Method for intelligent trial preparation of 3D printing hybrid fiber concrete and control system

Abstract

The invention discloses a method for intelligent trial preparation of 3D printing hybrid fiber concrete and a control system. The method comprises the following steps: respectively establishing a mixing amount ratio database and a measurement result database for 3D printing test blocks; configuring M mixing amount categories and N mixing amounts under each mixing amount category; reading current mixing amount ratio data in the mixing amount ratio database, and preparing concrete stirring slurry according to the current mixing amount; performing 3D printing on the concrete test blocks with the current mixing amount ratio data, measuring the fluidity and the slump of the test blocks, and storing the measurement result as a group of data in the 3D printing test block measurement result database; maintaining and testing the compressive strength of the concrete test blocks by adopting a standard method, and establishing a neural network model; and applying a learning result of a neural network. The control system comprises a mixing amount ratio and measurement result database unit, a concrete mixing control unit, a 3D printing test block unit, a neural network learning unit and a learning result application unit.

Description

Technical field [0001] The present invention relates to a 3D printing concrete technology field. In particular, there is a smart test with 3D print hybrid fiber concrete method and control system. Background technique [0002] In the field of engineering construction, 3D printing technology has fully automated, not subject to complex construction, and is not subject to construction environment restrictions. With the development of large 3D printing equipment and the development of 3D printing technology, there have been several 3D printed practical engineering applications. In 2013, London was established in London, the first 3D print house concept. In 2015, the Netherlands Entinfen University of Technology began to develop giant concrete 3D printers, printing 9.0 × 4.5 × 3m, completed a concrete bicycle bridge between span. In 2016, the Catalonian High School of High School of Spain printed a rack of 12m and 1.75m long. In 2019, Professor Ma Guowei, Hebei University of Technolog...
