TIMBERING STRUCTURE OF CIRCULAR VERTICAL SHAFT, AND CONSTRUCTION METHOD FOR CIRCULAR VERTICAL SHAFT
PROBLEM TO BE SOLVED: To provide a timbering structure of a circular vertical shaft, which enables the circular vertical shaft to be simply and inexpensively constructed without being restricted by surrounding environments, and a construction method for the circular vertical shaft.SOLUTION: A timbering structure 2 of a circular vertical shaft includes: circular timbering 3 that is arranged inside an earth retaining wall 10; a plurality of jacks 4, 4,... that are interposed between the earth retaining wall 10 and the circular timbering 3; and jack control means 5 for actuating the plurality of jacks 4, 4,.... A construction method for the circular vertical shaft utilizes the timbering structure 2.SELECTED DRAWING: Figure 1
【課題】周囲の環境に制限されることなく、簡易かつ安価に円形立坑を構築することができる円形立坑の支保構造および円形立坑の施工方法を提案する。【解決手段】土留壁１０の内側に配設された円形支保工３と、土留壁１０と円形支保工３との隙間に介設された複数のジャッキ４，４，…と、複数のジャッキ４，４，…を作動させるジャッキ制御手段５とを備える円形立坑の支保構造２およびこの支保構造２を利用した円形立坑の施工方法。【選択図】図１
