In the civil engineering work at Kiba Station on the Tozai Line, a steel diaphragm wall using the main unit will be constructed from the road and a temporary earth retaining wall will also be used. However, in order to avoid buried pipelines that are difficult to relocate, part of the plan is to construct a primary retaining wall and use steel diaphragm wall under the road. In this paper, we report the results of steel diaphragm wall construction constructed from the road.
