Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water-stopping device for cracks in bare rock. Background Technology
[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. In projects such as bridge pile foundations, dam foundations, tunnel excavation, slope protection and deep foundation pit excavation, it is common to encounter geological conditions with exposed bedrock.
[0003] Due to long-term geological tectonic movements, bedrock contains numerous randomly distributed fissures, joints, or solution fissures. When excavation reaches below the groundwater level, pressurized fissure water will gush out along these channels, causing fissure leakage or water inrush. This necessitates the use of water-stopping devices. However, some existing water-stopping devices have fixed pipe lengths. After the pipes are pre-buried, they are connected to external grouting pumps and pressure source equipment. When the position of the pipes needs to be adjusted, workers must completely remove the device, cut or replace the pipes, and reinstall them, thus reducing construction efficiency.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example 1: Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a water-stopping device for cracks in bare rock, including a first connecting pipe 1, a second connecting pipe 2 provided at one end of the first connecting pipe 1, a sealing bag 3 provided on the outside of the second connecting pipe 2, an mounting plate 4 slidably connected to the outside of the first connecting pipe 1, and an adjusting component 5 provided at the end of the second connecting pipe 2 away from the first connecting pipe 1.
[0026] With the help of the mounting plate 4, the device can be stably connected to the rock wall, thus enabling the device to work normally. At the same time, with the help of multiple first connecting pipes 1 and multiple second connecting pipes 2, it can adapt to the rock fissures of different depths.
[0027] The adjustment assembly 5 includes a central conduit 506 located at the end of the second connecting pipe 2 away from the first connecting pipe 1. An adjustment rod 501 is threadedly connected inside the central conduit 506. A positioning plate 502 is fixedly connected to one end of the adjustment rod 501. A fixing claw 503 is fixedly connected to one side of the positioning plate 502. A connector 504 is fixedly connected to one end of both the first connecting pipe 1 and the second connecting pipe 2. A connecting pipe 505 is fixedly connected to the other end of the first connecting pipe 1.
[0028] Rotating the adjusting rod 501 causes the interior of the central guide tube 506 to slide into contact with the inner wall of the second connecting tube 2. The second connecting tube 2 has a third sealing ring inside, allowing adjustment of the actual usable length of the central guide tube 506 to accommodate fissures of varying depths. Simultaneously, the multiple fixing claws 503 ensure a stable connection between the adjusting rod 501 and the rock wall. Furthermore, the adjusting rod 501 and the central guide tube 506 are self-locked by their threads. The number of first connecting tubes 1 and second connecting tubes 2 can be adjusted to stop water flow in different fissures. The length of the second connecting tube 2 can be customized, thereby adjusting the position of the first sealing disc 6.
[0029] Example 2: Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0030] Specifically, a first sealing disc 6 is fixedly connected to the outside of the second connecting pipe 2, and a first sealing ring 7 is provided inside the first sealing disc 6. The inner wall of the first sealing ring 7 is slidably connected to the outside of the second connecting pipe 2.
[0031] The first sealing disc 6 prevents slurry from leaking through the gaps between the pipes.
[0032] Specifically, the first sealing disc 6 is provided with a second sealing ring 8 inside, and the number of the second sealing ring 8 is set to two.
[0033] Under the action of the two second sealing rings 8, the positions where the grouting pipe 15 and the return grout pipe 16 contact the first sealing disc 6 can be sealed.
[0034] Specifically, a second sealing disc 9 is fixedly connected to the outer side of the first sealing disc 6, and the outer side of the second sealing disc 9 is fixedly connected to the inside of the sealing bag 3.
[0035] With the help of the second sealing disc 9, it is easy for staff to place and position the sealing bag 3, so that the sealing bag 3 can be placed in the designated position.
[0036] Specifically, a third sealing disc 10 is provided on one side of the second sealing disc 9, and a first positioning bolt 11 is threadedly connected to the inside of the third sealing disc 10.
[0037] Under the action of the third sealing disc 10, the gap between the second sealing disc 9 and the first sealing disc 6 can be sealed, thereby preventing the slurry from leaking through the gap between the second sealing disc 9 and the first sealing disc 6.
[0038] Specifically, the outer side of the first positioning bolt 11 is threadedly connected to the inner side of the second sealing disc 9.
[0039] By setting the first positioning bolt 11, the second sealing disc 9 and the third sealing disc 10 can be positioned and locked under the action of the first positioning bolt 11.
[0040] Specifically, one side of the sealed bag 3 is connected to a side tube 12.
[0041] With the help of the side tube 12, it is easy for the staff to adjust the expansion degree of the sealing bag 3, thereby sealing the cracks in the bare rock.
[0042] Example 3: Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0043] Specifically, the mounting plate 4 has a second positioning bolt 13 connected to its internal thread, and the number of the second positioning bolts 13 is set to four.
[0044] The second positioning bolt 13 can fix the device to the rock wall, thus making the device stable.
[0045] Specifically, the central conduit 506 has a through hole 14 inside.
[0046] With the help of multiple through holes 14, it is convenient for workers to carry out grouting operations through the central guide tube 506. At the same time, a protective tube is fixedly connected inside the central guide tube 506. The protective tube is used to protect the adjusting rod 501 and prevent the grout from affecting the operation of the adjusting rod 501. Meanwhile, one end of the protective tube is fixedly connected to the inner wall of the end of the central guide tube 506 near the positioning plate 502.
[0047] Specifically, a grouting pipe 15 and a grout return pipe 16 are respectively provided on the outer side of the central conduit 506, and the outer sides of the grouting pipe 15 and the grout return pipe 16 are slidably connected to the inside of the second sealing disc 9.
[0048] Under the action of the second sealing disc 9, the outside of the grouting pipe 15 and the return grouting pipe 16 can be sealed to prevent grout from leaking through the gap between the grouting pipe 15 and the return grouting pipe 16 and the second sealing disc 9.
[0049] When using this device for sealing water in exposed rock fissures, the operator first measures the depth of the fissure, then determines the number of the first connecting pipe 1 and the second connecting pipe 2, and connects the first connecting pipe 1, the second connecting pipe 2, and the central guide pipe 506. With the help of the connector 504 and the connecting pipe 505, the first connecting pipe 1, the second connecting pipe 2, and the central guide pipe 506 are stably connected. The central guide pipe 506 is then placed inside the fissure, and the sealing discs are installed and connected so that each sealing ring can be placed in the designated position. The operator then rotates the adjusting rod 501, which moves inside the central guide pipe 506, thereby moving the positioning plate 502 to the designated position. Simultaneously, with the help of multiple fixing claws 503, the positioning plate 502 can be positioned in the uneven area of the fissure, facilitating the operator's adjustment of the position of the central guide pipe 506 and improving the efficiency of the water sealing operation.
