Description

Technical Field

[0001] This utility model relates to the field of substation engineering technology, and in particular to a foundation for a power equipment support. Background Technology

[0002] The foundations of existing power equipment supports are mostly cast-in-place concrete, meaning they need to be poured on-site. This leads to difficulties in controlling construction quality and slow construction speed. A very small number of foundations are precast, or are large in size and weight, making transportation and on-site installation difficult; or require secondary grouting at foundation connections, but the curing time for secondary grouting is long, which doesn't meet the on-site installation time. The time from construction to curing completion for existing power equipment support foundations is generally more than 8 days. In cold regions where temperatures do not meet the construction requirements, additional winter construction plans are needed, causing significant inconvenience to construction.

[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0031] like Figure 1 As shown, an embodiment of this utility model provides a foundation for a power equipment support, comprising:

[0032] First reinforced concrete member 1;

[0033] A second reinforced concrete member 2 is disposed opposite to the first reinforced concrete member 1;

[0034] Multiple wedge-shaped connectors 3 connect the first reinforced concrete component 1 and the second reinforced concrete component 2;

[0035] The first reinforced concrete component 1 is partially buried below ground level, and the second reinforced concrete component 2 is completely buried below ground level.

[0036] In this embodiment, the first reinforced concrete member 1 is as follows: Figure 1 As shown, the second reinforced concrete member 2 is as follows Figure 2 As shown. Figure 3 As shown, the first reinforced concrete member 1 and the second reinforced concrete member 2 are aligned during construction, with the bottom surface of the first reinforced concrete member 1 in complete contact with the top surface of the second reinforced concrete member 2, and they are equal in size and shape. The first reinforced concrete member 1 and the second reinforced concrete member 2 are connected by a wedge-shaped connector 3, as shown in the diagram. Figure 4As shown. Since the first reinforced concrete component 1 and the second reinforced concrete component 2 are two completely independent components, and the length, width, and height of both components do not exceed 1.2 meters, and their respective weights are controlled within 1.5 tons, they are not subject to size and weight restrictions during transportation, making transportation convenient. Furthermore, since both components are prefabricated in the factory, they can be directly installed on the construction site without the need for on-site casting of reinforced concrete. The first and second reinforced concrete components are also connected using prefabricated wedge-shaped connectors 3, eliminating the need for secondary grouting at the connection point. This greatly improves construction speed and enhances adaptability to geological conditions.

[0037] In an optional embodiment of this utility model, the first reinforced concrete component 1 is columnar, and a plurality of anchor bolts 11 are connected to the top end face of the columnar first reinforced concrete component 1. The anchor bolts 11 are fixedly connected to the power equipment bracket.

[0038] like Figure 5 As shown, during construction, the second reinforced concrete component 2 is completely buried underground, while the first reinforced concrete component 1 is partially buried underground and partially protrudes above ground. Multiple anchor bolts 11 extend from the top of the portion of the first reinforced concrete component 1 protruding above ground; preferably, four anchor bolts 11 are used. These anchor bolts 11 are connected to the power equipment support, ensuring the power equipment support is stably installed on the ground. The foundation at its base provides support, allowing the power equipment support to resist wind and other external forces, preventing collapse.

[0039] In an optional embodiment of this utility model, each side wall of the first reinforced concrete member 1 of the column is provided with an inverted trapezoidal recess 31.

[0040] In this embodiment, an inverted trapezoidal recess 31 is formed at the bottom of the side wall of the first reinforced concrete component 1, and the inverted trapezoidal recess 31 provides an installation position for the wedge-shaped connector 3. The first reinforced concrete component 1 is preferably a quadrangular prism, and four inverted trapezoidal recesses 31 are preferably provided.

[0041] In an optional embodiment of the present invention, the second reinforced concrete member 2 is in the shape of a boss, and the top end face of the boss-shaped second reinforced concrete member 2 is equal in size to the bottom end face of the first reinforced concrete member 1.

[0042] In this embodiment, as Figure 6As shown, the second reinforced concrete member 2 has a protrusion on its bottom quadrangular prism, and the longitudinal section of the second reinforced concrete member 2 is convex in shape. The top end face of the convex-shaped second reinforced concrete member 2 is exactly the same in size and shape as the bottom end face of the first reinforced concrete member 1.

[0043] In an optional embodiment of this utility model, each side wall of the boss-shaped second reinforced concrete member 2 is provided with a trapezoidal recess 32. The trapezoidal recess 32 is provided in correspondence with the inverted trapezoidal recess 31.

[0044] In this embodiment, as Figure 6 As shown, the top boss sidewall of the second reinforced concrete member 2 is provided with a plurality of trapezoidal recesses 32. The trapezoidal recesses 32 correspond in position to the inverted trapezoidal recesses 31 of the first reinforced concrete member 1, are equal in number, and have opposite opening shapes.

[0045] In an optional embodiment of this utility model, the wedge-shaped connector 3 is disposed inside the positive trapezoidal recess 32 and the inverted trapezoidal recess 31. The number of the wedge-shaped connectors 3 is equal to the number of the positive trapezoidal recesses 32, and the number of the wedge-shaped connectors 3 is equal to the number of the inverted trapezoidal recesses 31.

[0046] In this embodiment, the shape and size of the wedge-shaped connector 3 are exactly the same as the combined size and shape of the trapezoidal recess 32 and the inverted trapezoidal recess 31. The wedge-shaped connector 3 is placed inside the inverted trapezoidal recess 31 and the trapezoidal recess 32, and the wedge-shaped connector 3 engages with the inverted trapezoidal recess 31 and the trapezoidal recess 32, thereby fixing the first reinforced concrete component 1 and the second reinforced concrete component 2 together. Due to the special shape of the wedge-shaped connector 3, the first reinforced concrete component 1 and the second reinforced concrete component 2 can resist the influence of lateral moment, thus maintaining stability. The engaging method of the wedge-shaped connector 3 completely avoids wet work on the construction site, and the first reinforced concrete component 1 and the second reinforced concrete component 2 can be fixedly connected without grouting.

[0047] like Figure 7 and Figure 8 As shown, in an optional embodiment of the present invention, the wedge-shaped connector 3 includes a steel plate mold 34 and high-strength concrete 33, wherein the high-strength concrete 33 is poured inside and outside the steel plate mold 34.

[0048] In this embodiment, the wedge-shaped connector 3 is composed of a precast steel plate mold 34 and high-strength concrete 33. The steel plate mold 34 is welded from steel plates at different angles. The high-strength concrete 33 is poured inside and outside the steel plate mold 34 to strengthen the wedge-shaped connector 3. The high-strength concrete 33 poured on the outside of the steel plate mold 34 also protects the steel plate mold 34. This method of precast steel plate molded with concrete poured inside and outside in this embodiment allows the wedge-shaped connector 3 to have higher strength and adaptability, providing more possibilities for changing different shapes and adapting to different environments.

[0049] The above embodiments of this utility model utilize precast foundations and precast connectors, completely eliminating wet work on the construction site. The time from construction to equipment installation is only one day, resulting in rapid construction. There is no secondary grouting and curing time, effectively improving on-site construction speed, reducing substation power outage time, and also solving the difficulty of concrete pouring in remote areas. In cold regions, the use of precast foundations is unaffected by temperature, meeting the requirement that substation civil engineering work can be carried out at any time, eliminating the need for winter construction plans.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
