An inspection well seat comprises an inner-ring type supporting table which is arranged on an opening portion and used for containing an inspection well lid. The inspection well seat is characterized in that a protection net is fixedly arranged at the position, below the supporting table, of the well wall through expansion bolts, and a danger flag is arranged at the position, below the supporting table, of the well wall through other expansion bolts and a spring; and the danger flag is located between the protection net and the well lid. Due to mounting of the spring, the danger flag can automatically stretch out of an inspection well under the elastic action to be erected upwards. A reflecting marking strip is arranged on the danger flag. By the adoption of the inspection well seat, after the inspection well lid is lost, the danger flag can automatically stretch out of the inspection well instantly to be erected upwards, and pedestrians and vehicles are cautioned to pay attention, so that falling or car accidents are prevented from happening. After the well lid is damaged or lost, the internally-arranged protection net can effectively prevent the pedestrians and wheels from falling off, and the safety performance is improved in a doubled manner. The inspection well seat has the advantages of being simple in structure, easy to mount and good in protection effect.
