The rib 1123 near one end of the tube sheet 112 encloses a first groove-shaped space 111A with one end of the first web 1121 and one end of the second web 1122, and the rib 1123 near the other end of the tube sheet 112 opposite to the one end encloses a second groove-shaped space 111B with the other end of the first web 1121 and the other end of the second web 1122. Specifically, the tube sheet 112 has two opposite ends along the circumferential direction, and the rib 1123 at one end of the tube sheet 112 and the first web 1121 and the second web 1122 of the tube sheet 112 enclose to form an open groove, i.e., the first groove-shaped space 111A; the ribs 1123 at the other end of the tube sheet 112 and the first and second webs 1121, 1122 of the tube sheet 112 also enclose an open groove, i.e., the second groove-shaped space 111B. The opening directions of the first groove-shaped space 111A and the second groove-shaped space 111B are opposite.

As shown in fig. 5B, the first groove-shaped spaces 111A and the second groove-shaped spaces 111B of the adjacent segments 112 collectively form the second through holes 1112. Specifically, two adjacent pipe pieces 112 are assembled and connected, so that the first groove-shaped space 111A at one end of one pipe piece 112 is spliced with the second groove-shaped space 111B at one end of the other pipe piece 112, and thus the two open grooves form a circumferentially continuous cavity, which is the second through hole 1112. In other embodiments, the shape and size of the first through-hole 1111 and the second through-hole 1112 may be the same.

The second through hole 1112 is formed by splicing two semi-open groove-shaped spaces, a connecting seam can exist at the splicing position of the second through hole 1112, the connecting seam is located on a cast-in-place belt, a reinforcing member 12 is arranged in the second through hole 1112, and the reinforcing member 12 can fill and cover the connecting seam to reduce the risk of rainwater infiltration and enable the vertical shaft 10 to have a waterproof function through the structure of the vertical shaft 12. The shaft 10 thus does not need any further waterproofing measures.

In some embodiments, the shape and structure of the adjacent segments 112 may be the same or different, for example, as shown in fig. 5c, and each segment 112 is the same, so that the segment rings 11 can be assembled by prefabricating only one structure of the segments 112, and there is no need to prefabricating multiple structure types of the segments 112, thereby simplifying the preparation process of construction raw materials. As shown in fig. 5B, the two adjacent tube sheets 112 have different shapes and structures, and include a first tube sheet 112A and a second tube sheet 112B, and the first tube sheet 112A and the second tube sheet 112B are alternately arranged in the circumferential direction. Specifically, each segment ring 11 includes two types of segment 112 to increase the flexibility of assembly of the segments 112. The following description is for the tube sheet 112 having two different types of structures.

As shown in fig. 5B, the first through holes 1111 of the first tube sheet 112A and the first through holes 1111 of the second tube sheet 112B extend in the circumferential direction to the same length. Specifically, the adjacent ribs 1123 of the first tube sheet 112A are spaced apart by a distance that is substantially the same as the distance that is spaced apart by the adjacent ribs 1123 of the second tube sheet 112B. The radial distance between the first web 1121 and the second web 1122 of the first tube sheet 112A is substantially equal to the radial distance between the first web 1121 and the second web 1122 of the second tube sheet 112B, the adjacent first webs 1121 are connected end to form an outer ring of the tube sheet ring 11, and the adjacent second webs 1122 are connected end to form an inner ring of the tube sheet ring 11. Thus, the first through holes 1111 of the first tube sheet 112A and the first through holes 1111 of the second tube sheet 112B are also substantially the same in shape and size.

As shown in FIG. 5B, the first groove-shaped spaces 111A of the first tube sheet 112A and the first groove-shaped spaces 111A of the second tube sheet 112B have different lengths in the circumferential direction and/or the second groove-shaped spaces 111B of the first tube sheet 112A and the second groove-shaped spaces 111B of the second tube sheet 112B have different lengths in the circumferential direction. Specifically, the first groove-shaped space 111A of the first tube sheet 112A and the second groove-shaped space 111B of the second tube sheet 112B enclose to form the second through hole 1112, and the ratio of the extension length of the first groove-shaped space 111A to the extension length of the second groove-shaped space 111B in the circumferential direction may also be changed. That is, in the circumferential direction, the lengths of the first groove-shaped spaces 111A and the second groove-shaped spaces 111B of the two tube sheets 112 are both different, or the lengths of the first groove-shaped spaces 111A and the lengths of the second groove-shaped spaces 111B of the two tube sheets 112 are the same. The specific setting can be according to actual need.

The reinforcement cage 122 is disposed within the second through-hole 1112. Specifically, in order to strengthen the connection relationship between the end portions of two adjacent segments 112, the steel reinforcement cage 122 may be disposed in the second through hole 1112, and then concrete may be poured into the second through hole 1112 to form a reinforced concrete structure, so as to effectively improve the structural rigidity of the end connection portion, and further improve the overall supporting capability of the shaft 10.

The first and second ramps 112E, 112F are inclined along the same side so that adjacent second webs 1122 can abut through the ramps to provide a supporting force. The second webs are provided with the inclined planes, and the adjacent second webs are connected in an inclined plane butt joint mode, so that the connection of the adjacent segments is realized.

Optionally, as shown in fig. 10, positioning holes are reserved on the first inclined surface 112E and the second inclined surface 112F, and the fastening member 114 is inserted into the positioning holes to further strengthen the connection between the first inclined surface 112E and the second inclined surface 112F.

Before the shaft of the embodiment of the utility model is constructed, a plurality of duct pieces can be prefabricated in a factory to be reserved for construction; adopting a heading machine to excavate on the ground to form a hole body for placing a vertical shaft, and installing and placing a supporting plate above the heading machine according to a measurement result, wherein the supporting plate can gradually move downwards along the wall of the hole along with the continuous excavation of the heading machine; assembling pipe pieces on the ground to form a plurality of pipe piece rings, then sequentially lifting each pipe piece ring in the hole body, enabling the through holes to be in one-to-one correspondence, keeping the through holes to be communicated with each other, lowering the pipe piece ring on the lowest layer onto the bearing plate, and stacking the rest pipe piece rings in a layered manner; continuously putting the segment rings by adopting an open caisson method, and integrally sinking all the assembled segment rings; after excavating to a preset depth, reinforcing and leveling the bottom of the hole body, and then putting down all assembled pipe sheet rings; placing a steel reinforcement cage in the second through hole, and then pouring plain concrete in the first through hole and the second through hole to fill the through holes; and finally, grouting and backfilling a gap between the duct piece and the wall of the hole, and forming a locking structure at the position of a well head in a cast-in-place mode, so that the construction of the whole vertical shaft is completed, and a permanent vertical shaft supporting structure is formed.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
