The invention discloses an anti-floating well lid. The well lid comprises a lid body and a base, wherein the base is arranged in a bottom well mouth; the lid body is a circular structure fitted with the base; the lid body is connected on the base by virtue of an anti-floating structure; the anti-floating structure comprises a pin, a pin head and a pin bottom; the upper part of the pin is vertically and movably connected on the side edge of the lid body; a groove is formed in the lid body; the pin head is clamped in the groove; an opening which is a T-shaped structure is formed in the base; the opening comprises an upper part and a lower part; the pin is vertically arranged in the opening; and the pin bottom is clamped in the lower part of the opening. The anti-floating well lid is simple in structure, convenient in operation, good in anti-floating effect, capable of effectively preventing a well lid floating phenomenon caused by upward impact force to the well lid when lower pressure is extremely great because of rainwater and the like, and capable of realizing opening of the well lid by rotating.
