Description

Technical Field

[0001] This invention relates to the technical field of water conservancy engineering. More specifically, this invention relates to a collection device for seepage water from the walls of vertical shafts. Background Technology

[0002] In water diversion tunnel systems, ventilation shafts are typically installed to facilitate air venting and replenishment during operation. In cold regions, shaft structures are susceptible to seepage water: when seepage water repeatedly freezes and thaws inside or on the surface of the shaft, it generates significant expansion stress, leading to concrete cracking and spalling, severely weakening the durability and load-bearing capacity of the lining structure.

[0003] To address this issue, blind pipes are often installed between the secondary lining and the initial support in engineering projects. These pipes guide seepage water into the seepage water, which is then discharged into a sump and finally pumped out. To prevent silt from entering with the water flow and clogging the inlet holes of the blind pipes, existing technology involves wrapping the outside of the blind pipes with a filter layer (such as geotextile or graded gravel) to intercept solid particles.

[0004] However, after long-term operation, the fine particles of silt carried by the seepage will gradually deposit, compact, and even clump together on the outside of the filter layer, forming a low-permeability "mud crust" that severely hinders water flow into the blind pipe. This not only reduces the permeability of the filter layer but also leads to a significant decrease in the efficiency of seepage water collection and discharge, weakening the effectiveness of the entire drainage system and thus exacerbating the risk of freeze-thaw damage. Summary of the Invention

[0005] To overcome the drawback that fine particles of silt carried by seepage will gradually deposit, compact, or even clump together on the outside of the filter layer, forming a low-permeability "mud shell" that severely hinders water flow into the blind pipe. This not only reduces the permeability of the filter layer but also significantly decreases the efficiency of seepage water collection and discharge, weakening the effectiveness of the entire drainage system, this invention provides a device for collecting seepage water from the wall of a vertical shaft.

[0006] Technical solution: A device for collecting seepage water from the wall of a vertical shaft, comprising a first pipe and a second pipe connected to the first pipe; the second pipe is made of alloy material; it also includes a third pipe, a filter cylinder, a first ring, a first connecting block, and a drive assembly; several third pipes are slidably connected to the first pipe and are connected to the first pipe; several circular holes are opened on the upper part of each third pipe; a filter cylinder is fixedly connected to the outside of each third pipe; several first rings are sleeved on the outside of each filter cylinder; several first connecting blocks are fixedly connected between each two adjacent first rings; a drive assembly is connected to the first pipe.

[0007] More preferably, the drive assembly includes a wire rope, a cylinder, a connecting block, and a spring; the wire rope is threaded through all the pipes; the cylinder is connected to the pipe; the cylinder is fixedly connected to the pipe; the cylinder passes through the secondary lining; the connecting block is fixedly connected to the cylinder; the two ends of the wire rope pass through the connecting block; and a spring is fixedly connected to each pipe.

[0008] More preferably, the pipe has a groove.

[0009] More preferably, it also includes a second cylinder; a second cylinder is slidably connected to the outside of each third pipe, and the second cylinder is fixedly connected to the corresponding spring; several connecting blocks are also fixedly connected between each second cylinder and the corresponding ring.

[0010] More preferably, the wire rope is made of stainless steel.

[0011] More preferably, it also includes guide wheels; several guide wheels are fixedly connected between pipe one and cylinder one, and the wire rope is in contact with the guide wheels.

[0012] More preferably, it also includes a connecting block three; the two ends of the wire rope are jointly fixed together by the connecting block three.

[0013] More preferably, it also includes a second ring; several second rings are fixed to each third pipe, and the wire rope slides inside the second ring.

[0014] More preferably, the ring has a chamfer.

[0015] More preferably, the inner surface of the second ring is set as a smooth surface.

[0016] Compared with the prior art, the present invention has the following advantages: First, by moving the pipe and filter cylinder through the steel wire rope, the "mud shell" that has hardened on the outside of the filter cylinder is scraped off by the circular ring, so that the filter cylinder can restore its water permeability. This avoids the decrease in the efficiency of seepage water collection and discharge caused by the hardening of mud and sand on the outside of the filter cylinder, thereby reducing the risk of freeze-thaw damage. The multiple circular rings set on the outside of the filter cylinder can block and intercept stones, preventing stones from scratching the filter cylinder and playing a role in protecting the filter cylinder. Second, grooves are made at the three ends of the pipe to drain accumulated water, thus avoiding the problem of poor drainage caused by the inner ends of the three pipes abutting against the inner wall of the first pipe. Third, the sand and gravel are intercepted by the second cylinder to prevent them from flowing and filling the outer end of the third pipe, thus ensuring that the third pipe can be reset normally and avoiding the problem of interfering with subsequent maintenance operations due to reset failure. Fourth, the connection between pipe one and cylinder one is protected by guide rollers, and pipe three is protected by ring two, which helps to reduce wear and improve service life.

Detailed Implementation

[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names, and the disclosure contained throughout the specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, side, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] Example 1: A device for collecting seepage water from the wall of a vertical shaft, such as... Figures 1-6 As shown, it includes pipe 1 and pipe 2; pipe 2 is connected to and fixed to pipe 1, and pipe 2 is made of alloy material; it also includes pipe 3, filter cartridge 4, ring 5, connecting block 206 and drive assembly; ten pipes 3 are slidably connected to pipe 1, and these pipes 3 are all connected to the inside of pipe 1; each pipe 3 has several round holes 91 on its upper part; a filter cartridge 4 is fixed to the outside of each pipe 3; six rings 5 ​​are sleeved on the outside of each filter cartridge 4; two connecting blocks 206 are fixed between each two adjacent rings 5; a drive assembly is connected to pipe 1; the drive assembly is used to drive the pipes 3 to move.

[0021] The drive assembly includes a wire rope 201, a cylinder 202, a connecting block 203, and a spring 204; the wire rope 201 is threaded through all the pipes 3; the cylinder 202 is connected to the pipe 1 and fixed thereto; the cylinder 202 passes through the secondary lining 6; the connecting block 203 is bolted to the cylinder 202; the two ends of the wire rope 201 pass out from the connecting block 203; and a spring 204 is fixed to each pipe 3.

[0022] First, pipe 1 is embedded in the initial support. The initial support secures pipe 1, ring 5, and spring 204, connecting pipe 2 to the sump. During normal use, seepage water from the rock strata flows into the initial support, then through filter cylinder 4 and into the inside of pipe 3 through hole 91. From there, it flows into pipe 1, and then into the sump via pipe 2, completing the seepage water collection process. This significantly reduces seepage water flowing into the secondary lining 6, thereby minimizing freeze-thaw cycles. To mitigate the risk of damage, filter cartridge 4 intercepts sediment in the seepage water, preventing it from clogging the round holes 91. During regular maintenance, workers are transported to the side of connecting block 203 via a suspended platform. The two ends of the wire rope 201 are then manually secured to a portable winch, which is used to wind up the wire rope 201, tightening it to the side of pipe 1 near the secondary lining 6. During this process, the wire rope 201 pulls pipe 3 towards the secondary lining 6. The spring 204 is stretched, and the pipe 3 moves the filter cylinder 4, causing it to slide inside the ring 5. During this process, the moving filter cylinder 4 moves relative to the fixed ring 5, and the edge of the ring 5 scrapes off the "mud shell" that has hardened on the outside of the filter cylinder 4, restoring its water-permeable function. Then, the steel wire rope 201 is unwound manually using a portable winch. At this time, the spring 204 rebounds, causing the pipe 3 to move back to its original position. The pipe 3 then pulls the steel wire rope 201 back to its original position, completing the process. Maintenance operation; during use, the steel wire rope 201 drives the pipe 3 and filter cylinder 4 to move, thereby scraping off the "mud shell" that has hardened on the outside of the filter cylinder 4 through the ring 5, so that the filter cylinder 4 can restore its water permeability. This avoids the problem of reduced efficiency in seepage water collection and discharge caused by mud and sand hardening on the outside of the filter cylinder 4, thereby reducing the risk of freeze-thaw damage. The multiple rings 5 ​​set on the outside of the filter cylinder 4 can block and intercept stones, preventing stones from scratching the filter cylinder 4, thus achieving the effect of protecting the filter cylinder 4.

[0023] The pipe 3 has a groove 92. When the end of the pipe 3 is against the inside of the pipe 1, the liquid in the pipe 3 can be discharged from the groove 92.

[0024] by Figure 3For example, when the wire rope 201 drives the pipe 3 to move towards the secondary lining 6, the inner end of the pipe 3 will abut against the inner wall of the pipe 1, which will cause the pipe 3 to have poor drainage at this time. At this time, in the initial stage of cleaning the "mud shell" on the outside of the filter cartridge 4, a large amount of water will flow into the pipe 3. In order to meet the drainage needs, a groove 92 is opened at the end of the pipe 3. Even if the inner end of the pipe 3 abuts against the inner wall of the pipe 1, the water in the pipe 3 can be discharged from the groove 92. In use, the groove 92 is opened at the end of the pipe 3, and the water is discharged through the groove 92, avoiding the problem of poor drainage caused by the inner end of the pipe 3 abutting against the inner wall of the pipe 1.

[0025] It also includes a second cylinder 205; a second cylinder 205 is slidably connected to the outside of each third pipe 3, the second cylinder 205 is fixedly connected to the corresponding spring 204, and the second cylinder 205 is made of alloy material; two connecting blocks 206 are also fixedly connected between each second cylinder 205 and the corresponding ring 5.

[0026] by Figure 3 For example, after the wire rope 201 moves the pipe 3, the gravel will flow and fill the outer end of the pipe 3. This causes the gravel to block the movement of the pipe 3 when the spring 204 moves the pipe 3 back to its original position, resulting in the failure of the pipe 3 to reset. This interferes with subsequent maintenance operations. Therefore, a cylinder 205 is installed at the outer end of the pipe 3. The cylinder 205 is fixed to the initial support, and the spring 204 is fixed inside the cylinder 205. The wire rope 201 moves the pipe 3... When in motion, the outer end of pipe 3 slides inside cylinder 205 and will not slide out from inside cylinder 205. At this time, the sand and gravel are intercepted by cylinder 205 to prevent them from flowing and filling to the outer end of pipe 3. When resetting, spring 204 rebounds and can drive pipe 3 back to its original position. When in use, the sand and gravel are intercepted by cylinder 205 to prevent them from flowing and filling to the outer end of pipe 3 and interfering with its resetting, thus avoiding the problem of interfering with subsequent maintenance operations due to resetting failure.

[0027] The 201 steel wire rope is made of stainless steel to prevent it from getting stuck or hindering the pulling operation due to rust.

[0028] Example 2, based on Example 1, such as Figures 3-6 As shown, it also includes guide wheels 207; two guide wheels 207 are fixedly connected between pipe 1 and cylinder 202, and the wire rope 201 is in contact with the guide wheels 207.

[0029] It also includes a connecting block 3 208; the two ends of the wire rope 201 are fixed together by the connecting block 3 208. The connecting block 3 208 is manually fixed to the portable winch, and the portable winch directly raises and lowers the connecting block 3 208, thereby synchronously driving the two ends of the wire rope 201.

[0030] It also includes a second ring 209; two rings 209 are fixed to each pipe 3, and the wire rope 201 slides inside the ring 209 to prevent the wire rope 201 from wearing down the pipe 3.

[0031] The ring 5 has a chamfer, which helps to improve the removal of impurities.

[0032] The inner surface of ring 209 is set as a smooth surface to reduce friction.

[0033] The connecting block 3 208 is manually fixed to the portable winch, and the portable winch directly raises and lowers the connecting block 3 208, thereby synchronously driving the two ends of the wire rope 201. There is no need to fix the two ends of the wire rope 201 to the portable winch one by one, which helps to improve the convenience of operation.

[0034] When the portable winch tightens the wire rope 201, the wire rope 201 moves on the guide wheel 207, thereby preventing the wire rope 201 from wearing down the connection between the pipe-1 and the cylinder-202, which helps to improve the service life.

[0035] When the portable winch tightens the wire rope 201, the wire rope 201 slides inside the second ring 209, and the second ring 209 protects the third pipe 3, preventing the wire rope 201 from wearing down the third pipe 3.
