Wellhead position correction method

Abstract

The invention relates to the field of construction of municipal engineering, in particular to a wellhead position correction method. The wellhead position correction method comprises the following steps: measuring the reference width of a new well frame base, namely the distance between a pair of opposite corners of an original rectangular well frame in the width direction of a pavement; measuringthe reference length of a new well frame base, namely the distance between another pair of opposite corners of the original rectangular well frame in the length direction of the pavement; dismountingthe original rectangular well frame and the pavement facing layers at the four sides of the original rectangular well frame, exposing a pavement base layer, and constructing the new well frame base in a way that the length direction and the width direction of the new well frame base are separately parallel to the length direction and the width direction of the pavement; and covering the new wellframe base by adopting a plurality of rectangular frameless well covers. The length direction and the width direction of the new well frame base and the new frameless well covers are separately parallel to that of the pavement; the pavements on the frameless well covers and the pavements on road surfaces at the four sides of the frameless well covers are the same in grain direction, so the appearance is ensured to be beautiful, the pavements are saved, and a blind channel needs not bypass the well covers.

Description

technical field [0001] The invention relates to the field of municipal engineering construction, in particular to a method for correcting the position of a well head. Background technique [0002] There are certain disadvantages in the location of the existing old manhole covers on urban sidewalks: 1) The position is not parallel to the pavement direction: the position of the old manhole covers is not set regularly, and the pavement on the manhole covers is not parallel to the pavement around the manhole covers, resulting in A large number of pavement materials are cut, which wastes pavement materials; the intersection with the blind road forces the blind road to detour, resulting in the lack of function of the blind road; 2) affects the appearance of the pavement: the sidewalk environment of urban roads is the most intuitive reflection of the city. Old manhole covers The clutter setting doesn't match the sidewalk pavement effect. Contents of the invention [0003] The pu...
