GROIN WORK
To enable workers to perform construction easily in a river.SOLUTION: A groin work 1 comprises a first structure 11 that is a wall body disposed upstream of a target region S where a water flow of a river is to be decelerated, and a second structure 12 that is a wall body disposed downstream of the target region S and away from the first structure 11. The first structure 11 includes a first wall body 111 having an upstream part 1111 that approaches the left bank of the river as it goes downstream, and a second wall body 112 having an upstream part 1121 that contacts the first wall body 111 on the upstream side and approaches the right bank of the river as it goes downstream. The second structure 12 includes a third wall body 121 having a downstream part 1211 that approaches the left bank of the river as it goes upstream, and a fourth wall body 122 having a downstream part 1221 that contacts the third wall body 121 on the downstream side and approaches the right bank of the river as it goes upstream.SELECTED DRAWING: Figure 1
【課題】作業者が河川内における工事を容易に行うことを可能とする。【解決手段】水制工１は、河川の水流を減勢させたい対象領域Ｓの上流側に配置された壁体である第１の構造物１１と、対象領域Ｓの下流側に第１の構造物１１から分離されて配置された壁体である第２の構造物１２を備える。第１の構造物１１は、下流に向かうに従い河川の左岸に近づく上流側部分１１１１を有する第１の壁体１１１と、第１の壁体１１１と上流側において接し下流に向かうに従い河川の右岸に近づく上流側部分１１２１を有する第２の壁体１１２とを有する。第２の構造物１２は、上流に向かうに従い河川の左岸に近づく下流側部分１２１１を有する第３の壁体１２１と、第３の壁体１２１と下流側において接し上流に向かうに従い河川の右岸に近づく下流側部分１２２１を有する第４の壁体１２２とを有する。【選択図】図１
