Abstract
Description
Technical Field
[0001] This utility model relates to a reactor foundation. Background Technology
[0002] Reactors are crucial electrical devices in power systems, primarily used for limiting short-circuit currents, voltage division, filtering, improving power factor, suppressing overvoltages, protecting equipment, smoothing DC output, preventing current surges, and enhancing grid stability. Through series or parallel connection, reactors ensure the safe and stable operation of the power system and improve energy utilization efficiency. In engineering projects, reactor foundations are typically made of concrete, rising approximately half a meter above ground level after pouring. Construction involves excavating the soil, laying a 100mm thick plain concrete pad, supporting formwork, pouring concrete, backfilling with soil, and then curing. Traditional concrete foundations not only waste load-bearing capacity but also require formwork, making the construction process less streamlined. Utility Model Content
[0003] The technical problem to be solved by this utility model is: Therefore, this utility model proposes a reactor foundation for use in general power generation projects, which can not only save costs but also simplify the construction process, and has very good economic benefits.
[0004] The specific technical solution of this utility model is as follows:
[0005] A reactor foundation includes an annular plain concrete foundation, which includes a bottom foundation and side foundations. The cross-section of the plain concrete foundation is U-shaped, and the side foundations form a ring. An intermediate backfill is provided in the middle part of the side foundation, and the height of the intermediate backfill is higher than the external ground level.
[0006] Several pre-embedded flat steel bars are installed above the side foundation. A steel bracket is installed above the pre-embedded flat steel bars, and an anchor bar is installed below the steel bracket. The anchor bar passes through the pre-embedded flat steel bars and is fixed to the plain concrete foundation. A top steel plate is installed on top of the steel bracket.
[0007] Six pre-embedded flat steel bars are installed above the side foundation, and the six pre-embedded flat steel bars are distributed in a circle.
[0008] A water outlet is provided on the side foundation. The water outlet is inclined and the drainage inlet of the water outlet is flush with the top surface of the middle backfill.
[0009] A grounding wire is installed on the inner side of the annular side foundation.
[0010] The beneficial effects of this utility model are as follows: The plain concrete foundation of this utility model does not require a subbase and has better insulation than the reinforced concrete foundation. Moreover, the overall U-shaped plain concrete foundation is cast in one piece, and the structure has integrity. The concrete at the bottom is not completely excavated, leaving a certain thickness to avoid punching damage after loading. Furthermore, the foundation bottom has a larger foundation area with the soil, resulting in lower pressure and more uniform stress distribution. Attached Figure Description

[0012] Figure 2 This is a top view of the present invention. Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] like Figure 1 As shown, a reactor foundation includes an annular plain concrete foundation 1. The plain concrete foundation 1 includes a bottom foundation 11 and side foundations 12. The cross-section of the plain concrete foundation 1 is U-shaped. The side foundations 12 form a ring around the perimeter. The middle of the side foundations 12 is hollowed out, which saves material costs. An intermediate backfill 2 is set in the middle part of the side foundations 12. The height of the intermediate backfill 2 is higher than the external ground level. After compaction, it will provide good support for the side columns.
[0016] Several pre-embedded flat steel bars 3 are installed above the side foundation 12. A steel bracket 4 is installed above the pre-embedded flat steel bars 3, and an anchor bar 5 is installed below the steel bracket 4. The anchor bar 5 passes through the pre-embedded flat steel bars 3 and is fixed to the plain concrete foundation 1. A top steel plate 6 is installed on the top of the steel bracket 4, and a reactor is connected through the top steel plate 6.
[0017] Furthermore, six pre-embedded flat steel bars 3 are provided above the side foundation 12, and the six pre-embedded flat steel bars 3 are distributed in a circle.
[0018] A water outlet 7 is provided on the side foundation 12. The water outlet 7 is inclined and the drainage inlet of the water outlet 7 is flush with the top surface of the middle backfill 2, which facilitates drainage and avoids water accumulation in the cavity of the U-shaped foundation from eroding the concrete.
[0019] Furthermore, a grounding wire 8 is provided on the inner side of the annular side base 12.
[0020] The plain concrete foundation 1 of this invention requires no subbase and has better insulation than reinforced concrete foundations. Furthermore, the integral U-shaped plain concrete foundation 1 is cast as a single piece, resulting in a structurally unified structure. The bottom concrete is not completely excavated, leaving a certain thickness to prevent punching damage under load. Additionally, the foundation bottom has a larger contact area with the soil, resulting in lower pressure and more even stress distribution.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
