The invention discloses a novel well lid. The novel well lid comprises a well seat, an upper cover and a damping plate, wherein the well seat covers a well mouth, the upper cover is arranged on the well seat in a covering mode, and the damping plate is arranged between the well seat and the upper cover; a surrounding edge is vertically arranged on the upper surface of the well seat, and the surrounding edge and the well seat are integrally formed; at least two mounting parts are arranged on the bottom surface of the upper cover in the radial direction, wherein two ends of the mounting parts extend outwards to form connecting parts, connecting grooves corresponding to the connecting parts in a one-to-one mode are formed in the surrounding edge, and the connecting parts are clamped in the connecting grooves; the damping plate is of an annular structure, an annular groove used for installing the damping plate is formed in the surface of the surrounding edge, and the damping plate is clamped in the annular groove; two ends of the damping plate are connected with the well seat and the upper cover; and the middle part of the surrounding edge is also provided with an anti-falling net forsealing the well mouth, and the outer edge of the anti-falling net is hung on the inner side wall of the surrounding edge. The novel well lid has the advantages of being reasonable in structure and capable of improving the damping and silencing effects of the well lid.
