In addition, in the city department, a system in which a water storage tank having an artificial water storage space is installed in a ground floor of a building, a park, or a parking lot in order to ensure fireproof water and industrial water, and rainwater can efficiently flow into the water storage tank. Such a water storage tank must be sufficiently resistant to pressure from above because it is used as a parking lot, a park, or the like. Therefore, the filler material is filled in the water storage space to increase the strength, and grit and gravel are usually used as the filler. However, depending on the region, it is difficult to start with such grit and gravel in sufficient quantities. The price has become a high price. Moreover, even in the case of a large number of depressions for storing water, in the case of using gravel and gravel, the amount of water stored should at least reduce the volume fraction of gravel and gravel. In general, in the case where the crushed stone is used as a filler, the water storage rate is about 40% as compared with the overall volume of the depression, and the remaining 60% is occupied by the gravel. Patent Document 1 discloses a water storage method in which a water storage tank in which a block filler is disposed in a water storage space surrounded by a waterproof sheet is disposed, and a waterproof sheet is formed in advance at a recess. It is a layered waterproof molded body, and thereafter, a filler is placed in the waterproof molded body. Further, Patent Document 2 discloses a water storage tank or the like which is characterized in that a base having a sloped surface is provided in a water storage tank in which a filler is disposed in a water storage space in which a waterproof sheet is placed on a base formed in a concave shape. With the bottom surface, the water storage space of the waterproof sheet is applied and the square body filling material and the small size filling material are arranged. Further, Patent Document 3 describes a covering body which is used for an underground water storage tank which is formed by liquid-tightly covering a water storage block group made of synthetic resin. The block filling material disclosed in the above-mentioned Patent Documents 1 to 3 can withstand the pressure from the upper side by using a molded body containing a material such as a resin, and sets the water storage rate as compared with the capacity of the entire recess for storing water. More than 90%. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-279724 (Patent Document No. JP-A-2001-79524)

That is, in the present embodiment, the L-shaped corner pieces 52 are disposed on the twelve side portions 25 of the filler 2, respectively. Further, as the size of the L-shaped corner piece 52, for example, the width a is 200 to 1200 mm, the width b is 30 to 60 mm, and the thickness is 2 to 5 mm. Further, the L-shaped corner piece 52 is not necessarily disposed on the side portion 25 of all the filler members 2. In the present embodiment, as the material constituting the three-pronged corner piece 51 and the L-shaped corner piece 52, the same material as the waterproof sheet 3 is used. In other words, as the material constituting the three-pronged corner piece 51 and the L-shaped corner piece 52, a vulcanized rubber type, a thermoplastic elastic system, a polyethylene resin type, an ethylene vinyl acetate resin type, or a vinyl chloride resin type is preferable. It is a polyethylene resin system which is high in strength and excellent in weather resistance. In the present embodiment, the three-pronged corner piece 51 and the L-shaped corner piece 52 are disposed on the side portion 25 and the apex portion 26 of the filler 2 as shown in Fig. 5, and are directly joined to the trigeminal corner piece 51 and the L-shaped corner piece 52. There are waterproof sheets 3. As the joining form of the trifurcated corner piece 51 and the L-shaped corner piece 52 and the waterproof sheet 3, for example, in the case where the waterproof sheet 3 is a rubber system such as vulcanized rubber, an adhesive (for example, a butyl rubber type) can be used. And). Moreover, when the waterproof sheet 3 is a resin type, it can also be joined by heat welding. (Water Storage Method) Hereinafter, the water storage method of the present embodiment will be described with reference to the flowchart of Fig. 6 and the like. (1: Preparation process) When the water storage structure 1 is constructed in the underground of a building, in the ground of a park or a parking lot, the obstacles are removed and safety measures are taken. (2: Excavation process) The floor shape is formed into a rectangular shape and is grounded. (3: Basic process) The bottom surface is a surface of the foundation, or a concrete flat portion is formed by concrete construction. (4: bottom sheet process) In order to prevent damage of the waterproof sheet 3, the protective sheet 4 is first laid on the bottom surface so as not to cause wrinkles, and thereafter the waterproof sheet 3 is applied. Further, in the case where the laying area of the waterproof sheet 3 is large, the waterproof sheets 3 are joined to each other. For example, as shown in FIG. 7, one of the waterproof sheets 3 is attached with a primer, the other waterproof sheet 3 is attached with a connecting tape, the waterproof sheets 3 are joined, and the joined portion is pressed by a hand. Rolling. (5: Filling material assembly step) On the waterproof sheet 3 laid on the bottom surface, a three-pronged corner piece 51 is disposed at a position where the side portion 25 and the vertex portion 26 on the lower side of the filler 2 (the block 22) are disposed. And an L-shaped corner piece 52. Thereafter, a predetermined number of blocks 22 are stacked on the three-corner corner member 51 and the L-corner member 52 which are disposed so as to be shifted from each other in the direction of the bent portion 23 and the groove portion 24 to form the filler 2. After the filler 2 is formed, the remaining three-corner corner piece 51 and the L-shaped corner piece 52 are placed on the side portion 25 and the apex portion 26 of the filler 2 (see Fig. 8). And finally, a spacer is embedded in the uppermost portion of the filler 2. (6: Side sheet process) As shown in Fig. 9, the waterproof sheet 3 laid at the bottom is joined to the three-corner corner piece 51 and the L-corner piece 52 attached to the side portion 25 and the apex portion 26 of the filler 2 It is applied to the side of the filler 2 in such a manner as to wrap it. As a joining method of the three-corner corner piece 51 and the L-shaped corner piece 52 of the waterproof sheet 3, for example, in the case where the waterproof sheet 3 is a resin type, it is preferable to join by heat welding, and the waterproof sheet 3 is rubber. In the case of the system, it is preferred to use an adhesive to bond. Then, the protective sheet 4 is laid so as to wrap the outer side of the waterproof sheet 3 (in addition, the protective sheet 4 is not joined to the waterproof sheet 3). (7: Upper surface sheet process) On the upper surface of the filler 2, the waterproof sheet 3 or the water-permeable sheet (non-woven fabric) is laid and joined to the waterproof sheet 3 which is attached to the side surface of the filler 2. Thereby, it is completed as part of the water storage tank. (8: Backfilling) In order to prevent the movement caused by the earth pressure from the side or the displacement of the waterproof sheet 3 and the protective sheet 4, the soil is placed in a highly balanced manner on the upper surface instead of the heavy stone, and the partial load from one direction does not function. After the four sides are equally backfilled to the outer circumference, as shown in FIG. 10, the upper portion is backfilled to a specific height. Thereby, the above-described water storage structure 1 can be constructed in the underground of a building or in a park, a parking lot, or the like. (Effects) According to the water storage method and the water storage structure 1, the corner piece 5 having the shape of the covering side portion 25 or the like is disposed in the side portion 25 of the filler 2 having irregularities due to the gap, and the waterproof sheet can be used. When the material 3 covers the filler 2, the waterproof sheet 3 is prevented from hooking the side portion 25 of the filler 2 having irregularities, and the filler 2 (block 22) is prevented from deviating. Thereby, the workability of the side portion 25 of the filler material 2 having a square shape can be improved, and the formation of the water storage tank can be made simpler, the result is less likely to be affected by the operator's proficiency, and the cost of labor and the like can be reduced. Further, according to the water storage method and the water storage structure 1, the apex portion 26 (the intersection of the three sides) of the filler 2 can be covered by the simple construction step by the trigeminal corner member 51. Thereby, the workability of the apex portion 26 of the filler material 2 having a square shape can be improved. Further, according to the water storage method and the water storage structure 1, the side portion 25 of the filler 2 can be covered by a simple construction step. Thereby, the workability of the side portion 25 of the filler material 2 having the square shape can be improved. Further, according to the water storage method and the water storage structure 1, when the filler 2 is covered with the waterproof sheet 3, since the corner member 5 is in a flat shape in contact with the waterproof sheet 3, the use of the filler 2 can be improved. The side portion 25 and the apex portion 26 are workable when the waterproof sheet 3 is staggered or bent. Although the present invention has been described in detail with reference to the specific embodiments of the present invention, it is to be understood that various modifications and changes can be made without departing from the spirit and scope of the invention.
