Description

Technical Field

[0001] The present invention relates to the technical field of BIM models, and in particular to a method for calculating the quantity of dredging works in water areas of a water transport engineering based on BIM technology. Background Art

[0002] In recent years, BIM (Building Information Modeling) technology has developed rapidly. Relying on advanced digital technology, various key information in construction projects is integrated into three-dimensional models, thereby realizing information sharing and collaborative work. In the field of dredging engineering, BIM software applications represented by Civil 3D are particularly prominent. It can help engineers perform accurate three-dimensional terrain modeling, riverbed scouring and silting simulation analysis, and accurate calculation and statistics of dredging engineering quantities.

[0003] However, the existing dredging engineering quantity calculation method based on BIM technology still has some shortcomings. Non-BIM software is based on traditional process-oriented software. Users need to process a large amount of terrain data and perform a series of calculation steps, which is time-consuming. When processing large or complex terrain data, performance bottlenecks may occur, resulting in slower data processing or software crashes. There are also problems such as weak three-dimensional display function, poor data transferability, and low accuracy of calculation results, which are difficult to meet the increasing requirements of large-scale construction and infrastructure projects at home and abroad. In addition, both BIM software and non-BIM software are inconvenient when calculating ultra-deep and ultra-wide quantities. For BIM software, the calculation of ultra-deep or ultra-wide quantities requires additional modeling of ultra-deep and ultra-wide surfaces, and it is impossible to directly use existing data resources for calculation, which will generate a large amount of additional workload and affect the time cost and resource allocation of the project. Non-BIM software needs to combine external Excel calculation tables to extract multiple indirect parameters for calculation, and the accuracy of the results is not high. In addition, it is difficult to promote dredging quantities based on national standards in overseas projects, because the calculation methods based on national standards are all in Chinese and cannot be widely used in foreign projects. A lot of repetitive text translation work is required, and it is impossible to directly generate an English version of the engineering quantity table. Summary of the invention

[0004] The present invention overcomes the defects of the prior art and provides a method for calculating the quantity of dredging engineering in waters of a water transport engineering based on BIM technology.

[0005] To achieve the above-mentioned purpose, the present invention provides a method for calculating the quantity of dredging works in water transport engineering based on BIM technology, comprising:

[0006] Model the target dredging project based on BIM technology to obtain the target dredging project model, and number the modeling areas to distinguish them, read the data through the target dredging project model, and obtain the data reading information;

[0007] Obtaining geological conditions and available construction equipment resources of the target dredging project, selecting the type of dredger, screening the over-depth value and over-width value according to the selected dredger type, and obtaining the first analysis information;

[0015] Wherein, ΔH is the ultra-deep value, S 开挖区域底三维阴影面积 is the bottom area of ​​dredging excavation range, V 超深 For ultra-deep engineering;

[0016] The calculation formula of the extra-wide engineering quantity is as follows:

[0017]

[0018] Among them, the V 超宽 For extra-wide engineering, the S 边坡三维阴影面积 is the three-dimensional curved surface area of ​​the slope, ΔB is the extra width value, ΔH is the extra depth value, m is the designed slope ratio, L 边坡坡脚周线长 It is the perimeter length of the slope toe.

[0019] In this scheme, the over-excavation volume is the sum of the over-depth volume and the over-width volume.

[0020] In this scheme, the calculation method of the siltation engineering quantity during the construction period is as follows:

[0021] The calculation formula for the amount of siltation during the construction period is as follows:

[0022] V 施工期回淤 =S 开挖区域底三维阴影面积 * Construction period backfill speed * Construction period,

[0023] Among them, the V 施工期回淤 is the siltation volume during the construction period, S 开挖区域底三维阴影面积 is the bottom three-dimensional shadow area of ​​the excavation area.

[0024] In this solution, the water area dredging project summary table can be exported to an English version by setting an English version header.

[0025] In this solution, the dynamic update mechanism is specifically set to adopt a link format and retain the calculation formula in the cell to dynamically link the calculation formula and the extracted data.

[0026] The second invention of the present invention also provides a computer-readable storage medium, characterized in that the computer-readable storage medium includes a method program for counting the quantity of dredging engineering works in water areas of water transport projects based on BIM technology, and when the method program for counting the quantity of dredging engineering works in water areas of water transport projects based on BIM technology is executed by a processor, the steps of the method for counting the quantity of dredging engineering works in water areas of water transport projects based on BIM technology as described in any one of the above items are implemented.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0040] Figure 1 A flow chart of a method for calculating the quantity of dredging works in waters of a water transport project based on BIM technology provided by one embodiment of the present invention;

[0041] like Figure 1 As shown, the present invention provides a flow chart of a method for statistically analyzing the dredging quantity of water transport engineering waters based on BIM technology, including:

[0042] S102, modeling the target dredging project based on BIM technology to obtain a target dredging project model, numbering and distinguishing the modeling areas, and reading data through the target dredging project model to obtain data reading information;

[0043] S104, obtaining geological conditions and available construction equipment resources of the target dredging project, selecting a dredger type, screening the over-depth value and over-width value according to the selected dredger type, and obtaining first analysis information;

[0044] S106, combining the data reading information and the first analysis information, calculating the over-depth engineering quantity, over-width engineering quantity, over-excavation quantity and construction period siltation engineering quantity based on preset calculation rules, editing and generating a water area dredging engineering summary table according to the calculation results, and exporting the table;

[0045] S110, setting a dynamic update mechanism, when the BIM model is modified or updated, the water area dredging project summary table is automatically updated through the dynamic update mechanism.

[0046] Furthermore, in a preferred embodiment of the present invention, the modeling areas are numbered and distinguished, specifically by grouping the slopes according to the classified statistical engineering quantity requirements.

[0047] Furthermore, in a preferred embodiment of the present invention, the data is read through the target dredging project model to obtain data reading information, which specifically includes the three-dimensional surface area of ​​the slope, the circumference length of the slope toe, and the designed slope ratio.

[0048] It should be noted that the basic data required for subsequent calculations are read based on the model, including the three-dimensional surface area of ​​the slope, the perimeter length of the slope toe, the designed slope ratio, etc., and stored for use in the next step.

[0049] It should be noted that, in the present invention, the geological conditions and available construction equipment resources of the target dredging project are obtained, the dredger type is selected, and the over-depth value and over-width value are screened according to the selected dredger type, wherein the over-depth value and over-width value are screened by the built-in relevant numerical values ​​in Table 7.2.3 of "JTS181-5-2012 Design Code for Dredging and Filling Engineering".

[0050] Furthermore, in a preferred embodiment of the present invention, the calculation method of the super-depth engineering quantity and the super-width engineering quantity specifically includes:

[0051] The calculation formula for the ultra-deep engineering quantity is as follows:

[0052] V 超深 =S 开挖区域底三维阴影面积 *ΔH,

[0053] Wherein, ΔH is the ultra-deep value, S开挖区域底三维阴影面积 is the bottom area of ​​dredging excavation range, V 超深 For ultra-deep engineering;

[0054] The calculation formula of the extra-wide engineering quantity is as follows:

[0055]

[0056] Among them, the V 超宽 For extra-wide engineering, the S 边坡三维阴影面积 is the three-dimensional curved surface area of ​​the slope, ΔB is the extra width value, ΔH is the extra depth value, m is the designed slope ratio, L 边坡坡脚周线长 It is the perimeter length of the slope toe.

[0057] Furthermore, in a preferred embodiment of the present invention, the over-excavation volume is the sum of the over-depth volume and the over-width volume.

[0058] Furthermore, in a preferred embodiment of the present invention, the calculation method of the siltation engineering quantity during the construction period is specifically as follows:

[0059] The calculation formula for the amount of siltation during the construction period is as follows:

[0060] V 施工期回淤 =S 开挖区域底三维阴影面积 * Construction period backfill speed * Construction period,

[0061] Among them, the V 施工期回淤 is the siltation work volume during the construction period, S 开挖区域底三维阴影面积 is the bottom three-dimensional shadow area of ​​the excavation area.

[0062] It should be noted that the siltation speed during the construction period is determined by referring to the hydrological conditions of the specific project. At the same time, referring to the "General Design Code for Seaports", the general siltation depth is taken as 0.3~0.5m, and the siltation volume during the construction period is finally calculated.

[0063] Furthermore, in a preferred embodiment of the present invention, the water area dredging project summary table can be exported into an English version table by setting an English version header.

[0064] It should be noted that the summary table of water dredging projects includes common information such as low elevation dredging in each area, three-dimensional shadow area at the bottom of the dredged excavation area (i.e. grid calculated excavation volume), slope excavation volume, super-deep and super-wide project volume, and siltation volume during the construction period.

[0065] It should be noted that in the export process, the table can be exported as a "table" object and inserted into the BIM software model space, or it can be exported to .xls format, which can be opened with the corresponding format document software. You can choose to export the English version of the table. Numerical calculations are based on the extraction of numerical values ​​combined with formula calculations, so you only need to set the English version of the table header to achieve this function, effectively reducing the corresponding translation workload in the later stage.

[0066] Furthermore, in a preferred embodiment of the present invention, the dynamic update mechanism is specifically set to adopt a link format and retain the calculation formula in the cell to dynamically link the calculation formula and the extracted data.

[0067] It should be noted that the calculation formula and extracted values ​​in the table are dynamically linked. The table uses a link format and retains the calculation formula in the cell. When the BIM model is modified or updated, the system and the table can automatically update the corresponding values ​​and display results, realize the dynamic link relationship of the values, and keep dynamic updates at all times.

[0068] Figure 2 A schematic diagram of engineering calculation quantity provided by an embodiment of the present invention, Figure 3 A schematic diagram of an ultra-deep and ultra-wide cross section provided by an embodiment of the present invention, Figure 4 An ultra-wide cross-sectional exploded view provided for one embodiment of the present invention.

[0069] Furthermore, since the design engineering quantity of the dredging project should include the design section engineering quantity, the calculation of the over-depth and over-width engineering quantity, and the construction period siltation engineering quantity calculated according to natural conditions and the construction period, the present invention is Figure 2 An illustration of the engineering calculation quantities is given.

[0070] Among them, "ΔB overwidth" and "ΔH overdepth" are specific concepts relative to the design standards. They are to consider the horizontal and vertical deviations of dredging operations, and to increase the calculated overwidth and calculated overdepth in width and depth respectively. The calculated overwidth and calculated overdepth values ​​are related to the type and specification of the construction dredger, which can be understood from Table 7.2.3 in "JTS181-5-2012 Design Code for Dredging and Filling Engineering".

[0071] Furthermore, since the calculation of the super-deep engineering volume and the super-wide engineering volume is relatively complex and needs to be combined and decomposed, the present invention Figure 3 Display ultra-deep and ultra-wide sections, through Figure 4 Shows an extra-wide section breakdown.

[0072] exist Figure 3 In the calculation, the ultra-depth value is the green shaded area shown in the figure (i.e. the volume in three dimensions), and the ultra-width value is the magenta shaded area in the figure. Figure 3 The red shaded part is decomposed to obtain Figure 4 .

[0073] exist Figure 4 The calculated extra width is the area of ​​the red part in the figure (S CgdD ), the area of ​​the green shaded part (S Cecg ).

[0074] Thus from Figure 4 From this we can learn:

[0075] V 超宽 =S CgdD *L hg +S Cefg *L 边坡坡脚周线长 -S cfg *L 边坡坡脚周线长 ,

[0076] Transform the above formula to get:

[0077]

[0078] Among them, the V 超宽 For extra-wide engineering, the S 边坡三维阴影面积 is the three-dimensional curved surface area of ​​the slope, ΔB is the extra width value, ΔH is the extra depth value, m is the designed slope ratio, L 边坡坡脚周线长 It is the perimeter length of the slope toe.

[0079] It should be noted that ΔB and ΔH are related to the selected dredging equipment, which can be found in Table 7.2.3 of "JTS181-5-2012 Design Specifications for Dredging and Filling Engineering". The design slope ratio is determined by the designer based on the geological and project conditions.

Figure 6 A schematic diagram of the name attributes of a triangulated surface provided by an embodiment of the present invention, Figure 7 A schematic diagram of the minimum elevation attribute of a triangulated surface provided by an embodiment of the present invention.

[0081] Further, by Figure 5 It can be learned that:

[0082] The first column is the broad name of the dredging project: input according to engineering practices and the function of the area, providing drop-down selection and custom input, including anchoring waters, connecting waters, turning waters, waterways, etc.

[0083] The second column is the subdivision area or serial number: it can be divided according to different geological divisions, different dredging low elevation divisions, or different slope ratio divisions, in order to improve the accuracy and comparability of statistical engineering quantities. Set to read the "name" of a specific "triangulated surface" object, such as Figure 6 shown.

[0084] The third column is the dredging area low elevation: the minimum low elevation value of the area, which is set to read the "minimum elevation" of a specific "TIN surface" object, such as Figure 7 shown.

[0085] The fourth column is the mesh calculation excavation volume, that is, the excavation volume between the original terrain of the corresponding software and the bottom excavation model of the designed surface. It is set to read the "Cut" (or Fill) volume in the "Volume Panel" of a specific "Triangulated Surface" object.

[0086] The fifth column is the slope amount, which is the amount of cut between the original terrain of the corresponding software and the slope grading model of the designed surface. It is set to read the "cut" (or fill) amount in the "Volume Panel" of a specific "Triangulated Surface" object.

[0087] The sixth column is the amount of super-deep and super-wide projects, which is the value calculated by the above-mentioned calculation method for super-deep and super-wide dredging projects. The calculation is based on the built-in calculation formula and the values ​​read by some models.

[0088] The seventh column is the amount of siltation during the construction period, which is calculated comprehensively based on the excavation area (this value can be obtained by reading the model information) and the annual siltation amount obtained by the user based on relevant hydrological conditions.

[0089] The eighth column is the numerical statistics of each row, which is the sum of "grid calculated excavation volume" + "slope volume" + "extra-deep and extra-wide engineering volume" + "backfilling during construction period" of each row.

[0090] The present invention provides a method for calculating the quantity of dredging works in water transport engineering areas based on BIM technology, thereby achieving the following beneficial effects:

[0091] (1) Filling the gap in BIM software functions: The present invention innovatively expands the application scope of BIM software, especially in key functions such as statistics of super-deep and super-excavation engineering quantities and siltation during construction, filling the gap in these specific requirements of traditional BIM software. By introducing advanced algorithms and data processing technologies, the present invention enables BIM software to handle these complex and important engineering quantity statistics tasks more accurately and efficiently, providing more comprehensive and reliable data support for the planning, design and construction management of engineering projects.

[0092] (2) Accurate results and short calculation time: Based on the BIM software platform represented by Civil 3D, and closely combined with the actual needs of domestic dredging projects, accurate statistics of key factors such as ultra-deep and ultra-excavation engineering quantities and siltation during construction are achieved. By making full use of the precise values ​​of the BIM model, the present invention effectively reduces the workload of staff in performing secondary calculations in the later stage, significantly improves the accuracy of engineering quantity statistics, and thus provides strong support for project design and budget control.

[0093] (3) Simple design, easy operation, and low difficulty in getting started: The present invention does not replace the engineering quantity calculation process of conventional BIM software, but serves as a beneficial supplement to the process. In the preliminary preparation stage, the user only needs to number and divide the calculation area; in the subsequent steps, the engineering quantities are classified, calculated, and counted according to the main attributes. The system has built-in relevant standard values, and the user only needs to select a small number of parameters according to the project specifications and actual conditions, and the system can automatically perform the calculation tasks. This design greatly simplifies the operation process and significantly reduces the learning threshold and difficulty of use for beginners and unskilled users. It not only shortens the time required to master the software operation, but also effectively improves the overall work efficiency.

[0094] (4) Setting up English version output is conducive to promoting standards and reducing translation workload: Taking into account the actual needs of overseas projects, an English version of the engineering quantity statistics table is set up. Users only need to operate one button to export the English version content, reducing the amount of repetitive work in the later stage, while also meeting the actual needs of overseas project work.
