[0023] When the inner plug-in ring 7 is inserted into the outer plug-in ring 6, the first bonding layer 9 formed by the first concrete adhesive can play a role in bonding the upper end face of the inner plug-in ring 7 to the lower end face of the annular structure 1.

[0031] The plug-in protrusion 4 is arranged at the middle position of the end of one of the semi-ring structures 2, and is approximately in the middle position in height, so as not to affect the arrangement of the inner plug-in ring 7 and the outer plug-in ring 6 on the annular structure. Moreover, based on this arrangement, the plug-in protrusion 4 and the plug-in groove 5 can play a positioning role, so that the two semi-ring structures can be aligned in both the horizontal and vertical directions.

[0032] To summarize, the utility model decomposes the inspection well into multiple annular structures, each of which is further divided into two semi-ring structures. The two semi-ring structures are positioned by means of plug-in protrusions and plug-in grooves, and the annular structures are connected by means of inner plug-in rings and outer plug-in rings, thereby improving the positioning accuracy between the various components of the inspection well, thereby reducing the assembly difficulty of the prefabricated inspection well, and improving the assembly efficiency and assembly accuracy of the prefabricated inspection well.
