Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically to a grouting device for pile foundations under complex geological conditions. Background Technology

[0002] When performing pile foundation grouting construction under complex geological conditions, it is necessary to flexibly adjust the angle and direction of the grouting head according to different geological conditions and construction requirements to ensure that the grout can be injected evenly and effectively around the pile foundation, thereby improving the bearing capacity and stability of the pile foundation.

[0003] However, existing pile foundation grouting devices have many problems in adjusting the angle and direction of the grouting head. Most of them change the angle and direction of the grouting head by adjusting the entire grouting pipe. This method is cumbersome, not only consuming a lot of manpower and time, but also having low adjustment accuracy, making it difficult to meet the construction needs under complex geological conditions.

A strip-shaped opening is opened on the side wall of the rotating bar. A round pin is rotatably mounted at the lower end of the adjusting rod, with one end of the round pin extending to the inner side of the strip-shaped opening.

[0008] Preferably, the second transmission mechanism includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the outer wall of the rotating pipe. A side plate is fixedly provided on one side of the bottom end of the grouting pipe. A transmission rod is rotatably provided on the side plate near the rotating pipe.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, the extension of the electric push rod piston rod can push the horizontal plate to move, and the horizontal plate drives the adjusting rod to move, thereby causing the round pin to slide in the strip-shaped opening, so that the grouting head can rotate around the first connecting rod as the axis, thus enabling time-saving and labor-saving adjustment of the grouting angle.

[0018] This utility model discloses a grouting device for pile foundations under complex geological conditions.

[0019] Reference Figure 1-3 A grouting device for pile foundations under complex geological conditions includes a grouting pipe 1 and a grouting head 4. The grouting head 4 is located below the grouting pipe 1. A first through hole is opened at the bottom of the grouting pipe 1. A rotating pipe 2 is rotatably installed on the lower side of the first through hole. An arc-shaped shell 3 is fixedly installed at the lower end of the rotating pipe 2. An arc-shaped concave surface is provided on the side of the grouting head 4 near the arc-shaped shell 3. The arc-shaped concave surface abuts against the arc-shaped convex surface of the arc-shaped shell 3. A sealing gasket is provided on the outer wall of the arc-shaped convex surface of the arc-shaped shell 3 to improve the sealing between the arc-shaped shell 3 and the grouting head 4. A feed port is opened in the middle of the arc-shaped concave surface of the grouting head 4, and a discharge port is opened in the middle of the arc-shaped convex surface of the arc-shaped shell 3. A first transmission mechanism for driving the grouting head 4 to rotate is provided on both sides of the arc-shaped shell 3, and a second transmission mechanism for driving the rotating pipe 2 to rotate is provided on one side of the bottom end of the grouting pipe 1.

[0020] Reference Figure 1-3 The first transmission mechanism includes a rotating bar 6 and an adjusting rod 9. First connecting rods 5 are rotatably mounted on both sides of the arc-shaped shell 3. The rotating bar 6 is fixedly sleeved onto the wall of the first connecting rod 5. A second connecting rod 7 is fixedly sleeved at the lower end of the rotating bar 6. One end of the second connecting rod 7 is rotatably connected to the outer wall of the grouting head 4. An electric push rod 11 is fixedly mounted on one side of the bottom end of the grouting pipe 1. A horizontal plate 10 is fixedly mounted at the end of the piston rod of the electric push rod 11. Two adjusting rods 9 are fixedly mounted at both ends of the horizontal plate 10. The rotating bar 6 has a strip-shaped opening on its side wall. A round pin 8 is rotatably installed at the lower end of the adjusting rod 9. One end of the round pin 8 extends to the inside of the strip-shaped opening. Both the round pin 8 and the inner wall of the strip-shaped opening are coated with a wear-resistant coating to improve their wear resistance. Fixed pipes 12 are fixedly installed at the bottom of the grouting pipe 1 on both sides of the electric push rod 11. A movable rod 13 is movably sleeved inside the fixed pipe 12. The lower end of the movable rod 13 is fixedly connected to the horizontal plate 10, so that the horizontal plate 10 can move stably.

[0021] Reference Figure 1-3The second transmission mechanism includes a first bevel gear 16 and a second bevel gear 18. The first bevel gear 16 is fixedly sleeved on the outer wall of the rotating pipe 2. A side plate 14 is fixedly installed on one side of the bottom end of the grouting pipe 1. A transmission rod 15 is rotatably installed on the side plate 14 near the rotating pipe 2. The second bevel gear 18 is fixedly sleeved on the rod wall of the transmission rod 15. The first bevel gear 16 and the second bevel gear 18 are meshed and connected. A motor 17 is fixedly installed on the side plate 14 away from the transmission rod 15. The output end of the motor 17 is fixedly connected to one end of the transmission rod 15.

[0022] In this utility model, during use, the grouting pipe 1 is first fixed above the pile foundation construction hole. When it is necessary to adjust the angle of the grouting head 4, the electric push rod 11 is activated, and its piston rod extends to push the horizontal plate 10 downward. The horizontal plate 10 drives the adjusting rods 9 on both sides to move downward simultaneously. The round pin 8 at the lower end of the adjusting rod 9 slides in the slot of the rotating bar 6. Since the rotating bar 6 is rotatably connected to the arc-shaped shell 3 through the first connecting rod 5, the sliding of the round pin 8 will drive the rotating bar 6 to rotate around the first connecting rod 5 as the axis. Then, through the second connecting rod 7, the grouting head 4 is pushed to deflect around the arc-shaped convex surface of the arc-shaped shell 3, thereby realizing the adjustment of the grouting angle. The fixed pipe 12 The movable rod 13 ensures the stability of the horizontal plate 10 during movement. If the direction of the grouting head 4 needs to be adjusted, the motor 17 is started, and its output end drives the transmission rod 15 to rotate. The second bevel gear 18 on the transmission rod 15 meshes with the first bevel gear 16 on the outer wall of the rotating tube 2, thereby driving the rotating tube 2 to rotate in the first through hole at the bottom of the grouting tube 1. The arc-shaped shell 3 at the lower end of the rotating tube 2 rotates accordingly, thereby driving the grouting head 4 to adjust its direction and realize grouting operations in different directions. Through independent adjustment of angle and direction, the device can adapt to the grouting needs of different strata under complex geological conditions without adjusting the entire grouting tube, greatly improving construction efficiency.

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.
