摘要

The purpose of this study is to construct a large wall with high height.A first panel (1) having a square cylindrical connection (12) and a square shaped concrete plate (14) receiving one side of the quadrangle from one side in the axial direction of the connection to the connection in the axial direction At least a portion of 0 is disposed in a groove 34 (34) formed in the ground to the upper side, and then a bonding agent (42) having a coagulant is placed in the connection body and the lower end of a second panel (10a) having a quadrangular concrete plate (14) is provided The first and second panels may be inserted into the connection, thereby connecting the first and second panels, and then placing the first and second panels in the groove.
