Description

Technical Field

[0001] The utility model relates to the technical field of grouting pipe cleaning, in particular to a simple auxiliary plugging tool for a cast-in-place pile grouting pipe. Background Art

[0002] The grouting pipe is a pipe used for grouting operations during construction, usually made of plastic or metal, one end of which is connected to the grouting equipment and the other end is inserted into the gap or hole that needs grouting, so as to transport grouting materials such as cement to the building that needs to be reinforced and filled. When the grouting pipe is inserted into the pile hole, it is easy to be blocked and affect the flow of grouting materials, so it needs to be unplugged. This solution specifically relates to a simple auxiliary unplugging tool for the grouting pipe of the cast-in-place pile;

[0003] When the existing simple auxiliary plugging tool for bored pile grouting pipe is used, the solidified accumulated blockage adheres to different positions of the inner wall of the grouting pipe body, which is not convenient for unplugging and cleaning at different depths, and is not convenient for crushing and removing. The accumulation of blockage affects the inflow of grouting material, which has a certain impact on actual use. Utility Model Content
