CUTOFF STEEL MEMBER AND CONSTRUCTION METHOD OF CUTOFF WALL USING THEREOF
To provide cutoff steel members allowing a cutoff wall construction with compensation function for wide and/or narrow spacing and with a stiffer structure.SOLUTION: A cutoff steel member 1 in a H-section steel shape is provided with: an upstream side steel member 2 having a T-shaped steel part consisting of a flange 4 and a web 6; a downstream side steel member 3 having a T-shaped steel part consisting of a flange 5 and a web 7, the web being overlapped with a downstream side of the web of the upstream side steel member, wherein each web has adjustment screw holes, which is a long circular hole to adjust an overlapping amount, within an area where each of webs overlaps to each other when the upstream side steel member and the downstream side steel member are positioned respectively at predetermined maximum separated positions, and the adjustment screw holes are secured with screws through a seal plate perfectly sealing the screw holes. Accordingly, a width is adjusted with an easy method to cutoff.SELECTED DRAWING: Figure 1
【課題】間隔の広狭の補償機能を有し、より堅固な構成の止水壁の建設を可能にする止水鋼材を提供する。【解決手段】Ｈ形鋼の形状の止水鋼材１は、フランジ４及びウェブ６から成るＴ形鋼部分を有する上流側鋼材２と、フランジ５及びウェブ７から成るＴ形鋼部分を有し、ウェブが上流側鋼材のウェブの下流側に重ね合された下流側鋼材３と、を備えており、各ウェブは、重ね合わせの量を調節するための長丸穴であって、上流側鋼材及び下流側鋼材を予め定めた最離位置にした場合に、ウェブ同士が重ね合わされている範囲内にある調節用ねじ穴をそれぞれ有しており、調節用ねじ穴は、当該ねじ穴を完全に塞ぐシール板を介してねじ留めされている、ことを特徴とする。これにより、簡易な方法で幅を調節でき、止水することもできる。【選択図】図１
