[0031] See also Figure 1 , Figure 1FIG2 shows a schematic top view of a foundation structure 500 according to an embodiment of the present application. The foundation structure 500 provided in this embodiment of the present application is applied to a new building 600, which is located on one side of an existing building 100. The new building 600 has a first area 201 and a second area 202, with the first area 201 being closer to the existing building 100 than the second area 202. The foundation structure 500 includes a plurality of first foundation assemblies 10, a plurality of second foundation assemblies 20, and a support assembly 40. The plurality of first foundation assemblies 10 are buried beneath the ground on one side of the existing building 100, and the plurality of second foundation assemblies 20 are buried beneath the ground on one side of the existing building 100. The support assembly 40 includes a plurality of first members 41 and a plurality of second members 42. The plurality of first members 41 are disposed in the first area 201 and fixedly connected to the plurality of first foundation assemblies 10 in a one-to-one relationship. The plurality of second members 42 are disposed in the second area 202 and fixedly connected to the plurality of second foundation assemblies 20 in a one-to-one relationship.

[0032] The first area 201 refers to the area between the equipment construction boundary line 200 and the existing building outer contour line 101; the second area 202 refers to the area on the side of the equipment construction boundary line 200 away from the existing building 100; the equipment construction boundary line 200 is the boundary within which the side-pressing pile equipment can enter the construction site and carry out construction. That is, the side-pressing pile equipment cannot be used for construction in the first area 201, while the side-pressing pile equipment can be used for construction in the second area 202. The equipment construction boundary line 200 is determined by the size and performance of the side-pressing pile equipment actually selected. For example, in this embodiment, the constructible boundary line is 1500 mm from the side of the existing building outer contour line 101 away from the existing building 100.

[0033] Please also refer to Figure 2 , Figure 2 Shown Figure 1 In the cross-sectional schematic diagram along BB, in some embodiments, the first foundation component 10 includes a first cantilevered ground beam 11 and a first pile foundation pedestal 12, the first cantilevered ground beam 11 is buried under the ground of the first area 201, and the first pile foundation pedestal 12 is buried under the ground of the second area 202 and is located at the end of the first cantilevered ground beam 11 away from the existing building 100; the first pile foundation pedestal 12 abuts against the first cantilevered ground beam 11, and the first cantilevered ground beam 11 has an end close to the existing building 100 and an end away from the existing building 100, and one end face of the first pile foundation pedestal 12 abuts against the end face of the first cantilevered ground beam 11 away from the existing building 100; the first component 41 is arranged at the end of the first cantilevered ground beam 11 close to the existing building 100.

[0034] It is understood that cantilevered ground beams are typically cast without the need for construction equipment. The first cantilevered ground beam 11 is positioned below the ground in the first area 201, and the first component 41 is positioned at the end of the first cantilevered ground beam 11 closest to the existing building 100. This allows the first component 41 to be as close to the existing building 100 as possible, eliminating the need to distance it from the existing building 100 to provide sufficient construction space for the construction equipment. The first pile foundation cap 12 is buried below the ground in the second area 202, with one end face of the first pile foundation cap 12 abutting against the end face of the first cantilevered ground beam 11 at the end distant from the existing building 100. This allows the first pile foundation cap 12 to both distribute the load on the first cantilevered ground beam 11 and maintain a distance from the existing building 100, thereby providing sufficient construction space for the side-pressing pile equipment.

[0035] In some embodiments, the height of the first pile foundation cap 12 is greater than or equal to the height of the first cantilevered ground beam 11. This increases the contact area between the first pile foundation cap 12 and the first cantilevered ground beam 11, allowing the end surface of the first cantilevered ground beam 11 to stably abut against the end surface of the first pile foundation cap 12, thereby increasing the bearing capacity of the first pile foundation cap 12 and enhancing structural stability. In this embodiment, the height of the first pile foundation cap 12 is equal to the height of the first cantilevered ground beam 11, both being 1800 mm.

[0036] In some embodiments, the size of the portion of the first cantilevered ground beam 11 outside the first component 41 is 200 mm to 300 mm, so that the first component 41 can be stably installed on the first cantilevered ground beam 11 .

[0037] Please also refer to Figure 3 , Figure 3 Shown Figure 2 As shown in the enlarged schematic diagram at point D in the figure, in some embodiments, the first foundation assembly 10 further includes a first connector 13. The first connector 13 includes a first fixing portion 131 and a first connecting portion 132. The first fixing portion 131 is disposed inside the first cantilevered ground beam 11, while the first connecting portion 132 is connected to the first fixing portion 131 and disposed outside the first cantilevered ground beam 11. The first component 41 includes a first base 411 and a first body 412. The first base 411 is disposed in the first cantilevered ground beam 11 and fixedly connected to the first connecting portion 132. The first body 412 is fixedly disposed on the first base 411. In some embodiments, the first connector 13 is a steel bar or anchor bolt pre-embedded in the first cantilevered ground beam 11. Part of the steel bar or anchor bolt is located on the outer surface of the first cantilevered ground beam 11, facilitating the connection between the first cantilevered ground beam 11 and the first component 41. Furthermore, the fact that part of the steel bar or anchor bolt is pre-embedded in the first cantilevered ground beam 11 enhances the stability of the connection between the first cantilevered ground beam 11 and the first component 41.

[0038] In some embodiments, the height of the first cantilevered ground beam 11 is greater than the length of the first fixing portion 131 of the first connecting member 13 , so that the first connecting member 13 is stably disposed on the first cantilevered ground beam 11 .

[0039] In some embodiments, the second foundation assembly 20 includes a second pile cap 21 and a plurality of second reinforcement members 22. The second pile cap 21 is buried beneath the ground in a second area 202. The plurality of second reinforcement members 22 are disposed at the bottom of the second pile cap 21. The second member 42 is disposed on the second pile cap 21. It is understood that in the second area 202 where construction can be performed using a side-pressing pile device, the second pile cap 21 can be directly disposed below the ground using the side-pressing pile device to connect with the second member 42. This allows the second pile cap 21 to more effectively transfer loads and enhance the stability of the foundation structure 500. Furthermore, the plurality of second reinforcement members 22 disposed at the bottom of the second pile cap 21 effectively distributes and transfers the load of the second pile cap 21. In some embodiments, the second reinforcement members 22 are prestressed concrete pipe piles. Prestressed concrete pipe piles have the characteristics of high bearing capacity, good stability, and low settlement, which helps to improve the overall structural stability of the second foundation assembly 20. In addition, prestressed concrete pipe piles are usually prefabricated in factories and can be directly installed during on-site construction, thereby shortening the construction period and improving construction efficiency.

[0040] In some embodiments, the second foundation assembly 20 further includes a second connector 23, which is disposed on the second pile foundation cap 21 and is used to connect the second pile foundation cap 21 to the second component 42. In this embodiment, the second connector 23 has the same structure as the first connector 13 and is not described in detail here.

[0041] Please also refer to Figure 4 , Figure 4 Shown Figure 1In a cross-sectional view along line AA, in some embodiments, an existing building 100 includes a first peripheral structure 102, a second peripheral structure 103, and a third peripheral structure 104. The first peripheral structure 102, the second peripheral structure 103, and the third peripheral structure 104 are sequentially connected and enclose the existing building 100, forming a "concave" shape when viewed from above. The angle formed between the first peripheral structure 102 and the second peripheral structure 103 is 90°, and the angle formed between the third peripheral structure 104 and the second peripheral structure 103 is also 90°. The quarter-circle area formed between the first peripheral structure 102 and the second peripheral structure 103, and the quarter-circle area formed between the third peripheral structure 104 and the second peripheral structure 103, are both referred to as concave angle areas 203. The radius of the quarter-circle area is determined by the size and performance of the pile driving equipment. The radius of the quarter-circle area is less than the distance required for the pile driving equipment to enter the construction site and perform construction. That is, the side pile driving equipment cannot be used for construction within the concave angle areas 203. The foundation structure 500 also includes a plurality of third foundation assemblies 30, which are buried under the ground on one side of the existing building 100; the support assembly 40 also includes a plurality of third components 43, which are located in the concave corner area 203 formed by the existing building 100 and are fixedly connected to the plurality of third foundation assemblies 30 one by one.

[0042] In some embodiments, the third foundation assembly 30 includes a bidirectional cantilevered ground beam 31, a third pile foundation cap 33, and a fourth pile foundation cap 34. The bidirectional cantilevered ground beam 31 is buried below the ground in the concave corner area 203. The bidirectional cantilevered ground beam 31 includes a second cantilevered ground beam 312 and a third cantilevered ground beam 313. The second cantilevered ground beam 312 and the third cantilevered ground beam 313 are perpendicular to each other in the horizontal plane and are integrally formed into a "cross" structure. The third pile foundation cap 33 is disposed at the end of the second cantilevered ground beam 312 away from the existing building 100 and abuts the second cantilevered ground beam 312. The second cantilevered ground beam 312 has an end proximal to the existing building 100 and an end away from the existing building 100. One end face of the third pile foundation cap 33 abuts the end face of the second cantilevered ground beam 312 away from the existing building 100. The fourth pile foundation cap 34 is disposed at the end of the third cantilevered ground beam 313 away from the existing building 100 and abuts the third cantilevered ground beam 313. The third cantilevered ground beam 313 has one end proximal to the existing building 100 and one end distal to the existing building 100. One end face of the fourth pile foundation cap 34 abuts the end face of the third cantilevered ground beam 313 distal to the existing building 100. The third member 43 is disposed at either the end of the second cantilevered ground beam 312 proximal to the existing building 100 or the end of the third cantilevered ground beam 313 proximal to the existing building 100.

[0043] It will be appreciated that cantilevered ground beams are typically cast. By burying the bidirectional cantilevered ground beam 31 beneath the ground in the concave corner area 203, the third component 43 can be placed as close to the existing building 100 as possible, eliminating the need to move it away from the existing building 100 to provide sufficient space for construction equipment. Furthermore, the third and fourth pile foundation caps 33 and 34 can distribute the load on the bidirectional cantilevered ground beam 31, thereby increasing the bearing capacity of the third foundation assembly 30.

[0044] In some embodiments, the extension direction of the second cantilevered ground beam 312 is parallel to the extension direction of the third peripheral structure 104 of the existing building 100, and the extension direction of the third cantilevered ground beam 313 is parallel to the extension direction of the second peripheral structure 103 of the existing building 100; the length of the second cantilevered ground beam 312 is greater than the radius of the concave angle area 203, and the end of the third pile foundation pedestal 33 that abuts the second cantilevered ground beam 312 is located near the concave angle area 203; the length of the third cantilevered ground beam 313 is greater than the radius of the concave angle area 203, and The end of the fourth pile foundation pedestal 34 that abuts the third cantilever ground beam 313 is arranged near the concave angle area 203; this achieves the purpose of reducing the length of the second cantilever ground beam 312 and the third cantilever ground beam 313, thereby enhancing the bearing capacity of the second cantilever ground beam 312 and the third cantilever ground beam 313, reducing the bending moment exerted on the second cantilever ground beam 312 and the third cantilever ground beam 313, and reducing the risk of deformation of the second cantilever ground beam 312 and the third cantilever ground beam 313, so as to increase the stability of the overall structure of the bidirectional cantilever ground beam 31 and the third foundation assembly 30.

[0045] In some embodiments, the third pile foundation pedestal 33 and the fourth pile foundation pedestal 34 are both long strip structures, the length direction of the third pile foundation pedestal 33 is parallel to the length direction of the second cantilevered ground beam 312, and the fourth pile foundation pedestal 34 is parallel to the length direction of the third cantilevered ground beam 313, so that the third pile foundation pedestal 33 can effectively disperse the load of the second cantilevered ground beam 312, and the fourth pile foundation pedestal 34 can effectively disperse the load of the third cantilevered ground beam 313, thereby reducing the concentrated stress area and improving the stability of the overall structure of the third foundation component 30.

[0046] In some embodiments, the third foundation assembly 30 further includes a plurality of reinforcements 35, which are buried within the soil of the concave angle region 203 formed by the existing building 100 and located below the bidirectional cantilevered ground beam 31. The reinforcements 35 located at the bottom of the bidirectional cantilevered ground beam 31 abut against the lower surface of the bidirectional cantilevered ground beam 31. The plurality of reinforcements 35 are used to reinforce the soil in the concave angle region 203 and reduce the vertical deformation of the bidirectional cantilevered ground beam 31. In some embodiments, the reinforcements 35 are high-pressure jet grouting piles, which are used to perform foundation treatment on the soil in the concave angle region 203, increasing the compression modulus of the original soil to ensure that the vertical deformation of the third component 43 is within a controllable range. In some embodiments, the diameter of the high-pressure jet grouting piles is 500 mm, and the spacing between two adjacent high-pressure jet grouting piles is 900 mm, thereby improving the bearing capacity of the third foundation assembly 30.

[0047] In some embodiments, the third foundation assembly 30 further includes a third connector 36, which is disposed on the bidirectional cantilevered ground beam 31 and is used to connect the bidirectional cantilevered ground beam 31 and the third member 43. In this embodiment, the third connector 36 has the same structure as the first connector 13 and is not described in detail here.

[0048] The foundation structure 500 provided in the present application is provided with a support assembly 40, multiple first foundation assemblies 10, multiple second foundation assemblies 20 and multiple third foundation assemblies 30. The support assembly 40 includes multiple first components 41, multiple second components 42 and multiple third components 43, wherein the multiple first components 41 are arranged in the first area 201 and are fixedly connected to the multiple first foundation assemblies 10 one by one, the multiple second components 42 are arranged in the second area 202 and are fixedly connected to the multiple second foundation assemblies 20 one by one, and the multiple third components 43 are arranged in the concave corner area 203 and are fixedly connected to the multiple third foundation assemblies 30 one by one, thereby making full use of the construction conditions in different areas and making the vertical components as close to the existing building 100 as possible. There is no need to set the lower foundation away from the existing building 100 in order to create a construction site.

[0049] The present application also provides a new building 600, comprising a plurality of horizontal members, a roof structure, and the aforementioned base structure 500. The plurality of horizontal members are connected to the base structure 500 to form a frame structure, and the roof structure is disposed on top of the frame structure. The new building 600 can be constructed adjacent to the existing building 100 without requiring a large-span cantilever structure, thereby reducing construction costs and ease of construction difficulty.
