Description

Technical Field

[0001] This application relates to the technical field of material grouting, and in particular to a material grouting device and method for water conservancy and hydropower engineering construction. Background Art

[0002] The grouting material is prepared with high-strength materials as aggregates, cement as a binder, supplemented by substances such as high fluidity, slight expansion, and anti-segregation. A certain amount of water is added to it at the construction site, and after being stirred evenly, it is poured into the designated position.

[0003] After retrieval, the existing patent publication number: CN218090863U discloses a material grouting device for water conservancy project construction, which includes a moving frame, a mixing tank fixedly installed on the surface of the moving frame, and a grouting mechanism fixedly connected to the front end of the moving frame. A shock-absorbing mechanism is arranged between the moving wheels and the moving frame. The grouting mechanism is composed of a grouting pipe, a corrugated pipe, a micro vibrator, and a vibrating rod. Through the setting of the mixing tank and the internal mixing mechanism, the purpose of improving the grouting quality is achieved. The shock-absorbing mechanism can prevent the electrical components from being damaged by vibration. Through the setting of the micro vibrator, the grouting efficiency is improved and blockage is prevented. Through the setting of the vibrating rod, during grouting, the air bubbles in the slurry during grouting can be discharged through vibration by the vibrating rod, improving the density of the slurry, and achieving the purpose of further improving the grouting quality. The inventor found the following problems in the prior art during the implementation of this application: The existing water conservancy project material grouting device requires manual insertion of the grouting pipe into the holes to be grouted. During the grouting process, some grouting materials will be spilled on the ground, and some slurry will also adhere to the outside of the pipe. When connecting manually, the grouting area spilled at the construction site will be expanded, making it difficult to clean, increasing the labor of workers. Moreover, the existing water conservancy project material grouting cannot clean the inner wall of the mixing device in time after grouting. When the slurry solidifies in the mixing device, it will make the mixing device difficult to clean, affecting the use of the mixing device next time; Therefore, in view of the above related technical problems, a material grouting device and method for water conservancy and hydropower engineering construction are proposed.

Compared with the prior art, for the material grouting equipment and method for water conservancy and hydropower engineering construction, it can actively switch between stirring and cleaning operations, reducing the resistance during stirring, and can scrape the slurry on the inner wall and bottom of the mixing material barrel clean. The switching cylinder drives the lifting sleeve to move up and down, and during the up and down movement of the lifting sleeve, multiple groups of stirring connection plates are driven to expand or contract through the adjusting connection plate and the connecting rod. When the lifting sleeve moves downward, the fixed plug joint is driven to be inserted into the connection slot, and during the insertion process of the fixed plug joint, the telescopic spring ball connected thereto expands and pops outwards.

A grouting method for a material grouting device used in water conservancy and hydropower project construction, which applies a material grouting device for water conservancy and hydropower project construction described in any one of claims 1-9, characterized in that: The grouting method includes the following steps: Step 1: First, move to the construction site through the moving wheels (11) of the grouting equipment base (1), and move the material grouting equipment to the location where grouting is required. After moving to the designated location, drive the support connecting frame (4) to perform lifting and moving through the lifting cylinder (32) of the lifting connecting frame (3), and drive the double-cylinder reciprocating pumping machine box (5) to perform lifting and moving through the support connecting frame (4). During the moving process of the double-cylinder reciprocating pumping machine box (5), insert the grouting pipe (51) into the hole where grouting is required. Step 2: Then, add the grouting raw materials into the stirring tank (6) through an external pipeline, and add sufficient additives into the additive tank (65). The grouting raw materials directly enter the mixing material barrel (62) through the pipeline, while the additives in the additive tank (65) enter the rotating connecting box (66) through the pipeline and are added into the mixing material barrel (62) through the rotating connecting box (66).

The switching cylinder (63) drives the lifting sleeve (631) to perform a lifting action. During the lifting process of the lifting sleeve (631), it drives the stirring connecting plate (67) and the cleaning scraper (674) connected thereto to complete the opening action. At the same time, the fixed plug joint (633) and the top end of the rotating connecting rod (68) extend into the lifting sleeve (631) to complete the switching action between the stirring and cleaning work; Step Seven: After the switching work is completed, the cleaning scraper (674) and the bottom scraper (681) of the mixing material barrel (62) can be driven to rotate by the stirring motor (64). During the rotation process, the inner wall of the mixing material barrel (62) is scraped by the cleaning scraper (674), and the bottom of the mixing material barrel (62) is scraped by the bottom scraper (681). The slurry scraped in the mixing material barrel (62) is concentrated on one side of the bottom scraper (681) for subsequent collection and cleaning.
