The invention discloses an anti-falling manhole cover for municipal engineering. The anti-falling manhole cover comprises a base, an inner ring of the base is equidistantly provided with clamping slots, anti-falling sleeves are clamped and connected into the clamping slots, a manhole cover opening is formed in the position, at the upper ends of the clamping slots, on the base, a manhole cover bodyis clamped into the manhole cover opening, water inlets are formed in the manhole cover body, fixed lugs are symmetrically connected to the outer wall of the manhole cover body, and the fixed lugs are connected with the base through bayonet locks; and clamping rings are fixedly connected to the upper ends of the anti-falling sleeves. By means of the anti-falling manhole cover for municipal engineering, the manhole cover body has the effect of protecting pavements, water is conveniently drained away, the double anti-falling function can be achieved when the manhole cover body is damaged, the anti-falling effect is good, and the safety performance is improved; and additionally, an anti-falling bottom plate is provided with an accumulated water outlet, movable connection with a movable rod is achieved to be used for discharging water inside a sewer under extreme weather, and the condition that water pressure inside the sewer is too large, the manhole cover is washed away, and safety hazards are caused is prevented.
