[0002] An underground utility tunnel is a tunnel space built underground in a city, integrating various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage. Underground utility tunnels usually have high-voltage wires, gas pipelines, water supply pipelines, drainage pipelines, communication cables, etc., and have relatively high requirements for waterproofing.

[0061] In order to make the objectives, technical solutions, and advantages of the present disclosure more apparent, the exemplary embodiments according to the present disclosure will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. It should be understood that the present disclosure is not limited by the exemplary embodiments described herein.

[0062] To solve the problems raised in the background art, the present invention proposes the following embodiments.

[0063] Embodiment 1

[0064] Please refer to Figures 1 to 8, this embodiment proposes a waterproof device for the wall-piercing holes of an underground utility tunnel, which includes a tunnel sidewall 1 coated with waterproof layers on both the inner and outer sides. The tunnel sidewall 1 is also provided with a through-hole 11 for water pipes, cables or gas pipes to pass through. Specifically, waterproof layers are provided on both the inner and outer sides of the tunnel sidewall 1, and the inner wall of the through-hole 11 is also coated with a waterproof layer. In order to achieve a better waterproof effect, in practical applications, an annular sealing groove is provided on the tunnel sidewall 1. Among them, it also includes a first sealing pipe 2, a second sealing pipe 3, a sealing component 4 and an outer tightening ring 5.

[0065] Specifically, one end of the first sealing pipe 2 is provided with a first retaining ring 21, and the outer diameter of the first retaining ring 21 is greater than the outer diameter of the annular sealing groove. The first sealing pipe 2 is inserted into the through-hole 11 from the outside of the tunnel sidewall 1, and the first retaining ring 21 abuts against the outside of the tunnel sidewall 1.

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

[0067] The outer periphery of the sealing component 4 is conical. That is, along the direction from one end to the other end of the outer periphery of the sealing component 4, the outer diameter of the sealing component 4 gradually increases or gradually decreases. The inner hole of the sealing component 4 is equivalent to the outer diameter of the water pipe, cable or gas pipe to be installed. The sealing component 4 is sleeved on the water pipe, cable or gas pipe passing through the through-hole 11, and the larger-diameter end of the sealing component 4 abuts against the first retaining ring 21. The outer tightening ring 5 is sleeved on the water pipe, cable or gas pipe passing through the through-hole 11, and one end is threadedly connected to the first retaining ring 21; the inner hole of the outer tightening ring 5 is conical, and the cone apex angle corresponding to the inner hole is smaller than the cone apex angle corresponding to the outer periphery of the sealing component 4. In specific implementation, the inner diameter of the smaller end of the conical hole of the outer tightening ring 5 should be greater than the outer diameter of the smaller end of the sealing component 4 and less than the outer diameter of the larger end of the sealing component 4. During installation, when the outer tightening ring 5 is tightened with the first retaining ring 21, the pressure received by the sealing component 4 has a radially inward component force, so that the sealing component 4 is pressed tightly between the outer tightening ring 5 and the water pipe, cable or gas pipe. Thus, the sealing between the first sealing pipe 2 and the water pipe, cable or gas pipe is achieved. In specific implementation, the inner diameter of the smaller end of the inner diameter 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 pipe to be installed.

[0068] In specific implementation, since the inner diameter of the sealing component 4 is comparable to the outer diameter of the water pipe, cable or gas pipeline to be installed, when installing the sealing component 4, it is not easy to sleeved the sealing component 4 onto the outer diameter of the water pipe, cable or gas pipeline to be installed. And directly making it into a split structure is likely to cause tiny gaps at the joints, resulting in the infiltration of external water. To solve this problem, in this embodiment, the sealing component 4 is further designed. Specifically, the sealing component 4 includes a first sealing member 41 and a second sealing member 42.

[0069] Please refer to Figures 4 to 6 , both the first sealing member 41 and the second sealing member 42 are semi-circular structures; in some implementation manners, the corresponding arcs of the first sealing member 41 and the second sealing member 42 can be unequal, as long as the first sealing member 41 and the second sealing member 42 can form the annular sealing component 4 as described above. Specifically, the first end of the first sealing member 41 is provided with a first protruding portion 411 extending in the circumferential direction, and the second end is provided with a first recessed portion 412 recessed in the circumferential direction; the first protruding portion 411 extends along the axis direction of the first sealing member 41; one end of the second sealing member 42 is provided with a second recessed portion 421 cooperating with the first protruding portion 411, and the second end is provided with a second protruding portion 422 cooperating with the first recessed portion 412; the first sealing member 41 and the second sealing member 42 cooperate to form an annular structure. When the first sealing member 41 and the second sealing member cooperate, the position where the first sealing member 41 and the second sealing member 42 are in contact forms a contact surface around the center line of the sealing component 4. Since the outer tightening ring 5 has a radially inward pressure on the sealing component 4, therefore, a tight seal can be formed at the joint of the first sealing member 41 and the second sealing member 42.

[0070] During specific installation, after fixing the first sealing member 41 and the second sealing member 42 at the installation position, tighten the outer tightening ring 5. During this process, it is necessary to keep the relative positions of the first sealing member 41 and the second sealing member 42 unchanged. Since both the first sealing member 41 and the second sealing member 42 are inside the outer tightening ring 5, it is not easy to keep the relative positions of the first sealing member 41 and the second sealing member 42 unchanged. For this reason, this embodiment is further improved. Specifically, a limiting groove 413 is provided on the side where the first protruding portion 411 cooperates with the second recessed portion 421; a limiting block 423 is provided on the side where the second recessed portion 421 cooperates with the first protruding portion 411; through the cooperation of the limiting groove 413 and the limiting block 423, the relative axial movement between the first sealing member 41 and the second sealing member 42 can be prevented.

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

[0072] For the convenience of processing and manufacturing and to minimize the number of mold openings as much as possible, in specific implementation, the first seal 41 and the second seal 42 have the same shape and size. That is, the first seal 41 and the second seal 42 are parts of the same model, and two first seals 41 can be fitted to form a seal assembly 4 as described above. In some implementation manners, a C-shaped metal skeleton can be provided inside the first seal 41, and the end face of the C-shaped metal skeleton is wedge-shaped to prevent the seal assembly 4 from being too soft and resulting in loose sealing.

[0073] In specific implementation, to prevent water from seeping into the pipe gallery interior between the outer tightening ring 5 and the first retaining ring 21, an external thread joint 22 is provided on the side of the first retaining ring 21 facing away from the pipe gallery side wall 1, and the external thread joint 22 is threadedly connected to the outer tightening ring 5. A first annular groove 23 is also provided on the side of the first retaining ring 21 facing away from the pipe gallery side wall 1, and a first gasket 24 is provided in the first annular groove 23. The first retaining ring 21 extends into the first annular groove 23 and abuts against the first gasket 24. That is, one end of the outer tightening ring 5 is inserted into the first annular groove 23. Since the first gasket 24 is provided in the first annular groove 23, the seal between the outer tightening ring 5 and the first annular groove 23 can be achieved by squeezing the first gasket 24. At the same time, by providing the first annular groove 23, multiple folding surfaces can be formed at the gap, increasing the difficulty of water seepage.

[0074] In specific implementation, to improve the seal between the first seal pipe 2, the second seal pipe 3 and the pipe gallery side wall 1, further design is made in this embodiment. Specifically, the first seal pipe 2 is sleeved on the second seal pipe 3. A tapered portion 25 is provided on the outer surface of the first seal pipe 2, and the end with a smaller diameter of the tapered portion 25 is located on the side of the first retaining ring 21 close to the pipe gallery side wall 1. By providing the tapered portion 25, it is convenient to form a seal between the pipe gallery side wall 1 and the first seal pipe 2.

[0075] A second gasket 26 is sleeved on the first seal pipe 2. The second gasket 26 is sleeved on the first seal pipe 2 and is located at the tapered portion 25; the inner hole of the second gasket 26 is a tapered hole and is adapted to the tapered portion 25.

[0076] One end of the second gasket 26 close to the first retaining ring 21 extends radially outward to form a first sealing ring 261. The first sealing ring 261 is located between the first retaining ring 21 and the side wall 1 of the pipe gallery. The outer diameter of the first sealing ring 261 is greater than the outer diameter of the annular sealing groove on the side wall 1 of the pipe gallery. When the first sealing pipe 2 and the second sealing pipe 3 are tightened, the first retaining ring 21 presses the first sealing ring 261, causing the first sealing ring 261 to deform and fill the annular sealing groove on the side wall 1 of the pipe gallery to achieve sealing. Correspondingly, at least two second annular grooves 211 are provided on one side of the first retaining ring 21 close to the second gasket 26; when the first sealing pipe 2 and the second sealing pipe 3 are tightened, the second gasket 26 is compressed and deformed and fills into the second annular grooves 211. At least two third annular grooves 251 are provided on the tapered portion 25. In a specific implementation, the second gasket 26 can be a water-swellable rubber. When the second gasket 26 swells in water, it can fill into the third annular grooves 251 to reduce the stress caused by the swelling of the rubber.

[0077] In a specific implementation, to further prevent water from seeping into the pipe gallery between the second sealing pipe 3 and the side wall 1 of the pipe gallery, the present embodiment further makes a further setting, which further includes a third gasket 6 sleeved on the second sealing pipe 3. In a specific implementation, since the second sealing pipe 3 is sleeved on the first sealing pipe 1, when the two are connected, there will be a section of space on the first sealing pipe 1. By providing the third gasket 6, the section of space is filled by the third gasket 6. One end of the third gasket 6 close to the second retaining ring 31 extends radially outward to form a second sealing ring 61. The second sealing ring 61 is located between the second retaining ring 31 and the side wall 1 of the pipe gallery. The outer diameter of the second sealing ring 61 is greater than the annular sealing groove on the side wall 1 of the pipe gallery. A fourth annular groove 311 is provided on one side of the second retaining ring 31 close to the third gasket 6, and a fifth annular groove 32 is provided on the outer periphery of the second sealing pipe 3 close to the second retaining ring 31. When the first sealing pipe 2 and the second sealing pipe 3 are tightened, the third gasket 6 is compressed and deformed and fills into the fourth annular groove 311 and the fifth annular groove 32 to improve the sealing effect. In a specific implementation, for the convenience of adapting to different needs, sealing rings can also be added or reduced on the first sealing pipe 1 so that the section of space is completely filled.

[0078] With the above structure, the sealing between the first sealing pipe 2, the second sealing pipe 3 and the side wall 1 of the pipe gallery can be achieved, as well as the 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 to be installed is only achieved by the sealing component 4, and the sealing at this place is still relatively weak. Therefore, this embodiment is further designed. Specifically, it further includes a third sealing member 7 and a top ring 8. The third sealing member 7 is spiral. The third sealing member 7 is located inside the second sealing pipe 3 and spirally wound around the water pipe, cable or gas pipeline, and one end of it abuts against the sealing component 4. Since the inner diameter of the third sealing member 7 is equivalent to the outer diameter of the water pipe, cable or gas pipeline, it is inconvenient to operate if the third sealing member 7 is directly sleeved on the water pipe, cable or gas pipeline. By setting the third sealing member 7 as a spiral structure, the problem of inconvenient installation of the third sealing member 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 member 7 away from the sealing component 4. The function of the top ring 8 is to press the third sealing member 7 tightly, so that the third sealing member 7 deforms and fills the space between the water pipe, cable or gas pipeline and the first sealing pipe 2, and the space between the water pipe, cable or gas pipeline and the second sealing pipe 3.

[0079] In some implementation manners, for the convenience of installation, a pipe with a hexagonal cross-sectional profile is provided on the side of the second retaining ring 31 facing away from the side wall 1 of the pipe gallery, so as to facilitate installation and disassembly. Correspondingly, a pipe with a hexagonal cross-section is also provided on the side of the top ring 8 facing the inside of the pipe gallery. The side of the top ring 8 close to the third sealing member 7 is an arc surface to avoid damage to the third sealing member 7 during the extrusion process. In practical applications, the part of the second sealing pipe 3 that does not extend into the end of the first sealing pipe 2 forms an unfilled space. By pressing the third sealing member 7 with the top ring 8, the third sealing member 7 deforms, so as to fill this unfilled space. In specific implementation, the third sealing member 7 can be made of water-swellable rubber.

[0080] Embodiment 2

[0081] This embodiment is a further improvement based on Embodiment 1. The same parts will not be described in detail below, and only the differences will be described.

[0082] The present embodiment proposes a leakage monitoring system, which includes a plurality of underground tunnel wall hole waterproofing devices as described in Example 1; and also includes a first humidity sensor arranged on the side of the first retaining ring 21 away from the tunnel side wall 1; a second humidity sensor arranged on the side of the second retaining ring 31 away from the tunnel side wall 1; a first pressure sensor arranged in the sealing assembly 4; a second pressure sensor arranged on the first retaining ring 21 close to the tunnel side wall 1; and a controller, the controller being communicatively connected with the first humidity sensor, the second humidity sensor, the first pressure sensor and the second pressure sensor; the controller is used to obtain the detection results of the first humidity sensor, the second humidity sensor, the first pressure sensor and the second pressure sensor, and judge the leakage state and aging state of the underground tunnel wall hole waterproofing device.

[0083] The first humidity sensor is used to detect the air humidity at one end of the waterproof device located in 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 in the sealing assembly 4, and the second pressure sensor is used to detect the pressure exerted on the second sealing pad 26.

[0084] The controller pre-stores serial number information of each first humidity sensor, second humidity sensor, first pressure sensor and second pressure sensor. The first humidity sensor, second humidity sensor, first pressure sensor and second pressure sensor with the same serial number information are located at the same through hole 11 .

[0085] For the first humidity sensor, the second humidity sensor, the first pressure sensor, and the second pressure sensor having the same number information, the controller obtains the detection results of the first humidity sensor, the second humidity sensor, the first pressure sensor, and the 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 a remote control center connected to the controller.

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

[0088]

[0089] Among them, c is the first warning index; is the detection result of the first humidity sensor, 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 corresponding number information to the remote control center connected to it.

[0090] The controller is also used to obtain the detection results of the first pressure sensor and the second pressure sensor in real time, and determine whether the detection results of the first pressure sensor and the second pressure sensor have mutated. When the detection results of the first pressure sensor and / or the second pressure sensor have mutated, the controller sends a warning signal and the corresponding serial number information to the remote control center communicatively connected thereto. Wherein, the detection results of the first pressure sensor and / or the second pressure sensor mutating means that the detection results of the first pressure sensor and / or the second pressure sensor have a decline amplitude greater than 10% within a set time. For example, within 10 minutes, the detection result of the first pressure sensor or the detection result of the second pressure sensor declines by 10%. The controller is also used to compare the detection results of the first pressure sensor and the second pressure sensor with the corresponding first pressure value and the second pressure 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 a warning signal and the corresponding serial number information to the remote control center communicatively connected thereto.
