Research Summary of Connection Status of Grouting Sleeve for Prefabricated Bridge Pier
In order to understand the research progress of existing scholars on commonly used grouting sleeve connection types for prefabricated bridge piers,the shortcomings of their current research is summarized.Through extensive research and analysis of normative standards and existing literature,the types of grouting sleeve connections in terms of common types,mechanical properties,construction,and quality control are summarized and analyzed.Research has shown that it is necessary to consider the convenience and economy of construction to improve the connection type of grouting sleeves,and to clarify the testing requirements related to the tensile strength and elastic modulus of grouting materials.The universality and applicability of existing technical formulas for the bonding strength of grouting sleeve connection types are not strong,and further in-depth research is needed based on comprehensive consideration of various research results.The practicality of existing non-destructive testing techniques for grouting compactness defects needs to be further verified,and their detection accuracy needs to be further clarified.On the basis of existing technology,the grouting process needs to be further upgraded and improved,and its construction quality control indicators and standards need to be improved.
