[0002] The intelligent grouting pipeline for the toe slab of a rockfill dam is a special type of grouting pipeline used for intelligent grouting construction of the toe slab. Because toe slab grouting needs to withstand high pressure, the pipeline must have sufficient strength and pressure resistance to prevent bursting or deformation. Since the grouting material usually contains acidic or alkaline substances, the pipeline must have good corrosion resistance to ensure long-term stability and reliability. The pipeline should be lightweight for easy handling and installation. Simultaneously, pipeline connections should be convenient and quick to accelerate construction progress. The pipeline should have good leak-proof performance to prevent grout leakage from polluting the surrounding environment.

[0003] Grouting pipes are typically sealed and secured to grouting machines and to other grouting pipes using flanges, sealing rings, bolts, and nuts. However, if the bolts and nuts are not tightened properly, or if they loosen during use, gaps can easily appear at the connections, leading to grout leakage and environmental pollution. Solving this problem is a pressing issue that needs to be addressed. Utility Model Content

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a grouting pipe connection mechanism, including a flange 1, on which a sealing ring is provided, and the flange 1 is connected to the pipe and the grouting machine; a sealing component 2, which is disposed between two sets of flanges 1, and the sealing component 2 is elastic; when the fastening state of the flange 1 changes during use, causing a gap to be generated between the flange 1 and the sealing ring, the sealing component 2 can fill the gap and maintain the sealing state of the flange 1.

[0032] In practice, the pipe is first fixed to the grouting machine and the flange 1 on the pipe with bolts and nuts. After fixing, the sealing component 2 is pressed into the gap formed by the two flanges 1 and sealed by its reset. It is then fixed by the fixing component 3. If the bolts and nuts are not tightened properly or become loose during use, the sealing component 2 can seal the gap at the connection, thereby avoiding the problem of grout leakage and environmental pollution. At the same time, it avoids the problem of low construction efficiency caused by the need for remedial measures when grout leaks.

[0033] It should be noted that, in the prior art, a sealing ring can also be provided on the outer wall of the sealing component 2 to improve the sealing effect.

[0034] Example 2

[0035] Based on Example 1, such as Figure 3 As shown, the sealing component 2 includes multiple arc-shaped plates 4, a first arc-shaped movable plate 5 and a second arc-shaped movable plate 6 slidably disposed on the arc-shaped plates 4 along the central axis direction (e.g., only the first arc-shaped movable plate 5 can slide, or only the second arc-shaped movable plate 6 can slide, or both the first arc-shaped movable plate 5 and the second arc-shaped movable plate 6 can slide), a return spring 7 disposed between the first arc-shaped movable plate 5 and the second arc-shaped movable plate 6, and a sealing sleeve 8 sleeved on the first arc-shaped movable plate 5 and the second arc-shaped movable plate 6.

[0036] In practice, when the first arc-shaped moving plate 5 slides and engages with the arc-shaped plate 4, and the second arc-shaped moving plate 6 is fixedly engaged with the arc-shaped plate 4, pressing the first arc-shaped moving plate 5 compresses the return spring 7, reducing the distance between the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6. The first arc-shaped moving plate 5 and the second arc-shaped moving plate 6, which are fitted with sealing sleeves 8, are then inserted into the gap formed by the two flanges 1. After insertion, the return spring 7 resets and presses the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 to press the sealing sleeve 8 into close contact with the flange 1, thereby sealing the gap between the two flanges 1.

[0037] Example 3

[0038] Based on Example 2, such as Figures 3-6 As shown, multiple T-shaped grooves 9 are provided on the inner wall of the arc-shaped plate 4 along the central axis direction; multiple T-shaped blocks 10 that cooperate with the T-shaped grooves 9 are provided on the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 or the first arc-shaped moving plate 5. The T-shaped grooves 9 on the arc-shaped plate 4 facilitate the sliding of the T-shaped blocks 10 on the sliding first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 to press and retract the return spring 7. At the same time, the T-shaped blocks 10 also serve as a limit to ensure the sliding direction of the first arc-shaped moving plate 5 or the second arc-shaped moving plate 6 and prevent the return spring 7 from shifting due to pressing or resetting.

[0039] Example 4

[0040] Based on Example 3, such as Figure 3 and Figure 5As shown, the sealing sleeve 8 includes a first fixed sealing gasket 11 fixedly disposed on the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 on opposite sides of the return spring 7, and an edge elastic rubber gasket 12 and an inner ring elastic rubber gasket 13 connected to the first fixed sealing gasket 11 and fixedly disposed on the ends and inner ring of the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6. The first fixed sealing gasket 11 seals the gap between the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 and the flange 1. The first fixed sealing gasket 11 is fixedly installed on the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6, which drives the edge elastic rubber gasket 12 and the inner ring elastic rubber gasket 13 to expand or contract, so as to facilitate the expansion or contraction of the sealing sleeve 8 to achieve the sealing effect. At the same time, it is convenient for it to be inserted between the two flanges 1. The first fixed sealing gasket 11 can be a rubber gasket, while the edge elastic rubber gasket 12 and the inner ring elastic rubber gasket 13 are preferably rubber gaskets with greater elasticity. The edge elastic rubber gasket 12 and the inner ring elastic rubber gasket 13 are fixedly installed on the ends of the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6 and on the inner ring, in order to increase the force and avoid the problem of the first fixed sealing gasket 11 being easily damaged by the force.

[0041] Example 5

[0042] Based on Example 4, such as Figures 2-6 As shown, the sealing sleeve 8 also includes a second fixed sealing gasket 14 connected to the first fixed sealing gasket 11 and cooperating with the arc-shaped plate 4. The first arc-shaped moving plate 5 and / or the second arc-shaped moving plate 6 are slidably disposed on one side of the arc-shaped plate 4, and the second fixed sealing gasket 14 is movably cooperating with the arc-shaped plate 4. The purpose of setting the second fixed sealing gasket 14 is to increase the sealing area to improve the sealing effect, and the second fixed sealing gasket 14 is movably disposed on the arc-shaped plate 4 to ensure that the first arc-shaped moving plate 5 and / or the second arc-shaped moving plate 6 can slide.

[0043] Example 6

[0044] Based on Example 5, such as Figure 3 As shown, the fixing component 3 includes connecting pieces 15 disposed at both ends of the first arc-shaped moving plate 5 and the second arc-shaped moving plate 6, mounting holes disposed on the connecting pieces 15, and bolts and nuts that cooperate with the mounting holes for fixing.
