Abstract

The invention discloses a leveling device for a slump expansion dial, the leveling device is used for placing the slump expansion dial, the leveling device comprises a balance supporting assembly and three leveling assemblies, the balance supporting assembly is triangular, the balance supporting assembly comprises three balance supporting rods which are connected end to end, and the three leveling assemblies are arranged on the balance supporting rods. The adjacent balance supporting rods form a joint for mounting a leveling assembly; each leveling assembly comprises a leveling piece and a supporting base, the leveling pieces penetrate through the connecting positions and are in threaded connection with the supporting bases, and the three leveling assemblies are adjusted so that accurate measurement of concrete detection can be conducted. The balance supporting assembly and the three leveling assemblies are matched to realize accurate measurement of concrete detection, so that the detection data can be reliably reflected in the concrete detection process, the detection is more convenient, the measurement risk is greatly reduced, and the detection efficiency is improved. The invention further discloses a leveling method of the slump expansion dial.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a leveling device and a leveling method for a slump expansion dial. Background technique [0002] At present, concrete slump mainly refers to the plasticizing performance and pumpability of concrete. The factors that affect concrete slump mainly include gradation change, water content, weighing deviation of weighing apparatus, and dosage of admixtures, which are easily overlooked. Also the temperature of the cement etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. [0003] However, the existing leveling device for the slump expansion scale has the following defects: [0004] The immersed tunnel adopts steel shell concrete tube section, which is a structural form filled with concrete inside a double-layer steel shell. It needs self-compacting concrete that can ach...
