To place concrete efficiently without passing concrete under the lower end of a plate-shaped steel material and without moving the plate-shaped steel material lateral pressure at the time of the placing of concrete.
An underground earthquake-resisting wall consists of a plurality of band-shaped plate steel plates 10 arranged in parallel linearly and discontinuously, cages 12 built around each steel plate 10, one or a plurality of spreader bars 14 connecting the front-rear sections of the cages 12 in clearances among the plate steel plates 10, and concrete 16 placed under the state that these steel plates 10, cages 12 and spreader bars 14 are buried integrally. The placing works of concrete 16 are conducted by repeating the operation of inserting a tremie pipe 18 into the clearances among the plate steel plates 10 and concrete is placed from the tremie pipe 18 while the tremie pipe 18 is drawn up with the placing of concrete.
