DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] For example, see Figures 1 to 6 The utility model provides a prefabricated vertical shaft structure, comprising:

[0028] Multiple groups of well bodies, each group of well bodies includes a plurality of well plates 1, the well plates 1 are arranged in an arc shape, and a slot 101 is opened on one side of the well plate 1, and an insert block 2 is fixedly connected to the other side, and the insert block 2 is adapted to the slot 101;

[0029] Steel bars 4 are arranged in the well segments 1, and vertically adjacent well segments 1 are connected by the steel bars 4 through the constrained slurry anchor connection technology. Each group of well bodies is arranged in a circular shape, and a sealing ring 6 is arranged at the connection between the two groups of well bodies.

[0030] The limiting rod 7 and the well plate 1 are provided with a through hole on the surface thereof for the limiting rod 7 to extend into and be slidably connected thereto. The end of the limiting rod 7 is located in the slot 101. The surface of the insert block 2 is provided with a limiting groove 201 for the limiting rod 7 to extend into. A locking component is provided between the limiting rod 7 and the insert block 2 for limiting the limiting rod 7.

[0031] In this embodiment, the well piece 1 is produced in the factory and assembled on site when in use. The plug block 2 on the surface of the well piece 1 is aligned with the slot 101 opened on the surface of another well piece 1 and then inserted. Specifically, it can be plugged in from top to bottom by hoisting until the bottom of the plug block 2 abuts against the bottom of the inner wall of the slot 101, and then the limit rod 7 is inserted into the limit groove 201 and limited by the locking component. The above steps are repeated until a circular well body is formed. Finally, the steel bar 4 is used for longitudinal connection. Then, the number of well bodies can be calculated in advance according to the required vertical well height, so as to obtain the number of well pieces 1 required. By using prefabricated well pieces 1 for on-site assembly, there is no need to tie steel bars, support formwork, pour concrete, etc. at the construction site. At the same time, there is no need to repeatedly twist bolts, which greatly saves time and improves the installation efficiency of the vertical well.

[0032] The locking components include:

[0033] The card block 10, the inner wall of the limiting groove 201 is provided with a card slot 2011 for the card block 10 to extend into, the surface of the limiting rod 7 is provided with a groove 702 for the card block 10 to extend into, and a spring 11 is fixedly connected between the groove 702 and the card block 10, and the card block 10 is plate-shaped and has an arc-shaped end;

[0034] A steering limit assembly is arranged on the surface of the well plate 1 and is used to limit the rotation of the limit rod 7 .

[0035] In this embodiment, after the two well plates 1 are connected, the plug block 2 is inserted into the slot 101, and the limit rod 7 is pushed to extend into the deepest part of the limit groove 201, and then the limit rod 7 is rotated. The limit rod 7 is rotated to drive the block 10 to slide on the inner wall of the limit groove 201, and at the same time, pressure is applied to the spring 11 to shrink it until the block 10 is aligned with the groove 2011. The spring 11 is no longer under pressure, and the elastic restoring force of the spring 11 drives the block 10 to extend into the groove 2011, thereby fixing the limit rod 7. The installation can be completed by limiting the rotation of the limit rod 7 through the steering limit assembly. There is no need to use bolts, which saves time and improves the efficiency of vertical well installation.

[0036] During disassembly, first release the limit on the limit rod 7 through the steering limit assembly, and then rotate the limit rod 7 to drive the block 10 to rotate. Since the block 10 is in a plate shape and the end is arc-shaped, it will be pressed into the groove 702 during the rotation process. When the block 10 is separated from the slot 2011, the limit rod 7 can be pulled out of the limit slot 201, thereby releasing the limit on the plug block 2 for subsequent disassembly.

[0037] The steering limit assembly includes a handle 8, and two symmetrically distributed U-shaped blocks 9 are fixedly connected to the surface of the well plate 1. The surface of the U-shaped block 9 is provided with a sliding groove for the handle 8 to be inserted into and slidably connected thereto, and the surface of the limit rod 7 is provided with a groove 701 for the handle 8 to be inserted into and slidably connected thereto.

[0038] In this embodiment, the handle 8 is arranged to slide in the slot 701. Figure 2 and Figure 5 As shown, at this time, the block 10 is in the slot 2011, and the handle 8 is located in the slide groove opened on the surface of the U-shaped block 9. At this time, the handle 8 cannot be rotated. When it needs to be rotated, the handle 8 is pulled to slide in the slot 701 to separate it from the slide groove, and then it can be rotated, thereby avoiding the shaking of the limit rod 7 during use and improving the stability of the vertical well after installation.

[0039] In the second embodiment, further, the number of the blocks 10 is two and they are symmetrically distributed, the number of the locking components is at least two groups and they are evenly distributed on the surface of the well plate 1, and by providing two symmetrically distributed blocks 10 and at least two groups of locking components, the force on the plug 2 is more evenly applied, thereby improving the stability during use.

[0040] A mounting block 3 is fixedly connected to the upper surface of the well plate 1, and a mounting groove 102 is provided on the lower surface of the well plate 1. The mounting block 3 is adapted to the mounting groove 102, and sealing gaskets are provided in the mounting groove 102 and the slot 101. By providing the mounting block 3 and the mounting groove 102, each well plate 1 can be more conveniently aligned during hoisting and installation, and the insertion of the mounting block 3 into the mounting groove 102 can further improve the stability of the well plate 1.

[0041] A plurality of ladders 5 are evenly distributed on the inner wall of one of the well plates 1, and the ladders 5 in each group of the well bodies are at the same position. By providing the ladders 5, it is convenient for the staff to move in the well body for subsequent maintenance.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
