Abstract

The invention provides a method for installing a wellbore, which comprises the following steps: a prefabricating step of prefabricating a wellbore with a first preset height, and prefabricating a well cover at the end of the wellbore; Cover and mark the wellhead at a preset height; the wellhead is set on the top of the well chamber and communicates with the inside of the well chamber, and the sum of the first preset height and the second preset height is the distance between the top of the well chamber and the road surface distance; installation steps, laying the road surface, and removing the cover of the wellhead when laying to a preset level, connecting the wellbore to the wellhead, and continuing to pave the road outside the wellbore. In the present invention, the well shaft and the well cover are prefabricated into one body, which improves the quality and strength, and the appearance is beautiful. The height of the well head is calculated, which can effectively ensure that the well shaft is just flush with the road surface after installation, and improves the overall flatness of the road surface. , and can be applied to different forms of road surfaces, reducing costs, saving resources, and avoiding waste of resources.

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...
