[0002] Currently, steel sheet piles are commonly used in the construction of foundation pits. As a type of steel structure with interlocking devices on its edges, steel sheet piles can be freely combined to form continuous and tight retaining or water-retaining walls. They play an important role in engineering fields such as construction, water conservancy, and ports. Their unique advantages, such as high strength, lightweight, good water-tightness, high durability, simple construction, short construction period, and significant environmental protection effects, make steel sheet piles an indispensable support material in modern engineering.

[0003] However, after the foundation pit is enclosed by sheet piles, a support structure is usually needed to support the sheet piles. However, the current support structure is usually a fixed-length steel beam, which usually needs to be spliced ​​to fit the size of the foundation pit. The construction operation is time-consuming and labor-intensive, which brings a lot of inconvenience to the support construction of the sheet piles in the foundation pit. To this end, the applicant proposes a support structure for sheet piles in foundation pits to solve the above problems. Utility Model Content

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a support structure for foundation pit steel sheet piles includes:

[0030] Positioning mechanism 1 and support mechanism 2 assembled between positioning mechanism 1;

[0031] The positioning mechanism 1 includes a second right-angle positioning seat 15, a sleeve 13 is fixedly installed on the top of the second right-angle positioning seat 15, a telescopic column 12 is sleeved on the top of the sleeve 13, and a first right-angle positioning seat 11 is fixedly installed on the top of the telescopic column 12.

[0032] The support mechanism 2 includes a first support frame 21 and a second support frame 22, which are respectively fixedly installed on the inner wall of the first right-angle positioning seat 11. The second support frame 22 is slidably installed inside the first support frame 21. A storage cavity 210 is opened inside the second support frame 22. A threaded sleeve 29 is rotatably installed inside the storage cavity 210. A threaded rod 25 is threadedly engaged inside the threaded sleeve 29. A movable block 27 is fixedly installed at one end of the threaded rod 25. The movable block 27 is slidably installed inside the first support frame 21.

[0033] As can be seen from the above, during use, the positioning mechanism 1 is positioned at the four corners of the pit according to the size of the pit. The second right-angle positioning seat 15 can be attached to the bottom of the pit for support. The telescopic column 12 can be extended and retracted along the sleeve 13, which can easily adjust the support mechanism 2 to a suitable height according to the height of the pit. At the same time, the first right-angle positioning seat 11 can be positioned at the four corners of the inner wall of the pit for support.

[0034] A square structure can be formed by several sets of support mechanisms 2. By utilizing the sliding action between the first support frame 21 and the second support frame 22, the square structure can slide according to the four corner positioning positions of the positioning mechanism 1. This allows the square structure to be size adjustable and can be flexibly adjusted according to the size of the foundation pit. No splicing or assembly is required, which saves time and effort in construction and brings more convenience to the support construction of steel sheet piles in the foundation pit.

[0035] The first support frame 21 limits the movement of the movable block 27, preventing the threaded rod 25 from rotating. The rotation of the threaded sleeve 29 allows the threaded rod 25 to move horizontally. After the threaded rod 25 extends out of the receiving cavity 210, it can push the movable block 27 to slide, allowing the movable block 27 to abut against the inner wall of the first support frame 21. This expands the support between the first support frame 21 and the second support frame 22, enabling the support mechanism 2 to fit tightly against the sheet pile in the foundation pit. This creates a stable ring support effect around the sheet pile, preventing it from tilting and improving the support effect.

[0036] Depend on Figure 2 It can be seen that the inner walls of the first right-angle positioning seat 11 and the second right-angle positioning seat 15 are both fixedly installed with reinforcing blocks 17, which are triangular in shape.

[0037] As can be seen from the above, the structural strength of the first right-angle positioning seat 11 and the second right-angle positioning seat 15 can be improved by reinforcing block 17, so that they are less likely to deform when supported at the four corners of the steel sheet pile in the foundation pit, thus improving the firmness.

[0038] For details, please refer to Figure 2 As shown, a fixing cone 16 is fixedly installed at the bottom of the second right-angle positioning seat 15, and the sleeve 13 and the telescopic column 12 are fixed together by a fixing knob 14.

[0039] As can be seen from the above, when the second right-angle positioning seat 15 is supported at the bottom of the pit, the fixing cone 16 can be inserted into the ground, which can easily fix the second right-angle positioning seat 15 and prevent the second right-angle positioning seat 15 from shifting. The telescopic column 12 can be easily fixed by the fixing knob 14, and the support mechanism 2 can be easily fixed at a suitable height.

[0040] For details, please refer to Figure 3 As shown, the first support frame 21 and the second support frame 22 are slidably installed together by a slider 23, and the inner wall of the first support frame 21 is provided with a groove 26 for the slider 23 to slide.

[0041] As can be seen from the above, the sliding groove 26 limits the slider 23, allowing the slider 23 to slide along the sliding groove 26, which facilitates the mutual sliding between the first support frame 21 and the second support frame 22, and makes it convenient to adjust the operation according to the size of the pit.

[0042] Example 2:

[0043] refer to Figure 5 As shown, a drive gear 28 is rotatably mounted on the inner wall of the storage cavity 210, and teeth 211 arranged in a ring array are distributed on one side of the threaded sleeve 29, which mesh with the drive gear 28.

[0044] As can be seen from the above, by driving the drive gear 28 to rotate, the meshing action between the drive gear 28 and the teeth 211 can be used to drive the threaded sleeve 29 to rotate, and the rotation of the threaded sleeve 29 can be used to drive the threaded rod 25 to move horizontally.

[0045] refer to Figure 1 and Figure 4 As shown, an adjustment handle 24 is fixedly installed on one side of the drive gear 28, and the adjustment handle 24 is located on the periphery of the second support frame 22.

[0046] As can be seen from the above, by adjusting the throttle 24, the drive gear 28 can be driven to rotate relatively easily, which can easily control the threaded rod 25 to extend out of the storage cavity 210 and control the threaded rod 25 to retract into the storage cavity 210, bringing more convenience to the operation.

[0047] refer to Figure 5 As shown, the threaded sleeve 29 is rotatably installed between the receiving cavity 210 and the receiving cavity 212 via the rotating groove 212, and the other end of the threaded rod 25 is slidably installed between the receiving cavity 210 and the sliding block 213.

[0048] As can be seen from the above, the rotating groove 212 allows the threaded sleeve 29 to rotate within the receiving cavity 210, while preventing the threaded sleeve 29 from falling out of the receiving cavity 210, thus enabling convenient and stable driving of the threaded rod 25 for movement.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
