Therefore, it was developed to install utility poles directly above the gutters and bury the support poles directly below. However, a gutter space is interposed between the utility pole and the base pole, making it impossible to make a strong connection between the utility pole and the base pole, resulting in the problem that the pole is likely to fall over. In addition, the lower end of the utility pole was fixed to a wide platform that protruded from the upper surface of the gutter, and this platform became an obstacle for walking.

される。 The purpose of this proposal is to erect a highly safe utility pole on the top surface of the existing gutter, where there are no walking obstacles and there is no risk of it falling over. A horizontal gutter block 5 with an open upper end is held between the steel plate 4 provided at the upper end, and both steel plates 2 are attached by bolts 7 vertically passing through both side walls 6, 6 of the block 5. , 4 connected to each other with concrete columns with side grooves.

である。 The steel plates 2 and 4 are substantially square and are fixed by welding to the end plates 8 at the lower end of the upper column 1 and the upper end of the base column 3, and are integrally fixed to the upper column 1 or the base column 3 with tension reinforcing bars 9. In the horizontal gutter block 5, both side walls 6 and 6 and the bottom plate 10 are formed with large thickness, five embedded bolts 7 are arranged in parallel on both side walls 6 and 6, and cap nuts 11 formed at the upper end are attached to both side walls. 6, and the lower end spiral portion 12 protrudes downward from the lower surface. Both steel plates 2 and 4 are provided with a cap nut 11 and a spiral portion 12, respectively.
A through hole 13 corresponding to the above is drilled, a tightening bolt 14 is screwed into the cap nut 11 through the through hole 13 of the upper steel plate 2, the spiral portion 12 is inserted through the through hole 13 of the lower steel plate 4, and the nut 15 is inserted. By tightening with the gutter block 5, both steel plates 2 and 4 can be integrally connected. In the figure, 16 indicates the reinforcing bars of the gutter block 5, 17 indicates the upper steel plate of the same block 5,
18 is an existing gutter block connected to both sides of the gutter block 5, and 19 is a lid of the existing gutter block 18.

ものである。 Therefore, a part of the existing gutter block 18 was cut and removed by the length of the horizontal gutter block 5, and the hole 2 was cut from the exposed ground using an auger of a pole construction vehicle.
A hole 20 is excavated into the ground, a pillar 3 is inserted and buried in the same hole 20, and a horizontal gutter block 5 is installed in the removed portion.
and fix it in a position that matches the existing gutter blocks 18, 18 on both sides, and then
The bolts 1 are connected by joints and filled with mortar 21 on the steel plate 2 as shown in FIG.
The head 14' of No. 4 is embedded in the same mortar 21 to form a flat upper surface. The upper pole 1 is used as a utility pole. The lateral force applied to the upper column 1 is distributed from the steel plate 2 at the lower end through the bolt 7 to the steel plate 4 at the upper end of the column 3 to support the column 3.

得て安全性を著しく向上し得る便益がある。 Since this project is constructed as described above, the existing gutter block 18 is cut and removed, the support pillar 3 is buried in the ground in that position, and the horizontal gutter block 5 is placed in the removed part, and the existing gutter blocks 18, 18 on both sides are installed. Since communication is possible through the horizontal gutter block 5, there is no need to construct a detour gutter, and the utility pole can be easily constructed on the center line of the existing gutter, and the upper pole 1 and the base pillar 3 can be strongly connected. Since there is no need to provide a protruding base above the existing gutter blocks 18, 18, there is no obstacle to walking, and the upper column 1 and the base column 3 are strongly connected by the bolts 7, 7 in the side walls 6, 6. There are benefits that can significantly improve safety.
