Abstract
Description
Technical Field
[0001] The present application relates to the field of vertical shaft drainage, and in particular to a three-stage pumping and drainage system for ultra-deep shafts in railway tunnels. Background Art
[0002] During shaft construction, the presence of groundwater can cause the underground working environment to become humid, which not only affects the health of construction workers but can also adversely affect the normal operation of construction equipment. Therefore, vertical shaft drainage is often necessary to effectively reduce humidity underground and provide a relatively dry and comfortable working environment for construction workers.
[0003] The operation of pumping and draining water in the vertical shaft is usually divided into three stages. The first stage is to set up a first-stage temporary pumping station at the horse head gate space when the shaft reaches the bottom. The second stage is to set up a second-stage temporary pumping station at the slag transfer yard after a certain space is formed by underground excavation. The third stage is to set up a third-stage permanent pumping station in the pump room after the pump room is formed. Through the three-stage drainage setting, the water in the vertical shaft can be steadily discharged to the outside of the well.
[0004] During the drainage process at each stage, one end of the drainage pipe used for drainage is usually set outside the well so that the water in the vertical well can be discharged to the outside through the water pump and the drainage pipe. When the vertical well is very deep and the drainage pipe is very long, the drainage pipe is easily affected by external forces and shakes, which makes it difficult to ensure the stability of the drainage pipe during drainage.

[0033] The following is combined with Figure 1-3 This application is described in further detail.
[0034] The present application discloses a three-stage pumping and drainage system for an ultra-deep well in a railway tunnel. Figure 1 The three-stage pumping and drainage system for ultra-deep shafts in railway tunnels includes a water storage module and a drainage module, wherein the water storage module includes a submersible pump 1, a water storage pipe 2 and a water storage tank 3, wherein the submersible pump 1 is placed in the area to be drained in the shaft, one end of the water storage pipe 2 is installed at the output end of the submersible pump 1, and the other end is installed at the input end of the water storage tank 3, so as to discharge the water in the area to be drained at the bottom of the well into the water storage tank 3 through the submersible pump 1 and the water storage pipe 2.
[0035] The drainage module includes a drainage pump 4, a delivery pipe 5, a drainage pipe 6, a first drainage fixing mechanism and a second drainage fixing mechanism, wherein one end of the delivery pipe 5 is installed at the output end of the water tank 3, and the other end is installed at the input end of the drainage pump 4; one end of the drainage pipe 6 is installed at the output end of the drainage pump 4, and the other end passes through to the outside of the vertical shaft, so that the water collected in the water tank 3 is discharged to the outside of the well through the delivery pipe 5 and the drainage pipe 6 through the drainage pump 4.
[0036] Continue to refer to Figure 1 The drainage pipe 6 includes an inclined drainage section 601 and multiple vertical drainage sections 602 arranged in the vertical direction. One of the vertical drainage sections 602 near the bottom is connected and installed on the top of the inclined drainage section 601. The inclined drainage section 601 is arranged parallel to the inclined inner wall of the vertical shaft, and the vertical drainage section 602 is arranged close to the vertical inner wall of the vertical shaft. The arrangement of the inclined drainage section 601 and the vertical drainage section 602 facilitates the stable discharge of water.
[0037] Reference Figure 1 and Figure 2 The first drainage fixing mechanism is used to fix the inclined drainage pipe 6. Specifically, the first drainage mechanism includes a first base 7, an assembly seat 8, two clamping plates 9 and a driving assembly, wherein the first base 7 includes a fixing cylinder 701 and a fixing rod 702. The end of the fixing cylinder 701 away from the fixing rod 702 is fixedly connected to the fixing base plate 10. The fixing base plate 10 is fixed to the inclined inner wall of the shaft by four bolts distributed in a rectangular shape. The fixing rod 702 slides and fits on the end of the fixing cylinder 701 away from the fixed base plate 10. The fixing rod 702 is tightly fixed to the fixing cylinder 701 by a fixing bolt 703 that is threadedly fitted with the fixing cylinder 701, so that the fixing rod 702 can slide along the axis of the fixing cylinder 701 and achieve a firm fixation with the fixing cylinder 701.
[0038] Reference Figure 2To further ensure the stability of the fixed rod 702 during sliding, a guide bar 11 is fixedly mounted on the fixed rod 702. The fixed cylinder 701 has a guide groove 12 that is connected to the interior of the fixed cylinder 701 at one end facing the fixed rod 702. The guide bar 11 slides and fits within the guide groove 12 to limit the sliding of the fixed rod 702. The assembly seat 8 is fixedly mounted on the end of the fixed rod 702 away from the fixed cylinder 701. This allows the distance between the assembly seat 8 and the inclined inner wall of the shaft to be adjusted when the fixed rod 702 slides along the fixed cylinder 701 and is fixed.
[0039] Continue to refer to Figure 2 The side of the assembly seat 8 away from the fixed rod 702 is provided with a clamping groove 13 extending in a direction perpendicular to the axis of the inclined drainage section 601. The two clamping plates 9 are slidably fitted in the clamping groove 13. The driving component is used to drive the two clamping plates 9 to move toward or away from each other. Specifically, the driving component includes a bidirectional screw rod 14 rotatably installed on the assembly seat 8. The two ends of the bidirectional screw rod 14 are screwed in opposite directions and are respectively passed through the two clamping plates 9 in a direction perpendicular to the axis of the inclined drainage section 601 and threadedly fitted with the clamping plates 9, so that when the bidirectional screw rod 14 rotates, the two clamping plates 9 move toward or away from each other, so that when the inclined drainage section 601 is located between the two clamping plates 9, the inclined drainage section 601 is clamped and fixed by the two clamping plates 9.
[0040] Reference Figure 1 and Figure 2 To further ensure the stability of the clamping plates 9 when clamping the inclined drainage section 601, the adjacent sides of the two clamping plates 9 are both curved to further limit the position of the inclined drainage section 601. To facilitate the application of force to rotate the bidirectional screw rod 14, one end of the bidirectional screw rod 14 is inserted into the outside of the assembly seat 8 and fixedly connected to the rotation handle 15.
[0041] Reference Figure 1 and Figure 3 The second drainage fixing mechanism is used to fix the vertically arranged drainage pipe 6. Multiple second drainage fixing mechanisms are provided in a one-to-one correspondence with the vertical drainage section 602. Specifically, the second drainage fixing mechanism includes a second base 16, which includes a mounting base 161 and a mounting frame 162. The mounting base 161 is provided with four rectangular strip holes 17, which are all provided through and extend in the vertical direction. Multiple groups of mounting bolts 18 corresponding to each mounting base 161 are pre-embedded and fixed on the inner wall of the vertical shaft. Each group of mounting bolts 18 has four mounting bolts 18 corresponding to each strip hole 17. Each mounting bolt 18 in each group is respectively inserted into each strip hole 17 to achieve a stable fixation between the mounting base 161 and the vertical inner wall of the vertical shaft. The provision of the strip holes 17 facilitates fine-tuning of the height position of the second base 16.
[0042] Reference Figure 3 The mounting bracket 162 is fixedly mounted on the side of the mounting base plate 161 away from the vertical inner wall of the shaft. A mounting slot 19 is defined on the side of the mounting bracket 162 away from the mounting base plate 161 for the vertical drainage section 602 to pass through. Reinforcing ribs 20 are fixedly mounted on the outer circumference of each vertical drainage section 602. The reinforcing ribs 20 include rib plates 201 and reinforcing base plates 202. Multiple rib plates 201 are evenly distributed circumferentially around the axis of the vertical drainage section 602. The reinforcing base plates 202 are fixedly mounted to the bottom plates of each rib plate 201. When the vertical drainage section 602 is located within the mounting slot 19, the reinforcing base plates 202 of the reinforcing ribs 20 abut against the top of the second base 16, providing stable support for the vertical drainage section 602.
[0043] Continue to refer to Figure 3 A stopper slot 21 is formed on one side of the mounting frame 162 and is connected to the mounting slot 19. A stopper plate 22 slidably engages within the stopper slot 21. Specifically, the stopper plate 22 includes a horizontal portion 221 and a vertical portion 222. The horizontal portion 221 slidably engages within the stopper slot 21, while the vertical portion 222 is fixedly connected to one end of the horizontal portion 221. The vertical portion 222 is secured to the mounting frame 162 via bolts. When the vertical drain section 602 is located within the mounting slot 19, it is located within the area enclosed by the mounting slot 19 and the horizontal portion 221 of the stopper plate 22. This allows the stopper plate 22 to further limit the position of the vertical drain section 602, thereby further ensuring the stability of the position of the vertical drain section 602.
[0044] The implementation principle of the three-stage pumping and drainage system for an ultra-deep and solid shaft in a railway tunnel according to an embodiment of the present application is as follows: during the drainage process, the water in the area to be drained in the vertical shaft is first transported to the water storage tank 3 by the submersible pump 1, and then the water in the water storage tank 3 is transported out of the shaft through the delivery pipe 5 by the drainage pump 4. During the transportation of the drainage pipe 6, the clamping effect of the two plywood 9 on the inclined section of the drainage pipe 6 is conducive to ensuring the stability of the inclined section of the drainage pipe 6 during transportation, and the supporting effect of the mounting frame 162 on the vertical section of the drainage pipe 6 is conducive to ensuring the stability of the vertical section of the drainage pipe 6 during transportation, thereby facilitating the stable drainage of the area. In addition, the arrangement of the water storage tank 3 during the drainage process can, on the one hand, deposit the discharged water and reduce the blockage of the drainage pipe 6 by the sediment; on the other hand, it is conducive to ensuring the water level stability during drainage, thereby facilitating the stable drainage of the well.
[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
