[0017] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification.

On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] The technical solution of the present invention can be simplified into a design part and an optimization part, wherein the design part and the optimization part are both completed automatically, and both the design and optimization processes require the use of construction parameters, which include geometric parameters, material parameters and mechanical parameters.

[0021] in, The geometric parameters are defined as: Building distribution: describes the location layout of buildings within the site, including the spacing between buildings, distance from the site boundary, etc.

[0022] Building size: including the length, width, height of the building, the height of each floor, the span and depth of the rooms, etc.

[0023] Dimensions of structural components: such as cross-sectional dimensions of beams, columns, and slabs.

[0024] The material parameters are defined as: Concrete parameters, component material parameters, masonry material parameters.

[0025] The mechanical parameters are defined as: Soil parameters, structural load parameters: including permanent loads and variable loads. These load parameters are important bases for internal force analysis and structural safety verification during structural design and construction. For example, during roof construction, it is necessary to consider the impact of snow loads on the roof structure and reasonably design the roof slope and the thickness of the roof panel.

[0026] The above construction parameters can be used to construct a BIM model that can truly reflect the construction area, and the BIM model can be used to achieve preliminary design and optimization of the structure of the pipeline network.

[0027] Figure 1 A schematic flow chart of a BIM-based pipeline design method disclosed in an embodiment of the present invention is shown, comprising the following steps: S1, constructing a first pipeline network structure according to construction parameters.

[0030] Generating the first pipeline network structure also includes dividing the pipeline into a plurality of standard pipe segments and customized pipe segments.

[0031] The above-mentioned standard pipe section is defined as: a pipe section using standard parts. Standard parts are commercially available products with fixed specifications and can be used as soon as they are purchased.

[0032] The above-mentioned customized pipe section is defined as: a pipe section using customized parts, and the customized parts need to be customized in the factory.

[0033] The advantage of using standard pipe sections is that it can save design and procurement costs, and the cost of use is low compared to customized parts.

[0034] The benefit of using custom pipe sections is the stability of use under specific conditions, such as stress concentration areas and dynamic load areas.

[0035] The standard pipe sections and customized pipe sections in the above-mentioned first pipeline network structure are designed according to preset requirements. For example, if the set requirement is to prioritize performance, more customized pipe sections are used; if the set requirement is to prioritize cost, more standard pipe sections are used. Among them, the structure of the standard pipe sections and customized pipes in the first pipeline network structure is a reference structure and can be adjusted.

[0036] S2, using the construction parameters and the prediction parameters as test parameters to perform structural detection on the first pipeline network structure.

[0038] In one example, one of the functional areas serves as a parking area, and will have dynamic loads of vehicles and people during its future use. The dynamic load of the functional area is calculated based on the predicted vehicle and passenger flow.

[0039] In another example, if the function of one of the functional areas is leisure, it will have dynamic loads of people during its future use. The dynamic load of the functional area is calculated based on the predicted flow of people.

[0040] The process of performing structural inspection on the first pipeline network structure includes: S25, importing the construction parameters and the prediction parameters into the BIM model respectively; S26, performing simulation analysis respectively to obtain two sets of test data; The test data acquisition process includes: S261, obtaining soil parameters of each pipe section in the first pipeline network structure from the construction parameters, including soil type, stratification, and mechanical parameters; S262, constructing a simulation environment and importing construction parameters and prediction parameters respectively; S263, meshing the model, generating a finite element mesh, and solving the simulation model; S264, obtain the size and distribution of soil load and dynamic load on the pipeline, as well as the stress, strain and displacement of the pipeline.

[0041] S27, using the set screening threshold to identify abnormal parameters from the two groups of test data respectively.

[0042] According to the set screening threshold, the stress, strain and displacement of the pipeline are identified and the abnormal parameters are extracted.

[0043] S3, obtaining parameters generated during the first pipeline network structure detection process, and writing abnormal parameters into an abnormal data list.

[0044] S4, adjusting the first pipeline network structure according to the abnormal data list, and repeating the above structure detection, if there are abnormal parameters, continue to adjust until there are no abnormal parameters.

[0045] Adjusting the first pipeline network structure includes adjusting the construction position of the first pipeline network structure; and adjusting the number, position and size of standard pipe segments and customized pipe segments on the first pipeline network structure.

[0046] The purpose of the above adjustment is to adjust the above content according to the location and parameter value of the abnormal parameter, so that each pipe section on the pipeline network structure can operate stably in the subsequent use process.

[0047] S5, outputting the pipeline network structure without abnormal parameters as the second pipeline network structure.

[0048] Among them, the second pipeline network structure is the final output structure.

[0049] The second pipeline network structure is composed of standard pipe sections and customized pipe sections, which can improve the stability during use.

[0050] Customized pipe sections can also be customized according to the construction environment. Specifically, according to the installation environment of the area where construction is difficult, the corresponding customized pipe sections are designed in a customized manner to avoid the area where construction is difficult, improve the convenience of construction, and thus achieve the effect of improving installation efficiency.

[0052] A computer-readable storage medium stores computer instructions, wherein the computer instructions are used to enable a computer to execute the above method.
