EARTH RETAINING METHOD FOR CEILING PART OF WIDENED PART, AND WIDENING METHOD FOR UNDERGROUND PART
PROBLEM TO BE SOLVED: To provide an earth retaining method for a ceiling part of a widened part, and a widening method for an underground part, which contribute to safety.SOLUTION: A support beam 30 is provided within a soil layer in an upper part of a location scheduled to be widened, midway through excavation of an underground part. A plurality of earth retaining tools 80 are pushed in while being sequentially added in such a manner as to be guided by the support beam 30, and a ceiling part of a widened part C is earth-retained. The location scheduled to be widened directly below a location earth-retained by the earth retaining tool 80 is excavated, and the widened part C is constructed midway through the excavation of the underground part.SELECTED DRAWING: Figure 8
【課題】安全性の向上に寄与する、拡幅部の天井部分の土留方法および地下部分の拡幅方法を提供する。【解決手段】地下部分の掘削途中にある拡幅予定箇所の上部の土層内に支持梁３０を設け、前記支持梁３０に案内されるように、複数の土留具８０を順次継ぎ足しながら押し込んで、拡幅部Ｃの天井部分を土留する。この土留具８０によって土留された箇所の直下の拡幅予定箇所を掘削して、地下部分の掘削途中に拡幅部Ｃを構築する。【選択図】図８
