手２内に貫入して土砂を継手２内から排除している。Conventionally, as a generally used steel pipe sheet pile, 2A which shows the top view which connected each steel pipe sheet pile 1 with the joint 2 respectively.
There are two-port type shown in the figure, pipe T type shown in FIG. 2B, and pipe type shown in FIG. 2C. In order to make the sheet pile wall connecting these steel pipe sheet piles 1 waterproof, Mortar is injected into the joint 2, but since earth and sand enter into the joint 2 when each steel pipe sheet pile 1 is placed, insert an air pipe or water jet pipe into the joint 2 before injecting mortar. The earth and sand are excluded from the joint 2.
しかしながら、継手２内に侵入した土砂は、かなり密に

ーバフロして排除される。As a means for solving the above problems, the method for removing soil in a steel pipe sheet pile joint of the present invention is a vibro hammer or other vibrating pile chucking plate that is firmly fixed to the upper end of the water jet pipe by welding or other appropriate means. While driving the vibrating pile driver in a state where it is chucked by the chuck of the hammer, the lower end of the water jet pipe that is ejecting the pressure water that has been pumped through a high pressure hose is the lower end in the joint of the steel pipe sheet pile. The water jet pipe, which is driven to the bottom by a vibrating pile driver, is also loosened by the pressure water from the lower end of the water jet pipe, and the overflow from the upper part of the joint together with the pressure water. Then eliminated.
以下図面を参照して本発明の実施例を説明するが第１図

下端が継手２内の下端付近まで貫入される。Therefore, when the earth and sand E invading the joint 2 of the steel pipe sheet pile 1 having the sheet pile wall as shown in FIGS. 2A, 2B and 2C is removed by the above apparatus, as shown in FIG.
Pressure water W is supplied to the water jet pipe 4 through a high-pressure hose 8 and, while ejecting the pressure water W from the lower end, the lower end is inserted into the joint 2 of the steel pipe sheet pile 1 to drive the vibro hammer 5. As a result, the water jet pipe 4 is struck by the vibro hammer 5 and the lower end thereof penetrates to the vicinity of the lower end in the joint 2.
この時、継手２内に侵入している土砂Ｅはウォータジェ
