PROBLEM TO BE SOLVED: To construct a concrete structure by using a quadrangular panel-shaped relict form, and to perform greening by planting plants in the concrete structure, in the construction of the vertically inclined and horizontally curved concrete structure. SOLUTION: In a permanent form method wherein the quadrangular panel-shaped relict form (2) is used in the construction of the vertically inclined and horizontally curved concrete structure, the permanent form (2) is vertically framed on curved foundation concrete (1). Freshly mixed concrete is placed in the permanent form (2), and after that, a new permanent form (2) is vertically framed on concrete (5), wherein the placed freshly mixed concrete has been solidified, in such a manner as to be displaced backward with respect to the above relict form (2). Freshly mixed concrete is solidified by being placed in the new relict form (2). Subsequently, this process is sequentially repeated so that the concrete structure can be constructed in a staircase pattern up to a predetermined height. COPYRIGHT: (C)2005,JPO&NCIPI
