Well lid

Abstract

The invention relates to a well lid. The well lid comprises a well lid body and a well lid seat; the well lid seat comprises a well lid base and a well lid side seat which is perpendicularly arrangedon the well lid base, a first limiting block is arranged on the inner side surface of the well lid base, and a damping block is arranged between the well lid side seat on the well lid base and the first limiting block; a second limiting block is arranged on the first limiting block, a noise reduction ring matched with the second limiting block in shape is arranged on the second limiting block, andthe damping block and the noise reduction ring are the same in height; the well lid body comprises a first well lid and a second well lid which are consistent in size and further comprises a rotatingshaft arranged on the surface of the second well lid, the rotating shaft penetrates the first well lid, the first well lid can rotate through the rotating shaft, through holes are formed in the firstwell lid and the second well lid, and positions, on the first well lid and the second well lid, of the through holes are consistent. The well lid of the structure has the damping and noise reductionfunctions and meanwhile is high in applicability.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a well cover. Background technique [0002] As an important part of the urban drainage system, the sewer pipe has become an important municipal engineering facility in urban construction. At present, most of the sewer manhole covers are directly installed in the circular or rectangular circle made of iron steel ring or concrete. On the manhole cover. The existing manhole cover will make a knocking sound when pedestrians pass by or vehicles run over it, causing great troubles to both people and vehicles. Moreover, due to the bumping, the manhole cover will vibrate greatly, which will cause the manhole cover to crack after being used for a period of time Phenomenon, affecting the service life of the manhole cover. In addition, once the manhole cover is stolen or washed away by the water in the sewer, a deep well will be formed on the road. In addition, after the manhole...

AI Technical Summary

Problems solved by technology

The existing manhole cover will make a knocking sound when pedestrians pass by or vehicles run over it, causing great troubles to both people and vehicles. Moreover, due to the bumping, the manhole cover will vibrate greatly, which will cause the manhole cover to crack after being used for a period of time Phenomenon, affecting the service life of manhole cover

In addition, once the manhole cover is stolen or washed away by the water in the sewer, a deep well will be formed on the road. In addition, after the manhole cover is lost, no warning information has been added nearby, so that passing pedestrians or vehicles will fall into it inadvertently. Into a deep well, a safety accident occurs, especially at night
