Technical Field

[0001] The utility model relates to the technical field of anti-seepage wall construction, in particular to an anti-seepage wall pouring trough support structure. Background Art

[0002] The anti-seepage wall is an underground continuous anti-seepage structure that plays a very important role in ensuring the seepage stability of loose permeable foundations and the safety of dams and gates. It is not only used in dams, cofferdams, sluices and dikes in water conservancy and hydropower projects, but is also widely used in large-scale mining foundation pit projects, various tailings dams and industrial waste dumps, and municipal engineering.

[0003] Before pouring concrete into the anti-seepage wall grouting trough, there are ground construction workers walking and mechanical equipment working near the anti-seepage wall grouting trough, which can easily affect the grouting trough near the ground slot, causing the grouting slot to collapse and a large amount of soil to fall into the grouting trough, seriously affecting the quality of the anti-seepage wall concrete construction, thereby reducing the concrete strength and affecting the safety and stability of the anti-seepage wall.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 In this embodiment, a support structure for an anti-seepage wall grouting trough includes a foundation 1. Two ground anchor rods 2 are fixed on the top of the foundation 1. The ground anchor rods 2 are used to fix the whole. A support frame 3 is fixed on the top of the two ground anchor rods 2. A connecting rod 4 that penetrates into the interior of the foundation 1 is fixed on the bottom of the support frame 3. The outer surface of the connecting rod 4 is rotatably connected to a transmission assembly.

[0023] Furthermore, the internal rotation of the connecting rod 4 is connected to the rotating rod 8. A through hole is provided inside the connecting rod 4. A fixed bearing is fixed in the hole of the through hole. The inside of the fixed bearing is fixed to the rotating rod 8. The fixed bearing makes the rotation of the rotating rod 8 more stable. The transmission assembly is fixed to the rotating rod 8. The transmission assembly includes a control block 5 rotatably connected to the connecting rod 4. A positioning block is fixed to the inner cavity of the control block 5. A positioning groove is provided inside the connecting rod 4 for sliding connection with the positioning block. Both the positioning block and the positioning groove are annular. The rotation of the control block 5 can be made more stable by providing the positioning block and the positioning groove. A handle is fixed on the left side of the control block 5. The outer surface of the handle is covered with a sponge pad. The provided handle makes it more labor-saving to push the control block 5 to rotate.

[0024] In addition, a driving gear 6 is fixed to the bottom of the control block 5, and two driven gears 7 are engaged with the bottom of the driving gear 6. The driven gear 7 is fixed to the rotating rod 8, and the transmission assembly is used to push the rotating rod 8 to rotate. The left and right sides of the rotating rod 8 are threadedly connected with a push rod 9, and a threaded strip is fixed to the outer surface of the rotating rod 8. A threaded hole that matches the threaded strip is opened inside the push rod 9. Because the push rod 9 is restricted in rotation by the support plate 11, when the rotating rod 8 rotates, the push rod 9 will move due to the extrusion of the thread. A fixing assembly 10 is provided inside the push rod 9, and a support plate 11 is fixed on the opposite side of the two fixing assemblies 10. The fixing assembly 10 is used to fix the support plate 11, and the support plate 11 is in contact with the foundation 1, so that the foundation 1 restricts the rotation of the support plate 11.

[0025] In general, the support plate 11 is in contact with the ground of the foundation 1, so that the support plate 11 cannot rotate with the push rod 9, thereby limiting the rotation of the push rod 9, so that when the rotating rod 8 rotates, it pushes the support plate 11 to move, supporting the support plate 11 on the foundation 1, effectively improving the stability of the foundation 1.

[0026] See also Figure 2-3 , the fixing assembly 10 in this embodiment includes a connecting block 1001, a fixing block 1002, a positioning plate 1003 and a return spring 1004, the connecting block 1001 is fixed to the support plate 11, the interior of the push rod 9 is slidably connected to the fixing block 1002 plugged into the connecting block 1001, and sliding blocks are fixed on both sides of the fixed block 1002, and a sliding groove is provided inside the push rod 9 for sliding connection with the sliding block. The outer surface of the fixing block 1002 is fixed to the positioning plate 1003, and the positioning plate 1003 and the push rod 9 are fixed with the return spring 1004. The reset spring 1004 is set to prevent the fixing block 1002 from sliding into the interior of the push rod 9, thereby ensuring the stability of the connection between the fixing block 1002 and the connecting block 1001, and a rubber pad is fixed on the top of the fixing block 1002, and inclined surfaces are provided on both sides of the fixing block 1002.

[0027] In general, when the support plate 11 needs to be disassembled, by pressing the fixing block 1002, the fixing block 1002 can be moved a certain distance toward the inside of the push rod 9, and the inclined surface on the fixing block 1002 can be moved to the inner cavity of the connecting block 1001. At this time, pushing the connecting block 1001 can produce a certain amount of extrusion on the inclined surface, so that the fixing block 1002 is further moved toward the inside of the push rod 9 due to the extrusion, thereby completing the disassembly of the fixing block 1002 and the connecting block 1001.

[0028] The working principle of the above embodiment is:

[0029] After fixing the ground anchor rod 2 to the foundation 1, fix the support frame 3 to the connecting rod 4 with bolts. At this time, by pushing the control block 5, the driving gear 6 can be rotated, and the driving gear 6 is engaged with the driven gear 7, so that the driven gear 7 drives the rotating rod 8 to rotate. When the rotating rod 8 rotates, the support plate 11 is in contact with the ground of the foundation 1, so that the foundation 1 limits the support plate 11 from rotating with the push rod 9, and the push rod 9 moves on the outer surface of the rotating rod 8 due to the extrusion of the thread, supporting the support plate 11 on the foundation 1, effectively improving the foundation. 1, and when the support plate 11 needs to be replaced, the fixing block 1002 can be moved to the inside of the push rod 9 by pressing the fixing block 1002. At this time, the support plate 11 is pushed hard to make the connecting block 1001 contact with the inclined surface on the fixing block 1002, and then the fixing block 1002 is further moved toward the inside of the push rod 9 due to the squeezing of the inclined surface, thereby completing the disassembly of the support plate 11, and then the support plates 11 of different sizes can be replaced as needed. The overall structure is simple, which effectively improves the overall stability, making the overall structure more practical.
