Sacrificial anode-mortar composite cathode protection system for offshore steel structure cathode protection and application method of sacrificial anode-mortar composite cathode protection system
The invention discloses a sacrificial anode-mortar composite cathode protection system for offshore steel structure cathode protection and an application method of the sacrificial anode-mortar composite cathode protection system. The system comprises an annular conductive mortar pouring body surrounding the outside of a steel structure and at least two sacrificial anode mortar briquettes arrangedin the annular conductive mortar pouring body, and the mortar ratio of the sacrificial anode mortar briquettes is consistent with that of the annular conductive mortar pouring body. Zinc belt anodes are buried in the sacrificial anode mortar briquettes, and a wire is welded to one end of each zinc belt anode is led out of the sacrificial anode mortar briquettes and is electrically connected with acopper guide wireguided out of the surface of the steel structure. According to the sacrificial anode-mortar composite cathode protection system for offshore steel structure cathode protection and the application method of the sacrificial anode-mortar composite cathode protection system, the mortar conductivity used during repairing and maintaining can be determined according to the needs of thecondition in the field, the mixing amount of lithium bromide is determined according to the application environment to prepare conductive mortar, effective protection on the steel structure is guaranteed, and the engineering cost can be greatly reduced.
本发明公开了一种用于海上钢结构阴极保护的牺牲阳极‑砂浆复合阴极保护系统及其应用方法，该系统包括包围于钢结构之外的环形导电砂浆浇筑体、内置于环形导电砂浆浇筑体内的砂浆比与环形导电砂浆浇筑体一致的至少两块牺牲阳极砂浆试块，牺牲阳极砂浆试块内部埋设有锌带阳极，锌带阳极一端焊接导线引出牺牲阳极砂浆试块外部并与从钢结构表面引出的铜导线电连接。本发明可以根据现场情况的需要来确定维修维护中所使用的砂浆导电率，根据应用环境确定溴化锂的掺量来配制导电砂浆，不仅保证钢结构的有效保护还可以大大降低工程成本。
