Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Embodiment 1: present embodiment is applicable to that electronic mode drives earth electrode, as depicted in figs. 1 and 2, a kind of earth electrode, comprise the body of rod 8, lay respectively at the electronic joint 1 and the drill bit 5 at the body of rod 8 two ends, the liquid filling hole 2 that the described body of rod 8 and electronic joint 1 inside have hollow, the described body of rod 8 surfaces have a plurality of apertures 4 that connect with liquid filling hole 2, and the quantity of aperture 4 can be provided with a plurality of as required.

Electronic joint 1 can be connected with electric hammer, and the shape that is complementary with electric hammer can be arranged in the location the when shape of electronic joint 1 can realize rotating with electric hammer, also can be provided with several can with the groove or the tongue of electric hammer location.According to the electric hammer that adopts, present embodiment is that the mode that has four electronic detents 11 on electronic joint 1 vertically realizes locating.

When using present embodiment, the mode of employing electric power drives earth electrode and buries, and adds liquid resistance reducing agent at the earth electrode filling opening, and liquid resistance reducing agent is penetrated in the soil of earth electrode periphery by the aperture on body of rod surface again, the whole erection process need not to excavate soil, has realized the Fast Installation of earth electrode.

Embodiment 2: the flexibility when using earth electrode in order to increase has increased the mode of manual installation on the basis of embodiment 1.As shown in Figure 3, between the electronic joint 1 and the body of rod 8, be provided with a cylinder ring 3 that protrudes, on described cylinder ring 3, have manual positioning groove 31 vertically.
