EARTH RETAINING METHOD AND EARTH RETAINING UNIT
PROBLEM TO BE SOLVED: To provide a safe earth retaining method that prevents a collapse of an excavation groove with an even greater certainty, in an excavation work in which a prescribed construction work is performed while cutting the excavation groove, in a construction work space adjacent to the excavation groove.SOLUTION: An earth retaining method is used when a prescribed construction work is performed in a construction work space 34 adjacent to an excavation groove 3, while cutting the excavation groove 3 for the construction work from a ground surface 30. An earth retaining unit is installed inside the excavation groove 3 as the cutting work progresses, the earth retaining unit having an earth retaining wall that covers three surfaces of the excavation groove 3, among excavated wall surfaces of the excavation groove except for a construction work surface 10 facing the construction work space 34. The construction work is performed in the construction work space 34 from inside the excavation groove 3, while supporting with the earth retaining unit earth pressure P from three surfaces except the construction work surface 10.SELECTED DRAWING: Figure 5
【課題】掘削溝を開削しつつ、掘削溝に隣接する施工空間に対して所定の施工作業を行う開削工事において、より確実に掘削溝の崩壊を防止し、安全な土留工法を提供する。【解決手段】地表３０から作業用の掘削溝３を開削しつつ、掘削溝３に隣接する施工空間３４に対して所定の施工作業を行う際の土留工法であって、掘削溝３の掘削壁面のうち、施工空間３４に臨む施工面１０を除く三面を覆う土留壁を有する土留ユニットを、開削の進行に伴って掘削溝３内に沈設し、土留ユニットにより施工面１０以外の三面からの土圧Ｐを支えつつ、掘削溝３内から施工空間３４に対して施工作業を行う。【選択図】図５
