Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a grouting pipe device for preventing de-airing in dam filling. Background Art
[0002] In water conservancy project construction, dams are important water conservancy facilities, and their stability and safety are of paramount importance. However, during the dam filling process, especially after the settlement period, gaps often occur between the extruded sidewalls and the cushion material. This not only affects the overall stability of the dam but can also lead to a series of safety hazards.
[0003] After searching, patent publication number CN218291961U discloses a grouting pipe system for dam filling to prevent debulking, including cushion material, extruded side walls, and grouting pipes. The extruded side walls are laid on the slope of the cushion material, and several grouting pipes are arranged along the height of the inner wall root of the extruded side walls. Each grouting pipe is laid horizontally, and a number of grouting holes are set on the side wall of each grouting pipe along the laying direction. The two ends of each grouting pipe extend out of the extruded side wall, and the two end openings of each grouting pipe serve as grouting inlets. This solution can solve the debulking phenomenon that occurs between the extruded side wall and the cushion material after the dam settlement period. Since the debulking is usually fault debulking, the laying direction of the grouting pipe is more compatible with the debulking space, and the grouting effect is better.
[0004] This solution also has the following problems: by injecting slurry into the grouting pipe, the slurry enters the hollow area inside the dam through the grouting holes. However, since the grouting holes are located on the grouting pipe and inside the dam, when the grouting holes are blocked by the slurry, grouting cannot be carried out. When blocked, it is inconvenient to clear the grouting holes, so there are certain disadvantages. Utility Model Content

[0025] Reference Figures 1 to 7 In an embodiment of the present invention, a grouting pipe device for preventing de-airing in dam filling is provided, comprising: a grouting pipe 1, a plurality of grouting holes 101 are opened at equal intervals on the outer ring surface of the grouting pipe 1, a turning handle 2 is installed at one end of the outer ring top of the grouting pipe 1, a first feeding pipe 3 is installed at one end of the outer ring bottom of the grouting pipe 1 and away from the first feeding pipe 3, a second feeding pipe 4 is installed between the inner side walls of the grouting pipe 1, a fixed plate 6 is installed on the outer ring surface of the rotating rod 5, four groups of limiting columns 7 are installed at equal intervals on the outer ring surface of the fixed plate 6, a movable column 8 is installed on the outer ring surface of the fixed plate 6 and between the two limiting columns 7, and an extrusion head 9 is installed at the end of the movable column 8 away from the fixed plate 6.
[0026] Reference Figures 1 to 4One end of the rotating rod 5 passes through the outside of the grouting pipe 1 and is connected to the turning handle 2, and the end of the rotating rod 5 away from the turning handle 2 is rotatably connected to the other side wall inside the grouting pipe 1, the outer ring surface of the rotating rod 5 is rotatably connected to the inside of the fixed plate 6, and the end of the limiting column 7 away from the fixed plate 6 is connected to the inner wall of the grouting pipe 1.
[0027] The above solution is adopted: by driving the turning handle 2 to drive the rotating rod 5 to rotate, the rotating rod 5 rotates synchronously inside the fixed plate 6, and by providing multiple groups of limit columns 7, the stability of the fixed plate 6 inside the grouting pipe 1 is increased.
[0028] Reference Figures 1 to 4 A rotating block 10 is installed on one side wall of the inner side of the fixed disk 6, and arc-shaped connecting blocks 11 are installed at the four corners of the outer side of the rotating block 10. The outside of the rotating block 10 and one end of the four arc-shaped connecting blocks 11 are all rotatably connected, and the outer ring surface of the rotating rod 5 is fixedly connected to the inside of the rotating block 10.
[0029] The above solution is adopted: the rotating rod 5 rotates to synchronously drive the rotating blocks 10 inside the multiple fixed disks 6 to rotate, and when the rotating blocks 10 rotate, the four groups of arc-shaped connecting blocks 11 are synchronously driven to rotate.
[0030] Reference Figures 1 to 5 Four sets of T-shaped slide rails 12 are installed on one side wall of the inner side of the fixed disk 6 with the rotating block 10 as the axis. Slide blocks 13 are installed on the outside of the T-shaped slide rails 12. A fixed block 14 is installed on one end of the outer side of the slider 13. The arc-shaped connecting block 11 is rotatably connected between the end away from the rotating block 10 and the outside of the fixed block 14.
[0031] With the above solution, when the rotating block 10 rotates, the slider 13 is driven to slide outside the T-shaped slide rail 12 through the arc-shaped connecting block 11, and a T-shaped slot is provided inside the slider 13 to increase the stability of sliding outside the T-shaped slide rail 12.
[0032] Reference Figures 1 to 5 A fixed column 15 is installed on the outside of the slider 13, and the end of the movable column 8 away from the extrusion head 9 passes through the interior of the fixed plate 6 and is connected to the fixed column 15. The number of the extrusion head 9 is adapted to the number of the grouting holes 101, and the extrusion head 9 can be moved through the movable column 8 to access the interior of the grouting hole 101.
[0033] The above solution is adopted: when the slider 13 slides on the outside of the T-shaped slide rail 12, it simultaneously drives the movable column 8 to move. When the movable column 8 moves, it drives the extrusion head 9 to access the inside of the grouting hole 101, and pushes out the slurry blocked inside the grouting hole 101, so as to facilitate continuous grouting and improve the grouting efficiency.
[0034] Reference Figures 6 and 7A sealing cover 16 is provided at the opening of the first feed pipe 3 and the second feed pipe 4, and limiting holes 1601 are symmetrically provided at both ends of the outside of the sealing cover 16. Telescopic rods 17 are symmetrically installed at both ends of the outside of the first feed pipe 3 and the second feed pipe 4. A return spring 18 is installed on the outer ring surface of the telescopic rod 17, and a movable block 19 is installed at one end of the telescopic rod 17. A limiting rod 20 is installed on the outside of the movable block 19 away from one end of the telescopic rod 17 and inside the limiting hole 1601.
[0035] The above solution is adopted: by pulling outward the two movable blocks 19, the movable blocks 19 move outward and simultaneously stretch the telescopic rod 17 and the return spring 18, and one end of the limit rod 20 is away from the limit hole 1601, so that the sealing cover 16 can be removed. When installing, the two movable blocks 19 are pulled outward and the sealing cover 16 is installed on the top of the first feeding pipe 3, and then the two movable blocks 19 are released. The restriction of the return spring 18 is lifted and the limit rod 20 is driven to enter the inside of the limit hole 1601, thereby fixing the sealing cover 16. Disassembly and assembly are convenient, and the provision of the sealing cover 16 prevents debris from entering the interior of the grouting pipe 1 during construction, thereby affecting the later grouting.
[0036] The working principle of the present invention is as follows: during the use of the device, the device is installed on the cushion material inside the dam. After the settlement of the dam is stabilized, a gap will be formed between the squeezed side wall and the filled dam body. By pulling the two movable blocks 19 outward, the telescopic rod 17 and the return spring 18 are stretched synchronously when the movable block 19 moves outward, and one end of the limit rod 20 is away from the limit hole 1601, the sealing cover 16 can be removed, and grouting can be simultaneously performed into the interior of the grouting pipe 1 through the first feed pipe 3 and the second feed pipe 4. If the grouting hole 101 is blocked during grouting, the rotating handle 2 is driven to rotate the rotating rod 5, and the rotating rod 5 is synchronously rotated inside the fixed plate 6. The rotation of the rotating rod 5 synchronously drives the rotating rods inside the multiple fixed plates 6. The movable block 10 rotates, and when the rotating block 10 rotates, it synchronously drives the four groups of arc-shaped connecting blocks 11 to rotate. When the rotating block 10 rotates, it drives the slider 13 to slide on the outside of the T-shaped slide rail 12 through the arc-shaped connecting block 11, and the slider 13 is provided with a T-shaped slot inside to increase the stability of sliding on the outside of the T-shaped slide rail 12. When the slider 13 slides on the outside of the T-shaped slide rail 12, it synchronously drives the movable column 8 to move. When the movable column 8 moves, it drives the extrusion head 9 to access the inside of the grouting hole 101, and pushes out the slurry blocked inside the grouting hole 101. Then, reversing the handle 2 can drive the extrusion head 9 to reset away from the grouting hole 101, so as to facilitate continuous grouting, and the grouting efficiency is higher, which avoids grouting failure due to blockage inside the grouting hole 101.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
