关于次深井石墨阳极地床施工技术
The Construction Engineering of Second-Deep Well Anode Grounding Beds

摘要: 当存在有屏蔽、干扰或者对埋地管网要实施区域性保护时,选用深井阳极地床是一种有效的措施。但由于其施工技术复杂、造价昂贵, 限制了其使用范围。本文介绍一种施工简便、效果好、造价仅比浅埋式石墨阳极地床贵80%的20米井深石墨阳极地床的组装式施工技术。Abstract: Deep well anode grounding beds are often prefered because of their effectiveness if there is shielding, disturances or a case in which regional pretection is considered necessary for buried pipe network. But its application is limited by complex engineering and expensive in construction.Here is Presented a simple, effective favricating way of construction, by which it is only 80% more expensive in cost than shallow buried graphite anode grounding bed to build up a 20m deep similar one.
