非开挖施工大口径管道阴极保护系统
摘要：
非开挖施工大口径管道阴极保护系统，针对非开挖施工大口径顶管管线(1)进行保护；所述非开挖施工大口径管道阴极保护系统具体构成如下：布置在非开挖施工大口径顶管管线(1)的管道外壁的防护涂层、电连接在非开挖施工大口径顶管管线(1)上的牺牲阳极保护装置(3)；所述牺牲阳极保护装置(3)具体通过在管道上安装的阴极保护馈电装置(113)与非开挖施工大口径顶管管线(1)构成电连接的。本发明提出了一种新形式的阴极保护管道施工系统，其技术效果明显，具有可预期的巨大的经济和社会价值。
摘要（英）：

The invention relates to a cathodic protection system for a trenchless construction large diameter pipeline, which carries out protection aiming at a trenchless construction large diameter pipeline (1). The cathodic protection system for a trenchless construction large diameter pipeline concretely comprises a protective coating arranged on the outer wall of the trenchless construction large diameter pipeline (1) and a sacrificial anode protection device (3) electrically connected to the trenchless construction large diameter pipeline (1), wherein the sacrificial anode protection device (3) forms electric connection with the trenchless construction large diameter pipeline (1) concretely through a cathodic protection feeder device (113) arranged on the pipeline. The invention provides a novel cathodic protection pipeline construction system which has obvious technical effect as well as expectable and great economic and social values.
