Description

Technical Field

[0001] This utility model relates to the field of sheet piles, and in particular to a sheet pile support structure. Background Technology

[0002] Currently, Chinese utility model patent CN219157708U discloses a steel sheet pile support structure for foundation pits. While this support structure allows for interlocking assembly, improving installation efficiency, it presents other problems during use. For example, it lacks height adjustment functionality, resulting in a height difference between the two opposing sheet piles after driving. This causes the ends of the steel section to misalign with pre-drilled through holes during installation, with one end potentially misaligning with the through hole on the sheet pile. External tools are needed to forcibly stretch the steel section, which is time-consuming and labor-intensive, and makes it difficult to pull the sheet pile out. Furthermore, when the sheet pile is driven into dense sand, it experiences stronger soil pressure and adhesion. In such cases, conventional clamping and pulling methods may result in slippage, failing to provide an effective pulling point. The sand must be gradually removed to release the soil pressure. To address these issues, we propose a steel sheet pile support structure. Utility Model Content

[0003] The purpose of this utility model is to provide a steel sheet pile support structure that solves the problems of existing steel sheet pile support structures lacking height adjustment function and being inconvenient to pull the sheet piles outward.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel sheet pile support structure, including a first pile plate, a second pile plate provided on the back of the first pile plate, a fixing frame bolted to the opposite side of the first pile plate and the second pile plate, a connecting block provided inside the fixing frame, two screws provided through the top of the connecting block, both ends of the screws being welded to the inside of the fixing frame, an adjusting nut threadedly connected to the bottom end of the surface of the screws, through grooves provided inside the first pile plate and the second pile plate, a first fixing member and a second fixing member respectively provided inside and outside the first pile plate and the second pile plate, a first threaded sleeve installed on one side of the first fixing member, and a second threaded sleeve threadedly connected to the first threaded sleeve on one side of the second fixing member, wherein the first threaded sleeve is externally threaded and the second threaded sleeve is internally threaded.

[0005] The above technical solution has a height adjustment function, which can compensate for the distance difference generated when the steel sheet pile is driven, facilitate the installation and fixing of the steel section, has good flexibility, and can also make it easy to pull the pile sheet outward. The operation is simple and convenient, can avoid the passage of sand or fluid, and facilitates the hook to pass through for leverage, making it highly practical.

[0006] The present invention is further configured such that both sides of the first pile plate and the second pile plate are integrally stamped as interlocking parts.

[0007] By adopting the above technical solution, the interlocking part can facilitate the assembly and guidance of subsequent pile plates.

[0008] The present invention is further configured such that a fixing nut is threadedly connected to the top end of the screw surface.

[0009] By adopting the above technical solution, the connecting block can be limited by the setting of the fixing nut, which can prevent the steel section from shaking after it is fixed.

[0010] The present invention is further configured such that: the surface of the connecting block is provided with mounting holes.

[0011] By adopting the above technical solution, the installation holes make it easy to fix the steel profile to the connecting block with screws, reducing the trouble of temporary drilling.

[0012] The present invention is further configured such that sealing rings are slidably fitted onto the surfaces of both the first and second threaded sleeves.

[0013] By adopting the above technical solution and setting the sealing ring, the sealing effect between the first and second fixing members and the first pile plate can be improved.

[0014] The present invention is further configured such that the surfaces of the first pile plate and the second pile plate are both coated with anti-corrosion coating.

[0015] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects on the surfaces of the first and second pile plates can be improved.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model involves first driving the first and second pile plates into designated positions, then lifting the steel profile and fixing one side to the connecting block on the first pile plate. Once one side is fixed, the other side is lifted. If it is higher than the other connecting block, the adjusting nut on the second pile plate is grasped with a tool and rotated upwards. When the adjusting nut rotates, it will push the connecting block upwards. Finally, once both sides of the steel profile are fixed, the fixing nut is rotated downwards to the bottom. This design provides height adjustment, which can compensate for the distance difference generated when driving the steel sheet piles, making it convenient for personnel to install and fix the steel profile, and offering good flexibility.

[0018] 2. This utility model allows one hand to hold the first fixing member and insert the first threaded sleeve into the through groove. After the first threaded sleeve is inserted, the other hand holds the second fixing member. After holding the second fixing member, the second threaded sleeve is also inserted into the through groove and screwed into the first threaded sleeve. Then, the first and second fixing members are rotated to form a fixed seal to block the through groove. When removing the sheet pile, the first and second fixing members can be separated and removed. This makes it easy to pull the sheet pile outward. The operation is simple and convenient, avoids the passage of sand or fluid, and facilitates the hook to pass through for leverage. It is highly practical. Attached Figure Description
