[0002] An inspection well is a structure used for inspecting, maintaining and managing underground pipelines, cables and other facilities. It is usually a well-shaped structure arranged at the intersection of a pipeline system, a turning point or a position requiring maintenance. The purpose of the design of the inspection well is to facilitate the entry of engineering personnel into the well, to check the state of the pipeline, to clean the blockage, to carry out maintenance or to install new equipment.

[0003] The inspection well is supported and poured into shape by a formwork during pouring. An outer mold and an inner mold are used in cooperation to pour concrete between the inner and outer molds to form the structure of the inspection well. However, the concentricity of the placement of the inner and outer molds directly determines the molding effect of the concrete after pouring. In particular, when the bottom end of the inner mold is pressed from a single side by a large amount of concrete, the bottom end of the inner mold is prone to tilting, which may cause problems in the pouring of the inspection well.
