WATER TREATMENT FACILITY
To increase a mechanical strength of a spiral staircase installed in a water treatment facility, and to obtain a water treatment facility with increased mechanical strength of the spiral staircase installed inside.SOLUTION: Starting from a bottom, tread plates 20A to 20M are attached to a central pillar 10 in a spiral pattern clockwise toward a top when viewed from the bottom. A spiral staircase 1 has a periodic structure in which one period is made up of twelve consecutive tread plates 20. Below the tread plate 20B on an inner surface side of a shaft and on a side of the tread plate 20C, a central pillar support member 30A is provided that extends horizontally and linearly connects the central pillar 10 and the shaft side. A central pillar support member 30B is installed at the tread plate 20D in the same manner as in the case of the tread plate 20B, which is present with the tread plate 20C sandwiched between it and the tread plate 20B. The central pillar 10 is fixed to the inner surface of the shaft by the central pillar support members 30A and 30B.SELECTED DRAWING: Figure 3
【課題】水処理施設内に設置された螺旋階段の機械的強度を高くする。内部に設置された螺旋階段の機械的強度を高めた水処理施設を得る。【解決手段】下側から順に踏板２０Ａ～２０Ｍが心柱１０に対して、下側からみて右回りで上側に向かう螺旋状で装着されている。この螺旋階段１は、連続した１２枚の踏板２０を一周期とした周期的構造を有する。立坑の内面側にある踏板２０Ｂの、下側かつ踏板２０Ｃ側において、心柱１０と立坑側の間を水平に延伸して直線的に連結する心柱支持部材３０Ａが設けられている。心柱支持部材３０Ｂは、踏板２０Ｂとの間に踏板２０Ｃを挟んで存在する踏板２０Ｄにおいて、踏板２０Ｂにおける場合と同様に設置される。心柱１０は、心柱支持部材３０Ａ、３０Ｂによって立坑の内面に固定される。【選択図】図３
