2. Description of the Related Art Various construction methods are known as construction methods for earth retaining walls. Particularly in large-scale construction, an underground continuous wall construction method is often used in view of the environment, strength and structure. In this method, the ground is excavated using a stable liquid such as muddy water, and after completion of the excavation, a reinforcing cage assembled in advance in accordance with the length, width, and width dimensions of the excavation groove is built into the excavation groove, and then concrete is poured. Then, the underground wall is constructed by replacing with the stabilizing solution. Then, by repeating the above-mentioned operation, a preceding underground wall is constructed at a predetermined interval, and then a similar operation is performed between the preceding walls to construct a continuous wall under the ground. .

[0003] Reinforced baskets are used for the above concrete underground continuous wall. The reinforcing bar cage is formed by assembling reinforcing bars vertically and horizontally in a basket shape. Reinforced baskets exhibit strength when integrated with concrete, but are easily deformed when erected and built, so that this deformation does not occur.
There is also a reinforced cage partially reinforced with a reinforcing frame.

However, underground structures have been increasing in size and depth in recent years. In order to adopt a steel cage for a concrete underground wall of this type, as described above, The technical problem described in (1) occurs.

For example, when a large-scale underground space is constructed at a large depth such as an underground power plant, an underground energy storage facility, and an underground waste disposal site, the excavation depth and the construction depth of the underground wall are several tens of meters underground. It also extends to. Under such conditions, the horizontal force due to earth pressure, water pressure, etc. exerted on the wall surface is extremely large, and in order to counter this, the design wall thickness is three times that of a normal underground wall.

ものとなる。
Accordingly, with the increase in the wall thickness, the construction period due to the increase in the amount of excavated soil increases, the size of heavy construction equipment increases, and the amount of disposal of industrial waste increases. Due to the increase in thickness, the reinforcing bar cage also becomes large, and it is difficult to prevent deformation with a conventional reinforcing structure using a reinforcing frame.

【0007】また、地中壁体の強度を高めるためには、

場合も生ずる懸念もあった。
In order to increase the strength of the underground wall,
Since it is necessary to increase the diameter of the reinforcing bars or to arrange the reinforcing bars densely, there is a concern that cast concrete may not be able to completely fill the gaps between the reinforcing bars.

[0008] As a conventional structure which overcomes such weak points of the reinforcing rod cage and replaces it, for example, Japanese Patent Laid-Open No. 6-1930
No. 49 proposes a steel-walled reinforced concrete underground continuous wall. The technology disclosed in this publication is a steel rebar structure in which front and rear flanges of an H-shaped steel erected in the vertical direction are integrally joined by a plurality of horizontal connecting members, and reinforcing bars are arranged vertically and horizontally on the outer surface side of the horizontal connecting members. Is integrated with concrete to form an underground continuous wall.

Therefore, in this structure, a horizontal strength corresponding to the strength of the steel frame can be obtained, so that the wall thickness can be made smaller than that of a conventional reinforced concrete underground continuous wall.
However, in this structure, there is no problem as long as the width of the excavated groove is the width of the steel frame, that is, the H-shaped steel, if the width matches the length between the two flanges.

On the other hand, if the wall thickness is designed to be large in order to conform to the large depth as described above, there are many cases where it is not possible to use a standard-sized steel material currently on the market. For this reason, if a steel material outside the specified dimensions is required, it is necessary to specify a shape and dimensions suitable for the groove width (wall thickness) and special order to the steel material manufacturer, so the cost of the steel material becomes extremely expensive, There was a problem that the cost of construction cost would rise.
