Description

CAD drawing and progress chart combined display method and system for invisible and undispersed tunnel

Technical Field

The application belongs to the field of engineering design, and particularly relates to a CAD drawing and progress chart combined display method and system for a tunnel without scattering.

Background

1) Fixed point is penetrated, namely in the tunnel construction process, in order to ensure the quality and safety of the tunnel, construction needs to be carried out at the two ends of the tunnel at the same time until working surfaces at the two ends are penetrated. Therefore, the problems of deviation, collapse and the like of the tunnel can be avoided, and the quality and the safety of the tunnel can be ensured.

2) The method is characterized in that two working surfaces are constructed in opposite directions, one working surface is constructed from small mileage to large mileage, and the other working surface is constructed from large mileage to small mileage, and according to work efficiency data, the expected convergence mileage and the penetration date are deduced.

3) Safety step: the tunnel safety step distance refers to the distance from the tunnel inverted arch to the tunnel face, or the distance from the tunnel secondary lining to the tunnel face.

4) Tunnel face (tunnel face) refers to an excavation face in an underground or mining project.

5) Surrounding rock grade: and (3) evaluating the property of the surrounding rock, judging the stability of the surrounding rock of the tunnel, wherein the surrounding rock of the tunnel is divided into six stages, namely a first stage, a second stage, a third stage, a fourth stage, a fifth stage and a sixth stage, and the smaller the number, the better the property of the surrounding rock.

6) CAD drawing: CAD (Computer-Aided Design) is an abbreviation for Computer Aided Design and is widely used in a variety of fields including mechanical Design, architectural Design, electronic Design, etc. CAD drawings are two-dimensional or three-dimensional design drawings created using CAD software.

7) DXF: DXF (Drawing Exchange Format) is a file format designed by AutoDesk corporation to allow graphics data of AutoCAD to be used in other software. This format is designed as a standard format for exchanging drawings between different CAD software. DXF files may contain 2D and 3D graphical information including lines, curves, surfaces, entities, text, bitmaps, and the like. It may also contain metadata such as layer, color, and line type.

8) Progress chart (two-dimensional pictogram): a progress chart is a tool for tracking the progress of an item or task. It can help project managers and team members to know the completion of work and whether to proceed as planned. In the system, a time mileage graph is used for presenting, the mileage stake marks of the tunnel are displayed by an abscissa, the planned completion time and the actual completion time of the current mileage stake marks are displayed by an ordinate, and the estimated completion time of the working face on the current working face is calculated according to the work efficiency data.

9) SVG: SVG (Scalable Vector Graphics) is an XML-based vector graphics format widely used to display graphics on the Web. SVG graphics can remain clear at any resolution and are therefore well suited for displaying complex CAD drawings.

10 Work breakdown structure (Work Breakdown Structure, WBS): grouping project elements guided by deliverables generalizes and defines the overall scope of the project with each layer down representing a more detailed definition of project work. WBSs are always at the center of the planning process and are also an important basis for scheduling, resource demand, cost budgets, risk management plans, and procurement plans, among others.

11 The sub-project refers to sub-division of the sub-project, which is a basic project, also called project sub-project or sub-project, constituting the sub-project, and is a construction project or installation project which can be produced through a relatively simple construction process and can be calculated by using a proper measuring unit. Generally, construction items are divided according to different factors such as the selected construction method, the used materials, the specifications of structural members and the like. For example, the method can be divided into brick foundations, brick walls, brick columns, block walls, reinforced brick lintels and the like in masonry engineering, and divided into earthwork, backfill and residual soil outward transportation in earthwork engineering. The number of engineering entities metered in appropriate metering units is the engineering quantity.

The CAD drawings and the progress chart are combined together so that they are displayed simultaneously on one interface. This may allow a project team to more conveniently view and understand the design drawings and project schedules, thereby improving efficiency and productivity.

Prior art and drawbacks thereof

1) AutoCAD software native to AutoDesk does not directly support exporting CAD drawings to SVG format. The official method of displaying CAD drawings on the Web is the Forge platform using AutoDesk, but it displays a master image or renders using WebGL instead of SVG. In addition, some third-party WebGL schemes exist, but the WebGL mode is difficult to combine with the progress chart, mainly for the following reasons:

not vector graphics: webGL is mainly used to render bitmap graphics, while SVG is a vector graphics format. This means that SVG images can be scaled to any size without loss, while WebGL rendered images may be distorted or blurred when enlarged.

Performance requirements: webGL is a GPU-based rendering technology with certain demands on hardware. On some old or low-end devices, webGL may not work or perform poorly.

Compatibility problem: while most modern Web browsers support WebGL, there are some browsers or devices that may not support or require manual enablement by the user. While SVG has a wider compatibility.

Programming complexity: complex 3D rendering using WebGL requires high programming skills and in-depth graphics knowledge. While SVG is relatively simple to use, graphics can be described directly in XML format text.

Difficult to search and index: SVG files can be indexed by a search engine, can be read by a screen reader, and can be selected and copied directly by a user. Whereas WebGL rendered images are in a bitmap form, without these properties.

Interactivity problem: while WebGL can create complex interactive effects, this requires writing a large amount of code. While SVG elements can be controlled directly with HTML and CSS styles and events, they are more suitable for creating simple interactive effects.

2) Converting CAD files to SVG, there are many tools on the web, including some open source and commercial software. For example, you can use LibreCAD, which is an open-source 2D CAD application that exports CAD files into SVG format. Another option is an online conversion tool like "condition. Co" or "angconv. Com", but they each have some limitations:

functional limitations: some tools may not fully support all CAD features and elements, such as fill (latch), custom linetypes, etc. This may result in the converted SVG being different from the original CAD drawing.

Version compatibility problem: CAD file formats (e.g., DXF) have multiple versions, each of which may have different characteristics and formats. Some tools may not support all versions or problems may occur when processing certain versions.

Performance problems: for large CAD files or large numbers of files, some tools may not process efficiently. This may result in the conversion process being too long or consuming too much computing resources.

Complexity of use: some tools may require complex setup or command line operations, or may require knowledge of the expertise of some CAD and SVG. This may increase the difficulty of using the tool and the learning cost.

Integration problem: there may be some restrictions on the use of third party tools if the CAD to SVG conversion process needs to be integrated into your application or workflow. For example, you may need to call tools through a command line or other interface, which may require additional programming effort.

Licensing and cost issues: some tools may require a license to be purchased, or have some usage restrictions. This may increase the cost of using the tool or limit the use of the tool.

Update and maintenance problems: the update and maintenance of the third party tool is dependent on its developer or vendor. If the tool is no longer updated or maintained, or compatibility or security issues occur, you may need to find other tools.
