A river model section manufacturing method based on a 3D printing technology

Abstract

The invention provides a river model section manufacturing method based on a 3D printing technology. The method comprises the steps of sectioning the river channel section data according to CAD riverchannel topographic data, then obtaining the corresponding model section data through model scale conversion, manufacturing a three-dimensional section model according to the given model section thickness and width, and converting the three-dimensional section model into section file data capable of being recognized by a 3D printer; and manufacturing and generating a river model test section by adopting 3D printing, and marking the section. The method can be widely applied to river channel water and sand simulation and forecasting. Compared with a traditional method, the method is easy and convenient to operate, is high in efficiency, high in automation informatization, safety, accuracy and reliability, is capable of integrally forming the section at a time, is capable of achieving waterproof and moistureproof long-term storage, is capable of greatly saving labor and equipment cost and is beneficial to environment protection.

Description

technical field [0001] The invention relates to a method for making a section panel for hydraulic and river engineering model tests, and belongs to the technical field of hydraulic and river engineering model tests. Background technique [0002] Many problems involved in the planning, design, construction and operation management of water conservancy projects and other water-related projects often need to be studied and solved with the help of model tests. Model test is an important research method and specialized technology in scientific experiments. At present, river engineering model test has been widely used in engineering practice. The river engineering model test is to use the knowledge of river dynamics, according to the similar principle of water flow and sediment movement mechanics, simulate the boundary conditions and dynamic conditions similar to the prototype, reduce the prototype river channel to a certain scale, and repeat the flow, mud and sediment in the labo...
