数の斜材１４が構造物延長方向に適宜の間隔を隔てて配置され、前記斜材の下端部には、杭挿通用下部筒体１５が連結され、この下部筒体１５に後方杭１７が挿通されている。図４に示すように、前記下部筒体１５で覆われる後方杭１７の外周面に複数のずれ止め用の突起１６を固着し、杭挿通用下部筒体１５の内面には、適宜間隔でずれ止め用の突起１６ａを設けると共に、下部筒体４の下端内周部にシーリング２４を配置し、グラウト注入用ホースを介して、後方杭１７と下部筒体１５とにより形成された空間部には、モルタル等の経時硬化性材料１８が充填され、この下部筒体１５は、前記後方杭１７の中間部に結合され格点１９を形成している。前記斜材１４の上端部は、上方結合部Ａに結合されている。
【００２７】
このように、斜材１４を設けることで構造体の水平方向の耐荷機能が向上する。下部筒体１５と斜材１４は裏埋材２０の中に位置している。斜材１４の上端部と不透過壁体構成部材６の上端部は、上方結合部Ａにおいて連結されている。
【００２８】
前記不透過壁体８の背面側は裏埋材２０が適宜高さまで充填されていると共に、上部透過壁体４と不透過壁体８の間には、適宜高さまで土砂等の中詰材２１が充填されて、この土砂等の中詰材２１の上側でかつ上部透過壁体４と不透過壁体８の間に遊水室２２が形成されている。土砂等の中詰材２１の上面には、表面保護層２３が設けられていて、この表面保護層２３は、水平な面であり、前部の継手１ａ、１ｂの上端（イ）は表面保護層２３と略同一レベルか若干高い位置に設けられる。なお、この表面保護層２３（土砂等の中詰材２１の表面）は、後方から前方に向かって低くなるように傾斜した斜面、あるいは、斜面と水平面を組合わせた形状等の任意形状であっても構わない。
【００２９】
前述のように構成される前部の透過壁体４と後部の不透過壁体８の間で土砂等の中詰材２１の上に設けた遊水室２２には、海水が透過壁体４の上部の通水用スリット３を通って出入し、このとき波の勢いが減衰されて消波効果が発揮される。２５は海水面である。
【００３０】
なお、前記通水用スリット３の幅をＤ１とし、かつ上部透過壁体構成部材２の配置間隔をＤ２とすると、Ｄ１／Ｄ２は約５〜３５％に設定され、好ましくは１０〜２０％である。
【００３１】

【００３７】
図１０は第７実施形態を示し、この実施形態では、上部透過壁体構成部材２と上部不透過壁体構成部材６と後方杭１７の頭部を連結する鋼製梁１１は使用されていないと共に、上部透過壁体構成部材２と上部不透過壁体構成部材６の間を結合する断面方向連結材ＣＡは、鉄骨不使用の、鉄筋コンクリート製であり、また、後方杭１７と上部不透過壁体構成部材６の間を結合する断面方向連結材ＡＢが省略されている例が示されている。また、後方杭１７の頭部の構造物延長方向連結材も省略されている。

【００４０】
以上の実施形態により本発明を説明してきたが、本発明の請求の範囲はこれらの実施形態に限定されるものではない。例えば、図１２に示すように、上部透過壁体４の継手１ａ、１ｂを海水面付近にも設けて、通水用スリット３が水没しているような構成としてもよい。
