Description

Technical Field

[0001] This utility model relates to the field of foundation pit construction technology, and in particular to an arc-shaped prefabricated steel enclosure structure and fence system. Background Technology

[0002] With the rapid development of the national economy, urban rail transit and construction projects have developed rapidly, and foundation pit protection engineering in foundation engineering has become the most important. At present, the commonly used foundation pit protection methods include diaphragm walls, interlocking piles, cast-in-place piles, Larssen steel sheet piles and cement-soil mixing piles. Most of these methods require a large amount of concrete or generate a large amount of waste mud during construction, which consumes a lot of resources and has a great impact on the environment.

[0003] Taking Larssen sheet piles as an example, existing technologies mostly use vibratory hammers to press the piles into the hole, which can lead to problems such as difficulty in ensuring verticality, low stiffness, poor interlocking at the joints, poor water-proofing effect, and difficulty in insertion. Utility Model Content

[0004] The purpose of this utility model is to provide an arc-shaped prefabricated steel enclosure structure and fence system to address the above-mentioned shortcomings. This solves the problems in the existing technology where steel sheet piles are mostly driven into the hole with a vibratory hammer, which can lead to issues such as difficulty in ensuring verticality, low rigidity, poor interlocking at the locking point, poor water-proofing effect, and difficulty in insertion.

[0005] This utility model is achieved through the following solution:

[0006] An arc-shaped prefabricated steel enclosure structure includes, but is not limited to, a first support part, a second support part, and a central support part. The first support part and the second support part are symmetrically arranged on both sides of the central support part. Limiting parts for supporting the central support part are provided on the opposite sides of the first support part and the second support part. The central support part is fixed between the first support part and the second support part by the limiting parts. The central support part is an arc-shaped structure and includes at least one arc-shaped connecting plate. The arc-shaped connecting plate includes a first arc plate, a second arc plate, and a central arc plate. The first arc plate and the second arc plate are respectively arranged on both sides of the central arc plate.

[0007] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the first arc plate and the second arc plate are the same size and are adapted to the size of the limiting part, so that the first arc plate and the second arc plate can be inserted into the limiting part.

[0008] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the limiting part includes a first mating arc groove and a second mating arc groove, and the first mating arc groove and the second mating arc groove are arranged opposite to each other to form a cavity structure that restricts the first arc plate and the second arc plate.

[0009] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the arc-shaped connecting plate is one or a combination of multiple plates.

[0010] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the upper part of the central arc plate, the second support longitudinal plate, and the second support longitudinal plate are all provided with lifting holes, and the first support horizontal plate, the second support horizontal plate, the third support horizontal plate, and the fourth support horizontal plate are all provided with mating holes.

[0011] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, a support structure is provided on the mating hole. The support structure includes a triangular support frame and a support body. The triangular support frame is connected to the mating hole, and the support body is horizontally arranged on the triangular support frame. One end of the support body is connected to the mating hole, and the other end is connected to the steel support inside the foundation pit.

[0012] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the first support part is an H-shaped structure, and the first support part specifically includes a first support horizontal plate, a second support horizontal plate and a first support vertical plate. The first support vertical plate is arranged perpendicular to the first support horizontal plate and the second support horizontal plate; the limiting part is arranged on the first support vertical plate.

[0013] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the first supporting longitudinal plate is located at the center of the first supporting transverse plate and the second supporting transverse plate, and the limiting part is located at the center of the first supporting longitudinal plate.

[0014] Based on the above-mentioned arc-shaped prefabricated steel enclosure structure, the second support part is an H-shaped structure. The second support part specifically includes a third support horizontal plate, a fourth support horizontal plate, and a second support vertical plate. The second support vertical plate is arranged perpendicular to the third support horizontal plate and the fourth support horizontal plate. The limiting part is arranged on the second support vertical plate. The second support vertical plate is located at the center of the third support horizontal plate and the fourth support horizontal plate. The limiting part is located at the center of the second support vertical plate.

[0015] This solution also provides a fencing system comprising multiple steel enclosure structures connected to adjacent steel enclosure structures via a central support.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This solution provides a novel prefabricated steel retaining structure. The process is simple and easy to understand, enabling the construction of retaining structures for deep foundation pits under varying depths and geological conditions. It eliminates the need for pre-drilling, facilitates the insertion of modular steel sections, and simplifies waler connections. Furthermore, this solution addresses the issues of low stiffness and susceptibility of sheet piles, improves the reusability of retaining structures in deep foundation pits, and ensures the stability of the retaining structure during excavation.

[0018] 2. When support is required for the foundation pit, the first and second support parts are first inserted vertically downwards into the ground using a vibrating device. During the insertion process, the verticality of the pile needs to be checked. Then, the central support part is inserted into the limiting part and slowly inserted into the ground to finally form the foundation pit support structure. This solution is safe, clean, energy-saving, low-carbon, and environmentally friendly. It allows for resource recycling, controllable pollution emissions, and is economical and reliable. It is a highly efficient, energy-saving, environmentally friendly, and sustainable green foundation pit support technology. This technology can completely replace the above-mentioned traditional support structure process and has advantages such as short construction period, low construction cost, small environmental impact, and good safety performance.

[0029] Example 1

[0030] like Figure 1 or Figure 3 As shown, this utility model provides a technical solution:

[0031] An arc-shaped prefabricated steel enclosure structure includes, but is not limited to, a first support part 1, a second support part 2, and a central support part 3. The first support part 1 and the second support part 2 are symmetrically arranged on both sides of the central support part 3. Limiting parts 4 for supporting the central support part 3 are provided on the opposite sides of the first support part 1 and the second support part 2. The central support part 3 is engaged and fixed between the first support part 1 and the second support part 2 by the limiting parts 4. The central support part 3 can be an arc-shaped structure and can include at least one arc-shaped connecting plate. The arc-shaped connecting plate can include a first arc plate 311, a second arc plate 312, and a central arc plate 313. The first arc plate and the second arc plate are respectively arranged on both sides of the central arc plate.

[0032] Based on the above structure, when the foundation pit needs to be supported, the first support part 1 and the second support part 2 are first inserted vertically downwards into the ground slowly using a vibrating device. During the insertion process, the verticality of the pile needs to be checked. Then, the central support part 3 is inserted into the limiting part 4 and slowly inserted into the ground, finally forming the foundation pit support structure. This solution is safe, clean, energy-saving, low-carbon, and environmentally friendly. It allows for resource recycling, controllable pollution emissions, and is economical and reliable. It is a green foundation pit retaining technology that is efficient, energy-saving, environmentally friendly, and sustainable. This technology can completely replace the above-mentioned traditional retaining structure process and has advantages such as short construction period, low construction cost, small environmental impact, and good safety performance.

[0033] As an example, the first arc plate and the second arc plate are the same size and are adapted to the size of the limiting part 4, so that the first arc plate and the second arc plate can be inserted into the limiting part 4.

[0034] The limiting part 4 may include a first mating arc groove 314 and a second mating arc groove 315. The first mating arc groove and the second mating arc groove are arranged opposite to each other to form a cavity structure that limits the first arc plate and the second arc plate.

[0035] Based on the above structure, this solution uses a simple arc-shaped structure and an arc groove to form a complete support unit, which can be effectively and stably inserted into the ground to support the foundation pit, and can also be easily removed for recycling.

[0036] The curved connecting plate can be one or a combination of multiple plates.

[0037] As an example, the first support part 1 can be an H-shaped structure. Specifically, the first support part 1 can include a first support horizontal plate 11, a second support horizontal plate 12 and a first support vertical plate 13. The first support vertical plate 13 is arranged perpendicular to the first support horizontal plate 11 and the second support horizontal plate 12. The limiting part 4 is arranged on the first support vertical plate 13.

[0038] Based on the above structure, by setting the first support part 1 as an H-shaped structure, when the first support part 1 is pressed into the ground, on the one hand, the parallelism of the end can be accurately determined, and on the other hand, it can be ensured that the first support part 1 has lateral and longitudinal forces in the ground after insertion, so that the support effect of the first support part 1 is better.

[0039] As an example, the first support longitudinal plate 13 is located at the center of the first support transverse plate 11 and the second support transverse plate 12, and the limiting part 4 is located at the center of the first support longitudinal plate 13.

[0040] Based on the above structure, by setting the first support longitudinal plate 13 at the center of the first support transverse plate 11 and the second support transverse plate 12, the accuracy of the force on the entire first support part 1 can be guaranteed. Similarly, by setting the limiting part 4 at the center of the first longitudinal plate, the position of the central support part 3 after installation can also be in the center, ensuring the stability of the structure after subsequent assembly.

[0041] As an example, the second support part 2 can be an H-shaped structure. Specifically, the second support part 2 can include a third support horizontal plate 21, a fourth support horizontal plate 22, and a second support vertical plate 23. The second support vertical plate 23 is arranged perpendicular to the third support horizontal plate 21 and the fourth support horizontal plate 22. The limiting part 4 is arranged on the second support vertical plate 23.

[0042] Based on the above structure, by setting the second support part 2 as an H-shaped structure, when the second support part 2 is pressed into the ground, on the one hand, the parallelism of the end can be accurately determined, and on the other hand, it can be ensured that the second support part 2 has lateral and longitudinal forces in the ground after insertion, so that the support effect of the second support part 2 is better.

[0043] As an example, the second support longitudinal plate 23 is located at the center of the third support transverse plate 21 and the fourth support transverse plate 22, and the limiting part 4 is located at the center of the second support longitudinal plate 23.

[0044] Based on the above structure, by setting the second support longitudinal plate 23 at the center of the third support transverse plate 21 and the fourth support transverse plate 22, the accuracy of the force on the entire second support part 2 can be guaranteed. Similarly, by setting the limiting part 4 at the center of the second longitudinal plate, the position of the central support part 3 after installation can also be in the center, ensuring the stability of the structure after subsequent assembly.

[0045] As an example, the central arc plate, the second support longitudinal plate 23, and the upper part of the second support longitudinal plate 23 are all provided with lifting holes 5, and the first support horizontal plate 11, the second support horizontal plate 12, the third support horizontal plate 21, and the fourth support horizontal plate 22 are all provided with mating holes 7.

[0046] A support structure is provided on the mating hole 7. The support structure may include a triangular support frame 8 and a support body 9. The triangular support frame 8 is connected to the mating hole 7, and the support body 9 is horizontally arranged on the triangular support frame 8. One end of the support body 9 is connected to the mating hole 7, and the other end is connected to the steel support 10 inside the foundation pit.

[0047] Based on the above structure, the triangular support frame 8 in this solution can provide pre-support force for the support body 9, which facilitates the assembly of the support body 9. The support body 9 connects the adjacent first support plate and third support plate, as well as the second support plate and fourth support plate into one unit, and finally connects with the internal steel support 10 to form a stable support structure.

[0048] Example 2

[0049] like Figure 4 and Figure 5 As shown, this utility model provides a technical solution:

[0050] A prefabricated fencing system includes multiple steel enclosure structures, with adjacent steel enclosure structures connected by a central support 3. This ultimately forms an integral structure that supports the foundation pit.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
