[0026] The reinforcing assembly is used for reinforcing the whole of protective building 5, to improve the structural safety of protective building 5 during translation.

[0027] After translation, a pair of sandwich wall beam 1 can be retained as the foundation of protective building 5, to improve the integrity, stability and seismic capacity of the foundation of protective building 5, and only the part of wall lifting beam 2 located outside the wall of protective building 5 needs to be removed, greatly reducing the amount of demolition work.

[0028] Please refer to the accompanying drawings Figure 1 And the accompanying drawings Figure 2 A plurality of tie beams 4 are arranged at intervals in protective building 5, and each tie beam 4 is connected vertically between two oppositely arranged surfaces of sandwich wall beam 1 located on the inner side of protective building 5.

[0029] The tie beam 4 can be integrally cast with the sandwich wall beam 1, to further improve the structural strength and carrying capacity of the whole jacking system during the translation of protective building 5.

[0030] Meanwhile, the tie beam 4 is retained synchronously with the sandwich wall beam 1, and together serves as the foundation of protective building 5, and can serve as the support of the first-floor structural floor slab 501 of protective building 5, to further improve the integrity, stability and seismic capacity of the foundation of protective building 5.

[0031] Please refer to the accompanying drawings Figure 1Each of the reinforcing assemblies comprises a scissors brace 601, a horizontal brace 602, an inner reinforcing rib 603, an outer reinforcing rib 604 and a tie 605; the inner reinforcing rib 603 is vertically attached to the inner wall of the wall surface of the protected building 5, the outer reinforcing rib 604 is vertically attached to the outer wall of the wall surface of the protected building 5, and the tie 605 penetrates the wall surface of the protected building 5 and is fixedly connected with the inner reinforcing rib 603 and the outer reinforcing rib 604; the scissors brace 601 and the horizontal brace 602 are arranged between the two oppositely arranged wall surfaces of the protected building 5 and are fixedly connected between the two oppositely arranged inner reinforcing ribs 603 by means of angle codes or other fixing members.

[0032] Preferably, the reinforcing assemblies are made of steel structures, and the number and arrangement spacing of the reinforcing assemblies can be flexibly adjusted to form a roof support inside the protected building 5 to prevent the protected building 5 from deforming during the translation process. The reinforcing assemblies can be staggered with the wall-raising beams 2, or the bottom of the reinforcing assemblies can be fixed to the wall-raising beams 2 according to the construction requirements.

[0033] Through the arrangement of the scissors brace 601 and the horizontal brace 602, vertical and horizontal loads can be simultaneously borne, and through the arrangement of the inner reinforcing rib 603 and the outer reinforcing rib 604, the stress of the wall surface can be uniformly and stably borne, and the load transmission is facilitated.

[0034] Please refer to the accompanying drawings Figure 3 The first-floor structural floor 501 of the protected building 5 is constructed on the wall-clamping beams 1 and the connecting beams 4 located inside the protected building 5, and the mechanical and electrical pipelines 502 of the protected building 5 are arranged in the space enclosed by the first-floor structural floor 501, the basement roof 503 and the wall-clamping beams 1.

[0035] The wall-clamping beams 1 and the connecting beams 4 are used to construct the first-floor structural floor 501 of the protected building 5. Since the wall-clamping beams 1 and the connecting beams 4 have a certain height, a space is formed below the first-floor structural floor 501, forming a sandwich cavity, which can be used to arrange the mechanical and electrical pipelines 502 and other concealed works.

[0036] Please refer to the accompanying drawings Figure 3 The first-floor structural floor 501 and the basement roof 503 are provided with the ground ridge walls 504, a plurality of ground ridge walls 504 are arranged between the two oppositely arranged wall-clamping beams 1 located inside the protected building 5, and the ground ridge walls 504 are perpendicularly connected with the connecting beams 4 and are arranged staggered with the mechanical and electrical pipelines 502.

When backfilling the soil 506, the external wall beam 1 of the protected building 5 should be covered to prevent it from being exposed and affecting the aesthetics. If the backfill height of the soil 506 is insufficient to cover the wall beam 1, the wall beam 1 of the protected building 5 can be wrapped with decorative panels such as stone curtain walls to prevent it from being exposed.

[0043] Please see the appendix Figure 1 To be continued Figure 4 The construction method of this utility model is as follows:

[0044] Construct wall-clamping beams 1 on the inner and outer walls of the protected building 5 respectively. A pair of wall-clamping beams 1 form a closed loop structure along the bottom circumference of the protected building 5, and use the friction between the wall-clamping beams 1 and the wall surface to bear part of the load of the protected building 5.

[0045] Drill holes at the bottom of the wall of the protected building 5 and construct a lifting beam 2. The lifting beam 2 vertically penetrates the wall of the protected building 5 and extends to the inner and outer sides of a pair of clamping beams 1. The bottom surface of the lifting beam 2 is attached to the top surface of the pair of clamping beams 1, connecting the lifting beam 2 and the pair of clamping beams 1 into a whole to jointly bear the load.

[0046] A connecting beam 4 is constructed between the two opposing surfaces of the wall beam 1 on the inner side of the protected building 5 to improve the integrity, structural strength and load-bearing capacity of the wall beam 1.

[0047] The wall beam 1, the lifting beam 2, and the connecting beam 4 can be made of reinforced concrete and cast in one piece, with high integrity and structural strength, and can bear the load of the protected building 5 as a whole.

[0048] Jacks 3 are installed between the two ends of the lifting beam 2 and the translational surfaces such as the basement roof slab 503 of the protected building 5. The lifting beam 2 and the two jacks 3 are set up in groups, and the number of groups can be adjusted according to the load and process requirements.

[0049] Internal reinforcing ribs 603 are installed on the inner wall of the protected building 5, and external reinforcing ribs 604 are installed on the outer wall. Both internal and external reinforcing ribs 603 and 604 can be made of channel steel. Tie bolts 605 can be used as tie rods. The tie bolts penetrate the wall of the protected building 5 and connect and fix the internal and external reinforcing ribs 603 and 604.

[0051] A scissor brace 601 is installed between two opposing inner reinforcing ribs 603. The top two ends of the scissor brace 601 share angle brackets with the horizontal brace 602 and are fixed to the two opposing inner reinforcing ribs 603. The bottom two ends of the scissor brace 601 are fixed to the two opposing inner reinforcing ribs 603 by bolts using angle brackets. The scissor brace 602 can be formed by three I-beams intersecting and connected by connectors to form an X-shaped structure.

[0052] The protective building 5 was moved as a whole using a lifting system formed by the wall beam 1, the lifting beam 2, the jack 3, and the connecting beam 4. The moving process adopted the existing technology of building whole-building moving process, which will not be described in detail here.

[0053] After the relocation is completed, remove the lifting beam 2 and jack 3, and retain a pair of clamping beams 1 and connecting beam 4 to reduce the amount of demolition work. The retention of the pair of clamping beams 1 will significantly enhance the stability, integrity, and seismic resistance of the foundation of the protected building 5. The lifting beam 2 can be cut and removed using conventional techniques such as water drilling and wire sawing, which will not be described in detail here.

[0054] Because of the retention of a pair of wall beams 1, the elevation of the first floor of the protected building 5 is raised. After the translation is completed, the first floor slab 501 is directly constructed on the wall beams 1 and the connecting beams 4 inside the protected building 5. If the span of the first floor slab 501 is large, a ground joist wall 504 is constructed between the opposite sides of the wall beams 1. The ground joist wall 504 intersects the connecting beams 4 perpendicularly, and the wall beams 1, the connecting beams 4, and the ground joist wall 504 are used as supports for the first floor slab 501.

[0055] A cavity is formed between the basement roof slab 503, the wall beam 1 within the protected building 5, and the first-floor structural slab 501. This cavity provides a certain degree of moisture isolation, improving the living experience of the protected building 5. Simultaneously, concealed works such as mechanical and electrical pipelines 502, typically located within the ceiling, can be moved to this cavity, increasing the first-floor ceiling height and ensuring the first-floor height. During construction, holes can be drilled in the connecting beam 4 using a water drill for the installation of mechanical and electrical pipelines 502. The layout of the mechanical and electrical pipelines 502 can be constructed according to the detailed mechanical and electrical design requirements, which will not be elaborated here.
