Therefore, it is necessary to first construct the side wall under the ground. The construction of this side wall is performed as follows.
(1) The first side wall, which is obtained by dividing the entire side wall into about 5 to 10 steps in the height direction according to the height of the underground tank, is constructed on the ground. (2) Excavate the ground immediately below the first stage side wall and sink it by the height of the side wall. (3) Reinforced concrete is constructed just above the first-stage side wall, and the second-stage side wall is constructed on the ground. (4) Excavate the ground immediately below the first stage side wall and sink it by the height of the second stage side wall. (5) Thereafter, the construction and sinking of the upper side wall on the ground portion are repeated, so that the side wall having a predetermined height is built at a predetermined position. When the side wall is constructed, a suitable number of guide rails for guiding a slab to be constructed later are attached to the inner surface thereof in the vertical direction.

In order to excavate the ground immediately below the side wall, it is necessary to provide an excavating means and an earth discharging means at the lower end of the side wall of the first stage. A typical example of this excavating means is in the vertical direction of the side wall. A water jet pipe communicating therewith is mentioned, and a typical example of the earth discharging means is a mud pipe communicating vertically in the side wall. A predetermined number of these pipes are buried along the circumferential direction when the side wall is constructed, and are connected at the time of splicing, and open to the lower end of the side wall and the ground. Therefore, excavation by injection of high-pressure water and earth removal by suction of mud slurry can be easily performed by operation from the ground portion.
