The support structure for a circular treatment tank according to the present invention is to assemble a cylindrical wall by sequentially connecting and integrally connecting a plurality of PC blocks each having an arcuate cross section on a perfect circle, and attaching the cylindrical wall to a pile. It is placed on a supported annular continuous underground beam, a bottom plate is created within the cylindrical wall, the peripheral part of the bottom plate is placed on the underground beam, and the cylindrical wall and the ground It is characterized by being connected and fixed to the middle beam with anchor bars.
以下本発明の一実施例を図面にて説明する。 An embodiment of the present invention will be described below with reference to the drawings.
図中１は外側円筒壁で、断面円弧状に形成され
た複数個のPCブロツク２を真円上で順次連接さ

持されている。 This outer cylindrical wall 1 has an annularly continuous underground beam 4.
Placed on top are underground beams 4, waste concrete 5, and cracked stones 6.
It is supported by piles 7 driven into the ground at regular intervals.
８は前記外側円筒壁１内に造成された底版で、
捨コン９と割栗石１０を介して地盤に打設した杭
１１により支持されている。 8 is a bottom plate formed within the outer cylindrical wall 1;
It is supported by piles 11 driven into the ground via waste concrete 9 and cracked stones 10.
この底版８の周辺部は、前記地中梁４上に載置
され、かつ、地中梁４と前記外側円筒壁１にアン
カー筋で連結固定されている。 The peripheral portion of the bottom plate 8 is placed on the underground beam 4 and is connected and fixed to the underground beam 4 and the outer cylindrical wall 1 by anchor bars.
１２は内側円筒壁で、前記外側円筒壁１と同様
に組立てられており、外側円筒壁１と同心に底版
８上に載置されて底版８に設けた環状溝１３に嵌
込まれ、かつ、アンカー筋で固定されている。 Reference numeral 12 denotes an inner cylindrical wall, which is assembled in the same manner as the outer cylindrical wall 1, is placed on the bottom plate 8 concentrically with the outer cylindrical wall 1, and is fitted into an annular groove 13 provided in the bottom plate 8; It is fixed with an anchor.
尚、この内側円筒壁１２は沈澱タンク部として
使用され、該内側円筒壁１２と前記外側円筒壁１

As described above, the present invention comprises a prefabricated cylindrical wall made up of a plurality of PC blocks each having an arcuate cross-section, and a peripheral portion of a bottom slab constructed within the cylindrical wall, which are connected in an annular manner supported by piles. It is placed on a common underground beam and supported in a stable state, and since the cylindrical wall is connected and fixed to the underground beam via the bottom slab, the cylindrical wall remains integrally connected to the bottom slab. However, it can be supported integrally and firmly on underground beams. Therefore, it is possible to reliably prevent damage to the sealing mechanism provided between each PC block on the cylindrical wall and between the cylindrical wall and the bottom plate, making it extremely effective as a support structure for a circular processing tank.
