(See Figures 1 and 2) When constructing the treatment tank 1 having such a configuration, first, a plurality of prefabricated outer wall blocks 7 are tension-connected using the connecting PC steel material 6 provided therein. The blocks are assembled into a circular shape on the foundation 8, and prestressed in the circumferential direction on the outer circumferential surface of each of the circular prefabricated blocks 7 to join them together to form the outer wall 4. (See FIGS. 3 to 8) Prestress on the outer peripheral surface is achieved by providing a fixing rib portion 7b formed by connecting upper and lower rib portions 7a to each predetermined number of prefabricated blocks 7. At the same time, prestressing PC steel material 9 wound around the outer peripheral surface of a plurality of prefabricated blocks 7 is tension-fixed to this fixing rib portion 7b.

。Also, the outer wall 4 formed by the plurality of prefabricated blocks 7
In order to apply prestress to the outer peripheral surface of the PC steel members 9 and integrate them, two (three) PC steel members 9 with a circumference length of about 172 (approximately 173 circumference length is also acceptable) are 1/2 (1/2 3) For each outer circumferential surface, it is wound around the entire length of the outer circumferential surface of the outer wall 4 and provided in multiple stages from the lower end of the outer wall 4, and is formed on the prefabricated block 7 for the outer wall at the end contact position of these two (three) PC steel materials 9. This is done by gripping and fixing the ends of each PC steel material 9 to the fixing rib portion 7b. Note that this grip fixing position is 60° for each stage (
90°) differently anchored. (Figure 8, 1st
(See Figures 0 and 11) Next, concrete for forming the bottom slab 10 is placed on the foundation 8 inside the outer wall 4.

0 through an anchor member 11. (See Figures 3 and 5) Next, a plurality of inner wall prefabricated blocks 2a are assembled into a circular shape by connecting the bottom plate 10 and anchor bars 13 using the groove 12 formed in the center of the bottom plate 10. At the same time, the inner wall 2 is formed by connecting and joining the inner and outer parts using connecting fittings 14 and bolts and nuts (not shown) provided on each member. (See Figures 12 and 13) Meanwhile, joint material is injected into the joint surfaces of each prefabricated block 4a for external walls, the joint surfaces of each prefab block 4a for external walls, the joint surfaces of each prefab block 2a for internal walls, and the outer wall. The corners of the prefabricated block 4a for the inner wall and the bottom plate 11 are filled with sealing material, and the inner and outer corners of the prefab block 2a for the inner wall and the bottom plate 11 are filled with mortar. The construction work has been completed. (Refer to FIG. 14) Note that the anchor member and anchor bar used in this embodiment are made of anodized egalvanized round steel, stainless steel round steel, or the like.
