Construction method of integrated structure of prefabricated well circle and manhole cover on asphalt concrete pavement

Abstract

The construction method of the integrated structure of the prefabricated well ring and the manhole cover of the asphalt concrete pavement of the present invention belongs to the field of municipal road engineering. The present invention pre-embeds the extension screw in the prefabricated well ring, and adjusts the elevation of the base of the well cover by adjusting the nut on the extension screw. In one aspect, the adjustment range of the elevation of the manhole cover can be increased, and the accuracy and control precision of the elevation of the manhole cover can be improved. On the other hand, the distance between the prefabricated well ring and the base of the manhole cover and the thickness of concrete pouring are increased, thereby improving the compactness of concrete pouring and ensuring the finished product strength of the concrete at the lower part of the manhole cover. The method has simple construction and good effect, improves the construction progress, increases the strength of the lower part of the manhole cover, ensures the construction quality, reduces the later maintenance times, and reduces the road maintenance cost. After the road is opened to traffic, it can effectively resist the vehicle load, prevent the settlement of the manhole cover and the damage of the road around the well due to the insufficient strength of the wellhead, and has a good guarantee for the driving comfort and driving safety.

Description

technical field [0001] The invention belongs to the field of municipal road engineering, and specifically relates to a construction method of an integrated structure of a prefabricated well ring and a well cover on an asphalt concrete road surface. Background technique [0002] At present, during the construction of urban municipal road projects, various professional pipelines are simultaneously constructed along with the road. The manhole covers of various pipeline inspection wells are located on the asphalt concrete road surface. Pad blocks or mortar heightening and installation of manhole covers and other methods. [0003] These construction methods are low in cost and easy to construct, but the strength of the lower part of the manhole cover is insufficient. After the road is opened to traffic, the manhole cover and the surrounding circle of the manhole cover will be rolled due to the load of the vehicle, which will cause the manhole cover to sink, and the road surface a...

Problems solved by technology

[0005] The purpose of the present invention is to provide a construction method of the integrated structure of the prefabricated manhole ring and manhole cover on the asphalt concrete road surface, so as to solve the problem of insufficient strength of the lower part of the manhole cover in the traditional construction method of the inspection manhole manhole cover, which is prone to sinking of the manhole cover, and construction waste will be generated when the manhole cover is repaired. and technical issues that affect traffic
