Construction technology of manhole cover device for inspection well on road

Abstract

The invention discloses a construction process for a manhole cover device on a road. The construction process for the manhole cover device on the road comprises the steps of breaking an asphalt concrete and a part of base layer, blowing off scums on the periphery through high pressure air, spraying water for wetting, leveling for stabilizing a well curb, erecting a form on the inner side of the well curb, mixing a super-early strength black C30 concrete, and pouring the concrete. According to a process technology for solving the problems of sinking and instability of a manhole cover, the sinking problem of the manhole cover is solved by using a technological achievement of rising a manhole through the super-early strength black concrete, a manhole cover installing or a sunken manhole covermaintaining process, and a combined application technology of the technological achievement of rising the manhole through the super-early strength black concrete and a novel composite manhole cover;a back circle problem of the 'technological achievement of rising the manhole through the super-early strength black concrete' is solved; the instability problem of the manhole cover is solved; an anti-falling problem is further solved according to the needs; and through the two process technologies, the aims of small construction surface, timeliness and quickness can be achieved.

Description

technical field [0001] The present invention (invention) belongs to the field of municipal technology, and relates to an installation (method) of inspection well covers on roads. The technology is applied to the installation and construction of inspection well covers on newly built or repaired roads. Background technique [0002] With the increase in the share of family cars in our country, people have also paid great attention to urban road facilities, which immediately highlighted the common problems of urban road facilities. Among them, the subsidence of the manhole cover and the sound of the manhole cover on the road are the most discussed issues. It has not been fully resolved for many years. This problem not only increases the difficulty, workload and maintenance cost of road maintenance, but also is a source of safety risk that causes traffic accidents. At present, most urban roads in my country use lime-stabilized soil, lime-fly ash stabilized soil, lime-fly ash-sta...

Problems solved by technology

[0005] 2. The construction quality problem of subsidence of the road inspection well cover is difficult to solve. The main reason is that the well frame is not firmly embedded in the ordinary C30 concrete. There are two main reasons for this problem. (1) The next step of construction disturbs the ordinary C30 concrete. For example, when the surface layer is rolled, the vibratory roller rolls the manhole cover; (2) the disturbance of ordinary C30 concrete by traffic vehicles; currently, these two disturbances of ordinary C30 concrete are almost impossible to solve

[0006] 3. The problem of manhole covers. At present, most of the wells use ductile iron manhole covers. Manhole cover manufacturers add neoprene rubber pads to prevent the manhole covers from jumping. Neoprene rubber pads are easy to age and need to be replaced regularly. If it is not timely, there will be bouncing sound. After a long time, the height difference between the well frame and the well cover will increase, and the bouncing sound will become more serious.
