Description

Technical Field

[0001] This invention relates to the field of municipal road construction technology, and in particular to a BIM-based municipal road construction method and system. Background Technology

[0002] Municipal road construction refers to the construction, repair, and maintenance of roads in cities or towns. It includes, but is not limited to, the laying of new roads, the renovation of old roads, and the installation and repair of underground pipelines. Municipal road construction involves not only civil engineering but also coordination of multiple professional fields, such as structural engineering, water supply and drainage systems, and electrical engineering, to ensure seamless integration of all systems and guarantee smooth traffic flow and the functionality of urban infrastructure.

[0003] In the field of municipal road construction, traditional methods rely on manual measurement or low-precision equipment to obtain geographical information, which can easily lead to inaccurate or missing data, affecting subsequent design and construction. Furthermore, traditional construction progress management relies on static plans and lacks dynamic adjustment capabilities, making it difficult to cope with emergencies and causing delays in the construction period. At the same time, the lack of effective real-time monitoring methods at the construction site makes it difficult to detect quality problems or schedule delays in a timely manner, resulting in rework and increased costs.

[0011] A multi-disciplinary coordination and conflict detection method was used to conduct cross-disciplinary collaboration and conflict detection on the 4D model to obtain a conflict-free construction plan.

[0012] By employing real-time monitoring and feedback adjustment methods, conflict-free construction plans are implemented on-site and monitored in real time, resulting in high-quality construction outcomes.

[0022] The road structural elements include the road surface, curbs, and drainage system;

[0023] For each structuring element, its geometric parameters are defined as follows:

[0024] V elem =L×W×T;

[0025] Among them, V elemLet L be the volume of the structural element, W be the length, and T be the width.

[0026] All independent structural element models are integrated with the terrain model to form a complete 3D road model.

[0027] As a preferred embodiment of the BIM-based municipal road construction method of the present invention, the step of integrating the three-dimensional road model with the time dimension using a 4D schedule planning and simulation method to obtain a 4D model includes the following specific steps:

[0028] Based on the project plan and actual needs, define the time parameters for each construction phase, expressed as follows:

[0029] T i =t i+1 -t i ;

[0030] Among them, T i t represents the duration of the i-th construction phase. i t represents the start time of this phase. i+1 This is the end time of this phase;

[0031] Specific construction tasks are assigned to corresponding time periods, and the required resources are planned. For each construction task, the required resource quantity is calculated, expressed as follows:

[0034] Using the Navisworks software tool, the time dimension T i It is integrated into the 3D road model to form a 4D model.

[0035] As a preferred embodiment of the BIM-based municipal road construction method of the present invention, the step of employing a multi-disciplinary coordination and conflict detection method to perform cross-disciplinary collaboration and conflict detection on the 4D model to obtain a conflict-free construction plan includes the following specific steps:

[0036] Create a centralized BIM platform that enables teams from different disciplines, such as structural engineering, water supply and drainage systems, and electrical engineering, to access and update project information in real time.

[0037] The design data is synchronized to the BIM platform and integrated using a unified data standard;

[0038] The distance difference between each professional element in the design data is calculated to ensure data consistency. The expression is:

[0039]

[0040] Where, Δd ij x represents the distance between the i-th professional element and the j-th professional element. i y i , z i Let x and x represent the coordinates of the i-th element in three-dimensional space. j y i , z j These are the coordinates of the j-th element in three-dimensional space;

[0041] Using the built-in conflict detection tool in BIM software, the entire 4D model is automatically scanned to identify potential spatial conflicts between different disciplines.

[0042] For each detected conflict point, record its location information and the professional elements involved;

[0043] For each point of conflict, organize cross-disciplinary teams to discuss and develop solutions;

[0044] When it is found that water supply and drainage pipes intersect with electrical wiring, the conflict can be avoided by adjusting the installation path of one of the systems.

[0045] As a preferred embodiment of the BIM-based municipal road construction method of the present invention, the specific steps of adopting a real-time monitoring and feedback adjustment method to implement and monitor conflict-free construction plans on-site and in real time to obtain high-quality construction results are as follows:

[0047] The sensors include a temperature sensor, a humidity sensor, and a displacement sensor;

[0048] Establish a data transmission channel using Internet of Things (IoT) technology;

[0049] Within the central control system, the received data is analyzed in real time to assess whether the current construction status meets expectations;

[0050] When any deviation from the planned construction scheme is discovered, the feedback mechanism is activated, and corresponding adjustment strategies are formulated based on the degree of deviation.

[0051] A comprehensive inspection of the construction quality and progress will be conducted periodically, comparing the actual completion with the planned objectives.

[0052] When quality problems or delays are discovered, corrective measures should be taken promptly.

[0053] By increasing resource input R add To speed up the process, the expression is:

[0054] R add =k×(T) expecdted -T actual );

[0055] Among them, R add The additional resources, k is the resource coefficient, and T is the amount of resources added. expected T represents the expected completion time. actual This refers to the actual completion time.

[0056] As a preferred embodiment of the BIM-based municipal road construction method of the present invention, the step of using a completion acceptance and maintenance plan method to conduct final inspection and data archiving of high-quality construction results to obtain complete project records and subsequent maintenance plans includes the following specific steps:

[0057] After all construction activities are completed, an acceptance team composed of the owner, designer and supervising engineer will be organized to conduct a comprehensive quality inspection of the entire project.

[0058] Any defects or non-compliance with design standards discovered during quality inspection should be immediately recorded, and detailed corrective measures should be developed.

[0059] All relevant documents throughout the entire project lifecycle will be systematically organized and archived in a unified standard format.

[0074] Figure 2 This is a schematic diagram of the BIM-based municipal road construction system in Example 1. Detailed Implementation

[0075] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0076] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0077] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0078] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a BIM-based municipal road construction method, including the following steps:

[0079] S1. Data collection and preprocessing methods are used to collect geographic information and clean data from the construction site to obtain a standardized basic dataset.

[0080] Furthermore, the construction site was comprehensively scanned using a LiDAR system mounted on a drone to obtain detailed geographic information, including terrain height and surface roughness.

[0081] Outliers in the collected data were removed using statistical methods, and data gaps were filled using bilinear interpolation to obtain a standardized basic dataset.

[0082] It should be noted that by using a LiDAR system mounted on a drone for geographic information collection, not only is the speed and accuracy of data acquisition improved, but it can also cover complex terrain areas that are difficult to reach by traditional methods. By using statistical methods to remove outliers and using bilinear interpolation to fill data gaps, the integrity and consistency of the dataset are ensured, providing a solid foundation for subsequent 3D modeling.

[0083] S2. Use 3D modeling methods to construct a three-dimensional model of the standardized basic dataset to obtain a three-dimensional model of the road.

[0084] Furthermore, based on the obtained standardized baseline dataset, the Digital Elevation Model (DEM) algorithm is applied to generate the terrain surface, expressed as:

[0085] Z(x,y)=D clean (x,y)+α·sin(βx+γy);

[0086] Where Z(x,y) represents the terrain height value at position (x,y), α is an adjustment coefficient used to control the degree of fluctuation of the terrain surface, β is the horizontal frequency factor, and γ is the vertical frequency factor used to adjust the rate of change of the terrain surface waveform.

[0087] Based on the terrain model, road structure elements are added using the BIM software Revit in accordance with design specifications and requirements;

[0088] Road structural elements include pavement, curbs, and drainage systems;

[0089] For each structuring element, its geometric parameters are defined as follows:

[0090] V elem=L×W×T;

[0091] Among them, V elem Let L be the volume of the structural element, W be the length, and T be the width.

[0092] Integrate all the independent structural element models with the terrain model to form a complete 3D road model;

[0093] It should be noted that by applying the Digital Elevation Model (DEM) algorithm to generate terrain surfaces, and combining adjustment coefficients, horizontal frequency factors, and vertical frequency factors, the details and fluctuations of the terrain surface can be flexibly adjusted, making the generated terrain model more consistent with the actual situation. By adding road structure elements to the terrain model and defining the specific geometric parameters of each structure element, accurate simulation of road design can be achieved, which helps to identify potential design problems in advance and optimize design schemes.

[0094] S3. The 4D schedule planning and simulation method is used to integrate the time dimension of the road 3D model to obtain the 4D model.

[0095] Furthermore, based on the project plan and actual needs, time parameters for each construction phase are defined, expressed as follows:

[0096] T i =t i+1 -t i ;

[0097] Among them, T i t represents the duration of the i-th construction phase. i t represents the start time of this phase. i+1 This is the end time of this phase;

[0098] Specific construction tasks are assigned to corresponding time periods, and the required resources are planned. For each construction task, the required resource quantity is calculated, expressed as follows:

[0099] R j =k j ×V j ;

[0100] Among them, R j Let k be the amount of resources required for task j. j V represents the amount of resources required per unit volume for a specific task. j Let the volume of the structuring element involved in task j be .

[0101] Using the Navisworks software tool, the time dimension T i It is integrated into the 3D road model to form a 4D model;

[0102] It should be noted that by integrating the time dimension into the 3D model to form a 4D model, project managers can dynamically observe changes in construction progress in a virtual environment, identify potential time conflicts and resource bottlenecks. Dynamic simulation not only helps to develop more reasonable construction plans, but also helps to anticipate potential problems in advance, thereby taking corresponding preventive measures to reduce the risk of construction delays and cost overruns.

[0103] S4. Employ multi-disciplinary coordination and conflict detection methods to conduct cross-disciplinary collaboration and conflict detection on the 4D model to obtain a conflict-free construction plan.

[0104] Furthermore, a centralized BIM platform will be created, enabling teams from different disciplines such as structural engineering, water supply and drainage systems, and electrical engineering to access and update project information in real time.

[0105] The design data is synchronized to the BIM platform and integrated using a unified data standard;

[0106] The distance difference between each professional element in the design data is calculated to ensure data consistency. The expression is:

[0107]

[0108] Where, Δd ij x represents the distance between the i-th professional element and the j-th professional element. i y i , z i Let x and x represent the coordinates of the i-th element in three-dimensional space. j y i , z j These are the coordinates of the j-th element in three-dimensional space;

[0109] Using the built-in conflict detection tool in BIM software, the entire 4D model is automatically scanned to identify potential spatial conflicts between different disciplines.

[0110] For each detected conflict point, record its location information and the professional elements involved;

[0111] For each point of conflict, organize cross-disciplinary teams to discuss and develop solutions;

[0112] When it is found that water supply and drainage pipes intersect with electrical wiring, the conflict can be avoided by adjusting the installation path of one of the systems.

[0113] It should be noted that creating a centralized BIM platform enables teams from different disciplines to access and update project information in real time, which greatly improves the efficiency of cross-disciplinary collaboration. The platform automatically calculates the distance differences between elements of each discipline and uses built-in conflict detection tools to scan the entire 4D model, which can quickly identify and resolve potential spatial conflicts, avoid on-site rework and delays caused by design conflicts, and significantly improve the smoothness and safety of the construction process.

[0114] S5. Employ real-time monitoring and feedback adjustment methods to implement and monitor conflict-free construction plans on-site, thereby achieving high-quality construction results.

[0115] Furthermore, sensors are installed at key structural points and near underground pipelines at the construction site;

[0116] The sensors include temperature sensors, humidity sensors, and displacement sensors;

[0117] Establish a data transmission channel using Internet of Things (IoT) technology;

[0118] Within the central control system, the received data is analyzed in real time to assess whether the current construction status meets expectations;

[0119] When any deviation from the planned construction scheme is discovered, the feedback mechanism is activated, and corresponding adjustment strategies are formulated based on the degree of deviation.

[0120] A comprehensive inspection of the construction quality and progress will be conducted periodically, comparing the actual completion with the planned objectives.

[0121] When quality problems or delays are discovered, corrective measures should be taken promptly.

[0122] By increasing resource input R add To speed up the process, the expression is:

[0123] R add =k×(T) expected -T actual );

[0124] Among them, R add The additional resources, k is the resource coefficient, and T is the amount of resources added. expected T represents the expected completion time. actual This refers to the actual completion time.

[0125] It should be noted that by installing sensors at the construction site and establishing a data transmission channel through Internet of Things (IoT) technology, real-time monitoring of the construction status is achieved. The central control system analyzes the received data, promptly detects any deviations from the planned construction scheme, and initiates a feedback mechanism to formulate corresponding adjustment strategies. This ensures that the construction quality and progress remain under control. This method not only improves construction efficiency but also reduces delays caused by unforeseen problems.

[0126] S6. Use the completion acceptance and maintenance plan method to conduct a final inspection and document archiving of high-quality construction results, and obtain complete project records and post-maintenance plans.

[0127] Furthermore, after all construction activities are completed, an acceptance team composed of the owner, designer, and supervising engineer is organized to conduct a comprehensive quality inspection of the entire project.

[0128] Any defects or non-compliance with design standards discovered during quality inspection should be immediately recorded, and detailed corrective measures should be developed.

[0129] All relevant documents throughout the entire project lifecycle will be systematically organized and archived in a unified standard format.

[0135] The 3D modeling module is used to generate terrain surfaces based on a standardized base dataset using the Digital Elevation Model (DEM) algorithm. It adds road structural elements such as road surface, curbs, and drainage systems to the terrain model, defines the geometric parameters of each structural element, and integrates all independent structural element models with the terrain model to form a complete 3D road model.
