Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In the invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to the specific circumstances.

[0036] Please refer to Figures 1 to 4dThe prefabricated inspection well includes: a ring beam 1, a first wellbore 2, and a second wellbore 3. One end of the first wellbore 2 is vertically fixed on the ring beam 1, and the other end is sleeved in the second wellbore 3. The first wellbore 2 includes: a first spiral step wellbore 6, a second spiral step wellbore 8, and a plurality of adjustment prefabricated blocks 7. The rotating steps at the edge of the first spiral step wellbore are complementary to the rotating steps at the edge of the second spiral step wellbore. According to the number of remaining steps, a corresponding number of adjustment prefabricated blocks 7 are selected and embedded between the non-complementary steps of the two to fill the gap between the two, and the first wellbore 2 is assembled. The assembled first wellbore 2 is a hollow column.

[0037] Specifically, Figure 1 As shown, the second wellbore 3 is a hollow main body, and there is a gap between one end of the first wellbore 2 , and the gap is filled after the first wellbore 2 and the second wellbore 3 are connected.

[0038] Please refer to Figure 5 Between the rotating step at the edge of the first spiral step shaft 6 of the assembled first shaft 2 and the rotating step at the edge of the second spiral step shaft 8, each increase / decrease of an adjusting prefabricated block 7 can correspondingly increase / decrease the height of the assembled first shaft 2 by one step.

[0039] In this embodiment, two adjustment prefabricated blocks 7 are used to fill the gap between the rotating step at the edge of the first spiral step shaft and the rotating step at the edge of the second spiral step shaft. The specific results are as follows: Figures 2 to 4d If the first shaft 2 is to be increased in height by one step, the second spiral step shaft 8 needs to be fixed first, and the first spiral step shaft 6 needs to be rotated counterclockwise by a predetermined angle, and an adjustment prefabricated block 7 is added at a position adjacent to the adjustment prefabricated block 7 between the second spiral step shaft 8 and the first spiral step shaft 6, so as to increase the height of the first shaft 2 by one step. Figure 5 shown.

[0040] like Figure 1 As shown, the prefabricated inspection well also includes: a first steel bar 4a, a second steel bar 4b and a steel bar sleeve 5. Each second steel bar 4b embedded in the wall of the second shaft 3 and partially exposed is connected to the first steel bar 4a that passes through the wall of the first shaft 2 through the steel bar sleeve 5, so that the first steel bar 4a and the second steel bar 4b are coaxial to fix the first shaft 2 and the second shaft 3 on the ring beam 1.

[0041] Specifically, the wall of the first shaft 2 is provided with steel bar installation holes 9 at uniform intervals along its circumference, and the position of each steel bar installation hole 9 corresponds to the position of the second steel bar 4b embedded in the wall of the second shaft 3; wherein each steel bar installation hole 9 passes through a rotation step on the edge of the first spiral step shaft 6 and a rotation step on the edge of the second spiral step shaft 8 at the corresponding position.

[0042] It can be understood that the diameter of the steel bar installation hole 9 described here is larger than the diameter of the first steel bar 4a, so that the first steel bar 4a passes through the steel bar installation hole 9 on the wall of the first shaft 2 and docks with the second steel bar 4b embedded in the wall of the second shaft 3. A steel bar sleeve 5 is arranged on the plane where the first shaft 2 and the second shaft 3 dock, so as to facilitate the replacement of the first steel bar 4a when the height of the prefabricated inspection well is adjusted, and the first steel bar 4a and the second steel bar 4b are connected as a coaxial whole. Based on the first steel bar 4a being fixed on the ring beam 1, the first shaft 2 and the second shaft 3 are indirectly installed and fixed on the ring beam 1 as a whole, so as to ensure the overall stability and firmness of the prefabricated inspection well. In addition, since the height of each inspection well lifting is fixed, the steel bar length of the first steel bar 4a is also modular, which is convenient for manufacturing.

[0043] Better, such as Figure 1 As shown, a thread is provided on the outer side of one end of each first steel bar 4a adjacent to the ring beam 1, and one end of the first shaft 2 is vertically fixed to the ring beam 1 by a nut cooperating with the thread on the first steel bar 4a.

[0044] Accordingly, this embodiment also provides a construction method for a prefabricated inspection well. Figures 1 to 5 The construction method of the prefabricated inspection well described in this embodiment is described in detail.

[0045] First, execute step S1 to determine the current sinking and floating conditions of the inspection well, and carry out corresponding steps according to the sinking and floating conditions;

[0046] Next, step S2 is executed. When the inspection well sinks and needs to be lifted, the second spiral step shaft 8 is fixed, and the first spiral step shaft 6 is rotated counterclockwise by a predetermined angle, and a corresponding number of adjustment prefabricated blocks 7 are added between the second spiral step shaft 8 and the first spiral step shaft 6 to increase the height of the first shaft 2;

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

[0048] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0049] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
