Cement stabilized macadam continuous mixing construction water content control device and method

Abstract

The invention discloses a cement stabilized macadam continuous mixing construction water content control device and method. The device comprises fluidity detection devices and a mixing water adding amount complete control device, wherein the fluidity detection devices are used for indirectly measuring the water content of the cement stabilized macadam and are arranged in each of a mixing station and a construction site, the mixing water adding amount complete control device comprises data processors and an electric flow meter, the input ends of the data processors are correspondingly arranged at the mixing station and the construction site and are connected to the fluidity detection devices, and the data output ends of the data processors are connected to an electric flow meter of the mixing station. According to the method, the unique corresponding relation between the fluidity and the water content of the same mixture is utilized, the fluidity measured on a construction site and the fluidity input by a mixing station are analyzed and compared by means of the data processors, and finally a signal is sent out from the output end to control the electric flow meter to automatically adjust the mixing water adding amount.

Description

technical field [0001] The invention belongs to the technical field of mixing road building materials, and in particular relates to a device and method for controlling water content in continuous mixing construction of cement-stabilized gravel. Background technique [0002] Cement-stabilized macadam is usually mixed with a special mixing station for continuous centralized mixing. This process can better ensure the stability of the gradation of the cement-stabilized macadam mixture and ensure the overall quality of the base. Nevertheless, some technical parameters of cement-stabilized gravel mixtures will still vary during the process of mixing and transportation, and cannot be kept constant, such as cement content, mineral material gradation, water content and other parameters in cement-stabilized gravel mixtures. It is in a certain changing process throughout the production process, and it cannot be completely consistent with the design value. [0003] Considering that the...

Problems solved by technology

[0005] (1) The initial mixing water addition control is mainly based on the judgment of the person in charge of the mixing station based on experience, which is highly subjective and not accurate enough;

[0006] (2) After the finished material is transported to the site, since the water content is difficult to measure, the person in charge of the construction can only judge whether the water content is close to the optimal water content based on experience, and then give feedback to the person in charge of the mixing station, which is very likely to cause Causes poor information transmission, making the adjustment of the amount of water added during mixing inaccurate

Due to the above reasons, the final construction water content is often far from the optimal water content, and the performance of the base layer is not ideal.
