Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a tunnel water inrush grouting device. Background Technology

[0002] Water inrush, also known as sudden water inrush, is a sudden and large-scale water inrush that occurs during the construction of underground chambers and tunnels, especially when passing through areas with developed karst caves, underground river systems, thick layers of water-bearing gravel, and large fractured zones connected to surface water. It poses a great threat to the construction of underground engineering projects. Due to the complexity and unpredictability of karst, the presence of hidden karst and high-pressure water around the tunnel directly affects construction safety. Therefore, geological work such as advanced geological prediction and forecasting and exploration of surrounding karst is necessary during the construction of karst tunnels.

[0003] When tunnels pass through water-rich karst areas such as fault fracture zones and filled karst caves, grouting pre-reinforcement and water plugging measures should be taken. When grouting water inflow holes, a mixture of cement grout and water glass is used for filling. Therefore, a dual-liquid grouting machine is used for filling. During the grouting process, after the grouting of one grouting point is completed, the grouting operation of the next grouting point must be carried out as soon as possible. Otherwise, the grout will solidify quickly, causing blockage of the grout output pipe and affecting the next grouting operation. Summary of the Invention

[0004] In view of the problem in the above or existing technology that during the grouting process, after the grouting of one grouting point is completed, the grouting operation of the next grouting point must be carried out as soon as possible, otherwise the grout will solidify quickly, causing blockage of the grout output pipe and affecting the next grouting operation, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a tunnel water inrush grouting device.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tunnel water inrush grouting device, including a grouting mechanism, which includes a carrier vehicle, a power box fixed on the carrier vehicle, and a transmission component connected to the power box;

[0007] The connecting mechanism includes a connecting pipe, a rotating component connected to the connecting pipe, a clamping component disposed on the rotating component, a mixing tank, a docking component disposed on the mixing tank, and an unlocking component fixed on the docking component.

[0009] In a preferred embodiment of the tunnel water inrush grouting device of the present invention, the connecting pipe includes a pipe body, a sliding groove formed on the pipe body, a rotating groove connected to the sliding groove, and a limiting groove formed on the rotating groove.

[0010] As a preferred embodiment of the tunnel water inrush grouting device of the present invention, the limiting groove includes a groove body, the groove body includes a transition surface, a contact surface connected to the transition surface, a snap-fit ​​surface disposed on the groove body, and a snap-fit ​​hole disposed on the snap-fit ​​surface.

[0011] As a preferred embodiment of the tunnel water inrush grouting device of the present invention, the rotating component includes a connecting ring, a first clamping plate disposed on the connecting ring, a first clamping block fixed on the connecting ring, a second clamping plate fixed on the connecting ring, and a semi-circular block disposed on the connecting ring.

[0012] As a preferred embodiment of the tunnel water inrush grouting device of the present invention, the clamping assembly includes a rectangular groove disposed on the first clamping plate, a toothed block disposed on the rectangular groove, and a protruding plate disposed on the first clamping plate.

[0013] As a preferred embodiment of the tunnel water inrush grouting device of the present invention, the docking assembly includes a docking pipe, a third clamping plate disposed on the docking pipe, a second clamping block fixed on the docking pipe, and a fixing member disposed on the second clamping block.

[0014] In a preferred embodiment of the tunnel water inrush grouting device of the present invention, the second clamping block includes a block body, the block body is provided with an installation groove, the block body is provided with an inclined surface, and the first clamping block is connected to the third clamping plate.

[0015] As a preferred embodiment of the tunnel water inrush grouting device of the present invention, the fixing member includes a fixed shaft, a rotating block connected to the fixed shaft, a trapezoidal groove formed on the rotating block, and an arc surface connected to the trapezoidal groove.

[0016] In a preferred embodiment of the tunnel water inrush grouting device of the present invention, the unlocking component includes an unlocking rod, a disc disposed on the unlocking rod, and a reset spring disposed on the unlocking rod.

[0017] The beneficial effects of the tunnel water inrush grouting device of the present invention are as follows: The present invention connects a connecting pipe threaded onto the discharge pipe, and a connecting ring is connected to the connecting pipe. The connecting ring can slide and rotate on the connecting pipe. When the connecting ring rotates into the rotating groove, the limiting groove on the inner wall of the rotating groove will limit the semi-circular block on the connecting ring, so that the connecting ring can be fixed at the end of the connecting pipe. Then, the connecting pipe is inserted into the connecting pipe on the mixing tank, and then the connecting pipe is rotated. The first clamping plate and the second clamping plate on the connecting ring will be locked onto the second clamping block on the inner wall of the connecting pipe. The third clamping plate on the inner wall of the connecting pipe will lock onto the first clamping block on the connecting ring, thus initially fixing the connecting ring inside the connecting pipe. When the first clamping plate rotates to the second clamping block, the toothed block will lock into the trapezoidal groove on the rotating block, thus further clamping the connecting ring and firmly fixing the connecting pipe to the mixing cylinder. During the grouting operation at the next grouting point, the discharge pipe can be quickly connected to the mixing cylinder, thus preventing the mixture from stopping flowing in the discharge pipe, avoiding the mixture from quickly solidifying in the discharge pipe, and preventing the discharge pipe from becoming blocked.

[0032] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a tunnel water inrush grouting device, including a grouting mechanism 100, which includes a carrier vehicle 101 and a power box 102 fixed on the carrier vehicle 101. The power box 102 can provide power to the transmission component 103 to draw the required cement slurry and water glass into the transmission component 103. The transmission component 103 is connected to the power box 102 and fixed on one side of the power box 102. Through the transmission component 103, the material for sealing the water inrush hole can be injected into the hole, thereby achieving the sealing effect.

[0033] The connecting mechanism 200 includes a connecting pipe 201 fixed to the end of the transmission component 103, a rotating component 202 connected to the connecting pipe 201 and slidably connected to the outer surface of the connecting pipe 201, a clamping component 203 disposed on the rotating component 202 and fixed inside the rotating component 202, which can limit the rotation component 202, and also includes a mixing tank 204, which is a device for storing a mixture of water glass and cement slurry, a docking component 205 disposed on the mixing tank 204 and fixed to the upper end of the outer surface of the mixing tank 204, and an unlocking component 206 fixed on the docking component 205, which can release the connection between the rotating component 202 and the docking component 205.

Two connecting plates 103b are fixedly connected to the transport pipe 103a. The connecting plates 103b are used to connect a first inlet pipe 103c and a second inlet pipe 103d. The first inlet pipe 103c and the second inlet pipe 103d are connected to the connecting plate 103b and fixed to the transport pipe 103a via the connecting plates 103b. A first outlet pipe is fixed to the connecting plate 103b. 103e is connected to the second outlet pipe 103f, the first outlet pipe 103e is connected to the first inlet pipe 103c, the second outlet pipe 103f is connected to the second inlet pipe 103d, and an adapter 103g is connected to the first outlet pipe 103e and the second outlet pipe 103f. The adapter 103g is threadedly connected to the first outlet pipe 103e and the second outlet pipe 103f. The two materials can be mixed together through the adapter 103g. The discharge pipe 103h is threadedly connected to the adapter 103g, and a connecting pipe 201 is threadedly connected to the discharge pipe 103h.

[0035] The connecting pipe 201 includes a pipe body 201a, a sliding groove 201b formed on the pipe body 201a, the sliding groove 201b being formed on the outer surface of the connecting pipe 201, and two annular sliding grooves 201b being formed on the connecting pipe 201, a rotating groove 201c connected to the sliding groove 201b, the rotating groove 201c being connected to the sliding groove 201b, the sliding groove 201b and the rotating groove 201c being connected to form an L-shape, a limiting groove 201d being formed on the rotating groove 201c, the limiting groove 201d being formed on the inner wall of the rotating groove 201c.

[0036] Furthermore, the limiting groove 201d includes a groove body 201d-1, and the groove body 201d-1 includes a transition surface 201d-2. The transition surface 201d-2 is formed at the transition point on the inner wall of the rotating groove 201c. The transition surface 201d-2 has an inclination of less than 30 degrees. If the inclination angle of the transition surface 201d-2 is greater than 30 degrees, it will prevent the rotating component 202 from being limited. The contact surface connected to the transition surface 201d-2... 201d-3, the contact surface 201d-3 is connected to the transition surface 201d-2, the snap-fit ​​surface 201d-4 is set on the groove body 201d-1, the snap-fit ​​surface 201d-4 is connected to the contact surface 201d-3, the snap-fit ​​surface 201d-4 and the contact surface 201d-3 form a height difference, and the snap-fit ​​hole 201d-5 is set on the snap-fit ​​surface 201d-4, the snap-fit ​​hole 201d-5 is set on one side of the snap-fit ​​surface 201d-4.

[0037] Operational Procedure: During tunnel construction, water inrush may occur due to geological conditions. Workers typically address this issue by using pre-grouting. When injecting grout into the borehole, a mixture of cement grout and water glass is usually used. This mixture increases hardness and accelerates setting, improving the sealing effect on the inrush hole. During grouting, two different liquid intake pipes (103c and 103d) are used to draw in the grout, which is then discharged through the first outlet pipe (103e) and the second outlet pipe (103f). An adapter (103g) is connected to the outlet of the first outlet pipe (103e) and the second outlet pipe (103f), and the adapter (103g) is connected to an outlet pipe. A connecting pipe 201 is connected to the outlet of the discharge pipe 103h. The mixture of cement and water glass will be discharged from the connecting pipe 201. Since the mixture sets quickly, but there is still a distance between each water inlet, it is necessary to keep the discharge pipe 103h flowing after each grouting is completed. Otherwise, the discharge pipe 103h may become blocked. In order to keep the discharge pipe 103h flowing and to avoid wasting materials, the outlet of the connecting pipe 201 is clamped to the docking component 205 on the mixing tank 204 by the rotating component 202. The material in the discharge pipe 103h will keep flowing, and the material in the discharge pipe 103h can flow into the mixing tank 204. At the same time, the discharge pipe 103h will not become blocked.

[0038] Example 2, refer to Figures 1 to 6This is the second embodiment of the present invention. Unlike the previous embodiment, the rotating assembly 202 includes a connecting ring 202a, which is slidably connected to a sliding groove 201b via a semi-circular block 202e. The sliding groove 201b is adapted to the semi-circular block 202e. A first clamping plate 202b is disposed on the connecting ring 202a and fixed to the edge of the connecting ring 202a. A first locking block 202c is fixed on the connecting ring 202a. 2c is fixed to the side and fixedly connected to the first clamping plate 202b. At the same time, the first clamping block 202c is also fixed to the edge of the connecting ring 202a. The first clamping block 202c is arranged in a ring with two of them on the connecting ring 202a. The second clamping plate 202d is fixed on the connecting ring 202a. The second clamping plate 202d is fixed on the connecting ring 202a. The semi-circular block 202e is set on the connecting ring 202a and is fixedly connected to the inner wall of the connecting ring 202a.

[0039] Specifically, the clamping assembly 203 includes a rectangular groove 203a disposed on the first clamping plate 202b, the rectangular groove 203a being formed on the inner wall of the first clamping plate 202b, a plurality of toothed blocks 203b disposed on the rectangular groove 203a, the plurality of toothed blocks 203b being fixed inside the rectangular groove 203a, and a protruding plate 203c disposed on the first clamping plate 202b, the protruding plate 203c being fixed to the top of the first clamping plate 202b.

[0040] Furthermore, the docking assembly 205 includes a docking pipe 205a, which is fixedly connected to the outer surface of the mixing tank 204; a third clamping plate 205b disposed on the docking pipe 205a and fixed to the inner wall of the mixing tank 204; a second clamping block 205c fixed on the docking pipe 205a and fixedly connected to the third clamping plate 205b; and a fixing member 205d disposed on the second clamping block 205c and fixedly connected to the inside of the second clamping block 205c.

[0041] The rest of the structure is the same as in Example 1.

[0042] Operating procedure: When sealing the water inlet, the connecting ring 202a will be inside the sliding groove 201b. When it is necessary to fix the discharge pipe 103h to the mixing tank 204, slide the connecting ring 202a to the connection point between the sliding groove 201b and the rotating groove 201c, then rotate the connecting ring 202a. This causes the semi-circular block 202e on the inner wall of the connecting ring 202a to slide into the rotating groove 201c. At this time, the semi-circular block 202e will contact the transition surface 201d-2, then the semi-circular block 202e will fit against the contact surface 201d-3, and finally the semi-circular block 202e will be stuck in the groove. Inside hole 201d-5, connecting ring 202a will be fixed at the end of connecting pipe 201. Then, connecting ring 202a is inserted into connecting pipe 205a. The docking component 205 on connecting pipe 205a will limit connecting ring 202a, thereby fixing connecting pipe 201 to mixing tank 204. The mixture in discharge pipe 103h will flow into mixing tank 204. At this time, there is no need to cancel the power of absorbing material. The mixture in discharge pipe 103h will continue to flow, so the mixture in discharge pipe 103h will not condense, causing discharge pipe 103h to be blocked.

[0043] Example 3, referring to Figures 7 to 10 This is the third embodiment of the present invention. Unlike the previous embodiment, the second locking block 205c includes a block body 205c-1. The block body 205c-1 is provided with a mounting groove 205c-2, which is opened on the side of the second locking block 205c. The block body 205c-1 is provided with a slope 205c-3, which is disposed on one side of the mounting groove 205c-2. The slope 205c-3 allows the first locking plate 202b to fit better with the first locking block 202c, and the first locking block 202c is connected to the third locking plate 205b.

[0044] Specifically, the fastener 205d includes a fixed shaft 205d-1, which is fixedly connected to the mounting groove 205c-2. The fixed shaft 205d-1 has a through hole, and a rotating shaft is connected to the through hole. A rotating block 205d-2 is connected to the fixed shaft 205d-1. One side of the rotating block 205d-2 is U-shaped, and the U-shaped end of the rotating block 205d-2 is rotatably connected to the rotating shaft. A trapezoidal groove 205d-3 is formed on the side of the rotating block 205d-2, and an arc surface 205d-4 is connected to the trapezoidal groove 205d-3. The arc surface 205d-4 is connected to one side of the trapezoidal groove 205d-3, and the arc surface 205d-4 allows the toothed block 203b to be more smoothly engaged in the trapezoidal groove 205d-3.

[0045] Furthermore, the unlocking component 206 includes an unlocking rod 206a, one end of which is fixedly connected to the side of the rotating block 205d-2. The connecting tube 205a has a circular hole, allowing the unlocking rod 206a to move up and down within the circle. A disc 206b is mounted on the unlocking rod 206a and fixed thereon. The disc 206b limits the position of the return spring 206c. The return spring 206c, also mounted on the unlocking rod 206a, is sleeved on the unlocking rod 206a. The return spring 206c increases the clamping force of the rotating block 205d-2 on the toothed block 203b, thus more firmly securing the connecting ring 202a within the connecting tube 205a.

[0046] The rest of the structure is the same as in Example 2.

[0047] Operating procedure: After the connecting ring 202a is inserted into the connecting pipe 205a, rotating the connecting pipe 201 causes the first clamping plate 202b and the second clamping plate 202d on the connecting ring 202a to rotate onto the second clamping block 205c. At this time, the second clamping block 205c will fit against the inner surface of the protrusion and will be locked in the groove of the first clamping plate 202b and the second clamping plate 202d. At the same time, the third clamping plate 205b on the mixing tank 204 will be locked onto the first clamping block 202c on the connecting ring 202a. The rotating block 205d-2 on the second clamping block 205c will be squeezed by the toothed block 203b when the connecting pipe 201 rotates, causing it to rotate. Block 205d-2 rotates on the rotating shaft. When it rotates, it compresses the return spring 206c, causing the unlocking rod 206a to move in the circular hole. At this time, the toothed block 203b will pass through the arc surface 205d-4 and be opened in the trapezoidal groove 205d-3, thereby locking the connecting ring 202a in the connecting pipe 205a. The mixture from the discharge pipe 103h will then enter the mixing tank 204. When it is necessary to remove the discharge pipe 103h from the connecting pipe 205a, simply pull the unlocking rod 206a. The unlocking rod 206a will drive the rotating block to rotate, at which time the toothed block 203b will move out from the trapezoidal groove 205d-3, thereby removing the discharge pipe 103h from the connecting pipe 205a.
