Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a connecting wall (connecting line) constructed by an intermittent method (spline method) on a proximity line (here, the proximity line means all lines formed between 10 mm and 700 mm from the boundary). Including walls, matching walls, overlapping walls, etc. The same shall apply hereinafter).

[0002]

[Prior art]

 As a conventional technique, there is a structure of a wall piece for a connecting wall which also serves as an excavating work machine of Japanese Utility Model Publication No. 4-218868, which the applicant has acquired the right. This invention is to construct a wall for connecting walls by a spline method intermittently, to install a plate between adjacent walls in parallel, and to fill the concrete between the plates to connect the connecting walls. Is configured to build.

As the joint structure between the wall bodies, Japanese Utility Model Publication No. 4-39865, that is, a triaxial excavating and stirring machine used for constructing various walls such as a connecting wall, a connecting wall, and a superimposing wall, the triaxial Various walls and inner wall steel plates in which a mold steel material is contained in a soil cement column constructed by a drilling and stirring machine, or JP-A-3-76922, that is, a method for constructing a connecting underground wall and a steel for constructing a continuous underground wall Prior art documents such as manufactured panels disclose a device or invention relating to a wall (including a panel) using a special joint.

[0004]

[Problems to be solved by the device]

 In the connecting wall described above, after connecting a steel plate to the H-shaped steel of the wall body, a plate is provided on this steel plate and filled with fresh concrete to form the connecting wall. Therefore, it is excellent in strength and is most suitable as a permanent underground wall.

However, the only problem is that the work process is complicated, the workability is inferior, and in the sense that it is the connecting wall in the original sense, there is some doubt.

[0006] While the joint structure has an advantage that it can be easily mounted, it may have a problem in sealing or connecting water between the connecting walls.

That is, because of the fitting relationship of the similar type, a water-permeable gap is generated between the connecting walls of the connecting wall, and the water sealing property or the connecting property is insufficient.

[0008]

[Means for Solving the Problems]

 In view of this, the present invention secures the water sealing property, the connection property, and the earth pressure resistance as the connection wall, and connects the connection wall through the wall piece for the connection wall that can be connected with the one-touch connection to the constructed wall member for the connection wall. The following configuration was adopted for the purpose of building a building.

[0009]

[Action]

 The operation of the present invention will be described below.

Wall bodies for connecting walls are constructed at appropriate intervals on the near line by the spline method. Then, subsequently, while removing the earth and sand between the constructed wall bodies for the connecting wall from the upper side (ground side) in principle, the connecting rod is attached to the mounting rod provided on the wall body for the adjacent connecting wall. Engage each of the joints on the wall pieces for use. As a result, the wall piece for the connecting wall is continuously provided between the wall bodies for the connecting wall, and the connecting wall is constructed there (of course, it is a part of the connecting wall in the underground direction).

As described above, when the wall piece for the connecting wall is connected to a part of the wall body for the adjacent connecting wall, the earth and sand below the wall piece for the connecting wall are further removed. At the same time as removing, the wall piece for the connecting wall is further pressed.

After that, when the wall piece for the connecting wall reaches the predetermined ground through the above operation and procedure, the construction of the wall piece for the connecting wall and the construction of the connecting wall are completed. .

Ultimately, the connecting wall is constructed on the proximity line by sequentially performing the above-described operations on the wall bodies for the adjacent connecting walls.

Various structures are conceivable as the structure of the wall piece 4 for the connecting wall as shown in FIGS. 3 to 8, and the structure is formed into a chevron shape in consideration of earth pressure resistance (FIG. 4, FIG. 6, FIG. 8 etc.), a simple and flat structure using a flat plate (FIGS. 3 and 5 etc.), or considering the sealing property of one layer, for example, in the corners 122, 122A of the channel steel 2, 2A, A structure (FIGS. 4 and 8) in which the bent pieces 14 and 14A of the wall piece 4 for the connecting wall stop against each other is conceivable. As described above, the structure of the wall piece 4 for the connecting wall is variously adopted depending on the soil quality, the earth retaining position, the underground wall construction site, and the like.

In the figure, 6 indicates a welded portion.
