Embodiment Construction

[0038] The present invention is described in further detail now in conjunction with accompanying drawing.

[0039] Such as figure 1 A rapid modeling method for waterway regulation model for 3D printing is shown, which specifically includes: collection of terrain data, determination of the scope of model making, elimination of abnormal data, determination of flat top elevations on both sides of the model, flat top elevations on both sides of the bank instead of shore elevations, Determination of the elevation of the bottom of the model, integration of model boundary control point data, discrete terrain data, generation of waterway model STL files, model cutting, model block output and printing and other steps.

[0040] 1. Terrain data collection

[0041] Use various surveying facilities to survey and map the river topography of the river section to be rehabilitated, and obtain the initial topographic data of the project river section.

[0042] 2. Determination of the scope of...

Abstract

The invention relates to a rapid navigation channel model modeling method for 3D printing. The method comprises steps that initial terrain data of the engineering river section including the terrain elevation is collected; a model making scope is determined; abnormal data of the initial terrain data is excluded; the model both-side flat top elevation is determined; the model both-side flat top elevation is utilized to replace the shore elevation; the model bottom elevation is determined; model boundary control point data is integrated; discrete processing is carried out; a navigation channel model is generated, the model is cut into a plurality of channel model blocks, and the model blocks are outputted and printed. The method is advantaged in that a digital model which can be identified by a 3D printer can be rapidly established for any complex river terrains, and the river terrain model can be guaranteed to have the relatively high similarity to the prototype.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a rapid modeling method for a channel model for 3D printing. Background technique [0002] Many problems are involved in the planning, design, construction and operation management of water conservancy projects, which often need to be solved by means of physical model tests. Therefore, hydraulic and river engineering model tests have been widely used in engineering practice. Model test is to imitate the original body, reduce the prototype into a model for experimental research according to the similarity criterion, use the model to reproduce the natural situation similar to the original body for observation and analysis, and then extend to the prototype according to a certain similarity criterion. [0003] Due to the complexity of the actual river flow, it will be very difficult to solve the problem of channel obstruction by simply using theoretical method...
