EARTH-RETAINING TIMBERING
PROBLEM TO BE SOLVED: To provide earth-retaining timbering the stability of which can be secured while drilling work is improved in efficiency.SOLUTION: Earth-retaining timbering 1 comprises: a cut beam 20 provided between a pair of opposed earth-retaining walls 10; a cut beam suspension girder 30 provided above the pair of earth-retaining walls 10 and over both the pair of earth-retaining walls 10; and a suspension cradle 40 suspended and supported from the cut beam suspension girder 30 to support the cut beam 20. It is not necessary to support the cut beam 20 with a shelf pile and a wide excavated space is formed right below the cut beam 20. Further, even if a large perpendicular load is placed on the cut suspension girder 30 owing to shakes of an earthquake, the earth-retaining timbering 1 is stable because of the cut beam suspension girder 30 and the ground on the back of the earth-retaining walls 10.SELECTED DRAWING: Figure 2
【課題】掘削作業の効率を向上させつつ、支保工の安定性を確保できる、山留め支保工を提供すること。【解決手段】山留め支保工１は、対向する一対の山留壁１０の間に設けられた切梁２０と、一対の山留壁１０の上方でかつ一対の山留壁１０の両方に跨がって設けられた切梁吊桁３０と、切梁吊桁３０から吊り下げ支持されて前記切梁２０を支持する吊架台４０と、を備える。切梁２０を棚杭で支持する必要がなく、切梁２０の直下に広い掘削空間ができる。また、地震時の揺れによって切梁吊桁３０に大きな鉛直荷重がかかっても、切梁吊桁３０および山留壁１０の背面の地盤によって山留め支保工１は安定している。【選択図】図２
