Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation structure technology, and specifically provides an adjustable prefabricated foundation. Background Technology

[0002] Prefabricated substations, also known as box-type substations or prefabricated transformer substations, are a new type of substation that emerged after civil engineering substations. They are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering distribution rooms and substations, becoming a new type of complete power distribution equipment. Currently, most box-type substations in China use prefabricated containers, but the foundations for installing these prefabricated containers are generally still constructed using traditional civil engineering methods such as on-site excavation, requiring a large amount of earthwork excavation and backfilling. In severe summer weather or the rainy season, construction becomes more difficult, with increased wet work; in low-temperature winter environments, special construction measures are required to ensure project quality. Therefore, the existing prefabricated container foundation setting method results in a long construction cycle for the entire box-type substation, and the quality of the foundation, especially the levelness of the bottom surface after the prefabricated container is installed, is difficult to control, which has become a major pain point in the construction of prefabricated substations. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an adjustable prefabricated foundation. By prefabricating the foundation in advance, it solves the problems of extensive earthwork excavation and backfilling, significantly reducing the amount of on-site construction work at substations, lowering construction difficulty, and shortening the project cycle.

[0004] The technical solution of this utility model is as follows:

[0005] An adjustable prefabricated cabin foundation includes multiple embedded modules and pillars corresponding to each embedded module. The bottom of each pillar is mounted on an embedded module, and the top of each pillar supports the prefabricated cabin. A height adjustment component is provided between the pillar and the embedded module.

[0006] In this scheme, pre-embedded modules that serve as the foundation for the prefabricated cabin are prefabricated. Only the pre-embedded modules need to be installed, eliminating the need for extensive earthwork excavation and backfilling. The prefabricated cabin can then be directly hoisted over to connect with the support columns and installed, significantly reducing the amount of on-site construction at the substation, lowering the construction difficulty, and shortening the project cycle. Each support column supporting the prefabricated cabin can have its support height adjusted relative to the other column using height adjustment components, avoiding the problem of uneven installation ground causing the prefabricated cabin installation surface to be uneven. The levelness of the bottom surface of the prefabricated cabin can also be strictly controlled by fine-tuning the height adjustment components.

[0007] Preferably, the bottom of the support column is provided with a lower column connecting plate, and multiple fixing bolts are fixedly extended from the surface of the pre-embedded module. The fixing bolts are inserted into the lower column connecting plate, and the height adjustment component includes a height adjustment plate disposed between the pre-embedded module and the lower column connecting plate.

[0008] In this scheme, the fixing bolts are pre-cast into the pre-embedded module during the production process. When the pre-embedded module is buried in the soil, it is only necessary to ensure that the fixing bolts extend out of the ground to complete the bolting connection between the support and the pre-embedded module. Furthermore, if the prefabricated cabin needs to be disassembled and moved later, the foundation does not need to be damaged. The prefabricated cabin can be moved by releasing the bolting connection.

[0009] Since the pre-embedded modules need to be embedded in designated locations in advance, there will inevitably be errors in the accuracy of their embedding positions. Therefore, in order to ensure the accuracy of the installation position of the prefabricated cabin, the lower column connecting plate is provided with multiple first strip holes. The positions of the strip holes are adapted to the arrangement of the fixing bolts. The first strip holes correspond one-to-one with the fixing bolts. After the fixing bolts are inserted into the lower column connecting plate, it can also be moved and adjusted along the length of the first strip holes. After adjustment to the appropriate position, it is then positioned and fixed by tightening the lock nuts.

[0010] Similarly, preferably, the top of the support column is provided with an upper column connecting plate, which is bolted to the bottom of the precast cabin. The upper column connecting plate is provided with a plurality of second strip-shaped holes, so that the position of the upper column connecting plate can be finely adjusted along the length direction of the second strip-shaped holes when it is bolted to the bottom plate of the precast cabin.

[0011] Preferably, the length directions of the first and second strip holes are perpendicular to each other. The length directions of the first and second strip holes are adjustable to ensure that even if there is a certain error in the installation of the pre-embedded module, the support column can be accurately connected to the predetermined position of the prefabricated cabin.

[0012] For some large prefabricated cabins, in order to ensure that the height adjustment plate has sufficient load-bearing capacity while reducing costs as much as possible, the height adjustment plate preferably includes multiple pads. The pads are provided with through holes that are adapted to the arrangement of the fixing bolts. Each support is adjusted individually according to the actual flatness of the ground. By setting pads of different thicknesses and numbers, the support height of all supports is made to be on the same horizontal plane.

[0013] For some small prefabricated cabins, where the weight is within the allowable range, preferably, the height adjustment plate includes a base plate and a support plate. The base plate and the support plate are provided with through holes that match the arrangement of the fixing bolts. A stud with a support plate is provided between the base plate and the support plate. The stud is threaded into the embedded module and a positioning nut is threaded onto the stud.

[0014] In this scheme, the support column is supported by adjusting the studs. The height of the studs is preset to control the support plate to press against the support plate. The support plate provides an installation surface for the lower column connecting plate of the support column. The studs are positioned by rotating the positioning nut to press against the base plate.

[0015] Due to the stress on the bolts and the position of the fixing bolts, it is difficult to adjust the height of the studs after the prefabricated cabin is installed. However, it is difficult to determine the required height of the studs and the locking strength of the positioning nuts before the prefabricated cabin is placed. Therefore, preferably, the base plate is provided with multiple pre-adjusting bolts, which surround the fixing bolts and pass through the support plate. The height of the support plate on the pre-adjusting bolts is locked by double nuts.

[0016] In this scheme, by adjusting the height of the support plates before hoisting the prefabricated module, ensuring that the support plates on each embedded module are on the same horizontal plane, the horizontality of the subsequent support columns and prefabricated module installation can be guaranteed. Furthermore, after the double nuts on the pre-adjusting bolts are positioned and fixed, the studs can be turned in advance to allow the support plate to press tightly against the support plate, while simultaneously tightening the fixing nuts. This allows the studs to bear force in advance, preventing situations where, after the prefabricated module is installed and the studs are under force, it is discovered that the studs or fixing nuts were not turned in place, leading to errors in height conditions.

[0017] Preferably, a baffle is provided between the pillars.

[0018] Preferably, a side extension plate is provided next to the support column, and the side extension plate is provided with vertical strip mounting holes. The enclosure plate includes a main plate and a sub-plate. The main plate is disposed between the support columns through the mounting holes, and the sub-plate is disposed at the bottom of the main plate to cover the gap between the main plate and the ground.

[0019] In this solution, by setting up enclosures, animals can be prevented from entering the bottom of the prefabricated compartment and damaging the cables, and wind and sand can also be prevented from entering the bottom of the prefabricated compartment and affecting the safety of the cables.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model prefabricates the embedded modules that serve as the foundation for the prefabricated cabin in advance. Only the embedded modules need to be buried and installed, eliminating the need for extensive earthwork excavation and backfilling. The prefabricated cabin can then be directly hoisted over to connect with the support columns and installed, which greatly reduces the amount of on-site construction work in the substation, lowers the construction difficulty, and shortens the project cycle.

[0022] 2. In this utility model, the support height of each pillar of the precast container can be relatively adjusted by the height adjustment component, which avoids the problem of uneven installation ground causing the precast container installation surface to be uneven. It can also strictly control the levelness of the bottom surface of the precast container by fine-tuning the height adjustment component. Attached Figure Description

Detailed Implementation

[0031] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0032] Example 1:

[0033] An adjustable prefabricated cabin foundation, such as Figure 1 As shown, it includes multiple pre-embedded modules 1 and pillars 2 corresponding to each pre-embedded module 1. The bottom of the pillar 2 is set on the pre-embedded module 1, and the top of the pillar 2 supports the prefabricated cabin. An adjustment component 3 is provided between the pillar 2 and the pre-embedded module 1.

[0034] Specifically, the bottom of the support column 2 is supported by steel and equipped with a lower column connecting plate 21. Multiple fixing bolts 11 extend from the surface of the pre-embedded module 1, preferably anchor bolts, and are arranged at the four corners or around the circumference to allow for subsequent flange connections. The fixing bolts 11 are inserted into the lower column connecting plate 21, and the height adjustment assembly 3 includes a height adjustment plate disposed between the pre-embedded module 1 and the lower column connecting plate 21.

[0035] In this embodiment, the pre-embedded module 1, which serves as the foundation for the prefabricated cabin, is prefabricated. Only the pre-embedded module 1 needs to be installed beforehand, eliminating the need for extensive excavation and backfilling. The prefabricated cabin can then be directly hoisted over to connect with the support column 2 and installed, significantly reducing on-site construction work at the substation, lowering construction difficulty, and shortening the project cycle. Each support column 2 supporting the prefabricated cabin can have its support height adjusted relative to the support height using the height adjustment component 3, preventing uneven ground from causing the prefabricated cabin installation surface to be uneven. The height adjustment component 3 also allows for strict control of the levelness of the prefabricated cabin's bottom surface. Furthermore, the fixing bolts 11 are pre-cast into the pre-embedded module 1 during production. When the pre-embedded module 1 is buried in the soil, simply ensuring that the fixing bolts 11 extend above the ground completes the bolting connection between the support column 2 and the pre-embedded module 1. Moreover, if the prefabricated cabin needs to be disassembled and moved later, the foundation does not need to be damaged; the prefabricated cabin can be moved simply by releasing the bolts.

[0036] Example 2:

[0037] Based on Example 1, since the pre-embedded module 1 needs to be pre-embedded in a designated location, the accuracy of its embedding position will inevitably have errors. Therefore, in order to ensure the accuracy of the prefabricated cabin installation position, such as... Figure 5 As shown, the lower column connecting plate 21 is provided with a plurality of first strip-shaped holes 23. The positions of the strip-shaped holes are adapted to the arrangement of the fixing bolts 11. The first strip-shaped holes 23 correspond one-to-one with the fixing bolts 11. After the fixing bolts 11 pass through the lower column connecting plate 21, it can also be moved and adjusted along the length direction of the first strip-shaped holes 23. After adjustment, it is fixed by locking the nuts. Similarly, the top of the support column 2 is provided with an upper column connecting plate 22. The upper column connecting plate 22 is bolted to the bottom of the prefabricated cabin. The upper column connecting plate 22 is provided with a plurality of second strip-shaped holes 24, allowing the upper column connecting plate 22 to be finely adjusted in position along the length direction of the second strip-shaped holes 24 when bolted to the bottom plate 32 of the prefabricated cabin.

[0038] Furthermore, the length directions of the first strip hole 23 and the second strip hole 24 are perpendicular to each other. The length directions of the first strip hole 23 and the second strip hole 24 are adjustable, which ensures that even if there is a certain error in the installation of the pre-embedded module 1, the support column 2 can be accurately connected to the predetermined position of the prefabricated cabin.

[0039] Example 3:

[0040] Based on Embodiment 1 and Embodiment 2 described above, for some large prefabricated cabins, to ensure that the height adjustment plate has sufficient load-bearing capacity while minimizing costs, the following measures can be taken: Figure 1 and Figure 2 As shown, the height adjustment plate includes multiple pads 31. The pads 31 are provided with through holes that match the arrangement of the fixing bolts 11. Each support column 2 is adjusted individually according to the actual flatness of the ground. By setting pads 31 of different thicknesses and numbers, the support height of all support columns 2 is on the same horizontal plane.

[0041] Specifically, in Embodiment 1, the fixing bolts 11 are arranged in a circular or square pattern, and the pad 31 can directly use a flange corresponding to the flange hole and the fixing bolt, providing stronger support through the flange.

[0042] Example 4:

[0043] This embodiment differs from Embodiment 3 in that it addresses some small prefabricated modules whose weight is within permissible limits, such as... Figure 3 and Figure 4 As shown, the height adjustment plate includes a base plate 32 and a support plate 33. The base plate 32 and the support plate 33 are provided with through holes that match the arrangement of the fixing bolts 11. A stud 34 with a support plate 33 is provided between the base plate 32 and the support plate 33. The stud 34 is threaded into the pre-embedded module 1, and a positioning nut 35 is threaded onto the stud 34.

[0044] In this embodiment, the base plate 32 is set on the surface of the embedded unit, and the stud 34 is set in the middle of the embedded unit. The stud 34 provides support for the support column 2 by adjusting the stud 34. The height of the stud 34 is preset to control the support plate 33 to press against the support plate 33. The support plate 33 provides an installation surface for the lower column connecting plate 21 of the support column 2. The stud 34 is positioned by rotating the positioning nut 35 to abut against the base plate 32. The positioning nut 35 has a fixing bolt 11 on its periphery, so the positioning nut 35 has an auxiliary lug 37 on its side to facilitate the installer to rotate and lock the positioning nut 35.

[0045] It should be noted that, due to the stress on the bolts and the position of the fixing bolts 11, it is difficult to adjust the height of the studs 34 after the prefabricated cabin is installed. Before the prefabricated cabin is placed, it is also difficult to determine the required height of the studs 34 and the locking strength of the positioning nuts 35. Therefore, multiple pre-adjustment bolts 36 are provided on the base plate 32. The pre-adjustment bolts 36 surround the fixing bolts 11 and pass through the support plate 33. The height of the support plate 33 on the pre-adjustment bolts 36 is locked by double nuts. That is, two nuts on the same pre-adjustment bolt 36 are placed with one nut above the support plate 33 and one nut below the support plate 33, and are tightened relative to each other.

[0046] Specifically, before hoisting the prefabricated cabin, the height of the support plate 33 is manually adjusted. Once the height of the support plate 33 is appropriate, the double nuts on the pre-adjustment bolt 36 are used to position the height of the support plate 33, ensuring that the support plates 33 on each embedded module 1 are on the same horizontal plane, thus ensuring the horizontality of the subsequent installation of the support column 2 and the prefabricated cabin. After being positioned and fixed by the double nuts on the pre-adjustment bolt 36, the stud 34 is rotated to make the support plate 33 on the stud 34 press tightly against the support plate 33. At this time, the fixing nut is tightened to complete the height adjustment of the height adjustment component 3, allowing the stud 34 to bear force in advance, avoiding the situation where the stud 34 or fixing nut is not rotated properly after the prefabricated cabin is installed, resulting in errors in height conditions. Then, the support column 2 is connected by the fixing bolt 11. When installing the support column 2, the nuts on the fixing stud 34 can be left untightened initially. The position can be adjusted through the first and second elongated holes before tightening the nuts, finally completing the connection between the prefabricated cabin and the support column 2.

[0047] Example 5:

[0048] Based on the above embodiments, such as Figures 1 to 4 As shown, a baffle plate 4 is installed between the support columns 2. Specifically, a side extension plate 25 is provided on the side of each support column 2, and the side extension plate 25 is provided with vertical strip mounting holes. The baffle plate 4 includes a main plate 41 and a secondary plate 42. The main plate 41 is installed between the support columns 2 through the mounting holes, and the secondary plate 42 is located at the bottom of the main plate 41 to cover the gap between the main plate 41 and the ground. Specifically, both the secondary plate 42 and the main plate 41 are provided with mutually perpendicular elongated holes to ensure that the secondary plate 42 can be angled according to the bottom height to avoid interference. By setting up the baffle plate 4, animals can be prevented from entering the bottom of the prefabricated compartment and damaging the cables, and wind and sand can also be prevented from entering the bottom of the prefabricated compartment and affecting the safety of the cables.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
