Problems solved by technology

[0005] 1. The on-site test slump is to place the slump barrel at will on the ground near the unloading of the tank truck for measurement. The ground is often not hardened, and the ground is uneven, which affects the accuracy of the slump test.
[0006] 2. The diameter of the entrance of the slump bucket is 100mm. Usually, a shovel is used to pour concrete into the slump bucket. Because the slump entrance is small, a large amount of concrete is scattered around the slump bucket duri

Abstract

The invention discloses a moving device for testing concrete slump, and relates to the technical field of bridge engineering. According to the moving device, the movable base is arranged and comprises the bottom plate and the rolling wheels connected to the lower portion of the bottom plate, so that concrete can be conveniently transported and discarded after testing is completed, and cleaning is easy; the bottom plate is connected with a follower wheel and a steering wheel through height adjusting bolts, so that the moving device has the function of leveling the levelness of the bottom plate, and the measurement is more accurate; and the funnel and the butterfly valve are arranged to control material filling, and concrete is not scattered, so that the concrete is saved, and the field environment is protected. When the mobile device is used for testing the concrete slump, the accuracy is good, the concrete is saved, the workload is reduced, certain economic benefits are achieved, and the environmental pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a mobile device for testing the slump of concrete. Background technique [0002] Slump is the measurement method and index of concrete workability. At the construction site, the slump test is usually used to measure the fluidity of the mixture, supplemented by visual experience to evaluate the cohesion and water retention. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. [0003] General slump test method: use a trumpet-shaped slump barrel with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and fill it three times. After each filling, use a ram to compact it and smooth it . Then pull up the barrel, the concrete will slump due to its own weight, and the height of the highest point of the concrete after the slump is subtracted from the height of t...
