【発明の詳細な説明】
この発明は、軟弱地盤における山止め切梁掘削
工法に係り、さらにいえば、山止め壁に囲まれた
地盤中に地盤改良壁を設け、地盤の受働抵抗を高
めたソイルストラツトプレローデイング工法に関
する。[Detailed Description of the Invention] The present invention relates to a method for excavating a pile sill in soft ground, and more specifically, a soil improvement wall is provided in the ground surrounded by a pile wall to increase the passive resistance of the ground. Regarding soil strut preloading method.
（背景技術）
構造物の基礎や地下室等を構築するため地盤を
掘削するいわゆる根切り工事は、
掘削部位の四周に山止め壁を設けると共にこ
れを内側から支持する切梁、腹起し等を設置し
た山止め切梁工法。(Background technology) So-called root cutting work, in which the ground is excavated to construct the foundation of a structure or a basement, etc., requires the installation of retaining walls around the excavated area, as well as struts, sills, etc. to support it from the inside. Installed mountain stop beam construction method.
逆打ち躯体等により山崩れを防止しながら所
期の深さまで掘り進むさか打ち工法。 This method uses an inverted concrete structure to prevent landslides while excavating to the desired depth.
等により行なうのが一般的である。This is generally done by, etc.
この場合、掘削によつて起る地盤の不均衡は、
主に山止め壁に作用する土圧、水圧等の主働側側
圧として発生する。 In this case, the ground imbalance caused by excavation is
It mainly occurs as active side pressure such as earth pressure and water pressure that acts on the retaining wall.
ところで、山止め切梁工法において、前記主働
側側圧を支えるのは、第１図に示した腹起し１、
切梁２等である。いま一つは、山止め壁３の根入
れ部の受働抵抗部分の土圧等受働側側圧によるも
のである。 By the way, in the mountain stop beam construction method, what supports the above-mentioned active side pressure is the upright 1 shown in Fig. 1,
It is a strut beam 2nd class. The other reason is due to the passive side pressure such as the earth pressure of the passive resistance part of the embedded part of the retaining wall 3.
従つて、山止めの安定は、上述の釣合いが十分
保たれることによつて実現する。上記力の相互関
係によつて、周辺に起る現象（地盤の沈下、すべ
き等）、及び架構の大小が決つてくる。 Therefore, the stability of the mountain stop is achieved by sufficiently maintaining the above-mentioned balance. The mutual relationship of the above forces determines the phenomena that occur in the surrounding area (ground subsidence, slope, etc.) and the size of the frame.
地盤の安定性が高い場合は、山止めも軽微なも
ので済む。が、安定性が低い場合は、周辺部への
影響も出やすく、山止めもむずかしくなる。特に
後者の場合、根入れ部分の安定性が低いために、
周辺部への影響も出やすく、その対策が重要とな
つてくる。 If the ground is highly stable, only a minor amount of heaping is required. However, if the stability is low, it will easily affect the surrounding areas and it will be difficult to stop the mountain. Especially in the latter case, because the stability of the embedded part is low,
It is also likely to have an impact on surrounding areas, making countermeasures important.
従来、上記の対策として、下記する方法、手段
が採用実施される。 Conventionally, the following methods and means have been adopted and implemented as the above-mentioned countermeasures.

In the method of excavating a retaining beam on soft ground, ground improvement in which the planar shape is continuous in the ground 6 surrounded by the retaining wall 3 in a parallel cross-shaped, comb-shaped, radial shape, etc. A wall 4 is provided, each soil improvement wall 4 and a retaining wall 3 are brought into contact with each other in a state where an internal repulsive force is exerted by an inflatable soil improvement column 5, and then root cutting work is performed. Soil strut preloading method.
