Although exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood, and the scope of the present application can be accurately conveyed to those skilled in the art.

[0071] As shown in Figure 1 , the embodiment of the present application provides a method for determining the excavation and filling quantity of a heating pipe network based on a three-dimensional model, comprising:

[0072] Step 11, obtaining topographic information of a set region and parameter data of a heating pipe network;

[0073] Step 12, establishing a three-dimensional model according to the topographic information and the parameter data;

[0074] Step 13, determining trench data, pipe data, cushion data, auxiliary facility total volume and soil data according to the three-dimensional model;

[0075] Step 14, determining total excavation volume, total filling volume and surplus soil transportation volume according to the trench data, the pipe data, the cushion data, the auxiliary facility total volume and the soil data.

[0076] In the embodiment, the method can more comprehensively and accurately reflect actual topography and pipe network layout by obtaining topographic information of a set region and parameter data of a heating pipe network to establish a three-dimensional model. The trench data, the pipe data, the cushion data, the auxiliary facility total volume and the soil data determined according to the three-dimensional model can more accurately calculate total excavation volume, total filling volume and surplus soil transportation volume, so that the calculation result is more in line with actual engineering requirements.

[0077] The method can more accurately calculate earthwork volume required by the project according to the three-dimensional model combined with soil data of different regions, so as to provide more reliable basis for engineering cost accounting and construction planning.

[0078] The method can obtain more accurate excavation and filling volume under the premise that pipe burying depth and backfill quality meet design requirements, so as to guarantee stable operation and service life of the heating pipe network and accurately calculate earthwork volume to reduce project cost.

[0079] In an optional embodiment of the present application, in the step 11, the obtaining of the topographic information of the set region and the parameter data of the heating pipe network comprises:

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

[0081] Step 112, obtaining parameter data of a heating pipe network by collecting design drawings of the heating pipe network and checking, modifying and correcting the design drawings on site,

[0082] The parameter data comprises line data, pipe parameter data and auxiliary facility parameter data of the heating pipe network.

[0083] In this embodiment, the terrain information is obtained through various means such as measuring instruments, existing data and / or remote sensing images, which can collect data from different angles and accuracy levels. Measuring instruments can directly obtain high-precision terrain data on site, accurately grasp the terrain details of key areas; existing data can provide historical terrain information and macro terrain overview as a reference and supplement; remote sensing images can display the overall terrain from a macro perspective, especially suitable for preliminary understanding of large-area terrain. The combination and verification of various methods greatly improve the accuracy and completeness of the terrain information, providing reliable basic data for subsequent three-dimensional model establishment.

[0084] Different sources of terrain information have their own advantages. High-precision data from measuring instruments can correct errors or inaccuracies in existing data and remote sensing images; existing data can guide the measurement range and focus of measuring instruments, avoiding blind measurement; remote sensing images can provide more extensive terrain information when existing data is missing or incomplete, filling in the data gaps. This complementary nature of data helps to build a more realistic and accurate terrain model, thereby more accurately calculating the excavation and filling volume.

[0085] By collecting parameter data from the design drawings of the heating pipe network, and based on the design plan, the normativity and systematicness of the parameter data are ensured. The design drawings record key information such as pipe network line data, pipe parameter data and auxiliary facility parameter data, providing clear guidance and basis for engineering construction.

[0086] On-site investigation and modification of design drawings ensure that parameter data closely match actual conditions. In actual engineering, there may be differences between the site conditions and the design drawings, such as underground obstacles and terrain changes. Through on-site investigation, these problems can be discovered in time and the design drawings can be modified, avoiding engineering errors or changes due to design discrepancies with reality. This combination of design drawings and on-site investigation ensures the reliability of pipe network parameter data, improving the feasibility and safety of the project.

[0087] Clearly indicating that parameter data includes pipe network line data, pipe parameter data and auxiliary facility parameter data makes data collection and management clearer and more organized. In the engineering implementation process, each participant can clearly understand the parameter information that needs to be obtained and focused on, avoiding data omission or confusion, improving work efficiency and data processing accuracy. At the same time, it also provides clear guidance for subsequent three-dimensional model establishment, excavation and filling volume calculation based on these parameter data, ensuring that each link of the project is based on accurate and complete data.

[0093] Step 125, integrating the terrain model, the line model of the heat supply pipe network, the pipe model and the auxiliary facility model to form a complete three-dimensional model.

[0124] In the step 1451, the volume of filling is determined according to V x = V a -V b -V c -V d

[0125] ​​​​Among them, V x V is the fill volume. a V represents the total excavation volume of all individual trench sections. b V is the volume of the pipe. c V is the volume of the cushion layer. d This refers to the total volume of the ancillary facilities.
