AI Technical Summary
In the construction of rock formation casting piles, the internal mixture of the grouting device is prone to agglomeration during pouring and cleaning, resulting in blind spots in cleaning, and the scraper position is offset when vibrating, which affects the cleaning effect and is not closely attached to the inner wall of the working barrel.
A grouting device for rock formation casting pile construction is designed, using the coordination of a control mechanism, a moving rod, a rotating plate and a spring. The control mechanism drives the movement of the moving rod to avoid contact with the inner wall of the working barrel and reduces friction; during cleaning , the rotating plate is in close contact with the inner wall of the working barrel, increasing the cleaning effect, and preventing the position of the rotating plate from being too largely offset by the spring to achieve effective cleaning.
Through the design of this device, the contact between the rotating plate and the inner wall of the working barrel during the stirring process can be effectively avoided, friction is reduced, and cleaning effect can be improved, ensuring the close contact between the rotating plate and the inner wall of the working barrel is enhanced, cleaning effect can be prevented from position deviation, and improving Cleaning efficiency of grouting device.

[0002] Rock stratum cast-in-place pile construction refers to one of the stages of pouring and processing the excavated positioning pits during the rock stratum construction process. During the construction, it is necessary to carry out grouting and sinking pipes inside the positioning pits. During the processing, it is necessary to lower the steel cage and pour underwater concrete.
[0003] When constructing rock cast-in-place piles, a grouting device is required for grouting operations. The inside of the grouting device is equipped with a component for stirring the internal mixture, which can prevent the internal mixture from agglomerating when pouring. After the grouting treatment, the inside of the grouting device needs to be cleaned. When cleaning, the staff needs to use tools such as water guns to flush the mixture attached to the inner wall of the grouting device. In the process of cleaning, dead corners are prone to appear, and the mixture attached to the inner wall is difficult to clean. When the scraper is continuously cleaning, it will be affected by vibration and its position will be offset, which will cause the scraper to not fit tightly enough with the inner wall of the working bucket, which will affect the cleaning effect of the scraper. For this reason, we provide a grouting device for rock cast-in-place pile construction to solve the above problems. Utility Model Content
