[0017] (III) Beneficial effects

[0018] The invention provides a comprehensive equipment for water and mud gushing for mountain plateau tunnel construction, which has the following beneficial effects:

[0019] 1. By setting the first connecting tube and the rubber tube and the connecting assembly distributed along the circumference of the connecting shell, the rubber tube can automatically expand outward under the action of the third spring and the connecting block, and the third spring can push the rubber tube outward, so that the rubber tube can block the position where water gushes and mud bursts, and the device can install the pump body at the position of the connecting tube so that the rubber tube can be filled with fluid, so as to subsequently prop up the wrinkled area outside the rubber tube, thereby realizing the blocking function of the position where water gushes and mud bursts.

[0020] 2. Through the setting of the connecting component, the second electric push rod on the connecting component is used to push the third connecting rod, so that the third connecting rod slides inside the second fixed tube, thereby adjusting the closed or connected state of the first connecting groove. When the first connecting groove is in the connected state, the device can guide the gushing water into the extension key cylinder through the through hole on the second extension tube, and by extending the first electric push rod, the spline rod is moved out of the extension key cylinder, so that the gushing water can be automatically injected into the second connecting groove connected to the extension key cylinder. As the water pressure increases, the gushing water in the second connecting groove can push the sealing block to send the water into the connecting shell, and send it into the rubber tube through the first connecting tube on the connecting shell, so that the outer periphery of the rubber tube expands, thereby realizing the automatic sealing function. The device can select the sealing method according to the gushing water conditions. When there is a lot of mud, fluid can be injected for sealing through an external pump. When there is a lot of water gushing, the water pressure of the gushing water can be used to fill the rubber tube for automatic sealing, which solves the problem that the existing water gushing and mud gushing equipment cannot automatically expand outward after blocking the mud and water gushing position to ensure the sealing effect.

[0021] 3. By setting up a motor, a spline rod that passes through the front and back, a shell, a first extension tube, a second extension tube and a spiral plate, the motor drives the spline rod to rotate, and the spline rod can drive the shell to rotate after being stuck in the shell. When the first extension tube and the second extension tube are rotating, the spiral plate can be screwed into the soil, so that the shell as a whole can remain stable. According to the position where the spiral plate is easy to fix, the first extension tube and the second extension tube are screwed into the soil layer of different depths, so that the shell can be automatically clamped after being tightened, thereby ensuring the safety of the device during use, and solving the problem that the existing water gushing and mud bursting treatment equipment cannot keep the outside of the device stably clamped and adjust the clamping position after blocking.

[0043] Embodiment 2:

[0044] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0045] like Figure 1 and Figure 7 As shown, as a preferred embodiment, on the basis of the above method, further, the first support assembly 1 includes a first support plate 101, an outer bushing 102 is welded on the first support plate 101, a ball shaft 103 is rotatably installed in the outer bushing 102, the motor 2 and the ball shaft 103 are fixedly connected, and the ball shaft 103 can change the overall angle of the motor 2, so as to subsequently adjust the blocking position of the device according to the position of the gushing water and mud. The first support plate 101 is used to support the outer bushing 102, and the motor 2 can change its installation angle on the outer bushing 102 through the ball shaft 103, thereby changing the installation angle of the device as a whole.

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the second support assembly 3 includes a first electric push rod 301 fixedly connected to the motor 2, a second support plate 302 fixedly connected to the first electric push rod 301, a first fixed tube 304 fixedly arranged on the second support plate 302, a first connecting rod 303 slidably installed in the first fixed tube 304, a first spring 307 fixedly connected between the first connecting rod 303 and the first fixed tube 304, a third support plate 305 fixedly arranged on the first fixed tube 304, a second connecting rod 306 welded on the third support plate 305, and a second connecting rod 306 and a connecting shell 8 are fixedly connected. The device can synchronously extend or shorten the first electric push rod 301, thereby changing the distance between the motor 2 and the second support plate 302. When the first electric push rod 301 is shortened, the first connecting rod 303 will slide in the first fixed tube 304, thereby compressing the first spring 307, and the overall connectivity state can be changed by adjusting the position of the motor 2.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the first electric push rod 301 and the first connecting rod 303 are symmetrically distributed on both sides of the second support plate 302, the central axes of the spline rod 4, the spline sleeve 5, the second support plate 302 and the third support plate 305 are all collinear, and the two symmetrically distributed groups of the first electric push rod 301 and the first connecting rod 303 can enable the device to stably adjust the position of the spline rod 4 in the spline sleeve 5.

[0048] like Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the second support plate 302 and the third support plate 305 are rotationally connected to the spline sleeve 5, and the first fixed tube 304, the third support plate 305, the second connecting rod 306 and the connecting shell 8 are fixedly connected as an integral structure to ensure the overall stability of the device. When the angle of the spline sleeve 5 changes, the overall angle of the first fixed tube 304, the third support plate 305, the second connecting rod 306 and the connecting shell 8 will change.

[0049] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the connecting component 6 includes a first rotating ring 601 rotatably mounted on the spline sleeve 5, a second electric push rod 602 is mounted on the first rotating ring 601, a third connecting rod 603 is fixedly connected to the second electric push rod 602, a fixed rod 606 is fixedly arranged on the spline sleeve 5, an extended key cylinder 607 is fixedly connected to the fixed rod 606, a second rotating ring 605 is rotatably mounted on the spline sleeve 5 and the extended key cylinder 607, and the rotatably mounted first rotating ring 601 and second rotating ring 605 ensure that the first rotating ring 601 and the second rotating ring 605 will not be affected by the rotation of the spline sleeve 5. A second fixed tube 604 is fixedly provided on one side of the second rotating ring 605, and a connecting tube 608 is fixedly provided on the other side of the second rotating ring 605. A first connecting groove 609 is provided in the second fixed tube 604 and the second rotating ring 605. When the second electric push rod 602 is extended, it will drive the third connecting rod 603 to slide in the second fixed tube 604, so as to choose to block the first connecting groove 609 or open the first connecting groove 609. When there is a lot of water gushing in the tunnel, the first connecting groove 609 can be opened so that the water pressure of the gushing water can be used to guide the water to other positions later, thereby enhancing the adjustability of the device.

[0050] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, there is a gap between the extended key cylinder 607 and the spline sleeve 5, the spline rod 4 is connected from head to tail, and the inner walls of the extended key cylinder 607, the spline sleeve 5 and the docking groove 19 are all in contact with the outer wall of the spline rod 4. When the spline rod 4 rotates, the extended key cylinder 607 and the spline sleeve 5 rotate synchronously. Subsequently, the device as a whole can be screwed in and installed by processing the spline rod 4 and docking the spline rod 4 with the docking groove 19. The spline rod 4 can be shortened so that the spline rod 4 and the interior of the extended key cylinder 607 are connected to each other, thereby discharging the fluid in the device.

[0051] like Fig.14 and Fig.15As shown, as a preferred embodiment, on the basis of the above method, further, the sealing assembly 13 includes a second connecting tube 1302 fixedly connected to the inside of the connecting shell 8, a second spring 1303 is fixedly arranged in the second connecting tube 1302, a sealing block 1301 is fixedly connected to the second spring 1303, and the outer wall of the sealing block 1301 away from the second spring 1303 is in contact with the inner wall of the feed port 12. When the water pressure is too high, the water flow will impact the sealing block 1301, so that the second spring 1303 in the second connecting tube 1302 is compressed, and water is automatically injected into the interior of the connecting shell 8.

[0052] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the rubber tube 14 is evenly distributed along the circumference of the connecting shell 8, the side of the rubber tube 14 is wrinkled, the rubber tube 14 forms an elastic structure through the third spring 15 and the connecting block 16, the interior of the rubber tube 14 is interconnected with the interior of the connecting shell 8 through the first connecting tube 10, and the connecting shell 8 is provided with a groove 11 for placing the first connecting tube 10. The first connecting tube 10 is bent, and there is a gap between the bent part of the first connecting tube 10 and the connecting shell 8. The third spring 15 can be used to keep the rubber tubes 14 at various locations on the device in a state of being stretched outward at all times, and when the internal pressure of the connecting shell 8 gradually increases, the fluid can be pumped into the rubber tube 14 through the first connecting tube 10, so that the rubber tube 14 expands outward, and multiple rubber tubes 14 with external wrinkles can abut against each other after being stretched out, and block the position where water and mud burst out.

[0053] like Fig. 9 and Fig.11 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the first extension tube 20, the second extension tube 21 and the outer shell 7 are fixedly connected as an integral structure to ensure the overall stability of the device. The outer shell 7 is connected to the inner groove 24 in the second extension tube 21 through the third connecting groove 18. The outer shell 7 is fixedly connected with a connecting block 9. After the gushing water enters the inner groove 24, the water can be pumped into the outer shell 7 through the third connecting groove 18. After the second extension tube 21 is screwed into the soil layer, the water can be diverted to the position of the third connecting groove 18 through the inner groove 24, so as to subsequently send the gushing water into the interior of the device.

[0054] Embodiment 3:

[0055] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0056] Specifically, when using the comprehensive equipment for water and mud gushing for mountain plateau tunnel construction: Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the first support plate 101 on the first support assembly 1 is used to support the outer bushing 102. The installation angle of the motor 2 on the outer bushing 102 can be changed by the ball shaft 103 to adapt to different water and mud bursting positions for plugging. After adjusting the angle of the motor 2, the spacing between the motor 2 and the second support plate 302 on the second support assembly 3 can be changed by extending or shortening the first electric push rod 301. When the first electric push rod 301 is shortened, the first spring 307 is compressed, and the first connecting rod 303 slides in the first fixed tube 304. The position of the spline rod 4 in the spline sleeve 5 can be changed by adjusting the position of the motor 2. When the spline rod 4 is docked with the docking groove 19 on the shell 7, the spline rod 4 will drive the shell 7 to rotate when it rotates. Since the first extension tube 20, the second extension tube 21 and the shell 7 are a whole, when the shell 7 rotates, the spiral plate 22 on the outside of the second extension tube 21 will be screwed into the soil layer. After the spiral plate 22 is embedded in the soil, the device as a whole can be kept fixed. The second connecting rod 306 on the third supporting plate 305 is used to support the connecting shell 8 .

[0057] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 , Fig.13 , Fig.14 and Fig.16 As shown, when the spiral plate 22 is embedded in the soil layer, the gushing water will flow into the inner groove 24 through the through hole 23 on the second extension pipe 21, and enter the second fixed pipe 604 in the connecting component 6 through the inner groove 24 and the third connecting groove 18 (combined with Figure 3 , Figure 5 and Fig.10 As can be seen), the first rotating ring 601 and the second rotating ring 605 rotatably installed in the connecting component 6 ensure that the second fixed pipe 604 will not be adversely affected when the spline sleeve 5 rotates. When the second electric push rod 602 is extended, it will drive the third connecting rod 603 to slide in the second fixed pipe 604. The device can choose to block the first connecting groove 609 or open the first connecting groove 609. When there is a lot of water in the tunnel, by opening the first connecting groove 609, the first electric push rod 301 is shortened, so that the spline rod 4 slides toward a position away from the fixed rod 606 and the extension key cylinder 607, and a plug cover is connected to the position of the connecting pipe 608. At this time, the water flows through the extension key cylinder 607 and the second connecting groove 17 into the feed port 12 in the connecting shell 8. Figure 3 and Fig.15 As shown, when in use, it is necessary to ensure that the connecting block 9 is in close contact with the connecting shell 8 and Figure 3The triangle mark on the middle shell 7 is aligned with the triangle mark on the connecting shell 8. At this time, the second connecting groove 17 is aligned with the feed port 12. As the water pressure gradually increases, the water flow will push the sealing block 1301, compressing the second spring 1303 in the second connecting pipe 1302, so that water is automatically injected into the connecting shell 8 and enters the rubber tube 14 through the first connecting pipe 10. Figure 5 As shown, when the water inflow is small, the third connecting rod 603 can be blocked by the second electric push rod 602, and the pump body can be connected to the connecting pipe 608 to inject the fluid into the rubber tube 14. When the pressure in the rubber tube 14 increases, the wrinkled part of the edge of the rubber tube 14 will be stretched open, and the adjacent rubber tubes 14 will be close to each other and keep sealed. At the same time, the rubber tube 14 can also block the position of the water inflow and mud, and the spiral plate 22 embedded in the soil can keep the device fixed as a whole. After the fixation is completed, the first electric push rod 301 is extended so that the spline rod 4 extends to the docking groove 19 to complete the blocking work.

[0058] The above embodiments are only used to illustrate the present invention, but not to limit the present invention.
