Description

{Pl}.

The present invention relates to a multi-hole punching apparatus for use in a base station for a transmission tower, and more particularly, to a multi-hole punching apparatus for punching a perforation hole in which a gunpowder is charged during foundation work of the transmission tower.

As the living standard improves, electric power facilities are increasing around living with the increase of electric power usage. In particular, power transmission towers are essential electric power facilities for supplying electric power generated from power plants to consumers.

In particular, the base of the transmission tower is determined by the designer by means of various loads transmitted from the top of the tower to the foundation, such as compressive force, pulling force, horizontal force, horizontal component force, ground condition and topographical condition, The stability, economical efficiency, and construction workability are compared and finally selected.

Among the basic methods of the transmission tower, the basic method which is considered to be suitable for the domestic situation is the reverse type T foundation and the core foundation type in the general layer, the puddle foundation and pile foundation type in the soft ground, and the N value Rock Anchor-based method is adopted for fresh rock layers with a numerical value of 50 or more.

The above-mentioned basic method should commonly excavate the ground.

In addition, the blasting must be performed before excavation. In order to perform blasting, the ground should be pierced by a hydraulic crawler drill or the like, and the blasting is performed after charging the punch.

Such a blasting method is disclosed in Korean Patent No. 559936. The blasting method is to prevent the disintegration of the gravel, so the length of the hole is indicated in consideration of the excavation depth and the blasting force, And carburizing blasting is performed.

Subsequently, by performing the same operation as the first blasting such as surface cleanup and drilling position marking, it is possible to form excavation arcs for installation of structures in a relatively narrow space by repeatedly drilling the long holes again and repeatedly performing the blasting operations after reloading.

However, the above-mentioned conventional patent also has to be borne by the worker during the boring operation, and it is not economical to invest a lot of time in constructing the transmission tower, and when the work is performed by the workforce, I had a problem that I could not.
