摘要： A tank wall comprises a concrete body, a plurality of reinforcement elements disposed in the concrete body, and a plurality of attachment elements disposed in the concrete body. The concrete body has a top surface, a bottom surface opposite the top surface in a vertical direction, a flat surface extending in the vertical direction between the top surface and the bottom surface, and a tapered surface disposed opposite the flat surface. The flat surface extends perpendicular to the bottom surface and a portion of the tapered surface extends at an acute angle with respect to the bottom surface. The reinforcement elements include a plurality of reinforcement strands and a plurality of monostrand anchors between which the reinforcement strands are attached. The attachment elements include a plurality of U-shaped bars extending through the top surface of the concrete body.
