The invention discloses a long-service-life steel inspection well cover which comprises an inspection well cover body, an inspection well cover support, sacrificial anode blocks, foundation bolts, foundation gaskets and foundation nuts which are all made of steel. The inspection well cover support is fixed in the cement base through the foundation bolts, the foundation gaskets and the foundation nuts, the inspection well cover is arranged on the inspection well cover support in a covering mode, drainage holes and installation opening holes are formed in the inspection well cover, an installation column is integrally arranged at the bottom of the inspection well cover, external threads are arranged on the outer surface of the installation column, and internal threaded holes are formed in the inner side of the sacrificial anode block. The sacrificial anode block is in threaded connection with the mounting column. After the inspection well cover is installed, if the atmospheric environment corrodes the inspection well cover and the inspection well cover support, the sacrificial anode block is corroded preferentially, and the inspection well cover and the inspection well cover support are prevented from being corroded, so that the risk that the local or overall wall thickness of the inspection well cover is corroded and thinned can be reduced, and the inspection well cover can keep enough mechanical strength for a long time.
本发明公开了一种长寿命钢铁类窨井盖，包括窨井盖、窨井盖支座、牺牲阳极块、地脚螺栓、地脚垫片和地脚螺母，窨井盖、窨井盖支座、地脚螺栓、地脚垫片和地脚螺母均由钢铁制成，窨井盖支座通过地脚螺栓、地脚垫片和地脚螺母固定在水泥基座中，窨井盖盖设在窨井盖支座上，窨井盖上设置有排水孔和安装开启孔，窨井盖的底部一体化设置有安装柱，安装柱的外表面设有外螺纹，牺牲阳极块的内侧设有内螺纹孔，牺牲阳极块与安装柱螺纹连接。本发明窨井盖安装后，若大气环境对窨井盖和窨井盖支座产生腐蚀作用时，牺牲阳极块优先被腐蚀，而窨井盖和窨井盖支座免受被腐蚀，可减少窨井盖局部或全面壁厚腐蚀减薄的风险，使窨井盖长久保持足够的机械强度。
