The regular hexagonal spiral notch is welded in the center of the seesaw. The regular hexagonal spiral bulge, drill body and drill bit are welded in sequence from top to bottom. The drill body is a hollow structure, and the upper part is a water injection port and is punched around it to form a water outlet hole. The spiral triangular steel belt is welded to the drill body from top to bottom or bottom to top circumferentially to form a screw-in drill body. A wiring terminal is welded to the top of the drill body. The present utility model solves the disadvantages of long test time, heavy consumables and multiple tests in traditional test methods, so not only is the volume small, the dead weight is light, it is convenient to carry and use, but also the test efficiency is greatly improved, the accuracy of the test is improved, the test time is reduced and the personnel and material costs of the test are saved.

The drill bit can break the stone due to the impact of the hammer. Finally, the drill body can smoothly penetrate the sandstone soil. Then the resistance of the grounding pole is measured, and if it is higher than 30 ohms, it is necessary to inject water or resistance-reducing liquid into the liquid injection pipe. Water or resistance reducing liquid enters the ground around the drill body through the liquid outlet hole to reduce the resistance value so that the resistance value is less than 30 ohms. Then the wires are installed on the ground wire terminals to continue further construction work.

At the same time, the present utility model is equipped with a crowbar to complete the work construction. The round hole at the end of the crowbar is placed on the crowbar branch by a crowbar and adjustable pivot seat, allowing the drill body to be quickly removed from the ground.

The Advantageous Effects According to the Present Utility Model: The easy-to-operate hollow side hole conduit grounding stake is provided, which can break stones, so that the drill body can easily penetrate the sandstone soil. Water or drag reducing liquid completely infiltrates the ground around the drill body from the liquid outlet hole, so that the resistance value is reduced quickly and effectively.
