Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a grouting device for gaps in civil engineering structures. Background Technology

[0002] In civil engineering, structural gaps are a common problem. If not treated in time, they can easily lead to rainwater leakage, steel corrosion, and a decrease in structural load-bearing capacity. Therefore, it is necessary for operators to use grouting equipment to effectively grout the gaps. For example, patent document CN218581241U discloses a grouting device for structural gaps in civil engineering. This device, through the combined action of an outer frame, a mixing motor, a main stirring rod, a secondary stirring rod, and a discharge hole, can ensure that the materials are evenly mixed when mixing mud and sand, avoiding insufficient mixing that could lead to air bubbles after use. The feed port is set at the left end of the outer frame. After the mud and sand are put in, the mixing motor is started, which drives the main stirring rod to rotate and mix. Then, the main stirring rod drives the secondary stirring rod to mix the materials thoroughly. Finally, the mixed slurry is discharged into the conveying equipment through the discharge hole.

[0003] However, the existing grouting equipment is relatively large and can only be moved and used on the ground. When the required grouting gap is located on the wall or at a high position on the top of the wall, the equipment cannot be effectively transported and used, which reduces the effectiveness of the grouting equipment.

[0019] This utility model discloses a grouting device for structural gaps in civil engineering projects.

[0020] This utility model provides, for example Figure 1-3 The invention relates to a grouting device for structural gaps in civil engineering, comprising a grouting gun 1, a filling cavity inside the grouting gun 1, a drive shaft 2 rotatably passing through the side of the filling cavity, a conveying blade 3 fixedly sleeved on the shaft wall of the drive shaft 2, the conveying blade 3 being a spiral conveying blade, a control motor 4 fixedly mounted on the outer wall of the grouting gun 1, the output shaft of the control motor 4 being fixedly connected to the drive shaft 2, a guide shroud 5 fixedly mounted at the outlet end of the filling cavity, a connecting pipe 6 fixedly passing through the end of the guide shroud 5, the connecting pipe 6 being a gooseneck pipe, and a nozzle 7 connected to the opening of the connecting pipe 6; A feed pipe 8 is fixedly inserted through the top of the grouting gun 1. The lower end of the feed pipe 8 is located in the filling cavity. A connecting component is provided at the upper end of the feed pipe 8. A support ring 9 is fixedly sleeved on the outer wall of the grouting gun 1. A rotating ring 10 is rotatably provided on the outside of the support ring 9. Multiple connecting plates 11 are fixedly provided on the outer wall of the rotating ring 10 in an axially uniform manner. A sleeve 21 is fixedly provided on the outer wall of the connecting plate 11. Multiple sleeves 21 are plastic sleeves and have an arc-shaped longitudinal section. A grout bottle 12 is snapped into the inside of the sleeve 21. The grout bottle 12 is configured to cooperate with the connecting component. A bottle cap 18 is threaded onto the bottle mouth of the grout bottle 12. A transparent indicator plate 19 is fixedly embedded on the side of each grout bottle 12. A control switch 13 is fixedly installed on the inner wall of the grouting gun 1, and the control switch 13 is configured in conjunction with the control motor 4.

[0021] To enable rapid switching and positioning of multiple slurry bottles, the number of slurry filling cycles is reduced, such as... Figure 2-3 As shown, the outer wall of the support ring 9 has an annular groove 20, and the rotating ring 10 is rotatably disposed in the annular groove 20. The connecting assembly includes a support plate 14, which is fixedly disposed on the top of the grouting gun 1 and has a sleeve 15 slidably inserted inside. A corrugated pipe 16 is connected between the sleeve 15 and the feed pipe 8. The sleeve 15 is sleeved with the mouth of the grout bottle 12. A spring 17 is sleeved on the outer wall of the sleeve 15, and the two ends of the spring 17 are fixedly connected to the support plate 14 and the sleeve 15, respectively.

[0022] Working principle: First, select the appropriate grouting material according to the type and width of the gap to be grouted, and put the prepared grout into multiple grout bottles 12. The transparent indicator plate 19 on the side of the grout bottle 12 can be used to visually observe the remaining grout inside, so as to make it easy to judge whether it needs to be replenished. The grout bottle 12 filled with grout is fixed to the connecting plate 11 by clamping sleeve 21. The clamping sleeve 21 is a plastic clamp with an arc-shaped longitudinal section, which has a certain elasticity and can fit tightly against the outer wall of the grout bottle 12 to ensure stable fixation. At the same time, the plastic material can avoid scratching the grout bottle 12. Then, the operator holds the grouting gun 1 and adjusts the posture according to the position of the gap to be grouted. If the initial grout bottle 12 is not aligned with the connecting component, the rotating ring 10 can be rotated. The rotating ring 10 rotates in the annular groove 20 on the outer wall of the support ring 9, driving the connecting plate 11 and the grout bottle 12 to rotate synchronously until the target grout bottle 12 is aligned with the sleeve 15 of the connecting component. Then, the sleeve 15 is pushed and moves along the sliding hole of the support plate 14 toward the grout bottle 12. At the same time, the spring 17 is compressed, and the sleeve 15 is fitted onto the bottle mouth of the grout bottle 12. After the sleeve 15 is released, the spring 17 returns to its original position under the action of elastic restoring force, pushing the sleeve 15 to fit tightly with the bottle mouth of the grout bottle 12, so as to realize the connection between the grout bottle 12 and the feed pipe 8. Once ready, the operator presses the control switch 13 on the inner wall of the grouting gun 1. The control switch 13 triggers the start of the control motor 4. The output shaft of the control motor 4 drives the drive shaft 2 to rotate. The spiral conveying blade 3, which is fixedly sleeved on the shaft wall of the drive shaft 2, rotates synchronously. When the spiral conveying blade 3 rotates in the filling cavity, it generates axial thrust, which transports the slurry in the slurry bottle 12 through the sleeve 15, the corrugated pipe 16, and the feed pipe 8 into the filling cavity. Subsequently, under the continuous push of the conveying blade 3, the slurry flows towards the guide shroud 5 at the outlet end of the filling cavity. The guide shroud 5 plays a converging and guiding role for the slurry, allowing the slurry to smoothly enter the connecting pipe 6. The connecting pipe 6 is a gooseneck pipe with flexible characteristics. The operator can flexibly adjust the bending angle of the connecting pipe 6 according to the position of the gap, so that the nozzle 7 is accurately aligned with the gap to be grouted. Finally, the grout is injected into the structural gap under pressure through the nozzle 7 to complete the grouting operation. If the grout in the current grout bottle 12 is exhausted, the rotating ring 10 can be rotated again to switch to the next grout bottle 12 containing grout, and the above docking steps can be repeated to continue grouting, reducing the number of grout replenishments and improving grouting efficiency. After grouting is completed, the control motor 4 is turned off, the empty grout bottle 12 is removed and replaced with a new one, or the device is cleaned and maintained for subsequent use.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
