PRE-GROUTING TYPE FULL GROUTING SLEEVE STRUCTURE AND CONSTRUCTION METHOD

摘要

A pre-grouting type full grouting sleeve structure and a construction method therefor. The pre-grouting type full grouting sleeve structure comprises a slurry barrel (1); a slurry overflow hole (2) is provided on a barrel wall of the slurry barrel (1), and barrel opening sealing covers (4) are provided, one at either barrel opening at either end of the slurry barrel (1). A slurry overflow opening sealing cover (5) is provided at a slurry overflow opening of the slurry overflow hole (2), and grouting materials are poured into the slurry barrel (1); and during construction, grouting materials are first poured into the slurry barrel (1), and then steel bars (7) to be connected are directly inserted into the slurry barrel (1). The pre-grouting type full grouting sleeve structure simplifies the construction process of the grouting sleeve, and improves the working efficiency.
