Concrete workability rapid recovery system

Abstract

The invention relates to a concrete workability rapid recovery system. The concrete workability rapid recovery system comprises a workability induction device, a stirring device and an additive automatic spraying device. The system is arranged between a concrete tank truck discharging opening and a concrete pump feeding opening, through the workability induction device, the yield stress and the plastic viscosity of the concrete are measured in real time to judge the concrete workability, data are transmitted to a controller, according to the mixture state, the rotating speed of a stirring blade and the mixing amount of the additive are adjusted in real time, and the concrete workability is rapidly recovered within 15 seconds. The workability rapid recovery system has the advantages of being intelligent, rapid and wide in optimization, the problem that in the construction site, water is added at will can be thoroughly solved, and concrete engineering high-quality construction under adverse factors such as raw material quality fluctuation, environment temperature change and long-distance transportation can be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, in particular to a concrete workability rapid recovery system. Background technique [0002] With the continuous advancement of my country's engineering construction, structures with the characteristics of super long, super high and super large are constantly emerging in the project, and corresponding construction technical problems have also emerged. Taking the Sichuan-Tibet Railway, which is about to start construction in full swing, as an example, the length of the newly built main line is 967.178km, bridges and tunnels account for 92.5%, and the longest single tunnel can reach more than 40km. After fresh concrete is transported over a long distance, workability loss will inevitably occur, which will affect the concrete pumping construction. When the workability of the concrete on the project site is lost, the phenomenon of construction workers adding water to the concrete at will o...
