Description

Technical Field

[0001] The utility model relates to the technical field of mixing piles, in particular to a cement mortar mixing pile. Background Art

[0002] Cement mixing piles are an effective form of soft foundation treatment. Using cement as the primary curing agent, a mixing pile machine sprays the cement into the soil and mixes it thoroughly, causing a series of physical and chemical reactions between the cement and the soil, hardening the soft soil and increasing foundation strength. Cement mixing piles are categorized by their primary construction method: single-axis, double-axis, and triple-axis. While existing cement mortar mixing piles for soft foundation reinforcement generally meet daily usage requirements, they still have some shortcomings that require improvement.

[0003] A Chinese patent document with authorization announcement number CN214695557U discloses a cement mortar mixing pile. This cement mortar mixing pile is equipped with a rotating bearing in the middle position of the top of the mixing head, and a rotating rod is arranged in the middle position of the top of the rotating bearing. The top of the rotating rod is connected to a connecting head, and stirring blades are arranged in the middle positions on both sides of the connecting head. The stirring blades are arranged in a center line symmetrical structure. When the device uses a stirring rod to stir, the rotating bearing can be used to drive the connecting head to rotate. When the connecting head rotates, the stirring blades are used to stir, thereby improving the stirring efficiency, increasing the stirring area, and enhancing the practicality of the device.

[0004] However, when the above scheme is in use, stirring blades are set in the middle position on both sides of the connecting head, and the stirring blades are set in a center line symmetrical structure. When the stirring blades need maintenance, the connecting head and the two stirring blades need to be removed at the same time, which makes maintenance more inconvenient, and the volume stirred by a single stirring blade is small, resulting in low efficiency.

[0035] The connecting section 11 is installed at the end of the stirring head, wherein the middle portion of the connecting section 11 has a through hole 7;

[0036] The mounting section 12 is mounted at the bottom end of the connecting section 11. The middle portion of the mounting section 12 has a cavity connected to the through hole 7. A plurality of feed holes 8 are provided on the outside of the mounting section 12 and between the plurality of chutes 10. The plurality of feed holes 8 are all connected to the cavity of the mounting section 12. When in use, the plurality of feed holes 8 are connected to the cement mortar feed channel via the through hole 7, so that the cement mortar is transported to the outside of the mounting section 12 for mixing through the through hole 7, the cavity of the mounting section 12, and the feed holes 8.

[0037] The auxiliary section 13 is mounted on the bottom end of the mounting section 12 . It should be noted that the auxiliary section 13 is conical in shape, and the rotating blades 6 are mounted on the conical surface of the auxiliary section 13 .

[0038] In this embodiment, by installing the connecting section 11 at the end of the mixing head and connecting the connecting section 11 to the cement mortar feed channel through the through hole 7, the cement mortar is transported to the outside of the mounting section 12 through the through hole 7, the cavity of the mounting section 12 and the feed hole 8 for mixing, so that the cement mortar is mixed more evenly.

[0039] Example 3

[0040] like Figs. 1-2 As shown, a cement mortar mixing pile proposed by the present invention is compared with Example 1.
