Description

Technical Field

[0001] The utility model relates to the technical field of power station energy storage, in particular to a prefabricated energy storage foundation. Background Art

[0002] Energy is the foundation of human development. While traditional non-renewable energy sources like coal and oil provide convenience in daily life and production, they also emit significant amounts of greenhouse gases. In recent years, renewable energy sources such as wind power and photovoltaics have experienced rapid growth, reducing greenhouse gas emissions and preventing the worsening of environmental problems. Energy storage, as a flexible resource, can ensure the absorption of renewable energy, enhance the flexibility of the power system, and support its safe and stable operation.

[0003] Currently, the foundations of energy storage equipment are conventionally constructed using cast-in-place concrete. This construction method not only cannot guarantee construction quality, but is also greatly affected by the weather at the construction site, has a long construction period, and has a significant impact on the environment. In addition, the amount of materials used is far greater than that of prefabricated products, resulting in wasted wooden molds and a large amount of labor, resulting in a relatively high overall cost.

[0004] For traditional cast-in-place concrete foundations, existing technology divides the pile foundation, pedestal and ground beam into two blocks, upper and lower. The precast piles serve as the lower block, and the precast pedestal and ground beams serve as the upper block. They are prefabricated in the factory and then installed on the construction site. This improvement will cause positioning deviations after the precast piles are driven in, which in turn affects the connection between the precast piles and the upper module. Utility Model Content

[0005] In order to improve the problem of positioning deviation after the prefabricated piles are driven in the prior art, thereby affecting the connection between the prefabricated piles and the upper module, the present invention provides a prefabricated energy storage foundation.

[0006] The utility model provides a prefabricated energy storage foundation, which adopts the following technical solutions:

[0007] A prefabricated energy storage foundation includes several steel sleeves, each of which is provided with a prefabricated pile. The top of the prefabricated pile is connected to an upper prefabricated foundation, and supporting steel beams are connected between adjacent steel sleeves.

[0008] By adopting the above technical solution, the precast piles are limited by setting a number of steel sleeves, and the steel sleeves are connected by supporting steel beams. In this way, the eccentricity of the precast piles is ensured to be within the control error range during the driving process, and the precast piles are prevented from being excessively deviated during the driving process, which may affect their connection with the upper precast foundation.

[0009] Optionally, a plurality of the supporting steel beams are provided, and all of the supporting steel beams are I-shaped supporting steel beams.

[0010] By adopting the above technical solution, since the I-shaped supporting steel beam has high strength and pressure resistance, it can withstand large loads and pressures and is not easily deformed, thereby being able to better support the steel sleeve.

[0011] Optionally, the angle between adjacent supporting steel beams is 90°.

[0012] By adopting the above technical solution, the stability and strength of the supporting steel beam structure can be ensured, and the force can be better dispersed when bearing weight or external force, avoiding deformation or damage of the supporting steel beam caused by excessive force at a single point, thereby making the supporting steel beam stronger and more durable.

[0013] Optionally, surfaces of several of the supporting steel beams are coated with a paint layer.

[0014] By adopting the above technical solution, the surface of the supporting steel beam is prevented from rusting due to long-term exposure to the air, the anti-corrosion performance of the supporting steel beam is improved, and the service life of the supporting steel beam is extended.

[0015] Optionally, a prefabricated pile embedded part is provided on the top of the prefabricated pile, and an upper prefabricated foundation embedded part is provided on the bottom of the upper prefabricated foundation.

[0016] By adopting the above technical solution, it is only necessary to weld the prefabricated pile embedded parts and the upper prefabricated foundation embedded parts on site to ensure that the prefabricated pile and the upper prefabricated foundation are effectively connected.

[0017] Optionally, the diameter of the steel sleeve is slightly larger than the diameter of the precast pile.

[0018] By adopting the above technical solution, it is possible to ensure that the eccentricity of the prefabricated pile is within the control error range during the driving process.

[0019] In summary, the present invention has at least one of the following beneficial effects:

[0020] The precast piles are limited by setting up several steel sleeves, and each steel sleeve is connected by a supporting steel beam. This ensures that the eccentricity of the precast piles is within the control error range during the driving process, and tries to avoid excessive deviation of the precast piles during the driving process, which affects their connection with the upper precast foundation.

[0021] By setting precast pile embedded parts on the top of the precast pile and setting upper precast foundation embedded parts on the bottom of the upper precast foundation, during installation, it is only necessary to weld the precast pile embedded parts and the upper precast foundation embedded parts on site to ensure that the precast pile and the upper precast foundation are effectively connected.

[0022] Precast piles and upper precast foundations are fully prefabricated, eliminating the need for on-site formwork. The concrete pouring and curing steps can significantly reduce the construction period. Compared with on-site pouring, it has less impact on the surrounding environment and requires less technical and management skills from construction workers. It can also reduce the dust, waste materials, tools, and vehicles brought about by on-site construction that are difficult to manage, thus meeting the requirements of green and civilized construction.

[0028] The following is combined with Figure 1-3 The utility model is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1 The present invention provides an embodiment of a prefabricated energy storage foundation, comprising a plurality of steel sleeves 1, each of which is provided with a prefabricated pile 2. The diameter of the steel sleeves 1 is slightly larger than the diameter of the prefabricated pile 2. This ensures that the eccentricity of the prefabricated pile 2 is within a control error range during the driving process.

[0030] Please refer to the attached figure in the instruction manual Figure 2The top of the precast pile 2 is connected to the upper precast foundation 4, the top of the precast pile 2 is provided with a precast pile embedded part 5, and the bottom of the upper precast foundation 4 is provided with an upper precast foundation embedded part 6. The precast pile embedded part 5 and the upper precast foundation embedded part 6 both include precast steel plates and precast steel bars. Two groups of precast steel plates are respectively connected to the top of the precast pile 2 and the bottom of the upper precast foundation 4. Two groups of precast steel bars are respectively embedded in the interior of the precast pile 2 and the upper precast foundation 4. The precast steel bars are arranged in a circular shape with respect to the center of the precast steel plates. The spacing between two adjacent precast steel bars on the precast pile embedded part 5 is 100 mm, and the spacing between two adjacent precast steel bars on the upper precast foundation embedded part 6 is 50 mm. It is only necessary to weld the precast pile embedded part 5 and the upper precast foundation embedded part 6 on site to ensure that the precast pile 2 and the upper precast foundation 4 are effectively connected.

[0031] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3 Adjacent steel sleeves 1 are connected with supporting steel beams 3. There are several supporting steel beams 3, all of which are I-shaped supporting steel beams. Since the I-shaped supporting steel beams have high strength and pressure resistance, they can withstand large loads and pressures and are not easily deformed, thereby better supporting the steel sleeves 1.

[0032] Please refer to the attached figure in the instruction manual Figure 1 , the angle between adjacent support steel beams 3 is 90°. This ensures the stability and strength of the support steel beam 3 structure, better disperses the force when bearing weight or external force, avoids deformation or damage of the support steel beam 3 due to excessive force at a single point, and makes the support steel beam 3 stronger and more durable. The surfaces of several support steel beams 3 are coated with a paint layer. This prevents the surface of the support steel beam 3 from rusting due to long-term exposure to the air, improves the anti-corrosion performance of the support steel beam 3, and thus extends the service life of the support steel beam 3.

[0033] Working principle: When in use, after the upper prefabricated foundation 4 and the prefabricated pile 2 are transported to the site, a steel sleeve 1 is set at the positioning center of the prefabricated pile 2 before the prefabricated pile 2 is driven in, and the prefabricated pile 2 is limited by the steel sleeve 1. After the steel sleeve 1 is installed, the prefabricated piles 2 are driven in sequence, and the positions of the prefabricated piles 2 are detected. After the deviation of the prefabricated piles 2 meets the specification requirements, the upper prefabricated foundation 4 prefabricated in the factory is hoisted to the top of the prefabricated pile 2, and the prefabricated pile embedded parts 5 and the upper prefabricated foundation embedded parts 6 are welded to connect the prefabricated pile 2 and the upper prefabricated foundation. The prefabricated piles 2 and the upper prefabricated foundation 4 are connected. Since the prefabricated piles 2 and the upper prefabricated foundation 4 are fully prefabricated, the construction quality of each component can be guaranteed and is not affected by the weather. Since the prefabricated components can save on-site formwork, the concrete pouring and maintenance steps can greatly reduce the construction period, and compared with the on-site pouring, it has little impact on the surrounding environment, and has lower requirements on the technical level and management level of the construction personnel. It can reduce the dust, waste materials, tools, and vehicles brought by on-site construction that are difficult to manage, and meets the requirements of green and civilized construction. The steel sleeve 1 can be disassembled and reused to reduce costs.

[0034] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
