[0038] See also Figure 1 The laterite nickel ore smelting equipment platform construction method provided by the present invention comprises the following steps:

[0039] S1, build BIM model.

[0040] It is understandable that the above steps may further include:

[0041] S101, extract IFC files through construction drawings.

[0042] It is known that 3D scanning or reverse modeling technology can be used to extract IFC files of construction drawings.

[0043] S102, constructing an initial model through IFC files;

[0044] S103: Modify the initial model and assign a corresponding first identifier to each virtual component to form a BIM model.

[0045] It can be known that optimizing the initial model includes deleting irrelevant details, merging similar components, etc. to achieve lightweight model, and then assigning a corresponding first identifier to each component of the BIM model. The unique identifier can be a QR code, and the QR code assigned to each virtual component is unique.

[0046] S2, build the formwork according to the BIM model, where PP hollow formwork is used for large-section parts, and wooden formwork is used for splicing at the corners.

[0047] It is understandable that the above steps may further include:

[0048] S201, obtaining steel structures, wherein each steel structure is marked with a corresponding second identifier, and each second identifier corresponds to a first identifier.

[0049] It's known that the second identifier can also be a QR code. Each virtual component corresponds to a steel structure, and the QR code on the steel structure can be pasted or printed on its surface. At every stage of the component's flow, such as factory delivery, transportation, unloading, and installation, scanning the QR code on the steel structure can record its location and status in real time, enabling full tracking.

[0050] S202, selecting a steel structure according to a second identifier corresponding to the first identifier;

[0051] S203, construct the steel structure according to the position of the corresponding virtual components to form a template, wherein the large-section part adopts PP hollow template, and the corner parts adopt wooden template for splicing.

[0052] It can be known that the corresponding first identifier can be found according to the second identifier, and the corresponding steel structure can be assembled according to the position information of the virtual component corresponding to the first identifier. PP hollow formwork is used for large-section parts, and wooden formwork is used for the corner parts, which can improve the strength of the formwork and the concrete molding effect. The large-section part can be the main part of the base pier of the formwork, the formwork strength is moderate, and the concrete molding effect is good; the corner parts can be the corner parts of the base pier of the formwork, and wooden formwork is used. The formwork strength is high and can ensure the molding quality of the corner parts. The segmented position of the steel bar connection during the formwork construction process needs to be optimized, and the high-strength straight threaded sleeve connection technology is used to form a scientific and reasonable structural structure to ensure the overall structural strength. The steel bar connection nodes can be reasonably arranged according to the structural characteristics of the equipment platform foundation, and the number of connections can be reduced as much as possible to improve continuity. For the ends of the steel bars that need to be connected, high-strength straight threaded sleeves are used for mechanical anchoring, and the anchoring length is not less than 40 times the diameter of the steel bar to ensure a reliable connection. Please refer to Figure 3 When building the template, the template may include a basic base plate 1, which can enclose a space range. The vertical poles 5 are fixed within the space range, and a certain amount of space is reserved between adjacent vertical poles 5 according to actual needs. A cantilever plate 9 is also fixed on the vertical poles 5, and the vertical poles 5 can be connected by a cross bar 6. A sweeping rod 2 can also be set at the bottom of the vertical pole 5, and a scissors brace 3 can be connected between the cross bar 6 and the vertical pole 5, thereby forming a support frame, and some monitoring points 4 can also be set on the template on the support frame.

[0053] S204, determine the construction status of the steel structure.

[0054] S205: Mark each virtual component in the BIM model according to the construction situation.

[0055] What we know is that in the BIM model, each virtual component is assigned a unique QR code, and the BIM model can also be connected to the QR code process management system. According to the real-time construction status of the steel component, the color of the virtual component of the corresponding component in the BIM model is changed accordingly, or other marking forms are used, so as to intuitively display the construction progress of the entire project.

[0056] S3, using the inclined layered casting method to cast the formwork to form the equipment platform foundation 7.

[0057] It is understandable that the above steps may further include:

[0058] See also Figure 2 and Figure 4, optimize the concrete mix ratio, control the pouring height, and adopt the inclined layered pouring method to reduce the internal hydration heat generation and avoid temperature cracks. The inclined layered pouring method needs to control the height of a single pouring to no more than 6 meters. The inclined layered pouring method can be to first pour the foundation of the equipment platform foundation, then pour the first concrete column, the pouring height can be 4 meters, and then the first concrete column pouring, the pouring height can also be 4 meters, followed by the third concrete column pouring, the pouring height is 2.8 meters. After the concrete column is poured in three sections, the top plate at the top of the concrete column is poured. The first top plate pouring is first carried out, the pouring height can be 1 meter, and then the second top plate pouring is carried out, the pouring height can be 1.9 meters. The equipment platform foundations can also be connected by a platform connecting plate 8. The above pouring method can reduce the accumulation of hydration heat and avoid the generation of temperature cracks. During the pouring interval, the construction surface needs to be roughened and coated with cement mortar to ensure the quality of the bonding surface during subsequent pouring. Regarding the raw materials used for pouring, the amount of cement, sand, gravel, admixtures and other raw materials in the concrete can be adjusted according to the on-site raw material conditions to optimize the mix ratio.

[0059] S4, installing the combined retainer on the equipment platform foundation 7.

[0060] It can be seen that the relative positioning of the electrodes in the combination gripper is optimized, reducing the electrode spacing and saving installation space. The electrode installation position can be optimized based on the equipment layout, keeping the spacing between electrodes within a range of 300-500 mm to save installation space. The combination gripper can adopt a modular design to adapt to different shapes, materials, and operating requirements. Specifically, the combination gripper can be broken down into functional modules, each designed independently, and assembled together using standardized interfaces to accommodate different shapes, materials, and operating requirements. By adjusting the installation process and optimizing the interleaving between various steps, the combination gripper can be installed quickly, efficiently, and safely, improving installation accuracy and reducing subsequent calibration time. The gripper installation process can be optimized, with each step arranged in a staggered manner to avoid construction space conflicts. Optimizing the lifting plan can also ensure the gripper's installation position accuracy, thereby reducing subsequent calibration and commissioning time.

[0061] From the above description, it can be seen that the laterite nickel ore smelting equipment platform construction method provided by the present invention, by adopting PP hollow formwork and wooden formwork construction technology, as well as the inclined layered casting method, can effectively solve the technical problem of concrete temperature cracks in the equipment platform foundation, thereby improving construction quality, safety and economy.
