Technical Field

[0001] This disclosure relates to the field of waterproofing technology for underground utility tunnels, and in particular to a waterproofing device for wall penetration holes in underground utility tunnels and a leakage monitoring system. Background Technology

[0002] Underground utility tunnels are tunnel spaces built underground in cities, integrating various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. Underground utility tunnels typically house high-voltage power lines, gas pipelines, water supply pipelines, drainage pipelines, and communication cables, and have high requirements for waterproofing.

[0061] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0062] In order to solve the problems mentioned in the background art, the present invention provides the following embodiments.

[0063] Example 1

[0064] Please refer to Figures 1 to 8This embodiment proposes a waterproofing device for underground utility tunnel wall penetrations, comprising a utility tunnel sidewall 1 coated with a waterproof layer on both its inner and outer sides, and a through hole 11 for water pipes, cables, or gas pipelines to pass through. Specifically, the inner and outer sides of the utility tunnel sidewall 1 are coated with a waterproof layer, and the inner wall of the through hole 11 is also coated with a waterproof layer. To achieve a better waterproofing effect, an annular sealing groove is provided on the utility tunnel sidewall 1 in practical applications. The device also includes a first sealing pipe 2, a second sealing pipe 3, a sealing assembly 4, and an outer tightening ring 5.

[0065] Specifically, one end of the first sealing tube 2 is provided with a first retaining ring 21, the outer diameter of which is larger than the outer diameter of the annular sealing groove. The first sealing tube 2 is inserted into the through hole 11 from the outside of the side wall 1 of the pipe gallery, and the first retaining ring 21 abuts against the outside of the side wall 1 of the pipe gallery.

[0066] One end of the second sealing tube 3 is provided with a second retaining ring 31. The second sealing tube 3 is inserted into the through hole 11 from the inside of the pipe gallery side wall 1 and is threadedly connected to the first retaining ring 21. The second retaining ring 31 abuts against the inside of the pipe gallery side wall 1. In specific implementation, the outer diameter of the second retaining ring 31 is larger than the outer diameter of the annular sealing groove. By controlling the threaded connection length between the second sealing tube 3 and the first sealing tube 2, the tightness between the first retaining ring 21 and the second retaining ring 31 and the pipe gallery side wall 1 can be adjusted to ensure the sealing between the first retaining ring 21, the second retaining ring 31 and the pipe gallery side wall 1.

[0067] The outer circumference of the sealing component 4 is conical. That is, the outer diameter of the sealing component 4 gradually increases or decreases from one end to the other. The inner diameter of the sealing component 4 is approximately equal to the outer diameter of the water pipe, cable, or gas pipe to be installed. The sealing component 4 is fitted onto the water pipe, cable, or gas pipe passing through the through hole 11, with the larger diameter end of the sealing component 4 abutting against the first retaining ring 21. The outer tightening ring 5 is fitted onto the water pipe, cable, or gas pipe passing through the through hole 11, with one end threadedly connected to the first retaining ring 21; the inner diameter of the outer tightening ring 5 is conical, and the cone apex angle corresponding to the inner diameter is smaller than the cone apex angle corresponding to the outer circumference of the sealing component 4. In practical implementation, the inner diameter of the smaller end of the tapered hole of the outer tightening ring 5 should be larger than the outer diameter of the smaller end of the sealing component 4, but smaller than the outer diameter of the larger end of the sealing component. During installation, when the outer tightening ring 5 and the first retaining ring 21 are tightened, the pressure on the sealing component 4 has a radially inward component, pressing the sealing component 4 between the outer tightening ring 5 and the water pipe, cable, or gas pipeline. This achieves a seal between the first sealing pipe 2 and the water pipe, cable, or gas pipeline. In practical implementation, the inner diameter of the smaller end of the outer tightening ring 5 can be set to be 1 to 2 centimeters larger than the outer diameter of the water pipe, cable, or gas pipeline to be installed.

[0068] In practical implementation, since the inner diameter of the sealing component 4 is roughly the same as the outer diameter of the water pipe, cable, or gas pipeline to be installed, it is not easy to fit the sealing component 4 onto the outer diameter of the water pipe, cable, or gas pipeline during installation. Furthermore, directly fabricating a split structure can easily lead to tiny gaps at the joints, causing external water to seep in. To solve this problem, this embodiment further designs the sealing component 4. Specifically, the sealing component 4 includes a first sealing element 41 and a second sealing element 42.

[0069] Please refer to Figures 4 to 6 Both the first sealing element 41 and the second sealing element 42 are semi-annular structures. In some implementations, the curvatures of the first sealing element 41 and the second sealing element 42 may be unequal, as long as the first sealing element 41 and the second sealing element 42 can form an annular sealing assembly 4 as described above. Specifically, the first sealing element 41 has a first protrusion 411 extending in the circumferential direction at its first end and a first recess 412 recessed in the circumferential direction at its second end; the first protrusion 411 extends along the axial direction of the first sealing element 41; the second sealing element 42 has a second recess 421 that mates with the first protrusion 411 at one end and a second protrusion 422 that mates with the first recess 412 at the second end; the first sealing element 41 and the second sealing element 42 cooperate to form an annular structure. When the first seal 41 and the second seal 42 are engaged, the position where the first seal 41 and the second seal 42 are in contact forms a contact surface around the center line of the sealing assembly 4. Since the outer tightening ring 5 exerts radial inward pressure on the sealing assembly 4, a tight seal can be formed at the joint between the first seal 41 and the second seal 42.

[0070] During installation, after fixing the first seal 41 and the second seal 42 to the installation location, tighten the outer tightening ring 5. During this process, it is necessary to maintain the relative position of the first seal 41 and the second seal 42. Since both the first seal 41 and the second seal 42 are located inside the outer tightening ring 5, it is not easy to maintain their relative positions. Therefore, this embodiment has made further improvements. Specifically, a limiting groove 413 is provided on the side where the first protrusion 411 mates with the second recess 421; a limiting block 423 is provided on the side where the second recess 421 mates with the first protrusion 411. Through the cooperation of the limiting groove 413 and the limiting block 423, relative axial movement between the first seal 41 and the second seal 42 can be prevented.

[0071] The limiting groove 413 extends circumferentially along the first seal 41, forming a positioning hole 414 at the first end of the first seal 41; the limiting block 423 extends circumferentially along the second seal 42, forming a positioning pin 424 at the second end of the second seal 42; the positioning pin 424 is adapted to the positioning hole 414. By setting the positioning pin 424 and the positioning hole 414, the first seal 41 and the second seal 42 can be pre-installed. Through the friction between the positioning pin 424 and the positioning hole 414, the first seal 41 and the second seal 42 are prevented from separating after they are engaged and before the outer tightening ring 5 is tightened.

[0072] To facilitate processing and manufacturing and minimize the number of molds required, in specific implementations, the first sealing element 41 and the second sealing element 42 have the same shape and size. That is, the first sealing element 41 and the second sealing element 42 are of the same type, and two first sealing elements 41 can be fitted together to form the aforementioned sealing assembly 4. In some implementations, a C-shaped metal skeleton can be provided inside the first sealing element 41, with wedge-shaped end faces to prevent the sealing assembly 4 from being too soft and resulting in a loose seal.

[0073] In practical implementation, to prevent water from seeping into the pipe rack through the gap between the outer tightening ring 5 and the first retaining ring 21, the side of the first retaining ring 21 facing away from the pipe rack sidewall 1 is provided with an external threaded connector 22, which is threadedly connected to the outer tightening ring 5. The side of the first retaining ring 21 facing away from the pipe rack sidewall 1 is also provided with a first annular groove 23, within which a first sealing gasket 24 is provided. The first retaining ring 21 extends into the first annular groove 23 and presses against the first sealing gasket 24. That is, when one end of the outer tightening ring 5 is inserted into the first annular groove 23, the sealing between the outer tightening ring 5 and the first annular groove 23 is achieved by compressing the first sealing gasket 24, due to the presence of the first sealing gasket 24 within the first annular groove 23. Furthermore, the first annular groove 23 creates multiple folds at the gap, increasing the difficulty of water seepage.

[0074] In practical implementation, to improve the seal between the first sealing pipe 2, the second sealing pipe 3, and the pipe rack sidewall 1, this embodiment has been further designed. Specifically, the first sealing pipe 2 is sleeved on the second sealing pipe 3. The outer surface of the first sealing pipe 2 is provided with a tapered portion 25, with the smaller diameter end of the tapered portion 25 located on the side of the first retaining ring 21 near the pipe rack sidewall 1. By providing the tapered portion 25, it is easier to form a seal between the pipe rack sidewall 1 and the first sealing pipe 2.

[0075] A second sealing gasket 26 is fitted onto the first sealing tube 2. The second sealing gasket 26 is fitted onto the first sealing tube 2 and is located at the conical part 25. The inner hole of the second sealing gasket 26 is a conical hole and is adapted to the conical part 25.

[0076] The second sealing gasket 26 extends radially outward from the end near the first retaining ring 21 to form a first sealing ring 261, which is located between the first retaining ring 21 and the pipe rack sidewall 1. The outer diameter of the first sealing ring 261 is larger than the outer diameter of the annular sealing groove on the pipe rack sidewall 1. When the first sealing tube 2 and the second sealing tube 3 are tightened, the first retaining ring 21 presses against the first sealing ring 261, causing the first sealing ring 261 to deform and fill the annular sealing groove on the pipe rack sidewall 1, thereby achieving a seal. Correspondingly, the first retaining ring 21 has at least two second annular grooves 211 on the side near the second sealing gasket 26. When the first sealing tube 2 and the second sealing tube 3 are tightened, the second sealing gasket 26 is deformed under pressure and fills into the second annular grooves 211. The tapered portion 25 has at least two third annular grooves 251. In practice, the second sealing gasket 26 can be water-swellable rubber. When the second sealing gasket 26 expands when it comes into contact with water, it can fill the third annular groove 251 to reduce the stress caused by the expansion of the rubber.

[0077] In specific implementation, to further prevent water from seeping into the pipe gallery from between the second sealing pipe 3 and the pipe gallery sidewall 1, this embodiment also includes a third sealing gasket 6, which is fitted onto the second sealing pipe 3. In specific implementation, since the second sealing pipe 3 is fitted onto the first sealing pipe 1, a space exists on the first sealing pipe 1 when the two are connected. The third sealing gasket 6 fills this space. The end of the third sealing gasket 6 near the second retaining ring 31 extends radially outward to form a second sealing ring 61, located between the second retaining ring 31 and the pipe gallery sidewall 1. The outer diameter of the second sealing ring 61 is larger than the annular sealing groove on the pipe gallery sidewall 1. The second retaining ring 31 near the third sealing gasket 6 has a fourth annular groove 311, and the second sealing pipe 3 near the outer periphery of the second retaining ring 31 has a fifth annular groove 32. When the first sealing pipe 2 and the second sealing pipe 3 are tightened, the third sealing gasket 6 deforms under pressure, filling the fourth annular groove 311 and the fifth annular groove 32. To improve the sealing effect. In specific implementation, to adapt to different needs, sealing rings can be added or removed from the first sealing tube 1 to ensure that the space is completely filled.

[0078] The above structure enables sealing between the first sealing pipe 2, the second sealing pipe 3, and the side wall 1 of the pipe gallery, as well as sealing between the first sealing pipe 2 and the water pipe, cable, or gas pipeline to be installed. However, the sealing between the first sealing pipe 2 and the water pipe, cable, or gas pipeline is only achieved by the sealing component 4, which is relatively weak. Therefore, this embodiment has been further designed, specifically including a third sealing element 7 and a top ring 8. The third sealing element 7 is spiral-shaped and located inside the second sealing pipe 3, spirally coiled around the water pipe, cable, or gas pipeline, with one end abutting against the sealing component 4. Since the inner diameter of the third sealing element 7 is similar to the outer diameter of the water pipe, cable, or gas pipeline, it is inconvenient to directly sleeve the third sealing element 7 onto the water pipe, cable, or gas pipeline. By setting the third sealing element 7 as a spiral structure, the problem of inconvenient installation of the third sealing element 7 can be effectively solved. The top ring 8 is threadedly connected to the second sealing pipe 3, and the top ring 8 abuts against the side of the third sealing element 7 away from the sealing component 4. The function of the top ring 8 is to press the third sealing element 7 against the wall, so that the third sealing element 7 deforms and fills the space between the water pipe, cable or gas pipe and the first sealing pipe 2, and between the water pipe, cable or gas pipe and the second sealing pipe 3.

[0079] In some implementations, for ease of installation, the second retaining ring 31 has a hexagonal tube on the side facing away from the pipe rack sidewall 1, facilitating installation and disassembly. Correspondingly, the top ring 8 also has a hexagonal tube on the side facing into the pipe rack. The side of the top ring 8 near the third seal 7 is curved to avoid damage to the third seal 7 during compression. In practical applications, the portion of the second sealing tube 3 that does not extend into the end of the first sealing tube 2 forms an unfilled space. The third seal 7 is deformed by the compression of the top ring 8, thus filling this unfilled space. In specific implementations, the third seal 7 can be made of water-swellable rubber.

[0080] Example 2

[0081] This embodiment is a further improvement based on Embodiment 1. The similarities will not be repeated. Only the differences will be explained below.

[0082] This embodiment proposes a leakage monitoring system, which includes multiple waterproofing devices for underground utility tunnel through-wall holes as described in Embodiment 1; it also includes a first humidity sensor disposed on the side of the first retaining ring 21 away from the sidewall 1 of the utility tunnel; a second humidity sensor disposed on the side of the second retaining ring 31 away from the sidewall 1 of the utility tunnel; a first pressure sensor disposed within the sealing assembly 4; a second pressure sensor disposed on the first retaining ring 21 near the sidewall 1 of the utility tunnel; and a controller, which is communicatively connected to the first humidity sensor, the second humidity sensor, the first pressure sensor, and the second pressure sensor; the controller is used to acquire the detection results of the first humidity sensor, the second humidity sensor, the first pressure sensor, and the second pressure sensor to determine the leakage status and aging status of the waterproofing devices for underground utility tunnel through-wall holes.

[0083] The first humidity sensor is used to detect the air humidity at one end of the waterproof device located inside the pipe gallery, and the second humidity sensor is used to detect the soil humidity at one end of the waterproof device located outside the pipe gallery; the first pressure sensor is used to detect the force inside the sealing assembly 4, and the second pressure sensor is used to detect the pressure on the second sealing gasket 26.

[0084] The controller has pre-stored the numbering information of each first humidity sensor, second humidity sensor, first pressure sensor and second pressure sensor. First humidity sensors, second humidity sensors, first pressure sensors and second pressure sensors with the same numbering information are located at the same through hole 11.

[0085] For the first humidity sensor, second humidity sensor, first pressure sensor, and second pressure sensor with the same numbering information, the controller acquires the detection results of the first humidity sensor, second humidity sensor, first pressure sensor, and second pressure sensor in real time.

[0086] The first humidity sensor is compared with a preset first humidity value. When the detection result of the first humidity sensor is greater than the set humidity value, the controller sends an alarm signal and corresponding number information to the remote control center with which it is connected.

[0087] The controller is also used to compare the detection result of the second humidity sensor with the preset second humidity value, and calculate the first warning index when the detection result of the second humidity sensor is greater than the second humidity value;

[0088]

[0089] Where c represents the first warning index; The results are from the first humidity sensor. The result is the detection result of the second humidity sensor; when the first warning index is less than 30%, the controller sends a warning signal and the corresponding number information to the remote control center with which it is connected.

[0090] The controller is also used to acquire the detection results of the first and second pressure sensors in real time, and to determine whether the detection results of the first and second pressure sensors have abruptly changed. When the detection results of the first and / or second pressure sensors abruptly change, the controller sends an early warning signal and corresponding number information to the remote control center with which it is communicatively connected. A sudden change in the detection results of the first and / or second pressure sensors refers to a decrease in the detection results of the first and / or second pressure sensors exceeding 10% within a set time period. For example, the detection result of the first or second pressure sensor decreases by 10% within 10 minutes. The controller is also used to compare the detection results of the first and second pressure sensors with the corresponding first and second pressure values, respectively. When the detection result of the first pressure sensor is less than the first pressure value or the detection result of the second pressure sensor is less than the second pressure value, the controller sends an early warning signal and corresponding number information to the remote control center with which it is communicatively connected.
