Draining and grounding structure of high-strength and large-bending-moment circular concrete pole
A draining and grounding structure of a high-strength and large-bending-moment circular concrete pole comprises prestress main reinforcements, non-prestress main reinforcements, spiral reinforcements, an internal steel hoop and a concrete layer. A grounding conductor is fixed onto the lateral side of the pole. The grounding conductor extends into the concrete layer of the pole from the lateral side of the pole and is welded and connected with the prestress main reinforcements. A threaded hole is formed inside the grounding conductor, and a grounding bolt is connected into the threaded hole in a threaded manner. A draining pipe is further fixed onto the lateral side of the pole. The draining pipe extends into the concrete layer from the lateral side of the pole and is communicated with a hollow layer inside the pole. The included angle between the draining pipe and the horizontal direction is alpha. One end, inside the pole, of the draining pipe forms chamfer gradient towards the interior of the pipe. The draining and grounding structure has the advantages that the pole can be protected effectively and prevented from being damaged by thunder and lightning; rainwater can be drained effectively and prevented from accumulating in the pole; meanwhile, the draining and grounding structure is simple in structure, high in practicality, capable of prolonging the service life of the pole and guaranteeing the safe and stable operation of the pole.
