Embodiment Construction

[0032] Shown in conjunction with accompanying drawing, the technical scheme of the present invention is further described:

[0033] A method for installing anti-settling manhole covers for new roads, the technological process is as follows:

[0034] (1) Construction process of asphalt sublayer (coarse material)

[0035] Place the temporary manhole cover at the wellhead by preloading and positioning it → spread the asphalt mixture on the lower layer → static pressure → find out the well position and remove the preloading and positioning temporary manhole cover → install the adjusting ring → install the casing → replenish and tamp the asphalt material around the well→ Pull out the casing → install the anti-settling well cover → initial pressure → adjust the elevation → final pressure

[0036] (2) Construction process of asphalt upper layer (fine material)

[0037] Paving of the upper layer of asphalt mixture → static pressure → find out the well location and remove the well co...

Abstract

The invention discloses an installation method of an anti-sedimentation well lid of a newly-built road. The installation method comprises a lower asphalt surface layer construction process and an upper asphalt surface layer construction process; the upper asphalt surface layer construction process is the same as the lower asphalt surface layer construction process; and the lower asphalt surface layer construction process comprises the following steps of placing a pre-pressing positioning temporary well lid at a well mouth, paving an asphalt mixture on a lower surface layer, performing static pressure, finding out a well position and removing the pre-pressing positioning temporary well lid, installing an adjusting ring, installing a pile casing, supplementing and tamping asphalt materials around the well, pulling out the pile casing, installing the anti-sedimentation well lid, performing initial pressing, performing elevation adjustment and performing final pressing. The road construction quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a method for installing an anti-settling manhole cover for newly built roads. Background technique [0002] At present, with the rapid development of urbanization and the continuous improvement of the city's image, some infrastructure can no longer meet the requirements of the city's status and overall image. At present, municipal roads should not only meet the basic functional requirements, but also be beautiful and comfortable to drive. The defects and common quality problems around the inspection manhole cover in the traditional roadway have added scars to our clean city. Due to the design of the traditional inspection manhole cover The defects of many road surface inspection manhole covers sink, shake and noise, bring hidden dangers to traffic, and safety accidents of inspection manhole cover problems also occur from time to time. [0003] The problem w...
