[Detailed Description of the Invention] The present invention relates to a reference pile installation method for constructing a continuous underground wall, and the reference pile has a vertically continuous hollow portion and is hinged to a side plate with an opening. A reference pile is constructed of a metal plate whose side part can be opened and closed, and this reference pile is inserted into a vertical hole, and the hollow part and the pile side part are filled with concrete poured into the hollow part, and the concrete is filled with concrete. The metal plate is pressed against the wall of the vertical hole using lateral pressure, thereby positioning the reference pile and preventing leakage of concrete, thereby simplifying the installation of the reference pile and making it easier to excavate grooves between multiple reference piles. .

However, according to this, the concrete filled inside often pushes the sheet out of the predetermined area and hardens as it is. This is a disadvantage in that it becomes an obstacle to trench excavation when a continuous trench is formed by excavating a portion adjacent to the reference pile. In addition, if the sheet is torn when excavating an adjacent area, the sheet will intervene in the concrete poured in the adjacent area with a part attached to the standard pile, and the concrete will harden and continue. An underground wall will be constructed. This not only reduces the cross-sectional strength of the concrete, but also causes the sheet to become a water supply, reducing the water-stopping properties of the continuous underground wall. In addition, after lowering the reference pile into the vertical hole for the installation of the reference pile, temporarily filling the space between the wall of the vertical hole and the reference pile with gravel to position the reference pile,
There is a reference pile installation method in which the gravel is removed after the positioning of the reference pile is fixed by hardening of concrete or the like.

However, this method requires the steps of filling and removing gravel, which complicates the entire work, resulting in a disadvantage of maximizing the construction period and increasing costs. The present invention therefore aims to eliminate these drawbacks and its purpose is to prevent concrete from hardening outside the designated area and to facilitate the drilling of grooves and holes in adjacent areas. The purpose of this is to prevent the sheet from interfering with the concrete and ensure the cross-sectional strength and water-stopping properties of the continuous underground wall. The purpose is to bring about smoothness of work, shortening of construction period, and reduction of costs.

When concrete 4 is poured, the concrete becomes hollow part 1
And the pile side part 8 is filled. That is, the concrete poured into the hollow part 1 is filled into the hollow part 1, flows out into the pile side part 8 through the opening □3, and is also filled with the pile side part 8. The concrete ends of the section 1 and the pile side section 8 are maintained at approximately the same level.The concrete 4 filled in the pile side section 8 uses its lateral pressure to spread out the metal plate 5 and bring it into pressure contact with the wall of the vertical hole 7. As a result, the pile side portion 8, which was closed when the reference pile 6 was fully inserted, is expanded.In this way, when the husband end of the concrete 4 rises, the concrete 4
Due to the lateral pressure, the free end of the metal plate 5 is strongly pressed against the wall of the vertical hole T, and the lateral pressure of the concrete 4 is also applied to the side plate 2, so that the reference pile 6 is positioned. There is no need to put gravel on the outside of the partition plate 9 for positioning. At this time, if a sheet 12 is interposed between the metal plates 5 as shown in the figure, even if there is a gap between the metal plate 5 and the crab in the vertical hole 7, leakage of the concrete 4 will be prevented.

In particular, in this invention, by employing a metal plate, it is possible to prevent the metal plate from being pushed out of the predetermined area, so the reliability of the above effect is high. Also, while sheets are used as partitions between the side plates and the walls of the vertical hole, the sheet will not tear during excavation of the adjacent area and interfere with the concrete forming the continuous underground wall. According to the present invention, the reference pile can be positioned by filling the sides of the pile with concrete. Therefore, there is no need to remove it, so it is possible to ensure smooth work, shorten the construction period, and reduce costs.Simplified discussion of drawings Figures 1 to 3 1 shows the first embodiment, and FIG. 1 is a plan cross-sectional view showing the state immediately after the reference pile is erected in the vertical hole and before concrete is poured, and FIG. 2 is a plan cross-sectional view after concrete is poured. , FIG. 3 is a longitudinal sectional view of FIG. 2, FIG. 4 is a plan sectional view of another embodiment after concrete is poured, and FIG. 5 is a longitudinal sectional view of FIG. 4.
