HORIZONTAL ERECTION DEVICE AND HORIZONTAL ERECTION METHOD FOR BOARD
PROBLEM TO BE SOLVED: To provide a novel horizontal erection device and a horizontal erection method for a board that replaces a filling pipe used in a conventional chemical feeding method and others and may mitigate excavation work.SOLUTION: A horizontal erection device for a board is used for installing a flexible board 5 in an almost horizontal direction from a predetermined depth of a ground, the flexible board being capable of discharging a fluid in the ground to a ground surface and/or discharging an injection material in the ground. A main part of the device includes: a guide member 2 that is penetrated into and installed or drawn out in a vertical direction, from the ground surface side into the ground; delivery means 3 installed in a state supported by the guide member 2, for driving an expansion member 4 in an almost horizontal direction, in a way that allows expansion, into the ground from a part around a tip of the guide member; and connection means (an anchor 7A and a connected body 45 in an example of Fig. 3) that detachably connects a tip side of the board 5 to a tip side of the expansion member, the board being drawn in from the ground surface side along the guide member 2. The board 5 is towed by the expansion member when the expansion member elongates, and is left in the ground when the expansion member contracts.SELECTED DRAWING: Figure 1
【課題】従来の薬液注入工法などで用いられている注入管に代わる新規で掘削作業を軽減可能なボードの水平建込み装置及び水平建込み方法を提供する。【解決手段】地盤内の流体を地表へ排出可能又は／及び注入材を地盤内に吐出可能な可撓性ボード５を地盤中の所定深度から略水平方向に設置する際に用いられる。要部は、地表側から地盤内に向けて縦方向に貫入配置したり引き抜かれるガイド部材２と、ガイド部材２に支持された状態に設けられてガイド部材の先端側周辺より地盤内の略水平方向に向けて伸縮部材４を伸縮可能に駆動する繰出し手段３と、ガイド部材２に沿って地表側より引き込んだボード５の先端側を伸縮部材の先端側に解除可能に連結する連結手段（図３の例だとアンカー７Ａと結合体４５）とを備え、ボード５が伸縮部材の伸長時に該伸縮部材にて牽引され、伸縮部材の縮小時に地盤内に残置される。【選択図】図１
