[0003] Manhole cover refers to the general term for the cover plate and its fixing accessories installed on the manhole with sealing performance. Manhole covers can be divided into protruding type and embedded type according to whether they are higher than the opening surface after installation. Bolt wrenches are required when disassembling and installing manhole covers;
