Title:
INTELLIGENT 3D PRINTING METHOD FOR LARGE THREE-DIMENSIONAL DEEP COMPLEX WORK GEOLOGICAL MODEL
Document Type and Number:
WIPO Patent Application WO/2022/095103
Kind Code:
A1
Abstract:
An intelligent 3D printing method for a large three-dimensional deep complex work geological model, which: first, based on test samples of an intact rock and a rock mass structure on a work site and a similarity ratio between a project prototype and an indoor model, determining physical and mechanical parameters of intact rock and rock mass structure similar material, and selecting a cementing agent; performing small-scale 3D printing tests under different material ratios and 3D printing parameters, and determining the material ratio and the 3D printing parameters of the intact rock and rock mass structure similar material for 3D printing which satisfy preset physical and mechanical parameter indexes; constructing a three-dimensional digital model for the intact rock and the rock mass structure, planning a printing path (3-1), and determining the pore diameters, quantity and combinations of printing heads (3-3); feeding the intact rock and rock mass structure similar material to the printing heads (3-3), which move in the planned printing path (3-1) and print under the control of a 3D printing intelligent coupling control system; and detecting the model printing effects.
