Technical Field
The invention relates to the technical field of bridge engineering, in particular to a mobile device for testing concrete slump.
Background
Slump is a method and an index for measuring concrete workability, and in a construction site, slump test is usually carried out to measure the fluidity of a mixture, and visual experience is used for evaluating the cohesiveness and the water retention. The slump is measured by a quantitative index, and is used for judging whether the construction can be normally carried out.
General slump test method: filling concrete into a horn-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm for three times, tamping by a tamping hammer after each filling, and leveling. Then the barrel is pulled up, the concrete generates the slump phenomenon due to the dead weight, and the height of the highest point of the slump concrete is subtracted from the barrel height (300mm), namely the slump.
The existing field slump test method has the following defects:
firstly, the slump is measured by randomly placing a slump bucket on the ground adjacent to the unloading of a tank truck, and the ground is not hardened, so that the accuracy of slump measurement is influenced due to the fact that the ground is uneven.
Secondly, the entry diameter of slump bucket is 100mm, adopts the spade to pour into the concrete into the slump bucket usually, because the slump entry is less, pours into the in-process and leads to a large amount of concrete to scatter around the slump bucket, causes the concrete extravagant. And the preparation work for cleaning sundries around the slump bucket before the slump test is increased, and the accuracy of the slump test is reduced if the cleaning is not thorough.
And thirdly, after the concrete slump test is finished, the waste concrete needs to be transported to a designated place for treatment, otherwise, the site environment is polluted. The concrete scattered on the ground is not easy to clean, and a special trolley is needed to transport the concrete, so that construction procedures and construction machines are additionally increased.
And fourthly, when large-volume concrete pouring is carried out on site, in order to ensure that the fluidity of the concrete is qualified, the slump test frequency is high, and the existing test mode consumes time and labor.
