Prefabricated well ring and well lid integrated structure of asphalt concrete pavement and construction method thereof

Abstract

The invention discloses a prefabricated well ring and well lid integrated structure of asphalt concrete pavement and a construction method thereof and belong to the field of municipal road engineering. A lengthened screw is pre-embedded into a prefabricated well ring, and elevation of a well lid base can be adjusted by adjusting a nut on the lengthened screw, so that on one hand, an adjusting amplitude of the well lid elevation can be increased, and accuracy and control precision of the well lid elevation are improved, on the other hand, a distance between the prefabricated well ring and the well lid base as well as a concrete pouring thickness are further increased to improve concrete pouring compactness and guarantee finished product strength of concrete on the lower part of the well lid. The method is simple in construction, good in effect, improves construction progress, improves the lower strength of the well lid, guarantees the construction quality, reduces later-stage maintenance times, and reduces road maintenance cost. After road traffic opening, the structure can effectively resist vehicle load, prevents well lid settlement and well periphery pavement damage due to insufficient well-mouth strength, and has better guarantee for travelling comfort and travelling safety.

Description

Technical field[0001]The invention belongs to the field of municipal road engineering, in particular to an integrated structure of an asphalt concrete pavement prefabricated well circle and well cover and a construction method thereof.Background technique[0002]At present, during the construction of urban municipal road engineering, various professional pipelines are simultaneously constructed along the road. Various pipeline inspection well covers are located on the range of asphalt concrete pavement. The traditional construction methods of inspection well covers mainly include mortar brickwork, height adjustment and installation of well covers, and prefabricated well circles. Use pad or mortar to adjust the height and install the manhole cover.[0003]These construction methods are low in cost and simple in construction, 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 circumference of the manhole ...
