[0006] Preferably, the bottom cover is wrapped with an ABS plastic layer.

[0007] Preferably, a leak-proof net is provided at the bottom of the base, and the leak-proof net is composed of elastic ropes that are crisscrossed in vertical and horizontal directions.

[0008] Preferably, an "L"-shaped protrusion is further provided on the inner side wall of the lower end of the base, and a through hole is further provided on the frame of the anti-leakage net, and the through hole and the protrusion cooperate with each other.

[0009] Preferably, a second groove is provided on the top of the top cover.

[0010] Preferably, a third groove is further provided on the second groove, a rotating shaft is provided inside the third groove, the rotating rod is connected to the rotating shaft, a pull ring is further connected to the upper end of the rotating rod, and the rotating rod is rotated and placed in the second groove.

[0011] Beneficial effects of the utility model:

[0012] 1. In the utility model, the manhole cover is provided with a top cover and a bottom cover separately, and the top cover and the bottom cover cooperate with each other through threads. If the words or patterns on the top cover are seriously worn and need to be replaced, the top cover can be directly replaced without replacing the entire manhole cover;

[0013] Second, by installing a rubber pad between the manhole cover and the base, it can play a buffering role and avoid abnormal noise when pedestrians or vehicles pass through the manhole cover;

[0014] 3. The bottom cover of the manhole cover is inlaid with an ABS plastic layer, because ADS plastic is not only environmentally friendly, but also strong and light, which can not only reduce the weight of the manhole cover itself, but also maintain the strength of the manhole cover;

[0015] 4. The anti-leakage net adopts a detachable installation method. When it is necessary to enter the well to work, the protective net can be directly removed, which is easy to use.
