As shown in FIG. 7, the guide rod 30 is made of H-shaped steel and has a length substantially equal to that of the width determining member 15, and a lower surface of one end thereof has a side surface of the vertical frame rod 1 or the relay rod 20. A wedge hole 32 for inserting a wedge 33 (see FIG. 10) that presses against the side surface of the vertical frame rod 1 or the relay rod 20 is provided at the other end portion. . And the guide rod
An engaging body 34 having an engaging groove 35 which can slidably engage the male rod of the joint member 41 of the steel pipe A in the vertical direction is provided at the center of one side surface of the steel pipe A.

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 in parallel on both sides of the excavation hole B for erection of the steel pipe A, with the engaging portion 3 as a base end.
The engaging piece 12 is engaged with the mold steel 40 and placed. Then, as shown in FIG. 9, the neck rods 5 at the base ends of the two vertical frame rods 1
The engaging notches 16, 16 of the width determining member 15 are engaged with 5, and the pins 18 are inserted and fixed in the pin holes 7, 7, 17, 17. Relay rods 20, 20 are connected to the two vertical frame rods 1, 1, respectively. The connection between the vertical frame rod 1 and the relay rod 20 is, as shown in FIG.
The vertical plate 8 and the insertion groove 21 are engaged with each other to form wedge holes 9, 9, 2.
A wedge 25 is driven into the holes 2 and 22 and the pin holes 11
This is performed by inserting the pin 26 into the pin hole 24 overlapping the hole.
At the other ends of the connected relay rods 20, 20, the vertical frame rods 1, 1 are further provided in the same manner as described above, and the width determining member 15 is engaged and fixed to the ends thereof in the same manner as described above.

The guide rod 30 is a vertical frame rod 1, 1 or a relay rod facing the guide wall installed as described above.
At a predetermined position on 20, 20, as shown in FIG. 10, the abutment 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. I 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 set at a predetermined position using the engaging groove 35 as a guide. When the steel pipe A has been installed, the wedge 33 is removed, the guide rod 30 is moved to a predetermined position for installing the next steel pipe, and the wedge 33 is driven and fixed. By repeating this operation, the steel pipes A and A are erected while being connected, and the steel pipe column retaining wall is installed. The distance between the opposed vertical frame rods 1 and 1 can be arbitrarily changed by using different lengths of the width determining member 15.

The steel pipe column retaining wall is not limited to a straight plane,
In some cases, the facilities are folded. Therefore, it is necessary to arrange the guide wall in a bent shape in order to cope with it. FIG. 11 to FIG. 13 show examples in which such a bent portion can be used.

In the above-mentioned bending portion, there are used a bending rod 50 formed so as to be freely bent and a telescopic bending rod 51 formed so as to be able to be bent and changed in length. The bent rod 50 is formed by connecting a pair of rods 52, 52 formed of H-shaped steel so as to be rotatable in a plane direction by shaft pins 53 that are upright with each other. Is fixed to the end of one of the vertical frame rods 1 and 1 via a through hole 54 by a bolt and nut (not shown).

The telescopically bent rod 52 is formed by connecting a pair of rods 56, 56 formed of H-shaped steel so as to be freely rotatable in a plane direction by shaft pins 53 which are upright. A sliding groove 57 having an inverted T-shaped cross section is formed at an outer end thereof.
58 is inserted, and an end plate having a through hole 54 at the outer end of the access rod 58
59 is fixed. This telescopic bending rod 52 is also connected to the other vertical frame rod 1, 1 in the same manner as the bending rod 51.

As described above, the bending rod 50 is connected to one of the vertical frame rods 1, 1 and the telescopic bending rod 51 is connected to the other vertical frame rod 1, 1 opposed thereto. -Forming
The substantial length of the telescopic bending rod 51 is adjusted by entering and exiting the sliding groove 57 and the insertion rod 58, and the telescopic bending rod 51 can be installed with a flexible bending angle corresponding thereto.

[0021]

As described above, according to the present invention,
Since the steel members can be easily installed simply by mechanically assembling them on site, the construction period can be shortened.
Also, after the construction of the earth retaining wall, it can be dismantled and carried out, and it can be reused, which leads to a reduction in construction cost. Will also be resolved.
