[0002] Land development refers to the planning, design, and construction of a vacant plot of land for the construction of various types of factory buildings. In modern society, factory buildings support the operations of enterprises in various sectors, including industry, commerce, and services, providing space for production, processing, warehousing, logistics, and office management. The primary task in land development for factory buildings is rational planning and design. The planning phase considers factors such as the surrounding environment, road traffic, resource utilization, and sustainable development to formulate a targeted and flexible construction plan. The design, based on specific needs, combines safety, practicality, and aesthetics, comprehensively considering functional area distribution, building structure, personnel flow, fire protection equipment, drainage systems, and other aspects to ensure the factory buildings meet the expected usage objectives. Construction is the crucial stage in transforming the construction plan into an actual factory building. The construction process involves site selection, land leveling, foundation treatment, main building structure construction, decoration, and equipment installation. This requires coordination among multiple construction teams, material suppliers, and relevant regulatory departments to ensure the project is completed on time and complies with building codes and standards.

[0003] However, most existing civil engineering factory buildings adopt integrated construction, which results in long construction cycles, complex construction processes, and a waste of human and material resources. Summary of the Invention

[0006] This invention provides a method for constructing a modular civil engineering factory building, comprising the following steps:

[0007] S10: Construction workers construct a three-dimensional model based on the design drawings of the civil engineering plant, and then perform structural optimization on the three-dimensional model.

[0008] S20: Based on the structure and shape of the optimized three-dimensional model of the civil engineering plant, the construction personnel divide it into units to obtain the unit model of the civil engineering plant.

[0013] S70: Test the stability of the fixed civil engineering plant, check its quality and safety performance, and complete the construction of the civil engineering plant.

[0014] The technical advantages of the modular civil engineering plant construction method provided by this invention are as follows: Construction workers construct a three-dimensional model based on the design drawings of the civil engineering plant, and then optimize the structure on the three-dimensional model; the optimized three-dimensional model is divided into units to obtain unit models of the civil engineering plant; the unit models are prefabricated; a foundation is laid at the construction location of the civil engineering plant, and connecting components are installed on top of the foundation; the prefabricated unit models are transported to the construction site and assembled with the foundation using the connecting components; after assembly, the structure of the civil engineering plant is connected and fixed; the stability of the fixed civil engineering plant is tested to check its quality and safety performance, thus completing the construction of the civil engineering plant; this method solves the problem that most existing civil engineering plant constructions adopt integrated construction, resulting in long construction cycles, complex construction processes, and a waste of manpower and resources.

[0015] Based on the above technical solution, the modular civil engineering plant construction method of the present invention can be further improved as follows:

[0016] The specific steps for prefabricating the civil engineering plant unit model include:

[0017] The first step is to enlarge the width of the civil engineering factory unit model by 1.2 times and then 3D print it at a 1:1 scale.

[0018] The second step is to place the 3D-printed civil engineering factory model into a mold and pour molten resin material into it.

[0019] The third step is to completely submerge the civil engineering factory model with the melted resin material and then eliminate air bubbles by vibration.

[0020] Fourth step: After the resin material inside the mold has completely dried, cut the civil engineering factory model with a blade.

[0021] Fifth step: fix two steel bars horizontally and two vertically inside the mold; after fixing the mold together with transparent tape according to the structure of fixing the civil engineering factory model, pour concrete inside.

[0022] Step 6: After eliminating air bubbles by vibration, place the mold for pouring concrete in a dark place to dry.

[0023] Step 7: After drying for 3-4 days, remove the concrete and compact it along the width of the civil engineering plant unit model using a plate vibrator.

[0024] The eighth step involves trimming the compacted concrete and then placing it in a dry place to dry further, while also curing the surface of the concrete to construct the civil engineering plant unit model.

[0025] Furthermore, the specific steps for compaction along the width direction of the civil engineering plant unit model using a plate vibrator include:

[0026] The first step is to fix the plate vibrator at the top of the concrete, ensuring that the contact surface between the plate vibrator and the concrete is flat.

[0027] The second step is to adjust the vibration frequency, vibration force, and vibration time of the plate vibrator.

[0028] The third step is to start the plate vibrator and move it along the width of the civil engineering plant unit model to ensure that the plate vibrator evenly covers the entire width and maintains an appropriate vibration amplitude and speed.

[0029] Fourth, under the action of the plate vibrator, the concrete will gradually compact and expel air through the transmission of vibration force and vibration effect.

[0030] Fifth, repeatedly move the vibrator to cover the entire width until it reaches 5 / 6 of the concrete width.

[0031] The specific steps by which the construction workers divide the optimized 3D model of the civil engineering plant into unit models include:

[0032] The first step is to scan the 3D model of the optimized civil engineering plant structure to generate a point cloud map;

[0033] The second step is to voxelize the initial point cloud of the point cloud map to obtain multiple voxel cubes.

[0034] The third step is to select any of the voxel cubes as the center cube, calculate the fitting plane normal vector in each adjacent cube of the center cube, and calculate the angle between each fitting plane normal vector and the center fitting plane normal vector of the center cube. When the angle is less than a set angle threshold, it is determined that the center cube and the adjacent cube can be fitted to form a cube fitting plane, and the preliminary point cloud of the cube fitting plane is determined.

[0035] The third step is to project the three-dimensional data of the cube fitting plane onto the cube fitting plane to form two-dimensional data, divide the two-dimensional data into grids, and compare the number of points in each grid with a set point count threshold. Grids with a point count greater than the point count threshold are numbered as new data points, and the new data points are numbered and classified based on a clustering algorithm to obtain the fine segmentation plane of the cube fitting plane.

[0036] Fifth, repeat the above process until the initial point cloud is traversed to obtain all the finely segmented surfaces, and optimize the over-segmented surfaces in the finely segmented surfaces;

[0037] The sixth step is to divide the optimized 3D model of the civil engineering plant into units.

[0040] The second step is to prepare four steel bars, two of which are 1cm longer than the horizontal length of the mold, and the other two are 1cm longer than the width of the mold.

[0041] The third step is to fix the reinforcing bars along the transverse and width directions of the mold, respectively;

[0042] The fourth step is to wrap and fix the mold with tape to ensure its sealing and integrity;

[0043] The fifth step is to gradually and slowly add concrete into the fixed mold while continuously vibrating it to eliminate air bubbles.

[0044] The specific steps for the construction workers to construct a three-dimensional model based on the design drawings of the civil engineering plant and to perform structural optimization on the three-dimensional model include:

[0045] The first step involves the construction personnel classifying the interior of the foundation walls according to the civil engineering plant design drawings and the actual foundation conditions, using a hierarchical classification method. They then propose a coding rule based on information organization to code each part of the civil engineering plant.

[0046] The second step is for the construction personnel to standardize the parameters of each part of the civil engineering plant, create a shared parameter file, and use it in different families and projects.

[0047] The third step involves the construction personnel using the Revit software platform to build three-dimensional models of each part of the civil engineering plant based on the above classification results and the scheme on the construction design drawings. They then classify and summarize the three-dimensional models to establish the civil engineering plant family library.

[0048] The fourth step involves the construction personnel calling upon various components from the civil engineering plant family library based on the actual situation of the civil engineering plant. Through external data file drivers, they modify the parameters of the civil engineering plant components and generate corresponding instances.

[0049] The fifth step involves the construction workers assembling the components to create a complete three-dimensional model of the civil engineering plant.

[0050] The sixth step involves the construction personnel optimizing the structure of the civil engineering plant based on the 3D model displayed therein to ensure its stability and safety.

[0051] Furthermore, each of the civil engineering plant unit models is provided with a hook-and-loop connector on its side, which is used to connect and fix the civil engineering plant unit models to each other and to the foundation.

[0052] Furthermore, the hook-and-loop connector comprises two parts: a protruding part and a recessed part. The protruding part and the recessed part are respectively disposed at one end between the civil engineering plant unit models and at one end between the civil engineering plant unit models and the foundation, and the recessed part is disposed at the other end. The protruding part and the recessed part cooperate with each other to fix the civil engineering plant unit models between each other and between the civil engineering plant unit models and the foundation.

[0053] Furthermore, the protruding portion includes a connecting platform, a rotating shaft, a rotating plate, and a compression spring. The connecting platform has a square structure and is fixed on the civil engineering plant unit model and the foundation. There are two rotating shafts, which are respectively arranged on the left and right sides of the connecting platform. The rotating plate is rotatably connected to the connecting platform through the rotating shafts. The compression spring is arranged between the connecting platform and the rotating plate, with one end fixedly connected to the connecting platform and the other end fixedly connected to the corresponding position of the rotating plate.

[0054] The recessed portion has a square hole structure, and the bottom of the square hole structure is connected to the outside.

[0055] Furthermore, a groove is provided on the inner bottom of the square hole structure, which is used to fix the rotating plate; a protrusion is provided on the groove, which is used to increase the friction between the rotating plate and the square hole structure.

[0056] Furthermore, the length of the rotating plate is half the bottom length of the square hole; the height of the square hole is less than the length of the rotating plate.

[0057] Furthermore, the compression spring is a rigid spring.

[0058] Compared with existing technologies, the modular civil engineering plant construction method provided by this invention has the following advantages: Construction workers construct a three-dimensional model based on the design drawings of the civil engineering plant, and then optimize the structure on the three-dimensional model; the optimized three-dimensional model is divided into units to obtain unit models; the unit models are prefabricated; a foundation is laid at the construction location of the civil engineering plant, and connecting components are installed on top of the foundation; the prefabricated unit models are transported to the construction site and assembled with the foundation using the connecting components; after assembly, the structure of the civil engineering plant is connected and fixed; the stability of the fixed civil engineering plant is tested to check its quality and safety performance, thus completing the construction of the civil engineering plant; this method solves the problem that most existing civil engineering plant construction methods adopt integrated construction, resulting in long construction cycles, complex construction processes, and a waste of manpower and resources.
