Manhole cover construction method and auxiliary installation device for pavement inspection well

Abstract

The invention discloses a construction method of a well lid of a road surface inspection well. The construction method overcomes the defects that in the prior art, time for installation work of a well lid base is long, and the consistency of construction quality cannot be guaranteed. The construction method of the well lid of the road surface inspection well comprises the following steps that A, a concrete well ring and a well lid base are integrally prefabricated; B, a well ring foundation pit is dug; C, a well mouth supporting inner formwork is mounted in the well mouth of the inspection well; D, the space between the well mouth supporting inner formwork and the well ring foundation pit is filled with concrete; E, the concrete well ring and the well lid base are hoisted integrally; F, the well ring foundation pit and the prefabricated concrete well ring are filled with concrete, and the concrete is compacted; G, the well mouth supporting inner formwork and a hoisting and leveling device are taken out; and H, an asphalt concrete pavement layer between the well ring and the road surface is laid. The invention further provides an auxiliary installation device. The auxiliary installation device comprises the well mouth supporting inner formwork and the hoisting and leveling device. According to the construction method of the well lid of the road surface inspection well and the auxiliary installation device, construction is simple, work time is short, the dimensional precision of well lid installation is high, and the construction method and the auxiliary installation device are suitable for well lid installation.

Description

technical field [0001] The invention relates to the construction of a municipal inspection well, in particular to a construction method and an auxiliary installation device for a well cover of a road inspection well. Background technique [0002] Over the years, the installation of manhole covers for inspection wells of various pipelines has been a weak link in municipal road construction. The construction quality of manhole covers for municipal roads directly affects the smoothness of the road surface, driving comfort, safety, aesthetics and road life. In the traditional construction technology, the manhole cover seat will directly transmit the pressure from above to the end face of the wellhead of the inspection well. With the increasing driving of heavy vehicles, it is easy to cause the manhole cover to crack, sink and damage Pavement structure reduces the service life of the road. At the same time, the traditional construction technology mostly determines the elevation ...
