Description
Technical Field
The invention relates to a vibration method, in particular to an intelligent vibration method for a high-strength concrete member, and belongs to the field of concrete construction.
Background
In the production process of the high-strength concrete member, the concrete member needs to be densely vibrated after being distributed, the concrete material adopted by the high-strength concrete member is mainly characterized by high tension-resistance, high elastic modulus and tensile strain hardening, and contains a large amount of steel fibers, and in order to ensure the self-distribution of the steel fibers, the steel fibers are technically required not to sink, so that the concrete vibration can not be carried out by adopting the existing member vibration platform, and only manual vibration can be adopted; however, the fluidity of the concrete material is extremely poor, the initial setting time is extremely short (initial setting starts after 30 minutes), and manual vibration cannot guarantee that the distributed concrete is vibrated in such a short time, so that the mechanical vibration rod can be considered for vibration.
In the actual vibrating process, the structural forms of high-strength concrete components of each specification are different, especially for some prefabricated spliced bridge decks, as a plurality of bridge decks are spliced together in a matching way through butted dovetails, the dovetails are arranged on the periphery of the prefabricated bridge decks, and as the prefabricated bridge decks are special in shape and cannot be accurately positioned and vibrated while vibrating the bridge decks, the vibration must be independently carried out on the part, the operation difficulty is increased, the operation time is prolonged, manual control is needed, and the operation process is not intelligent enough; and in the process of vibration occasionally, the phenomenon that some parts are omitted to be vibrated occurs, the parts are easy to have internal defects in the process of solidification and later use, so that the safety problem is caused, and even if the vibration is supplemented after the completion of one vibration process, the optimal time is missed, and the initial setting of the concrete cannot reach the expected vibration quality.
