富水高电阻率区小阻值接地网设计施工研究

Design and Construction Research of Small Resistance Grounding Network in Water-rich and High Resistivity Area

在富水高土壤电阻率区施工接地网,需克服诸多因素的影响。从使用常规材料为前提,通过选择物理高效降阻剂和采取反支模浇筑降阻剂、薄壁铁皮护筒预浇筑降阻剂等措施,避免了高土壤电阻率和流砂等对接地网施工影响。并结合理论计算和PDCA循环原理来主动控制施工结果,为接地网施工提供可靠的经验。

Many difficulties should be overcome when the grounding grid is deployed in high moisture soil. The normal material and methods should be used, including the powerful grounding resistance reduction agent, the anti-shuttering pouring agent, pouring the agent in low thickness iron tube, etc. The construction results should be controlled through theoretical calculation and PDCA circulation theory, and the reliable working experience would be accumulated for grounding grid.
