まずリング１に鋼板２をセツトする。このとき
外側鋼板２−１は正規の位置、内側鋼板２−２は
外側鋼板２−１に仮付けの状態である（）。 First, the steel plate 2 is set on the ring 1. At this time, the outer steel plate 2-1 is in the normal position, and the inner steel plate 2-2 is temporarily attached to the outer steel plate 2-1 ().
この状態で地切り・吊り上げを行い（）、開
口部ａにリング１を仮合せする（）。 In this state, ground cutting and lifting are performed (), and the ring 1 is temporarily fitted to the opening a ().

In this invention, all the reinforcement is done with two steel plates, so the reinforcement work is greatly reduced, and the inner steel plate is temporarily attached to a ring, and the inner and outer steel plates are suspended in an overlapping manner, and the temporary support beam is used to hold the reinforcement at the opening position. Since the inner steel plate is attached to the correct position after installation, positioning is accurate and workability is good. As a result, construction is simplified and construction efficiency is improved overall.
