Description

Technical Field

[0001] The utility model relates to the technical field of road drainage systems, in particular to a road rainwater well auxiliary device. Background Art

[0002] With the continuous improvement of urban infrastructure construction, urban roads are increasingly using asphalt pavement to beautify roads and improve the comfort of motor vehicle traffic. During the construction of urban roads, drainage pipe facilities need to be planned, designed, constructed and accepted simultaneously. Rainwater discharge outlets are mostly set near the shoulders of the road, and cast iron manhole covers and manhole frames are often used. The periphery of these manhole frames is in direct hard contact with the paved asphalt. After the construction is completed, the asphalt pavement around the manhole frame is very smooth and beautiful. However, after a period of car rolling, the asphalt will creep, and the creep of the asphalt will be hard hindered by the manhole frame. The asphalt around the manhole frame will arch around, and the manhole cover will sink relative to the road surface, thereby destroying the flatness of the road surface, causing inconvenience to vehicle traffic, seriously damaging the comfort of passengers, and even having a serious impact on the safety and life of the vehicle.

[0003] In order to solve the quality problem of the bulge of asphalt around the rainwater well frame causing the sinking of the well frame and the well cover, the road maintenance unit usually cuts off the asphalt pavement around the well frame and repairs it with cement materials for a second time. Although cement can make up for the secondary sinking of the road, the maintenance cycle of cement repair is long and the appearance of the road surface is poor. If asphalt is used for filling, although the appearance can be basically unified, the cost of road maintenance and use is increased, and it may even increase the risk of secondary sinking. For this reason, we provide a road rainwater well auxiliary device that can be installed and used. Utility Model Content
