[0044] The embedding and fixing device comprises two groups of upper clamping plates 30 and lower clamping plates 40 which are arranged in parallel, and the lower clamping plate 40 is provided with a fixing end 50 .

[0045] In this embodiment, the clamping end 10 is used to clamp the reference electrode, thereby ensuring that the reference electrode can be protected when it is vertically buried in the concrete medium, preventing the reference electrode from being damaged, extending the service life of the reference electrode, and preventing the reference electrode from failing.

[0046] See also Figures 1 to 6 As shown, the upper clamping plate 30 and the lower clamping plate 40 are connected via a reinforcing plate, and the reinforcing plate is integrated with the upper clamping plate 30 and the lower clamping plate 40 .

[0047] Furthermore, at least one set of slots 507 is formed on the lower clamping plate 40;

[0048] A connection seat 60 is provided on one side of the lower clamping plate 40 away from the upper clamping plate 30 by a fixed connection method (for example, welding, fastening screws, etc.), and a circular hole is opened in the middle of the upper clamping plate, the lower clamping plate and the connection seat, so that the reference electrode can pass through the upper clamping plate, the lower clamping plate and the connection seat from top to bottom in sequence;

[0054] When the fixed end is inserted and buried in the concrete medium, the electrode buried protection device body buried in the concrete medium may become loose due to the small diameter of the pin. To solve the above problem, please refer to Figures 1 to 6As shown, the plug-in connecting rod 501 is provided with a positioning foot 70, and the end of the positioning foot 70 is arranged in a triangle, and the plug-in connecting rod 501 and the positioning foot 70 are detachably connected.

[0062] When the utility model is used, the reference electrode is first placed in the clamping end portion 10, and then the screw of the fastening connector 101 is continuously rotated so that the outer wall of the reference electrode abuts against the inner wall of the clamping end portion 10, and then the fastening nut of the fastening connector 10 is tightened to clamp the reference electrode;

[0063] Then select a suitable location to ensure that the reference electrode is in a permanently wet environment, such as near a pipeline, at least 300 mm away from the pipeline and at a depth of not less than 1 meter;

[0064] Drill holes with a diameter greater than 60mm and a depth greater than 180mm at the selected location and clean the concrete powder or floating dust in the holes;

[0065] Then, the electrode embedding protection device body 10 is placed in the hole, and then the embedding fixture is continuously rotated, at which time, the teeth in the upper clamping plate of the embedding fixture contact with the rack in the clamping end, and the reciprocating linear motion of the rack drives the clamping end to move its position until the desired depth is reached;
