DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with specific embodiments.

[0032] Example 1: As Figures 1-4 As shown in the figure, the combined raft structure integrating rotation and translation functions described in this embodiment of the invention includes a rotating raft 1, and a slide beam column 2 is provided on the side of the rotating raft 1.

[0033] The slide beam 3 is fixedly connected to the side of the slide beam column 2, and the column connecting beam 4 is fixedly connected to the side of the slide beam 3.

[0034] The slide beam column 2 is fixedly connected to the slide beam column foundation 5 on the side away from the slide beam 3;

[0035] The rotating raft 1 is equipped with a linear displacement slide, which is precisely calculated using BIM. At the same time, the displacement slide is fixedly connected to the surrounding reinforced concrete of the rotating raft 1.

[0036] The existing raft foundation technology has several drawbacks: low displacement accuracy (relying on manual measurement and experience-based adjustments, making it difficult to achieve millimeter-level precision control, especially when adjusting complex curves or rotation angles); low construction efficiency (the matching of track positioning, raft foundation pouring, and displacement track depends on on-site layout, and BIM technology is only used for preliminary modeling and not throughout the entire construction process, resulting in large errors in the connection between various processes and significant material waste (repeated reinforcement of rotating and translational raft foundations, with steel and concrete usage exceeding actual requirements by 26%).

[0037] In use, this invention incorporates an arc-shaped rotation system, with the rotational positions of the old and new buildings serving as the rotational edges and the intersection point as the rotation center. The rotating equipment's travel path is structured around a system with a maximum length of 58m, a maximum width of 51m, and a raft slab thickness of 600mm. Figure 1 As shown;

[0038] The linear displacement system is located inside the rotating raft 1, with a maximum length of 32m and a reinforced concrete slide beam 3 with a cross-section of 2000mm × 600mm, connected to the surrounding reinforced concrete of the rotating raft 1. Figure 2 As shown;

[0039] After placing the displacement slide rail inside the rotating raft 1, BIM is used for precise calculations and construction simulation to optimize the excess reinforced concrete inside the raft slab, ensuring the accuracy of the displacement.

[0040] The sliding beams of the rotating and translational sections were cast in one go. By optimizing the process through BIM progress simulation, the construction period was reduced from 45 days to 30 days, and material waste was reduced by 26%.

[0041] In summary, this invention achieves an integrated slide system: It designs a gradual transition node between the arc-shaped rotating slide and the straight-line translation slide, avoiding separate construction and achieving seamless connection between the two displacement modes; BIM precise control: Utilizing BIM technology for unified modeling, it accurately plans the rotation center (coordinate origin) and translation baseline, ensuring that the error throughout the composite displacement is ≤±3mm; Composite stress optimization: Through finite element analysis of the superimposed loads of rotation and translation, it specifically adjusts the raft reinforcement and the section of slide beam 3, reducing structural safety risks and improving construction efficiency: Slide beam 3 is cast in one piece, reducing formwork disassembly and node reconstruction processes, shortening the construction period, and reducing material waste.

[0042] Example 2: Figures 5-8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the surface of the rotating raft plate 1 is provided with a side groove 6, and the inside of the side groove 6 is provided with an expanding rubber 7. The surface of the rotating raft plate 1 is provided with a rectangular groove 1 8 and a rectangular groove 2 9, which are located on the upper and lower sides of the side groove 6, respectively. A telescopic box 10 is movably inserted inside the rectangular groove 1 8, and a telescopic box 2 11 is movably inserted inside the rectangular groove 2 9. A compression plate 12 is movably inserted inside both the telescopic box 10 and the telescopic box 2 11. Both the telescopic box 10 and the telescopic box 2 11 are connected to the compression plate 12 by a spring 13. The sides of both the telescopic box 10 and the telescopic box 2 11 are fixedly connected to the telescopic end of the electric push rod 14. A drain pipe 15 is fixedly connected to the side of the telescopic box 2 11 away from the electric push rod 14. One end of the drain pipe 15 penetrates the soil and extends to the outside of the soil to drain water from the soil. The drain pipe 15 communicates with the telescopic box 2 11. A controller is provided on the rotating raft plate 1.

[0043] When a gap is formed between the outer side of the rotating raft 1 and the foundation, water will more easily flow into this gap and come into contact with the foundation. If the foundation is soaked in water for a long time, it will reduce the stability of the rotating raft 1 on it.

[0044] When the present invention is in use, when a gap is generated between the foundation and the outer side of the rotating raft 1, and water flows into this gap along the rotating raft 1, the water comes into contact with the expanding rubber 7, causing the expanding rubber 7 to absorb water and expand, thereby sealing and repairing the gap between the rotating raft 1 and the foundation, making it difficult for water to come into contact with the foundation.

[0045] Afterwards, the telescopic box one 10 and the telescopic box two 11 are pushed out from the rectangular groove one 8 and the rectangular groove two 9 respectively by the electric push rod 14, after being pushed out, the limiting effect of the rectangular groove one 8 and the rectangular groove two 9 on the extrusion plate 12 is released, afterwards, under the elastic force of the spring 13, the extrusion plate 12 is pushed to extrude and move on the expanded rubber 7, so that the expanded rubber 7 is treated by water extrusion, and then the expanded rubber 7 will restore a certain water absorption capacity, so that the expanded rubber 7 can continuously absorb water;

[0046] When the expanded rubber 7 is treated by water extrusion, the extruded water will enter the telescopic box two 11, and then be discharged to the outside of the foundation through the drain pipe 15.

[0047] As described above, in use, the gap between the rotating raft 1 and the foundation is sealed by the water absorption and expansion of the expanded rubber 7, so that the foundation is not easily soaked by water, after the expanded rubber 7 absorbs water, it is extruded by a pair of extrusion plates 12 to restore a certain water absorption capacity, and finally the water is discharged through the drain pipe 15, so that the foundation is not easily soaked by water, and the stability of the rotating raft 1 and the building on the foundation can be improved.

[0048] As shown in Figure 6 , the inner side walls of the rectangular groove one 8 and the rectangular groove two 9 are fixedly connected with the other end of the corresponding electric push rod 14.

[0049] As shown in Figure 5 , in the initial state, the side surfaces of the expanded rubber 7, the telescopic box one 10 and the telescopic box two 11 are flush with the side surface of the rotating raft 1.

[0050] As shown in Figure 7 , the side surface of the extrusion plate 12 is provided with a chamfer, and in the initial state, the spring 13 is in a contracted state.

[0051] As shown in Figure 8 , the drain pipe 15 is fixedly connected with an alarm 16, and the alarm 16 is electrically connected with a controller through wires, when the drain pipe 15 discharges water and triggers the expanded rubber 7 to seal the gap, the alarm 16 will be started, reminding personnel that a gap is generated between the foundation and the rotating raft 1.

[0052] As shown in Figure 9 , the outside of the alarm 16 is sleeved with a sleeve cover 17, the sleeve cover 17 is made of transparent material, and the bottom of the sleeve cover 17 abuts against the top of the drain pipe 15, so that the alarm 16 can be protected by the sleeve cover 17.

[0053] As shown in Figures 8-9As shown, the inner wall of the sleeve cover 17 is coated with a magnetic coating 18, and the outer part of the alarm 16 is coated with a magnetic coating 19 which is magnetically connected with the magnetic coating 18. After the magnetic coating 18 and the magnetic coating 19 are adsorbed together, the stability of the sleeve cover 17 on the outer part of the alarm 16 can be improved.
