【発明の詳細な説明】 産業上の利用分野 この発明は矢板の建込み工法に関する。[Detailed description of the invention] Industrial applications This invention relates to a construction method for sheet piles.
発明が解決しようとする問題点

騒音で矢板を圧入する工法がある。ところがこの工法は
周囲の地盤を弛めるが、土砂を系外に搬出できないので
、矢板建込みの能率が必ずしも高くはなかった。また、
周囲の地盤に多量の水が圧入されて地盤沈下をもたらす
等の欠点があった。Problems to be Solved by the Invention There is a construction method in which jet water or jet water mixed with air is injected from the tip of the sheet pile, loosening the ground around the sheet pile, and press-fitting the sheet pile without vibration or noise. However, although this construction method loosens the surrounding ground, it does not allow the earth and sand to be carried out of the system, so the efficiency of building sheet piles was not necessarily high. Also,
There were drawbacks such as large amounts of water being forced into the surrounding ground, causing ground subsidence.
この発明は上記問題点に着目しなされたものである。そ
の目的は矢板建込みの能率が高く、周囲地盤への影響が
少ない矢板の建込み工法を提案するにある。This invention has been made in view of the above-mentioned problems. The purpose is to propose a method of erecting sheet piles that is highly efficient and has less impact on the surrounding ground.
問題点を解決するための手段

盤上に回収することを特徴とする。Means to Solve the Problem This method of erecting sheet piles is a method of erecting sheet piles by injecting jet water from the tip of the sheet piles to loosen the surrounding ground. Suction holes opening at the top and bottom ends of the sheet piles are provided. The present invention is characterized in that the water that remains after being injected into the ground is collected on the ground together with earth and sand via a suction hole path.

る。Figure 1 shows the concrete sheet pile 1 used in this construction method.
Both edges in the width direction are bent into a U-shaped cross section to form rib portions 2, and suction holes 3 opening at the upper and lower ends are perforated in each edge.

、孔路３の上端開口部には回収管６が連結しである。In order to erect this sheet pile in the ground, as shown in Fig. 2, an opening is made at the lower end of the sheet pile 1 at the center in the width direction on both the front and back sides of the sheet pile 1, and vertically long jetting pipes 4, 4 for jetting water are opened. is installed, and jet water mixed with shet water or air is injected into the ground 5 via this pipe 4. The jet water loosens the ground 5 and at the same time applies downward stress to the sheet pile, causing the sheet pile 1 to loosen.
into the ground 5. In this press-in process, the jet water that is surplus in the ground is collected on the ground 5 through the suction hole path 3 together with the loosened earth and sand of the ground. In the figure, a recovery pipe 6 is connected to the upper end opening of the hole passage 3.
作用および考案の効果
この発明は以上の構成からなる。この建工み工法では、
地盤内に滞留する余分の水を回収するのて地山を過大に
乱すことがなく、地盤沈下が防止できる。また、水の回
収と同時に弛んだ地盤の土砂を搬出するので矢板の圧入
が容易となり建込みの能率が向上する。Operation and Effects of the Invention The present invention consists of the above-mentioned configuration. In this construction method,
By collecting excess water that remains in the ground, the ground is not disturbed excessively, and ground subsidence can be prevented. In addition, since loosened earth and sand from the ground are removed at the same time as water is recovered, it becomes easier to press in sheet piles, improving construction efficiency.
以上の通り、この工法によれば周囲地盤への影響を極小
に抑えて、能率よく矢板の建込みができる。As mentioned above, this construction method allows efficient erection of sheet piles with minimal impact on the surrounding ground.
