Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction, and in particular to a grouting device for karst cave pile foundations. Background Technology

[0002] When constructing pile foundations under karst geological conditions, the presence of karst caves can seriously affect the bearing capacity and stability of the pile foundations. Therefore, it is necessary to reinforce the karst cave areas, seal the cavities, and prevent the collapse of the holes through grouting technology to ensure the quality of the pile foundation project.

[0003] Existing grouting devices for karst cave pile foundations mostly have fixed grouting heads, which can only grout in a single direction. This makes it difficult to accurately directionally grout into the cavity, causing the grout to spread only in a local area. Consequently, some areas within the karst cave are not effectively filled and reinforced, forming weak points, which is quite inconvenient.

[0004] Therefore, it is necessary to design a grouting device for karst pile foundations that can adjust the grouting head at multiple angles to facilitate precise directional grouting and ensure full-section reinforcement of karst caves. Utility Model Content

[0005] To overcome the shortcomings of existing grouting devices for karst cave pile foundations, which mostly have fixed grouting heads that can only inject grout in a single direction and are difficult to precisely directionally inject grout into the cavity, resulting in the grout only spreading in a local area and some areas of the karst cave not being effectively filled and reinforced, this utility model provides a grouting device for karst cave pile foundations that can adjust the grouting head at multiple angles, facilitates precise directional grouting, and ensures full-section reinforcement of the karst cave.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the grouting assembly includes a connecting block 13, a connecting pipe 14, a hydraulic cylinder 15, a rack 16, a second gear 17, a third mounting block 18, and a grouting head 19. The second mounting block 9 is connected to the connecting blocks 13 on both the left and right sides. The grouting pipe 1 on the first connecting sleeve 3 is connected to the lower side of the connecting pipe 1, which has a corrugated structure to facilitate deformation and expansion. The hydraulic cylinder 15 is connected to the left side of the second mounting block 9. The hydraulic cylinder 15 and the processor are electrically connected through a control module. The rack 16 is connected to the telescopic end of the hydraulic cylinder 15. The third mounting block 18 is rotatably connected between the connecting blocks 13.

Then, the cement grout is injected into the cavity by the grouting pump. After the cavity is filled, the angle of the grouting head 19 is adjusted back to the center, and then vertical grouting is performed in the karst cave. This allows for multi-angle adjustment of the grouting head 19, which facilitates precise directional grouting and ensures full-section reinforcement of the karst cave.
