Description

Method for Rapid Creation of BIM Model of High-Pile Wharf Technical Field

[0001] The present invention relates to a method for creating a BIM model, and more particularly to a method for quickly creating a BIM model of a high-pile wharf. Background Art

[0002] In recent years, with the widespread development of BIM technology, it has played an increasingly important role in the water transport engineering industry. As one of the most widely used types of wharf structures, high-pile wharves have led some companies to create numerous BIM models for these structures using BIM modeling software. Currently, the primary method for creating BIM models for high-pile wharves is still based on a drawing-based modeling approach. This approach utilizes individual components within the high-pile wharf as building blocks, assembling these components spatially to create a complete model. The drawbacks of this approach are that it adds a step of drawing-based modeling, which not only increases labor and time costs, but also, because the components in the drawings primarily contain geometric information, the resulting BIM models lack non-geometric attribute information, making them unsuitable for specific phases and hindering their subsequent use. Furthermore, when a component within the BIM model needs to be adjusted, it often requires more than just modifying that component; it also requires modifying its associated components. This extensive process, involving the spatial relationships of the entire high-pile wharf model, is prone to errors and can negatively impact the usability of the high-pile wharf BIM model. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for quickly creating a BIM model of a high-pile pier. The method is mature and feasible, and can quickly and accurately create a BIM model of a high-pile pier, thereby solving the problems of creation efficiency and use efficiency of the BIM model of the high-pile pier.

[0004] The technical solution adopted by the present invention to solve the technical problem is to construct a method for quickly creating a BIM model of a high-pile wharf, including the following steps:

[0005] S1. Based on the structural characteristics of the high-pile wharf, and in accordance with design requirements and specifications, formulate the attribute information rules of the high-pile wharf BIM component model unit;

[0006] S2. Create a BIM component model of the high-pile wharf according to the rules established in step S1;

[0007] S3, assembling the component models created in step S2 on the horizontal bent plane of the high-pile wharf;

[0008] S4. For each component model on the horizontal rack plane, coupling the horizontal rack plane position logic relationship is performed;

[0009] S5. Use the created transverse bents as basic units to build the BIM structural segment model of the high-pile wharf.

[0010] S6. For each transverse bent model in the assembled structural segment model, coupling is performed on the longitudinal position logic relationship of the high-pile wharf; the longitudinal position logic relationship of the high-pile wharf structural segment model includes the longitudinal distance spacing and alignment relationship between all transverse bent models at the longitudinal position of the high-pile wharf, as well as the linkage relationship between the bents;

[0011] S7, combining and connecting the multiple structural segment models coupled in step S6 in the longitudinal position of the high-pile wharf, copying and adjusting the positions as needed, and gradually building the overall model of the high-pile wharf;

[0012] S8. For each structural segment model in the assembled overall model, the longitudinal position logic relationship of the high-pile pier is coupled; the longitudinal position logic relationship of the overall model of the high-pile pier includes the longitudinal distance spacing and alignment relationship between all structural segment models at the longitudinal position of the high-pile pier and the coupling between the structural segments.

[0013] According to the above solution, in step S1, the BIM component model of the high-pile wharf includes beams, piles, panels, surface layers, mooring components and auxiliary facilities component families;

[0014] According to the above scheme, the attribute rules include the standard format definition of the geometric attributes and non-geometric attribute information of each component model of the high-pile wharf. The names of the attributes of different components are fixed according to the characteristics of different components. The non-geometric information attributes include the information attributes necessary for creating drawings and extracting engineering quantities from the model, including the standard format definition of the component's material, specifications, reinforcement information, technical requirements, and coding non-geometric attributes. The uniformity and consistency of the attribute rules ensure that the attribute rules of different component models are consistent in format definition, so that they can be uniformly processed and managed throughout the entire model creation process. At the same time, the attribute rules can be expanded and adjusted according to actual needs to adapt to the needs and characteristics of the project.

[0015] According to the above solution, in step S2, the component model includes beams, piles, panels, surface layers, berthing components and ancillary facilities components. Before creating the overall model, the high-pile wharf BIM component model is pre-loaded into the modeling software so that the high-pile wharf BIM component model can be directly used and referenced during the modeling process.

[0016] According to the above scheme, in step S3, the component model is vertically based on the dock surface elevation reference point, and the component model is horizontally based on the dock front line as the reference point, and beams, pile foundations, longitudinal beams, prefabricated panels, surface layers, and ancillary facilities are placed in sequence to form a complete high-pile dock transverse frame.

[0017] According to the above scheme, in step S4, the logical relationship of the plane position of the dock transverse rack includes the horizontal distance spacing, the upper and lower distance spacing and the alignment relationship between all component models on the plane where the transverse rack is located, as well as the linkage relationship between the component models; in the vertical direction, the top elevation of the pile foundation is coupled with the bottom elevation of the beam, the top elevation of the beam and the top elevation of the longitudinal beam, the bottom elevation of the precast panel and the top elevation of the transverse and longitudinal beams, the top elevation of the cast-in-place surface layer and the dock surface elevation, the bottom elevation of the mooring bollard and the dock surface elevation, and the top elevation of the berthing component and the bottom elevation of the beam; in the horizontal direction, the fender position is coupled with the dock front line, the front side beam position is coupled with the dock front line, the rear side beam position is coupled with the beam, and the position of the ancillary facilities is coupled with the dock front line in the horizontal direction.

[0018] According to the above solution, in step S5, a plurality of transverse bent frame models are combined and connected in the longitudinal position of the high-pile wharf, copied and adjusted in position as needed, and the structural segment model of the high-pile wharf is gradually constructed.

[0019] According to the above scheme, in step S6, in the longitudinal direction of the high-pile wharf, the longitudinal beam length is coupled to the frame spacing, the number of longitudinal beams is coupled to the number of frames, the panel length is coupled to the frame spacing, the number of panels is coupled to the number of frames, and the length of the cast-in-place surface layer is coupled to the length of the structural segment. The created structural segment model is used as the basic unit to build the overall BIM model of the high-pile wharf.

[0020] According to the above scheme, logical relationship coupling is implemented on the model, and parametric modeling is adopted; the logical relationship coupling of the horizontal rack is to couple the logical relationship between the component and the plane position of the rack, the logical relationship coupling of the structural segment model is to couple the logical relationship between the rack model and the longitudinal position of the wharf, and the logical relationship coupling of the overall model is to couple the logical relationship between the structural segment model and the longitudinal position of the wharf.

[0021] The method for quickly creating a high-pile wharf BIM model according to the present invention has the following beneficial effects:

[0022] The BIM model creation method for high-pile wharf proposed in the present invention builds a structural segment model with the horizontal racks of the high-pile wharf as the basic building unit, and builds an overall model with the structural segment model as the building unit, thereby realizing the convenient and accurate construction of the BIM model of the high-pile wharf, which conforms to the engineering design habits of engineering designers. The completion of model construction means the completion of engineering design, which greatly reduces the modeling workload of engineering designers, and also reduces the workload of adjusting and modifying the model. It has high engineering applicability, can greatly improve the accuracy, cost and efficiency of the BIM model creation of the high-pile wharf, and has obvious promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0024] FIG1 is a flow chart of a method for quickly creating a BIM model of a high-piled wharf according to the present invention. DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0026] As shown in FIG1 , the method for quickly creating a high-pile wharf BIM model of the present invention includes the following steps:

[0027] S1. Based on the structural characteristics of high-pile piers, and in accordance with design requirements and specifications, formulate attribute information rules for the BIM component model units of high-pile piers; the BIM component model of high-pile piers includes beams, piles, panels, surface layers, berthing components and ancillary facilities component families; attribute rules include the standard format definition of geometric attributes and non-geometric attribute information of each component model of high-pile piers; non-geometric information attributes include information attributes required for creating drawings and extracting engineering quantities from the model.

[0028] S2. Create BIM component models for all high-pile wharf components according to the rules established in step S1. These component models include beams, piles, panels, surface layers, mooring components, and ancillary facilities components. Before creating the overall model, these component models are pre-loaded into the modeling software so that they can be directly used and referenced during the modeling process.

[0029] S3. Assemble the component models created in step S2 on the horizontal bent plane of the high-pile wharf. Vertically, using the wharf surface elevation as a reference point, and horizontally, using the wharf front line as a reference point, place the beams, pile foundations, longitudinal beams, precast panels, surface layers, and ancillary facilities in sequence, ultimately forming a complete horizontal bent plane of the high-pile wharf. During assembly, pay attention to the angle and position of the component models in both directions of the horizontal bent plane.

[0030] S4. For each component model on the horizontal rack plane, couple the logical relationship of the horizontal rack plane position. The logical relationship of the horizontal rack plane position of the dock includes the horizontal distance spacing, the upper and lower distance spacing and the alignment relationship between all component models on the plane where the horizontal rack is located, as well as the linkage relationship between the component models. In the vertical direction, couple the top elevation of the pile foundation with the bottom elevation of the beam, the top elevation of the beam and the top elevation of the longitudinal beam, the bottom elevation of the precast panel with the top elevation of the horizontal and longitudinal beams, the top elevation of the cast-in-place surface layer with the dock surface elevation, the bottom elevation of the mooring post with the dock surface elevation, and the top elevation of the berthing component with the bottom elevation of the beam; in the horizontal direction, couple the fender position with the dock front line, the front side beam position with the dock front line, the rear side beam position with the beam, and the position of the ancillary facilities with the dock front line in the horizontal direction.

[0031] S5. Build the BIM structural segment model of the high-piled wharf using the created transverse bents as basic units. Combine and connect multiple transverse bent models along the longitudinal axis of the high-piled wharf, copying and repositioning them as needed to gradually construct the structural segment model. This step primarily determines the required transverse bent pattern, the spacing between bents, the number of bents, the pile torsion angles, and the fender pattern between bents.

[0032] S6. For each transverse bent model in the assembled structural segment model, the longitudinal position logic of the high-pile wharf is coupled. The longitudinal position logic of the high-pile wharf structural segment model includes the longitudinal spacing and alignment relationships between all transverse bent models in the longitudinal position of the high-pile wharf, as well as the linkage relationship between bents. In the longitudinal direction of the high-pile wharf, the longitudinal beam length is coupled with the bent spacing, the number of longitudinal beams is coupled with the number of bents, the panel length is coupled with the bent spacing, the number of panels is coupled with the number of bents, and the length of the cast-in-place surface layer is coupled with the structural segment length. The created structural segment models serve as the basic units to build the overall BIM model of the high-pile wharf.

[0033] S7: Combine and connect the multiple structural segment models coupled in step S6 along the longitudinal direction of the high-pile wharf, copy and adjust their positions as needed, and gradually construct the overall model of the high-pile wharf. This step mainly determines the required structural segment style, number of structural segments, and structural joint width.

[0034] S8. For each structural segment model in the assembled overall model, couple the longitudinal position logic of the high-pile pier. The longitudinal position logic of the overall high-pile pier model includes the longitudinal spacing and alignment relationships between all structural segment models in the longitudinal position of the high-pile pier, as well as the coupling between structural segments. In the longitudinal direction of the high-pile pier, couple the pier length with the number of structural segments and the width of the structural joints.

[0035] Designers can use the transverse frame model to arbitrarily build the structural segment model, and use the structural segment model to arbitrarily build the overall model; after completing the creation of the high-pile wharf BIM model, adjusting the transverse frame model can automatically complete the adjustment of the structural segment model and the overall model.

[0036] The method for rapidly creating a high-pile wharf BIM model, presented in this paper, constructs a high-pile wharf transverse frame model from individual component models, then constructs a high-pile wharf structural segment model from the transverse frame model, and finally constructs the overall wharf model from the structural segment model. This process enables rapid assembly of the high-pile wharf BIM model. The goal is to combine the high-pile wharf design process with the high-pile wharf BIM modeling process, transforming the spatial coupling relationship between components into a coupling relationship between the high-pile wharf transverse frames and structural segments, and between the structural segments and the overall model, thereby addressing issues such as slow modeling speed, difficulty in model modification, and low automation.

[0037] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
