（産業上の利用分野）
本発明は地盤の所定個所を掘削する際に、掘削域外の地
盤の崩壊を防止する土留方法と、その方法に使用する土
留杭に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an earth retaining method for preventing the ground from collapsing outside the excavation area when excavating a predetermined location in the ground, and an earth retaining pile used in the method. be.
（従来の技術）
従来から、例えば、家屋等の建物に隣接した地盤を掘削
する場合、その掘削によって掘削域外の建物側の地盤が
弛緩したり崩壊して建物が傾く虞れがあるので、掘削域
の外周に沿って土留工を施工することが行われている。(Prior art) Conventionally, for example, when excavating the ground adjacent to a building such as a house, there is a risk that the ground on the side of the building outside the excavation area may loosen or collapse, causing the building to tilt. Earth retaining works are being constructed along the perimeter of the area.
このような土留工としては、従来から適宜長さを有する
Ｈ型鋼からなる親杭を掘削域の外周に沿って所定間隔毎
に地盤に埋設するまで打ち込み、しかるのち、掘削域内
の地盤を掘削しながら、その掘削によって露出する親杭
間に土留矢板を掛け渡し、土留壁を形成するという土留
方法を採用している。Conventionally, for such earth retaining works, parent piles made of H-beam steel having an appropriate length are driven into the ground at predetermined intervals along the outer periphery of the excavation area, and then the ground within the excavation area is excavated. However, an earth retaining method was adopted in which earth retaining sheet piles were strung between the parent piles exposed by the excavation to form an earth retaining wall.
（発明が解決しようとする課Ｂ）
しかしながら、このような土留方法によれば、掘削域内
の地盤の掘削が進行するに従って親杭に対する地盤の支
持力が弱くなり、掘削域外側からの地盤の圧力によって
親杭が掘削域内に傾く虞れが生じ、場合によっては親杭
が倒れて掘削域外の地盤が掘削域内に崩壊し、建物に悪
影響を及ぼすという問題点があった。(Problem B to be solved by the invention) However, according to this earth retaining method, as the excavation of the ground within the excavation area progresses, the supporting force of the ground for the parent pile becomes weaker, and the pressure of the ground from outside the excavation area weakens. This poses a problem in that the parent pile may tilt into the excavation area, and in some cases, the parent pile may fall, causing the ground outside the excavation area to collapse into the excavation area, which may have a negative impact on buildings.
このため、掘削域の外周に沿って形成される上記土留壁
の内周面に腹起こしを付設し、掘削空間を利用して対向
する土留壁の腹起こし間に切梁を架設すること番こより
、親杭の傾動を防止することが行われているが、該切梁
はこの掘削域に建物を築造する時に邪魔になり、作業能
率を低下させるという問題点がある。For this reason, it is necessary to attach a raised wall to the inner peripheral surface of the earth retaining wall that is formed along the outer periphery of the excavation area, and to use the excavation space to erect a strut between the raised walls of the opposing earth retaining wall. Although attempts have been made to prevent the parent pile from tilting, there is a problem in that the strut gets in the way when constructing a building in this excavation area, reducing work efficiency.
又、掘削域の外側地盤に掘削域に沿って所望間隔毎にア
ースアンカーを打設し、このアースアンカーを介して前
記腹起こしを支持することも行われているが、このよう
な方法では敷地外にアースアンカーを打設することにな
って他の地下構造物の支障になるばかりでなく、掘削域
と隣接する家屋との間隔が狭い場所においては実施でき
ないものである。Also, earth anchors are installed in the ground outside the excavation area at desired intervals along the excavation area, and the above-mentioned raising is supported via the earth anchors. This method not only obstructs other underground structures by installing the earth anchor outside, but also cannot be carried out in places where the distance between the excavation area and adjacent houses is narrow.
本発明はこのような問題点に鑑みてなされたもので、切
梁やアースアンカーを採用することなく強固な土留めを
可能にし得る土留方法とその方法の実施に使用する土留
杭の提供を目的とするものである。The present invention has been made in view of these problems, and aims to provide an earth retaining method that enables strong earth retaining without employing struts or earth anchors, and an earth retaining pile used to carry out the method. That is.
（課題を解決するための手段）
上記目的を達成するために、本発明の土留方法は、まず
、掘削域の周縁地盤に該掘削域に沿って所定間隔毎に掘
削域の内外方向に長い長孔を計画掘削深さよりも深く穿
設する。(Means for Solving the Problems) In order to achieve the above object, the earth retaining method of the present invention first includes adding long lengths of material to the peripheral ground of an excavation area at predetermined intervals in the direction from the outside to the outside of the excavation area. Drill the hole deeper than the planned excavation depth.
次いで、これらの長孔内に、下端部に掘削域方向に補強
材を突設してなる土留杭を建込んだのち長孔を埋戻する
。Next, earth retaining piles having reinforcing materials protruding from the lower ends in the direction of the excavation area are erected in these long holes, and then the long holes are backfilled.
しかるのち、掘削域内の地盤を掘削しながらその掘削に
よって露出する土留杭間に土留矢板を掛け渡すことを特
徴とするものである。After that, while excavating the ground within the excavation area, the earth retaining sheet piles are laid between the earth retaining piles exposed by the excavation.
この土留方法に使用する上記土留杭は、垂直な杭材の下
端部に水平方向に突出する補強材を一体に設けてなるも
のである。The earth retaining pile used in this earth retaining method is formed by integrally providing a reinforcing member protruding in the horizontal direction at the lower end of a vertical pile material.

つ容易に埋設させられる。(Function) When constructing an earth retaining structure, first a long hole for burying the earth retaining pile is bored along the excavation area, so the reinforcing material protruding from the lower end of the earth retaining pile is inserted in the direction of the long hole. It can be easily and accurately buried in the ground to a predetermined depth while being guided through a 20-long hole.
こうして土留杭を掘削域に沿って所定間隔毎に埋設した

るが、土留杭が掘削域内に露出すると、掘削域内外の土
圧の均衡が保たれなくなって土留杭が掘削域内に向かっ
て傾動させられる方向にる押圧を受ける。After burying the earth retaining piles at predetermined intervals along the excavation area in this way, when the ground within the excavation area is excavated, the earth retaining piles are exposed from the upper end side as the excavation progresses, and earth retaining sheet piles are hung between the exposed earth retaining piles. When the earth retaining piles are exposed inside the excavation area, the balance of earth pressure inside and outside the excavation area is no longer maintained, causing the earth retention piles to tilt toward the inside of the excavation area. Under pressure.
しかしながら、土留杭はその下端部に掘削域方向に向か
って補強材を突設しているので、この補強材によって土
圧を強固に受止し、切梁やアースアンカー等を用いなく
ても傾く虞れがないものである。However, the earth retaining pile has a reinforcing material protruding toward the excavation area at its lower end, so this reinforcing material firmly absorbs the earth pressure and prevents it from tilting without using struts or earth anchors. There is no danger.

である。(Effects of the Invention) As described above, according to the earth retaining method of the present invention, long holes are drilled in the peripheral ground of the excavation area at predetermined intervals in the direction of the inside and outside of the excavation area, deeper than the planned excavation depth. After drilling and erecting earth retaining piles in these long holes with reinforcing materials protruding toward the excavation area at their lower ends, the long holes are backfilled, and then, while excavating the ground within the excavation area, Since the feature is that the earth retaining sheet piles are laid between the earth retaining piles exposed by the excavation, first, long holes for burying the earth retaining piles are drilled along the excavation area, so that the lower ends of the earth retaining piles are protruded. The earth retaining pile can be accurately and easily buried to a predetermined depth in the ground by keeping the reinforced material facing the long hole and guiding it through the 20 long hole. Since the reinforcing material protruding from the lower end of the is buried so as to protrude inside the excavation area, when the retaining wall is formed by spanning the retaining sheet piles between the retaining piles that are exposed as the ground in the excavation area is excavated, This reinforcing material can firmly absorb the earth pressure from outside the excavation area and eliminate tilting of the earth retaining pile.
