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 deeply buried underground tunnels that can be quickly disassembled and assembled. Background Art

[0002] At present, the underground tunnel project has developed rapidly. During the construction in the underground water-rich area, poor hydrogeological conditions such as water seepage, dripping water, and water inrush are often encountered. Large water inrush in the hole is often encountered, and it is necessary to stop the excavation and carry out 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 scaffolds before 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 scaffolds, due to the reasons of the tunnel scaffolds and the internal space, the construction time is relatively long. Secondly, due to the long time for setting up the scaffolds, it is impossible to carry out water plugging construction operations 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 erected scaffolds, it will take a lot of time to complete the disassembly operation. Moreover, since the scaffolds need to be disassembled from high to low, it will require the cooperation of multiple people to complete the operation. In order to speed up the disassembly and assembly efficiency, it is necessary to equip multiple workers to complete the disassembly operation. This method not only increases the personnel cost, but also, it is difficult to avoid interference due to the increase in personnel, 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 improve the disassembly and assembly efficiency, we specifically propose a water plugging construction device for deeply buried underground tunnels that can be quickly disassembled and assembled.

[0013] Preferably, first telescopic pumps are fixedly installed on the front and rear surfaces of one end of the sliding rod located outside the main frame in a vertically symmetric state. A first friction block is fixedly installed on the telescopic rods of the two first telescopic pumps up and down. The outer side surface of the first friction block can be attached to the inner wall of the tunnel main body.

[0014] Preferably, a first motor is fixedly installed on the left side surface of the left double-headed groove block. A reciprocating lead screw is fixedly installed on the output shaft of the first motor. The two double-headed groove blocks on the left and right sides are threadedly and rotatably installed on the circumferential surface of the reciprocating lead screw.

[0015] Preferably, a diagonal support assembly is provided on the lower end surface of the main frame. The diagonal support assembly includes a main telescopic pump arranged on the lower end surface of the main frame. A U-shaped fixing frame is arranged outside the main telescopic pump. The opening of the U-shaped fixing frame faces upward.

[0016] Preferably, a buckle plate is slidably installed at the upper opening of the U-shaped fixing frame. The lower end surface of the buckle plate is attached to the upper end surface of the main frame. A nut is threadedly and rotatably installed at the opening of the U-shaped fixing frame.

[0020] Preferably, a connection threaded hole is opened at one end of the first threaded rod away from the servo motor.

One end on the outer side of the connection threaded head is fixedly installed with a connection threaded rod, and the sliding rod is in threaded rotation connection with the connection threaded rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 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 fitted to the leaking place of the tunnel main body, so as to complete the water blocking operation on the leaking place, facilitating the operators to carry out the next operation; 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 when the whole device moves to a suitable height, two construction workers 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; in addition, when carrying out the water blocking operation on the side wall of the tunnel main body, only the first friction blocks at the upper and lower positions of the main frame need to be separated from the top and bottom of the tunnel main body to complete the disassembly and assembly operation, saving the disassembly time.

[0023] 2. During the operation of the present invention, the first friction blocks on the left and right sides can be closely fitted 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 form a triangular structure, further improving the stability of the water blocking construction device.

[0024] 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.

[0025] 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 potential safety hazards, and can improve the efficiency of water blocking construction operations.

[0047] 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.

[0048] 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.

[0049] 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, sliding rods 205 are slidably installed at both ends inside the main frame 201, and the sliding rods 205 are in threaded rotation connection with the first threaded rods 203.

[0050] During the use process, when the servo motor 202 is started and the output shafts of the servo motor 202 drive the first threaded rods 203 at the left and right ends to rotate, the sliding rods 205 at the left and right ends can horizontally slide inside the main frame 201, so as to change the length of the combination of the main frame 201 and the sliding rods 205.

[0051] One end of the sliding rod 205 located outside the main frame 201 is of 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-wheeled 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, the hub can rotate under the action of the permanent magnet inside the brushless motor, 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.

[0052] A pair of first telescopic pumps 207 in a vertically symmetric state are symmetrically and fixedly installed on the front and rear surfaces of one end of the sliding rod 205 located outside the main frame, as Figure 7 shown, and the telescopic rods of the upper and lower first telescopic pumps 207 are jointly fixedly installed with a first friction block 208.

[0053] During the use process, the sliding rod 205 and the main frame 201 move to an appropriate height, and the telescopic rod of the first telescopic pump 207 operates. The telescopic rod of the first telescopic pump 207 pushes the outer side of the first friction block 208 to fit against the inner wall of the tunnel main body 1, thereby increasing 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.

[0054] The lower end surfaces of the front and rear main frames 201 are both provided with diagonal support assemblies 3 with the same structure. The diagonal support assembly 3 includes a main telescopic pump 301 arranged on the lower end surface of the main frame 201. The upper end surface of the main telescopic pump 301 is in a fitting state with the lower end surface of the main frame 201, as Figure 4 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, so that the main frame 201 is inside the U-shaped fixing frame 302. A snap plate 303 is slidably installed at the upper opening of the U-shaped fixing frame 302. The lower end surface of the snap plate 303 is in a fitting state with the upper end surface of the main frame 201. The upper opening of the U-shaped fixing frame 302 is provided with threads, 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 snap plate 303, so as to keep the U-shaped fixing frame 302 in a fixed state, and further keep the main telescopic pump 301 in a fixed state, as Figure 4 shown.

[0055] Two vertical plates 305 distributed front and back are symmetrically and fixedly installed at the left and right ends of the lower end of the main frame 201. A cylinder is rotatably installed at the lower inner side of the front and rear adjacent vertical plates 305. Rotating groove rods 306 are fixedly installed on both sides of the circumferential surface of the cylinder, 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. The lower end of the support rod 307 is rotatably installed with a second friction block 308; among them, the support rod 307 and the second friction block 308 are rotatably installed in a strong damping rotation mode. 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 by itself at other times.

[0056] 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, so as to make the outer side of the second friction block 308 closely fit against the inner wall of the tunnel main body 1, thereby forming an upward diagonal support force to ensure the stability of the main frame 201 and the sliding rod 205.

[0057] 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.

[0058] During the use process, due to the rotation of the rotating groove rod 306, the structure where the telescopic cylinder of the main telescopic pump 301 protrudes outward can slide inside the rotating groove rod 306, without interference, ensuring the rotation of the subsequent support rod 307.

[0059] As Figure 4 shown, a pair of first rotating plates 501 are symmetrically and rotatably installed on the inner side surface of the front end of the main frame 201, and a pair of second rotating plates 502 are symmetrically and rotatably installed on the inner side surface of the rear end of the main frame 201. 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 provided 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.

[0060] 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 increased, 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 the first mounting plate 406 or the second mounting plate 408 with appropriate dimensions according to the leakage situation and leakage position, so as to cope with the leakage gaps of different sizes and positions of the tunnel main body 1.

[0061] Water blocking assemblies 4 are provided on the upper end surfaces of the two main frames 201. The water blocking assemblies 4 include 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.

[0062] 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 during subsequent operations, the first mounting plate 406 of different sizes can be replaced according to the leakage situation.

[0063] As Figure 10 shown, a second mounting plate 408 can also be rotatably installed at one end of the second connecting rod 403 away from the double-headed groove block 402.

[0064] The first mounting plate 406 and the second mounting plate 408 are used for preventing blockage of leakage at different positions of the tunnel main body 1. Specifically, the first mounting plate 406 is used for preventing blockage of leakage at the top of the tunnel main body 1, and the second mounting plate 408 is used for preventing blockage of leakage at the side walls on both sides of the tunnel main body 1.

[0065] During use, since the inner top of the tunnel main body 1 is an arc structure, while the side walls on both sides are vertical structures, therefore, to ensure that the device can be applied to leakage at different positions of the tunnel main body 1, the rotational connections between the second connecting rod 403 and the first mounting plate 406 and the second mounting plate 408 all adopt a bolt and nut combination, which facilitates the disassembly and replacement of the first mounting plate 406 and the second mounting plate 408 according to the leakage position.

[0066] Furthermore, water-blocking air cushions 407 are fixedly installed on the outer sides of the first mounting plate 406 and the second mounting plate 408. During use, the outer side surfaces of the water-blocking air cushions 407 can closely fit with the top and side walls of the tunnel main body 1, and the shapes of the water-blocking air cushions 407 are different according to different use positions. As Figure 9 and Figure 10 shown, one of the two water-blocking air cushions 407 is an arc structure and the other is a vertical structure, so that they can be applied to the arc structure of the top of the tunnel main body 1 and the vertical structure of the side walls.

[0067] As Figure 9 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.

[0068] 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 as to make the water-blocking air cushion 407 closer to or farther away from the inner wall of the tunnel main body 1.

[0069] Furthermore, a connection threaded hole 204 is formed 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 outside the connection threaded head 210 is fixedly installed with a connection threaded rod 209. The slide rod 205 is in threaded rotational connection with the connection threaded rod 209, as Figure 13 shown.

[0070] 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 slide rod 205. By rotatably installing the connection threaded head 210 inside the connection threaded hole 204, fixedly installing the connection threaded rod 209 at one end of the connection threaded head 210, and threading the slide rod 205 with the connection threaded rod 209, the length of the entire device can be increased. Among them, the threads and diameters of the connection threaded rod 209 and the first threaded rod 203 are the same to ensure the installation of the slide rod 205, as Figure 12 shown.

[0071] In addition, when the lengths of the main frame 201 and the slide rod 205 of a set of devices still cannot meet the usage requirements in the tunnel main body 1, two main frames 201 can 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 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, the servo motor 202 does not need to be fixedly installed inside, such as Figure 2 the main frame 201 added later in the upper middle part does not install the servo motor 202, and the combined main frame 201 is only used to adjust the length of the entire device.

[0072] The working principle of the present invention:

[0073] First, assemble the device outside the tunnel main body 1 to save subsequent installation time.

[0074] Then, 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, so that the slide rods 205 at both left and right ends slide horizontally inside the main frame 201, thereby changing the combined length of the main frame 201 and the slide rod 205.

[0075] Next, 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;

[0076] Next, start the brushless motor hub 206. After the slide bar 205 and the main frame 201 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 body 1.

[0077] 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, so that the outer side of the second friction block 308 fits tightly against the inner wall of the tunnel body 1.

[0078] Finally, start the first motor 404. The output shaft of the first motor 404 drives the reciprocating lead screw 405 to rotate, adjusts 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 pushes the first mounting plate 406 or the second mounting plate 408 close to the leakage position of the tunnel body 1, and plugs the water through the water blocking air cushion 407.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit 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 for 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.
