Precast sleeve grouting connection is achieved by inserting steel bars into the sleeve through the openings at both ends.

High strength micro expansion structural grouting material is filled between the steel bars and the sleeve.

With the micro expansion characteristics of the grouting material and the confinement effect of the sleeve, the frictional force between the steel bars and the sleeve is enhanced to achieve stress transmission of the steel bars.

The quality of grouting or unqualified grouting process will affect the connection of precast components, thereby affecting the stability of the structure.
