Embodiment Construction

[0024] like figure 1 As shown, this embodiment provides a concrete segregation detection device, one side of the side wall of the insulating barrel 2 is provided with a plurality of positive electrode joints 9 from bottom to top, and the opposite side of the side wall of the barrel 2 is provided with multiple electrodes from bottom to top. a negative electrode connector 8, the positive electrode connector 9 and the negative electrode connector 8 are at the same level. The positive electrode connector 9 and the negative electrode connector 8 are electrically connected to the resistance meter 4 respectively, and the resistance meter 4 can measure the resistivity of the material in the barrel body 2 . The upper end of the staving 2 is connected to the bung 1 through bolts 7, so that the staving 2 is detachably connected to the bung 1. Open the barrel cover 1, and materials can be added into the barrel body 2. A through hole is provided on the bung 1, and an inner nut 6 is arran...

Abstract

The invention proposes a concrete segregation detection device and method. The concrete segregation detection device includes an insulating barrel, a resistance meter and an air compressor. The opposite sides of the barrel side walls are respectively provided with multiple pairs of positive electrode joints and negative electrodes from bottom to top. The connector, the positive electrode connector and the negative electrode connector are electrically connected to the resistance meter respectively, and the upper end of the barrel body is detachably connected with a bung, the bung is connected to the air compressor through the air guide tube, and the air guide tube is provided with a pressure gauge. The invention has beneficial effects: the concrete segregation environment in the pumping process can be truly restored, and the components at different heights of the segregated concrete can be accurately detected.

Description

technical field [0001] The invention relates to the technical field of concrete segregation detection, in particular to a concrete segregation detection device and method. Background technique [0002] Pumping concrete has the advantages of fast construction speed, good quality, manpower saving and convenient construction, so it is widely used in general building structure concrete, road concrete, mass concrete, high-rise buildings and other projects. However, during the pumping process, due to unreasonable proportioning or improper construction, the pipeline is often blocked. Among them, concrete segregation is an important reason for blockage of pumping pipelines, and segregated concrete affects the final strength of concrete, resulting in poor construction quality. [0003] The Chinese patent literature with the notification number CN102749439B discloses a device for testing and evaluating the segregation phenomenon of freshly mixed concrete, which includes vibrating par...
