Application of Grouting Reinforcement Technology in Bridge Pile Foundation Construction
In order to effectively improve the construction quality of bridge pile foundations,this article takes the construction project of the E2 area overpass and road connecting Bei'an Avenue as the research object.Through the pneumatic hammer drilling grouting technology,the reinforcement of bridge pile founda-tions is achieved to enhance their bearing capacity.Firstly,introduce the grouting process for bridge pile foundations;Secondly,select two pipe piles and analyze the high stress variation measurement and static load situation before and after grouting;Finally,the effectiveness of grouting reinforcement was analyzed,and the experimental results showed that after grouting reinforcement was applied to the bridge pile foundation,the bearing capacity of the pile foundation was improved to a certain extent,and the settlement of the pile foun-dation was reduced.This can provide corresponding reference for similar projects.
