Intelligent prediction method for concrete pumping performance

Abstract

The invention provides an intelligent prediction method for a concrete pumping performance, which belongs to the technical field of concrete pumping performance measurement, and completes concrete pumping performance intelligent test through a data acquisition module, a network training module and a prediction application module in sequence. Firstly, a data acquisition module generates and collects pumping data samples through on-site measurement, theoretical calculation and simulation analysis, and a concrete pumping performance database is constructed; then, on the basis of the pumping performance database, an error back propagation method is adopted to construct a training artificial neural network module; and finally, predicting concrete pumping in a new working condition by utilizingthe trained artificial neural network module, adding real data acquired in the new working condition into the original pumping performance database, and re-operating network training, so that concretepumping construction in the new working condition is guided by utilizing the artificial neural network with relatively high accuracy. According to the intelligent prediction method for the concrete pumping performance, the concrete pumping construction problem is solved.

Description

technical field [0001] The invention relates to the technical field of concrete mixture pumping performance measurement, in particular to an intelligent prediction method for concrete pumping performance. Background technique [0002] Self-compacting concrete materials are commonly used in the construction of super high-rise buildings, and fresh concrete is efficiently transported by powerful pumping equipment for structural pouring. In the process of formulating and implementing the concrete pumping construction plan, pre-evaluating the pumping performance (mainly referring to the relationship between the pumping flow rate and the total pressure loss) is an important prerequisite. In the current industry standard, the calculation formula of pumping pressure loss is derived from the empirical formula for traditional concrete decades ago; with the development and change of concrete performance and engineering complexity, its applicability is doubtful.
