管桩综合接地体综合电气阴极保护技术探讨

Discussion on Pipe Comprehensive Grounding of Integrated Electrical Cathodic Protection Technology

管桩常用于中高层建筑对其抗竖向及水平方向的荷载都要求较高,但管桩采用焊接及其接头的防腐问题是重要的安全问题,一直没找到理论与实际都行得通的办法,经过系统研究认为采用阴极保护是最有效的办法。又由于管桩在建筑中经常用作接地体,是使用中性接地电流进行外加电源保护电法保护技术之一的极好应用,因此将这些综合在一起,有很多需解决的问题。通过对这些问题的研究,不但从原理上解决了管桩本身心腐技术,而且其也进一步为雷电应用技术拓宽了视野。

Pipe used in medium and high rising building,which have higher requirements to vertical and horizontal loads,but the pipe welding and corrosion of joints are important security issues,no feasible way on theory and practice,through systematic research,the use of cathodic protection is the most effective way.Because pipe is used as touchdown body in the construction,which is excellent application of additional electrical power protection technology using neutral grounding current,so these are integrated together and there are many problems to be solved.Through these studies,not only solve the heart corrosion problems of pipe itself,but also further broaden the horizon for lighting application technology.
