Claims

[Scope of utility model registration request]

In an earth retaining wall structure in which a concrete body is used as a wall structure, a reinforcing material in an embankment that maintains the earth pressure acting on the concrete body is connected to the concrete body via a connecting body, and the connecting body includes:
An earth retaining wall structure comprising mechanisms for absorbing rotational displacement and vertical displacement of the concrete body and the reinforcing material relative to each other.
