Description

Technical Field

[0001] The utility model relates to the technical field of grouting, in particular to a pile grouting device. Background Art

[0002] Pile grouting refers to the process in which, during civil engineering or construction projects, after bored cast-in-place piles or other types of piles are planted underground, gaps or voids may appear between the piles and the surrounding soil or rock formations due to geological conditions, construction errors or the piles themselves.

[0003] After existing pipe piles are implanted underground, gaps often appear between the pipe piles and the surrounding soil or rock layers due to geological conditions, construction errors or the pile body itself. In order to ensure the stability and bearing capacity of the pipe piles, these gaps need to be grouted. Traditional grouting methods usually use sandy clay directly for grouting, but since sandy clay may contain large particles of impurities, directly grouting into the gaps may result in uneven grouting and poor compactness. Therefore, a pile grouting device is proposed. Utility Model Content
