Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of heat pipe construction, and in particular to a method and device for determining the amount of cut and fill of a heating pipe network based on a three-dimensional model. Background Art

[0002] A heating network is a type of heating system infrastructure that buries heating pipes directly underground. Cut-and-fill engineering is a crucial component of heating network construction, and its volume directly impacts project costs. Proper cut-and-fill calculation is crucial for ensuring the quality and safety of heating network projects.

[0003] Currently, the determination of cut and fill volumes for heating pipe networks based on 3D models is primarily based on on-site measurements and empirical estimates. Some methods also combine scanned terrain models with pipe network models constructed from design drawings for calculation and analysis. However, field measurements can be subject to measurement errors due to factors such as measurement tools and human factors. Empirical estimates rely primarily on the personal experience of construction workers or technicians and are highly subjective. Combining scanned terrain models with pipe network models constructed from design drawings for calculation and analysis fails to consider factors such as soil physical properties and does not fully reflect the actual project situation.

[0070] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0071] like Figure 1 As shown, an embodiment of the present invention provides a method for determining the amount of cut and fill of a heating pipe network based on a three-dimensional model, comprising:

[0072] Step 11, obtaining terrain information of a set area and parameter data of a heating network;

[0073] Step 12: establishing a three-dimensional model based on the terrain information and parameter data;

[0074] Step 13, determining trench data, pipeline data, cushion data, total volume of ancillary facilities and soil data based on the three-dimensional model;

[0075] Step 14: Determine the total excavation volume, fill volume, and excess soil transport volume based on the trench data, pipeline data, cushion data, total volume of ancillary facilities, and soil data.

[0076] In this embodiment, this method establishes a 3D model by acquiring topographic information of a designated area and parameter data for the heating network. This model more comprehensively and accurately reflects the actual topography and network layout. Based on the trench data, pipeline data, cushion data, total volume of ancillary facilities, and soil data determined by the 3D model, the total excavation volume, fill volume, and excess soil transport volume can be more accurately calculated, ensuring that the results better meet actual project requirements.

[0077] This method combines soil data from different regions based on the three-dimensional model to more accurately calculate the earthwork volume required for the project, providing a more reliable basis for project cost accounting and construction planning.

[0078] This method can obtain more accurate excavation and filling volumes while ensuring that the pipeline burial depth and backfill quality meet the design requirements. It not only ensures the stable operation and service life of the heating pipeline network, but also accurately calculates the earthwork volume to reduce the project cost.

[0079] In an optional embodiment of the present invention, in step 11, obtaining terrain information of a set area and parameter data of a heating network includes:

[0080] Step 111, obtaining topographic information of a set area through surveying instruments, existing data and / or remote sensing images;

[0081] Step 112: Obtain parameter data of the heating network by collecting design drawings of the heating network and conducting on-site inspection, verification and modification of the design drawings.

[0082] The parameter data include line data, pipeline parameter data and ancillary facility parameter data of the heating network.

[0083] In this embodiment, terrain information is acquired through a variety of methods, including surveying instruments, existing data, and / or remote sensing imagery, enabling data collection from varying angles and levels of accuracy. Surveying instruments can directly acquire high-precision terrain data on-site, accurately capturing topographic details in key areas. Existing data can provide historical terrain information and macroscopic overviews as a reference and supplement. Remote sensing imagery can provide a comprehensive overview of the terrain at a macro level, making it particularly suitable for preliminary understanding of the terrain over large areas. The integration and verification of these multiple approaches significantly improves the accuracy and completeness of terrain information, providing reliable foundational data for subsequent 3D modeling.

[0084] Different sources of terrain information each have their own advantages. High-precision data from surveying instruments can correct errors or inaccuracies in existing data and remote sensing imagery. Existing data can guide the scope and focus of surveying instruments, avoiding blind measurements. Remote sensing imagery can provide more extensive terrain information and fill data gaps when existing data is missing or incomplete. This complementary data structure helps construct more realistic and accurate terrain models, thereby more accurately calculating cut and fill volumes.

[0085] By collecting parameter data from design drawings of the heating network, and basing the design plan on it, we ensured the standardization and systematic nature of the parameter data. The design drawings detailed key information such as the network's route data, pipeline parameters, and ancillary facility parameters, providing clear guidance and basis for project construction.

[0086] On-site inspections, verifications, and modifications to design drawings ensure that parameter data closely matches actual conditions. In actual projects, site conditions may differ from design drawings, such as underground obstacles or terrain variations. On-site inspections can promptly identify these issues and allow revisions to the design drawings, avoiding project errors or changes caused by discrepancies between design and actual conditions. This combined approach of design drawings and on-site inspections ensures the reliability of pipeline network parameter data and improves project feasibility and safety.

[0087] The explicit specification of parameter data, including heating network line data, pipeline parameter data, and ancillary facility parameter data, makes data collection and management clearer and more organized. During project implementation, all parties involved clearly understand the parameter information they need to obtain and focus on, avoiding data omissions or confusion, improving work efficiency and data processing accuracy. It also provides clear guidance for subsequent work such as 3D modeling and cut-and-fill volume calculations based on this parameter data, ensuring that every aspect of the project is based on accurate and complete data.

[0088] In an optional embodiment of the present invention, in step 12, establishing a three-dimensional model based on terrain information and parameter data includes:

[0089] Step 121, creating a terrain model based on the terrain information;

[0090] Step 122: drawing a line model of the heating pipe network on the terrain model according to the line data of the heating pipe network;

[0091] Step 123: creating a pipeline model on the line model of the heating network according to the pipeline parameter data;

[0092] Step 124: creating an auxiliary facility model on the line model of the heating network according to the auxiliary facility parameter data;

[0093] Step 125 , integrating the terrain model, the line model of the heating network, the pipeline model and the ancillary facilities model to form a complete three-dimensional model.

[0094] In this embodiment, the terrain model is created, the line model is drawn, the pipeline model is created, the auxiliary facilities model is created, and the model is integrated. Each step is modeled based on specific information and objects, ensuring the accuracy of the model. This can maximize the restoration of the actual project situation and improve the accuracy of the model.

[0095] The terrain, lines, pipelines, and ancillary facilities were modeled separately and then integrated into a complete 3D model, comprehensively covering all elements of the heating network project. This completeness allows the model to more fully demonstrate the actual project conditions, providing a more reliable basis for subsequent cut and fill calculations and engineering analysis, avoiding calculation errors or incomplete analysis caused by missing model elements.

[0102] This example provides detailed steps for determining trench data, pipeline data, cushion data, total volume of ancillary facilities, and soil data. The specific content of each data item and the method for extracting it from the 3D model are clearly defined. This makes the data extracted from the 3D model more accurate, avoids ambiguity and uncertainty, and provides a reliable data foundation for subsequent calculations such as cut and fill volumes.

[0103] Determining this data through a 3D model leverages its accuracy and completeness. The 3D model integrates topographic information and pipeline network parameter data, more accurately reflecting actual project conditions, reducing data errors and improving data reliability, thereby making engineering analyses and decisions based on this data more credible.

[0124] Step 1451, according to V x =V a -V b -V c -V d Determine the fill volume,

[0125] Among them, V x is the fill volume, V a is the total excavation volume of all single-segment trenches, V b is the volume of the pipe body, V c is the volume of the cushion, V d is the total volume of ancillary facilities.

[0130] Among them, V z is the amount of surplus soil transported outward, V y is the excavation volume in loose state, V x is the fill volume.

[0131] In this example, the excavation volume of each single trench section is determined, and then the total excavation volume, the pipe volume, the cushion volume, and other parameters of all single trench sections are calculated. Finally, the fill volume and the amount of excess soil to be transported are determined. This rigorous calculation process reduces the possibility of errors.

[0132] Comprehensive consideration is given to various information including trench data, pipeline data, cushion data, total volume of ancillary facilities and soil data, ensuring that the calculation results can accurately reflect the actual project conditions.

[0133] Accurately calculating the total excavation volume, fill volume, and the amount of excess soil transported can rationally arrange earthwork allocation and estimate the workload and cost of excess soil transportation. This helps optimize construction plans, improve project management efficiency, and avoid problems such as increased costs or construction delays caused by inaccurate earthwork volume calculations.

[0134] The soil looseness coefficient was introduced when calculating the amount of surplus soil to be transported out, taking into account the change in volume of the soil in a loose state after excavation, making the calculation results more in line with the actual situation, further improving the accuracy and practicality of the calculation, and helping to more reasonably plan earthwork transportation and stacking.

Clarify the scope of parameter data to streamline data collection and management, improve work efficiency and data processing accuracy, and provide accurate and complete data for subsequent engineering steps.

[0137] The steps of creating terrain models, drawing line models, creating pipeline models, creating ancillary facilities models, and integrating models are targeted at specific information and objects to ensure model accuracy and restore the actual project conditions to the greatest extent possible.

[0138] The terrain, lines, pipelines and ancillary facilities are modeled separately and then integrated to comprehensively cover all elements of the heating pipe network project. This can more comprehensively display the actual situation of the project, provide a more reliable basis for excavation and filling volume calculation, engineering analysis, etc., and avoid calculation errors or incomplete analysis due to missing model elements.
