Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a mixing and grouting device that is integrated with stirring and grouting. Background Art
[0002] Traditional foundation treatment methods sometimes cannot meet the needs of precise and efficient reinforcement under complex geological conditions. For example, in soft soil foundations and foundations in karst areas, a device is needed that can accurately mix and stir the grouting materials and inject them into different strata at different depths as needed to improve the foundation reinforcement effect. The integrated mixing and grouting equipment came into being. It can better ensure the quality of the grouting liquid, evenly fill the stratum pores, and enhance the foundation strength.
[0003] The existing technology has the following defects or problems: The publication number of the existing technology is: CN218716674U, which relates to the field of engineering machinery and specifically discloses a grouting plug and grouting equipment.

The grouting plug described above connects the control joint to the slurry inlet end of the main body, and the control pipe can be correspondingly arranged inside the slurry conveying pipe, so that the pipe diameters of the main body and the matching pipe are set to be consistent, which provides convenience for the grouting operation.
[0004] During use, the aforementioned equipment struggles to mix the raw materials, resulting in uneven cement distribution. Some areas have excessively high cement content, leading to excessive hardness and shrinkage stress after setting, which can easily cause cracks. Meanwhile, some areas have too little cement, failing to achieve the expected reinforcement strength, impacting the stability and bearing capacity of the entire foundation. However, existing technologies use some integrated mixing and grouting equipment to pour foundations at different depths, which can result in substandard grouting at certain depths. This necessitates subsequent remedial drilling and grouting, increasing construction costs and time.

[0024] In this embodiment, the variable speed motor 3 is started, and the variable speed motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates on the inner wall of the top of the inclined plate 2, ensuring the stability of the rotation. The main blade 5 fixed to the outside of the bottom end of the rotating shaft 4 and the auxiliary blade 6 on the outside of the top end begin to stir the material. Since the main blade 5 is close to the bottom of the mixing tank 1, it is mainly responsible for fully stirring the raw materials accumulated at the bottom to prevent the materials from settling and accumulating at the bottom and being unable to mix evenly.

The dual high-pressure nozzle 20 is equipped with a booster device, which can pressurize the grouting liquid flowing into the steel slurry injection pipe 16 again. The external block 17 can be connected to an excavator or a hook machine.
[0028] The working principle and use process of the present invention are as follows: Start the variable speed motor 3, which drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates on the inner wall of the top of the inclined plate 2, ensuring the stability of the rotation.
