【発明の詳細な説明】 （産業上の利用分野） 本発明は、土留や締切り、あるいは構造物の一部として
用いる鋼矢板の打設方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for driving a steel sheet pile used as a retaining pipe, a deadline, or a part of a structure.
（従来の技術） 従来、鋼矢板を打設するには、第２図に示すように、最
初に打設した鋼矢板Ａに連結して次の鋼矢板Ｂを打設

補修を余儀なくされていた。By the way, according to the above-mentioned conventional method of driving a steel sheet pile, the third method
As shown in the figure, although the steel sheet pile A that was initially placed is vertically placed in the ground 1, it is gradually inclined and placed as C, D ... The phenomenon occurs. This is because the steel sheet pile to be newly placed is engaged with the existing steel sheet pile only on one side, so that a larger driving force is applied to the opposite side where sliding resistance does not act.
Then, the inclination that occurred for each steel sheet pile in the process of placing a large number of sheets was accumulated, and finally it appeared as a large inclination, and it had to be repaired.
（発明が解決しようとする問題点） このため、従来一般には、同じく第３図に示すように、
適宜鋼矢板の打設が進んだ段階で、クサビ矢板２を打設
し、前記した傾斜角の吸収を図るようしていた。(Problems to be Solved by the Invention) Therefore, in general, as shown in FIG.
At the stage where the steel sheet piles have been appropriately cast, the wedge sheet piles 2 are driven to absorb the above-mentioned inclination angle.
しかしながら、クサビ矢板２は、正規形状の鋼矢板を斜

分な時間がかかるばかりか、製作費用も嵩むという問題
があった。However, the wedge sheet pile 2 must be manufactured by dividing the steel sheet pile of a regular shape into half diagonally, and in this case, it is troublesome to prepare a highly accurate jig for cutting and welding. There is a problem that the procedure is required, not only the extra time is required in the process but also the manufacturing cost is increased.
本発明は、上記従来の問題点に鑑みてなされてもので、
その目的とするところは、補修部材を使用することなく
鋼矢板の垂直打設を可能とする方法を提供することにあ
る。Since the present invention has been made in view of the above conventional problems,
An object of the invention is to provide a method that enables vertical driving of a steel sheet pile without using a repair member.
（問題点を解決するための手段） このため、本発明は、始めに一枚置きに鋼矢板を打設
し、しかる後に前記既設の鋼矢板間に新たな鋼矢板を打
設して鋼矢板相互間を連結するように構成したことを要
旨とする。(Means for Solving Problems) Therefore, according to the present invention, steel sheet piles are first placed every other sheet, and then a new steel sheet pile is placed between the existing steel sheet piles. The gist is that they are configured to be connected to each other.

す。(Operation) In the method for driving a steel sheet pile having the above-described configuration, since the steel sheet piles are first driven every other sheet, it is possible to apply a substantially uniform driving force to the upper end of the steel sheet piles in the horizontal direction. Then, the steel sheet pile can be driven almost vertically. In addition, since a new steel sheet pile is driven between these by using the steel sheet pile that is vertically driven as a guide, this new steel sheet pile can also be driven almost vertically, and a series of cast steel sheet piles is The overall uprightness is significantly increased.
（実施例） 以下、本発明の実施例を添付図面にもとづいて説明す
る。(Example) Hereinafter, an example of the present invention is described based on an accompanying drawing.

設し、かゝる新たな鋼矢板の打設を順次進める。FIG. 1 shows a process of driving a steel sheet pile according to the present invention. In the present invention, among the steel sheet piles A, B, ... Which are to be continuously cast first, the steel sheet pile A that is firstly cast.
On the other hand, one sheet of steel sheet pile C is placed, another sheet of steel sheet pile E is placed next, and such every other sheet is placed. At the time of this placement, a guide member (dummy sheet pile) 11 formed by cutting a steel sheet pile to be used into a short length is used as a guide. And, when the above-mentioned series of casting is completed,
This time steel sheet piles A and C are used as guides and steel sheet pile B is placed between them.
Then, the steel sheet piles C and D are used as guides to drive the steel sheet pile D, and such new steel sheet piles are sequentially driven.

, Is restrained on one side by the guide member 11, but the sliding resistance by this is small, and a substantially uniform driving force is applied in the horizontal direction to the upper end of the steel sheet pile, and its vertical driving is applied. Will be possible. In addition, even if there is an inclination during casting,
Since it is not cumulative like continuous casting, the resulting tilt angle is extremely small. Then, since the existing steel sheet pile is used as a guide and a new steel sheet pile that fills the space between them is driven, this new steel sheet pile can also be driven almost vertically.

できることはもちろんである。In the above embodiment, the guide member for guiding the steel sheet piles to be placed every other sheet is made by cutting the steel sheet piles. However, instead of this, other members manufactured separately can be used. Further, when using an independent guide jig or the like which is not interposed between the steel sheet piles to be driven, it goes without saying that this guide member can be omitted.

The vertical driving is possible, and since the new steel sheet pile is driven between the existing steel sheet piles, the vertical driving is also possible. That is,
It is possible to drive a series of steel sheet piles having excellent uprightness without using a special repair member as in the conventional case, and the driving efficiency is significantly improved. Further, even if the steel sheet pile that was initially cast has an inclination, since it is not a cumulative inclination, the inclination is very small, and it is possible to drive a steel sheet pile with excellent uprightness as a whole.
