It was considered that there was one steel sheet pile (Type III) on the pipeline. Since the road in the construction section is a arterial road with a lot of traffic & it is difficult to regulate traffic, we decided to cut this existing steel sheet pile (Type III) by the milling mall method.
As a result of construction, one steel sheet pile type III was cut.
