The guide wall of the present invention is formed by combining the above-mentioned members. A pair of the vertical frame rods 1 are arranged side by side with the engaging portions 3 as base ends on both sides of the steel pipe A sandwiching the digging hole B for erection, and are fixed to the ground in advance for frame fixing H.
The engaging piece 12 is engaged with and placed on the mold steel 40. Then, as shown in FIG. 9, the neck rods 5 at the base end portions of the both vertical frame rods 1, 1.
The engaging notches 16 and 16 of the width determining member 15 are engaged with the pin 5, and the pin 18 is inserted and fixed in the pin holes 7, 7, 17 and 17. Relay rods 20, 20 are continuously provided on both of the vertical frame rods 1, 1. The vertical frame rod 1 and the relay rod 20 are connected to each other as shown in FIG.

While driving the wedge 25 into 2 and 22, the pin hole 11 of the horizontal plate 10
Then, the pin 26 is inserted into the pin hole 24 which overlaps with this.
The vertical frame rods 1, 1 are further connected to the other ends of the connected relay rods 20, 20 in the same manner as described above, and the width determining members 15 are engaged and fixed to their ends in the same manner as described above.

The guide rods 30 are the vertical frame rods 1, 1 or the relay rods of the guide walls which are installed as described above and which face each other.
At a predetermined position on the 20 and 20, as shown in FIG. 10, the contact plate 31 is placed in contact with the inner side surface of the vertical frame rod 1 or the relay rod 20, and the wedge 33 is driven into the wedge hole 32 and fixed. To do. Steel pipe A
The male rod 41 of the joint member is engaged with the engaging groove 35 of the guide rod 30 and can be installed at a predetermined position with the engaging groove 35 as a guide. After the construction of the steel pipe A is completed, the wedge 33 is removed, the guide rod 30 is moved to a predetermined position for constructing the next steel pipe, and the wedge 33 is driven and fixed. By repeating this operation, the steel pipes A and A are built while being connected, and the steel pipe column earth retaining wall is installed. The interval between the vertical frame rods 1 and 1 facing each other can be arbitrarily changed by using width determining members 15 having different lengths.

The steel tube column row earth retaining wall is not limited to a plane straight shape,
It may be constructed in a bent shape. Therefore, it is necessary to install the guide wall in a bent shape to correspond to it. 11 to 13 show an example in which it can be used at such a bent portion.

As the bending portion, a bending rod 50 which is freely bendable and a telescopic bending rod 51 which is formed so as to be bendable and variable in length are used. The bending rod 50 is composed of a pair of rods 52, 52 made of H-shaped steel, which are rotatably coupled in a plane direction by upright shaft pins 53, and a through hole 54 is formed at an outer end of each rod 52. An end plate 55 having an end is fixed and is connected to the end of one of the vertical frame rods 1 and 1 through a through hole 54 by a bolt and nut (not shown).

The expansion / contraction bending rod 52 is formed by connecting a pair of rod members 56, 56 made of H-shaped steel so as to be rotatable in the plane direction by upright shaft pins 53. , Sliding grooves 57, 57 having an inverted T-shaped cross-section that open to the outer end are formed, and an inward / outward rod having an inverted T-shaped cross-section that is slidably engaged with the sliding groove 57.
An end plate having a through hole 54 at the outer end of the access rod 58
59 is stuck. This extendable folding rod 52 is also connected to the other vertical frame rods 1, 1 in the same manner as the folding rod 51.

As described above, the bending rod 50 is connected to one of the vertical frame rods 1 and 1, and the telescopic bending rod 51 is connected to the other of the vertical frame rods 1 and 1 facing each other. -If you form a le,
The expansion / contraction bending rod 51 has its substantial length adjusted by the sliding groove 57 and the insertion rod 58 coming in and out, and can be installed at a corresponding bending angle.

[0021]

As described above, according to the present invention,
Since the steel members can be easily installed on site by simply combining them mechanically, the construction period can be shortened.
In addition, after the construction of the retaining wall, it can be dismantled and carried out, and it can be reused, which leads to a reduction in construction costs and, like the conventional concrete guide wall, it cannot be removed after construction and is left unattended. Will also be solved.
