LEVEE BODY DRILLING METHOD AND DISCHARGE PIPING CONSTRUCTION METHOD
To propose a levee body drilling method and discharge piping construction method that can reduce work time and costs when constructing.SOLUTION: The levee body drilling method includes a drilling step for forming a bottomed vertical hole 3 by drilling a levee body 1, and a penetration step for opening the vertical hole 3 by drilling the bottom of the vertical hole 3. The drilling step includes work for starting to drill the levee body 1 from the downstream side and separating the formation area of the vertical hole 3 into a plurality of blocks, and work for removing the blocks from the downstream side of the levee body 1. The penetration step is performed when the dam water level is lowered.SELECTED DRAWING: Figure 1
【課題】施工時の手間および費用の低減化を可能とした堤体削孔工法および放流管施工方法を提案する。【解決手段】堤体１を削孔して有底の横孔３を形成する削孔工程と、横孔３の底部を削孔して横孔３を貫通させる貫通工程とを備える堤体削孔工法である。削孔工程は、堤体１を下流側から切削して、横孔３の形成領域を複数のブロックに分割する作業と、ブロックを堤体１の下流側から抜き出す作業とを備えている。貫通工程はダム水位の低下時に行う。【選択図】図１
