Abstract

In this paper, the feasibility of winter construction of steel sleeve grouting connection is studied, and two technical schemes of thermal insulation measures for winter construction are provided. This paper mainly introduces the experimental research work of sleeve grouting by simulating winter construction, including test scheme, test operation flow, test equipment and test data collection and analysis. It is concluded that the thermal insulation measures of prefabricated wall panel covering electric heating blanket, XPS insulation board and sleeve outer wall winding electric companion heat preservation are feasible. Finally, according to the actual project case to verify the feasibility of thermal insulation measures, so that the project can progress smoothly, for similar projects in winter construction to provide reference and reference.
