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...

Embodiment 1

[0042] In this step, through the basic idea of ​​"special skeleton + knowledge engineering + template", based on the user-defined template (UDF) function in 3DE, a parameterized template for grouting flat holes is established. The input elements of the template are: the ventilation shaft, the grouting flat hole of each layer, and the axis connecting the branch holes. The template input parameters are: grouting flat hole net width, net height, side wall thickness, floor thickness, top angle, drainage ditch depth, drainage ditch bottom width, and drainage ditch top width. The template calling process is as follows: a. Open the source file in the 3DE user feature calling command, and follow the prompts to select the previously established "ventilation shaft", "grouting flat hole" and "connecting branch hole axis". b. After clicking OK, a 3D model including ventilation shafts, grouting flat holes, and connecting branch holes will be generated. c. According to the needs of users, ...

[0049] According to the hydrogeological conditions, the spatial relationship between the grouting flat holes of each layer and the hub building, the arrangement of grouting holes in different parts is summarized, and the key parameter set of grouting holes (number of rows, row spacing, hole spacing, hole angle, hole depth, etc.) is determined, And based on the above parameters, a user-defined template (UDF) for grouting holes is established. The input elements of the template are: the distance between the bottom of the grouting hole (X2), the distance between the opening of the grouting hole (X1), the number of grouting holes (n), and the initial distance between the holes , The initial hole distance at the bottom of the hole. The template call process is: a. Open the source file in the 3DE user feature call command, and select the previously established "grout curtain hole axis, hole start point" and "grout curtain hole bottom axis, hole bottom start point" according to the pr...
