Although the resistance-reducing agent grounding module has special effects on grounding resistance, it should be supplemented with effective measures and correct methods. Construction quality is the key to reducing resistance.
1. Excavate the horizontal groove according to the design requirements. The width of the groove is narrow and the groove bottom is flat. As shown in the upper right figure, the length of the trench is designed according to the design requirements.
2. Straighten the correct round bar or flat steel into the middle of the groove and raise it.
3. Pour the grounding module drag reducer into the mixer or container and stir it to a slightly thicker paste.
4. Placing the paste-resisting agent grounding module evenly around the grounded round steel or flat steel is the key to obtaining an excellent resistance reducing effect. (If you are in a mountainous area, dry powder can be directly wrapped around the grounding body).
5. When the resistance-reducing agent has not yet completely solidified and hardened, it must be covered with high-quality fine clay on it and backfilled and compacted.
6. According to the design requirements of the vertical grounding body, the cylinder-shaped hole is drilled first, and then the steel bar or the angle steel of the grounding body is placed in the center of the hole, and then the resistance-reducing agent is poured into the round hole.
The economic usage of the grounding module should be determined according to different soil quality. The thickness of the laying on the grounding body should be between 8-25cm. For the convenience of calculation, the recommended dosage is as follows:
Because grounding resistance is affected by many factors during construction, only calculation reference is provided:
The new grounding module grounding resistance value Rx = Rg (conventional) × 0.15 ~ 0.60 (resistance reduction coefficient) When the Ï value is large, take a small value of the resistance reducing coefficient, when the Ï value is small, take a large value of the resistance reducing coefficient. Or take it out of experience.
1. Add water to the grounding module/water 2.3/1 at the site. The two can be quickly stirred for about 1-2 minutes in a big mouth container (the container should be easy to move), stir evenly, the bottom of the container can not see dry powder, but it should not be too thin, the whole into a paste, immediately pour Has been placed in the pit of the grounding body (can not be cured and then put), after the first cover with fine soil, not to be tampered, after about five days, fine soil sink, and then fill with fine soil and compact (but not necessary Excessive effort).
The grounding module is extremely bad for soil (such as all-stone soil) or an extremely narrow construction site where it cannot reach the grounding body. If necessary, it may also consider that deep holes are also drilled in the measurement auxiliary pole and the grounding module is filled with a resistance reducing agent.
