Curtain grouting three-dimensional visualization model construction method

Abstract

The invention relates to the technical field of water conservancy projects, in particular to a curtain grouting three-dimensional visualization model construction method which comprises the steps: establishing a grouting engineering structure tree according to a dam arrangement scheme and the anti-seepage requirement of the dam arrangement scheme; drawing up plane arrangement of a plurality of curtain lines and corresponding curtain bottom lines, and determining an optimal seepage control engineering plane line; in combination with hydrogeological conditions in the geologic model and spatial arrangement of grouting galleries in the dam body, establishing the spatial axis of each layer of grouting adit; generating a grouting adit model based on the grouting adit three-dimensional template;summarizing grouting hole arrangement forms of different parts, determining a key parameter set, and generating a curtain grouting hole model by adopting a UDF mode based on a template library. The model generated by the method can be updated in time and visually reflect the engineering geological conditions of the grouted stratum, the influence of concealment and complexity of the geological conditions on grouting construction quality can be effectively reduced, and the reasonability and efficiency of seepage control design of water conservancy and hydropower engineering are greatly improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a method for constructing a three-dimensional visualization model of curtain grouting. Background technique [0002] The curtain grouting project in large-scale water conservancy and hydropower projects is a key project for dam water storage and power generation, and its quality will directly affect the normal water storage and power generation of the reservoir and the safe operation of subsequent hydropower stations. During the grouting construction process, there are likely to be grout leakage and grout flow in the geological defects such as karst, faults, and long structural plane development, which will affect the construction quality and progress, and cause a large amount of raw material consumption; There may be situations where the curtain is not fully formed, which will become a major safety hazard in the later curtain operation process. For water c...

During the grouting construction process, there are likely to be grout leakage and grout in the geological defects such as karst, faults, and long structural plane development, which will affect the construction quality and progress, and cause a large amount of raw material consumption; There may be situations where the curtain is not completely formed, which will become a major safety hazard in the later curtain operation process

For water conservancy and hydropower projects with complex geological conditions, traditional two-dimensional seepage control design based on two-dimensional flat cut diagrams, section diagrams, design drawings and other traditional two-dimensional expressions, not only the results are not intuitive enough, but also the use process is complicated and cannot be clearer , Visually display the spatial position, relationship and corresponding grouting data of geological bodies and grouting holes
