Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, specifically to a grouting equipment for filling karst caves during construction. Background Technology

[0002] Grouting for karst cave filling is an effective geological engineering technique mainly used to repair and reinforce karst caves, increasing the stability of geological structures. Grouting involves injecting specific grouting materials into the karst cave through drilling to fill cavities and cracks, thereby reinforcing the karst cave and its surrounding geological body and improving the stability of the geological structure. The grouting materials are typically concrete composed of cement, mortar, polyamide, and other additives, or chemical solutions. These materials have good compressive and bonding strength and can solidify to form a high-strength solidified body, providing support and reinforcement for the karst cave. However, existing grouting heads are not easily adjustable, and the method of adjusting the position of the grouting head inside the karst cave is cumbersome, leading to problems such as uneven grouting, insufficient grouting volume, or excessive grouting, thus affecting the overall effect of karst cave filling grouting. Utility Model Content

[0003] The purpose of this utility model is to provide a grouting device for filling karst caves for construction, so as to solve the problems mentioned in the background art, such as the inconvenience of telescopic adjustment of the existing grouting head, the cumbersome method of adjusting the position of the grouting head inside the karst cave, resulting in uneven grouting, insufficient grouting or excessive grouting, thereby affecting the overall effect of karst cave filling and grouting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for filling karst caves during construction, comprising:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a grouting device for filling karst caves for construction, comprising: a fixed support 1; a grouting pipe 3 slidably disposed inside the fixed support 1; a filling grouting head 4 fixedly connected to one end of the grouting pipe 3, the filling grouting head 4 having multiple grouting through holes 5 equidistantly opened inside; a mounting side plate 2 slidably disposed outside the grouting pipe 3, one side of the mounting side plate 2 being fixedly connected to the fixed support 1; a first outer fixed box 9 fixedly connected to one side of the fixed support 1, the first outer fixed box 9 having an inner sliding plate 7 slidably disposed inside, one side of the inner sliding plate 7 being fixedly connected to a first limiting block 10, the first limiting block 10 being slidably connected to the first outer fixed box 9; a second outer fixed box 14 fixedly connected to one side of the fixed support 1, the second outer fixed box 14 having a second limiting block 15 slidably disposed inside; and limiting slots 13 symmetrically and equidistantly opened outside the grouting pipe 3, the first limiting block 10 and the second limiting block 15 both cooperating with the limiting slots 13.

[0025] It is understood that in this utility model, the limiting bolt 16 is rotated outward, causing the second limiting block 15 to leave the currently fixed limiting slot 13. The mounting side plate 2 is then installed and fixed at the karst cave position of the drilled hole using bolts. The mounting positions of the fixing bracket 1 and the mounting side plate 2 are fixed. The grout inlet pipe 6 is connected to the grouting pump through a pipe. The filling grout enters the grouting pipe 3 through the grout inlet pipe 6, and then enters the filling grouting head 4 through the grouting pipe 3. Grouting is then performed through the grouting through hole 5 opened in the filling grouting head 4. When adjusting the position of the grouting pipe 3 and the filling grouting head 4, when adjusting the insertion position of the grouting pipe 3 in the karst cave, the grouting pipe 3 is directly pushed when it is moved inward. The grouting pipe 3 drives the outer limiting groove 13 to move. The limiting groove 13 pushes against the inclined surface 17 on one side of the first limiting block 10. The inclined surface 17, under force, pushes the first limiting block 10 and the inner sliding plate 7 into the first outer fixing box 9. The first outer fixing box 9 presses the return spring 12. After the grouting pipe 3 enters the appropriate position in the karst cave, the return spring 12 will return to its original position and drive the inner sliding plate 7 into the karst cave. The moving plate 7 and the first limiting block 10 enter the limiting slot 13. Then, the limiting bolt 16 is rotated inward. The limiting bolt 16 drives the second limiting block 15 into the limiting slot 13 on one side, thus restricting and fixing the position of the grouting pipe 3. This fixes the position of the filling grouting head 4 and the grouting through hole 5, completing the grouting of the karst cave through the grouting through hole 5. When the grouting pipe 3, the filling grouting head 4, and the grouting through hole 5 are moved outward for adjustment, the limiting bolt 16 is rotated outward. The limiting bolt 16 drives the second limiting block 15 away from the current position. The limiting slot 13 is fixed, and then the pull block 11 is pulled outward. The pull block 11 drives the pull rod 8, the inner sliding plate 7 and the first limiting block 10 to move outward. The first limiting block 10 leaves the current limiting slot 13, and then the grouting pipe 3 can be pulled outward. The grouting pipe 3 drives the filling grouting head 4 and the grouting through hole 5 to move outward. When the grouting pipe 3 moves, it drives the limiting strip 18 to move synchronously. The limiting strip 18 slides with the fixed bracket 1 and the mounting side plate 2 to limit the adjustment stability of the grouting pipe 3, the filling grouting head 4 and the grouting through hole 5.

[0026] Please see Figures 1 to 4 It also includes a grout inlet pipe 6, which is fixed to the other end of the grouting pipe 3. A slope 17 is provided on one side of the first limiting block 10.

[0027] It is understood that the present invention provides an inclined surface 17 on one side of the first limiting block 10. When the grouting pipe 3, the filling grouting head 4 and the grouting through hole 5 are pushed inward, the grouting pipe 3 will drive the limiting groove 13 to push the inclined surface 17. Pushing the inclined surface 17 will press the first limiting block 10 into the first outer fixing box 9, which facilitates the adjustment of the grouting pipe 3, the filling grouting head 4 and the grouting through hole 5.

[0028] Please see Figures 1 to 4 A pull rod 8 is fixedly connected to the bottom of the inner sliding plate 7. The pull rod 8 is slidably connected to the first outer fixed box 9. A pull block 11 is fixedly connected to one end of the pull rod 8.

[0029] It is understood that in this utility model, the pull rod 8 is pulled by the pull block 11, and the pull rod 8 drives the inner sliding plate 7 and the first limit block 10 to move, so that the first limit block 10 is separated from the limit and fixed between it and the limit slot 13.

[0030] Please see Figures 1 to 4 The first outer fixed box 9 is symmetrically equipped with a return spring 12, one end of which is fixedly connected to the inner sliding plate 7.

[0031] It is understood that this utility model uses the reset spring 12 to reset and move the inner sliding plate 7 and the first limiting block 10, so that the first limiting block 10 can enter the limiting slot 13 for limiting and fixing.

[0032] Please see Figures 1 to 4 The internal threaded connection of the second external fixing box 14 is a limit bolt 16, and one end of the limit bolt 16 is rotatably connected to the second limit block 15.

[0033] It is understood that this utility model uses the rotation of the limiting bolt 16 to move and adjust the second limiting block 15, thereby limiting and fixing the second limiting block 15 and the limiting slot 13, thus restricting and fixing the adjusted position of the grouting pipe 3.

[0034] Please see Figures 1 to 4 It also includes a limiting strip 18, which is fixedly connected at equal intervals to the outside of the grouting pipe 3. The fixed bracket 1 and the mounting side plate 2 are slidably connected to the limiting strip 18.

[0035] It is understandable that the limiting strip 18 of this utility model limits the sliding within the fixed bracket 1 and the mounting side plate 2, thereby ensuring the stability of the grouting pipe 3 adjustment.
