There were problems such as processing. Furthermore, the recently developed method of inserting a metal member and driving a wedge has a lot of wear, loss and breakage of the metal member and the wedge. There is a disadvantage in that the distribution cannot be transmitted evenly due to the side pressure from the retaining wall being abdominal.
