Description

Technical Field

[0001] The present invention relates to the technical field of water plugging construction, and in particular to a water plugging construction device for deep-buried underground tunnels that can be quickly disassembled and assembled. Background Art

[0002] At present, the underground tunnel project is developing rapidly. During the construction in the water-rich underground area, poor hydrogeological conditions such as water seepage, dripping water, and water gushing are often encountered. Large water gushing in the hole is often encountered, and the excavation has to be stopped for water plugging construction.

[0003] At present, when construction workers carry out water plugging construction operations, due to the diameter and area of the tunnel, it is necessary for the operators to set up a support, and then they can carry out water plugging construction operations. This greatly reduces the water plugging efficiency of the construction workers; moreover, during the process of setting up the support, due to the reasons of the tunnel support and the internal space, the construction time is relatively long. Secondly, due to the long time for setting up the support, the water plugging construction operations cannot be carried out efficiently and quickly; in addition, after the operation is completed, due to the width and height of the tunnel interior, when the operators disassemble the set-up support, it will take a lot of time to complete the disassembly operation. Moreover, since the support needs to be disassembled from high to low, it will require multiple people to cooperate to complete the operation. In order to speed up the disassembly and assembly efficiency, multiple workers need to be equipped to complete the disassembly operation. This method not only increases the personnel cost, but also, due to the increase in personnel, it is difficult to avoid interference, and thus it is easy to cause dangerous situations during the operation process.

[0004] Therefore, in order to improve the operation efficiency of the water plugging construction operation and the disassembly and assembly efficiency, we specifically propose a water plugging construction device for deep-buried underground tunnels that can be quickly disassembled and assembled.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the main frame and the sliding rods on the left and right sides are combined into a certain length in the present invention, under the action of the brushless motor hub, the main frame and the sliding rods are moved to a suitable height. Then, the first motor is started. Under the action of the first motor, the first connecting rod and the second connecting rod drive the water blocking air cushion to closely fit the leaking place of the tunnel main body. Moreover, as the first motor continues to operate, the water blocking air cushion can be more closely attached to the leaking place of the tunnel main body, thereby completing the water blocking operation on the leaking place, facilitating the next operation of the operators; with the cooperation of the above structure, the water blocking construction operation can be efficiently completed, saving the time for the operators to set up the support; secondly, during the disassembly process of the device, only after separating the first friction block and the second friction block from the inner wall of the tunnel main body, start the brushless motor hub to drive the main frame and the sliding rods to move downward as a whole, so that the water blocking air cushion and the inner wall of the tunnel main body are in a separated state. And after the whole device moves to a suitable height, two operators can cooperate to take out the whole device from the inside of the tunnel main body, without occupying the space inside the tunnel main body, avoiding collisions, and ensuring the safety of personnel; furthermore, when carrying out the water blocking operation on the side wall of the tunnel main body, only by separating the first friction blocks at the upper and lower positions of the main frame from the top and bottom of the tunnel main body can the disassembly and assembly operation be completed, saving the disassembly time.

[0017] 2. During the operation of the present invention, the first friction blocks on the left and right sides can be closely attached to the inner wall of the tunnel, so that the water blocking construction device will not slide down even when encountering a large water pressure, improving the stability of the water blocking construction device; and, under the action of the support rod and the second friction block, the friction with the tunnel main body is further increased, enhancing the stability of the water blocking construction device; in addition, the main frame and the support rod are in a triangular structure, further improving the stability of the water blocking construction device.

[0018] 3. During the use of the present invention, leakage may occur at the top and side walls of the tunnel main body. By flexibly adjusting the first mounting plate and the second mounting plate, water blocking operations can be carried out at different positions of the tunnel main body, improving the practicability of the device. Moreover, during use, the length of the entire device can be adjusted according to the different leakage positions to carry out water blocking operations on the leakage at different positions of the tunnel main body.

[0019] In summary, the present invention can carry out water blocking operations on leaks at different positions and of different sizes of the tunnel main body, is easy to disassemble and assemble, can save disassembly and assembly time and labor costs, reduce safety hazards, and can improve the efficiency of water blocking construction operations.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 14 , the present invention provides a quick-disassembly and deep-buried underground tunnel water blocking construction device, including a support assembly 2, the support assembly 2 is arranged inside the tunnel main body 1, the support assembly 2 includes a main frame 201 arranged inside the tunnel main body 1, the number of the main frames 201 is two, and the two main frames 201 are distributed front and back, as Figure 4 shown.

[0025] As Figure 4 and Figure 7 shown, a servo motor 202 is fixedly installed at the central position inside the main frame 201, first threaded rods 203 are fixedly installed on the output shafts at the left and right ends of the servo motor 202, and slide bars 205 are slidably installed at both ends inside the main frame 201, and the slide bars 205 are in threaded rotation connection with the first threaded rods 203.

[0026] During the use process, when the servo motor 202 is started and the output shaft of the servo motor 202 drives the first threaded rods 203 at both left and right ends to rotate, the sliding rods 205 at both left and right ends can horizontally slide inside the main frame 201, thereby being able to change the length of the combination of the main frame 201 and the sliding rods 205.

[0027] One end of the sliding rod 205 located outside the main frame 201 has a U-shaped structure, and a brushless motor hub 206 is rotatably installed inside the U-shaped structure, as Figure 7 shown. The structure and principle of the brushless motor hub 206 are the same as those used in the rear wheels of two-wheel electric vehicles on the market. During the use process, the brushless motor is fixedly installed inside the sliding rod 205, and a hub for rotation is installed outside the brushless motor. After being powered on, under the action of the permanent magnet inside the brushless motor, the hub can rotate while the brushless motor does not rotate. Therefore, the brushless motor hub 206 in this device also uses the same principle. The brushless motor is fixedly installed on the inner side of the sliding rod 205, and the hub is nested on the outside. After being powered on, the hub can rotate, and the hub is in contact with the inner wall of the tunnel main body 1, so that the brushless motor hub 206 can move along the inner wall of the tunnel main body 1.

[0028] On the front and rear surfaces of one end of the sliding rod 205 located outside the main frame, a pair of first telescopic pumps 207 in a vertically symmetric state are symmetrically fixedly installed, as Figure 7 shown. The telescopic rods of the upper and lower first telescopic pumps 207 are jointly fixedly installed with a first friction block 208.

[0029] During the use process, when the sliding rod 205 and the main frame 201 move to an appropriate height, the telescopic rods of the first telescopic pumps 207 operate, and the telescopic rods of the first telescopic pumps 207 push the outer surface of the first friction block 208 to be in contact with the inner wall of the tunnel main body 1, thereby being able to increase the friction force. Under the action of the first friction block 208, it can be ensured that the sliding rod 205 and the main frame 201 will not slide down, thereby ensuring the stability of the main frame 201 and the sliding rod 205.

[0030] On the lower end surfaces of the front and rear main frames 201, inclined support assemblies 3 with the same structure are provided. The inclined support assembly 3 includes a main telescopic pump 301 arranged on the lower end surface of the main frame 201, and the upper end surface of the main telescopic pump 301 is in contact with the lower end surface of the main frame 201, as Figure 4As shown. A U-shaped fixing frame 302 is arranged outside the main telescopic pump 301. The opening of the U-shaped fixing frame 302 faces upward, such that the main frame 201 is located inside the U-shaped fixing frame 302. A buckle plate 303 is slidably installed at the upper opening of the U-shaped fixing frame 302. The lower end surface of the buckle plate 303 is in contact with the upper end surface of the main frame 201. Threads are provided at the upper opening of the U-shaped fixing frame 302, and a nut 304 is rotatably installed on the threaded opening of the U-shaped fixing frame 302. The lower end surface of the nut 304 is in contact with the upper end surface of the buckle plate 303, thereby enabling the U-shaped fixing frame 302 to be in a fixed state, and further enabling the main telescopic pump 301 to be in a fixed state, as Figure 4 shown.

[0031] At the left and right ends of the lower end of the main frame 201, two vertically distributed vertical plates 305 are symmetrically and fixedly installed. A cylinder is rotatably installed at the lower inner side of two adjacent vertical plates 305 in the front and rear. On both sides of the circumferential surface of the cylinder, rotating groove rods 306 are fixedly installed, as Figure 6 shown. A support rod 307 is fixedly installed on the circumferential surface of the cylinder and between the two rotating groove rods 306. A second friction block 308 is rotatably installed at the lower end of the support rod 307; among them, the support rod 307 and the second friction block 308 are rotatably installed in a strong damping rotation manner. Therefore, the rotation of the second friction block 308 requires manual adjustment by the operator to rotate, and the second friction block 308 will not rotate automatically at other times.

[0032] During the use process, when the telescopic rod of the main telescopic pump 301 retracts inward, it can drive the rotating groove rod 306 to rotate, and the rotating groove rod 306 will drive the support rod 307 to rotate synchronously. When the support rod 307 rotates, it can drive the second friction block 308 to rotate synchronously, thereby enabling the outer side of the second friction block 308 to be in close contact with the inner wall of the tunnel main body 1, and further forming an upward inclined support force to ensure the stability of the main frame 201 and the sliding rod 205.

[0033] It should be noted that one side of the rotating groove rod 306 is in a through state to the other side, and both sides of the end of the telescopic rod of the main telescopic pump 301 far from the main telescopic pump 301 protrude outward, and the protruding positions are rotatably installed inside the rotating groove rod 306, as Figure 6 shown.

[0034] During the use process, due to the rotation of the rotating groove rod 306, the structure in which the telescopic cylinder of the main telescopic pump 301 protrudes outward can slide inside the rotating groove rod 306, without mutual interference, ensuring the subsequent rotation of the support rod 307.

[0035] As Figure 4As shown in the figure, a pair of first rotating plates 501 are symmetrically and rotatably installed on the inner side surface of the main frame 201 at the front end, and a pair of second rotating plates 502 are symmetrically and rotatably installed on the inner side surface of the main frame 201 at the rear end. One end of the first rotating plate 501 far from the main frame 201 is rotatably installed inside the adjacent second rotating plate 502, as Figure 14 shown. Because there is a gap in the middle of the second rotating plate 502, the first rotating plate 501 can be rotatably installed inside it. Threaded columns 503 are rotatably installed at the upper ends of the two second rotating plates 502, threaded holes are formed on the circumferential surfaces of the two threaded columns 503, and an adjusting screw rod 504 is rotatably installed inside the two threaded holes, as Figure 14 shown.

[0036] During the use process, the operator rotates the adjusting screw rod 504 according to the leakage situation. The adjusting screw rod 504 can change the included angle between the first rotating plate 501 and the second rotating plate 502. When the included angle becomes larger, the distance between the front and rear main frames 201 can be made larger, and when the included angle becomes smaller, the distance between the front and rear main frames 201 will also become smaller. After adjusting the distance between the two main frames 201 to an appropriate position, select a first mounting plate 406 or a second mounting plate 408 with a suitable size according to the leakage situation and the leakage position, so as to be able to cope with the leakage gaps of different sizes and positions of the tunnel main body 1.

[0037] A water blocking assembly 4 is provided on the upper end surfaces of the two main frames 201. The water blocking assembly 4 includes two first connecting rods 401 rotatably installed on the left and right sides of the upper end surface of the main frame 201, as Figure 3 shown. One end of the first connecting rod 401 far from the main frame 201 is rotatably installed with a double-headed groove block 402. A second connecting rod 403 is rotatably installed inside the upper end of the double-headed groove block 402. One end of the second connecting rod 403 far from the double-headed groove block 402 is rotatably installed with a first mounting plate 406, as Figure 9 shown.

[0038] It should be noted that when the second connecting rod 403 is rotatably connected to the first mounting plate 406, a bolt and nut combination is used, so that different sizes of first mounting plates 406 can be replaced according to the leakage situation during subsequent operations.

[0039] As Figure 10 shown, a second mounting plate 408 can also be rotatably installed at one end of the second connecting rod 403 far from the double-headed groove block 402.

[0040] The first mounting plate 406 and the second mounting plate 408 are used for preventing and blocking leaks at different positions of the tunnel main body 1. Specifically, the first mounting plate 406 is used for preventing and blocking leaks at the top of the tunnel main body 1, and the second mounting plate 408 is used for preventing and blocking leaks at the side walls on both sides of the tunnel main body 1.

[0041] During use, since the inner top of the tunnel main body 1 is an arc structure while the two side walls are vertical structures, in order to ensure that the device can be applied to leaks at different positions of the tunnel main body 1, the rotational connections of the second connecting rod 403 with the first mounting plate 406 and the second mounting plate 408 all adopt a combination of bolts and nuts, which facilitates the disassembly and replacement of the first mounting plate 406 and the second mounting plate 408 according to the leak position.

[0042] Furthermore, water-blocking air cushions 407 are fixedly installed on the outer sides of both the first mounting plate 406 and the second mounting plate 408. During use, the outer side surface of the water-blocking air cushion 407 can closely fit the top and side walls of the tunnel main body 1, and according to different use positions, the shapes of the water-blocking air cushions 407 are also different. For example, Figure 9 and Figure 10 as shown, one of the two water-blocking air cushions 407 is an arc structure and the other is a vertical structure, enabling them to be applicable to the arc structure of the top of the tunnel main body 1 and the vertical structure of the side wall.

[0043] For example, Figure 9 as shown, first motors 404 are fixedly installed on the left side surfaces of the two double-headed groove blocks 402 on the left side. A reciprocating lead screw 405 is fixedly installed on the output shaft of the first motor 404, and the reciprocating lead screw 405 is in threaded rotational connection with the two double-headed groove blocks 402 on the left and right sides.

[0044] During use, when the first motor 404 is started, the output shaft of the first motor 404 will drive the reciprocating lead screw 405 to rotate. When the reciprocating lead screw 405 rotates, it can make the distance between the two double-headed groove blocks 402 on the left and right sides become larger or smaller, thereby being able to change the angle between the first connecting rod 401 and the second connecting rod 403. In this way, it can push the first mounting plate 406 and the second mounting plate 408 closer to or farther away from the inner side of the tunnel main body 1, so that the water-blocking air cushion 407 is closer to or farther away from the inner wall of the tunnel main body 1.

[0045] Furthermore, a connection threaded hole 204 is opened at one end of the first threaded rod 203 away from the servo motor 202. A connection threaded head 210 is rotatably installed inside the connection threaded hole 204. One end on the outer side of the connection threaded head 210 is fixedly installed with a connection threaded rod 209, and the slide rod 205 is in threaded rotational connection with the connection threaded rod 209, as Figure 13 shown.

[0046] Combined with Figure 2, during the use process, due to the height problem of the tunnel main body 1, it is necessary to adjust the position of the sliding rod 205. By rotating and installing the connecting threaded head 210 inside the connecting threaded hole 204, fixedly installing the connecting threaded rod 209 at one end of the connecting threaded head 210, and threadedly connecting the sliding rod 205 with the connecting threaded rod 209, the length of the entire device can be increased. Among them, the threads and diameters of the connecting threaded rod 209 and the first threaded rod 203 are the same to ensure the installation of the sliding rod 205, as Figure 12 shown.

[0047] In addition, when the lengths of the main frame 201 and the sliding rod 205 of a set of devices still cannot meet the usage requirements in the tunnel main body 1, two main frames 201 can also be combined together. For example, the adjacent ends of the main frames 201 that are close to each other are connected by a combination structure of bolts and nuts, so as to facilitate disassembly operations while increasing the overall length of the device. It should be noted that during the use process, no matter how many main frames 201 are combined and installed on the left and right sides of the subsequent tunnel main body 1, a servo motor 202 does not need to be fixedly installed inside, as Figure 2 the main frame 201 added later in the upper middle part does not install a servo motor 202, and the combined main frames 201 are only used to adjust the length of the entire device.

[0048] Working principle of the present invention: First, assemble the device outside the tunnel main body 1 to save subsequent installation time.

[0049] Next, start the servo motor 202. The output shaft of the servo motor 202 drives the first threaded rods 203 at both left and right ends to rotate, causing the sliding rods 205 at both left and right ends to slide horizontally inside the main frame 201, thereby changing the combined length of the main frame 201 and the sliding rod 205.

[0050] Then, rotate the adjusting screw rod 504 to adjust the angle between the first rotating plate 501 and the second rotating plate 502 to an appropriate angle; Next, start the brushless motor hub 206. After the sliding rod 205 and the main frame move upward to an appropriate height, start the first telescopic pump 207. The telescopic rod of the first telescopic pump 207 makes the first friction block 208 fit against the inner wall of the tunnel main body 1.

[0051] Next, start the main telescopic pump 301. The telescopic rod of the main telescopic pump 301 retracts inward, the rotating groove rod 306 rotates, the rotating groove rod 306 drives the support rod 307 to rotate, and the support rod 307 drives the second friction block 308 to rotate, making the outer side of the second friction block 308 fit tightly against the inner wall of the tunnel main body 1.

[0052] Finally, start the first motor 404. The output shaft of the first motor 404 drives the reciprocating lead screw 405 to rotate, adjust the distance between the two double-headed groove blocks 402, thereby changing the angle between the first connecting rod 401 and the second connecting rod 403, and push the first mounting plate 406 or the second mounting plate 408 close to the leakage position of the tunnel main body 1, and plug the water through the water blocking air cushion 407.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
