Description

Vertical Root Joint Device for Power Pole and Construction Method Thereof The present invention relates to a vertical root connection device for a utility pole and a method of constructing the same. More specifically, the invention relates to a vertical root connection device for a utility pole and a method of constructing the same, which can reduce tilting and collapse accidents of the utility pole by securing tensile stress, improve grounding resistance by lowering grounding resistance, and improve workability by installing the vertical root on the ground in a state where grounding resistance is increased by a drilling method, adjusting the unbalanced tension, and connecting the vertical root and the utility pole using a detachable connection part. Generally, pole erection is a task performed to raise utility poles to the ground, during which a worker manually holds the pole while it is being raised using an auger crane or backhoe to perform precise position adjustments. Horizontal supports, such as rectangular or arched types, are installed at the bottom of the utility pole to prevent it from falling over and to prevent the pole from falling sideways. That is, when installing distribution line supports, one horizontal bar is installed for the concrete pole (CP) at a depth of about 0.5m below the ground surface, and if the tension is high or the ground is weak, the number is increased to secure the necessary tensile strength. However, conventional horizontal foundation construction methods have a problem in that they fail to withstand tension when installed in locations subject to heavy uneven loads, such as angled poles or anchor points, causing the poles to tilt and, in severe cases, lead to collapse accidents where the poles fall over. Furthermore, in cases where the ground is weak, such as embankments, road slopes, or rice paddies, the poles also tilt or collapse accidents occur if sufficient ground resistance tension is not secured. Therefore, there is a need to improve this.
