To prevent floating of a water passage skeleton and inclination of side walls, in a water passage where a high groundwater level is assumed.SOLUTION: A water passage skeleton 11 includes a bottom slab 12 and a pair of side walls 13, and at least at a width end part of the bottom slab 12 and the side walls 13, a plurality of width end portions of bottom slab parts 22 and side wall parts 23 of a precast concrete block 21 for a water passage are continued. At an installation place where a groundwater level becomes equal to or higher than 1/2 of the height of the side walls 13, the water passage skeleton 11 is installed. At both sides of the side walls 13, backfilling materials are provided. At a predetermined position equal to or lower than 1/2 of the height of the side wall parts 23, a plurality of knock-out parts 26 formed by reducing the thickness of the side wall parts 23 for forming a lower stage weep hole 27 by punching out are provided at predetermined pitches in the passage length direction.SELECTED DRAWING: Figure 2
【課題】高い地下水位が想定される水路水路において、水路躯体の浮上や側壁の傾斜を防止する。【解決手段】水路躯体１１は底版１２と一対の側壁１３とを含み、少なくとも底版１２の幅端部及び側壁１３はプレキャストコンクリート製の水路用ブロック２１の底版部２２の幅端部分及び側壁部２３が複数連なったものである。地位水位が側壁１３の１／２高さ以上となることがある設置場所に、水路躯体１１が設置されている。側壁１３の両脇には埋め戻し材がある。側壁部２３の１／２高さ以下の所定位置に、打ち抜いて下段ウィープホール２７を形成するための、側壁部２３の厚さを減じてなるノックアウト部２６が、路長方向に所定ピッチで複数設けられている。【選択図】図２
