Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a foundation grouting device. Background Technology

[0002] Grouting devices inject grout into the pores of the foundation using high-pressure grouting technology, effectively filling voids and reinforcing the soil layer, thereby significantly improving the bearing capacity of the foundation. When constructing equipment foundations on soft soil foundations, grouting can effectively control settlement and ensure the normal operation of the equipment. For defects such as cracks and voids in the foundation, grouting can repair and reinforce them. In areas with complex geological conditions or those greatly affected by external factors, grouting can improve the stability of the foundation and prevent problems such as slippage or tilting of the foundation.

[0003] For example, a foundation grouting device disclosed in the authorization announcement number CN221567165U includes a frame, a storage box fixedly installed on one side of the top of the frame, a motor installed on the top of the storage box, an outer cylinder fixedly installed on one side of the frame, an inner cylinder movably installed inside the outer cylinder, a nut seat fixedly installed inside the inner cylinder, and a lead screw movably installed on the inner wall of the nut seat. The connection between the lead screw and the nut seat is a threaded connection.

[0004] Although it allows for adjustment of the height of the push rod according to the user's height, making it convenient for workers of different heights to move the grouting device, by setting a scraper, when the motor drives the stirring rod to rotate, the scraper also rotates with the stirring rod. The scraper in the rotating state can scrape the material on the inner wall of the storage tank, scraping the slurry off the inner wall of the storage tank, so that the slurry is not easy to remain and adhere to the inner wall of the storage tank, thus playing a certain role in cleaning the inner wall of the storage tank.

[0005] However, this does not solve the problem that existing grouting devices of this type are generally not convenient for adjusting the height of the foundation for grouting, nor are they convenient for adjusting the angle for grouting in complex locations. This greatly affects the convenience of adding grout to the grouting device, as well as the flexibility and efficiency of grouting the foundation by rotating the grouting device.
