EXCAVATION AUXILIARY DEVICE, EXCAVATION METHOD AND LONG SIZE OBJECT BURYING METHOD
PROBLEM TO BE SOLVED: To provide an excavation auxiliary device, an excavation method of using this excavation auxiliary device and also a columnar long size object burying method of using this excavation method, capable of efficiently excavating a desired deep hole even in the case of the ground such as ballast.SOLUTION: An excavation auxiliary device 1 comprises a wall-shaped body 2 for defining an excavation work space S inside this wall surface by bending a balt-like rectangular plate in a cylindrical shape so as to form a vertical wall surface on the ground G, with a rectangular surface having two sides in the vertical direction to the ground G as an opening surface 2f and with the two sides as both end parts and a set of a plurality of shutter plates (10a, 10b, etc.) for shielding the whole surface of the opening surface 2 by a combination. The plurality of respective shutter plates (10a, 10b, etc.) are successively stage-stacked on the opening surface 2 from the lower stage side in response to precipitation of the wall-shaped body 2 caused by excavation work in the excavation work space S, and the ground G inside of the excavation work space S is further deeply excavated.SELECTED DRAWING: Figure 1
【課題】砂利等の地盤の場合であっても所望の深孔を効率よく掘削することができる掘削補助装置及びこの掘削補助装置を用いた掘削方法、更にはこの掘削方法を用いた柱状の長尺物の埋込方法を提供する。【解決手段】掘削補助装置１は、地盤Ｇに垂直方向の２辺を有する矩形面を開口面２ｆとし、２辺を両端部とする帯状の矩形平板を地盤Ｇに垂直な壁面をなすように筒状に折り曲げることによって、この壁面の内部に掘削作業空間Ｓを定義する壁状体２と、組み合わせによって、開口面２ｆの全面を遮蔽する、複数枚のシャッター板（１０ａ，１０ｂ，…）のセットとを備える。掘削作業空間Ｓにおける掘削作業に伴う壁状体２の沈降に応じて、複数枚のシャッター板（１０ａ，１０ｂ，…）のそれぞれを、下段側から順次開口面２ｆに積段して、掘削作業空間Ｓの内部の地盤Ｇを更に深くまで掘削する。【選択図】図１
