Abstract
The invention provides a wellbore installing method. The method comprises the following steps that prefabricating is conducted, specifically, a wellbore with the first preset height is prefabricated,and a well lid is prefabricated at the end of the wellbore; bricklaying is conducted, specifically, a well chamber and a wellhead having a second preset height are subjected to bricklaying, and the wellhead is covered and marked, wherein the wellhead is arranged at the top of the well chamber and communicates with the interior of the well chamber, and the sum of the first preset height and the second preset height is equal to the distance between the top of the well chamber and the road surface; installing is conducted, specifically, the road surface is paved, when paving reaches the preset extent, coverage on the wellhead is removed, the wellbore is in butt joint with the wellhead, and road surface paving continues being conducted outside the wellbore. According to the wellbore installingmethod, the wellbore and the well lid are prefabricated into a whole, the quality intensity is improved, the appearance is beautiful, the height of the wellhead is obtained through calculating, it can be effectively ensured that the wellbore is right flush with the road surface after being installed, the overall flatness of the road surface is improved, the wellbore can adapt to road surfaces different in forms, the cost is reduced, energy is saved, and energy wasting is avoided.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a shaft installation method. Background technique [0002] Generally speaking, the main road structure on site is divided into subgrade, gravel cushion, cement stabilized gravel base and asphalt surface. When paving the cement-stabilized macadam base and asphalt surface, it is necessary to use a road roller for compaction after paving. In the construction of the inspection well, if the wellbore is installed in advance, it will cause difficulties in paving and compaction around the wellbore. If the cast-in-place method is used, there will be multi-stage construction problems, the quality will not meet the requirements, and the construction period will be longer. , so prefabricated shafts are generally used and installed before the last layer of asphalt surface is paved. [0003] When installing a prefabricated well shaft, it is generally only necessary to ensure th...
