MEASURING SYSTEM AND TEST METHOD FOR FRICTION AT THE INTERFACE BETWEEN PIPE AND CONCRETE IN CONCRETE PUMPING

摘要

To achieve this, according to the present invention, the measuring system for concrete squeeze pumping friction properties, which is to measure concrete squeeze pumping friction properties, comprises: a container formed to be a predetermined shape; a cylinder arranged to be spaced from a central floor portion of the container at a predetermined distance; and a rotation shaft fixedly installed in an upper end of the cylinder. Moreover, to achieve this, according to the present invention, the measuring method for concrete squeeze pumping friction properties, which is to measure concrete squeeze pumping friction properties, comprises the following steps of: preparing the measuring system for concrete squeeze pumping friction properties which comprises the container formed to be a predetermined shape, the cylinder arranged to be spaced from a central floor portion of the container at a predetermined distance, and the rotation shaft fixedly installed in an upper end of the cylinder; filling concrete in the container at a predetermined height; and measuring a rotational force by rotating the cylinder around the rotation shaft.
