Description

Technical Field

[0001] This utility model relates to the field of substation construction technology, specifically to a substation foundation. Background Technology

[0002] The foundation of a substation serves as the basis for various electrical equipment. It is primarily a reinforced concrete structure, including structural columns and cast-in-place concrete ground beams connecting the various structural columns. For areas without large electrical equipment, such as the living quarters of the substation, the cable routing can be planned in advance, and cable trenches can be reserved to avoid intersections between cable trenches and ground beams. For reserved cable trenches, the ground beam height can be raised to avoid these intersections. However, for areas that support large electrical equipment, since civil engineering is usually carried out first, followed by the installation of electrical equipment, the reserved cable trenches often cannot meet the needs of cable laying. This can easily lead to conflicts between newly constructed cable trenches and ground beams, requiring the ground beams to be hollowed out or drilled through to create cable trenches. However, hollowing out or drilling through ground beams during construction is cumbersome and costly. Utility Model Content

[0003] The main purpose of this utility model is to provide a substation foundation to solve the problem of existing substation foundation beams conflicting with cable trenches, requiring the beams to be hollowed out or drilled through.

[0004] To achieve the above objectives, this utility model provides a booster station foundation, comprising:

[0005] The support assembly includes multiple sets of foundation piers, structural columns mounted on the foundation piers, and ground beams detachably connected to the structural columns; the foundation piers and structural columns are cast-in-place concrete structures; the ground beams are precast concrete structures.

[0006] The connecting assembly includes a connecting steel sleeve mounted on the structural column and connectors mounted at both ends of the ground beam; an adjusting element is provided between the connecting steel sleeve and the connector; the connector is connected to the connecting steel sleeve to connect the ground beam to the structural column; the adjusting element moves up or down under the action of external force, thereby adjusting the height of the ground beam relative to the structural column.

[0007] As a further improvement of this utility model, the connecting steel sleeve is integrally cast with the structural column and abuts against the foundation pier column. The connecting steel sleeve is provided with multiple sets of paired connecting steel plates at intervals. The connecting steel plates are provided with connecting holes. The connecting head is provided with a limiting steel plate. The limiting steel plate is provided with a limiting hole. The limiting hole is provided with a connecting stud.

[0008] As a further improvement of this utility model, anchor rods are provided at intervals on the inner wall of the connecting steel sleeve, and an abutting steel plate is provided at the bottom outer end of the connecting steel sleeve; the abutting steel plate is fixedly connected to the two pairs of connecting steel plates.

[0009] As a further improvement of this utility model, the connecting hole is an elongated slot; a positioning steel plate is provided between the limiting steel plates; the adjusting component includes a positioning sleeve provided on the abutting steel plate and an adjusting screw provided on the positioning steel plate; a positioning screw hole is provided on the positioning steel plate; the positioning sleeve and the positioning screw hole are coaxially arranged.

[0010] The beneficial effects of this utility model are reflected in:

[0011] The precast ground beam and structural column can be detachably connected by connecting steel sleeves and connectors. The precast ground beam can connect multiple sets of structural columns. During the installation of electrical equipment, if newly laid cables conflict with the ground beam, the height of the ground beam can be adjusted by changing the connection position of the connector and connecting steel sleeve, leaving space for cable laying. There is no need to hollow out the area under the ground beam or chisel through the ground beam, making construction more convenient and faster and saving construction costs.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In one embodiment, see Figure 1 The present invention relates to a substation foundation, comprising a support component and a connecting component.

[0020] The supporting components include multiple sets of foundation piers 1, structural columns 2 set on the foundation piers 1, and ground beams 3 detachably connected to the structural columns 2; the foundation piers 1 and structural columns 2 are cast-in-place concrete structures; the ground beams 3 are precast concrete structures; the connecting components include connecting steel sleeves 4 set on the structural columns 2 and connecting heads 5 set at both ends of the ground beams 3, with an adjusting element 6 between the connecting steel sleeves 4 and the connecting heads 5, and the connecting heads 5 are connected to the connecting steel sleeves 4 to connect the ground beams 3 and the structural columns 2; the adjusting element 6 moves up or down under the action of external force, thereby adjusting the height of the ground beams 3 relative to the structural columns 2.

[0021] Preferably, the foundation pier 1, structural column 2, and ground beam 3 are all reinforced concrete structures.

[0022] Further, see Figure 2 The connecting steel sleeve 4 is integrally cast with the structural column 2 and abuts against the foundation pier column 1. The connecting steel sleeve 4 is provided with multiple sets of two pairs of connecting steel plates 7 at intervals. The connecting steel plates 7 are provided with connecting holes 8. The connecting head 5 is provided with a limiting steel plate 9. The limiting steel plate 9 is provided with a limiting hole 10. The limiting hole 10 is provided with a connecting stud 11.

[0023] Preferably, the connecting steel sleeve 4 and the connector 5 are both hollow rectangular bodies with openings at both ends, and both are made of steel.

[0024] Preferably, two sets of limiting steel plates 9 are provided, and the two sets of limiting steel plates 9 are welded to the connector 5 at intervals.

[0025] Preferably, the connecting holes 8 are spaced apart on the connecting steel plate 7.

[0026] In the above configuration, the connecting steel sleeve 4 is integrally cast with the foundation pier 1 and the structural column 2 to ensure the stability of the connection between the three. Since the substation foundation is rectangular, the structural column 2 is located on the side, top corner and inside of the rectangular frame. The structural column 2 located on the side of the rectangular frame needs to be connected with the structural columns 2 facing the top corner on both sides, and also needs to be connected with the structural column 2 located inside the rectangular frame. At this time, the three sides of the connecting steel sleeve 4 connected to the structural column 2 on the side of the rectangular frame are provided with pairs of connecting steel plates 7; similarly, the two sides of the connecting steel sleeve 4 connected to the structural column 2 at the top corner of the rectangular frame are provided with pairs of connecting steel plates 7; the four sides of the connecting steel sleeve 4 connected to the structural column 2 located inside the rectangular frame are provided with pairs of connecting steel plates 7. The connecting steel plates 7 and the limiting steel plates 9 on the connector 5 are connected by connecting studs 11, thereby connecting the structural column 2 and the ground beam 3.

[0027] Further, see Figure 3 Anchor rods 12 are spaced apart on the inner wall of the connecting steel sleeve 4, and abutting steel plate 13 is provided at the bottom outer end of the connecting steel sleeve 4. The abutting steel plate 13 is fixedly connected to the two pairs of connecting steel plates 7.

[0028] Preferably, the anchor rods 12 are spaced apart on the four sets of inner walls of the connecting steel sleeve 4, and the anchor rods 12 are inserted into the steel bars inside the structural column 2.

[0029] Preferably, the abutting steel plate 13 is a rectangular plate with a through hole 14 in the center. The through hole 14 is opposite to the opening end of the connecting steel sleeve 4. The abutting steel plate 13 is welded to the connecting steel sleeve 4 and the two pairs of connecting steel plates 7.

[0030] In the above configuration, after the connecting steel sleeve 4 and the structural column 2 are cast together, the anchor rod 12 and the steel bars inside the structural column 2 are connected by concrete to increase the connection stability between the connecting steel sleeve 4 and the structural column 2, and the abutting steel plate 13 is located on the foundation pier column 1.

[0031] Further, see Figure 4 The connecting hole 8 is an elongated slot, and a positioning steel plate 15 is provided between the limiting steel plates 9; the adjusting component 6 includes a positioning sleeve 16 provided on the abutting steel plate 13 and an adjusting screw 17 provided on the positioning steel plate 15. The positioning steel plate 15 is provided with a positioning screw hole, and the positioning sleeve 16 and the positioning screw hole are coaxially arranged.

[0032] Preferably, the positioning sleeve 16 is a hollow cylinder with one end open, and the positioning sleeve 16 is welded to the abutting steel plate 13.

[0033] In the above setup, the limiting steel plate 9 is moved upward by moving the ground beam 3 upward, which changes the connection position between the limiting hole 10 and the connecting hole 8. The limiting plate and the connecting plate are stably connected by the connecting stud 11 passing through the connecting hole 8, the limiting hole 10 and the nut. Then, the adjusting screw 17 is rotated and enters the positioning sleeve 16 under the action of the thread. The adjusting thread abuts against the positioning sleeve 16, thereby providing support for the positioning steel plate 15, and thus providing support for the entire ground beam 3.

[0034] In this embodiment, the ground beam 3 is connected to the structural column 2 via a connecting sleeve and to the limiting steel plate 9 via a connecting steel plate 7, thereby adjusting the position of the ground beam 3. When there is a conflict between the cable and the ground beam 3 on the same horizontal plane, the position of the ground beam 3 is raised, and the height of the ground beam 3 is fixed by connecting the connecting stud 11 and the nut. Then, the adjusting screw 17 and the abutting steel plate 13 are used to abut against each other to provide stable support for the ground beam 3, so that a new cable trench can be opened without affecting the overall strength of the ground beam 3. Furthermore, the entire substation foundation mainly relies on the structural column 2 for bearing capacity, and adjusting the position of the ground beam 3 will not affect the bearing capacity of the substation foundation. After the ground beam 3 is adjusted and raised, backfill is placed under the ground beam 3 to support it.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
