<p>[Problem] To provide an underground structure that has a simple configuration due to taking the support of earth pressure in the horizontal direction into consideration, that can be transported without using pallets, that can easily be transported and installed, and that enables installation costs to be kept to a minimum. [Solution] An underground structure (1) is provided with multiple vertical members 2 (2A to 2D) positioned apart from each other, and connecting members (3 (3A, 3B)) which integrally connect the multiple vertical members. Projections (2b) opposing each other are disposed on the vertical member (2A) positioned on the end of the underground structure in the horizontal direction, and on the vertical member (2B) adjacent to the vertical member (2A), and the projections come into contact with each other. The multiple vertical members are each formed in the shape of a plate, and each plate-shaped vertical member can be equipped with a hole (2c) on the surface on the opposite side of the surface on which the projection is erected, into which a projection with the same shape as said projection can be inserted. The multiple vertical members are preferably formed in the same overall shape. Open holes for rainwater flow through, which penetrate in the horizontal direction, are disposed on each of the multiple vertical members, enabling a structure for a rain water storage and osmosis facility to be configured.</p> |
