FORMWORK, AND METHOD FOR INSTALLING FORMWORK
PROBLEM TO BE SOLVED: To provide a formwork with which: it is possible to remove a required space for an earth retaining wall by causing the formwork to function as an earth retaining wall; it is also possible to achieve reduction of an excavating amount of earth and to prevent an increase in a construction cost; in addition, it is possible to omit an earth retaining plate used in temporary installation and to reduce time and workloads required for installing and removing the earth retaining plate.SOLUTION: This invention provides a method for installing a formwork 1 in a ground G excavated by excavation fluid W1. The formwork comprises a formwork main body 11, and a guide pipe 12 for guiding an injection rod 21 of a high-pressure injection unit 2 provided along a vertical direction X2 up to the lower end of the formwork main body 11. The method for installing a formwork comprises first excavating the ground G by injection of the excavation fluid W1 below the formwork 1, and inserting the formwork 1 into the excavated part.SELECTED DRAWING: Figure 3
【課題】型枠を土留めとしても機能させることで、土留めに必要なスペースをなくすことができ、掘削土量の低減を図ることができ、施工コストの増大を抑えることができる。そのうえ、仮設で使用される土留め板を省略でき、土留め板の設置や撤去にかかる時間や手間をなくすことができる。【解決手段】型枠本体１１と、型枠本体１１に対して、上下方向Ｘ２に沿って下端まで設けられた高圧噴射ユニット２の噴射ロッド２１を案内するための案内管１２と、を備えた型枠１を掘削用流体Ｗ１によって掘削された地盤Ｇ内に設置する方法であって、型枠１の下方において先行して掘削用流体Ｗ１の噴射により地盤Ｇを掘削するとともに、掘削した部分に型枠１を挿入していく型枠設置方法を提供する。【選択図】図３
