Concrete block for side slope stabilization, has springs arranged in installation side, where one spring, which is away from longitudinal axis and lies in area where concrete length decreases, has low spring depth than equal depth springs

摘要

The block has an installation side and grooves provided in a center area of the installation side. Springs (7a-7d) have different spring depths, where concrete length gradually decreases from longitudinal axis up to an elevation side. The springs are arranged in the installation side and the spring (7d), which is away from the axis and lying in an area in which the length decreases, has a low spring depth than the equal depth springs.
