Description

Technical Field

[0001] This utility model relates to a piping sealing device. Background Technology

[0002] Earth-rock dams and earth-rock retaining walls offer numerous advantages, but piping is a common problem due to factors such as approaching their design lifespan or geological hazards. When piping occurs, the water surface churns, and as the upstream water level rises and the duration of the churn lengthens, the situation worsens. Large amounts of gushing water and sand cause damage to the soil framework of the dam and sluice gate foundations, enlarge the channels, and erode the foundation soil, leading to structural collapse and resulting in accidents such as dam breaches, dam failures, and sluice gate failures.

[0003] Currently, when piping occurs, pressure-reducing cofferdams or reverse-filter cofferdams are generally used for emergency response. Traditional pressure-reducing cofferdams are constructed by quickly building a cofferdam around the piping point using sandbags to raise the water level inside the cofferdam, reduce the head difference, and lower the seepage pressure, thus stabilizing the piping situation. Reverse-filter cofferdams, on the other hand, are built on top of pressure-reducing cofferdams, with filter material filled inside to prevent the underlying sand layer from being eroded and exacerbating the situation. However, traditional cofferdams, constructed using sandbags, are labor-intensive and resource-intensive. They can only function after the entire cofferdam is built and the walls are leak-proof, resulting in long construction times and low efficiency, which cannot meet the urgent needs of flood control and emergency response. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a piping sealing device. This device can block piping in an emergency by using sealing components and filter components, and can retain mud and sand inside, reduce mud and sand loss, and thus avoid the hollowing out of the sand layer and avoid more dangerous accidents.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a piping blockage device, including a filter element, which surrounds the piping point and has a stabilizing element around it. The stabilizing element is used to stabilize the position of the filter element. A blocking element is connected to the filter element through a screw rod. The screw rod is used to adjust the depth of the blocking element embedded in the piping point. The blocking element is used to block the piping point and is permeable to water and sand.

[0006] Furthermore, the sealing component includes a conical tip, the upper end of which is provided with an extension and a spreading portion. The spreading portion is disposed within the extension and there is a gap between the inner wall of the extension and the outer wall of the spreading portion. A water-permeable component is disposed within the gap, and the upper end of the water-permeable component surrounds the periphery of the spreading portion. When the spreading portion is spread open, the water-permeable component expands synchronously.

[0007] Furthermore, the expansion portion includes multiple expansion plates disposed at the upper end of the conical tip, with the multiple expansion plates being circumferentially spaced. Each expansion plate is equipped with an expansion member, which is used to drive the expansion plate to expand circumferentially.

[0008] Furthermore, the inner wall of the expansion plate is inclined and a triangular block extends from the upper end. The triangular block surrounds and forms a frustum-shaped cavity. The expansion member is set in the frustum-shaped cavity. The expansion member includes a top support block. The upper end of the top support block is provided with an upper pull rod. Both the upper pull rod and the top support block are provided with through holes at their centers. The upper end of the upper pull rod is provided with a rotating nut.

The circumferential expansion of the extension frame is achieved by rotating and moving the moving tube downward, thereby expanding the expansion plate.

[0011] Furthermore, the water-permeable component includes an elastic reverse filter cloth or an elastic water-permeable membrane in the shape of an inverted frustum, and the water-permeable component is clamped around the periphery of the expansion part by an elastic ring;

[0012] Alternatively, the permeable component may include multiple filter screens surrounding the periphery of the support portion, with one side wall of the filter screen slidably connected to the outer wall of the support plate, and the other side wall slidably connected to the outer wall of the adjacent support plate, and the inner wall of the filter screen is covered with reverse filter cloth or permeable membrane.

[0014] Furthermore, the stabilizing component includes multiple vertical protrusions on the side wall of the tube body, and a cavity inside each vertical protrusion.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] For reference Figure 1 , Figure 2 As shown, this application provides a sealing device to solve the piping problem. The sealing device includes a filter element 1, which surrounds the piping location and has a stabilizing element 2 around it. The stabilizing element 2 is used to stabilize the position of the filter element 1. A sealing element 3 is connected to the filter element 1 through a screw rod 4. The screw rod 4 is used to adjust the depth of the sealing element 3 embedded in the piping opening. The sealing element 3 is used to seal the piping opening and can also be permeable to water and block sand, minimizing the outflow of sand layers and preventing damage to the foundation soil skeleton of dams and sluice gates, expansion of the channels, scouring of the foundation soil, and collapse of structures, resulting in accidents such as dam breaches, dam collapses, and sluice gate failures.

[0026] Specifically, the filter element 1 includes a pipe 1-1, an annular filter layer 1-2 inside the pipe 1-1, a stepped surface on the inner wall of the annular filter layer 1-2, a circular filter layer 1-3 snapped onto the stepped surface, a drainage hole on the outer wall of the pipe 1-1, a connecting frame 1-4 at the upper end of the pipe 1-1, a fixing nut fixed at the center of the connecting frame 1-4, and a screw 4 connected to the fixing nut. The downward or upward movement of the sealing element 3 is achieved by rotating the screw 4, thereby sealing the piping outlet.

[0027] like Figure 1 , Figure 4 As shown, the stabilizer 2 is located around the pipe fitting 1-1 and includes multiple vertical protrusions 2-1 on the side wall of the pipe fitting 1-1. Each vertical protrusion 2-1 has a cavity inside, and multiple insertion holes 2-2 are vertically distributed on the side wall of the vertical protrusion 2-1. An elastically connected insertion rod 2-3 is provided in the cavity. The insertion rod 2-3 has a horizontal through groove and a vertical groove. A telescopic locking block 2-4 is spring-connected in the horizontal through groove. The end face of the telescopic locking block 2-4 is inclined. A rotating knob 2-5 is threaded in the vertical groove. The end of the rotating knob 2-5 fits against the inclined surface of the telescopic locking block 2-4. When the rotating knob 2-5 is rotated downward, it causes the telescopic locking block 2-4 to extend out of the horizontal through groove and engage with the insertion hole 2-2, thereby limiting the depth of the insertion rod 2-3 into the soil and stabilizing the pipe fitting 1-1 to remain vertical.

[0028] like Figure 1 As shown, the sealing component 3 includes a conical tip 3-1. The upper end of the conical tip 3-1 has an extension 3-2 and a spreading portion 3-3. The spreading portion 3-3 is disposed within the extension 3-2, and a gap 3-4 exists between the inner wall of the extension 3-2 and the outer wall of the spreading portion 3-3. A water-permeable component 5 is disposed within the gap 3-4, with its upper end surrounding the spreading portion 3-3. The spreading portion 3-3 includes multiple spreading plates 6 disposed at the upper end of the conical tip 3-1, with the plates 6 circumferentially spaced. The spreading plates 6 have a certain elasticity, allowing them to deform synchronously when expanded by the expansion component 7. The expansion component 7 drives the spreading plates 6 to expand circumferentially. Figure 1 , Figure 2As shown, in the first embodiment, the inner wall of the expansion plate 6 is inclined, and a triangular block 6-1 extends from the upper end. The triangular block 6-1 encloses and forms a frustum-shaped cavity. The expansion member 7 is disposed in the frustum-shaped cavity. The expansion member 7 includes a top support block 8. The outer wall of the top support block 8 is provided with multiple filter holes 8-1, and the inner wall of the top support block 8 is provided with filter packing material 8-2 to further enhance the filtration function. An upper pull rod 9 is rotatably provided at the upper end of the top support block 8. Both the upper pull rod 9 and the top support block 8 are provided with through holes in the center, through which the lead screw 4 passes and is fixedly connected to the conical tip 3-1. The upper end of the upper pull rod 9 is equipped with a rotating nut, which is connected to the screw rod 4. When one hand fixes the screw rod 4 and does not rotate, and the other hand rotates the rotating nut, the rotating nut moves the upper pull rod 9 upward, and the top support block 8 expands outward against the expansion plate 6. The expansion plate 6 expands outward in a circumferential direction, and at the same time, it expands the permeable part 5 in a circumferential direction, so as to adapt to different piping openings. Moreover, the circumferential expansion force on the piping opening makes the soil around the piping opening squeezed and compacted, better sealing the piping opening.

[0029] like Figure 1 The permeable component 5 shown includes an elastic reverse filter cloth or elastic permeable membrane in the shape of an inverted frustum. The elastic reverse filter cloth or elastic permeable membrane is clamped around the outer periphery of the spreader cloth by an elastic ring 13. When the expander 7 expands the spreader plate 6, the elastic reverse filter cloth or elastic permeable membrane is simultaneously subjected to the expansion force, which makes the expansion area of ​​the elastic reverse filter cloth or elastic permeable membrane larger.

[0030] Or such as Figure 3 As shown, a permeable component 5 with a different structure is used. The permeable component 5 includes multiple filter screen plates 12 surrounding the outer perimeter of the support plate 6. One side wall of the filter screen plate 12 is slidably connected to the outer wall of the support plate 6, and the other side wall is slidably connected to the outer wall of the adjacent support plate 6. When the expansion member 7 expands the support plate 6, the filter screen plate 12 also expands accordingly. The filter screen plate 12 is lined with a reverse filter cloth or a permeable membrane to further enhance the permeable sand screening function.

[0031] For reference Figure 3 , Figure 5 As shown, this application also provides a second embodiment, which is basically the same as the first embodiment described above, except that: an extension frame 10 is provided on the expansion plate 6, one end of the extension frame 10 is hinged to the expansion plate 6, and the other end is hinged to the outer wall of the moving tube 11. A rotating nut is provided at the upper end of the moving tube 11 and the rotating nut is connected to the lead screw 4. The circumferential expansion of the extension frame 10 is achieved by rotating and moving the moving tube 11 downward, thereby expanding the expansion plate 6.

[0032] Specifically, the expansion plate 6 is provided with an extension frame 10. One end of the extension frame 10 is hinged to the expansion plate 6, and the other end is hinged to the rotating ring on the outer wall of the moving tube 11. The rotating ring is movably connected to the moving tube 11. The upper end of the moving tube is provided with a rotating nut and the rotating nut is connected to the lead screw 4. With one hand fixing the lead screw 4 so that it does not rotate, the other hand rotates the moving tube 11. The moving tube 11 moves downward and will support the expansion plate 6 outward through the extension frame 10. At the same time as the outward support, the permeable part 5 expands synchronously.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
