[0036] Reference should be made to Figures 1 to 4d, the prefabricated inspection well comprises: a ring beam 1, a first well shaft 2, and a second well shaft 3, one end of the first well shaft 2 is fixed vertically on the ring beam 1, and the other end is sleeved in the second well shaft 3; wherein the first well shaft 2 comprises: a first spiral stepped well shaft 6, a second spiral stepped well shaft 8, and a plurality of adjusting prefabricated blocks 7, the rotation steps of part of the edges of the first spiral stepped well shaft are complementary to the rotation steps of the edges of the second spiral stepped well shaft; according to the number of the remaining steps, a corresponding number of adjusting prefabricated blocks 7 are selected and embedded between the non-complementary steps to make up the gap between them, thereby assembling the first well shaft 2. The assembled first well shaft 2 is a hollow cylinder.

[0037] Specifically, as shown in Figure 1 , the second well shaft 3 is a hollow body with a gap at one end of the first well shaft 2, and the gap is filled after the first well shaft 2 and the second well shaft 3 are connected.

[0038] Please refer to Figure 5 , between the rotation steps of the edges of the first spiral stepped well shaft 6 and the edges of the second spiral stepped well shaft 8 of the assembled first well shaft 2, for every added / decreased adjusting prefabricated block 7, the height of the assembled first well shaft 2 can be increased / decreased by one step height.

[0039] This embodiment uses two adjusting prefabricated blocks 7 to make up the gap between the rotation steps of the edges of the first spiral stepped well shaft and the edges of the second spiral stepped well shaft, and the specific result is shown in Figures 2 to 4d . If it is desired to increase the height of the first well shaft 2 by one step, the second spiral stepped well shaft 8 is first fixed, the first spiral stepped well shaft 6 is rotated counterclockwise by a predetermined angle, and an adjusting prefabricated block 7 is added at the position adjacent to the adjusting prefabricated block 7 between the second spiral stepped well shaft 8 and the first spiral stepped well shaft 6, so that the height of the first well shaft 2 is increased by one step, as shown in Figure 5 .

[0047] When the inspection well needs to be lowered, the second spiral stepped shaft 8 is fixed, the first spiral stepped shaft 6 is rotated clockwise by a predetermined angle, and a corresponding number of adjusting prefabricated blocks 7 are reduced between the second spiral stepped shaft 8 and the first spiral stepped shaft 6 to reduce the height of the first shaft 2.
