Traditionally, methods for extending Metsusenja wire include (a) a person stretching the Metsusenja wire across the ground between two towers and then pulling it up the tower; (d) one end of the Metsusenja wire being pulled up by a cannon or rocket. Methods are known, such as firing an attached cannonball and passing it across two steel towers, and (c) using a helicopter to run a messenger wire between two steel towers. However, among these conventional methods, method (a) requires a great deal of effort, such as the need to remove branches and carefully remove other obstacles that could get caught when the towers are located between the towers. This method is disadvantageous in that it requires a lot of effort, and is almost impossible to implement in reality. Furthermore, the current method uses gunpowder to launch shells or rockets, which is very dangerous, and the current method of using helicopters has the drawback of being too expensive and not economically viable.

In addition, as another method other than these, a projectile connected to the tip of the Metsusenja wire is launched using a projector that uses the elastic energy stored in an elastic restoring member such as a spring to fire the two steel towers. A method is known in which the above-mentioned projectile The flight distance of the projectile is not very large, and therefore, in the case of a steel tower span with a relatively long extension span, there is an inconvenience that the projectile cannot fly over the two steel towers and falls to the ground between the two steel towers. It was something.

この発明はこのような問題を解消するためになされたも

The present invention has been made to solve such problems, and one embodiment of the method will be described with reference to the drawings.

First, as shown in Figure 1, two steel towers 1 and 2 are to be extended.
In between, a point that is approximately equidistant from both steel towers 1 and 2 is defined as an intermediate point M. Then, a firing point is selected near this intermediate point M, and here the elastic energy stored in the elastic restoring member of a mechanism such as a batting machine is transmitted to a bullet-shaped projectile 3A (3B) as shown in FIG. A projector (not shown) to be used and launched is installed.

After that, using the above-mentioned projector, the Metsusenja wire V is
A projectile 8A with one end attached is fired toward one of the steel towers 1, and the three projectiles are made to reach a point on that steel tower 1, for example, a point P1 on the arm, or , and reach the ground position on the opposite side of the middle point M of the steel tower 1.

Next, using the same projector, the mesh sensor wire t
Another projectile 3B with the other end connected is fired toward the other steel tower 2 and made to fly, and this projectile 3B is made to reach a point on that steel tower 2, for example, point P2 on the arm, or It passes over the steel tower 2 and reaches the ground position on the opposite side of the middle point M of the steel tower 2.

次に鉄塔1上の点P1および鉄塔2上の点P。Next, point P1 on steel tower 1 and point P on steel tower 2.

According to the present invention, while eliminating the (a) or current drawbacks found in the conventional methods described above, it is possible to
Messenger wire can be extended to relatively long tower spans. In addition, since the projectile connected to the ends of the metsenja wire is to be launched from a position near the midpoint M between the two steel towers 1.2, the installation of the projector and the projection work can be carried out in one place. This has the effect of increasing the rationality of the work.
