Description

Technical Field

[0001] The utility model relates to the field of pile drivers, in particular to a pressure-increasing device for a mixing pile driver. Background Art

[0002] Cement mixing piles are an effective form of soft foundation treatment. They use cement as the main agent of the curing agent. Cement is sprayed into the soil by a mixing pile machine and fully mixed, so that a series of physical and chemical reactions occur between the cement and the soil, which hardens the soft soil and improves the foundation strength. Cement mixing piles are divided into single-axis, double-axis and three-axis mixing piles according to the main construction methods used.

[0003] For example, Chinese patent: Publication No. CN220503881U, a pile mixing machine with a pressurizing device, includes a pile mixing machine column, a motor is installed on the top of the pile mixing machine column, and a lifting threaded rod is installed inside the pile mixing machine column, the outer wall of the lifting threaded rod is connected to a rotating block, and a discharge box is arranged on one side of the rotating block, the interior of the discharge box is connected to a material guide pipe, and the end of the material guide pipe is connected to a material storage box, a booster pump is arranged on one side of the motor, and a drill rod is arranged on the bottom side of the booster pump, and the outer wall of the drill rod is threadedly connected with a first fastening bolt.

[0004] Although the cement slurry is more uniform during the mixing process by providing a mixing blade and a mixing shaft, and the mixing blade and the mixing shaft are provided at the same time, and the pre-mixing sinking speed of the lifting device is reduced, the time of repeated mixing is reduced, and the mixing shaft is detachable from the drill rod through the second fastening bolt, thereby facilitating the disassembly, cleaning and installation of the drill rod, however, under the strong mixing action of the pile mixing machine, the cement slurry is easily splashed to the outside, thereby affecting the surrounding environment of the construction. At the same time, the dust that is easily generated during construction causes the dust to be easily dispersed, which will also greatly affect the surrounding environment.

[0005] For this purpose, we propose a pressurizing device for a pile mixing machine. Utility Model Content
