Embodiment

[0031] Embodiment: the system block diagram of the present embodiment is as figure 1 As shown, it includes the terminal server and the rheometer at the outlet of the mixing building and the rheometer at the pouring site that are connected in communication with it. Communication between the rheometer and the terminal server for concrete work performance data and feedback information.

[0032] Among them, the rheometer at the outlet of the mixing building and the rheometer at the pouring site are all manipulator rheometers, such as figure 2 As shown, it includes a vertical frame 1, a manipulator 2, a rotating shaft and a welding blade 3, a torque sensor module 4, a distance sensor module 5, a temperature and humidity sensor module 6, and an intelligent module 7. The vertical frame 1 and the manipulator 2 are free to expand and contract, and the manipulator 2 can rotate horizontally around the vertical frame 1. The rotating shaft and the welding blade 3 are located at the end ...

Abstract

The invention discloses an online intelligent monitoring method for working performance of concrete at a construction site. Through real-time collection and detection of an ageing change rule of rheological parameters of mixtures in the same mixing batch at a mixing floor discharge hole and the construction site, and the methods of analyzing, evaluating and feeding back by a terminal server, the working performance of the concrete in construction and transportation processes is monitored in real time. According to the online intelligent monitoring method, automatic intelligence of the detection process is achieved, overlarge deviation in difference of the working performance of the concrete at the construction site can be avoided, and the quality stability of the concrete mixture is ensured.

Description

technical field [0001] The invention specifically relates to an on-line intelligent monitoring method for concrete working performance and quality at a construction site. Background technique [0002] The working performance of concrete refers to the performance of the well-mixed concrete that can be transported, poured and vibrated smoothly without segregation and bleeding. Testing and evaluating the working performance of mixtures has always been one of the important links in the quality control of concrete construction sites. At present, the slump method is used for on-site testing, but it has obvious defects, such as large manual operation errors, certain operating skills are required, the working performance of the mixture is different in the scope of application, and the physical meaning is not clear. [0003] For this purpose, the rheological parameters of concrete (yield shear stress τ 0 and plastic viscosity η) tests to evaluate its working performance and related...
