[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figure 1 and Figure 2 As shown, the vertical shaft drainage system of the embodiment of the present invention includes a vertical shaft body 1, a plurality of first water collectors 2 and a second drainage pipe 3 drainage assembly, the vertical shaft body 1 includes a plurality of vertical shaft sections 11, the plurality of vertical shaft sections 11 are sequentially connected along the length direction of the vertical shaft body 1 and are connected to each other, the first water collector 2 surrounds the vertical shaft section 11, and the plurality of first water collectors 2 are connected to the plurality of vertical shaft sections 11 one by one.

[0025] The drainage assembly is connected to the shaft body 1, and the drainage assembly is respectively connected to a plurality of first water collectors 2, and the other end of the drainage assembly is connected to the outside.

[0026] like Figure 1 and Figure 2 As shown, a plurality of shaft sections 11 are sequentially connected from top to bottom, and a through hole extending in the up-down direction is provided inside the shaft section 11 . The through holes inside the plurality of shaft sections 11 are connected to each other to form the inner wall surface of the shaft body 1 .

[0027] The outer wall surfaces of the plurality of shaft sections 11 are flush with each other, and the inner wall surfaces of the plurality of shaft sections 11 are flush with each other.

[0028] The cross section of the shaft section 11 may be circular or rectangular. The multiple shaft sections 11 have the same size, that is, when the shaft section 11 is cylindrical, the inner diameter and outer diameter of the multiple shaft sections 11 are the same.

[0029] The first water collector 2 is wound around the shaft section 11. The first water collector 2 is used to collect seepage water on the wall of the shaft section 11. Multiple first water collectors 2 collect the collected seepage water into the second drain pipe 3 and discharge it from the shaft through the second drain pipe 3. Multiple water collectors are arranged in parallel with each other, and multiple first water collectors 2 are evenly spaced in the up and down directions to ensure the uniformity of seepage water collection for each shaft section 11. The first water collector 2 is arranged horizontally to avoid accumulation of seepage water in the first water collector 2 in the first water collector 2, or the first water collector 2 is slightly tilted toward the connection between the first water collector 2 and the drainage assembly of the second drain pipe 3, so that the seepage water in the first water collector 2 can be quickly converged into the drainage assembly of the second drain pipe 3. Multiple first water collectors 2 collect the seepage water into the drainage assembly, and discharge the seepage water from the second drain pipe 3 of the shaft through the drainage assembly.

[0030] The vertical shaft drainage system of the embodiment of the present invention can collect seepage water on the vertical shaft body 1 through the first water collector 2 and discharge it out of the vertical shaft through the second drainage pipe 3 of the drainage component, thereby preventing and draining the seepage water in the vertical shaft and improving the strength of the vertical shaft.

[0031] In some embodiments, the first water collector 2 is located at the connection between two adjacent shaft sections 11 .

[0032] Specifically, Figure 2 As shown, the installation position of the first water collector 2 is located at the connection of the two shaft sections 11, so that the seepage at the connection of the two shaft sections 11 can be collected in the first water collector 2, thereby improving the water seepage prevention effect at the connection of the shaft sections 11 and the water seepage prevention effect of the entire shaft body 1.

[0033] In some embodiments, the drainage assembly includes a first drain pipe 6, a second drain pipe 3 and a second water collector 5, the second drain pipe 3 is respectively connected to multiple first water collectors 2, one end of the second water collector 5 is connected to the second drain pipe 3, and the other end of the second water collector 5 is connected to the first drain pipe 6.

[0034] Specifically, Figure 2 and Figure 3 As shown, the first drain pipe 6 and the second drain pipe 3 both extend in the up and down directions, the second drain pipe 3 is connected with multiple first water collectors in sequence, the second water collector 5 is located at the lower end of the second drain pipe 3, the second water collector 5 surrounds the vertical shaft section 11, the first drain pipe 6 is connected with the second water collector 5, and the outlet of the first drain pipe 6 extends out of the vertical shaft body.

[0035] Specifically, Figure 2 As shown, the second water collector 5 is connected to the bottom of the second drain pipe 3, the first drain pipe 6 is connected to the second water collector 5, the first drain pipe 6 is arranged in the vertical shaft section 11, and the first drain pipe 6 is arranged in parallel with the second drain pipe 3. By setting the second water collector 5, the seepage water in the second drain pipe 3 can be collected and discharged from the vertical shaft through the first drain pipe 6. The first drain pipe 6 is located in the vertical shaft section 11, which is convenient for replacing the first drain pipe 6.

[0036] In some embodiments, the vertical shaft drainage system further includes a plurality of injection pipes 4 , which surround the outside of the vertical shaft section 11 , and the plurality of injection pipes 4 correspond one-to-one to the plurality of vertical shaft sections 11 .

[0037] For example, multiple injection pipes 4 are connected to each other, and water sealing material is injected into the shaft body 1 through the injection pipes 4, thereby improving the sealing of the shaft body 1 and preventing water seepage in the shaft. By providing multiple injection pipes 4, the injection efficiency and uniformity of the water sealing material can be improved.

[0038] In some embodiments, the vertical shaft drainage system further includes a waterstop 7 , which is wrapped around the connection between the inner shafts 112 of two adjacent vertical shaft sections 11 .

[0039] Specifically, Figure 2As shown, the waterstop 7 is covered on the inner side of the shaft section 11, and the waterstop 7 is covered on the connection between two adjacent shaft sections 11. The size of the waterstop 7 in the up and down direction is larger than the size of the connection between the two adjacent shaft sections 11 in the up and down direction, ensuring that the waterstop 7 completely covers the connection between the two adjacent shaft sections 11, avoiding water seepage at the connection of the inner shaft 112, and improving the structural stability of the shaft body 1.

[0040] Specifically, Figure 2 As shown, the water stop 7 is coated on the inner side of the shaft section 11, and the seepage water first enters the first water collector 2, which can further prevent the seepage water from entering the interior of the shaft body 1, thereby improving the dryness and cleanliness of the shaft. In addition, by providing the water stop 7, the connection of the shaft section 11 can be sealed, thereby improving the sealing of the connection of the shaft section 11 and preventing the seepage water from entering the interior of the shaft through the connection.

[0041] In some embodiments, the vertical shaft drainage system further includes a waterproof board 8 , which is coated at the connection between two adjacent vertical shaft sections 11 , and the waterproof board 8 is located on the outside of the vertical shaft section 11 .

[0042] Specifically, Figure 2 As shown, the waterproof board 8 is wrapped around the connection between two adjacent shafts, and the outer wall surface of the waterproof board 8 is flush with the outer wall surface of the shaft section 11, so as to avoid the accumulation of seepage water at the connection between the waterproof board 8 and the shaft section 11, thereby avoiding the formation of a high-depth water-conducting channel.

[0043] The vertical shaft drainage system of the embodiment of the present invention prevents water from seeping into the connection between the vertical shaft sections 11 by providing a waterproof plate 8, thereby improving the waterproofness of the vertical shaft.

[0044] In some embodiments, the shaft drainage system further includes a waterproof layer 9 , which is sprayed on the inner wall surface of the shaft section 11 .

[0045] Specifically, Figure 2 As shown, the waterproof layer 9 is sprayed on the inner wall surface of the shaft section 11. By spraying the waterproof layer 9, the flatness and waterproofness of the inner wall surface of the shaft section 11 can be improved. If water seepage occurs, it is also convenient for later maintenance.

[0046] In some embodiments, when water seepage occurs in the shaft, a drainage pipe 10 may be provided, one end of which is connected to the water seepage area, and the other end of the drainage pipe 10 is connected to the first drainage pipe 6, so as to discharge the water seepage from the water seepage area.

[0047] In some embodiments, the vertical shaft section 11 includes an inner well 112 and an outer well 111, the outer well 111 is arranged outside the inner well 112, the first water collector 2 and the second drainage pipe 3 are arranged between the outer well 111 and the inner well 112, and multiple first water collectors 2 are arranged at intervals in the length direction of the vertical shaft body 1, and the second drainage pipe 3 extends along the length direction of the vertical shaft body 1 to connect multiple first water collectors 2.

[0048] Specifically, Figure 3 As shown, the outer well 111 is located outside the inner well 112, and the first water collector 2 and the second drainage pipe 3 are both located between the inner well 112 and the outer well 111. Placing the first water collector 2 and the second drainage pipe 3 between the inner well 112 and the outer well 111 can not only improve the service life of the first water collector 2 and the second drainage pipe 3, but also prevent water from seeping from the inner well 112 into the outer well 111, reduce the permeability of the seepage water, and improve the structural stability of the shaft body 1.

[0049] Specifically, Figure 3 As shown, when the shaft section 11 includes an inner shaft 112 and an outer shaft 111, the injection pipe 4 is arranged between the inner shaft 112 and the outer shaft 111, and the water-sealing material can be injected between the inner shaft 112 and the outer shaft 111 through the injection pipe 4, thereby improving the sealing of the shaft body 1 and preventing water seepage in the shaft. By setting a plurality of injection pipes 4, the injection efficiency and uniformity of the water-sealing material can be improved. The water stop 7 is coated at the connection between two adjacent inner shafts 112, and the water stop 7 is arranged adjacent to the inner shaft 112 relative to the first water collector 2.

[0050] Specifically, Figure 2 As shown, the waterstop 7 is covered on the outside of the inner well 112, and the waterstop 7 is covered on the connection between two adjacent inner wells 112. The size of the waterstop 7 in the up and down direction is larger than the size of the connection between the two adjacent inner wells 112 in the up and down direction, ensuring that the waterstop 7 completely covers the connection between the two adjacent inner wells 112, avoiding water seepage at the connection between the inner wells 112, and improving the structural stability of the vertical shaft body 1.

[0051] The water stop 7 is coated on the outer wall of the inner well 112, and the first water collector 2 surrounds the outside of the water stop 7. The water stop 7 is coated on the inner well 112, and the seepage water first enters the first water collector 2, which can further prevent the seepage water from entering the interior of the shaft body 1, thereby improving the dryness and cleanliness of the shaft. In addition, by providing the water stop 7, the connection of the inner well 112 can be sealed, thereby improving the sealing of the connection of the inner well 112 and preventing the seepage water from entering the interior of the shaft through the connection.

[0052] The waterproof board 8 is covered at the connection between two adjacent outer wells 111 .

[0053] Specifically, Figure 3As shown, the waterproof board 8 is wrapped around the connection between two adjacent outer wells 111, and the outer wall surface of the waterproof board 8 is flush with the outer wall surface of the outer well 111, so as to avoid the accumulation of seepage water at the connection between the waterproof board 8 and the outer well 111, thereby avoiding the formation of a high-depth water-conducting channel.

[0054] like Figure 3 As shown, the waterproof layer 9 is sprayed on the inner wall surface of the inner well 112. By spraying the waterproof layer 9, the flatness and waterproofness of the inner wall surface of the inner well 112 can be improved. If water seepage occurs, it is also convenient for later maintenance.

[0055] The shaft construction method of an embodiment of the present invention includes the following steps: casting the shaft section 11, fixing the first water collector 2, the first drainage pipe 6, the second water collector 5, the second drainage pipe 3 and the injection pipe 4 at the connection between two adjacent shaft sections 11, and covering the water stop belt 7.

[0056] For example, when water seepage occurs inside the inner well 112, the wall of the seepage area is chiseled off, and the seepage area is connected to the first drain pipe 6 through the drainage pipe 10, so that the seepage water in the seepage area is introduced into the first drain pipe 6, and then the seepage area is filled with self-expanding material, and the waterproof layer 9 is re-sprayed on the seepage area.

[0057] The vertical shaft construction method of the embodiment of the present invention can quickly and conveniently drain the water seepage area and prevent the water seepage area from continuing to seep water, thereby improving the waterproofness and dryness and cleanliness of the interior of the vertical shaft.

[0058] In the shaft construction method of the embodiment of the present invention, the surrounding rock cannot form a stream of water or a concentrated water-producing layer; at the same time, small-molecule chemical materials should be used for injection of water-sealing materials to ensure the injection sealing effect; the waterproof layer 9 can not only make the internal environment of the shaft beautiful, but also play a role in preventing water seepage and improving the strength of the shaft.
