Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a prefabricated high-resistance equipment foundation. Background Technology

[0002] High-voltage reactors are an important type of electrical equipment in substations. They are characterized by their large weight and significant vibration during operation, thus requiring high-quality foundations. The concrete foundation of a high-voltage reactor is the core structure supporting the equipment and transferring loads to the ground. Its form must be determined comprehensively based on the reactor type, installation method, geological conditions, and engineering economics.

[0003] In existing technologies, raft foundations are usually cast in place. However, the method of casting in place requires the production or transportation of a large amount of concrete on site. When the construction space is small, the operation is difficult. In addition, since the entire foundation is cast in place, a lot of time is required to wait for the concrete to solidify.

[0004] The existing high-resistance equipment foundations are made by on-site casting, which results in a large amount of on-site work, a large space occupation, and a long construction period. Utility Model Content

[0005] This utility model embodiment provides a prefabricated high-resistance equipment foundation, which can solve the problems of large on-site workload, large space occupation, and long construction period in the prior art. The technical solution is as follows: A prefabricated high-resistance equipment foundation for supporting high-resistance equipment includes: a first prefabricated component and a second prefabricated component. The first precast component and the second precast component are strip-shaped structures. Multiple first precast components are provided, and multiple first precast components are arranged side by side. At least two second precast components are provided, and the two second precast components are arranged at intervals. The second precast components are horizontally arranged on the first precast components and perpendicular to the first precast components. A pre-embedded steel plate is provided on the top of the second precast component, and the pre-embedded steel plate is used for welding the high-resistance equipment.

[0006] Optionally, the first precast component is a T-shaped structure, and a casting groove is provided on the edge of the wing plate of the first precast component, with the casting grooves of two adjacent first precast components connected.

[0008] Optionally, the reinforcing member further includes a sealing block, which is fixed in the middle of the steel mesh, and the bottom of the sealing block is disposed in the casting groove of two adjacent first precast members.

[0009] Optionally, multiple casting grooves are provided, and the multiple casting grooves are arranged at intervals along the length direction of the first precast component.

[0010] Optionally, the sidewall of the casting trough is provided with a connection hole, and multiple casting troughs are connected through the connection hole.

[0011] Optionally, the top of the first precast component is provided with a vertical reinforcing rib, and the bottom of the second precast component is provided with a casting hole, wherein the reinforcing rib is inserted into the casting hole.

[0012] Optionally, the second preform has a concave structure, and the top of the first preform has a limiting groove along the length direction of the second preform, and the bottom of the second preform cooperates with the limiting groove.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the overall structure provided in an embodiment of the present utility model; Figure 2 This is an exploded view of the overall structure provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the mating of the first preform and the second preform provided in this embodiment of the utility model; Figure 4 This is a schematic diagram of the structure of the first prefabricated component provided in this embodiment of the present invention; Figure 5 This is a schematic diagram of the second prefabricated component structure provided in this embodiment of the present invention; Figure 6 This is a schematic diagram of the reinforcing member structure provided in an embodiment of this utility model. A prefabricated high-resistance equipment foundation, used to support the high-resistance equipment 101, includes: a first prefabricated component 1 and a second prefabricated component 2. The first prefabricated component 1 and the second prefabricated component 2 are strip-shaped structures. Multiple first prefabricated components 1 are provided, arranged side-by-side. At least two second prefabricated components 2 are provided, arranged at intervals. The second prefabricated components 2 are horizontally positioned on the first prefabricated components 1 and perpendicular to them. A pre-embedded steel plate 3 is provided on the top of the second prefabricated component 2, and the pre-embedded steel plate 3 is used for welding the high-resistance equipment 101.

[0021] For example, in this embodiment of the present invention, multiple first precast components 1 can be fixed together by concrete pouring or by pre-reserved reinforcing bars and welding them together, thereby making the multiple first precast components 1 a whole. Second precast components 2 are placed on the first precast components 1 to provide bottom support for the high-resistance equipment 101; at least two second precast components 2 are sufficient to provide stable support for the high-resistance equipment 101. The second precast components 2 and the first precast components 1 can still be fixed together by pouring or welding reinforcing bars, thereby strengthening the connection strength between the second precast components 2 and the first precast components 1. The second precast component 2 is placed perpendicularly to the first precast component 1, forming a grid-like stress system. This reduces unidirectional weakness, improves the overall workability of the foundation, and allows vertical loads to be more fully distributed over a larger contact area at the intersections, resulting in lower local compressive stress peaks and improved ultimate bearing capacity. The interlocking of the second and first precast components 2 and 1 between the upper and lower layers enhances interface friction and geometric locking effects, effectively resisting horizontal forces and seismic shear forces and reducing the risk of inter-story slippage. This arrangement further improves the structural stability of the foundation. Compared to traditional on-site casting methods, this embodiment uses precast component assembly, requiring only local casting or welding at the connection points to increase the connection strength between components. This achieves the goal of providing a stable foundation for the high-resistance equipment 101, reducing the space and time required for on-site construction and improving construction efficiency.

[0022] This utility model provides a prefabricated high-resistance equipment foundation, assembled from a first prefabricated component 1 and a second prefabricated component 2. This reduces the volume of the smallest unit, facilitating the entry of various components into the construction site. The second prefabricated component 2 is perpendicular to the first prefabricated component 1, effectively resisting horizontal forces and seismic shear forces, reducing the risk of inter-story slippage. After the high-resistance equipment 101 is welded to the embedded steel plate 3, it can be stably fixed to this foundation. Furthermore, because prefabricated concrete components are used, there is no need to wait for the concrete to solidify on-site, thereby reducing the on-site construction period and the workload of workers. This effectively solves the problems of large on-site workload, large space occupation, and long construction period in existing technologies.

[0023] Optionally, the first precast component 1 has a T-shaped structure, and a casting groove 11 is provided on the edge of the wing plate of the first precast component 1, and the casting grooves 11 of two adjacent first precast components 1 are connected.

[0024] Exemplary, in embodiments of this utility model, such as Figure 4As shown, the flange of the first precast component 1 is attached to the ground, with the web facing upwards. The web, as the main vertical load-bearing component, is retained, eliminating the need for excess concrete. This reduces the manufacturing materials required for the first precast component 1, lowers manufacturing and transportation costs, and improves economic efficiency. After two adjacent first precast components are placed side by side, concrete is poured into the casting groove 11 to fix the adjacent first precast components 1, thereby improving the structural strength of the foundation.

[0025] Optionally, a reinforcing member 4 is provided in the casting trough 11. The reinforcing member 4 includes a steel mesh 41, which is vertically erected in the casting trough 11 of two adjacent first precast components 1.

[0026] Exemplary, in embodiments of this utility model, such as Figure 2 As shown, by setting the reinforcing member 4 in the pouring groove 11 and then pouring into the pouring groove 11, the steel mesh 41 can be mixed and fixed with the concrete, thereby enhancing the connection strength between two adjacent first precast components 1, and thus further improving the structural strength of the foundation. The use of the steel mesh 41 structure provides sufficient structural strength for pouring while also reducing the amount of steel used, thus lowering the manufacturing cost of the foundation.

[0027] Optionally, the reinforcing member 4 also includes a sealing block 42, which is fixed in the middle of the steel mesh 41, and the bottom of the sealing block 42 is disposed in the casting groove 11 of two adjacent first precast members 1.

[0028] Exemplary, in embodiments of this utility model, such as Figure 2 and Figure 6 As shown, the thickness of the reinforcing mesh 41 is usually less than the thickness of the pouring trough 11. If the reinforcing mesh 41 is placed directly into the pouring trough 11, the reinforcing mesh 41 is prone to tilting. The thickness of the sealing block 42 is similar to the width of the pouring trough 11, which can provide bottom support for the reinforcing mesh 41. In addition, the sealing block 42 can fill the gap at the junction of the two pouring troughs 11, preventing concrete from falling into the gap and causing waste during pouring.

[0029] Optionally, multiple casting troughs 11 are provided, and the multiple casting troughs 11 are arranged at intervals along the length direction of the first precast component 1.

[0030] Exemplary, in embodiments of this utility model, such as Figure 4 As shown, by setting multiple casting grooves 11, there are multiple connection points between two adjacent first precast components 1, which can more stably fix multiple first precast components 1 together, thereby further improving the structural strength of the foundation.

[0031] Optionally, a connection hole 12 is provided on the side wall of the casting trough 11, and multiple casting troughs 11 are connected through the connection hole 12.

[0032] Exemplary, in embodiments of this utility model, such as Figure 4 As shown, by opening the connection hole 12, when pouring one of the pouring troughs 11, the concrete can flow into the other pouring troughs 11 through the connection hole 12, thereby reducing the amount of work for workers to pour on site and improving the ease of operation of this foundation.

[0033] Optionally, the top of the first precast component 1 is provided with a vertical reinforcing rib 13, and the bottom of the second precast component 2 is provided with a casting hole 21, with the reinforcing rib 13 and the casting hole 21 being inserted into each other.

[0034] Exemplary, in embodiments of this utility model, such as Figure 3 As shown, there are two ways to install the reinforcing rib 13 and the first precast component 1. One method is to embed the reinforcing rib 13 into the first precast component 1 during casting. This method is more convenient, and the component is integrally formed after casting. The other method is to embed a threaded sleeve into the first precast component 1 during casting. The outer surface of the reinforcing rib 13 has matching threads. During assembly at the construction site, the reinforcing rib 13 is then threadedly connected to the embedded threaded sleeve in the first precast component 1. This method is more convenient for transporting the first precast component 1, preventing the reinforcing rib 13 from occupying space or breaking during transportation. Multiple reinforcing ribs 13 are provided. In this embodiment, two reinforcing ribs 13 are spaced apart along the width direction of the first precast component 1, forming one group. Multiple groups are spaced apart along the length direction of the first precast component 1. A matching number of casting holes 21 are provided at the bottom of the second precast component 2. By connecting the reinforcing rib 13 to the pouring hole 21, the relative movement between the second precast component 2 and the first precast component 1 along the length of the second precast component 2 can be restricted, thereby further improving the connection strength between the second precast component 2 and the first precast component 1. The pouring hole 21 can be opened from the top to the bottom of the second precast component 2 to form a through hole, which facilitates pouring from the top of the second precast component 2 into the pouring hole 21, further improving the connection strength between the second precast component 2 and the first precast component 1.

[0035] Optionally, the second preform 2 has a concave structure, and the top of the first preform 1 is provided with a limiting groove 14 along the length direction of the second preform 2, and the bottom of the second preform 2 is engaged with the limiting groove 14.

[0036] Exemplary, in embodiments of this utility model, such as Figure 3As shown, the second preform 2 has a concave structure. The bottom of the leg of the second preform 2 is matched with the limiting groove 14 to limit the relative movement between the second preform 2 and the first preform 1 along the length direction of the first preform 1, thereby further improving the connection strength between the second preform 2 and the first preform 1.

[0037] Optionally, the bottom of the second precast component 2 is provided with a shear column 22, and the top of the first precast component 1 is provided with a shear hole 15, and the shear column 22 is inserted into the shear hole 15.

[0038] Exemplary, in embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 5 As shown, by setting the anti-shear column 22 and the anti-shear hole 15 to be inserted and matched, the shear force generated between the second precast component 2 and the first precast component 1 during the use of the foundation can be reduced, thereby further improving the connection strength between the second precast component 2 and the first precast component 1.

[0039] Optionally, a vibration isolation device 5 is provided on the top of the second precast component 2. The vibration isolation device 5 includes a first connecting plate 51, a second connecting plate 52 and a vibration isolation layer 53. The vibration isolation layer 53 is disposed between the first connecting plate 51 and the second connecting plate 52. The first connecting plate 51 is welded to the embedded steel plate 3, and the second connecting plate 52 is welded to the bottom of the high-resistance equipment 101.

[0040] Exemplary, in embodiments of this utility model, such as Figure 2 As shown, the vibration isolation layer 53 is made of rubber or other vibration isolation materials that can provide a buffering effect. By setting the vibration isolation device 5, some of the vibration generated by the high-resistance equipment 101 can be absorbed by the vibration isolation layer 53, thereby reducing the damage of vibration to the foundation and improving the service life of the foundation.
