Description

Technical Field

[0001] The invention relates to the technical field of grouting devices, in particular to a grouting device for highway bridge construction and a grouting method thereof. Background Art

[0002] During the construction of highway bridges, it is necessary to build a foundation of appropriate size first. However, cracks or pores are very easy to appear inside the rock foundation. If these cracks or pores are not filled in time, the quality of the constructed highway will be affected, which will be extremely detrimental to the safety of vehicles passing through here in the later stage. Therefore, grouting is required. Grouting is divided into ceramic grouting and construction engineering grouting. Construction engineering is a method of injecting certain solidifying slurries into cracks or pores in the rock foundation by appropriate methods, and improving its physical and mechanical properties through replacement, filling, extrusion and other methods.

[0003] Chinese patent publication number CN115198662B discloses "a grouting device for highway bridge construction", which involves grouting, including a support mechanism, the upper surface of which is fixedly mounted with a body by bolts, and a driving mechanism, the interior of which is provided with a grouting tube, the bottom end of which is fixedly connected with a blocking mechanism, and the upper surface of which is provided with a hard guide tube. The patent uses a blocking mechanism to seal the outer grouting groove during the rotation of the grouting tube, so that the inner grouting groove on the guide tube is relatively staggered with the outer grouting groove, thereby preventing mud and debris from falling into the interior of the grouting tube and causing cleaning and affecting subsequent grouting. At the same time, the rotating frame drives the shell on the rotating ring to rotate, so that the inner grouting groove and the outer grouting groove correspond to each other, and the slurry in the grouting tube can be smoothly discharged, so that it can be adaptively adjusted according to the construction progress of highway bridges at different stages. When used in different climatic environments, since the slurry needs to add admixtures according to the different climatic environments, when temporarily adding admixtures to the slurry, the staff needs to use relevant machinery to add and stir the admixtures. The overall operation process is relatively complicated, which reduces work efficiency and may cause delays in construction period and idle work. Therefore, a grouting device and a grouting method for highway bridge construction are proposed to solve the above-mentioned problems. Summary of the invention

The multiple hollow paddles add the admixture to the slurry through the multiple discharge holes above the multiple hollow paddles.

[0032] 2. The grouting device and grouting method for highway bridge construction are provided with four scrapers, so that when the slurry in the mixing bucket is being stirred, the four scrapers can continuously scrape off the slurry attached to the inner wall of the mixing bucket by rotating, thereby preventing part of the slurry from being attached to the inner wall of the mixing bucket for a long time and resulting in inability to fully blend with the admixture, and preventing the slurry from being easily agglomerated when it is attached to the mixing bucket for a long time.

[0033] 3.

DETAILED DESCRIPTION

[0048] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0049] Example 1: Please refer to Figure 1-Figure 4 A grouting device for highway bridge construction includes: a base plate 1, a mounting frame 2 is installed on the base plate 1, a mixing bucket 3 is installed on the mounting frame 2, a buffer bucket 4 is installed on the base plate 1, a feed hopper 8 is installed on the mixing bucket 3, a discharge pipe 9 is connected to the buffer bucket 4, and a grouting pump 10 is connected to the discharge pipe 9. The staff adds slurry into the mixing bucket 3 through the feed hopper 8, and the slurry falls into the buffer bucket 4 through the discharge port on the mixing bucket 3. The staff connects the grouting pipeline to the grouting pump 10, and the grouting pump 10 The slurry in the discharge pipe 9 is transported to the position where grouting is required through the grouting pipeline; the stirring device 5 is used to add an additive to the slurry and stir and mix the additive with the slurry. The stirring device 5 is arranged on the mounting frame 2. The stirring device 5 includes a medicine box 51, and the medicine box 51 is installed on the mounting frame 2. A medicine tube 52 is connected to the medicine box 51. A hollow shaft 53 is rotatably installed at one end of the medicine tube 52 away from the medicine box 51. The staff adds the additive into the medicine box 51, and the medicine box 51 is stirred by the medicine. The tube 52 delivers the medicine to the hollow shaft 53. The bottom end of the hollow shaft 53 is connected to a reciprocating screw rod 61, which is rotatably connected to the buffer bucket 4. A motor 55 is installed on the mounting frame 2. The output end of the motor 55 is connected to a gear rod 56. The outer wall of the hollow shaft 53 is connected to a gear ring 54. The gear ring 54 meshes with the gear rod 56. When the motor 55 is started, the motor 55 drives the gear rod 56 to rotate. The gear rod 56 drives the hollow shaft 53 to rotate through the gear ring 54. When the hollow shaft 53 rotates, it drives the gear rod 56 to rotate through the two hollow tubes 57. The multiple hollow paddles 58 are driven to rotate, and the multiple hollow paddles 58 stir the slurry in the mixing bucket 3 by rotating. Two hollow tubes 57 are installed on the hollow shaft 53, and multiple hollow paddles 58 are installed on the hollow tube 57. The hollow paddles 58 are provided with multiple discharge holes. The inner walls of the hollow shaft 53, the hollow tube 57 and the hollow paddles 58 are communicated, so that the hollow shaft 53 transports the additive to the multiple hollow paddles 58 through the two hollow tubes 57, and the hollow paddles 58 add the additive to the slurry through the discharge holes above them.

[0050] By setting up the stirring device 5, while the multiple hollow paddles 58 are stirring the slurry, the agent box 51 transports the additive to the multiple hollow paddles 58 through the agent tube 52, the hollow shaft 53 and the hollow tube 57 in sequence, and the multiple hollow paddles 58 add the additive to the slurry through the multiple discharge holes above them. Since the additive is added from the inside of the slurry and is accompanied by stirring and mixing, the additive can be more quickly and evenly integrated with the slurry, thereby improving the efficiency of stirring and mixing the additive and the slurry and reducing the operating steps of the staff.

[0051] For further information, see Figure 2-Figure 4 A rotating shaft 59 is rotatably installed at one end of the hollow tube 57 away from the hollow shaft 53, and a friction wheel 510 is connected to the other end of the rotating shaft 59 away from the hollow tube 57. Two scrapers 511 are installed on the outer wall of the rotating shaft 59. A friction groove 512 is arranged inside the stirring bucket 3. Both friction wheels 510 are in contact with the friction groove 512. There is a large friction force between the friction wheels 510 and the friction groove 512. The hollow tube 57 drives the two rotating shafts 59 to rotate. The two rotating shafts 59 can also rotate during the movement. When the rotating shaft 59 rotates, it drives the two scrapers 511 to rotate. When the scrapers 511 rotate, the stirring effect can be promoted.

[0052] By setting the four scrapers 511, when the slurry in the mixing bucket 3 is being stirred, the four scrapers 511 can continuously scrape off the slurry attached to the inner wall of the mixing bucket 3 by rotating, thereby preventing part of the slurry from being attached to the inner wall of the mixing bucket 3 for a long time and resulting in inability to fully blend with the additive, and preventing the slurry from being easily agglomerated when it is attached to the mixing bucket 3 for a long time.

[0053] In this embodiment, the vibration device 6 is used to vibrate and compact the slurry.

[0054] See also Figure 5-Figure 7The vibration device 6 is arranged in the buffer bucket 4. The vibration device 6 includes a sliding frame 63. The sliding frame 63 is slidably installed inside the buffer bucket 4. The surface of the reciprocating screw rod 61 is provided with a reciprocating thread. The inner wall of the sliding frame 63 is slidably connected with the reciprocating thread on the reciprocating screw rod 61 through a ball. The hollow shaft 53 drives the reciprocating screw rod 61 to rotate. The reciprocating screw rod 61 drives the sliding frame 63 to perform vertical reciprocating motion through the cooperation of the reciprocating thread and the ball above it. A vibration frame 64 is installed on the sliding frame 63, and four abutment rods are installed on the vibration frame 64. 65. When the sliding frame 63 moves, it drives the vibration frame 64 to move synchronously. When the vibration frame 64 moves, it drives the four resistance rods 65 to move synchronously. Four sawtooth blocks 66 are installed on the buffer bucket 4. The four resistance rods 65 are respectively in contact with the four sawtooth blocks 66 when moving. When the resistance rods 65 move, they are in contact with the sawtooth blocks 66, so that the resistance rods 65 are subjected to the reverse thrust of the sawtooth blocks 66 and vibrate. When the four resistance rods 65 vibrate, they drive the vibration frame 64 to vibrate, so that the vibration frame 64 can also vibrate during the vertical reciprocating motion.

[0055] By setting the vibration device 6, the vibration frame 64 can perform vertical reciprocating motion and vibrate in the slurry in the buffer bucket 4. The vibration frame 64 transmits the force generated by the vibration to the slurry. After the vibration, the slurry can be denser, thereby improving the grouting quality.

[0056] For further information, see Figure 5 Two scraper rods 62 are installed on the reciprocating screw 61, and a discharge port is provided below the mixing bucket 3. The two scraper rods 62 are in contact with the inner wall of the discharge port. When the reciprocating screw 61 rotates, the reciprocating screw 61 drives the two scraper rods 62 to rotate synchronously. When the two scraper rods 62 rotate, they can promote the falling of the slurry and prevent the slurry from being blocked at the discharge port of the mixing bucket 3.

[0057] By providing the two scraping rods 62 , the two scraping rods 62 can promote the slurry to fall from the discharge port of the mixing bucket 3 by rotating, thereby preventing the slurry from blocking the discharge port.

[0058] Further, see Figure 5-Figure 7 Two connecting rods 67 are hinged on the vibration frame 64, and a sliding rod 68 is slidably installed on the buffer bucket 4. The sliding rod 68 is hinged to one end of the two connecting rods 67 away from the vibration frame 64, and a push plate 69 is rotatably installed on the sliding rod 68. The push plate 69 is slidably connected to the buffer bucket 4. When the vibration frame 64 performs vertical reciprocating motion, the vibration frame 64 drives the sliding rod 68 to slide back and forth in the buffer bucket 4 through the two connecting rods 67. When the sliding rod 68 slides, it drives the push plate 69 to move synchronously, so that the push plate 69 can continuously push the slurry in the buffer bucket 4 toward the discharge pipe 9 through reciprocating motion.

[0059] By setting the push plate 69, the push plate 69 continuously pushes the slurry around the push plate 69 toward the discharge pipe 9, thereby preventing the slurry from flowing unevenly in the buffer bucket 4 and causing part of the slurry to remain stationary for a long time and solidify.

[0060] In this embodiment, the grinding device 7 is used to grind the slurry material.

[0061] See also Figure 8-Figure 10 The grinding device 7 is arranged in the buffer bucket 4, and the grinding device 7 includes a lower grinding block 74, and the lower grinding block 74 is installed inside the buffer bucket 4. An upper grinding block 73 is slidably installed inside the buffer bucket 4, and the upper grinding block 73 is located above the lower grinding block 74. There is a gap between the upper grinding block 73 and the lower grinding block 74. The slurry in the buffer bucket 4 enters the discharge pipe 9 through the gap between the upper grinding block 73 and the lower grinding block 74. A push rod 72 is hinged on the upper grinding block 73, and a fixed rod 71 is connected to the vibration frame 64. The fixed rod 71 is hinged with the push rod 72, and the vibration frame 64 drives the fixed rod 71 to move synchronously. When the fixed rod 71 moves, the upper grinding block 73 is driven by the push rod 72 to perform horizontal reciprocating motion. When the upper grinding block 73 performs horizontal reciprocating motion, the upper grinding block 73 cooperates with the lower grinding block 74 to grind the slurry passing through the gap between the upper grinding block 73 and the lower grinding block 74.

[0062] By setting the grinding device 7, the upper grinding block 73 can grind the slurry passing through the gap between the upper grinding block 73 and the lower grinding block 74 through reciprocating movement, and the larger particles or lumps contained in the slurry can be ground, thereby improving the quality of the slurry. The ground slurry enters the grouting pump 10 through the discharge pipe 9 for grouting operation, thereby avoiding the project quality being affected by the larger particles and lumps contained in the slurry during the grouting process.

[0063] Embodiment 2: A grouting method for highway bridge construction, comprising any one of the above-mentioned grouting devices for highway bridge construction, further comprising the following steps:

[0064] Step 1: Lay out the lines and locate the locations where grouting is required, then drill holes and clean the holes;

[0065] Step 2: After the grouting device is in place, fix the grouting device;

[0066] Step 3: After selecting a suitable grouting pipe, connect one end of the grouting pipe to the grouting pump 10, and fix the other end of the grouting pipe in the borehole to be grouted;

[0067] Step 4: Add the slurry into the stirring bucket 3 through the feed hopper 8, start the motor 55, and stir the slurry;

[0068] Step 5: Add the additive into the reagent box 51 to fully mix the slurry and the additive;

[0069] Step 6: Turn on the grouting pump 10, and the grouting pump 10 transports the grouting material to the borehole that needs grouting through the grouting pipeline;

[0070] Step 7: After the grouting is completed, the grouting pump 10 and the motor 55 are turned off, the grouting pipe is disassembled, the excess grouting material is cleaned, and the surface is processed to ensure the appearance and structural integrity of the grouting part.

[0071] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0072] Working principle: the staff adds the slurry into the mixing bucket 3 through the feed hopper 8, starts the motor 55, the motor 55 drives the gear rod 56 to rotate, the gear rod 56 drives the hollow shaft 53 to rotate through the gear ring 54, and when the hollow shaft 53 rotates, it drives multiple hollow paddles 58 to rotate through two hollow tubes 57. The multiple hollow paddles 58 stir the slurry in the mixing bucket 3 by rotating, and the slurry falls into the buffer bucket 4 through the discharge port on the mixing bucket 3. When it is necessary to add an additive, the staff adds the additive into the medicine box 51, and the medicine box 51 transports the medicine to the hollow shaft 5 through the medicine pipe 52. 3, since the inner walls of the hollow shaft 53, the hollow tube 57 and the hollow paddle 58 are connected, the hollow shaft 53 transports the additive to the multiple hollow paddles 58 through the two hollow tubes 57, and the hollow paddles 58 add the additive to the slurry through the discharge holes above them; when the hollow tube 57 rotates, the hollow tube 57 drives the two rotating shafts 59 to rotate, and since there is a large friction force between the friction wheel 510 and the friction groove 512, the two rotating shafts 59 can drive the two friction wheels 510 to roll on the friction groove 512 when they rotate, and the friction wheel 510 drives the rotating shaft 59 to rotate when it rolls, so that the two The rotating shaft 59 can also rotate during the movement, and the rotating shaft 59 drives the two scrapers 511 to rotate when rotating. The scrapers 511 can promote the stirring effect when rotating, and prevent part of the slurry from adhering to the inner wall of the stirring bucket 3 for a long time and agglomerating. Through the setting of the stirring device 5, the multiple hollow paddles 58 stir the slurry, and the medicine box 51 sequentially transports the additive to the multiple hollow paddles 58 through the medicine tube 52, the hollow shaft 53 and the hollow tube 57. The multiple hollow paddles 58 add the additive to the slurry through the multiple discharge holes above them. The additive is added to the inside of the slurry, and is stirred and mixed, so that the additive can be more quickly and more evenly integrated with the slurry, thereby improving the efficiency of stirring and mixing the additive and the slurry, and reducing the operating steps of the staff; through the arrangement of the four scrapers 511, when the slurry in the mixing bucket 3 is being stirred, the four scrapers 511 can continuously scrape off the slurry attached to the inner wall of the mixing bucket 3 by rotating, thereby preventing part of the slurry from being attached to the inner wall of the mixing bucket 3 for a long time and resulting in inability to fully integrate with the additive, and the slurry is prone to agglomeration when it is attached to the mixing bucket 3 for a long time.

[0073] When the hollow shaft 53 rotates, the hollow shaft 53 drives the reciprocating screw rod 61 to rotate, and the reciprocating screw rod 61 drives the sliding frame 63 to perform vertical reciprocating motion through the cooperation of the reciprocating thread and the ball above it. When the sliding frame 63 moves, it drives the vibration frame 64 to move synchronously, and when the vibration frame 64 moves, it drives the four contact rods 65 to move synchronously. When the contact rod 65 contacts with the sawtooth block 66 during movement, the contact rod 65 is subjected to the reverse thrust of the sawtooth block 66 and vibrates. When the four contact rods 65 vibrate, it drives the vibration frame 64 to vibrate, so that the vibration frame 64 can also vibrate during the vertical reciprocating motion. The vibration frame 64 vibrates and compacts the pulp material in the buffer bucket 4; when the vibration frame 64 performs vertical reciprocating motion, the vibration frame 64 drives the sliding rod 68 to slide reciprocatingly in the buffer bucket 4 through the two connecting rods 67. When the sliding rod 68 slides, it drives the push plate 69 to move synchronously, so that the push plate 69 can move back and forth The slurry in the buffer bucket 4 is continuously pushed toward the discharge pipe 9; when the reciprocating screw 61 rotates, the reciprocating screw 61 drives the two scraper rods 62 to rotate synchronously, and the two scraper rods 62 can promote the falling of the slurry and prevent the slurry from being blocked at the discharge port of the mixing bucket 3 when rotating; through the setting of the vibration device 6, the vibration frame 64 can perform vertical reciprocating motion and vibrate in the slurry in the buffer bucket 4, and the vibration frame 64 transmits the force generated by the vibration to the slurry, and the slurry can be denser after vibration, thereby improving the grouting quality; through the setting of the push plate 69, the push plate 69 continuously pushes the slurry around the push plate 69 toward the discharge pipe 9, avoiding uneven flow of the slurry in the buffer bucket 4, and the phenomenon that some slurry remains stationary for a long time and solidifies; through the setting of the two scraper rods 62, the two scraper rods 62 can promote the slurry to fall from the discharge port of the mixing bucket 3 by rotation, and avoid the slurry blocking the discharge port.

[0074] During the vertical reciprocating motion of the vibration frame 64, the vibration frame 64 drives the fixed rod 71 to move synchronously. When the fixed rod 71 moves, the upper grinding block 73 is driven to perform horizontal reciprocating motion through the push rod 72. Since there is a gap between the upper grinding block 73 and the lower grinding block 74, the slurry in the buffer bucket 4 enters the discharge pipe 9 through the gap between the upper grinding block 73 and the lower grinding block 74. The staff connects the grouting pipeline to the grouting pump 10, and the grouting pump 10 transports the slurry in the discharge pipe 9 to the position where grouting is required through the grouting pipeline to perform grouting operations. When the upper grinding block 73 reciprocates horizontally, the grouting operation is performed. During movement, the upper grinding block 73 cooperates with the lower grinding block 74 to grind the slurry passing through the gap between the upper grinding block 73 and the lower grinding block 74. Through the setting of the grinding device 7, the upper grinding block 73 can grind the slurry passing through the gap between the upper grinding block 73 and the lower grinding block 74 by reciprocating movement, and the larger particles or lumps contained in the slurry can be ground, thereby improving the quality of the slurry. The ground slurry enters the grouting pump 10 through the discharge pipe 9 for grouting operation, thereby avoiding the influence of large particles and lumps in the slurry on the project quality during the grouting process.

[0075] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
